CHAPTER ONE

Spacebound


A thousand miles above Earth's surface the great space platform sped
from daylight into darkness. Once every two hours it circled the earth
completely, spinning along through space like a mighty wheel of steel and
plastic.

Through a telescope on Earth the platform looked to be a lifeless, lonely
disk, but within it, hundreds of spacemen and Planeteers went about their
work.

In a ready room at the outer edge of the platform, a Planeteer officer
faced a dozen slim, black-clad young men who wore the single golden
orbits of lieutenants. This was a graduating class, already commissioned,
having a final informal get-together.

The officer, who wore the three-orbit insignia of a major, was lean and
trim. His short-cropped hair covered his head like a gray fur skull cap.
One cheek was marked with the crisp whiteness of an old radiation burn.

"Stand easy," he ordered briskly. "The general instructions of the
Special Order Squadrons say that it's my duty as senior officer to make a
farewell speech. I intend to make a speech if it kills me--and you, too."

The dozen new officers facing him broke into grins. Maj. Joe Barris had
been their friend, teacher, and senior officer during six long years of
training on the space platform. He could no more make a formal speech
than he could breathe high vacuum, and they all knew it.

Lt. Richard Ingalls Peter Foster, whose initials had given him the
nickname "Rip," asked, "Why don't you sing for us instead, Joe?"

Major Barris fixed Rip with a cold eye. "Foster, three orbital turns,
then front and center."

Rip obediently spun around three times, then walked forward and stood at
attention, trying to conceal his grin.

"Foster, what does SOS mean?"

"Special Order Squadrons, sir."

"Right. And what else does it mean?"

"It means 'Help!' sir."

"Right. And what else does it mean?"

"Superman or simp, sir."

This was a ceremony in which questions and answers never changed. It was
supposed to make Planeteer cadets and junior officers feel properly
humble, but it didn't work. By tradition, the Planeteers were the
cockiest gang that ever blasted through high vacuum.

Major Barris shook his head sadly. "You admit you're a simp, Foster. The
rest of you are simps, too, but you don't believe it. You've finished six
years on the platform. You've made a few little trips out into space.
You've landed on the moon a couple of times. So now you think you're
seasoned space spooks. Well, you're not. You're simps!"

Rip stopped grinning. He had heard this before. It was part of the
routine. But he sensed that this time Joe Barris wasn't kidding.

The major absently rubbed the radiation scar on his cheek as he looked
them over. They were like twelve chicks out of the same nest. They were
about the same size, a compact five feet eleven inches, 175 pounds. They
wore belted, loose black tunics over full trousers which gathered into
white cruiser boots. The comfortable uniforms concealed any slight
differences in build. All twelve were lean of face, with hair cropped to
the regulation half inch. Rip was the only redhead among them.

"Sit down," Barris commanded. "Here's my speech."

The twelve seated themselves on plastic stools. Major Barris remained
standing.

"Well," he began soberly, "you are now officers of the Special Order
Squadrons. You're Planeteers. You are lieutenants by order of the Space
Council, Federation of Free Governments. And--space protect you!--to
yourselves you're supermen. But never forget this: To ordinary spacemen,
you're just plain simps. You're trouble in a black tunic. They have about
as much use for you as they have for leaks in their air locks. Some of
the spacemen have been high-vacking for twenty years or more, and they're
tough. They're as nasty as a Callistan _teekal_. They like to eat
Planeteer junior officers for breakfast."

Lt. Felipe "Flip" Villa asked, "With salt, Joe?"

Major Barris sighed. "No use trying to tell you space chicks anything.
You're lieutenants now, and a lieutenant has the thickest skull of any
rank, no matter what service he belongs to."

Rip realized that Barris had not been joking, no matter how flippant his
speech. "Go ahead," he urged. "Finish what you were going to say."

"Okay. I'll make it short. Then you can catch the Terra rocket and take
your eight weeks' Earth leave. You won't really know what I'm talking
about until you've batted around space for a while. All I have to say
adds up to one thing. You won't like it, because it doesn't sound
scientific. That doesn't mean it isn't good science, because it is. Just
remember this: When you're in a jam, trust your hunch and not your head."

The twelve stared at him, openmouthed. For six years they had been taught
to rely on scientific methods. Now their best instructor and senior
officer was telling them just the opposite!

Rip started to object, but then he caught a glimmer of meaning. He stuck
out his hand. "Thanks, Joe. I hope we'll meet again."

Barris grinned. "We will, Rip. I'll ask for you as a platoon commander
when they assign me to cleaning up the goopies on Ganymede." This was the
major's idea of the worst Planeteer job in the solar system.

The group shook hands all around; then the young officers broke for the
door on the run. The Terra rocket was blasting off in five minutes, and
they were to be on it.

Rip joined Flip Villa, and they jumped on the high-speed track that would
whisk them to Valve Two on the other side of the platform. Their gear was
already loaded. They had only to take seats on the rocket, and their six
years on the space platform would be at an end.

"I wonder what it will be like to get back to high gravity," Rip mused.
The centrifugal force of the spinning platform acted as artificial
gravity, but it was considerably less than Earth's.

"We probably won't be able to walk straight until we get our Earth legs
back," Flip answered. "I wish I could stay in Colorado with you instead
of going back to Mexico City, Rip. We could have a lot of fun in eight
weeks."

Rip nodded. "Tough luck, Flip. But anyway, we have the same assignment."

Both Planeteers had been assigned to Special Order Squadron Four, which
was attached to the cruiser _Bolide_. The cruiser was in high space,
beyond the orbits of Jupiter and Saturn, doing comet research.

They got off the track at Valve Two and stepped through into the rocket's
interior. Two seats just ahead of the fins were vacant, and they slid
into them. Rip looked through the thick port beside him and saw the
distinctive blue glow of a nuclear drive cruiser sliding toward the
platform.

"Wave your eye stalks at that job," Flip said admiringly. "Wonder what
it's doing here."

The space platform was a refueling depot, where conventional chemical
fuel rockets topped off their tanks before flaming for space. The newer
nuclear drive cruisers had no need to stop. Their atomic piles needed new
neutron sources only once every few years, and they carried thousands of
tons of methane, compressed into solid form, for their reaction mass.

The voice horn in the rocket cabin sounded. "The SCN _Scorpius_ is
passing Valve Two, landing at Valve Eight."

"I thought that ship was with Squadron One on Mercury," Rip recalled.
"Wonder why they pulled it back here."

Flip had no chance to reply, because the chief rocket officer took up his
station at the valve and began to call the roll. Rip answered to his
name.

The rocket officer finished the roll, then announced: "Buttoning up in
twenty seconds. Blast off in forty-five. Don't bother with acceleration
harness. We'll fall free, with just enough flame going for control, after
ten seconds of retrothrust to de-orbit."

The ten-second-warning bell sounded, and, before the bell had ceased, the
voice horn blasted. "Get it! Foster, R.I.P., Lieutenant. Report to the
platform commander. Show an exhaust!"

Rip leaped to his feet. "Hold on, Flip. I'll see what the old man wants
and be right back."

"Get flaming," the rocket officer called. "Show an exhaust, like the man
said. This bucket leaves on time, and we're sealing the port."

Rip hesitated. The rocket would leave without him!

Flip said urgently, "You better ram it, Rip."

He knew he had no choice. "Tell my folks I'll make the next rocket," he
called, and ran. He leaped through the valve, jumped for the high-speed
track, and was whisked around the rim of the space platform.

He ran a hand through his short red hair, a gesture of bewilderment. His
records had cleared. So far as he knew, all his papers were in order, and
he had his next assignment. He couldn't figure why the platform commander
would want to see him. But the horn had called, "Show an exhaust!" which
meant to get there in a hurry.

He jumped off the track at the main crossrun and hurried toward the
center of the platform. In a moment he was at the commander's door,
waiting to be identified.

The door swung open, and a junior officer in the blue tunic and trousers
of a spaceman motioned him to the inner room. "Go in, Lieutenant."

"Thank you." He hurried into the commander's room and stood at attention.

Commander Jennsen, the Norwegian spaceman who had commanded the platform
since before Rip's arrival as a raw cadet, was dictating into his command
relay circuit. As he spoke, printed copies were being received in the
platform personnel office, at Special Order Squadron headquarters on
Earth, aboard the cruiser _Bolide_ in high space, and aboard the newly
landed cruiser _Scorpius_.

Rip listened, spellbound.

"Foster, R.I.P., Lieutenant, SOS. Serial seven-nine-four-three. Assigned
SOS Four. Change orders, effective this date-time. Cancel Earth leave.
Subject officer will report to commander, SCN _Scorpius_, with detachment
of nine men. Senior noncommissioned officer and second in command, Koa,
A.P., Sergeant Major, SOS. Serial two-nine-four-one. Commander of
_Scorpius_ will transport detachment to coordinates given in basic
cruiser astro-course; deliver orders to detachment en route. Take
required steps for maximum security. This is Federation priority A,
Space Council security procedures."

Rip swallowed hard. The highest possible priority, given by the
Federation itself, had canceled his leave. Not only that, but the cruiser
to which he was assigned was instructed to follow Space Council security
procedures, which meant that the job, whatever it was, was more urgent
than secret!

Commander Jennsen looked up and saw Rip waiting. He snapped, "Did you get
all of that?"

"Y-Yes, sir."

"You'll get written copies on the cruiser. Now flame out of here. Collect
your men and get aboard. The _Scorpius_ leaves in five minutes."

Rip ran. The realization hit him that the big nuclear cruiser had stopped
at the platform for the sole purpose of collecting him and nine enlisted
Planeteers.

The low gravity helped him cover the hundred yards to the personnel
office in five leaps. He swung to a stop by grabbing the push bar of the
office door. He yelled at the enlisted spaceman on duty. "Where do I find
nine men?"

The spaceman looked at him vacantly. "What for? You got a requisition,
Lieutenant?"

"Never mind requisitions," Rip snapped. "I've got to find nine Planeteers
and get them on the _Scorpius_ before it flames off."

The spaceman's face cleared. "Oh. You mean Koa's detachment. They left a
few minutes ago."

"Where. Where did they go?"

The spaceman shrugged. The doings of Planeteers were no concern of his.
His shrug said so.

Rip realized there was no use talking further. He ran down the long
corridor toward the outer edge of the platform. The enlisted men's squad
rooms were near Valve Ten. So was the supply department. His gear had
departed on the Terra rocket, and he couldn't go into space with only
the tunic on his back. He swung to the high-speed track and braced
himself as he sped along the platform's rim.

There was no moving track inward to the enlisted Planeteers' squad rooms.
He legged it down the corridor in long leaps, muttering apologies as
blue-clad spacemen and cadets moved to the wall to let him pass.

The squad rooms were on two levels. He looked in the upper ones and found
them deserted. The squads were on duty somewhere. He ran for the ladder
to the lower level, took the wrong one, and ended up in a snapper-boat
port. He had trained in the deadly little fighting rockets, and they
never failed to interest him. But there wasn't time to admire them now.
He went back up the ladder with two strong heaves, found the right
ladder, and dropped down without touching. His knees flexed to take up
the shock. He came out of the crouch facing a black-clad Planeteer
sergeant who snapped to rigid attention.

"Koa," Rip barked. "Where can I find him?"

"He's not here, sir. He and eight men left fifteen minutes ago. I don't
know where they went, sir."

Rip shot a worried glance at his wrist chronometer. He had two minutes
left before the cruiser departed. No more time now to search for his men.
He hoped the sergeant major had sense enough to be waiting at some
reasonable place. He went up the ladder hand over hand and sped down the
corridor to the supply room. The spaceman first class in charge of
supplies was turning an audio-mag through a hand viewer, chuckling at the
cartoons. At the sight of Rip's flushed, anxious face he dropped the
machine. "Yessir?"

"I need a spack. Full gear, including bubble."

"Yessir." The spaceman looked him over with a practiced eye. "One full
space pack. Medium-large, right, sir?"

"Correct." Rip took the counter stylus and inscribed his name, serial
number, and signature on the blank plastic sheet. Gears whirred as the
data was recorded.

The spaceman vanished into an inner room and reappeared in a moment
lugging a plastic case called a space pack, or "spack" for short. It
contained complete personal equipment for space travel. Rip grabbed it.
"Fast service. Thanks, Rocky." All spacemen were called "Rocky" if you
didn't know their names. It was an abbreviation for rocketeer, a title
all of them had once carried.

Valve Eight was some distance away. Rip decided a cross ramp would be
faster than the moving track. He swung the spack to his shoulder and made
his legs go. Seconds were ticking off, and he had an idea that the SCN
_Scorpius_ would make space on time, whether or not he arrived. He
lengthened his stride and rounded a turn by going right up on the wall,
using a powerful leg thrust against a ventilator tube for momentum.

He passed an observation port as he reached the platform rim, and caught
a glimpse of ruddy rocket exhaust flames outlined against the dark curve
of Earth. That would be the Terra rocket making its controlled fall to
home, with Flip aboard. Without slowing, he leaped across the high-speed
track, narrowly missing a senior space officer. He shouted his apologies,
and gained the entrance to Valve Eight just as the high buzz of the
radiation warning sounded, signaling a nuclear drive cruiser preparing
to take off.

Nine faces of assorted colors and expressions turned to him. He had a
quick impression of black tunics and trousers. He had found his
detachment! Without slowing, he called, "Follow me!"

The cruiser's safety officer had been keeping an eye on the clock, his
forehead creased in a frown as he saw that only a few seconds remained
to departure time. He walked to the valve opening and looked out. If his
passengers were not in sight, he would have to reset the clock.

Rip went through the valve opening at top speed. He crashed head on into
the safety officer.

The safety officer was driven across the deck, his arms pumping for
balance. He grabbed at the nearest thing, which happened to be the deputy
cruiser commander.

The preset clock reached firing time. The valve slid shut and the takeoff
bell reverberated through the ship.

And so it happened that the spacemen of the SCN _Scorpius_ turned their
valves, threw their controls and disengaged their boron control rods, and
the great cruiser flashed into space--while the deputy commander and the
safety officer were completely tangled with a very flustered and unhappy
new Planeteer lieutenant.

Sergeant Major Koa and his men had made it before the valve closed. Koa,
a seven-foot Hawaiian, took in the situation and said crisply in a voice
all could hear, "I'll bust the bubble of any son of a space sausage who
laughs!"



CHAPTER TWO

Rake That Radiation!


The deputy commander and the safety officer got untangled and hurried to
their post, with no more than black looks at Rip. He got to his feet, his
face crimson with embarrassment. A fine entrance for a Planeteer officer,
especially one on his first orders!

Around him the spacemen were settling in their acceleration seats or
snapping belts to safety hooks. From the direction of the stern came a
rising roar as methane, heated to a liquid, dropped into the blast tubes,
flaming into pure carbon and hydrogen under the terrible heat of the
atomic drive.

Rip had to lean against the acceleration. Fighting for balance, he picked
up his spack and made his way to the nine enlisted Planeteers. They had
braced against the ship's drive by sitting with backs against bulkheads
or by lying flat on the magnesium deck. Sergeant Major Koa was seated
against a vertical brace, his brown face wreathed in a grin.

Rip looked him over carefully. There was a saying among the Planeteers
that an officer was only as good as his senior sergeant. Koa's looks were
reassuring. His face was good-humored, but he had a solid jaw and a mouth
that could get tough when necessary. Rip wondered a little at his size.
Big men usually didn't go to space; they were too subject to space
sickness. Koa must be a special case.

Rip slid to the floor next to the sergeant major and stuck out his hand.
He sensed the strength in Koa's big fist as it closed over his.

Koa said, "Sir, that was the best _fleedle_ I've ever seen an earthling
make. You been on Venus?"

Rip eyed him suspiciously, wondering if the big Planeteer was laughing at
him. Koa was grinning, but it was a friendly grin. "What is a _fleedle_?"
Rip demanded. "I've never been on Venus."

"It's the way the water hole people fight," Koa explained. "They're like
a bunch of rubber balls when they get to fighting. They ram each other
with their heads."

Rip searched his memory for data on Venus. He couldn't recall any mention
of _fleedling_. Venusians, if his memory was right, had a sort of blowgun
as a main weapon. He told Koa so.

The sergeant major nodded. "That's when they mean business, Lieutenant.
_Fleedling_ is more like us fighting with our fists. Sort of a sport.
Great Cosmos! The way they dive at each other is something to see."

Rip grinned. "I didn't know I was going to _fleedle_ those officers. It
isn't the way I usually enter a cruiser." He hadn't entered many. He
added, "I suppose I ought to report to someone."

Koa shook his head. "No use, sir. You can't walk around very well until
the ship reaches _Brennschluss_. Besides, you won't find any space
officers who'll talk to you."

Rip stared. "Why not?"

"Because we're Planeteers. They'll give us the treatment. They always do.
When the commander of this bucket gets good and ready, he'll send for
you. Until then, we might as well take it easy." He pulled a bar of
Venusian _chru_ from his pocket. "Have some. It'll make breathing
easier."

The terrific acceleration made breathing a little uncomfortable, but it
was not too bad. The chief effect was to make Rip feel as though a ton
of invisible feathers were crushing him against the vertical brace.
He accepted a bite of the bittersweet vegetable candy and munched
thoughtfully. Koa seemed to take it for granted that the spacemen would
give them a rough time.

He asked, "Aren't there any spacemen who get along with the Special Order
Squadrons?"

"Never met one." Koa chewed chru. "And I was on the _Icarus_ when the
whole thing started."

Rip looked at him in surprise. Koa didn't seem that old. The bad feeling
between spacemen and the Special Order Squadrons had started about
eighteen years ago, when the cruiser _Icarus_ had taken the first
Planeteers to Mercury.

He reviewed the history of the expedition. The spacemen's job had been to
land the newly created Special Order Squadron on the hot planet. The job
of the squadron was to explore it. Somehow confusion developed, and the
spacemen, including the officers, later reported that the squadron had
instructed them to land on the sun side of Mercury, which would have
destroyed the spaceship and its crew, or so they believed at the time.

The commanding officer of the squadron denied issuing such an order. He
said his instructions were to land as close as possible to the sun side,
but not on it. Whatever the truth--and Rip believed the SOS version, of
course--the crew of the _Icarus_ mutinied, or tried to. They made the
landing on Mercury with squadron guns pointed at their heads. Of course,
they found that a sun-side landing wouldn't have hurt the ship. The whole
affair was pretty well hushed up, but it produced bad feeling between the
Special Order Squadrons and the spacemen. "Trigger-happy space bums," the
spacemen called them, and much worse, besides.

The men of the Special Order Squadrons, searching for a handy nickname,
had called themselves Planeteers, because most of their work was on the
planets. As Maj. Joe Barris had told the officers of Rip's class, "You
might say the spacemen own space, but we Planeteers own everything solid
that's found in it."

The Planeteers were the specialists--in science, exploration,
colonization, and fighting. The spacemen carried them back and forth,
kept them supplied, and handled their message traffic. The Planeteers did
the hard work and the important work--or so they believed.

To become a Planeteer, a recruit had to pass rigid intelligence,
physical, aptitude, and psychological tests. Fewer than fifteen out of
each one hundred who applied were chosen. Then there were two years of
hard training on the space platform and the moon before a recruit was
finally accepted as a Planeteer private. Out of each fifteen who started
training, an average of five fell by the wayside.

For Planeteer officers, the requirements were even tougher. Only one out
of each five hundred applicants finally received a commission. Six years
of training made them proficient in the techniques of exploration,
fighting, rocketeering, and both navigation and astrogation. In addition,
each became a full-fledged specialist in one field of science. Rip's
specialty was astrophysics.

Sergeant Major Koa continued, "That business on the _Icarus_ started the
war, but both sides have been feeding it ever since. I have to admit that
we Planeteers lord it over the spacemen like we were old man Cosmos
himself. So they get back at us with dirty little tricks while we're on
their ships. We command on the planets, but they command in space. And
they sure get a great big nuclear charge out of commanding us to do the
dirty work!"

"We'll take whatever they hand us," Rip assured him, "and pretend we like
it fine." He gestured at the other Planeteers. "Tell me about the men,
Koa."

"They're a fine bunch, sir. I handpicked them myself. The one with the
white hair is Corporal Nels Pederson, from Sweden. I served with him at
Marsport, and he's a real tough spacewalker in a fight. The other
corporal is Paulo Santos. He's from the Philippines, and the best
snapper-boat gunner you ever saw."

He pointed out the six privates. Kemp and Dowst were Americans. Bradshaw
was an Englishman, Trudeau a Frenchman, Dominico an Italian, and Nunez a
Brazilian.

Rip liked their looks. They were as relaxed as acceleration would allow,
but you got the impression that they would leap into action in a
microsecond if the word were given. He couldn't imagine what kind of
assignment was waiting, but he was satisfied with his Planeteers. They
looked capable of anything.

He made himself as comfortable as possible and encouraged Koa to talk
about his service in the Special Order Squadrons. Koa had plenty to tell,
and he talked interestingly. Rip learned that the tall Hawaiian had been
to every planet in the system, had fought the Venusians on the central
desert, and had mined nuclite with SOS One on Mercury. He also found that
Koa was one of the seventeen pure-blooded Hawaiians left. During the
three hours that acceleration kept them from moving around the ship, Rip
got a new view of space and of service with the SOS--it was the view of a
Planeteer who had spent years around the Solar System.

"I'm glad they assigned you to me," Rip told Koa frankly. "This is my
first job, and I'll be pretty green, no matter what it is. I'll depend
on you for a lot of things."

To his surprise, Koa thrust out his hand. "Shake, Lieutenant." His grin
showed strong white teeth. "You're the first junior officer I ever met
who admitted he didn't know everything about everything. You can depend
on me, sir. I won't steer you into any meteor swarms."

Koa had half turned to shake hands. Suddenly he spun on around, banging
his head against the deck. Rip felt a surge of relaxing muscles that had
been braced against acceleration. At the same time, silence flooded in on
them. Rip murmured "_Brennschluss_," and the murmur was like a trumpet
blast.

The _Scorpius_ had reached velocity, and the nuclear drive had cut out.
From terrific acceleration, they had dropped to zero. The ship was making
high speed, but velocity cannot be felt. For the moment the men were
weightless.

A nearby spaceman had heard Rip's comment. He spoke in an undertone to
the man nearest. His voice was pitched low enough that Rip couldn't
object officially, but loud and clear enough to be heard by everyone.

"Get this, gang. The Planeteer officer knows what _Brennschluss_ is. He
doesn't look old enough to know which end his bubble goes on."

Rip started to his feet, but Koa's hand on his arm restrained him. With a
violent kick, the big sergeant major shot through the air. His line of
flight took him past the spaceman, and somehow their arms got linked. The
spaceman was jerked from his post, and the two came to a stop against the
ceiling.

Koa's voice echoed through the ship. "Sorry. I'm not used to no-weight.
Didn't mean to grab you. Here, I'll help you back to your post."

He whirled the helpless spaceman like a bag of feathers and slung him
through the air. The force of the action only flattened Koa against the
ceiling, but the hapless spaceman shot forward head first and landed with
a clang against the bulkhead. He didn't hit hard enough to break any
bones, but he would carry a bump on his head for a day or two.

Koa's voice floated after him. "Great Cosmos! I sure am sorry, spaceman.
I guess I don't know my own strength." He kicked away from the ceiling,
landing accurately at Rip's side. He added in a hard voice all could
hear, "They sure are a nice gang, these spacemen. They never say anything
about Planeteers."

No spaceman answered, but Koa's meaning was clear. No spaceman had better
say anything about the Planeteers! Rip saw that the deputy commander and
the safety officer had appeared not to notice the incident. Technically,
there was no reason for an officer to take action. It had all been an
"accident." He smiled. There was a lot he had to learn about dealing with
spacemen, a lot Koa evidently knew very well indeed.

Suddenly he began to feel weight. The ship was going into rotation. The
feeling increased until he felt normally heavy again. There was no other
sensation, even though the space cruiser was now spinning on its axis
through space at unaltered speed. The centrifugal force produced by the
spinning gave them an artificial gravity.

Now that he thought about it, _Brennschluss_ had come pretty early. The
trip apparently was going to be a short one. _Brennschluss_--funny, he
thought, how words stay on in a language, even after their original
meaning is changed. _Brennschluss_ was German for "burn out." It was
rocket talk, and it meant the moment when all the fuel in a rocket burned
out. It had come into common use because the English "burn out" could
also mean that the engine itself had burned out. The German word meant
only the one thing. Now, in nuclear drive ships, the same word was used
for the moment when power was cut off.

Words interested him. He started to mention it to Koa just as the
telescreen lit up. An officer's face appeared. "Send that Planeteer
officer to the commander," the face said. "Tell him to show an exhaust."

Rip called instantly to the safety officer. "Where's his office?"

The safety officer motioned to a spaceman. "Show him, Nelson."

Rip followed the spaceman through a maze of passages, growing more
weightless with each step. The closer to the center of the ship they
went, the less he weighed. He was drawing himself along by plastic pull
cords when they finally reached the door marked COMMANDER.

The spaceman left without a word or a salute. Rip pushed the lock bar and
pulled himself in by grabbing the door frame. He couldn't help thinking
it was a rather undignified way to make an entrance.

Seated in an acceleration chair, a safety belt across his middle,
was Space Commander Kevin O'Brine, an Irishman out of Dublin. He was
short, as compact as a deto-rocket, and obviously unfriendly. He had a
mathematically square jaw, a lopsided nose, green eyes, and sandy hair.
He spoke with a pronounced Irish brogue.

Rip started to announce his name, rank, and the fact that he was
reporting as ordered. Commander O'Brine brushed his words aside and
stated flatly, "You're a Planeteer. I don't like Planeteers."

Rip didn't know what to say, so he kept still. But sharp anger was rising
inside of him.

O'Brine went on. "Instructions say I'm to hand you your orders en route.
They don't say when. I'll decide that. Until I do decide, I have a job
for you and your men. Do you know anything about nuclear physics?"

Rip's eyes narrowed. He said cautiously, "A little, sir."

"I'll assume you know nothing. Foster, the designation SCN means Space
Cruiser, Nuclear. This ship is powered by a nuclear reactor--in other
words, an atomic pile. You've heard of one?"

Rip controlled his voice, but his red hair stood on end with anger.
O'Brine was being deliberately insulting. This was stuff any Planeteer
recruit knew. "I've heard, sir."

"Fine. It's more than I had expected. Well, Foster, a nuclear reactor
produces heat. Great heat. We use that heat to turn a chemical called
methane into its component parts. Methane is known as marsh gas, Foster.
I wouldn't expect a Planeteer to know that. It is composed of carbon and
hydrogen. When we pump it into the heat coils of the reactor, it breaks
down and creates a gas that burns and drives us through space. But that
isn't all it does."

Rip had an idea what was coming, and he didn't like it. Nor did he like
Commander O'Brine. It was not until much later that he learned that
O'Brine had been on his way to Terra, to see his family for the first
time in four years, when the cruiser's orders were changed. To the
commander, whose assignments had been made necessary by the needs of the
Special Order Squadrons, it was too much. So he took his disappointment
out on the nearest Planeteer, who happened to be Rip.

"The gases go through tubes," O'Brine went on. "A little nuclear material
also leaks into the tubes. The tubes get coated with carbon, Foster.
They also get coated with nuclear fuel. We use thorium. Thorium is
radioactive. I won't give you a lecture on radioactivity, Foster. But
thorium mostly gives off the kind of radiation known as alpha particles.
Alpha is not dangerous unless breathed or eaten. It won't go through
clothes or skin. But when mixed with fine carbon, thorium alpha
contamination makes a mess. It's a dirty mess, Foster--so dirty that
I don't want my spacemen to fool with it.

"I want you to take care of it instead--you and your men. The deputy
commander will assign you to a squad room. Settle in, then draw equipment
from the supply room and get going. When I want to talk to you again,
I'll call for you. Now blast off, Lieutenant, and rake that radiation.
Rake it clean."

Rip forced a bright and friendly smile. "Yes, sir," he said sweetly.
"We'll rake it so clean you can see your face in it, sir." He paused,
then added politely. "If you don't mind looking at your face, sir--to see
how clean the tubes are, I mean."

Rip turned and got out of there.

Koa was waiting in the passageway outside. Rip told him what had
happened, mimicking O'Brine's Irish accent.

The sergeant major shook his head sadly. "This is what I meant,
Lieutenant. Cruisers don't clean their tubes more'n once in ten
accelerations. The commander is just thinking up dirty work for us
to do, like I said."

"Never mind," Rip told him. "Let's find our squad room and get settled,
then draw some protective clothing and equipment. We'll clean his tubes
for him. Our turn will come later."

He remembered the last thing Joe Barris had said, only a few hours
before. _Joe was right_, he thought. _To ourselves we're supermen, but to
the spacemen we're just simps._ Evidently O'Brine was the kind of space
officer who ate Planeteers for breakfast.

Rip thought of the way the commander had turned red with rage at that
crack about his face, and he resolved, _He may eat me for breakfast, but
I'll be a very tough mouthful!_



CHAPTER THREE

Capture and Drive!


Commander O'Brine had not exaggerated. The residue of carbon and thorium
on the blast tube walls was stubborn, dirty, and penetrating. It was
caked on in a solid sheet, but when scraped, it broke up into fine
powder.

The Planeteers wore coveralls, gloves, and face masks with respirators,
but that didn't prevent the stuff from sifting through onto their bodies.
Rip, who directed the work and kept track of the radiation with a
gamma-beta ion chamber and an alpha proportional counter, knew they would
have to undergo personal decontamination.

He took a reading on the ion chamber. Only a few milliroentgens of beta
and gamma radiation. That was the dangerous kind, because both beta
particles and gamma rays could penetrate clothing and skin. But the
Planeteers wouldn't get enough of a dose to do any harm at all. The
alpha count was high, but so long as they didn't breathe any of the dust,
it was not dangerous.

The _Scorpius_ had six tubes. Rip divided the Planeteers into two squads,
one under his direction and one under Koa's. Each tube took a couple of
hours' hard work. Several times during the cleaning, the men would leave
the tube and go into the main mixing chamber while the tube was blasted
with live steam to throw the stuff they had scraped off out into space.

Each squad was on its last tube when a spaceman arrived. He saluted Rip.
"Sir, the safety officer says to secure the tubes."

That could mean only one thing: deceleration. Rip rounded up his men.
"We're finished. The safety officer passed the word to secure the tubes,
which means we're going to decelerate." He smiled grimly. "You all know
they gave us this job just out of pure love for the Planeteers. So
remember it when you go through the control room to the decontamination
chamber."

The Planeteers nodded enthusiastically.

Rip led the way from the mixing chamber, through the heavy safety door,
and into the engine control room. His entrance was met with poorly
concealed grins by the spacemen.

Halfway across the room, Rip turned suddenly and bumped into Sergeant
Major Koa. Koa fell to the deck, arms flailing for balance--but flailing
against his protective clothing. The other Planeteers rushed to pick him
up, and somehow all their hands beat against each other.

The protective clothing was saturated with fine dust. It rose from them
in a choking cloud and was picked up and dispersed by the ventilating
system. It was contaminated dust. The automatic radiation safety
equipment filled the ship with an earsplitting buzz of warning. Spacemen
clapped emergency respirators to their faces and spoke unkindly of Rip's
Planeteers in the saltiest space language possible.

Rip and his men picked up Koa and continued the march to the
decontamination room, grinning under their respirators at the
consternation around them. There was no danger to the spacemen, since
they had clapped on respirators the moment the warning sounded. But even
a little contamination meant the whole ship had to be gone over with
instruments, and the ventilating system would have to be cleaned.

The deputy commander met Rip at the door of the radiation room. Above the
respirator, his face looked furious.

"Lieutenant," he bellowed, "haven't you any more sense than to bring
contaminated clothing into the engine control room?"

Rip was sorry the deputy commander couldn't see him grinning under his
respirator. He said innocently, "No, sir, I haven't any more sense than
that."

The deputy grated, "I'll have you up before the Discipline Board for
this."

Rip was enjoying himself thoroughly. "I don't think so, sir. The
regulations are very clear. They say, 'It is the responsibility of the
safety officer to insure compliance with all safety regulations by both
complete instructions to personnel and personal supervision.' Your safety
officer didn't instruct us, and he didn't supervise us. You'd better run
_him_ up before the Board."

The deputy commander made harsh sounds into his respirator. Rip had him,
and he knew it. "He thought even a stupid Planeteer had sense enough to
obey radiation safety rules," he yelled.

"He was wrong," Rip said gently. Then, just to make himself perfectly
clear, he added, "Commander O'Brine was within his rights when he made us
rake radiation. But he forgot one thing. Planeteers know the regulations,
too. Excuse me, sir. I have to get my men decontaminated."

Inside the decontamination chamber, the Planeteers took off their masks
and faced Rip with admiring grins. For a moment he grinned back, feeling
pretty good. He had held his own with the spacemen, and he sensed that
his men liked him.

"All right," he said briskly. "Strip down and get into the showers."

In a few moments they were all standing under the chemically treated
water, washing off the contaminated dust. Rip paid special attention to
his hair, because that was where the dust was most likely to stick. He
had it well lathered when the water suddenly cut off. At the same moment,
the cruiser shuddered slightly as control blasts stopped its spinning and
left them all weightless. Rip saw instantly what had happened. He called,
"All right, men. Down on the floor."

The Planeteers instantly slid to the shower deck. In a few seconds the
pressure of deceleration pushed at them.

"I like spacemen," Rip said wryly. "They wait until just the right moment
before they cut the water and decelerate. Now we're stuck in our birthday
suits until we land--wherever that may be."

Corporal Nels Pederson spoke up in a soft Stockholm accent. "Never mind,
sir. We'll get back at them. We always do!"

While the _Scorpius_ decelerated and started maneuvering for a landing,
Rip did some rapid calculations. He knew the acceleration and
deceleration rates of cruisers of this class, measured in terms of time,
and part of his daily routine on the space platform had been to examine
the daily astroplot, which gave the positions of all planets and other
large bodies within the solar system.

There was only one possible destination: Mars.

Rip's pulse quickened. He had always wanted to visit the red planet. Of
course, he had seen all the films, audio-mags, and books concerning it,
and he had tried to see the weekly spacecast. He had a good idea of what
the planet was like, but reading or viewing was not like actually landing
and taking a look for himself.

Of course, they would land at Marsport. It was the only landing area
equipped to handle nuclear drive cruisers.

The cruiser landed and deceleration cut to zero. At the same moment the
water came on.

Rip hurriedly finished cleaning up, dressed, then took his radiation
instruments and carefully monitored his men as they came from the
shower. Private Dowst had to go back for another try at getting his hair
clean, but the rest were all right. Rip handed his instruments to Koa.
"You monitor Dowst when he finishes. I want to see what's happening."

He hurried from the chamber and made his way down the corridors toward
the engine control room. There was a good possibility he might get a call
from O'Brine, with instructions to take his men off the ship. He might
finally learn what he was assigned to do!

As he reached the engine control room, Commander O'Brine was giving
instructions to his spacemen on the stowage of equipment that evidently
was expected aboard. Rip felt a twinge of disappointment. If the
_Scorpius_ had landed to take on supplies of some kind, his assignment
was probably not on Mars.

He started to approach the commander with a question about his orders,
then thought better of it. He stood quietly near the control panel and
watched.

The air lock hissed, then slid open. A Martian stood in the entryway, a
case on his shoulder. Rip watched him with interest. He had seen Martians
before, on the space platform, but he had never gotten used to them. They
were human, still....

He tried to figure out, as he had before, what it was that made them
strange. It wasn't the blue-whiteness of their skins nor the very large,
expressionless eyes. It was something about their bodies. He studied the
Martian's figure carefully. He was slightly taller and more slender than
the average earthman, but his chest measurements would be about the same.
Nor were his legs very much longer.

Suddenly Rip thought he had it. The Martian's legs and arms joined his
torso at a slightly different angle, giving him an angular look. That was
what made him look like a caricature of a human, although he was human,
of course--as human as any of them.

Rip saw that other Martians were in the air lock, all carrying cases of
various sizes and shapes. They came through into the control room and put
them down, then turned without a word and hurried back into the lock.
They were all breathing heavily, Rip noticed. Of course! The artificial
atmosphere inside the spaceship must seem very heavy and moist to them,
after the thin, dry air of Mars.

The lock worked, and the Martians were replaced by others. They, too,
deposited their cases. But these cases were bigger and heavier. It took
four Martians to carry one, which meant they weighed close to half a ton
each. The Martians could carry more than double an earthman's capacity.

When the lock worked next time, a Planeteer captain came in. He breathed
the heavy air appreciatively, fingering the oxygen mask he had to wear
outside. He saluted Commander O'Brine and reported, "This is all, sir. We
filled the order exactly as Terra sent it. Is there anything else you
need?"

O'Brine turned to his deputy. "Find out," he ordered. "This is our last
chance. We have plenty of basic supplies, but we may be short of
audio-mags and other things for the men." He turned his back on the
Planeteer captain and walked away.

The captain grinned at O'Brine's retreating back, then walked over to
Rip. They shook hands.

"I'm Southwick, SOS Two. Canadian."

Rip introduced himself and said he was an American. He added, "And aside
from my men, you're the first human being I've seen since we made space."

Southwick chuckled. "Trouble with the spacemen? Well, you're not the
first."

Talking about assignments wasn't considered good practice, but Rip was
burning with curiosity. "You don't by chance know what my assignment
is, do you?"

The captain's eyebrows went up. "Don't you?"

Rip shook his head. "O'Brine hasn't told me."

"I don't know a thing," Southwick said. "We got instructions to pack up a
pretty strange assortment of supplies for the _Scorpius_, and that's all
I know. The order was in special cipher, though, so we're all wondering
about it."

The deputy commander returned, reported to O'Brine, then walked up to Rip
and Southwick. "Nothing else needed," he said curtly. "We'll get off at
once."

Southwick nodded, shook hands with Rip, and said in a voice the deputy
could hear, "Don't let these spacemen bother you. Trouble with them is
they all wanted to be Planeteers and couldn't pass the intelligence
tests." He winked, then hurried to the air lock.

Spacemen worked quickly to clear the deck of the new supplies, stowing
them in a nearby workroom. Within five minutes the engine control room
was clear. The safety officer signaled, and the radiation warning
sounded. Taking off!

Rip hurried to the squad room and climbed into an acceleration chair. The
other Planeteers were already in the room, most of them in their bunks.
Koa slid into the chair beside him. "Find out anything, sir?"

"Nothing useful. A bunch of equipment came aboard, but it was in plain
crates. I couldn't tell what it was."

Acceleration pressed them against the chairs. Rip sighed, picked up an
audio-circuit set, and put it over his ears. Might as well listen to what
the circuit had to offer. There was nothing else to do. Music was
playing, and it was the kind he liked. He settled back to relax and
listen.

_Brennschluss_ came some time later. It woke Rip up from a sound sleep.
He blinked, glancing at his chronometer. Great Cosmos! With that length
of acceleration they must be high-vacking for Jupiter! He waited until
the ship went into the gravity spin, then got out of his chair and
stretched. He was hungry. Koa was still sleeping. He decided not to wake
him. The sergeant major would see that the men ate when they wanted to.

In the messroom only one table was occupied--by Commander O'Brine.

Rip gave him a civil hello and started to sit alone at another table. To
his surprise, O'Brine beckoned to him.

"Sit down," the spaceman invited gruffly.

Rip did and wondered what was coming next.

"We'll start to decelerate in about ten minutes," O'Brine said. "Eat
while you can." He signaled, and a spaceman brought Rip the day's ration
in an individual plastic carton with thermo-lining. The Planeteer opened
it and found a block of mixed vegetables, a slab of space meat, and two
units of biscuit. He wrinkled his nose. Space meat he didn't mind. It was
chewy but tasty. The mixed vegetable ration was chosen for its food value
and not for taste. A good mouthful of Earth grass would be a lot more
palatable. He sliced off pieces of the warm stuff and chewed
thoughtfully, watching O'Brine's face for a clue as to why the commander
had invited him to sit down.

It wasn't long in coming. "Your orders are the strangest things I've ever
read," O'Brine stated. "Do you know where we're going?"

Rip figured quickly. They had accelerated for six and a half hours. Now,
ten minutes after _Brennschluss_, they were going to start deceleration.
That meant they had really high-vacked it to get somewhere in a hurry. He
calculated swiftly.

"I don't know exactly," he admitted. "But from the ship's actions, I'd
say we were aiming for the far side of the asteroid belt. Anyway, we'll
fall short of Jupiter."

There was a glimmer of respect in O'Brine's glance. "That's right. Know
anything about asteroids, Foster?"

Rip considered. He knew what he had been taught in astronomy and
astrogation. Between Mars and Jupiter lay a broad belt in which the
asteroids swung. They ranged from Ceres, a tiny world only 480 miles in
diameter, down to chunks of rock the size of a house. No accurate count
of asteroids--or minor planets, as they were called--had been made, but
the observatory on Mars had charted the orbits of thousands. A few were
more than a mile in diameter, but most were great boulders of irregular
shape, from a few feet to several hundred feet at their greatest
dimension.

"I know the usual stuff about them," he told O'Brine. "I haven't any
special knowledge."

O'Brine blinked. "Then why did they assign you? What's your specialty?"

"Astrophysics."

"That might explain it. Second specialty?"

"Astrogation." He couldn't resist adding, "That's more advanced than the
simple space navigation you use, Commander."

O'Brine started to retort, then apparently thought better of it. "I hope
you'll be able to carry out your orders, Lieutenant," he said stiffly.
"I hope, but not much. I don't think you can."

Rip asked, "What are my orders, sir?"

O'Brine waved in the general direction of the wall. "Out there somewhere
in the asteroid belt, Foster, there is a little chunk of matter about one
thousand yards in diameter. A very minor planet. We know its approximate
coordinates as of two days ago, but we don't know much else. It happens
to be a very important minor planet."

Rip waited, intent on the commander's words.

"It's important," O'Brine continued, "because it happens to be pure
thorium."

Rip gasped. Thorium! The rare, radioactive element just below uranium in
the periodic table of the elements, the element used to power this very
ship! "What a find!" he said in a hushed voice. No wonder the job was
Federation priority A, with Space Council security! "What do I do about
it?" he asked.

O'Brine grinned. "Ride it," he said. "Your orders say you're to capture
this asteroid, blast it out of its orbit, and drive it back to Earth!"



CHAPTER FOUR

Find the Needle!


Rip walked into the squad room with a copy of the orders in his hand.
After one look at his face, the Planeteers clustered around him. Santos
woke those who were sleeping, while Rip waited.

"We have our orders, men," he announced. Suddenly he laughed. He couldn't
help it. At first he had been completely overcome by the responsibility
and the magnitude of the job, but now he was getting used to the idea,
and he could see the adventure in it. Ten wild Planeteers riding an
asteroid! Sunny space, what a great big thermonuclear stunt!

Koa remarked, "It must be good. The lieutenant is getting a real atomic
charge out of it."

"Sit down," Rip ordered. "You'd better, because you might fall over when
you hear this. Listen, men. Two days ago the freighter _Altair_ passed
through the asteroid belt on a run from Jupiter to Mars." He sat down,
too, because deceleration was starting. As his men looked at each other
in surprise at the quickness of it, he continued, "The old bucket found
something we need--an asteroid of pure thorium."

The enlisted Planeteers knew as well as he what that meant. There were
whistles of astonishment. Koa slapped his thigh. "By Gemini! What do we
do about it, sir?"

"We capture it," Rip said. "We blast it loose from its orbit and ride it
back to Earth."

He sat back and watched their reactions. At first they were stunned.
Trudeau, the Frenchman, muttered to himself in French. Dominico, the
Italian, held up his hands and exclaimed, "Santa Maria!"

Kemp, one of the American privates, asked, "How do we do it, sir?"

Rip grinned. "That's a good question. I don't know."

That stopped them. They stared at him. He added quickly, "Supplies came
aboard at Marsport. We'll get the clue when we open them. Headquarters
must have known the method when they assigned us and ordered the
equipment they thought we'd need."

Koa stood up. He was the only one who could have moved upright against
the terrific deceleration. He walked to a rack at one side of the squad
room and took down a copy of _The Space Navigator_. Then, resuming his
seat, he looked questioningly at Rip. "Anything else, sir? I thought I'd
read what there is about asteroids."

"Go ahead," Rip agreed. He sat back as Koa began to recite what data
there was, but he didn't listen. His mind was going ten astro-units
a second. He thought he knew why he had been chosen for the job. Word of
the priceless asteroid must have reached headquarters only a short time
before he was scheduled to leave the space platform. He could imagine the
speed with which the specialists at Terra base had acted. They had sent
orders instantly to the fastest cruiser in the area, the _Scorpius_, to
stand by for further instructions. Then their personnel machines must
have whirred rapidly, electronic brains searching for the nearest
available Planeteer officer with an astrophysics specialty and
astrogation training.

He could imagine the reaction when the machine turned up the name of a
brand-new lieutenant. But the choice was logical enough. He knew that
most, if not all, of the Planeteer astrophysicists were in either high
or low space on special work. Chances were there was no astrophysicist
nearer than Ganymede. So the choice had fallen to him.

He had a mental image of the Terra base scientists feeding data into the
electronic brain, taking the results, and writing fast orders for the men
and supplies needed. Work at the Planeteer base had probably been
finished within an hour of the time word was received.

When they opened the cases brought aboard by the Martians, he would see
that the method of blasting the asteroid into a course for Earth was all
figured out for him.

Rip was anxious to get at those cases. Not until he saw the method of
operation could he begin to figure his course. But there was no
possibility of getting at the stuff until _Brennschluss_. He put the
problem out of his mind and concentrated on what his men were saying.

"... and he slugged into that asteroid going close to seven AU's," Santos
was saying. The corporal shrugged expressively.

Rip recognized the story. It was about a supply ship, a chemical drive
rocket job, that had blasted into an asteroid a few years before.

Private Dowst shrugged, too. "Too bad. High vack was waiting for him.
Nothing you can do when Old Man Nothing wants you. Not a thing in space!"

Rip listened, interested. This was the talk of old space hands, who
had given the high vacuum of empty space a personality, calling it
"high vack," or "Old Man Nothing." With understandable fatalism, they
believed--or said they believed--that when high vacuum really wanted
you, there was nothing you could do.

Rip had come across an interesting bit of word knowledge. Spacemen and
Planeteers alike had a way of using the phrase "by Gemini!" Gemini, of
course, was the constellation of the Twins, Castor and Pollux. Both were
useful stars for astrogation. The Roman horse soldiers of ancient history
had sworn "by Gemini," or "by the Twins." The Romans believed the stars
were the famous Greek warriors Castor and Pollux, placed in the heavens
after their deaths. In later years, the phrase degenerated to the simple
"by jiminy," and its meaning had been lost. Now, although few spacemen
knew the history of the phrase, they were using it again, correctly.

Other space talk grew out of space itself, not out of history. For
instance, the worst thing that could happen to a man was to have his
helmet broken. Let the transparent globe be shattered, and the results
were both quick and final. Hence the oft heard threat, "I'll bust your
bubble."

Speaking of bubbles ... Rip realized suddenly that he and his men would
have to live in bubbles and space suits while on the asteroid. None of
the minor planets were big enough to have an atmosphere or much gravity.

If only he could get a look into those cases! But the ship was still
decelerating, and he would have to wait. He put his head against the
chair rest and settled down to wait as patiently as he could.

_Brennschluss_ was a long time coming. When the deceleration finally
stopped, Rip didn't wait for gravity. He hauled himself out of the chair
and the squad room and went down the corridor hand over hand. He headed
straight for where the supplies were stacked, his Planeteers close behind
him.

Commander O'Brine arrived at the same time. "We're starting to scan for
the asteroid," he greeted Rip. "May be some time before we find it."

"Where are we, sir?" Rip asked.

"Just above the asteroid belt near the outer edge. We're beyond the
position where the asteroid was sighted, moving along what the _Altair_
figured as its orbit. I'm not stretching space, Foster, when I tell you
we're hunting for a needle in a junk pile. This part of space is filled
with more objects than you would imagine, and they all register on the
rad screens."

"We'll find it," Rip said confidently.

O'Brine nodded. "Yes. But it probably will take some hunting. Meanwhile,
let's get at those cases. The supply clerk is on his way."

The supply clerk arrived, issued tools to the Planeteers, then opened a
plastic case attached to one of the boxes and produced lists. As the
Planeteers opened and unpacked the crates, Rip and O'Brine inspected, and
the clerk checked off the items.

The first case produced a complete chemical cutting unit, with an
assortment of cutting tips and adapters. Rip looked around for the gas
cylinders and saw none. "Something's wrong," he objected. "Where's the
fuel supply for the torch?"

The supply clerk inspected the lists, shuffled papers, and found the
answer.

"The following," he read, "are to be supplied from the _Scorpius_
complement. One landing boat, large, model twenty-eight. Eight each,
oxygen cutting unit gas bottles. Four each, chemical cutting unit fuel
tanks."

"That's that," Rip said, relieved. Apparently he was supposed to do a lot
of cutting on the asteroid, probably of the thorium itself. The hot flame
of the torch could melt any known substance. The torch itself could melt
in unskilled hands.

The next case yielded a set of astrogation instruments, carefully cradled
in a soft, rubbery plastic. Rip left them in the case and put them to one
side. As he did so, Sergeant Major Koa let out a whistle of surprise.

"Lieutenant, look at this!"

Corporal Santos exclaimed, "Well, stonker me for a stupid space squid! Do
they expect us to find any people on this asteroid?"

The object was a portable rocket launcher designed to fire light attack
rockets. It was a standard item of fighting equipment for Planeteers.

"I recognize the shape of those cases over there, now," Koa said. "Ten
racks of rockets for the launcher, one rack to a case."

Rip scratched his head. He was as puzzled as Santos. Why supply fighting
equipment for a crew on an asteroid that couldn't possibly have any
living thing on it?

He left the puzzle for the future and called for more cases. The next
two yielded projectile-type handguns for ten men, with ammunition, and
standard Planeteer space knives. The space knives had hidden blades,
which were driven forth violently when the operator pushed a thumb lever,
releasing the gas in a cartridge contained in the handle. The blades
snapped forth with enough force to break a bubble or to cut through a
space suit. They were designed for the sole purpose of space hand-to-hand
combat.

The Planeteers looked at each other. What were they up against, that such
equipment was needed on a barren asteroid?

Private Dowst opened a box that contained a complete tool kit, the tools
designed to be handled by men in space suits. Yards of wire, for several
purposes, were wound on reels. Two hand-driven dynamos capable of
developing great power were included.

Corporal Pederson found a small case which contained books, the latest
astronomical data sheets, and a space computer and scratch board. These
were obviously for Rip's personal use. He examined them. There were all
the references he would need for computing orbit, speed, and just about
anything else that might be required. He had to admire the thoroughness
of whoever had written the order. The unknown Planeteer had assumed that
the space cruiser would not have all the astrophysics references
necessary and had included a copy of each.

Several large cases remained. Koa ripped the side from one and let out an
exclamation. Rip hurried over and looked in. His stomach did a quick
orbital reverse. Great Cosmos! The thing was an atomic bomb!

Commander O'Brine leaned over his shoulder and peered at the lettering on
the cylinder: EQUIVALENT TEN KT.

In other words, the explosion the harmless-looking cylinder could produce
was equivalent to ten thousand tons of TNT, a chemical explosive no
longer in actual use but still used for comparison.

Rip asked huskily, "Any more of those things?" The importance of the job
was becoming increasingly clear to him. Nuclear explosives were not used
without good reason. The fissionable material was too valuable for other
purposes.

The sides came off the remaining cases. Some of them held fat tubes of
conventional rocket fuel in solid form, the igniters carefully packed
separately.

There were three other atomic bombs, making four in all. There were two
bombs each of five KT and ten KT.

Commander O'Brine looked at the amazing assortment of stuff. "Does that
check, clerk?"

The spaceman nodded. "Yes, sir. I found another notation that says food
supplies and personal equipment to be supplied by the _Scorpius_."

"Well, vack me for a Venusian rabbit!" O'Brine muttered. He tugged at his
ear. "You could dump me on that asteroid with this assortment of junk,
and I'd spend the rest of my life there. I don't see how you can use this
stuff to move an asteroid!"

"Maybe that's why the Federation sent Planeteers," Rip said--and was
sorry the moment the words were out.

O'Brine's jaw muscles bulged, but he held his temper. "I'm going to
pretend I didn't hear that, Foster. We have to get along until the
asteroid is safely in an orbit around Earth. After that, I'm going to
take a great deal of pleasure in feeding you to the space fish, piece
by piece."

It was Rip's turn to get red. "I'm sorry, Commander. Accept my
apologies." He certainly had a lot to learn about space etiquette. There
was a time for spacemen and Planeteers to fight each other and a time for
them to cooperate.

"I'm sure you'll be able to figure out what to do with this stuff,"
O'Brine said. "If you need help, let me know."

And Rip knew his apology was accepted.

The deputy commander arrived, drew O'Brine aside, and whispered in his
ear. The commander let out an exclamation and started out of the room. At
the door he turned. "Better come along, Foster."

Rip followed as the commander led the way to his own quarters. At the
door two space officers were waiting, their faces grave.

O'Brine motioned them to chairs. "All right, let's have it."

The senior space officer held out a sheet of flimsy. It was pale blue,
the color used for highly confidential documents. "Sir, this came in
Space Council special cipher."

"Read it aloud," O'Brine ordered.

"Yes, sir. It's addressed to you, this ship. From Planeteer Intelligence,
Marsport. 'Consops cruiser departed general direction your area. Agents
report crew _Altair_ may have leaked data re asteroid. Take appropriate
action.' It's signed 'Williams, SOS, Commanding.'"

Rip saw the meaning of the message instantly. The Consolidation of
People's Governments, of Earth, traditional enemies and rivals of the
Federation of Free Governments, needed radioactive minerals as badly as,
or worse than, the Federation. In space it was first come, first take.
They had to find the asteroid quickly. It was to prevent Consops from
knowing of the asteroid that security measures had been taken. They
hadn't worked, because of loose space chatter at Marsport.

O'Brine issued quick orders. "Now, get this. We have to work fast.
Accelerate fifty percent, same course. I want two men on each screen.
If anything of the right size shows up, decelerate until we can get mass
and albedo measurements. Snap to it."

The space officers started out, but O'Brine stopped them. "Use one
long-range screen for scanning high space toward Mars. Let me know
the minute you get a blip, because it probably will be that Consops
cruiser. Have the missile ports cleared for action."

Rip's eyes opened. Clear the missile ports? That meant getting the
cruiser in fighting shape, ready for instant action. "You wouldn't fire
on that Consops cruiser, would you, sir?"

O'Brine gave him a grim smile. "Certainly not, Foster. It's against
orders to start anything with Consops cruisers. You know why. The
situation is so tense that a fight between two spaceships might plunge
Earth into war." His smile got even grimmer. "But you never know. The
Consops ship might fire first. Or an accident might happen."

The commander leaned forward. "We'll find that asteroid for you, Mr.
Planeteer. We'll put you on it and see you on your way. Then we'll ride
space along with you, and if any Consops thieves try to take over and
collect that thorium for themselves, they'll find Kevin O'Brine waiting.
That's a promise."

Rip felt a lot better. He sat back in his chair and regarded the
commander with mixed respect and something else. Against his will, he
was beginning to like the man. No doubt of it, the _Scorpius_ was well
named. And the sting in the scorpion's tail was O'Brine himself.



CHAPTER FIVE

The Gray World


Rip rejoined his Planeteers in the supply room and motioned for them
to gather around him. "I know why Terra base sent us the fighting
equipment," he announced. "They were afraid word of this thorium asteroid
would leak out to Consops--and it has. A Connie cruiser blasted off from
Marsport and it's headed this way."

He watched the faces of his men carefully, to see how they would take the
news. They merely looked at each other and shrugged. Conflict with
Consops was nothing new to them.

"The freighter that found the asteroid landed at Marsport, didn't it?"
Koa asked. Getting a nod from Rip, he went on, "Then I know what probably
happened. The two things spacemen can't do are breathe high vack and keep
their mouths shut. Some of the crew blabbed about the asteroid, probably
at the Space Club. That's where they hang out. The Connies hang out
there, too. Result, we get a Connie cruiser after the asteroid."

"You hit it," Rip acknowledged.

Corporal Santos shrugged. "If the Connies try to take the asteroid away,
they'll have a real warm time. We have ten racks of rockets, twenty-four
to a rack. That's a lot of snapper-boats we can pick off if they try to
make a landing."

The Planeteers stopped talking as the voice horn sounded. "Get it! We are
going into no-weight. Prepare to stay in no-weight indefinitely. Rotation
stops in two minutes."

Rip realized why the order was given. The _Scorpius_ could not maneuver
while in a gravity spin, and O'Brine wanted to be free to take action if
necessary.

The voice horn came on again. "Now get it again. The ship may maneuver
suddenly. Prepare for acceleration or deceleration without warning. One
minute to no-weight."

Rip gave quick orders. "Get lines around the equipment and prepare to
haul it. I'll get landing boats assigned, and we can load. Then prepare
space packs. Lay out suits and bubbles. We want to be ready to go the
moment we get the word."

Lines were taken from a locker and secured to the equipment. As the
Planeteers worked, the ship's spinning slowed and stopped. They were
in no-weight. Rip grabbed for a hand cord that hung from the wall and
hauled himself out into the engine control room. The deputy commander was
at his post, waiting tensely for orders. Rip thrust against a bulkhead
with one foot and floated to his side. "I need two landing boats, sir,"
he requested. "One stays on the asteroid with us."

"Take numbers five and six. I'll assign a pilot to bring number five back
to the ship after you've landed."

"Thank you." Rip would have been surprised at the deputy's quick assent
if Commander O'Brine hadn't shown him that the spacemen were ready to do
anything possible to aid the Planeteers. He went back to the supply room
and told Koa which boats were to be used, instructed him to get the
supplies aboard, then made his way to Commander O'Brine's office.

O'Brine was not in. Rip searched and found him in the astroplot room,
watching a 'scope. Green streaks called "blips" marked the panel, each
one indicating an asteroid.

"All too small," O'Brine said. "We've only seen two large ones, and they
were too large."

"Space is certainly full of junk," Rip commented. "At least this corner
of it is pretty full."

A junior space officer overheard him. "This is nothing. We're on the edge
of the asteroid belt. Closer to the middle, there's so much stuff a ship
has to crawl through it."

Rip wandered over to the main control desk. A senior space officer was
seated before a simple panel on which there were only a dozen small
levers, a visiphone, and a radar screen. The screen was circular, with
numbers around the rim like those on an Earth clock. In the center of the
screen was a tiny circle. The central circle represented the _Scorpius_.
The rest of the screen was the area dead ahead. Rip watched and saw
several blips on it that indicated asteroids. They were all small. He
watched, interested, as the _Scorpius_ overtook them. Once, according to
the screen, the cruiser passed under an asteroid, with a clearance of
only a few hundred feet.

"You didn't miss that one by much," Rip told the space officer.

"Don't have to miss by much," he retorted. "A few feet are as good as a
mile in space. Our blast might kick them around a little, and maybe
there's a little mutual mass attraction, but we don't worry about it."

He pointed to a blip that was just swimming into view, a sharp green
point against the screen. "We do have to worry about that one." He
selected a lever and pulled it toward him.

Rip felt sudden weight against his feet. The green point on the screen
moved downward, below center. The feeling of weight ceased. He knew what
had happened, of course. Around the hull of the ship, set in evenly
spaced lines, were a series of blast holes through which steam was fired.
The steam was produced instantly by running water through the heat coils
of the nuclear engine. By using groups or combinations of steam tubes,
the control officer could move the ship in any direction, set it rolling,
spin it end over end, or whirl it in an eccentric pattern.

"How do you decide which tubes to use?" Rip asked.

"Depends on what's happening. If we were ducking missiles from an enemy,
I'd get orders from the commander. But to duck asteroids, there's no
problem. I go over them by firing the steam tubes along the bottom of the
ship. That way, you feel the acceleration on your feet. If I fired the
top tubes, the ship would drop out from under those who were standing.
They'd all end up on the overhead."

Rip watched for a while longer, then wandered back to Commander O'Brine.
He was getting anxious. At first the task of capturing an asteroid and
moving it back to Earth had been rather unreal, like some of the problems
he had worked out while training on the space platform. Now he was no
longer calm about it. He had faith in the Terra base Planeteer
specialists, but they couldn't figure out everything for him. Most of the
problems of getting the asteroid back to Earth would have to be solved by
Lt. Richard Ingalls Peter Foster.

A junior space officer suddenly called, "Sir, I have a reading at
two-seventy degrees, twenty-three degrees eight minutes high."

Commander O'Brine jumped up so fast that the action shot him to the
ceiling. He kicked down again and leaned over the officer's 'scope.
Rip got there by pulling himself right across the top of the chart table.

The green point of light on the 'scope was bigger than any other he had
seen.

"It's about the right size," O'Brine said. There was excitement in his
voice. "Correct course. Let's take a look at it."

All hands gripped something with which to steady themselves as the
cruiser spun swiftly onto the new course. The control officer called,
"I have it centered, sir. We'll reach it in about an hour at this speed."

"Jack it up," O'Brine ordered. "Heave some neutrons into it. Double
speed, then decelerate to reach it in thirty minutes."

The control officer issued orders to the engine control room. In a moment
acceleration plucked at them. O'Brine motioned to Rip. "Come on, Foster.
Let's see what Analysis makes of this rock."

Rip followed the commander to the deck below, where the technical
analysts were located. His heart was pounding a little faster than usual,
and not from acceleration, either. He found himself wetting his lips
frequently and thought, _Get hold of it, boy. You've got nothing to worry
about but high vacuum._

He didn't really believe it. There would be plenty to worry about. Like
detonating nuclear bombs and trying to figure their blast reaction. Like
figuring out the course that would take them closest to the sun without
pulling them into it. Like a thousand things--all of them up to him.

The chief analyst greeted them. "We got the orders to change course,
Commander. That gave us the location of the asteroid. We're already
working on it."

"Anything yet?"

"No, sir. We'll have the albedo measurement in a few minutes. It'll take
longer to figure the mass."

The asteroid's efficiency in reflecting sunlight was its albedo. The
efficiency depended on the material of which it was made. The albedo of
pure metallic thorium was known. If the asteroid's albedo matched it,
that would be one piece of evidence.

In the same way, the mass of thorium was known. The measurements of the
asteroid were being taken. They would be compared with a chunk of thorium
of the same size. If it worked out, that would be evidence enough.

Commander O'Brine motioned to chairs. "Might as well sit down while we're
waiting, Foster." He took one of the chairs and looked closely at Rip.
Suddenly he grinned. "I thought Planeteers never got nervous."

"Who's nervous?" Rip retorted, then answered his own question truthfully.
"I am. You're right, sir. The closer we get, the more scared I get."

"That's a good sign," O'Brine replied. "It means you'll be careful. Got
any real doubts about the job?"

Rip thought it over and didn't think so. "Not any real ones. I think we
can do it. But I'm nervous just the same. Great Cosmos, Commander! This
is my first assignment, and they give me a whole world to myself and tell
me to bring it home. Maybe it isn't a very big world, but that doesn't
change things much."

O'Brine chuckled. "I never expected to get an admission like that from a
Planeteer."

"And I," Rip retorted, "never expected to make one like that to a
spaceman."

The chief analyst returned, a sheet of computations in his hand. "Report,
sir. The albedo measurement is correct. This may be it."

"How long before we get the measurements and comparisons?"

"Ten minutes, perhaps."

Rip spoke up. "Sir, there's some data I'll need."

"What, Lieutenant?" The analyst got out a notebook.

"I'll need all possible data on the asteroid's speed, orbit, and physical
measurements. I will have to figure a new orbit and what it will take to
blast the mass into it."

"We'll get those. The orbit will not be exact, of course. We have only
two reference points. But I think we'll come pretty close."

O'Brine nodded. "Do what you can, Chief. And when Foster gets down to
doing his calculations, have your men run them through the electronic
computer for him."

Rip thanked them both, then stood up. "Sir, I'm going back to my men. I
want to be sure everything is ready. If there's a Connie cruiser headed
this way, we don't want to lose any time."

"Good idea. I think we'll dump you on the asteroid, Foster, and then
blast off. Not too far, of course. Just enough to lead the Connie away
from you if its screen picks us up."

That sounded good to Rip. "We'll be ready when you are, sir."

The chief analyst took less than the estimated ten minutes for his next
set of figures. Commander O'Brine called personally while Rip was still
searching for the right landing-boat ports. The voice horn bellowed, "Get
it, Lieutenant Foster! The mass measurements are correct. This is your
asteroid. Estimated twelve minutes before we reach it. Your data will be
ready by the time you get back here. Show an exhaust!"

Rip found Koa and the men and asked the sergeant major for a report.

"We're ready, sir," Koa told him. "We can get out in three minutes. It
will take us that long to get into space gear. Your stuff is laid out,
sir."

"Get me the books and charts from the supplies," Rip directed. "Have
Santos take them to the chief analyst. I'm going back and figure our
course. No use doing it the hard way on the asteroid, when I can do it in
a few minutes here with the ship's computer."

He turned and hurried back, hauling himself along by handholds. The ship
had stopped acceleration and was at no-weight again. As he neared the
analysis section, it went into deceleration, but the pressure was not too
bad. He made his way against it easily.

The chief analyst was waiting for him. "We have everything you need,
Lieutenant, except the orbital stuff. We'll do the best we can on that
and have an estimate in a few minutes. Meanwhile you can mark up your
figures. Incidentally, what power are you going to use to move the
asteroid?"

"Nuclear explosions," Rip said, and saw the chief's eyes pop. He added,
"With conventional chemical fuel for corrections."

He felt rising excitement. The whole ship seemed to have come to life.
There was excited tension in the computer room when he went in with the
chief. Spacemen, all mathematicians, were waiting for him. As the chief
led him to a table, they gathered around him.

Rip took command. "Here's what we're after. I need to plot an orbit that
will get us out of the asteroid belt without collisions, take us as close
to the sun as possible without having it capture us, and land us in space
about ten thousand miles from Earth. From then on I'll throw the asteroid
into a braking ellipse around the earth, and I'll be able to make any
small corrections necessary."

He spread out a solar system chart and marked in the positions of the
planets as of that moment, using the daily almanac. Then he put down the
position of the asteroid, taking it from the paper the chief analyst
handed him.

"Will you make assignments, Chief?"

The chief shook his head. "Make them yourself, Lieutenant. We're at your
service."

Rip felt a little ashamed of some of the unkind things he had said about
spacemen. "Thank you." He pointed to a spaceman. "Will you calculate the
inertia of the asteroid, please?" The spaceman hurried off. "First thing
to do is plot the orbit as though there were no other bodies in the
system," Rip said. "Where's Santos?"

"Here, sir." The corporal had come in unnoticed with Rip's reference
books.

Rip had plotted orbits before, but never one for actual use. His palms
were wet as he laid it out, using prepared tables. When he had finished
he pointed to a spaceman. "That's it. Will you translate it into analogue
figures for the computer, please?" He assigned to others the task of
figuring out the effect Mercury, the sun, and Earth would have on the
orbit, using an assumed speed for the asteroid.

To the chief analyst he gave the job of putting all the data together in
proper form for feeding to the electronic brain.

It would have taken all spacemen present about ten days to complete the
job by regular methods, but the electronic computer produced the answer
in three minutes.

"Thanks a million, Chief," Rip said. "I'll be calling on you again before
this is over." He tucked the sheets into his pocket.

"Anytime, Lieutenant. We'll keep rechecking the figures as we go along.
If there are any corrections, we'll send them to you. That will give
you a check on your own figures."

"Don't worry," Rip assured him, "we're going to have plenty of
corrections before we're through."

Deceleration had been dropping steadily. It ceased altogether, leaving
them weightless. O'Brine's voice came over the speaker. "Get it! Valve
crews take stations at landing boats five and six. The Planeteers will
depart in five minutes. Lieutenant Foster will report to central control
if he cannot be ready in that time."

Santos grinned at Rip. "Here we go, Lieutenant."

Rip's heart would have dropped into his shoes if there had been any
gravity. Only a little excitement showed on his face, though. He waved
his thanks at the analysts and grinned back at Santos.

"Show an exhaust, Corporal. High vack is waiting!"



CHAPTER SIX

Rip's Planet


Rip rechecked his space suit before putting on his helmet. The air seal
was intact, and his heating and ventilating units worked. He slapped his
knee pouches to make sure the space knife was handy to his left hand, the
pistol to his right.

Koa was already fully dressed. He handed Rip the shoulder case that
contained the plotting board. Santos had taken charge of Rip's
astrogation instruments.

A spaceman was waiting with Rip's bubble. At a nod, the spaceman slipped
it on his head. Rip reached up and gave it a quarter turn. The locking
mechanism clamped into place. He turned his belt ventilator control on
full, and the space suit puffed out. When it was fully inflated, he
watched the pressure gauge. It was steady. No leaks in suit or helmet.
He let the pressure go down to normal.

Koa's voice buzzed in his ears. "Hear me, sir?"

Rip adjusted the volume of his communicator and replied, "I hear you. Am
I clear?"

"Yessir. All men dressed and ready."

Rip made a final check. He counted his men, then personally inspected
their suits. The boats were next. They were typical landing craft,
shaped like rectangular boxes. There was no need for streamlining in the
vacuum of space. They were not pressurized. Only men in space suits rode
in the ungainly boxes.

He checked all blast tubes to make sure they were clear. There were small
single tubes on each side of the craft. A clogged one could explode and
blow the boat up.

Koa, he knew, had checked everything, but the final responsibility was
his. In space, no officer took anyone's word for anything that might mean
lives. Each checked every detail personally.

Rip looked around and saw the Planeteers watching him. There was approval
on the faces behind the clear helmets, and he knew they were satisfied
with his thoroughness.

At last, certain that everything was in good order, he said quietly,
"Pilots, man your boats."

Dowst got into one and a spaceman into the other. Dowst's boat would stay
with them on the asteroid. The spaceman would bring the other back to the
ship.

Commander O'Brine stepped through the valve into the boat lock. A
spaceman handed him a hand communicator. He spoke into it. Rip couldn't
have heard him through the helmet otherwise. "All set, Foster?"

"Ready, sir."

"Good. The long-range screen picked up a blip a few minutes ago. It's
probably that Connie cruiser."

Rip swallowed. The Planeteers froze, waiting for the commander's next
words.

"Our screens are a little better than theirs, so there's a slim chance
they haven't picked us up yet. We'll drop you and get out of here. But
don't worry. We have your orbit fixed, and we'll find you when the
screens are clear."

"Suppose they find us while you're gone?" Rip said.

"It's a chance," O'Brine admitted. "You'll have to take spaceman's
luck on that one. But we won't be far away. We'll duck behind Vesta,
or another of the big asteroids, and hide so their screens won't pick
up our motion. Every now and then we'll sneak out for a look, if the
screen seems clear. If those high-vack vermin do find you, get on the
landing-boat radio and yell for help. We'll come blasting."

He waved a hand, thumb and forefinger held together in the ancient symbol
for "everything right," then ordered, "Get flaming." He stepped through
the valve.

"Clear the lock," Rip ordered. "Open outer valve when ready."

He took a quick, final look around. The pilots were in the boats. His
Planeteers were standing by, safety lines already attached to the boats
and their belts. He moved into position and snapped his own line to a
ring on Dowst's boat. The spacemen vanished through the valve, and the
massive door slid closed. The overhead lights flicked out. Rip now
snapped on his belt light, and the others followed suit.

In front of the boxlike landing boats a great door slid open, and air
from the lock rushed out. Rip knew it was only imagination, but he felt
as though all the heat from his suit was radiating into space, chilling
him to near absolute zero. Beyond the lights from their belts, he saw
stars and recognized the constellation for which the space cruiser was
named. A superstitious spaceman would have taken that as a good sign.
Rip admitted that it was nice to see.

"Float 'em," he ordered.

The Planeteers gripped handholds at the entrance with one hand and
launching rails on the boats with the other, then heaved. The boats
slid into space. As the safety lines tightened, the Planeteers were
pulled after the boat.

Rip left his feet with a little spring and shot through the door.
Directly below him, the asteroid gleamed darkly in the light of the tiny
sun. His first reaction was "Great Cosmos! What a little chunk of rock!"
But that was because he was used to looking from the space platform at
the great curve of Terra or at the big ball of the moon. Actually the
asteroid was fair-sized, when compared with most of its kind.

The Planeteers hauled themselves into the boats by their safety lines.
Rip waited until all were in, then pulled himself along his own line
to the black square of the door. Koa was waiting to give him a hand into
the craft.

The Planeteers were standing, except for Dowst. Rip had never seen an
old-type railroad, or he might have likened the landing boat to a
railroad boxcar. It was about the same size and shape, but had huge
"windows" on both sides and in front of the pilot--windows that were
not enclosed. The space-suited men needed no protection.

"Blast," Rip ordered.

A pulse of fire spurted from the top of each boat, driving them bottom
first toward the asteroid.

"Land at will," Rip said.

The asteroid loomed large as he looked through an opening. It was rocky,
but there were plenty of smooth places.

Dowst picked one. He was an expert pilot, and Rip watched him with
pleasure. The exhaust from the top lessened, and fire spurted soundlessly
from the bottom. Dowst balanced the opposite thrusts of the top and
bottom blasts with the delicacy of a woman threading a needle. In a few
moments the boat was hovering a foot above the asteroid. Dowst cut the
exhausts, and Rip stepped out onto the tiny planet.

The Planeteers knew what to do. Corporal Pederson produced hardened steel
spikes with ring tops. Private Trudeau had a sledge. Driving the first
spike would be the hardest, because the action of swinging the hammer
would propel the Planeteer like a rocket exhaust. In space, the law that
every action has an equal and opposite reaction had to be remembered
every moment.

Rip watched, interested in how his man would tackle the problem. He
didn't know the answer himself, because he had never driven a spike
on an airless world with almost no gravity, and no one had ever mentioned
it to him.

Pederson searched the gray metal with his torch and found a slender spur
of thorium, perhaps two feet high, a short distance from the boat.
"Here's a hold," he said. "Come on, Frenchy. You too, Bradshaw."

Trudeau, carrying the sledge, walked up to the spur of rock and stood
with his heels against it. Pederson sat down on the ground with his legs
on either side of the spur. He stretched, hooking his heels around
Trudeau's ankles, anchoring him. With his gloves, he grabbed the seat of
the Frenchman's space suit.

Bradshaw took a spike and held it against the gray metal ground. The
Frenchman swung, his hammer noiseless as it drove the tough spike. A
few inches into the metal was enough. Bradshaw took a wrench from his
belt, put it on the head of the spike, and turned it. Below the surface,
teeth on the spike bit into the metal. It would hold.

The rest was easy. The spike was used to anchor Trudeau while he drove
another, at his longest reach. Then the second spike became his anchor,
and so on, until enough spikes had been set to lace the boat down against
any sudden shock.

The boat piloted by the spaceman was tied to the one that would remain,
and the Planeteers floated its supplies through a window. It took only a
few moments, with Planeteers forming a chain from inside the boat to a
spot a little distance away. The crates weighed almost nothing, but still
retained their mass. Once their inertia was overcome, they moved from one
man to the next like ungainly balloons.

"All clear, sir," Koa called.

Rip stepped inside and made a quick inspection. The box was empty except
for the spaceman pilot. He put a hand on the pilot's shoulder. "On your
way, Rocky. Thanks."

"You're welcome, sir." The pilot added, "Watch out for high vack."

Rip and Koa stepped out and walked a little distance away. Santos and
Pederson cast the landing boat adrift and shoved it away from the
anchored boat. In a moment fire spurted from the bottom tube, spreading
over the dull metal and licking at the feet of the Planeteers.

Rip watched the boat rise upward to the great, sleek, dark bulk of the
_Scorpius_. The landing boat maneuvered into the air lock with brief
flares from its exhausts. In a few moments the sparkling blast of
auxiliary rocket tubes moved the spaceship away. O'Brine was putting a
little distance between his ship and the asteroid before turning on the
nuclear drive. The ship decreased in size until Rip saw it only as a
dark, oval silhouette against the Milky Way. Then the exhaust of the
nuclear drive grew into a mighty column of glowing blue, and the ship
flamed into space.

For a moment Rip had a wild impulse to yell for the ship to come back.
He had been in vacuum before, but only as a cadet, with an officer in
charge. Now, suddenly, he was the one responsible. The job was his. He
stiffened. Planeteer officers didn't worry about things like that.
He forced his mind to the job at hand.

The next step was to establish a base. The base would have to be on the
dark side of the asteroid, once it was in its new orbit. That meant a
temporary base now and a better one later, when they had blasted the
little planet into its new course. He estimated roughly the approximate
positions where he would place his charges, using the sun and the star
Canopus as visual guides.

"This will do for a temporary base," he announced. "Rig the boat
compartment. While two of you are doing that, you others break out the
rocket launcher and rocket racks and assemble the cutting torch. Koa will
make assignments."

While the sergeant major translated Rip's general instructions into
specific orders for each man, the young lieutenant walked to the edge
of the sun belt. There was no atmosphere, so the edge was a sharp line
between dark and light. There wasn't much light, either. They were too
far from the sun for that. But as they neared the sun, the darkness would
be their protection. They would get so close to Sol that the metal on the
sun side would get soft as butter.

He bent close to the uneven surface. It was clean metal, not oxidized
at all. The thorium had never been exposed to oxygen. Here and there,
pyramids of metal thrust up from the asteroid, sometimes singly,
sometimes in clusters. They were metal crystal formations. He guessed
that once, long ages ago, the asteroid had been a part of something much
bigger, perhaps a planet. One theory said the asteroids were formed when
a planet exploded. This asteroid might have been a pocket of pure thorium
in the planet.

There would be plenty to do in a short while, but meanwhile he enjoyed
the sensation of being on a tiny world in space with only a handful of
Planeteers for company. He smiled. "King Foster," he said to himself.
"Monarch of a thorium space speck." It was a rather nice feeling, even
though he laughed at himself for thinking it. Since he was in command of
the detachment, he could in all truth say that this was his own personal
planet. It would be a good bit of space humor to spring on the folks back
on Terra.

"Yep, once I was boss of a whole world. Made myself king. Emperor of all
the metal molecules and king of the thorium spurs. And my subjects obeyed
my every command." He added, "Thanks to Planeteer discipline. The
detachment commander is boss."

He reminded himself that he had better stop gathering space dust and
start acting like a detachment commander. He walked back to the landing
boat, stepping with care. With such low gravity, a false step could send
him high above the asteroid. Of course, that would not be dangerous,
since space suits were equipped with six small compressed-air bottles for
emergency propulsion. But it would be embarrassing.

Inside the boat, Dowst and Nunez were setting up the compartment.
Sections of the rear wall swung out and locked into place against
airtight seals, forming a box at the rear end of the boat. Equipment
sealed in the stern, next to the rocket tube, supplied light, heat, and
air. It was a simple but necessary arrangement. Without it, the
Planeteers could not have eaten.

There was no air lock for the compartment. The half of the detachment not
on duty would walk in, seal it up, turn on the equipment, wait until the
gauges registered sufficient air and heat, and then remove their space
suits. When it was time to leave, they would don suits, open the door,
and walk out, and the next shift would enter and repeat the process.
Earlier models had permanent compartments, but they took up too much room
in craft designed for carrying as many men and as much equipment as
possible. They were strictly work boats, and hard experience had dictated
the best design.

The rocket launcher was already set up near the boat. It was a simple
affair, with three adjustable legs bolted to ground spikes. The legs
held a movable cradle in which the rocket racks were placed. High-geared
hand controls enabled the gunner to swing the cradle at high speed in
any direction except straight down. A simple, illuminated optical sight
was all the gunner needed. Since there were neither gravity nor
atmosphere in space, the missiles flashed out in a straight line,
continuing on into infinity if they missed their targets. Proximity fuses
made this a remote possibility. If the rocket got anywhere near the
target, the shell would explode.

Rip found his astrogation instruments set carefully to one side. He
removed the data sheets from his case and examined them. Now came the
work of finding the spots in which to place his atomic charges. Since the
computer aboard ship had done all the mathematics necessary, he needed
only to take sights to determine the precise positions.

He took a transit-like instrument from the case, pulled out the legs of
its self-contained tripod, then carried it to a spot near where he had
estimated the first charge would be placed. The instrument was equipped
with three movable rings to be set for the celestial equator, for the
zero meridian, and for the right ascension of any convenient star. Using
a regular level would have been much simpler. The instrument had one, but
with so little gravity to activate it, the thing was useless.

The sights were specially designed for use in space, and his bubble was
no obstacle in taking observations. He merely put the clear plastic
against the curved sight and looked into it much as he would have looked
through a telescope on Earth.

As he did so, a hint of pale pink light caught the corner of his eye. He
backed away from the instrument and turned his head quickly, looking at
the colorimeter-type radiation detector at the side of his helmet. It was
glowing.

An icy chill sent a shiver through him. Great, gorgeous galaxies! He had
forgotten ... had Koa and the others? He turned so fast that he lost his
balance and floated above the surface like a captive balloon. Santos, who
had been standing nearby to help if requested, hooked a toe on the ground
spike, caught him, and set him upright on the ground again.

"Get me the radiation detection instruments," he ordered.

Koa sensed the urgency in his voice and got the instruments himself. Rip
switched them on and read the illuminated dial on the alpha counter.
Plenty high, as was natural. But no danger there--alpha particles
couldn't penetrate the space suits. Then, his hand clammy inside the
space glove, he switched on the other meter. The gamma count was far
below the alpha, but there were too many of the rays around for comfort.
Inside the helmet his face turned pale.

There was no immediate danger. It would take many days to build up a dose
of gamma that could hurt them. But gamma was not the only radiation. They
were in space, fully exposed to equally dangerous cosmic radiation.

The Planeteers had gathered while he read the instruments. Now they stood
watching him.

They knew the significance of what he had found.

"I ought to be busted to recruit," he told them. "I knew this asteroid
was thorium and that thorium is radioactive. If I had used my head, I
would have added nuclite shielding to the list of supplies the _Scorpius_
provided. We could have had enough of it to protect us while around our
base, even if we couldn't be protected while working on the charges. That
would at least have kept our dosage down enough for safety."

"No one else thought of it, either, sir," Koa reminded him.

"It was my job to think of it, and I didn't. So I've put us in a time
squeeze. If the _Scorpius_ gets back soon, we can get the shielding
before our radiation dosage has built up very high. If the ship doesn't
come back, the dosage will mount."

He looked at them grimly. "It won't kill us, and it won't even make us
very sick. I'll have the ship take us off before we build up that much
dosage."

Santos started. "But, sir! That means--"

"I know what it means," Rip stated bitterly. "It means the ship has got
to return in time to give us some nuclite shielding, or we'll be the
laughingstock of the Special Order Squadrons--the detachment that started
a job the spacemen had to finish!"



CHAPTER SEVEN

Earthbound!


There was something else that Rip didn't add, although he knew the
Planeteers would realize it in a few minutes. Probably some of them
already had thought of it.

To move the asteroid into a new orbit, they were going to fire nuclear
bombs. Most of the highly radioactive fission products would be blown
into space, but some would be drawn back by the asteroid's slight
gravity. The craters would be highly radioactive, and some radioactive
debris was certain to be scattered around, too. Every particle would add
to the problem.

"Is there anything we can do, sir?" Koa asked.

Rip shook his head inside the transparent bubble. "If you have a good
luck charm in your pocket, you might talk to it. That's about all."

Nuclear physics had been part of his training. He read the gamma meter
again and did some quick calculations. They would be exposed for the
entire trip, at a daily dosage of--

Koa interrupted his train of thought. Evidently the sergeant major had
been doing some calculations of his own. "How long will we be on this
rock, sir? You've never told us just how long the trip will take."

Rip said quietly, "With luck, it will take us a little more than three
weeks."

He could see their faces faintly in the dim sunlight. They were shocked.
Spaceships blasted through space between the inner planets in a matter
of hours. The nuclear drive cruisers, which could approach almost half
the speed of light, had brought even distant Pluto within easy reach.
The inner planets could be covered in a matter of minutes on a straight
speed run, although to take off from one and land on the other meant
considerable time used in acceleration and deceleration.

The Planeteers were used to such speed. Hearing that it would take over
three weeks to reach Earth had jarred them.

"This piece of metal isn't a spaceship," Rip reminded them. "At the
moment, our speed around the sun is just slightly more than ten miles a
second. If we just shifted orbits and kept the same speed, it would take
us months to reach Terra. But we'll use one bomb for retrothrust, then
fire two to increase speed. The estimate is that we'll push up to about
forty miles a second."

Koa spoke up. "That's not bad when you think that Mercury is the fastest
planet, and it only makes about thirty miles a second."

"Right," Rip agreed. "After the asteroid is kicked out of orbit, it will
fall toward the sun. At our closest approach to the sun, we'll have
enough velocity to carry us past safely. Then we'll lose speed constantly
until we come into Earth's gravitational field and have to brake."

It was just space luck that Terra was on the other side of the sun from
the asteroid's present position. By the time they approached, it would
be in a good place, just far enough from the line to the sun to avoid
changing course. Of course, Rip's planned orbit was not aiming the
asteroid at Earth, but at where Earth would be at the end of the trip.

"That means more than three weeks of radiation, then," Corporal Santos
observed. "Can we take it, sir?"

Rip shrugged, but the gesture couldn't be seen inside his space suit. "At
the rate we're getting radiation now, plus what I estimate we'll get from
the nuclear explosions, we'll get the maximum safety limit in just three
weeks. That leaves us no margin, even if we risk getting radiation
sickness. So we have to get shielding pretty soon. If we do, we can last
the trip."

Private Dominico saluted and moved forward. "Sir, may I ask a question?"

Rip turned to face the Planeteer, still worrying over the problem. He
nodded and said, "What is it, Dominico?"

"Sir, I think we can't worry too much about this radiation, eh? You will
think of some way to take care of it. What I want to ask, sir, is when do
we let go the bombs? I do not know much about radiation, but I can set
those bombs like you want them."

Rip was touched by the Planeteer's faith in his ability to solve the
radiation problem. That was why being an officer in the Special Order
Squadrons was so challenging. The men knew the kind of training their
officers had, and they expected them to come up with technical solutions
as the situation required.

"You'll have a chance to set the bombs in just a short while," he said
crisply. "Let's get busy. Koa, load all bombs but one ten KT on the
landing boat. Stake the rest of the equipment down. While you're doing
that, I'll find the spots where we plant the charges. I'll need two men
now and more later."

He went back to his instrument, putting the radiation problem out of his
mind--a rather hard thing to do with the colorimeter glowing pink next to
his shoulder. Koa detailed men to load the nuclear bombs into the landing
craft, left Pederson to supervise, and then brought Santos with him to
help Rip.

"The bombs are being put on the boat, sir," Koa reported.

"Fine. There isn't too much chance of the blasts setting them off, but
we'll take no chances at all. Koa, I'm going to shoot a line straight out
toward Alpha Centauri. You walk that way and turn on your belt light.
I'll tell you which way to move."

He adjusted his sighting rings while the sergeant major glided away.
Moving around on a no-weight world was more like skating than walking. A
regular walk would have lifted Koa into space with every step. Of course,
the asteroid had some gravity, but so little that it hardly mattered.

Rip centered the top of the instrument's vertical hairline on Alpha
Centauri, then waited until Koa was almost out of sight over the
asteroid's horizon, which was only a few hundred yards away.

He turned up the volume on his helmet communicator. "Koa, move about ten
feet to your left."

Koa did so. Rip sighted past the vertical hairline at the belt light.
"That's a little too far. Take a small step to the right. That's
good ... just a few inches more ... hold it. You're right in position.
Stand where you are."

"Yessir."

Rip turned to Santos. "Stand here, Corporal. Take a sight at Koa to get
your bearings, then hold position."

Santos did so. Now the two lights gave Rip one of the lines he needed. He
called for two more men, and Trudeau and Nunez joined him. "Follow me,"
he directed.

Rip picked up the instrument and carried it to a point ninety degrees
from the line represented by Koa and Santos. He put the instrument down
and zeroed it on Messier 44, the Beehive star cluster in the
constellation Cancer. For the second sighting star he chose Beta Pyxis
as being closest to the line he wanted, made the slight adjustments
necessary to set the line of sight, since Pyxis wasn't exactly on it,
then directed Trudeau into position as he had Koa. Nunez took position
behind the instrument, and Rip had his cross fix.

He called for Dowst, then carried the instrument to the center of the
cross formed by the four men. Using the instrument, he rechecked the
lines from the center out. They were within a hair or two of being
exactly on, and a slight error wouldn't hurt, anyway. He knew he would
have to correct with rocket blasts once the asteroid was in the new
orbit.

"X marks the spot," he told Dowst. He put his toe on the place where the
crosslines met.

Dowst used a spike to make an X in the metal ground.

"All set," Rip announced. "You four men can move now. Let's have the
cutting equipment over here, Koa."

The Planeteers were all waiting for instructions now. In a few moments
the equipment was ready, fuel and oxygen bottles attached.

"Who's the champion torchman?" Rip asked.

Koa replied, "Kemp is, sir."

Kemp, one of the two American privates, took the torch and waited for
orders. "We need a hole six feet across and twenty feet deep," Rip told
him. "Go to it."

"How about direction, sir?" Kemp asked.

"Straight down. We'll take a bearing on an overhead star when you're in a
few feet."

Dowst inscribed a circle around the X he had made and stood back. Kemp
pushed the striker button and the torch flared. "Watch your eyes," he
warned. The Planeteers reached for belt controls and turned the rheostats
that darkened the clear bubbles electronically. Kemp adjusted his flame
until it was blue-white, a knife of fire brighter by far than the light
of the sun at this distance.

Koa stepped behind Kemp and leaned against his back, because the flame of
the torch was like an exhaust, driving Kemp backward. Kemp bent down, and
the torch sliced into the metal of the asteroid like a hot knife into
ice. The metal splintered a little as the heat raised it instantly from
almost absolute zero to many thousands of degrees.

When the circle was completed, Kemp adjusted his torch again, and the
flame lengthened. He moved inside the circle and cut at an angle toward
the perimeter. His control was quick and certain. In a moment he stood
aside, and Koa lifted out a perfect ring of thorium. It varied from a
knife edge on the inner side to eighteen inches on the outer side.

In the middle of the circle there was now a cone of metal. Kemp cut
around it, the torch angling toward the center. A piece shaped like
two cones set base to base came free. Since the metal cooled in the
bitter chill of space almost as fast as Kemp could cut it, there was no
heat to worry about.

Alternately cutting from the outside and the center of the hole, Kemp
worked his way downward until his head was below ground level. Rip
called a halt. Kemp gave a little jump and floated straight upward. Koa
caught him and swung him to one side. Rip stepped into the hole, and
Santos gave him a slight push to send him to the bottom. Rip knelt and
sighted upward. Kemp had done a good job. The star Rip had chosen as a
guide was straight overhead.

He bounced out of the hole, and, as Koa caught him, he told Kemp to go
ahead. "Dominico, here's your chance. Get tools and wire. Find a timer
and connect up the ten-kiloton bomb. Nunez, bring it here while Dominico
gets what he needs."

Kemp was burning his way into the asteroid at a good rate. Every few
moments he pushed another circle or spindle of thorium out of the hole.
Rip directed some of the men to carry them away, to the other side of the
asteroid. He didn't want chunks of thorium flying around from the blast.

The sergeant major had a sudden thought. He cut off his communicator,
motioned to Rip to do the same, then put his helmet against Rip's for
direct communication. He didn't want the others to hear what he had to
say. His voice came like a roar from the bottom of a well. "Lieutenant,
do you suppose there's any chance the blast might break up the asteroid?
Maybe split it in two?"

The same thought had occurred to Rip on the _Scorpius_. His calculations
had showed that the metal would do little more than compress, except
where it melted from the terrific heat of the bomb. That would be only
in and around the shaft. He was sure the men at Terra base had figured
it out before they decided that A-bombs would be necessary to throw the
asteroid into a new orbit. He wasn't worried. Cracks in the asteroid
would be dangerous, but he hadn't seen any.

"This rock will take more nuclear blasts than we have," he assured Koa.
He turned his communicator back on and went to the edge of the hole for
a look at Kemp's progress. He was far down now. Pederson was holding one
end of a measuring tape. The other end was fastened to Kemp's shoulder
strap.

The Swedish corporal showed Rip that he had only about eight feet of tape
left. Kemp was almost down. Rip called, "Kemp, when you reach bottom, cut
toward the center. Leave an inverted cone."

"Got it, sir. Be up in two more cuts."

Dominico had connected cable to the bomb terminals and was attaching a
timer to the other end. Without the wooden case, the bomb was like a fat,
oversized can. It had been shipped without a combat casing.

"Koa, make a final check. You can untie the landing boat, except for one
line. We'll be taking off in a few minutes."

"Right, sir." Koa glided toward the landing boat, which was moored out of
sight beyond the horizon.

It was nearly time. Rip had a moment's misgiving. Had his figures or his
sightings been off? His scalp prickled at the thought. But the ship's
computer had done the work, and it was not capable of making a mistake.

Kemp tossed up the last section of thorium and then came out of the hole
himself, carrying his torch.

Rip inspected the hole, saw with satisfaction that it was in almost
perfect alignment, and ordered the bomb placed. He bent over the edge
of the hole and watched Trudeau pay out wire while Dominico pushed the
bomb to the bottom. The Italian made a last-minute check, then called
to Rip. "Ready, sir."

Rip dropped into the hole and inspected the connections himself, then
personally pulled the safety lever. The bomb was armed. When the timer
acted, it would go off.

Back at ground level, he turned up his communicator. "Koa, is everything
ready at the boat?"

"Ready, sir."

The Planeteers had already carried away the torch and its fuel and oxygen
supplies. The area was clear of pieces of thorium.

Rip announced, "We're setting the explosion for ten minutes." He leaned
over the timer, which rested near the lip of the hole, took the dial
control in his glove, and turned it to position ten. He held it long
enough to glance at his chronometer and say, "Starting now!" Then he
let it go.

Wasting no time, but not hurrying, he and Dominico returned to the
landing boat. The Planeteers were already aboard, except for Koa, who
stood by to cast off the remaining tie line. Rip stepped inside and
counted the men. All present. He ordered, "Cast off." As Koa did so
and stepped aboard, Rip added, "Pilot, take off. Straight up."

The landing boat rose from the asteroid. Rip counted the men again, just
to be sure. The boat seemed a little crowded, but that was because the
rear compartment took up quite a bit of room.

Rip watched his chronometer. They had plenty of time. When the boat
reached a point about ten miles above the asteroid, he ordered, "Stern
tube." The boat moved at an angle. He let it go until a sight at the
stars showed they were in about the right position, ninety degrees from
the line of blast and where they would be behind the asteroid as it moved
toward the new course.

He looked at his chronometer again. "Two minutes. Line up at the side if
you want to watch, but darken your helmets to full protection. This thing
will light up like nothing you've ever seen before."

It was a good thing space cruisers depended on their radar and not on
sight, he thought. Usually spacemen opened up visual ports only when
landing or taking a star sight for an astroplot. The clear plastic of the
domes had to be shielded from chance meteors. Besides, radar screens were
more dependable than eyes, even though they could pick up only solid
objects. If the Consops cruiser happened to be searching visually, it
would see this blast. But the chance had to be taken. It wasn't really
much of a chance.

"One minute," he said. He faced the asteroid, then darkened his helmet,
counting to himself.

The minute ticked off rapidly, though his count was a little slow. When
he reached five, brilliant, incandescent light lit up the interior of the
boat. Rip saw it even though his helmet was dark. The light faded slowly,
and as it did, he gradually put his helmet back on full transparent.

A mighty column of fire now reached out from the asteroid into space. Rip
held his breath until he saw that the little planet was sheering off its
course under the great blast. Then he sighed with relief. All was well so
far.

Someone muttered, "By Gemini! I'm glad we're out here instead of down
there!"

The column of fire lengthened, thinned out, grew fainter, until there was
only a glow behind the asteroid. Rip took his astrogation instruments and
made a number of sights. They looked good. The first blast had worked
about as predicted, although he wouldn't be able to tell how much
correction was needed until he had taken star sights over a period of
five or six days.

"Let's go home," he ordered.

Back on the asteroid, a pit that glowed with radioactivity marked the
site of the first blast. Rip ordered the men to stay as far from it as
possible, to avoid increasing their radiation doses. He plotted the lines
for the second blast, found the spot, and put Kemp back to work on a new
hole.

Two hours later the second blast threw fire into space. In another three
hours, with the asteroid now speeding on its new course, Rip set off the
explosion that blasted straight back and gave extra speed.

Three radioactive craters marked the asteroid. Rip checked the radiation
level and didn't like it a bit. He decided to set up the landing boat and
their supplies as far away from the craters as possible, which was on the
sun side. They could move to the dark side as they approached the orbit
of Earth. By then the radioactivity from the blasts would have died down
considerably.

He was selecting the location for a base when Dowst suddenly called,
"Lieutenant Foster!"

There was urgency in the Planeteer's voice. "What is it, Dowst?"

"Sir, take a look, about two degrees south of Rigel!"

Rip found the constellation Orion and looked at bright Rigel. For a
moment he saw nothing; then, south of the star, he saw a thin, orange
line.

Nuclear drive cruisers didn't have exhausts of that color, and there was
only one rocket-drive ship around, so far as they knew.

Rip said softly, "Let's get our house in order, gang. Looks as if we're
going to get a visit from the Connies!"



CHAPTER EIGHT

Duck--or Die!


Sergeant Major Koa's great frame loomed in front of Rip. "Think they've
spotted us, sir?"

Rip hated to say it. "Probably. Koa, can you estimate from the exhaust
how far away they are?"

"Not very well, Lieutenant. From the position of the streak, I'd say
they're decelerating."

The Planeteers looked at Rip. He was in command, and they expected him to
do something about the situation. Rip didn't know what to do. The rocket
launcher, their only weapon, wasn't designed for fighting spaceships. It
was useful against snapper-boats and people, but firing at a cruiser
would be like sending mosquitoes to fight elephants.

He sized up their position. For one thing, they were right out in the
open, exposed to anything the Connie cruiser might throw at them. If they
could get under cover, there might be a chance. At least it would take
the Connies a while to find them.

For a moment he thought of hurrying into the landing boat and sending out
a call for help to the _Scorpius_, but he thought better of it. They
weren't certain that Connie had spotted them. He would wait until there
was no doubt. Meanwhile, they had to find cover.

His searching eyes fell on the cutting torch. If they could use that to
cut themselves right into the asteroid.... Suddenly he knew how it could
be done. On the sun side he remembered a series of high-piled, giant
crystals of thorium. They could cut into the side of one of those. And
with Kemp's skill, they might be able to do it in time.

He called, "Kemp, Koa, bring the torch and fuel and follow me."

In his haste he took a misstep and flew headlong a few feet above the
metal surface. Koa, gliding along behind him, turned him upright again.
He saw that the sergeant major was grinning. Rip grinned back. It was the
second time he had lost his footing.

They reached the peaks of thorium, and Rip looked them over. The tallest
was perhaps forty feet high. It was roughly pyramidal, with a base about
sixty feet thick. It would do.

"Kemp." The private hurried to his side. "Take the torch and make us a
cave. Make it big enough for the entire crew and the equipment."

Kemp was a good Planeteer. He didn't stop to ask questions. He said,
"I'll make a small entrance and open the cave out inside." He picked up
the torch and got busy.

Rip smiled. The Planeteer was right. He should have thought of it
himself, but it was good to see increasing proof that his men were smart
as well as tough and disciplined.

"Bring up all supplies," he told Koa. "Move the boat over here, too. We
won't be able to bury that, but we want it close by." He had an idea for
their boat. It was able to maneuver infinitely faster than the big
cruiser. They could put the supplies in the cave, then take to the boat,
depending on its ability to turn quickly and on Dowst's skill at piloting
to play hide and seek. Dowst certainly could keep the asteroid between
them and the cruiser.

The plan would fail when the cruiser sent a landing party. They would
certainly come in snapper-boats, and those deadly little fighting craft
could blast rings around the landing boat. The snapper-boats had gotten
their name because fast acceleration and quick changes of position could
snap a man right out of his seat if he forgot to buckle his harness
tightly.

The solution would be to keep the landing boat close to the asteroid. At
the first sign of a landing party, they would take to the cave, using the
rocket launcher as a defense.

The supplies began to arrive. The Planeteers towed them two crates at a
time in a steady line of hurrying men.

Kemp's torch sent an incandescent knife three feet into the metal at each
cut. He was rapidly slicing out a cave. He cut the metal out in great
triangular bars, angling the torch from first one side, then the other.

Koa came and stood beside Rip. "I haven't seen the Connie's exhaust for a
while, sir. They've probably stopped decelerating. We can't see them at
all."

"Meaning what?" Rip asked. He thought he knew, but he wanted Koa's
opinion.

"They're in free fall now, sir. That could mean they're just hunting in
the area. Or it could mean that they've stopped somewhere close by. They
could be looking us over right now, for all we know."

Rip surveyed the stars. "If that's so, they're not too close, Koa.
Otherwise they'd block out a patch of stars."

"Well, sir--" Koa hesitated. "I mean, if you were looking over this
asteroid, and you weren't sure whether the enemy had it or not, how close
would you get?"

"Probably about one AU," Rip said jokingly. That was one astronomical
unit, equal to about ninety-three million miles, the distance from Earth
to the sun.

"That's a safe distance, sir," Koa agreed with a grin.

"But let's suppose the Connie isn't as timid as I am," Rip went on. "He
might be only a few miles out. The question is, would he wait to get
closer before launching his snapper-boats?"

The tall officer answered frankly, "I've never been in a space grab like
this. I don't know the answer."

"We'll soon know," Rip replied grimly. A thought had just struck him. The
_Scorpius_ had trouble finding the asteroid because it was just one of
many sailing along through the belt. But now the asteroid was the only
one traveling _across_ the belt. It would make an outstanding blip on any
radarscope. It wasn't possible that the Connie cruiser had missed the
blip and its significance.

"The Connie may be looking us over," Rip added, "but I'll tell you one
thing. He knows we've taken the asteroid."

Koa looked wistfully at the atomic bomb which remained. "If we had a way
to throw that thing at them...."

"But we haven't. And the thing wouldn't explode, anyway. We don't have
the outside casing with an exploder mechanism, so it has to be turned on
electrically." Rip could see no way to use the atomic bomb against the
Connies. It was too big for use against a landing party. Besides, it
would put the Planeteers themselves in danger.

"Ever have trouble with the Connies before?" he asked Koa.

"More'n once, sir. Sometimes it seems like I'll never get a job where
I don't have to fight Connies."

Rip was trained in science and Planeteer techniques, and he didn't
pretend to know the ins and outs of interplanetary politics. Just the
same, he couldn't help wondering about the strange relationship between
the Consolidation of People's Governments and the Federation of Free
Nations.

Connies and Feds, mostly Planeteers but sometimes spacemen, were
constantly skirmishing. They fought over property, over control of
ports on distant planets and moons, and over space salvage. Often there
was bloodshed. Sometimes there were pitched battles between groups of
platoon size.

But at that point the struggle ended. The law of the Federation said that
no spaceship could fire on a Connie spaceship or on Connie land bases,
except with special permission of the Space Council. The theory was that
brief struggles between men, or even between small fighting craft like
the snapper-boats, was not war. But firing on a spaceship was considered
an act of war, and the first such act could mean the beginning of a war
throughout the entire solar system.

It made a sort of sense to Rip when he thought about it. Little fights
here and there were better than a full war among the planets.

Koa suddenly gripped his arm. "Sir! Look up!"

The short hairs on the back of Rip's neck prickled. Far above, blackness
in the shape of a spaceship blotted out stars. The Connie had arrived!

Rip ordered urgently, "Kemp! Stop cutting! The rest of you get the stuff
under cover. Ram it!" He hurried to lend a hand himself, hustling crates
into the cave.

Kemp had made astonishing progress. There was room for the crates, if
stacked properly, and for the men, besides. Rip supervised the stacking
and then the placement of the rocket launcher at the entrance.

"All hands inside the boat," he ordered. "Dowst, be ready to take off at
a moment's notice. You'll have to buck this box around as never before."
He explained to the pilot his plan to dodge, keeping the asteroid between
the boat and the cruiser.

"We'll make it, sir," Dowst said.

"I'm not worried," Rip replied--and wished it were true. He looked up at
the Connie again. It was getting larger. The cruiser was within a few
miles of the asteroid.

As Rip watched, fire spurted from the cruiser, and it moved with
gathering speed toward the asteroid's horizon. He watched the exhaust
trail, wondering why the Connie had blasted off.

"He has something up his sleeve," Koa muttered. "Wish we knew what."

"Let's take no chances," Rip stated. "Come on."

The men were already in the boat. He and Koa joined them. They stood at a
window, watching the Connie's trail.

The trail dwindled. Koa said, "Something's up!" Suddenly new fire shot
from one side of the cruiser, and it spun. Balancing fire came from the
other side, and for an instant the three exhausts formed a cross, with
the darkness of the Connie's hull in the center. Then they could see only
the exhausts from the sides. The stern flame was out of sight. "He's made
a full turn to come back this way," Rip stated tensely. "Dowst, get
ready."

The Connie was perhaps twenty miles away. It grew larger, and the side
jets winked out. A few seconds later, fire spurted from the nose.

Rip figured rapidly. The cruiser had gone far enough away to make a turn.
It had straightened out, heading right for them. Now the nose tube was
blasting, slowing the cruiser down.

He sighted, holding out one glove, and gauging the Connie's distance
above the horizon, and his heart speeded. The Connie was right on the
horizon!

"Ram it!" Rip called. "Around the asteroid. Quick!"

Acceleration jammed him back against his men as Dowst blasted. No sooner
had he recovered than acceleration in a different direction shoved him up
to the ceiling so hard that his bubble rang. He clawed his way to the
window as the Connie cruiser flashed by, bathing the asteroid in glowing
flame.

There was a chorus of gasps from the men as they saw the thing Rip had
realized a moment before. The Consops cruiser was playing it safe, using
its rocket exhaust as a great blowtorch to burn the surface of the
asteroid clean of any possible life!

The sheer inhumanity of the thing made Rip's stomach tighten into a knot.
No asking for surrender, no taking of prisoners, not even a clean fight.
The Connie was doing its arguing with fire, knowing that the exhaust
would char every man on the asteroid's surface.

The Planeteers watched as the Connie sped away, blasted with side jets,
and turned to come back. Dowst tensed over the controls, trying to
anticipate the next move. He delicately touched the firing levers,
letting out just enough flame to maneuver. He slid the craft across the
asteroid's surface to the side away from the Connie, going slowly enough
that they could watch the enemy's every move.

"Here he comes," Rip snapped, and braced for acceleration. The landing
craft shot to safety as the cruiser's nose jet flamed. Dowst was just in
time. Tiny sparks from the edge of the fiery column brushed past the
boat.

Rip realized that the Connie couldn't know the Federation men were in a
boat, dodging. The cruiser would make about two more runs, just enough to
allow for hitting every bit of the asteroid. Then it would assume that
anything on it was finished and send a landing party.

"He'll be back," he stated. "About twice more. Three at most." He
suddenly remembered the landing boat's radio. "Dowst, where is the radio
connection?"

The pilot handed him a wire with a jack plug on the end of it. Rip
plugged it into his belt. Now his voice would be heard on the _Scorpius_.

"Calling _Scorpius_! Calling _Scorpius_! Foster reporting. We are under
attack. Repeat, we are under attack. Over to you."

The answer rang in his helmet. "_Scorpius_ to Foster. Hold 'em,
Planeteers. We're on our way!"

"Here comes the Connie," Koa yelled.

Rip braced. The landing boat shot forward, then piled the Planeteers in a
heap on the bottom as Dowst accelerated upward.

There was a sudden wrenching crash that sent the Planeteers in a jumbled
mass into the front of the boat. It whirled crazily, then stopped.

Rip was not hurt. He shoved at someone whose bubble was in his stomach
and cleared the way. "Turn on belt lights," he called. "Quick!"

Lights flared on. He searched quickly, swinging his light. The Planeteers
were getting to their feet. His light focused on Private Bradshaw, and he
gasped.

Bradshaw's face was scarlet, and his skin was flecked with drops of
blood. His eyes were closed and bulging horribly.

Rip jumped forward, but Koa was even faster. The Hawaiian jerked a repair
strip from a belt pouch and slapped it on the crack in Bradshaw's bubble.
Rip wasted no time, either. By the time Koa had the strip in place he had
pulled the connection from his belt light. He ran the tips of the wires
over the edges of the strip. The current sealed the patch in place
instantly.

Koa grabbed the atmosphere control on Bradshaw's belt and turned it. The
suit puffed up. Rip watched the repair anxiously in the light from Koa's
belt. It held.

Rip reconnected his light as he asked swiftly, "Anyone else hurt? Answer
by name."

There were quick replies. No one else had been injured.

"Run for the cave," Rip commanded. "Follow Koa. Santos and Pederson, drag
Bradshaw."

The Englishman's voice sounded bubbly. "I can make it."

"Good for you!" Rip exclaimed. "Call if you need help."

Koa was already out of the craft and leading the way. Rip went out
through a window and saw the cause of the trouble. Dowst had been a
hair too close to the asteroid. A particularly high crystal of thorium
had snagged the landing craft.

Rip looked for the Connie and saw it make another turn. They had only a
moment or two before the next run. "Show an exhaust!" he called. The
Connie must have blasted the opposite side of the asteroid while they
were hung up.

The cave was a quarter of the asteroid away. Rip stayed in the rear,
watching for stragglers, but even Bradshaw was moving rapidly. Koa
reached the cave well ahead of the rest, reached for a rack of rockets,
and slapped it into the launcher.

Rip urged the men on. The Connie was squared off for another run.

They catapulted to safety as the cruiser flamed past, the exhaust
splashing over the metal and sending sparks into the cave.

Rip looked out. That, if he had guessed right, was the last run. He
watched the Connie's stern jet cut off, saw the nose exhaust as the
cruiser decelerated to a fast stop.

"Check your weapons," he ordered.

He pulled his pistol from his knee pocket and checked it carefully. There
was a clip in the magazine. Other clips were in his pocket. The clips
were loaded with high velocity shells that exploded on contact. One slug
could stop a Venusian _krel_, a mammoth beast that had been described as
a cross between a sea lion and a cactus plant.

His knife was in place in the other knee pocket.

The Connie cruiser decelerated, went into reverse, and came to a full
stop about a mile from the asteroid. The Planeteers saw fire in two
places along the hull, marking the exhausts of two small craft.

"Snapper-boats," Koa said tonelessly. "Five men in each, if those are the
regular Connie kind."

Rip made a quick decision. With only one launcher they couldn't guard the
whole asteroid. "We'll stay under cover, except for Santos and Pederson.
You two sneak out. Take advantage of every bit of cover you can find. I
don't want you spotted. When a boat lands, report its position. The
Connies operate on different communicator frequencies, so they won't
overhear. We'll let them think they've burned the asteroid clean."

He paused. "They'll search for a while. Then, when they're pretty well
satisfied that all is quiet, we'll show up." Rip grinned at his
Planeteers. "We can have a real, old-fashioned surprise party."

Koa slid the safety catch from his pistol. "With fireworks," he added.



CHAPTER NINE

Repel Invaders!


The snapper-boats came out of the darkness of space, leaving a glowing
trail of fire. They were not graceful. Rip could see no beauty in their
lines, but to his professional eye there was plenty of deadly efficiency.

The Connie fighting craft looked like three globes strung evenly on
a steel tube. The middle globe was larger than the end ones, and it
was transparent. From it projected the barrels of two kinds of
weapons--explosive and ultrasonic. Five men usually rode in the middle
ball. One piloted. The other four were gunners.

The end globes were pierced by five large holes. They were blast tubes
for the rocket exhaust. Unlike the landing boats, each tube did not have
its own fuel supply. One fuel tank served each globe. The pilot could
direct the exhaust through any tube or combination of tubes he wished, by
operating valves that either sealed or opened the vents. The system gave
high maneuverability to the boats. By playing on the controls with the
skill of an organist, the pilot could shift direction with dazzling
speed.

Snapper-boats used by the Federation operated on the same principle, but
they were of American design, and they showed the Americans' love of
clean lines. Federation fighter craft were slim and streamlined, even
though the streamlining was of no use whatever in space. With blast holes
at each end, they looked like double-ended needles. The pilot's canopy in
the center controlled guns that fired through the front only. Rear guns
were handled by a gunner, who sat with back to the pilot.

Where Connie snapper-boats carried five men, the Federation boats carried
two. The Connies could fire in any direction. The Federation pilots aimed
by pointing the snapper-boat itself, as fighter pilots of conventional
aircraft had once aimed their guns.

Rip watched the boats approach. He was ready to duck inside if they
decided to look the asteroid over before landing. He hoped they wouldn't
catch sight of his two scouts. He also hoped his nervousness would vanish
when the fight started. He knew what to do, at least in theory. He had
gone through combat problems on the moon during training. But this was
different. This was real. The lives of his men depended on his being
right, and he was afraid of making a wrong decision.

Sergeant Major Koa, an experienced Planeteer with true understanding,
came and stood beside him. He said, "Guess I'll never get over being
jittery while waiting for the fight to start. I'm sweating so hard my
dehumidifier is humming like a Callistan honey lizard. But it doesn't
last long once the shooting begins. I get so busy I forget to be
jittery."

Before Rip could reply, the snapper-boats flashed over the cave, circled
the asteroid once, and landed on the dark side, close to the bomb
craters.

The first scout reported. "Santos, sir. I'm fifty yards beyond the stakes
where we had the first base. The snapper-boats landed between the first
two craters. Men coming out of one boat. I count six. Now they're coming
out of the other boat, but I can't see very well."

The other scout picked up the report, his voice thick with excitement. "I
can see them, sir! By Cosmos! There are seven in this boat on my side. I
am behind a rock forty yards to sunward of the second crater."

Rip turned up the volume of his communicator. "How are they armed?
Santos, report."

"One has a chatter gun. The rest have nothing."

"Pederson, report."

"No weapons I can see, sir."

Koa looked at Rip. "They must think the asteroid is clean. Otherwise
they'd have more than a chatter gun in sight. You can bet they have
knives and pistols, too."

Rip had been playing with an idea. He tried it on his men. "These Connies
would be useful to us alive, if we could capture them."

Dowst caught his meaning first. "As hostages, sir?"

"That's it. If we could capture them, the Connie cruiser would be
helpless. We could use the snapper-boat radios to warn the ship that any
false move would mean harm to their men."

Koa shook his head doubtfully. "I'm not sure the Connies worry about
their men, but it's worth the try. We can capture some of them if they
split up to search the asteroid. But we won't be able to sneak up on them
all."

"We have an advantage," Rip reminded them. "We've been on the asteroid
longer. We know our way around, and we're used to space walking. They've
just come out of deceleration, and they won't have their space legs yet."

Santos reported. "They're breaking up into groups of two. Three are
guarding the snapper-boats. One is the man with the chatter gun."

"Are their belt lights on?"

"Yes."

"Then keep out of the beams. Don't let them walk into you. Keep low, and
keep moving. Stay on the dark side."

"We'd better get to the dark side ourselves," Koa warned. He was right,
Rip knew. The Connies didn't have far to search before reaching the sun
side. "Koa, you take Trudeau and Kemp. I'll take Dowst and Dominico.
Nunez and Bradshaw stay here to guard the cave. If they arrive in twos,
let them get into the cave before you jump them. Bradshaw, how do you
feel?"

"I'm all right, Lieutenant."

Rip admired the Planeteer's nerve. He knew Bradshaw was in pain,
because bleeding into high vacuum was always painful. The crack in
the Englishman's helmet had let most of the air out, and his own blood
pressure had done the rest. He would carry the marks for days. A few more
moments, and all air and all heat would have been gone, with fatal
results. Fortunately, bubbles didn't shatter easily when cracked. To
destroy them took a good blow.

"All right. Let's travel. Koa, go right. I'll go the other way, and we'll
work around the asteroid until we meet."

Rip led the way, gliding as rapidly as he could toward the edge of
darkness. He called, "Santos. Anyone coming in the direction of the
cave?"

"Two pairs. About fifty yards apart. They will be out of my sight in a
few seconds."

That meant they would be within sight of Rip and the others. He knew Koa
had heard the message, too. Both groups put on more speed and reached the
safety of darkness. "Get down," Rip ordered. They could still be seen, if
silhouetted against the edge of sunlight.

Starlight gave a little light, but it was too faint to help much. Rip's
plan was that the Connies would supply the light needed for an attack.

In a few seconds, as Santos had predicted, belt light beams cut sharp
paths through the darkness. Rip sized up the possibilities. There were
two teams of two men each, and they were getting farther apart with each
step. One team was coming almost directly toward them. The other two men
slanted away from them and would soon be out of sight behind the thorium
crystals in which the cave was located. Fortunately, the Connies were
going away from the cave.

A Connie from the nearby team swung his beam back and forth, and it cut
space over their heads. Rip saw a few low pyramids of thorium a few rods
away. Quickly he ordered, "Dowst, hang on to my boots. Dominico, hang on
to Dowst's boots."

He lay face down on the metal ground until he felt hands grip his boots,
then he asked, "All set?"

Two voices answered, "Ready."

Rip put his gloves on the ground, then heaved forward and slightly upward
to overcome his inertia and that of his men. The trio moved slowly,
almost parallel with the surface. Once or twice Rip reached down to a
convenient crystal and put his strength into changing course and
altitude. Those were the only times when he felt the tug of his men.

He reached the first pyramid of thorium and directed, "Get behind these
rocks and stay down. Feel your way. Use me for a guide. I'll hold on
until you're under cover." He gripped a crystal. "Come on."

Dominico pulled himself along Dowst's prone form and then along Rip's.
When Dominico had reached the shelter of the crystals, Dowst crawled
along, with Rip's body for his guide, passed over him, and reached cover.
Rip followed.

The belt lights of the two Connies were almost abreast of them. Far to
their left, Rip saw another pair of lights. That was a pair he hadn't
seen before.

"We'll wait until they pass," he told his men. "Then we'll get up and
rush them from behind. They can't hear us coming. Dowst, you take the
near one. I'll take the far one. Dominico, you help as needed, but
concentrate on cutting off their equipment. The first thing we must do is
cut their communicators; otherwise they'll warn the rest. Then turn off
their air supplies and collapse their suits."

One thing was in their favor. The space suits worn by the Connies were
almost the same as theirs. The controls were of the same kind. The only
way to know a Connie was by his bubble, which was a little more tubular
than the round bubbles of the Federation.

Rip suddenly realized that he wasn't nervous anymore. He grinned. After
all, this was what he was trained for.

The Connies came abreast and passed. "Let's go," Rip said, and as he rose
he heard Koa's voice.

The sergeant major said, "Kemp, kneel on their right side. Trudeau and
I will hit them from the left and tumble them over you. Get their
communicators first."

Koa had his own methods and they sounded good.

Rip started slowly. He wanted to get directly behind the Connies. He
stayed down low until he was sure they couldn't see him unless they
turned.

Dowst and Dominico were right with him. "Come on," he said, and started
gliding after the helmeted figures. He kept his eyes on the one he had
selected, and he called on all the myriad stars of space to give him
luck. If the men turned, his plan for quick victory would fail.

He sensed his Planeteers beside him as the figures loomed ahead. He gave
a final spring that sent him through space with knees bent and outthrust,
his hands reaching.

His knees connected solidly with the Connie's thighs, and his hands
groped around the bulky space suit. He felt a rheostat control and
twisted savagely, then groped for the distinctive star-shaped button
of the air supply.

The Connie wrenched violently and threw them both upward. Rip felt the
star shape and twisted. If he could only deflate the Connie's suit! But
the man was writhing from his grip, clawing for a weapon.

Then Rip stopped reaching for the deflation valve. He grabbed his knife,
jerked it free, and thrust it against the middle of the Connie's back.
Then he clanged his bubble against the man's helmet for direct
communication and shouted, "Grab some space, or I'll let vack into
you!"

The Connie understood English. Most earthlings did. But even better was
his understanding of the pressure on his back. He stopped struggling; his
arms shot starward.

Rip breathed freely for the first time since he had leaped, and
exultation grew in him. He had his first man! His first hand-to-hand
fight had ended in victory so easily that he could hardly believe it.

He took time to look around him and saw that he was a good five feet
above the asteroid.

Below him, a Connie belt light sent its shaft parallel with the ground,
and he knew the second man was down.

The question was, had either of them shouted before their communicators
were cut off?

"Dowst," he called urgently. "All okay?"

"No," Dowst said grimly. "We got the Connie, but he got Dominico. Cut his
leg with a space knife. I'm putting a patch on it. You okay?"

"Yes. When you can, pull me down."

"Right you are."

Dominico spoke up. "Don't worry about me, sir. Nothing bad. I don't lose
much air."

"Fine, Dominico. Glad it wasn't worse."

But Rip knew it wasn't good, either. A cut with a space knife let air out
of the suit and created at least a partial vacuum. If it also cut flesh,
the vacuum let the blood pressure force out blood and tissue to turn a
minor wound into an ugly one.

They would have to bring this space flap with the Connies to a quick end,
Rip thought. He had to get his men into air somehow, to take a look at
their wounds. Bradshaw needed attention immediately, and now so did
Dominico.

Dowst reached up, took Rip's ankle, and pulled him down. Rip held on to
his captive. Then the private bound the Connie's hands, jerked his
communicator control completely off, and turned his air back on. Since
Rip had been unable to collapse the suit, the Connie was comfortable
enough. The reason for collapsing the suit was to deprive the enemy of
air instantly, so that he could be tied up while helpless from lack of
oxygen. There was enough air in the suit for only a few breaths once the
supply was cut off.

The Connie on the ground was neatly trussed. Rip's prisoner joined him.
Dowst switched off his belt light. "Now what, sir?"

Dominico was standing patiently nearby. He said nothing. Rip knew that no
more could be done for the Italian at present. "Go back to the cave,
Dominico," he ordered.

"I can stay with you, sir."

"No, Dominico. Thanks for the offer, but we'll get along. Go back to the
cave."

"Yes, sir."

Rip was a little worried. He had heard nothing from Koa since that first
exchange. He told Dowst as much. But Koa himself heard and answered.

"Lieutenant, we're all right. Got two Connies, and I don't think they had
a chance to yell. But I'm sorry about one, sir. Kemp had to swing at him
and busted his bubble."

"Fatal?"

"No, we patched it in time. But worse than Bradshaw."

"Tough." Rip couldn't feel too sympathetic.

After all, it was the Connie cruiser's fault Bradshaw had felt high vack.
"All right. We have four. That leaves nine."

Santos came on the circuit. "Sir, this is Santos. Only three men are at
the snapper-boats. If you could get here without being seen, maybe we
could knock them off. The rest wouldn't be much good if we had their
boats."

"You're right, Santos," Rip replied instantly. Why hadn't he seen that
for himself? He knew how he and Dowst could approach the craters without
being spotted, now that they had removed two teams of Connies. "We're on
our way. Koa, make it if you can."

"Yes, sir."

Dominico was already making his way back to the cave. Rip and Dowst
started for the horizon at a good walk, not afraid now to use their
lights, at least for a few yards. If any of the remaining Connie search
teams saw the lights, they would think they were their own men's.

Rip remembered the lay of the ground and Santos' description of the
snapper-boats' position. He circled almost to the horizon, then told
Dowst to cut his light. He cut his own. In a moment they topped the
horizon and, standing with only helmets visible from the snapper-boats,
looked the situation over.

The three Connies were standing between them and the boats. To the left
of the boats was the second crater. Rip studied the ground as best he
could in the Connie belt lights and decided on a plan of action. Calling
to Dowst, he circled again. Presently they were approaching the crater.
The Connies were just about twenty-five yards from the crater's opposite
rim.

Rip said, "I hate to do this, Dowst, but I can't see any way out. We have
to go into the crater."

Dowst merely said, "Yes, sir."

The extra radiation might put both of them well over the safety limits
long before Earth was reached, and they both knew it. He reached the
crater's edge and walked right down into it.

They were out of sight of the Connies now. Rip walked up the other side
of the crater until his bubble was just below ground level. The chunks of
thorium he had ordered thrown in to block some of the radiation made
walking a little difficult.

"Santos," he said, "we're in the second crater."

"Sir, I'm beyond the first, between two crystals. Pederson is near you
somewhere."

"Good. When I give the word, turn up your helmet light until they can see
a pretty good glow. Keep watching them." The bubbles were equipped with
lights, but they were seldom used. He outlined his plan swiftly. Both
Santos and Dowst acknowledged.

Koa reported in. "We're after two more Connies near the wreck of the
landing boat, sir."

"Be careful. Pederson, go help Koa. Nunez, how are things at the cave?"

"Nunez reporting, sir. Two Connies in sight, but they haven't seen us
yet."

"Let me know when they spot the cave."

"Yes, sir."

"Santos, go ahead."

For long moments there was silence. Rip felt for a solid foothold, found
one, and flexed his knees. He kept his back straight and his eyes on the
crater rim. His hands were occupied with two air bottles taken from his
belt, and his thumbs were on their valve releases. He waited patiently
for word from Santos that his helmet glow had been seen.

Santos yelled, "Now!"

Rip's legs straightened with a mighty thrust. He flashed into space
headfirst, at an angle that took him over the crater's rim and fifty feet
above the ground. He caught a glimpse of Santos' helmet, glowing like a
pink balloon, and of the three Connies facing it.

Rip's arms flashed above his head. His thumbs compressed. Air spurted
from the two bottles, driving him downward feetfirst, directly at the
heads of the Connies!



CHAPTER TEN

Get the Scorpion!


From the corner of his eye, Rip saw Dowst's heavy space boots and knew
the private was right with him. As they drove down, one of the Connies
stepped a little distance away from the others, probably to get a better
look at Santos. The Connie sensed something and turned, just as Rip and
Dowst flashed downward on his two mates.

Rip's boots caught one Connie where his bubble joined his suit, and the
impact drove the man downward to the unyielding surface of the asteroid
with a soundless smash. Rip threw up his arms to cushion his helmet as he
struck the ground beyond his enemy. He threw the air bottles away. He
fought to keep his feet under him and almost succeeded, but his knees hit
the ground, and pistol and knife bit into them painfully.

Two figures came into his view, locked tightly together, arms flailing.
It was Dowst and the second Connie. He got to his feet and was moving to
the Planeteer's aid when Santos' voice shrilled in his helmet. "Sir! Look
left!"

Rip whirled. The Connie who had stepped aside was advancing, pistol in
hand. His light caught Rip full in the face.

The young officer thought quickly. The Connie hadn't fired. Why? Suddenly
he had it. The man hadn't fired for fear of hitting his friend, who was
battling with Dowst. Rip was in front of them. Quickly he dropped to one
knee, reaching for his own pistol. The Connie wouldn't dare fire now. The
high-velocity slug would go right through him, to explode in one of the
struggling figures behind--and the wrong one might get it.

The Connie saw Rip's action and tossed his pistol aside. He, too, knew he
couldn't fire. He reached into a knee pouch and drew out his space knife.
He leaped for the Planeteer.

Rip pulled frantically at his pistol. It was stuck fast, probably caught
in the fabric by his knee landing. The space knife wouldn't be caught. It
was smooth, with no projections to catch. He shifted knees and jerked it
out.

The Connie's flying body hit him, and a powerful arm circled his waist.
Rip thrust upward with his knees, one hand reaching for the Connie's
suit valve. But the Connie had one arm free, too. He drove his glove up
under Rip's heart. Rip let go of the valve and used his elbow to lever
away, just as the Connie pressed his knife's release valve. The blade
slammed outward and drove into the inside of Rip's right arm, just above
the elbow.

Pain lanced through him, and he felt the blood rush to the wound as air
poured through the gap in his suit. He gritted his teeth and smashed at
the Connie with his own knife. It rammed home, and he squeezed the
release. The blade connected solidly. He was suddenly free.

He pressed the wounded arm to his side, stopping the outpouring of
air. The cut hurt like all the devils of space. With his other hand he
increased the air in his suit, then looked swiftly around. The Connie was
on his knees, both gloves pressed tightly to his side.

Dowst was just finishing a knot in the safety line that bound a second
enemy's hands. The Connie Rip had rocketed down on was still lying where
he had fallen. And Corporal Santos, the enemy's pneumatic chatter gun at
the ready, was standing guard.

Rip turned up the volume in his communicator. He tried to sound calm,
but the shakiness of triumph and excitement was in his voice. "All
Planeteers. We have the Connie snapper-boats. Koa, bring your men here."

He felt someone working on his arm and turned to see Corporal Pederson,
his face one vast grin in the glare from Dowst's belt light. "Koa didn't
need me," he said.

Rip grinned back. "Nunez," he called, "how are things at the cave?"

"Sir, this is Nunez. Two Connies were prowling around, but they didn't
see the entrance. Then, a minute ago, they hurried away."

Rip considered. "Koa, how many Connies have you?"

"Four, sir."

With the five he and Dowst had taken, that meant four sill at large, and
from Nunex's report, some Connie yelling had been going on. The four
certainly knew by this time that there were Federal men on the asteroid.
Unless something were done quickly the four Connies would be shooting at
them from the darkness. He ordered, "All Planeteers, kill your belt
lights."

The lights on the Connies they had just taken still glowed. Dowst was
putting a patch on the Connie Rip had stabbed. He waited until the
private had finished, then said, "Turn out the Connies' lights, too."

If he could get in touch with the Connies, he could tell them they were
finished. But using the snapper-boat radios was out, because the enemy
cruiser would hear. The cruiser couldn't hear the helmet communications,
though, because they carried only a short distance. The cruiser was close
enough so that a helmet communicator turned on full volume might barely
be heard, although it was unlikely.

He couldn't stick his head in a Connie helmet, but he could talk to a
Connie by direct communication and have him give instructions.

There was complete darkness with all belt lights out, but he groped his
way to the Connie Dowst had been patching, felt for his helmet, and put
his own against it. He yelled, "Do you hear me?"

"Yes." Then he asked, "Why did you patch me?"

It was a perfect opening. "Because we don't want to kill you. Listen. We
have all but four of you. Understand?"

"Yes. What will you do with us?"

"Treat you as prisoners--if you behave. Get on your communicator and tell
those four men to surrender. Tell them to come to the boats, with lights
on. Tell them we'll give them five minutes. If they don't come, we'll
hunt them with rockets. Make that clear."

"They will come," the Connie said. "They don't want to die. I will do
it."

Rip kept his helmet against the Connie's, but the man spoke in another
language, which Rip identified as the main Consops tongue. When he had
finished, Rip told his Planeteers to have weapons ready and to keep
lights off. Time enough for light when the Connies were all disarmed.

It didn't take five minutes. The Connie teams came quickly and willingly,
and they seemed almost glad to give up their pistols and knives. This was
not unusual. Rip had seen many Planeteer reports that spoke of the same
thing. Many Connies, it seemed, were glad to get away from the iron
Consops rule, even if it meant becoming Federation prisoners.

Inside one of the snapper-boats a light glowed. Rip put his helmet
against that of the man who had given the surrender order and demanded,
"What's that light?"

"The cruiser wants us."

Rip considered demanding that the Connie answer, then thought better of
it. He would do it himself. After all, they had hostages. The cruiser
wouldn't take any further action. He climbed into the snapper-boat and
hunted for the plug-in terminal. It fitted his own belt jack. He plugged
in and said, "Go ahead."

There was an instant of silence, then an accented voice demanded, "Why
are you speaking English?"

Rip replied formally, "This is Lieutenant Foster, Federation Special
Order Squadrons, in charge on the asteroid. Your landing party is in
our hands, as prisoners, two wounded, none dead. If you agree to
withdraw, we will send the wounded men back to you in one boat. The rest
will remain here as hostages for your good behavior."

"Stand by," the voice said. There was silence for several moments, then a
new voice said, "This is the cruiser commander. We make a counteroffer.
If you release our men and surrender to them, we will spare the lives of
you and your men."

Rip listened incredulously. The commanding officer didn't understand. He,
Rip, held the whip hand, because the lives of the Connie prisoners were
in his hands. He repeated his offer.

"And I repeat," the commander retorted. "Surrender or die. Choose now."

"I refuse," Rip stated flatly. "Try anything, and your men will suffer,
not us."

"You are mistaken," the harsh voice said. "We will sweep the asteroid
clean with our exhaust, but this time we will be more thorough. When
we have finished, we will hammer you with guided missiles. Then we will
send snapper-boats with rockets to hunt down any who remain. We intend to
have that thorium. You had better surrender."

Rip couldn't believe it. The cruiser commander had no hesitation in
sacrificing his own men! And it was not a bluff. He knew instinctively
that the Connie commander meant it. Instantly he unplugged the radio
connection from his belt and spoke urgently. "Koa, get everyone under
cover in the cave. Hurry! Collect all the Connies and take them with
you."

Then he plugged in again. "Commander, I must have time to think this
over."

"You have one minute."

He watched his chronometer, planning the next move. When the minute
ended, he asked, "Commander, how do we know you will spare our lives if
we surrender?" Through the transparent shell of the snapper-boat he saw
lights moving toward the horizon and knew Koa was following orders.

"You don't know," the cruiser answered. "You must take our word for it.
But if you surrender, we have no reason to wish you harm."

Rip remained silent. The seconds ticked past until the commander snapped,
"Quickly! You have no more time."

"Sir," Rip said plaintively, "two of my men do not wish to surrender."

"Shoot them, fool! Are you in command or not?"

Rip grinned. He made his voice whine. "But, sir, it is against the law of
the Federation to shoot men without a trial."

The commander lapsed into his own language, caught himself, then barked,
"You are no longer under Federation law. You are under the Consolidation
of People's Governments. Do you surrender or not? Answer at once, or we
take action anyway. Quick!"

Rip knew he could stall no longer. He said coolly, "If you had brains
in your head instead of high vacuum, you'd know that Planeteers never
surrender. Blast away, you filthy space pirate!"

He jerked the plug loose, hesitated for a second over whether or not to
take the snapper-boat, and decided against it. He wasn't familiar with
Connie controls, and there wasn't time to experiment. He headed for the
cave.

The Connie cruiser lost no time. Its stern tubes flamed, then its
steering tubes. It was going to drive directly at the asteroid without
making a long run! Rip estimated quickly and realized that the Connie
would get to the asteroid at the same time that he reached the cave--if
he made it.

He speeded up as fast as he dared. With little gravity on the asteroid,
he couldn't fall, but a false step could lift him into space and make
him lose time while he got out an air bottle to propel him down again.
The thought gave him an idea. Without slowing he took two bottles from
his belt, turned them so the openings pointed backward, squeezed the
release valves.

The Connie was gaining speed, blasting straight toward him. Rip sped
forward and crossed to the sun side, intent on the cave entrance but no
longer sure he would make it. The Connie's nose tube shot a cylinder of
flame forward, reaching for the asteroid. He saw the fire lick downward
and sweep toward him with appalling speed as he put everything he had
into a frantic dive for the cave entrance. The flaming rocket exhaust
seemed to snatch at him as a dozen hands pulled him to safety, then beat
the sparks from his suit.

He was safe. He leaned against Koa, his heart thumping wildly. For a
moment or two he couldn't speak; then he managed, "Thanks."

Koa spoke for the Planeteers. "We're the ones to say thanks, sir. If you
hadn't thought of stalling the cruiser, and if you hadn't stayed behind
to give us time, we'd have some casualties, and so would the Connies we
captured."

"There wasn't anything else I could do," Rip replied. "Come on, Koa.
Let's see what the cruiser is doing."

They stepped outside. The metal was already cold again. Things didn't
stay hot in the vacuum of space.

They didn't see the Connie until the fire of its exhaust suddenly blasted
above the horizon, and then they ducked for cover. The cruiser had taken
a swing at the other side of the asteroid. They peered out again and saw
it turning.

"He won't get us," Rip said confidently. "Our tough time will come when
he sends a fleet of snapper-boats."

"We'll get a few," Koa replied grimly. "Wait! What's he doing?"

The cruiser had started for the asteroid. Suddenly jets flamed from every
quarter of the ship. He was using all steering jets at once! Rip watched,
bewildered, as the great ship spun slowly, advanced, then settled to a
stop just at the horizon.

"He can't be launching boats already," he said worriedly. "What's he up
to?"

They ran forward a short distance until they could see below the cave's
horizon level. The cruiser released exhausts from both sides of the ship,
the outer ones the slightest bit stronger. Rip exclaimed, "Great Cosmos,
he's cuddling right up to the asteroid! Why?"

"Hiding," Koa said. "By Gemini! Come on, sir!"

Rip saw his meaning instantly, and they raced to the side of the asteroid
away from the ship. As they crossed into the dark half, Rip looked back.
He couldn't see the cruiser from here. But he looked out into space,
across the horizon, and knew that Koa's guess had been right. The
distinctive glow of a nuclear drive cruiser was clear among the stars.

The _Scorpius_ had returned!

"The Connie saw it," Rip said worriedly, "but didn't blast away. That
means he's intending to ambush the _Scorpius_. Koa, if he does, that
means war."

The tall officer shook his head. "Sir, the Connie has guided missiles
with atomic warheads, just as our ship has. If he can launch one from
ambush and hit our ship, that's the end of it. The _Scorpius_ will be
nothing but space junk. Commander O'Brine will never have time to get
off a message, because he'll be dead before he knows there is danger."

The logic of it sent a chill down Rip's spine. The Connie could get the
_Scorpius_ with one nuclear blast and then clean up the asteroid at
leisure. The Federation would suspect, but it would be unable to prove
anything, because there would be no witnesses. If the Connie took time to
tow the remains of the _Scorpius_ deep into the asteroid belt, it likely
would never be found, no matter how the Federation searched.

They had to warn the ship. But how? Their helmet communicators wouldn't
reach it until it was right at the asteroid, and that would be too late.
They had no other radio. If only the radios in the snapper-boats were on
a Federation frequency.... Hey! They could take one of the boats and
intercept the cruiser!

He was hurrying toward them before Koa understood what he was saying. He
tried to make his legs go faster, but they were unsteady. He knew he was
losing blood. He had lost plenty. He gritted his teeth and kept going.

The snapper-boats seemed miles away to Rip, but he plugged ahead until
his belt light picked them up. He took a long look, then turned away,
heartsick. The Connie's exhaust had charred them into wreckage.

"Now what?" he asked.

"I don't know, sir," Koa answered somberly.

They went back to the cave, not hurrying because Rip no longer had the
strength to hurry. Weakness and a deep desire to sleep almost overcame
him, and he knew that he was finished, anyway. His wound must be too deep
to clot, which meant it would bleed until he bled to death. Whether he
warned the _Scorpius_ or not, his end was the same.

Back in the cave, he leaned against the wall and asked tiredly. "How is
Dominico?"

"I am fine, sir. My wound stopped bleeding."

"How is the Connie I got?"

"Unconscious, sir," Santos replied. "He must be bleeding badly, but we
can't tell. The one you landed on is all right now, but he may have a
broken rib or two."

Because his voice was weak, Rip had to turn up the volume on his
communicator to tell the Planeteers about the _Scorpius_. They were
silent when he finished. Then Dowst spoke up.

"Looks like they have us, sir. But we'll take plenty of them with us
before we're finished."

"That's the spirit," Rip told them. "I won't last much longer. When I get
too weak, Koa will take over. Meanwhile, I want to get outside. Bring the
rocket launcher outside, too. Who's the gunner? Santos? Stand by, then.
We'll need you, in case the Connie decides to send a few snappers before
it goes after the Scorpius."

The cruiser's glow was plain above the horizon now. It was so close that
they could make out its form against the background of stars. O'Brine was
decelerating, and Rip was certain he was watching his screens for a sign
of the enemy. He would see nothing, because the enemy was in the shadow
of the asteroid. He would think the coast was clear and would come to a
stop nearby while he asked why Rip had called for help. Failing to get a
reply, since the landing boat was wrecked, he would send a landing party,
and the Connie would attack while he was launching boats, off guard.

Rip watched the prediction come true. The nuclear cruiser slowed
gradually, its great bulk nearing the asteroid. O'Brine was operating as
expected.

Rip was having trouble keeping his vision from blurring. He leaned
against the rocket launcher, and his glove caressed one of the sharp
noses in the rack.

He heard his own voice before the idea had even taken full form. "Santos!
Do you hear me? Santos! Get the _Scorpius_! Fire before it comes to a
stop. And don't miss!"

Santos started to protest, but Koa bellowed, "Do it! The lieutenant's
right. It's the only chance we've got to warn the ship. Get the scorpion,
Santos. Dead amidships!"

The young corporal swung into action. His space gloves flew as he cranked
the launcher around, turned on the illuminated sight, and bent low over
it. Rip stood behind the corporal. He saw the cruiser's shape stand out
in the glow of the sight, saw the sighting rings move as Santos corrected
for its speed.

The corporal fired. Fire flared back past his shoulder. The rocket
flashed away, its trail dwindling as it sped toward the great bulk
above. It reached _Brennschluss_, and there was darkness. Rip held his
breath for long seconds, then gave a weak cry of victory.

A blossom of orange fire marked a perfect hit.



CHAPTER ELEVEN

Hard Words


The _Scorpius_ could have taken direct hits with little or no major
damage from a hundred rockets of the kind Rip had used, but Commander
O'Brine took no chances. When the alarm bell signaled that the outer hull
had been hit, the commander acted instantly with a bellowed order.

The Planeteers on the asteroid blinked at the speed of the cruiser's
getaway. Fire flamed from the stern tubes for an instant, and then there
was nothing but a fading glow where the _Scorpius_ had been.

Rip had a mental image of everything movable in the ship crashing against
bulkheads with the terrific acceleration.

And in the same moment, the Consops cruiser reacted. The Connie commander
was ready to fire guided missiles, when his target suddenly,
mysteriously, blasted into space at optimum acceleration. There was only
one reason the Connie could imagine: His cruiser had been spotted. The
ambush had failed. It was one thing for the Connie to lie in ambush for
a single, deadly surprise blast at the Federation cruiser. It was quite
another to face the nuclear drive ship with its missile ports cleared for
action. The Connie knew he had lost.

Rip and the Planeteers saw the Consops ship suddenly flame away, then
turn and dive for low space below the asteroid belt, in a direction
opposite to the one the _Scorpius_ had taken. The Planeteers' helmet
communicators rang with their cheers.

The young officer clapped Santos on the shoulder and exclaimed weakly,
"Good shooting!"

The corporal turned anxiously to Koa. "The lieutenant's pretty weak.
Can't we do something?"

"Forget it," Rip said. There was nothing anyone could do. He was trapped
inside his space suit. There was nothing anyone could do for his wound
until he got into air.

Koa untied his safety line and moved to Rip's side. "Sir, this is
dangerous, but there's just as much danger without it. I'm going to tie
off that arm."

Rip knew what Koa meant. He stood quietly as the big sergeant major put
the line around his arm above the wound, then put his massive strength
into the task of pulling the line tight.

The heavy fabric of the suit was stiff, and the air pressure gave further
resistance that had to be overcome. Rip let most of the air out of the
suit, then fought for breath until the pain in his arm told him that Koa
had succeeded. He inflated the suit again and thanked the sergeant major
weakly.

The tight line stopped the bleeding, but it also cut off the air
circulation. Without the air, the heating system couldn't operate
efficiently. It was only a matter of time before the arm froze.

"Stand easy," Rip told his men. "Nothing to do now but wait. The
_Scorpius_ will be back." He set an example by leaning against the
thorium crystal in which the cave was located. It was a natural but
rather meaningless gesture. With virtually no gravity pulling at them,
they could remain standing almost indefinitely, sleeping upright.

Rip closed his eyes and relaxed. The pain in his arm was less now, and he
knew the cold was setting in. He was getting lightheaded, and, most of
all, he wanted to sleep. Well, why not? He slumped a little inside the
suit.

He awoke with Koa shaking him violently. Rip stood upright and shook his
head to clear his vision. "What is it?"

"Sir, the _Scorpius_ has returned."

Rip blinked as he stared out into space to where Koa was pointing. He had
trouble focusing his eyes at first, and then he saw the glow of the
cruiser.

"Good," he said. "They'll send a landing boat first thing."

"I hope so," Koa replied.

Rip wanted to ask why the big Planeteer was dubious, but he was too tired
to phrase the question. He contented himself with watching the cruiser.

In a short time the _Scorpius_ was balanced, with nose tubes
counteracting the thrust of stern tubes, ready to flash into space again
at a second's notice.

Rip watched, puzzled. The cruiser was miles away. Why didn't it come any
closer? Then suddenly it erupted a dozen fiery streaks.

"Snapper-boats!" someone gasped.

Rip jerked fully awake. In the ruddy glow of the fighting rockets' tubes,
he had seen that the cruiser's missile ports were yawning wide, ready to
spew forth their deadly nuclear charges in an instant.

The snapper-boats flashed toward the asteroid in a group, sheered off,
and broke formation. They came back in pairs, streaking space with the
sparks of their exhausts.

"Into the cave," Koa shouted.

The Planeteers obeyed instantly. Koa took Rip's arm to lead him inside,
but the young officer shook him off. "No, Koa. I'll take my chances out
here. I want to see what they're up to."

"Great Cosmos, sir! They'll go over this rock like Martian beetles.
You'll get it, for sure."

"Get inside," Rip ordered. He gathered strength enough to make his voice
firm. "I'm staying here until I figure out some way to call them off. We
can't just stand here and let them blast us. They're our own men."

"Then I'm staying, too," Koa stated.

A pair of snapper-boats flashed overhead and vanished below the horizon.
Two more swept past from another direction.

Rip watched, curious. What were they up to? Another pair quartered past
them at high speed, then two more. The boats seemed to be crisscrossing
the asteroid in a definite pattern.

A pair streaked past, and something sped downward from one of them,
trailing yellow flame. It exploded in a ball of molten fire that licked
across the asteroid in waves. Rip tensed, then saw that the chemical
would burn out before it reached them.

"Fire bomb," Koa muttered.

Rip nodded. He had recognized it. The Planeteers were trained in the use
of fire bombs, tanks of chemicals that burned even in an airless world.
They were equipped with simple jets for use in space.

The snapper-boats drew off, back toward the _Scorpius_. Rip watched,
searching for some reason for their actions. Then one of the boats
pulled away from the others. It returned to the asteroid, with stern jet
burning fitfully.

"Is he landing?" Koa asked.

Rip didn't know. The snapper-boat was moving slowly enough to make a
landing.

Directly above the asteroid it changed direction, circled, and returned
over their heads. Rip could almost have picked it off with a pistol shot.
Santos could have blasted it into space dust with one rocket.

The snapper-boat changed direction, and for a fraction of a second stern
and side tubes "fought" each other, making the boat yaw wildly. Then it
straightened out on a new course.

Koa exclaimed, "That's a drone!"

Rip got it then. A pilotless snapper-boat! That's why its actions were a
little uneven. Only one thing could explain its deliberate slowness. It
was bait. The _Scorpius_ had sent piloted snapper-boats over the asteroid
at high speed, crisscrossing in order to cover the thorium world
completely, expecting to have the unknown rocketeer fire at them. Then a
fire bomb had been dropped as a further means of getting the asteroid to
fire. But no rockets had been fired from the asteroid, so the pilot in
control of the drone had sent it at low speed, a perfect target.

That meant O'Brine wasn't sure of what was going on. He must have seen
the blip on his screen as the Connie cruiser flamed off, Kip reasoned.
But the commander probably suspected that the Connies had overcome
the Planeteers and were in control of the asteroid. He had sent the
snapper-boats to try to draw fire, in an attempt to find out more surely
whether Planeteers or Connies had the thorium rock.

"The _Scorpius_ doesn't know what's going on," Rip told his Planeteers.
"O'Brine didn't know the cruiser was waiting to ambush him, so the rocket
we fired made him think the Connies had taken us over."

He put himself in O'Brine's place. What would his next step be? The
snapper-boats hadn't drawn fire, even when a drone was sent over at low
speed. The next thing would be to send a piloted boat over slowly enough
to take a look.

Rip hoped O'Brine would hurry. There was no longer any feeling in his arm
below Koa's safety line. That meant the arm had frozen. He had to get
medical attention from the _Scorpius_ pretty soon.

He gritted his teeth. At least he was no longer losing blood. He wasn't
getting any weaker. But every now and then his vision fogged, and he had
to shake his head to clear it.

The pilotless snapper-boat made another slow run, then put on speed
and flashed back to the group of boats near the cruiser. Another boat
detached itself from the squadron and moved toward the asteroid.

Rip wished for a communicator powerful enough to reach the _Scorpius_,
but he knew it was useless to try with his helmet circuit. The carrier
waves of the snapper-boats were on the same frequency, and they would
smother the faint signal from his bubble.

But the boats might be able to hear if they got close enough! He had a
swift memory of the communications circuits. The pilots were plugged into
their boat communicators. If a boat got near enough, he could turn up his
bubble to full volume and yell. Not only would the boat pilot hear him,
but also his voice would go through the pilot's circuit and be heard in
the ship!

Rip grabbed Koa's arm. "Let's move away from the cave a little farther."

The two of them stepped away from the cave and stood in full view as the
snapper-boat moved cautiously down toward the asteroid. Rip planned what
he would say. "Commander O'Brine, this is Foster!"

No, that wouldn't do. Connies would know that Kevin O'Brine commanded the
_Scorpius_, and if they had taken over the Planeteers on the asteroid,
they would also have learned Rip's name. He had to say something that
would immediately identify him beyond the shadow of a doubt.

The snapper-boat was closing in slowly. Rip knew the pilot and gunner
must be tense, frightened, ready to blast with their guns at the first
wrong move on the asteroid. He groped with his good arm and turned up his
helmet communicator to full volume.

The fighting rocket drew closer, cut in its nose tube, and hovered only a
few hundred feet above the Planeteers.

Rip summoned enough strength to make his voice sharp and clear. His words
sped through space into the bubble of the pilot, echoed in the helmet,
were picked up by the pilot's microphone, and then were hurled through
the snapper-boat circuit and through space to the cruiser's control room.

O'Brine stiffened as the speaker threw Rip's voice at him, amplified and
hollow-sounding from reverberations in the snapper-boat pilot's helmet.

"_O'Brine is so ugly he won't look at his face in a clean blast tube!
That no-good Irishman wouldn't know what to do with an asteroid if he had
one!_"

The commander turned purple with rage. He bellowed, "Foster!"

A junior space officer hid a grin and murmured, "Looks like the
Planeteers still have the asteroid."

O'Brine bent over the communicator and yelled, "Deputy commander! Launch
landing boats. Get those Planeteers and bring them here under armed
guard. Ram it!"

The snapper-boat pilot through whose circuit Rip had yelled turned to
look wide-eyed at his gunner. "Did you hear that? Throw a light down on
the asteroid. It must have come from there."

The gunner threw a switch, and a searchlight port opened in the boat's
belly. Its beam searched downward, swept past, then steadied on two
space-suited figures.

"It worked," Rip said tiredly. He closed his eyes to guard them against
the brilliant glare, then waved his good arm.

Santos called from the cave entrance. "Sir, landing boats are being
launched!"

"Bring out the prisoners," Rip ordered. "Line them up. Planeteers fall in
behind them."

The landing boats, with snapper-boats in watchful attendance, blasted
down to the surface of the asteroid. Spacemen jumped out, awkward at
first on the no-weight surface. An officer glided to meet Rip, and he had
a pistol in his hand.

"It's all right," Rip told him. "The Connies are our prisoners. You won't
need guns."

The spaceman snapped, "You're under arrest."

Rip stared incredulously. "What for?"

"The commander's orders. Don't give me any arguments. Just get aboard."

"I can't argue with a loaded gun," Rip said wearily. He called to his
men. "We're under arrest. I don't know why. Don't try to resist. Do as
the spacemen order."

Rip got aboard the nearest landing boat, his head spinning. O'Brine had
made a mistake of some kind.

The landing boats, loaded with Planeteers and Connies, lifted from the
asteroid to the cruiser. They slid smoothly into the air locks and
settled. The massive lock doors slid closed and lights flickered on. Rip
waited, trying to keep consciousness from slipping away.

The lock gauges registered normal air, and the inner valves slid open.
Commander O'Brine stepped through, his square jaw outthrust and his face
flushed with anger. He bellowed, "Where's Foster?"

His voice was so loud that Rip heard him even through the bubble. He
stepped out of the boat and faced the irate commander.

O'Brine ordered, "Get him out of that suit."

Two spacemen jumped forward. One twisted Rip's bubble free and lifted it
off. The heavy air of the ship hit him with physical force.

O'Brine grated, "You're under arrest, Foster, for firing on the
_Scorpius_, for insubordination, and for conduct unbecoming an officer.
Get out of that suit and get flaming. It's the space pot for you."

Rip had to grin. He couldn't help it. He started to reply, but the heavy
air of the cruiser, so much richer and denser than that of the suits, was
too much. He fell, unconscious.

There was no gravity to pull him to the floor, but the action of his
relaxing muscles swung him slowly until he lay facedown in the air a
few feet above the floor.

Commander O'Brine stared for a moment, then took the unconscious
Planeteer and swung him upright. His quick eyes took in the patch
on the arm, the safety line tied tightly. He roared, "Quick! Get him
to the wound ward!"

       *       *       *       *       *

Rip came back to consciousness on the operating table. The wound in his
arm had been neatly repaired, and below the wound, where his arm had
frozen, a plastic temperature bag was slowly bringing the cold flesh back
to normal. On his other side, a pulsing pressure pump forced new blood
from the ship's supplies into his veins.

A senior space officer, with the golden lancet of the medical service on
his tunic, bent over him. "How do you feel?"

Rip's voice surprised him. It was as full and strong as ever. "I feel
wonderful. Can I get up?"

"When we get enough blood into you, and your arm is fully restored."

Commander O'Brine appeared in the door frame. "Can he talk?"

"Yes. He's fine, sir."

O'Brine glared down at Rip. "Can you give me a good reason why I
shouldn't have you treated for space madness and then toss you in the
space pot until we reach Earth?"

"Best reason in the galaxy," Rip said cheerfully. "But before we talk
about it, I want to know how my men are. One got cut, and another had his
bubble cracked. Also, one of the Connies got badly cut, another had some
broken bones, and a third one bled into high vack when Koa cracked his
bubble."

The doctor answered Rip's question. "Your men are all right. We put the
one with the cracked bubble into high compression for a while, just to
relieve his pain a little. The other one didn't bleed much. He's back in
the squad room right now. Two of the prisoners are patched up, but the
third one is in the other operating room. I don't know whether we can
save him or not. We're trying."

O'Brine nodded. "Thanks, Doctor. Now, Foster, start talking. You fired
on this ship, scored a hit, and broke the air seal. No casualties,
fortunately. But by forcing us to accelerate at optimum speed, you caused
so much breakage of ship's stores that we'll have to put into Marsport
for new stocks. And on top of all that, you insulted me within the
hearing of every man on the ship. I don't mind being insulted by
Planeteers. I'm used to it. But when it's done over the communications
system, it's bad for discipline."

Rip tried to keep a straight face. He said mildly, "Sir, I'm surprised
you even give me a chance to explain."

"I wouldn't have," O'Brine said frankly. "I would have shot off a special
message to Earth, relieving you of command and asking for Discipline
Board action. But when I saw those Connie prisoners, I knew there was
more to this than just a young space pup going vack-wacky."

"There was, Commander." Rip recited the events of the past few hours
while the Irishman listened with growing amazement. "I had to convince
you in a hurry that we still held the asteroid, so I used some insulting
phrases that would let you know, without any doubt, who was talking. And
you did know, didn't you, sir?"

O'Brine flushed. For a long moment his glance locked with Rip's, then he
roared with laughter.

Rip grinned his relief. "My apologies, sir."

"Accepted," O'Brine chuckled. "I'm rather sorry I don't have an excuse
for dumping you in the space pot, though, Foster. Your explanation is
acceptable, but I have a suspicion that you enjoyed calling me names."

"I might have," Rip admitted, "but I wasn't in very good shape. The only
thing I could think of was getting into air so I could have my arm
treated. Commander, we've moved the asteroid. Now we have to correct
course. And we have to get some new equipment, including nuclite
shielding. Also, sir, I'd appreciate it if you'd let my men clean up and
eat. They haven't been in air since we left the cruiser."

For answer, O'Brine strode to the operating-room communicator. "Get it,"
he called. "The deputy commander will prepare landing boat one and issue
new space suits and helmets for all Planeteers with damaged equipment.
Put in two rolls of nuclite. Sergeant Major Koa will see that all
Planeteers have an opportunity to clean up and eat. They will return to
the asteroid in one hour."

Rip asked, "Will I be able to go into space by then?"

The doctor replied, "Your arm will be normal in about twenty minutes. It
will ache some, but you'll have full use of it. We'll bring you back to
the ship in about twenty-four hours for another look at it, just to be
sure."

Sixty minutes later, clean, fed, and contented, the Planeteers were again
on the thorium planet, while the _Scorpius_, riding the same orbit, stood
by a few miles out in space.

The asteroid and the great cruiser arched high above the belt of tiny
worlds in the orbit Rip had set, traveling together toward distant Mars.



CHAPTER TWELVE

Mercury Transit


The long hours passed, and only Rip's chronometer told him when the end
of a day was reached. The Planeteers alternately worked on the surface
and rested in the air of the landing boat compartment, while the asteroid
sped steadily on its way.

When a series of sightings over several days gave Rip enough exact data
to work on, he recalculated the orbit, found the amount that the course
had to be corrected, and supervised the cutting of new holes in the
metal.

Tubes of ordinary rocket fuel were placed in these and fired, and the
thrust moved the asteroid slightly, just enough to make the corrections
Rip needed. It was not necessary to take to the landing boat for these
blasts. The Planeteers retired to their cave, which was now lined with
nuclite as a protection against radiation.

Rip watched his dosimeter climb steadily as the radiation dosage mounted.
Then he took the landing boat to the Scorpius, talked the problem over
with the ship's medical department, and arranged for his men to take
injections that would keep them from getting radiation sickness.

They left the asteroid belt far behind and passed within ten thousand
miles of Mars. The _Scorpius_ sent its entire complement of snapper-boats
to the asteroid for protection, in case Consops made another try, then
flamed off to Marsport to put in new supplies to replace those damaged
when Rip had forced sudden and disastrous acceleration.

The asteroid had reached Earth's solar orbit before the cruiser returned,
though Earth itself was on the other side of the sun. Rip ordered a
survey and found the best place on the dark side to make a new base. The
Planeteers cut out a cave with the torch, lined it with nuclite, and
moved in the supplies. It would be their base to the end of the trip.

The sun was very hot now. On the sunny side of the asteroid the
temperature had soared far past the boiling point of water. But on the
dark side, Rip measured temperatures close to absolute zero.

When the _Scorpius_ returned, he arranged with Commander O'Brine for the
Planeteers to take turns going to the cruiser for showers and decent
meals.

The asteroid approached the orbit of Venus, but the bright planet was
some distance away, at its greatest elongation to the east of the sun.
Mercury, however, loomed larger and larger. They would pass close to the
hot planet.

O'Brine recalled Rip to the _Scorpius_ and handed him a message.

  Asteroid now within protection reach of Mercury and Terra bases. Your
  escort no longer required. Proceed immediately Titan, take on cargo and
  personnel.

The commander sighed. "Looks like I'll never get to Earth long enough to
see my family."

Rip sympathized. "Tough, sir. Perhaps the cargo from Titan will be
scheduled for Terra."

"That's what I hope," O'Brine agreed. "Well, here's where we part. Is
there anything you need?"

Rip made a mental check on supplies. He had more than enough. "The only
thing we need is a long-range communicator, sir. We'll need one to
contact the planet bases."

"I'll see that you get one." The Irishman thrust out his hand. "Stay
out of high vack, Foster. Too bad you didn't join us instead of the
Planeteers. I might have made a decent officer out of you."

Rip grinned. "That's a real compliment, sir. I might return it by saying
that you have the makings of a Planeteer officer yourself."

O'Brine chuckled. "All right. Let's declare a truce, Planeteer. We'll
meet again. Space isn't very big."

A short time later Rip stood in front of his asteroid base and watched
the great cruiser drive into space. A short distance away a snapper-boat
was lashed to the landing boat. O'Brine had left it, with a word of
warning.

"These Connies are plenty smart. I don't like leaving you unprotected,
even within reach of Mercury and Terra, but orders are orders. Keep the
snapper-boat, and you'll at least be able to put up a fight if you bump
into trouble."

The asteroid sped on its lonely way for two days, and then a cruiser came
out of space, its nuclear drive glowing. The Planeteers manned the rocket
launcher, and Rip and Santos stood by the snapper-boat, just in case, but
the cruiser was the _Sagittarius_, out of Mercury.

Capt. Go Sian-tek, a Chinese Planeteer officer, arrived in one of the
cruiser's boats with three enlisted men.

Captain Go greeted Rip and his men, then handed over a plastic stylus
plate ordering Rip to deliver six cubic meters of thorium for use on
Mercury. While Koa supervised the cutting of the block, Rip and the
captain chatted.

The Mercurian Planeteer base was in the twilight zone, but the Planeteers
always worked on the sun side, wearing special alloy suits to mine the
precious nuclite that only the hot planet provided.

At some time during its first years, Mercury had been so close to the
sun that its temperature was driven high enough to permit a subatomic
thermonuclear reaction. The reaction had shorn some elements of their
electrons and left a thin coating of material composed almost entirely
of neutrons. The nuclite was incredibly dense. It could be handled only
in low gravity because of its weight. But nothing else provided the
shielding against radiation and meteors half so well, and it was in great
demand.

"Things aren't so bad," Go told Rip. "The base is comfortable, and we
only work a two-hour shift out of each ten. We've had a plague of silly
dillies recently. They got into one man's suit while we were working, but
mostly they're just a nuisance."

Rip had heard of the creatures. They were like Earth armadillos, except
that they were silicon animals and not carbon like those of Earth. They
were drawn to oxygen like iron to a magnet, and their diamond-hard
tongues, used for drilling rock in order to get the minerals on which
they lived, could drive right through a space suit. Or, if these animals
worked undetected for a while, they could drill through the shell of a
space station.

_Scralabus primus_ was the scientific name of the creature, but the fact
that it looked like a silicon armadillo had given it the popular name of
"silly dilly." Apart from its desire for oxygen, it was harmless.

Koa reported, "Sir, the block of thorium is ready. We've hung it on a
line behind the landing-boat. The blast won't hurt it, and it's too big
to get inside the boat."

"Fine, Koa. Well, Captain, that does it."

The Mercurian Planeteers got into their craft and blasted off, trailing
the block of thorium in their exhaust. Rip watched the cruiser take the
craft and thorium aboard, then drive toward Mercury, brilliant sunlight
reflecting from its sleek sides. The planet was only a short distance
away by spaceship. It was the largest thing in space, except for the sun,
as seen from the asteroid.

Past the orbit of Mercury, the sun side of the asteroid grew dangerously
hot for men in space suits. Rip and the Planeteers stayed in the bitter
cold of the dark side, which ceased to be entirely dark. The temperature
rose somewhat. They were close enough to the sun that the prominences,
great flaming tongues of hydrogen that sped many thousands of miles into
space, gave them light and enough heat to register on Rip's instruments.

Mercury was left far behind, and Earth could not be seen because of the
sun. There was nothing to do now but ride out the rest of the trip as
comfortably as possible, until it was time to throw the asteroid into
a series of ever-tightening elliptical orbits around Earth, known as
braking ellipses. The method would use Earth's gravity to slow them down
to the proper speed. A single atomic bomb and a half dozen tubes of
rocket fuel remained.

Then, as Rip was enjoying the comfort of air during his off-watch hour in
the boat compartment, Koa beat an alarm on the door.

Rip and the Planeteers got into suits and opened up.

"It's Terra base calling on the communicator, sir," Koa reported. "Urgent
message, they said, and they want to talk to you personally."

Rip hurried to the cave. The communicator indicator light was glowing
bright red. He plugged in his helmet circuit and said, "This is
Lieutenant Foster. Go ahead."

A voice crackled across space from Earth. "This is Terra base. Foster,
a Consops cruiser has apparently been hiding behind the sun waiting for
you. Our screens just picked it up, heading your way. We've sent orders
to the _Sagittarius_ on Mercury to give you cover, and the _Aquila_ has
taken off from here. But get this, Foster. The Consops cruiser will reach
you first. You have about one hour. Do you understand?"

Rip understood all right. He understood too well. "Got you," he said
shortly. "Now what?"

The communicator buzzed. "Take any appropriate action. You're on your
own. Sorry. Sending the cruisers is all we can do. We'll stand by for
word from you. If you think of any way we can help, let us know."

Rip asked, "How long before the cruisers arrive?"

"You're too close to us for them to move fast. They'll have to use time
accelerating and decelerating. The _Sagittarius_ should arrive in
something less than two hours and the _Aquila_ a few minutes later."

The communicator paused, then continued. "One thing more, Foster. The
Connies know how badly we want that asteroid, but they also know we don't
want it enough to start a war. Got that?"

"Got it," Rip stated wryly. "I got it good. Thanks for the warning, Terra
base. Foster off."

"Terra base off. Stay out of high vack."

Fine advice, if it could be taken. Rip stared up at the brilliant stars,
thinking fast. The Connie would have almost an hour's lead on the
space-patrol cruisers. In that hour, if the Connie were willing to pay
the price in blasted snapper-boats, Consops would have the asteroid. And
Terra base had made it clear that the space patrol would not try to blast
the Connie cruiser, because that would mean war.

Added together, the facts said just one thing: They had one hour in which
to think of some way to hold off the Connies for an additional hour.

The Planeteers were clustered around him. Rip asked grimly, "Any of you
ever study the ancient art of magic?"

The Planeteers remained silent and tense.

"Magic is what we need," Rip told them. "We have to make the whole
asteroid disappear, or else we have to conjure up a space cruiser out
of the thorium. Otherwise, we have barely an hour till we're either
prisoners or dead!"



CHAPTER THIRTEEN

Peril!


Sergeant major Koa asked thoughtfully, "Sir, would it do the Connie much
good to launch boats this close to the sun? They'd have to use too much
fuel just keeping position."

"You could be right," Rip said slowly. Koa had a point! To counter
gravitational attraction took velocity, which meant consumption of fuel.
Maneuvering boats meant rapid velocity changes. Against the sun's
terrific gravity at this distance, it also meant maximum thrust and
maximum fuel flow most of the time. The asteroid, in a planned orbit with
the correct velocity, was safe enough, and the Connie cruiser would
simply match the asteroid's orbit. But boats, which had to maneuver, were
another matter.

Rip figured quickly. In accordance with Newton's Law, gravitational
attraction increased rapidly on approaching a body. If he could put the
asteroid even closer to the sun, the boat problem would become worse,
until even a small velocity change in the wrong direction could leave
a boat in the terrible position of not having enough thrust for a long
enough time to keep from being drawn into the sun.

But to change the asteroid's orbit was dangerous! It meant losing just
enough velocity to be drawn closer to the sun, and then picking up a much
higher velocity to get free again!

Rip got his instruments and pulled out a special slide rule designed for
use in space. He had Koa stand by with stylus and computation board and
take down his figures.

He recalculated the safety factor he had used when deciding how close
to the sun to put the asteroid, then took quick star sights to determine
their exact position. They were within a few miles of perihelion, the
point at which they would be closest to Sol.

Rip tapped gloved fingers on his helmet absently. If they could blast out
of the orbit and drive into the sun.... He estimated the result. A few
miles per second of less speed would let them be pulled so far within the
sun's field of gravity that, within an hour or so, small boats would
venture into space only at their peril.

He reviewed the equipment. They had tubes of rocket fuel, but the tubes
wouldn't give the powerful thrust needed for this job. They had one
atomic bomb. One wasn't enough. Not only must they drive toward the sun,
but also they must keep reserve power to blast free again. If only they
had a pair of nuclear charges!

He called his Planeteers together and outlined the problem. Perhaps
one of them would have an idea. But no useful suggestions were
forth-coming--until Dominico spoke up. "Sir, why don't we make two
bombs from one?"

"I wish we could," Rip said. "Do you know how?"

"No, Lieutenant. If we had parts, I could put bombs together. I can take
them apart, but I don't know how to make two out of one." The Italian
Planeteer looked accusingly at Rip. "I thought maybe you knew, sir."

Rip grunted. If they had parts, he could assemble nuclear bombs, too.
Part of his physics training had been concerned with fission and its
various applications. But no one had taught him how to make two bombs
out of one.

The theory behind this particular bomb design was simple. Two or more
correctly sized pieces of plutonium or uranium isotope, when brought
together, formed what was known as a critical mass, which would fission.
The fissioning released energy and produced the explosion.

But there was a wide gap between theory and practice. A nuclear bomb was
actually pretty complicated. It had to be complicated to keep the pieces
of the fissionable material apart until a chemical explosion drove them
together fast and hard enough to create a fission explosion. If the
pieces weren't brought together rapidly enough, the mass would fission
in a slow chain reaction with no explosion.

Rip was trained in scientific analysis. He tackled the problem logically,
considering the design of a nuclear bomb and the reasons for it.

Atomic bombs had to be carried. That meant an outer casing was necessary.
The casing had a lot to do with the design. Suppose no casing were
required? What would be needed?

He took the stylus and computation board from Koa and jotted down the
parts required. First, two or more pieces of plutonium large enough to
form a critical mass. Second, a neutron source--the type of radioactivity
that produced neutrons--to accelerate the reaction. Third, some kind of
neutron reflector. And fourth, explosive to drive the pieces together.

Did they have all those items? He checked them off. Their single five KT
bomb contained at least enough plutonium for two critical masses, if
brought together inside a good neutron reflector. Each mass should give
about a two kiloton explosion. And they did have a good neutron
reflector--nuclite. There wasn't anything better.

"What have we got for a neutron source?" he asked aloud. He was really
asking himself, but he got a quick answer from Koa.

"Sir, some of the stuff left in the craters from the other explosions
gives off neutrons."

"You're right," Rip agreed instantly. A small piece from one of the
craters, when combined with half of the neutron source in the bomb,
should be enough. As for the explosive, they had exploding heads on their
attack rockets.

In other words, he had what he needed--except for a method of putting all
the pieces together to create a bomb.

If only they had a tube of some sort that would withstand the chemical
explosion--the one that brought the critical mass together!

He told the Planeteers what he had been thinking, then asked, "Any ideas
for a tube?"

"How about a tube from the snapper-boat?" Santos suggested.

Rip shook his head. "Not strong enough. They're designed to withstand the
slow push of rocket fuel, not the fast rap of an explosion. When I say
slow, I mean slow-burning when compared with explosive. Any more ideas?"

Kemp, the expert torchman, said, "Sir, I can burn you a tube into the
asteroid."

Rip grabbed the Planeteer so hard they both floated upward. "Kemp, that's
wonderful! That's it!" The details took form in his mind even as he
called orders. "Dominico, tear down that bomb. Santos, remove two heads
from your rockets and wire them to explode on electrical impulse. Kemp,
we'll want the tube just a fraction of an inch wider than a rocket head.
Get your torch ready."

He took the stylus and began calculating. He talked as he worked, telling
the Planeteers exactly what they were up against. "I'm figuring out where
to put the charge so it will do the most good, but my data isn't
complete. If our homemade bomb goes off, I don't know exactly how much
power it will give. If it gives too much, we'll be driven so close to the
sun we'll never get free of its gravity."

Bradshaw, the English Planeteer, said mildly, "Don't worry, Lieutenant.
If it isn't the solar frying pan, it's Connie fire."

A chorus of agreement came from the other Planeteers. "What a crew!" Rip
thought. "What a great gang of space pirates!"

He finished his calculations and found the exact place where Kemp would
cut. A few feet away from the spot was a thick pyramid of thorium. That
would do, and they could cut into it horizontally instead of drilling
straight down. He pointed to it. "Let's have a hole straight in for six
feet. And keep it straight, Kemp. Allow enough room for a lining of
nuclite. Koa, cut a sheet of nuclite to size."

Kemp's torch already was slicing into the metal. Rip asked, "Can you weld
with that thing, Kemp?"

"Just show me what you want, sir."

"Good." Rip motioned to Trudeau. "Frenchy, we'll need a strong rod at
least eight feet long."

The French Planeteer hurried off. Rip consulted his chronometer. Less
than ten minutes had passed since the call from Terra base.

He went over his plan again. It had to work! If it didn't, asteroid and
Planeteers would end up as subatomic particles in the sun's photosphere,
because he had calculated his blast to drive the asteroid past the limit
of safety. It was the only way he could be sure of putting them beyond
danger from Connie landing boats or snapper-boats. The Connie would have
only one chance--to bring his cruiser down.

If he tried that, Rip thought grimly, he would get a surprise. The second
nuclear charge would be set, ready to be fired. The Connie cruiser was
so big that no matter how it pulled up to the asteroid, some part of it
would be close enough to the charge to be blown into space dust. No
cruiser could survive an atomic explosion within five hundred yards, and
the Connie would have to get closer to the nuclear charge than that.

Dominico reported that the bomb had been dismantled. Rip went to it and
examined the raw plutonium, being careful to keep the pieces widely
separated.

This particular bomb design used five pieces of plutonium which were
driven together to form a ball. Rip made a quick estimate. Two were
enough to form a critical mass. He would use two to blast into the sun
and three to blast out again. He would need the extra kick.

There was only one trouble. The pieces were wedge shaped. They would have
to be mounted in thorium in order to keep them rigid. Only Kemp could do
that. They had no cutting tool but the torch.

Santos appeared, carrying a rocket head under each arm. They had wires
wound around them, ready to be attached to an electrical source.

Rip hurried back to where Kemp was at work. The private was using a
cutting nozzle that threw an almost invisible flame five feet long.
In air, the nozzle wouldn't have worked effectively beyond two feet, but
in space it cut right down to the end of the flame. Kemp had his arm
inside the hole and was peering past it as he finished the cut.

"Done, sir," he said, and adjusted the flame to a spout of red fire. He
thrust the torch into the hole and quickly withdrew it as pieces of
thorium flew out. A stream of water hosed into the tube would have worked
the same way.

Rip took a block of plutonium from Dominico and handed it to Kemp. "Cut
a plug and fit this into it. Then cut a second plug for the other piece.
They have to match perfectly, and you can't put them together to try out
the fit. If you do, we'll have fission right here in the open."

Kemp searched and found a piece he had cut in making the tube. It was
perfectly round, ideal for the purpose. He sliced off the inner side
where it tapered to a cone, then, working only by eye estimate, cut out a
hole in which the wedge of fission material would fit. He wasn't off by a
thirty-second of an inch. Skillful application of the torch melted the
thorium around the wedge and sealed it tightly.

Koa was ready with a sheet of nuclite. Trudeau arrived with a pole made
by lashing two crate sticks together.

Rip gave directions as they formed a cylinder of nuclite. Kemp
spot-welded it, and they pushed it into the hole.

Nunez found a small piece of material in one of the earlier craters. It
would provide some neutrons to start the chain reaction. Rip added it to
the front of the plutonium wedge, along with a piece of beryllium from
the bomb, and Kemp welded it in place.

They put the thorium block which contained the plutonium into the hole,
the plutonium facing outward. Trudeau rammed it to the bottom with his
pole. The neutron source, the neutron reflector, and one piece of
fissionable material were in place.

Kemp sliced another round block of thorium out of a nearby crystal and
fitted the second wedge of plutonium into it. At first Rip had worried
about the two pieces of plutonium making a good enough contact, but
Kemp's skillful hand and precision eye removed that worry.

The torchman finished fitting the plutonium and carried the block to the
tube opening. He tried it, removed a slight irregularity with his torch,
then said quietly, "Finished, sir."

Rip took over. He slid the thorium-plutonium block into the tube, took a
rocket head from Santos, and used it to push the block in farther. When
the rocket head was about four inches inside the tube, its wires trailing
out, Rip called Kemp. At his direction, the torchman sliced a thin slot
up the face of the crystal. Rip fitted the wires into it and held them in
place with a small wedge of thorium.

Kemp cut a plug, fitted it into the hole, and welded the seams closed.
The tube was sealed. When electric current fired the rocket head, the
thorium carrying the plutonium wedge would be driven forward to meet the
wedge in the back. And, unless Rip had miscalculated the mass of the two
pieces, they would have their nuclear blast. Rip surveyed the crystal
with some anxiety. It looked right.

Dominico already had rigged the timer from the atomic bomb. He connected
the wires. "Do I set it, sir?"

"Load the communicator, the extra bomb parts, the rocket launcher and
rockets, the cutting equipment, my instruments, and the tubes of fuel,"
Rip ordered. "Leave everything else in the cave."

The Planeteers ran to obey. Rip waited until the landing boat was nearly
loaded, then told Dominico to set the timer for five minutes. He wondered
how they would explode the second charge, since they had only the one
timer left, then forgot about it. Time enough to worry when faced with
the problem.

"I'll take the snapper-boat," he stated. "Santos in the gunner's seat.
Koa in charge in the landing boat. Dowst pilot. Let's show an exhaust."

He fitted himself into the tight pilot seat of the snapper-boat while
Santos climbed in behind. Then, handling the controls with the skill
of long practice, he lifted the tiny fighting rocket above the asteroid
and waited for the landing boat. When it joined up, Rip led the way to
safety. As he cut his exhaust to wait for the explosion, he sighted past
the snapper-boat's nose to the asteroid.

Even though both boats had been careful to match velocity with the
asteroid as closely as possible, the slight difference remaining caused
them to drift sunward. Rip cut his jets in to compensate, and saw Dowst
do the same.

Another few miles toward the sun, and the landing boat wouldn't have the
power to get away from Sol's gravity. A few miles beyond that, even the
powerful little snapper-boat would be caught.

Below, the timer reached zero. A mighty fan of fire shot into space. The
asteroid shuddered from the blast, then swerved gradually, picking up
speed as well as new direction.

Rip swallowed hard. Now they were committed. They would reach a new
perihelion far beyond the limits of safety. _P_ for perihelion and _P_ for
peril. In this case, they were the same thing!



CHAPTER FOURTEEN

Between Two Fires


Back on the asteroid, the Planeteers started laying the second atomic
charge. Rip selected the spot, found a nearby crystal that would serve to
house the bomb, and Kemp started cutting.

The Planeteers knew what to do now, and the work went rapidly. Rip kept
an eye on his chronometer. According to the message from Terra base, he
had about fifteen minutes before the Consops cruiser arrived.

"We have one advantage we didn't have back in the asteroid belt," he
remarked to Koa. "Back there they could have landed anywhere on the
rock. Now they have to stick to the dark side. Snapper-boats could last
on the sun side, but men in ordinary space suits couldn't."

"That's good," Koa agreed. "We have only one side to defend. Why don't we
put the rocket launcher right in the middle of the dark side?"

"Go ahead. And have all men check their pistols and knives. We don't know
what's likely to happen when that Connie flames in."

Rip walked over to the communicator and plugged his suit into the
circuit. "This is the asteroid calling Terra base. Over."

"This is Terra base. Go ahead, Foster. How are you doing?"

"If you need anything cooked, send it to us," Rip replied. "We have heat
enough to cook anything, including tungsten alloy." He explained briefly
what action they had taken.

A new voice came on the communicator. "Foster, this is Colonel Stevens."

Rip responded swiftly, "Yes, sir!" Stevens was the top Planeteer,
commanding officer of all the Special Order Squadrons.

"We've piped this circuit into every channel in the system," the colonel
said. "Every Planeteer in the Squadrons is listening and rooting for you.
Is there anything we can do?"

"Yes, sir," Rip replied. "Do you know if Terra base has been plotting our
course this far?"

There was a brief silence, then the colonel answered, "Yes, Foster. We
have a complete track from the time you started showing on the Terra
screens, about halfway between the orbits of Mars and Earth."

"Did you just get our change of direction?"

"Yes. We're following you on the screens."

"Then, sir, I'd appreciate it if you'd put the calculators to work and
make a time-distance plot for the next few hours. The blast we're saving
to push to escape velocity is about three kilotons. Let us know the last
moment when we can fire."

"You will have it within fifteen minutes. Anything else, Foster?"

"Nothing else I can think of, sir."

"Then, good luck. We'll be standing by."

"Yes, sir. Foster off."

Rip disconnected and turned up his helmet communicator, repeating the
conversation to his men. Koa came and stood beside him. "Lieutenant,
how do we set off this next charge?"

There was only one way. When the time came to blast, they would be too
close to the sun to take to the boats. The blast had to be set off
from the asteroid.

"We'll get underground as far away from the bomb as we can," Rip said. He
surveyed the dark side, which was rapidly growing less dark. "I think the
second crater will do. Kemp can square it off on the side toward the
blast to give us a vertical wall to hide behind."

Koa looked doubtful. "Plenty of radiation left in those holes, sir."

Rip grinned mirthlessly. "Radiation is the least of our problems. I'd
rather get an overdose of gamma then get blasted into space."

A yell rang in his helmet. "Here comes the Connie!"

Rip looked up, startled. The Consops cruiser passed directly overhead,
about ten miles away. It was decelerating rapidly. Rip wondered why they
hadn't spotted it earlier, then realized the Connie had come from the
direction of the hot side.

The enemy cruiser was probably the same one that had attacked them
before. He must have lain in wait for days, keeping between the sun
and Terra. That way, the screens wouldn't pick him up, since very few
observatories scanned the sun with regularity. To the observatories,
the cruiser would have been only a tiny speck, too small to be noticed.
Or, if they had noticed it, the astronomers probably decided it was just
a very tiny sunspot.

The Planeteers worked with increased speed. Kemp welded the final plug
into place, then hurried to the crater from which they would set off
the charge. Dominico and Dowst connected wires from the rocket head to
a reel of wire and rolled it toward the crater. Nunez got a hand-driven
dynamo from the supplies and tested it for use in setting off the charge.
Santos stood by the rocket launcher, with Pederson ready to put another
rack of rockets into the device when necessary.

Rip and Koa watched the Connie cruiser. It decelerated to a stop for a
brief second, then started moving again, with no jets showing.

"That's the sun pulling," Rip said exultantly.

"They'll have to keep blasting to maintain position."

The Consops commander didn't wait to trim ship against the sun's drag.
His air locks opened, clearly visible to Rip and Koa because that side of
the cruiser was brilliant with sunlight. Ten snapper-boats sped forth.
Rip was certain now that this was the enemy cruiser they had fought off
back in the asteroid belt. Two Connie snapper-boats had been destroyed in
that clash, which explained why the commander was sending out only ten
boats instead of a full quota of twelve.

The squadron instantly formed a V, like a strange space letter made up of
globes. The sun's gravity pulled at them, dragging them off course. Rip
watched as flames poured from their stern tubes. They were firing full
speed ahead, but the drag of the sun distorted their line of flight into
a great arc.

Rip saw the strategy instantly. The Connie commander knew the situation
exactly, and he was staking everything on one great gamble, sending his
snapper-boats to land on the asteroid--to crash-land if necessary.

The asteroid was so close to the sun that even the powerful fighting
rockets would use most of their fuel in simply combating its gravity.

"All hands stand by to repel Connies," Rip shouted, and he drew his
pistol. He looked into the magazine, saw that the clip was full, and
then charged the weapon.

Santos was crouched over the rocket launcher, his space gloves working
rapidly as he kept the rockets pointed at the enemy.

Rip called, "Santos, fire at will."

The Planeteers formed a skirmish line which pivoted on the launcher. Only
Kemp remained at work. His torch flared, slicing through the thorium as
he prepared their firing position.

The atomic charge was ready. The wires had been laid up to the rim of the
crater in which Kemp worked, and the dynamo was attached.

Rip was everywhere, checking on the launcher, on Kemp, on the pistols of
his men. And Santos, hunched over his illuminated sight, watched the
Connie snapper-boats draw near.

"Here we go," the corporal muttered. He pressed the trigger.

The first rocket sped outward in a sweeping curve, and for a moment Rip
opened his mouth to yell at Santos. The sun's gravity affected the attack
rockets, too! Then he saw that the corporal had allowed for the sun's
pull.

The rocket curved into the squadron of on-coming boats, and they all
tried to dodge at once. Two of them met in a sideways crash, then a third
staggered as its stern globe flared and exploded. Santos had scored a
hit!

Rip called, "Good shooting!"

The corporal's reply was rueful. "Sir, that wasn't the one I aimed at.
The sun's pull is worse than I figured."

The damaged snapper-boat instantly blasted from its nose tubes,
decelerated, and went into reverse, flipping through space crabwise as it
tried to regain the safety of the cruiser. The two boats that had crashed
while trying to dodge were blasting in great spurts of flame, following
the example of their damaged companion.

"Seven left," Rip called, and another rocket flashed on its way. He
followed its trail as it curved away from the asteroid and into the
squadron. Its proximity fuse detonated in the exhaust of a Connie boat,
blowing the tube out of position. The boat yawed wildly, cut its stern
tubes, and blasted to a stop from the bow tube. Then it, too, started
backward toward the cruiser. Six left!

Flame blossomed a few yards from Rip. He was picked up bodily and flung
into space, whirling end over end. Koa's voice rang in his helmet.

"Watch it! They're firing back!"

Rip tugged frantically at an air bottle in his belt. He pulled it out and
used it to whirl him upright again; then its air blast drove him back to
the surface of the asteroid. Sweat poured from his forehead, and the suit
ventilator whined as it picked up the extra moisture. Great Cosmos! That
was close!

Santos fired again, twice, in rapid succession. The Connie snapper-boats
scattered as the proximity fuses produced flowers of fire among them. Two
near misses, but they threw the enemy off course. Rip watched tensely as
the boats fought to regain their course. He knew asteroid, cruiser, and
boats were speeding toward the sun at close to fifty miles a second,
and the drag was getting terrific. The Connies knew it, too.

There was an exultant yell from the Planeteers as two of the boats gave
up and turned back, using full power to regain the safety of the mother
ship. Four left!

Santos scored a direct hit on the nose of the nearest one, but
its momentum drove it to within a few yards of the asteroid. Five
space-suited figures erupted from it, holding hand propulsion units,
tubes of rocket fuel used for hand combat in empty space.

The Connies lit their propulsion tubes and drove feet first for the
asteroid. The Planeteers estimated where the enemy would land, and
they were there waiting, with aimed handguns. The Connies had their hands
over their heads, holding the propulsion tubes. They took one look at the
gleaming Planeteer guns, and their hands stayed upright.

The Planeteers lashed the Connies' hands behind them with their own
safety lines and, at Rip's orders, dumped all but one of them into the
crater where Kemp was just finishing his cutting.

Three snapper-boats remained. Rip watched, holding tightly to the arm of
the Connie he had kept at his side. The man wore the insignia of an
officer.

The remaining snapper-boats were going to make it. Santos threw rockets
among them and scored hits, but the boats kept coming. The Connies were
too far away from the cruiser to return, and they knew it. Getting to the
asteroid was their only chance.

Rip called, "Santos! Cease fire. Set the launcher for ground level. Let
them land, but don't fire until I give the word."

He put his helmet against his prisoner's for direct communication. "You
speak English?"

The man shouted back, "Yes."

"Good. We're going to let your friends land. As soon as they do, I want
you to yell to them. Say we have assault rockets trained on them. Tell
them to surrender, or they'll be killed in their tracks. Got that?"

The Connie replied, "Suppose I refuse?"

Rip put his space knife against the man's stomach. "Then we'll get them
with rockets. But you won't care, because you won't know it."

The truth was that Santos couldn't hope to get them all with his rockets.
They might overcome the Connies in hand-to-hand fighting, but there would
be a cost to pay in Planeteer casualties. Rip hoped the Connie wouldn't
call his bluff, because that's all it was. He couldn't use a space knife
on an unarmed prisoner.

The Connie didn't know that. In Rip's place he would have no compunctions
about using the knife, so instead of calling Rip's bluff, he agreed.

The snapper-boats blew their front tubes, decelerating, and squashed down
to the asteroid in a roar of exhaust flames, sending the Planeteers
running out of the way. Rip thrust harder with his space knife and
yelled, "Tell them!"

The Connie officer nodded. "Turn up my communicator."

Rip turned it on full, and the Connie barked quick instructions. The
exhausts died, and five men filed out of each boat, with hands held high.
Rip blew a drop of perspiration from the tip of his nose. Empty space!
It was a good thing Connie morale was bad. The enemy's willingness to
surrender had saved them a costly fight.

The Planeteers rounded up the prisoners and secured them, while Rip took
an anxious look at the communicator. It was about time he heard from
Terra base.

The light was glowing. For all he knew, it might have been glowing for
many minutes. He plugged into the circuit.

"This is Foster on the asteroid."

"Terra base to Foster. Listen. You will reach optimum position on the
time-distance curve at twenty-three-oh-six."

"Got it. We will reach optimum position at twenty-three-oh-six." He
looked at his chronometer, and his pulse stopped. It was 22:58! They
had just eight minutes before the sun caught them forever, atomic blast
or no!

And the Connie cruiser was still overhead, with no friendly cruisers in
sight. He looked up, white-faced. Not only was the Connie still there,
but its main air lock was sliding open to disclose a new danger.

In the opening, ready to launch, an assault boat waited. The assault
boats were something only the Connies used. They were about four times
the size of a snapper-boat, less maneuverable but more powerful. They
carried twenty men and a pair of guided missiles with atomic warheads!



CHAPTER FIFTEEN

The Rocketeers


Rip ran for the snapper-boat, feet moving as rapidly as lack of gravity
would permit. He called instructions. "Santos! Turn the launcher over to
Pederson and come with me. Koa, take over. Start throwing rockets at that
boat, and don't stop until you run out of ammunition."

He reached the snapper-boat and squeezed in, Santos close behind him. As
he strapped himself into the seat he called, "Koa! Get this, and get it
straight. At twenty-three-oh-five, fire the bomb. Fire it whether I'm
back or not."

Koa replied, "Got it, sir."

That would give the Planeteers a minute's leeway. Not much of a safety
margin, especially when he wasn't sure how much power the atomic charge
would produce.

He plugged into the snapper-boat's communicator and called, "Ready,
Santos?"

"Ready, Lieutenant."

He braced himself against acceleration and flipped the speed control to
full power. The fighting rocket rammed out from the asteroid, snapping
him back against the seat. He made a quick check. Gunsight on, fuel tanks
almost full, propulsion tubes racked handy to his hand.

They drove toward the enemy cruiser at top speed, swerving in a great arc
as the sun pulled at them. The enemy's big boat was out of the ship, its
jets firing.

Rip leaned over his illuminated gunsight. The boat showed up clearly, the
rings of the sight framing it. He estimated distance and the pull of the
sun, then squeezed the trigger on the speed control handle. The cannon up
in the nose spat fire. He watched tensely and saw the charge explode on
the hull of the Connie cruiser. He had underestimated the sun's drag. He
compensated and tried again.

He missed. Now that he was closer and the charge had less distance to
travel, he had overestimated the sun's effect. He gritted his teeth.
The next shot would be at close range.

The fighting rocket closed space, and the landing boat loomed large in
the sight. He fired again, and the shot blew metal loose from the top of
the boat's hull. A hit, but not good enough. He leaned over the sight to
fire again, but before he had sighted, an explosion blew the assault boat
completely around.

Koa and Pederson had scored a hit from the asteroid!

The big boat fired its side jets and spun around on course again. Flame
bloomed from its side as Connie gunners tried to get the range on the
snapper-boat.

Rip was within reach now. He fired at point-blank range and flashed over
the boat as its front end exploded. Santos, firing from the rear, hit it
again.

Rip threw the rocket into a turn that rammed him against the top of his
harness. He steadied on a line with the crippled Connie craft. It was
hard hit. The bow jets flickered fitfully, and the stern tubes were dead.
He sighted, fired. A charge hit the boat aft and blew its stern tubes off
completely.

And at the same moment, a Connie gunner got a perfect bead on the
snapper-boat.

Space blew up in Rip's face. The snapper-boat slewed wildly as the Connie
shot took effect. Rip worked his controls frantically, trying to
straighten the rocket out more by instinct than anything else.

His eyes recovered from the blinding flash, and he gulped as he saw the
raw, twisted metal where the boat's nose had been. He managed to correct
the boat's twisting by using the stern tubes, but he lost full control of
the ship.

For a moment panic gripped him. Without full control he couldn't get back
to the asteroid! Then he forced himself to calm down. He sized up the
situation. They were still underway, the stern tubes pushing, but their
trajectory would take them right under the crippled Connie boat.

There was nothing he could do but pass close to the Connie. The enemy
gunners would fire, but he had to take his chances. He looked down at the
asteroid and saw an orange trail as Koa launched another rocket.

The shot from the asteroid ticked the bottom of the Connie boat and
exploded. The Connie rolled violently. Tubes flared as the pilot fought
to correct the roll. He slowed the spinning as Rip and Santos passed,
just long enough for a Connie gunner to get in a final shot.

The shell struck directly under Rip. He felt himself pushed violently
upward, and, at the same moment, he reacted--by hunch and not by reason.
He rammed the controls full ahead, and the dying rocket cut space,
curving slowly as flaming fuel spurted from the ruptured tanks.

Rip yelled, "Santos! You all right?"

"I think so. Lieutenant, we're on fire!"

"I know it. Get ready to abandon ship."

When the main mass of fuel caught, the rocket would become an inferno.
Rip smashed at the escape hatch above his head, grabbed propulsion tubes
from the rack, and called, "Now!"

He pulled the release on his harness, stood up on the seat, and thrust
with all his leg power. He catapulted out of the burning snapper-boat
into space.

Santos followed a second later, and the crippled rocket twisted wildly
under the two Planeteers.

"Don't use the propulsion tubes," Rip called. "Slow down with your air
bottles." He thrust the tubes into his belt, found his air bottles, and
pointed two of them in the direction they had been traveling. He wanted
to come to a stop, to let the wild snapper-boat get away from them.

The compressed-air bottles did the trick. He and Santos slowed down as
the little jets overcame the inertia that was taking them along with the
burning boat. The boat was spiraling now, burning freely. It moved away
from them, its stern jets still firing weakly.

Rip took a look toward the enemy cruiser. The assault boat was no longer
showing an exhaust. Instead, it was being dragged rapidly away from the
Connie cruiser by the pull of the sun. At least it was hit in time to
prevent launching of the atomic guided missiles. Or, he thought, perhaps
the enemy had never intended using them. The principal effect, besides
killing the Planeteers, would have been to drive the asteroid into the
sun at an even faster rate.

The enemy assault boat was no longer a menace. Its occupants would be
lucky if they succeeded in saving their own lives.

Rip wondered what the Connie cruiser commander would try now. Only one
thing remained, and that was to set the cruiser down on the asteroid.
If the Connie tried, he would arrive at just about the time set for
releasing the nuclear charge. And that would be the end of the
cruiser--and probably of the Planeteers as well.

Santos asked coolly, "Lieutenant, wouldn't you say we're in a sort of bad
spot?"

Rip had been so busy sizing up the situation that he hadn't thought about
his own predicament. Now he looked down and suddenly realized that he was
floating free in space, a considerable distance above the asteroid, and
with only small propulsion tubes for power.

He gasped, "Great space! We're in a mess, Santos."

The corporal asked, still in a calm voice, "How long will it be before
we're dragged into the sun, sir?"

Rip stared. Santos had used the same tone he might have used in asking
for a piece of Venusian _chru_. An officer couldn't be less calm, so
Rip replied in a voice he hoped was casual, "I wouldn't worry, Santos. We
won't know it. The heat will get through our suits long before then."

In fact, the heat should be overloading their ventilating systems
right now. In a few minutes the cooling elements would break down, and
that would be the end. He listened for the accelerated whine as the
ventilating systems struggled under the increased heat load but heard
nothing.

Funny. Had it overloaded and given out already? No, that was impossible.
He would be feeling the heat on his body if that were the case.

He looked for an explanation and realized for the first time that they
weren't in the sunlight at all. They were in darkness. His searching
glance told him they were in the cone of shadow stretching out from
behind the asteroid. The thorium rock was between them and the sun!

His lips moved soundlessly. Maj. Joe Barris had been right. _In a jam,
trust your hunch._ He had acted instinctively, not even thinking as he
used the last full power of the stern tubes to throw them into the shadow
cone.

And he knew in the same moment that it could save their lives. The sun's
pull would only accelerate their fall toward the asteroid. He said
exultantly, "We're staying out of high vac, Santos. Light off a
propulsion tube. Let's get back to the asteroid."

He pulled a tube from his belt, held it above his head, and thumbed the
striker mechanism. The tube flared, pushing downward on his hand.

He held steady and plummeted feet first toward the rock.

Santos was only a few seconds behind him. Rip saw the corporal's tube
flare and knew that everything was all right, at least for the moment,
even though the asteroid was still a long way down.

He looked upward at the Connie cruiser and saw that it was moving. Its
exhaust increased in length and deepened slightly in color as Rip
watched.

Then he saw side jets flare out from the projecting control tubes and
knew the ship was maneuvering. Rip realized suddenly that the cruiser was
going to pick up the crippled assault boat.

He hadn't expected such a humane move, after his first meeting with the
Connie cruiser when the commander had been willing to sacrifice his own
men. This time, however, there was a difference, he saw. The commander
would lose nothing by picking up the assault boat, and he would save a
few men. Rip supposed that manpower meant something, even to Consops.

His propulsion tube reached _Brennschluss_, and for a few moments he
watched, checking his speed and direction. Then, before he lit off
another tube, he checked his chronometer. The illuminated dial registered
23:01. They had just four minutes to get to the asteroid!

He spoke swiftly. "Waste no time in lighting off, Santos. That nuclear
charge goes in four minutes!"

Rip pulled a tube from his belt, held it overhead, and triggered it. His
flight through space speeded up, but he wasn't at all sure they would
make it. He turned up his helmet communicator to full power and called,
"Koa, can you hear me?"

The sergeant major's reply was faint in his helmet. "I hear you weakly.
Do you hear me?"

"Same way," Rip replied. "Get this, Koa. Don't fail to explode that
charge at twenty-three-oh-five. Can you see us?"

The reply was very slightly stronger. "I will explode the charge as
ordered, Lieutenant. We can see a pair of rocket exhausts, but no boats.
Is that you?"

"Yes. We're coming in on propulsion tubes."

Koa waited for a long moment, then asked, "Sir, what if you're not with
us by twenty-three-oh-five?"

"You know the answer," Rip retorted crisply.

Of course Koa knew. The nuclear blast would send Rip and Santos spinning
into outer space, perhaps crippled, burned, or completely irradiated.
But the lives of two men couldn't delay the blast that would save the
lives of eight others, not counting prisoners.

Rip estimated his speed and course and the distance to the asteroid. He
was increasingly sure that they wouldn't make it, and the knowledge was
like the cold of space in his stomach. It would be close but not close
enough. A minute would make all the difference.

For a few heartbeats he almost called Koa and told him to wait that extra
minute, to explode the nuclear charge at 23:06, at the very last second.
But even Planeteer chronometers could be off by a few seconds, and he
couldn't risk it. His men had to be given some leeway.

He surveyed the asteroid. The nuclear charge was on his left side, pretty
close to the sun line. At least he and Santos could angle to the right,
to get as far away as possible.

The edge of the asteroid's shadow was barely visible. That it was visible
at all was due to the minute particles of matter and gas that surrounded
the sun, even millions of miles out into space. He reduced helmet power
and told Santos, "Angle to the right. Get as close to the edge of shadow
as you can without being cooked."

As an afterthought, he asked, "How many tubes do you have?"

"One after this, sir. I had three."

"Save the one you have left."

Rip didn't know yet what use they would be, but it was always a good idea
to have some kind of reserve.

The Connie cruiser was sliding up to the crippled assault boat. Rip took
a quick look, then shifted his hands and angled toward the edge of
shadow. When he was within a few feet, he reversed the direction of the
tube to keep from shooting out into the sunlight. A second or two later
the tube burned out.

Santos was several yards away and slightly above him. Rip saw that the
Planeteer was all right and turned his attention back to the cruiser. It
was close enough to the assault boat to haul it in with grappling hooks.
The hooks emerged and engaged the torn metal of the boat, then drew it
into the waiting port. The massive air door slid closed.

The question was, would the Connie try to set his ship down on the
asteroid? Rip grinned without mirth. Now would be a fine time. His
chronometer showed a minute and a half to blast time.

He took another look at his own situation. He and Santos were getting
close to the asteroid, but there was still over a half mile of Earth
distance to go. They would cover perhaps three-fourths of that distance
before Koa fired the charge.

He had a daring idea. How long could he and Santos last in direct
sunlight? The effect of the sun in the open was powerful enough to
make lead run like water. Their suits could absorb some heat, and the
ventilating system could take care of quite a lot. They might last
as much as three minutes, with luck.

They had to take a risk with the full knowledge that the odds were
against them. But if they didn't take the risk, the blast would push
them outward from the asteroid--into full sunlight. The end result would
be the same.

"We're not going to make it, Santos," he began.

"I know it, sir," Santos replied.

Rip thought anyone with that much coolness and sheer nerve rated some
kind of special treatment. And the young corporal had shown his ability
time and time again. He said, "I should have known you knew, _Sergeant_
Santos. We still have a slight chance. When I give the word, use an air
bottle to push yourself into the sunlight. When I give the word again,
light off your remaining tube."

"Yessir," Santos replied. "Thank you for the promotion. I hope I live to
collect the extra rating."

"Same here," Rip agreed fervently. His eyes were on his chronometer, and
with his free hand he took another air bottle. When the chronometer
registered exactly one minute before blast time, he called, "Now!" He
triggered the bottle and moved from shadow into glaring sunlight. A
slight motion of the bottle turned him so his back was to the sun; then
he used the remaining compressed air to push himself downward along the
edge of shadow. The sun's gravity tugged at him.

He pulled the last tube from his belt and held it ready while he watched
his chronometer creep around. With five seconds to go, he called to
Santos and fired it. Acceleration pushed at him.

In the same moment, the nuclear charge exploded.



CHAPTER SIXTEEN

Ride the Planet!


A mighty hand reached out and shoved Rip, sweeping him through space like
a dust mote. He clutched his propulsion tube with both hands and fought
to hold it steady. He swiveled his head quickly, searching for Santos,
and saw the corporal a dozen rods away.

From the far horizon of the asteroid the incandescent fire of the nuclear
blast stretched into space, turning from silver to orange to red as it
cooled.

Rip knew they had escaped the heat and blast of the explosion, but now
there was a question of how much prompt radiation they had absorbed.
During the first few seconds, a nuclear blast sprayed gamma radiation and
neutrons in all directions. He and Santos certainly had gotten plenty.
But how much? His lower-level colorimeter had long since reached maximum
red, and his high-level dosimeter could be read only on a measuring
device.

Meanwhile, he had other worries. Radiation had no immediate effect. At
worst, it would be a few hours before he felt any symptoms.

As he sized up his position and that of the asteroid, he let out a yell
of triumph. His gamble would succeed! He had estimated that going into
the direct gravity pull of the sun at the proper moment and lighting off
their last tubes would put them into a landing position. The asteroid was
moving rapidly, into a new orbit that would intersect the course he and
Santos were on. He had planned on the asteroid's change of orbit. In a
minute at most they would be back on the rock.

His propulsion tube flared out, and he released it. It would travel along
with him, but his hands would be free.

Then he saw something else. The blast had started the asteroid turning!

He reacted instantly. Turning up his communicator he yelled, "Koa! The
rock is spinning! Cut the prisoners loose, grab the equipment, and run
for it! You'll have to keep running to stay in the shadow. If sunlight
hits those fuel tanks or the rocket tubes, they'll explode!"

Koa replied tersely, "Got it. We're moving."

At least the Connie cruiser couldn't harm them now, Rip thought grimly.
He looked for the cruiser and failed to find it for several seconds. It
had moved. He finally saw its exhausts some distance away.

He forgot his own predicament and grinned. The Connie cruiser had moved,
but not because its commander had wanted to. It had been right in the
path of the nuclear blast and had been literally shoved away.

Then Rip forgot the cruiser. His suit ventilator was whining in the
terrific heat, and his whole body was now bathed in perspiration. The sun
was getting them. It would be only a short time until the ventilator
overloaded and burned out. They had to reach the asteroid before then.
The trouble was that there was nothing further he could do about it. He
had only air bottles left, and their blast was so weak that the effect
wouldn't speed him up much. Nevertheless, he called to Santos and
directed him to use his bottles.

Santos spoke up. "Sir, we're going to make it."

In the same instant, Rip saw that they would land on the dark side. The
asteroid was turning over and over. For a second he had the impression
that he was looking at a turning globe of the earth, the kind used in
elementary school back home. But this gray planet was scarcely bigger
than the giant globe at the Space Council building on Terra.

He knew he was going to hit hard. The way to keep from being hurt was to
turn the vertical energy of his arrival into motion in another direction.
As he swept down to the metal surface he started running, his legs
pumping wildly in space. He hit with a bone-jarring thud, lost his
footing and fell sideways, both hands cradling his helmet. He got to his
feet instantly and looked for Santos.

"You all right, sir?" Santos called anxiously. "I think the others are
over there." He pointed.

"We'll find them," Rip said. His hip hurt like fury from smashing against
the unyielding metal, and the worst part was that he couldn't rub it. The
blow had been strong enough to hurt through the heavy fabric and air
pressure, but his hand wasn't strong enough to compress the suit. Just
the same, he tried.

And while he was trying, he found himself in direct sunlight!

He had forgotten to run. Standing still on the asteroid meant turning
with it, from darkness into sunlight and back again. He yelled at Santos
and legged it out of there, moving in long, gliding steps. He regained
the shadow and kept going.

The first order of business was to stop the rock from turning. Otherwise
they couldn't live on it.

Rip knew that they had only one means of stopping the spin. That was to
use the tubes of rocket fuel left over from correcting the course. They
had three tubes left, but he didn't know if that was enough to do the
job.

Moving rapidly, he and Santos caught up to Koa and the Planeteers.

The Connie prisoners were pretty well bunched up, gliding along like a
herd of fantastic sheep. Their shepherds were Pederson, Nunez, and Dowst.
The three Planeteers had a pistol in each hand. The spares were probably
those taken from prisoners.

The Planeteers were loaded down with equipment. A few Connie prisoners
carried equipment, too.

Trudeau had the rocket launcher and the remaining rockets. Kemp had his
torch and two tanks of oxygen. Bradshaw had tied his safety line to the
squat containers of chemical fuel for the torch and was towing them
behind like strange balloons. The only trouble with that system, Rip
thought, was that Bradshaw could stop, but the fuel would have a tendency
to keep going. Unless the Englishman was skillful, his burden would drag
him off his feet.

Dominico had a tube of rocket fuel under each arm. The Italian was small,
and the tubes were bulky. Each was about ten feet long and two feet in
diameter. With any gravity or air resistance at all, the Italian couldn't
have carried even one.

Santos took the radiation detection instruments and the case with the
astrogation equipment from Koa. Rip greeted his men briefly, then took
his computing board and began figuring. He knew the men were glad he and
Santos had made it. But they kept their greetings short. A spinning
asteroid was no place for long and sentimental speeches.

He remembered the dimensions of the asteroid and its mass. He computed
its inertia, then figured out what it would take to overcome the inertia
of the spin.

The mathematics would have been simpler under normal conditions, but
doing them on the run, trying to watch his step at the same time, made
things a little complicated. He had to hold the board under his arm, run
alongside Santos while the new sergeant held the case open, select the
book he wanted, open it and try to read the tables by his belt light, and
then transfer the data to the board.

His ventilator had quieted down once he got into the darkness, but now it
started whining slightly again because he was sweating profusely. Finally
he figured out the thrust needed to stop the spin. Now all he had to do
was compute how much fuel it would take.

He had figures on the amount of thrust given by the kind of rocket fuel
in the tubes. He also knew how much fuel each tube contained. But the
figures were not in his head. They were on reference sheets.

He collected the data on the fly, slowing down now and then to read
something, until a yell from Santos or Koa warned that the sun line was
creeping close. When he had all data noted on the board, he started his
mathematics. He was right in the middle of a laborious equation when he
stumbled over a thorium crystal. He went headlong, shooting like a rocket
three feet above the ground. His board flew away at a tangent. His stylus
sped out of his glove like a miniature projectile, and the slide rule
clanged against his bubble.

It happened so fast that neither Koa nor Santos had time to grab him. The
action had given him extra speed, and he saw with horror that he was
going to crash into Trudeau. He yelled, "Frenchy! Watch out!" Then he put
both hands before him to protect his helmet. His hands caught the French
Planeteer between the shoulders.



CHAPTER SEVENTEEN

Visitors!


Trudeau held tight to the launcher, but the rocket racks opened and
spilled attack rockets into space. They flew in a dozen different
directions. Trudeau gave vent to his feelings in colorful French.

Koa and Santos laughed so hard they had trouble collecting the scattered
equipment. Rip, slowed by his crash with Trudeau, got his feet under him
again.

When the asteroid turned into the sun, they still had not collected Rip's
stylus and five of the attack rockets. The space pencil was the only
thing that could write on the computing board. It had to be found. "Next
time around," Rip called to the others. He then led the way full speed
ahead until they reached the safety of shadow again.

Rip suspected the stylus was somewhere above the rock and probably
wouldn't return to the surface for some minutes. While he was wondering
what to do, there was a chorus of yells. A rocket sped between the
Planeteers and shot off into space.

"Our own rockets are after us," Trudeau gasped. There hadn't been time
to collect them all after Rip's unwilling attack on the Frenchman had
scattered them. Now the sun was setting them off. Another flashed past,
fortunately over their heads. The sun's heat was causing them to fire
unevenly.

"Three more to go," Koa called. "Watch out!"

Only two went, and they were far enough away to offer no danger.

Santos had been fishing around in the instrument case. Suddenly he
produced another stylus. "It was under the sextant," he explained
triumphantly.

"If we get through this, I'll propose you for ten more stripes," Rip
vowed. "We'll make you the highest ranking sergeant that ever made a
private's life miserable."

Working slowly but more safely, Rip figured that slightly more than two
and a half tubes would do the trick.

Now to fire them. That meant finding a thorium crystal properly placed
and big enough. There were plenty of crystals, so that was no problem.
The next step was for Kemp to cut holes with his torch, so that the
thrust of the rocket fuel would be counter to the direction in which the
asteroid was spinning.

Rip explained to all hands what had to be done. The burden would fall on
Kemp, who would need a helper. Rip took that job himself. He took one
oxygen tank from Kemp. Koa took the other, leaving the torchman with only
his torch.

Then Rip took a container of chemical fuel from Bradshaw. Working while
running, he lashed the two containers together with his safety line. Then
he improvised a rope sling so they could hang on his back.

Kemp, meanwhile, assembled his torch and put the proper cutting nozzle in
place. When he was ready, he moved over to Rip's side and connected the
torch hoses to the tanks the lieutenant carried. Kemp had the torch
mechanism strapped to his own back. It was essentially a high-pressure
pump that drew oxygen and fuel from the tanks and forced them through
the nozzle, under terrific pressure.

When he had finished, he pressed the trigger that started the cutting
torch going. The fuel ignited about a half inch in front of the nozzle.
The nozzle had two holes in it, one for oxygen and the other for fuel.
The holes were placed and angled to keep the flame always a half inch
away, otherwise the nozzle itself would melt.

"How do we work this?" Kemp asked.

"We'll get ahead of the others," Rip explained. "Keep up speed until
we're running at the forward sun line. Then, when the crystal we want
comes around into the shadow, we stop running and work until it spins
back into the sunshine again."

Rip estimated the axis on which the asteroid was spinning and selected
a crystal in the right position. He had to be careful, otherwise their
counterblast might do nothing more than start the gray planet wobbling.

He and Kemp ran ahead of the others. The Planeteers and their prisoners
were running at a speed that kept them right in the middle of the dark
area.

It was like running on a treadmill. The Planeteers were making good
speed, but were actually staying in the same place relative to the sun's
position, keeping the turning asteroid between them and the sun.

Rip and Kemp ran forward until they were right at the sun line. Then they
slowed down, holding position and waiting for the crystal they had chosen
to reach them. As it came across the sun line into darkness, they stopped
running and rode the crystal through the shadow until it reached the sun
again. Then the two Planeteers ran back across the dark zone to meet the
crystal as it came around again. There was only a few minutes' working
time each revolution.

Kemp worked fast, and the first hole deepened. Rip helped as best he
could by pushing away the chunks of thorium that Kemp cut free, but it
was essentially a one-man job.

As Kemp neared the bottom of the first hole, Rip reviewed his plan and
realized he had overlooked something. These weren't nuclear bombs; they
were simple tubes of chemical fuel. The tubes wouldn't destroy the hole
Kemp was cutting.

He reached a quick decision and called Koa to join them. Koa appeared as
Kemp pulled his torch from the hole and started running again to avoid
the sun. Rip and Koa ran right along with him, crossing the dark zone to
meet the crystal as it came around again.

"There's no reason to drill three holes," Rip explained as they ran.
"We'll use one hole for all three charges. They don't have to be fired
all at once."

"How do we fire them?" Koa asked.

"Electrically. Who has the igniters and the hand dynamo?"

"Dowst has the igniters. One of the Connies is carrying the dynamo."

Speaking of the Connies--Rip hadn't seen the Consops cruiser recently. He
looked up, searching for its exhaust, and finally found it, some distance
away.

The Connie commander was stalemated for the time being. He couldn't land
his cruiser on a spinning asteroid, and he had no more boats. Rip thought
he probably was just waiting around for any opportunity that might
present itself.

The Federation cruisers should be arriving. He studied his chronometer.
No, the nearest one, the _Sagittarius_ from Mercury, wasn't due for
another ten minutes or so. He turned up his helmet communicator and
ordered all hands to watch for the exhaust of a nuclear drive cruiser,
then turned it down again and gave Koa instructions.

"Have Trudeau turn his load over to a Connie and collect the igniters and
the dynamo. We'll need wire, too. Who has that?"

"Another Connie."

"Get a reel. Cut off a few hundred feet and connect the dynamo to one end
and an igniter to the other."

The crystal came around again, and Kemp got to work. Rip stood by, again
reviewing all steps. They couldn't afford to make a mistake. He had no
margin for error.

Kemp finished the hole a few seconds before the crystal turned into the
sunlight again. Rip told him to keep the torch going. There might be some
last minute cutting to do. Then the lieutenant hurried off at an angle to
where Dominico was plodding along with the fuel tubes.

Koa had turned the tube he carried over to a Connie. Rip got it and told
Dominico to follow him. Then he angled back across the asteroid to where
Kemp was holding position.

The asteroid turned twice before Koa arrived. He had a coil of wire slung
over his arm, and he carried the dynamo in one hand and an igniter in the
other, the two connected by the wire.

Rip took the igniter. "Uncoil the wire," he directed. "Go to its full
length at right angles to the hole. We have to time this exactly right.
When the crystal comes around again, I'll shove the tube into the hole,
then scurry for cover. When I'm clear I'll yell, and you pump the dynamo.
Dominico and Kemp stay with Koa. Make sure no one is in the way of the
blast."

Koa unreeled the wire, moving away from Rip. The lieutenant pushed the
igniter into one end of the fuel tube and crimped it tightly with his
gloved hand.

Koa and the others were as far away as they could get now, the wire
stretching between them and Rip. Kemp had made sure no one was running
near the line of blast.

Rip watched for the crystal. It would be coming around any second now. He
held the tube with the igniter projecting behind him, ready for the hole
to appear.

Koa's voice echoed in his helmet. "All set, Lieutenant."

The crystal appeared across the sun line and moved toward him. He met it,
slowed his speed, put the end of the tube into the hole, and shoved. Kemp
had allowed enough clearance. The tube slid into place. Rip turned and
angled off as fast as he could glide. When he was far enough away from
the blast line he called, "Fire!"

Koa squeezed the dynamo handle. The machine whined, and current shot
through the wire. A column of orange fire spurted from the crystal.

Rip watched the stars instead of the exhaust. He kept running as it
burned soundlessly. In air, the noise would have deafened him. In airless
space, there was nothing to carry the sound.

The apparent motion of the stars was definitely slowing. The spinning
wouldn't cease entirely, but it would slow down enough to give them more
time to work.

The tube reached _Brennschluss_, and Rip called orders. "Same process.
Get ready to repeat."

While Koa was connecting another igniter to the wire, Rip took a tube
from Dominico. "Take your space knife and saw through the tube you have
left. We'll need about three-fifths of it. Keep both pieces."

Dominico pulled his knife, pressed the release, and the gas capsule shot
the blade out. He got to work.

Koa called that he was ready. Rip took the wired igniter from him and
thrust it into the tube Dominico had given him.

As the crystal came around again, the process was repeated. The hole was
undamaged.

There was more time to get clear because of the asteroid's slower speed.
The second tube slowed the rock even more, so that they had to wait long
minutes while the crystal came around again.

Rip did some estimating. He wanted to be sure the next charge would do
nothing more than slow the asteroid to a stop. If the charge were too
heavy, it would reverse the spin. He didn't want to make a career of
running on the asteroid. He was tired, and he knew his men were getting
weary, too. He could see it in their strides.

He decided it would be best to use a little less fuel rather than a
little more. If the asteroid failed to stop its spin completely, they
could always set off a small charge or two.

"Hold it," he ordered. "We'll use the small end of Dominico's tube and
save the big one."

The fuel was a solid mass, so cutting the tube in two sections caused no
difficulty. Rip pushed the igniter into the small section, seated it in
the hole, and hurried to cover. As he watched the fuel burn, he wondered
why the last nuclear charge had started the spin. He had made a mistake
somewhere. The earlier blasts had been set so they wouldn't cause a spin.
He made a mental note to look at the place where the charge had exploded.

The rocket fuel slowed the asteroid down to a point where it was barely
turning, and Rip was glad he had been cautious. The heavier charge would
have reversed it a little. He directed the placing of a very small charge
and was moving away from it so Koa could set it off when Santos suddenly
yelled, "Sir! The Connie is coming!"

Rip called, "Fire the charge, Koa," then looked up. The Consops cruiser
was moving slowly toward them. The canny Connie had been waiting for
something to happen on the asteroid, Rip guessed. When the spinning
slowed and then stopped, the Connie probably had decided that now was
the time for a final try.

"Where is the communicator?" Rip asked the sergeant major.

"One of the Connies has it."

"Get it. I'll notify Terra base of what happened."

Koa found the Connie with the communicator, tested it to be sure the
prisoner hadn't sabotaged it, and brought it to Rip.

"This is Foster to Terra base. Over."

"Come in, Foster."

Rip explained briefly what had happened and asked, "How is our orbit?
I haven't had time to take sightings."

"You're free of the sun," Terra base answered. "Your orbit will have to
be corrected sometime within the next few hours. The last blast pushed
you off course."

"That's a small matter," Rip stated. "Unless we can think of something
fast, this will be a Connie asteroid by then. The Consops cruiser is
moving in on us. He's careful, because he isn't sure of the situation.
But even at his present speed he'll be here in ten minutes."

"Stand by." Terra base was silent for a few moments, then the voice
replied, "I think we have an answer for you, Foster. Terra base off.
Go ahead, MacFife."

A Scottish burr thick enough to saw boards came out of the communicator.
"Foster, this is MacFife, commander on the _Aquila_. Y'can't see me on
account of I'm on yer sunny side. But, lad, I'm closer to ye than the
Connie. We did it this way to keep the asteroid between us and him. Also,
lad, if ye'll take a look up at Gemini, ye'll see somethin' ye'll like.
Look at Alhena, in the Twins' feet. Then, lad, if ye'll be patient the
while, ye'll have a grandstand seat for a real big show."

Rip tilted his bubble back and stared upward at the constellation of the
Twins. He said softly, "By Gemini!" For there, a half degree south of
the star Alhena, was the clean line of a nuclear cruiser's exhaust. The
_Sagittarius_, out of Mercury, had arrived.

He cut the communicator off for a moment and spoke exultantly to his men.
"Stand easy, you hairy Planeteers. Forget the Connie. He doesn't know it,
but he's caught. He's caught between the Archer and the Eagle!"



CHAPTER EIGHTEEN

Courtesy--With Claws


Sagittarius, constellation of the Archer, and Aquila, constellation of
the Eagle, had given the two Federation patrol cruisers their names. The
Eagle was commanded by a tough Scotsman, and the Archer by a Frenchman.

Commander MacFife spoke through the communicator. "Switch bands to
universal, lad. Me'n Galliene are goin' to talk this Connie into a braw
mess. MacFife off."

Rip guessed that the two cruiser commanders had been in communication
while enroute to the asteroid and had cooked up some kind of plan. He
turned the band switch to the universal frequency with which all
long-range communicators were equipped. Each of the Earth groups had its
own frequency, and so did the Martians and Jovians. But all could meet
and talk on the universal band.

Special scrambling devices prevented eavesdropping on regular
frequencies, so there was no danger that the Connie had overheard the
plan. Rip wondered what it was. He knew the cruisers had to be careful
not to cross the thin line that might lead to war.

The _Sagittarius_ loomed closer, decelerating with a tremendous exhaust.
The Connie couldn't have failed to see it, Rip knew. He was right. The
Consops cruiser suddenly blasted more heavily, rushing in the direction
away from the Federation ship. The direction was toward the asteroid.

At the same moment, the _Aquila_ flashed above the horizon, also
decelerating. The Connie was caught squarely.

A suave voice spoke on the universal band. "This is Federation SCN
_Sagittarius_, calling the Consolidation cruiser near the asteroid.
Please reply."

Rip waited anxiously. The Connie would hear, because every control room
monitored the universal band.

A heavy, reluctant voice replied after a pause of over a minute.

"This is Consolidation cruiser Sixteen. You are breaking the law,
_Sagittarius_. Your missile ports are open, and they are pointing at me.
Close them at once, or I will report this."

The suave voice, with its hint of French accent, replied, "Ah, my friend!
Do not be alarmed. We have had a slight accident to our control circuit,
and the ports are jammed open. We are trying to repair the situation. But
I assure you that we have only the friendliest of intentions."

Rip grinned. This was about the same as a man holding a cocked pistol at
another man's head and assuring him that it was nothing but a nervous arm
that kept the gun so steady.

The Connie demanded, "What do you want?"

The two friendly cruisers were within a few miles of the Connie now, and
their blasts were just strong enough to keep them edging closer, while
still counteracting the sun's pull.

The French spaceman spoke reassuringly. "My friend, we want only
the courtesy of space to which the law entitles us. We have had an
unfortunate accident to our astrogation instruments, and we wish to
come aboard to compare them with yours."

Rip laughed outright. Every cruiser carried at least four sets of
instruments. There was as much chance of all of them being knocked off
scale at once as there was of his biting a cruiser in half with bare
teeth.

MacFife's voice came on the air. "Foster, switch to Federation
frequency."

Rip did so. "This is Foster, Commander."

"Lad, it's a pity for ye to miss the show. I'm sending a boat for ye."

"The sun will get it!" Rip exclaimed.

"Never fear, lad. It won't get this one. Now, switch back to universal
and listen in."

Rip did so in time to catch the Connie commander's voice. "... and I
refuse to believe such a story! Great Cosmos, do you think I am a fool?"

"Of course not," the Frenchman replied. "You are not such a fool as to
refuse a simple request to check our instruments."

The _Sagittarius_ commander was right. Rip understood the strategy.
Equipment sometimes did go out of operation in space, and Connies had
no hesitation in asking Federation cruisers for help, or the other way
around. Such help was always given, because no commander could be
sure when he might need help himself.

"I agree," the Connie commander said with obvious reluctance. "You may
send a boat."

MacFife's Scotch burr broke in. "Federation SCN _Aquila_ to Consolidation
Sixteen. Mister, my instruments are off scale, too. I'll just send them
along to ye, and ye can check them while ye're doing the _Sagittarius_!"

"I object!" the Connie bellowed.

"Come, now," MacFife burred soothingly. "Checking a few instruments won't
hurt ye."

A small rocket exhaust appeared, leaving the _Aquila_. The exhaust grew
rapidly, more rapidly than that of any snapper-boat. Rip watched it,
while keeping his ears tuned to the space conversation.

"Surely sending boats is too much of a nuisance," the French commander
said winningly. "We will come alongside."

"It's a trick," the Connie growled. "You want me to open my valves, and
then your men will board us and try to take over my ship!"

"My friend, you have a suspicious mind," Galliene replied smoothly. "If
you wish, arm your men. Ours will have no weapons. Train launchers on the
valves, so our men will be annihilated before they can board if you see a
single weapon."

This was going a little far, Rip thought, but it was not his affair, and
he didn't know exactly what MacFife and Galliene had in mind.

The _Aquila's_ boat arrived with astonishing speed. Rip saw it flash in
the sunlight and knew he had never seen one like it before. It was a
perfect globe, about twenty feet in diameter. Blast holes covered the
globe at intervals of six feet.

The boat settled to the asteroid, and a new voice called over the helmet
circuit, "Where's Foster? Show an exhaust! We're in a rush."

"Yes, sir."

He hurried to the boat and stood there, bewildered. He didn't know how to
get in.

"Up here," the voice called. He looked up and saw a hatch. He jumped, and
a space-suited figure pulled him inside. The door shut, and the boat
blasted off. Acceleration shoved him backward, but the spaceman snapped a
line to his belt, then motioned him to a seat. Rip pulled himself up the
line and got into the seat, snapping the harness in place.

"I'm Hawkins, senior space officer," the spaceman said. "Welcome, Foster.
We've been losing weight wondering if we'd get here in time."

"I was never so glad to see spacemen in my life," Rip said truthfully.
"What kind of craft is this, sir?"

"Experimental," the space officer answered. "It has a number, but we call
it the ball-bat because it's shaped like a ball and goes like a bat. We
were about to take off for some test runs around the space platform when
we got a hurry call to come here. The _Aquila_ has two of these. If they
prove out, they'll replace the snapper-boats. More power, greater
maneuverability, heavier weapons, and they carry more men."

Rip looked out through the port and saw the two Federation cruisers
closing in on the Connie. Apparently the Connie commander had agreed
to let the cruisers come alongside.

The ball-bat blasted to the _Aquila_, paused at an open port, then slid
inside. The valve was shut before Rip could unbuckle his harness. Air
flooded into the chamber, and the lights flicked on. The space officer
gave Rip a hand out of the harness, and the young Planeteer went through
the hatch to the deck.

The inner valve opened, and a lean, sandy-haired officer in space blue,
with the insignia of a commander, stepped through. Grinning, he hurried
to Rip's side and twisted his bubble, lifting it off.

"Hurry, lad," he greeted Rip. "I'm MacFife. Get out of that suit quick,
because ye don't want to miss what's aboot to happen." With his own hands
he unlocked the complicated belt with its gadgets and equipment.

Rip slipped the upper part over his head and stepped out of the bottom.
"Thanks, Commander. I'm one grateful Planeteer, believe me!"

"Come on. We'll hurry right across ship to the opposite valve. Lad,
I've a son in the Planeteers, and he's just about your own age. He's
on Ganymede. He and the others will be proud of what ye've done."

MacFife was pulling himself along rapidly by the convenient handholds.
Rip followed, his breathing a little rapid in the heavier air of the
ship. He followed the Scottish commander through the maze of passages
that crossed the ship. They stopped at a valve where spacemen were
waiting. With them was an officer who carried a big case.

"The instruments," MacFife said, pointing. "We've tinkered with them a
bit, just to make it look real."

"But why do you want to board the Connie?"

MacFife's eye closed in a wink. "Ye'll see."

There was a slight bump as the cruiser touched the Connie. The waiting
group recovered balance and faced the valve. Rip knew that spacemen in
the inner lock were making fast to the Connie, setting up the airtight
seal.

It wasn't long before a bell sounded, and a spaceman opened the inner
valve. Two men in space suits were waiting, and beyond them the outer
valve was joined by a tube to the outer valve of the Connie ship. Rip
stared at the Connie spacemen in their red tunics and gray trousers.
One, an officer with two pistols in his belt, stepped forward.

Rip noted that the other Connies were heavy with weapons, too. None of
his group had any.

"I'm the commander," the scowling Connie said. "Bring your instruments
in. We'll check them; then you get out."

"Ye're no verra friendly," MacFife said, his burr even more pronounced.
He led Rip and the officer with the instruments into the Connie ship.

A handsome Federation spaceman with a moustache, the first Rip had ever
seen, stepped into the room from a passageway on the opposite side. The
spaceman bowed with exquisite grace. "I have the honor of making myself
known," he proclaimed. "Commander Rémy Galliene of the _Sagittarius_."

The Connie commander grunted. He was afraid, Rip realized. The Connie
suspected a trick, and he had no idea what it might be.

Galliene saw Rip's black uniform and hurried to shake his hand. "So
this is the young lieutenant who is responsible! Lieutenant, today the
spacemen honor the Planeteers because of you. Most days we fight each
other, but today we fight together, eh? I am glad to meet you!"

"And I'm glad to meet you, sir," Rip returned. He liked the twinkle in
the Frenchman's eye. He would have given a lot to know what scheme
Galliene and MacFife had cooked up.

The Connie had overheard Galliene's greeting. He glared at Rip. The
Frenchman saw the look and smiled happily. "Ah, you do not know each
other? Commander, I have the honor to make known Lieutenant Foster of the
Federation Special Order Squadrons. He is in command on the asteroid."

The Connie blurted, "So! I send boats to help you, and you fire on them!"

So that was to be the Consops story! Rip thought quickly, then held
up his hand in a shocked gesture that would have done credit to the
Frenchman. "Oh, no, Commander! You misunderstand. We had no way of
communicating by radio, so I did the only thing we could do. I fired
rockets as a warning. We didn't want your boats to get caught in a
nuclear explosion."

He shrugged. "It was very unlucky for us that the sun threw my gunner's
aim off and he hit your boats--quite by accident."

MacFife coughed to cover up a chuckle. Galliene hid a smile by stroking
his moustache.

The Connie commander growled, "And I suppose it was accident that you
took my men prisoner?"

"Prisoner?" Rip looked bewildered. "We took no prisoners. When your boats
arrived, the men asked if they might not join us. They claimed refuge,
which we had to give them under interplanetary law."

"I will take them back," the Connie stated.

"You will not," Galliene replied with equal positiveness. "The law is
very clear, my friend. Your men may return willingly, but you cannot
force them. When we reach Terra we will give them a choice. Those who
wish to return to the Consolidation will be given transportation to the
nearest border."

The Connie commander motioned to a heavily armed officer. "Take their
instruments. Check them quickly." He put his lips together in a straight
line and stared at the Federation men. They stared back with equal
coldness.

The minutes ticked by. Rip wondered again what kind of plan MacFife and
Galliene had.

Additional minutes passed, and the officer returned with the cases.
Wordlessly he handed them to Galliene and MacFife. The Connie commander
snapped, "There. Now get out of my ship."

Galliene bowed. "You have been a most courteous and gracious host,"
he said. "Your conversation has been stimulating, inspiring, and
informative. Our profound thanks."

He shook hands with Rip and MacFife, bowed to the Connie commander again,
and went out the way he had come. There wasn't anything to say after the
Frenchman's sarcastic farewell speech. MacFife, Rip, and the officer with
the instruments went back through the valves into their own ship.

Once inside, MacFife called, "Come with me. Hurry." He led the way
through passages and up ladders, to the very top of the ship, to the
hatch where the astrogators took their star sights. The protective shield
of nuclite had been rolled back, and they could see into space through
the clear-vision port.

Rip and MacFife hurried to the side where they were connected to the
Connie. Rip looked down along the length of the ship. The valve
connection was in the middle of each ship, at the point of greatest
diameter. From that point each ship grew more slender.

MacFife pointed to the Connie's nose. Projecting from it like great horns
were the ship's steering tubes. Unlike the Federation cruiser, which
blasted steam through internal tubes that did not project, the Connie
used chemical fuel.

"Watch," MacFife said.

There were similar tubes on the Connie's stern, Rip knew. He wondered
what they had to do with the plan.

MacFife walked to a wall communicator. "Follow instructions."

He turned to Rip. "Remember, lad, the _Sagittarius_ is on the other side
of the Connie, about to do the same thing."

Rip waited in silence, wondering.

Then the voice horn called. "Valve closed!"

A second voice yelled, "Blast!"

A tremor jarred its way through the entire ship, making the deck throb
under Rip's feet. He saw that the ship's nose had swung away from the
Connie. What in space--

"Blast!"

The nose swung into the Connie again, with a jar that sent Rip sliding
into the clear plastic of the astrodome. His nose jammed into the
plastic, but he didn't even wince, because he saw the Connie cruiser's
steering tubes buckle under the _Aquila's_ sudden shove.

And suddenly the picture was clear. The two Federation cruisers hadn't
cared about getting into the Connie ship. They had only wanted an excuse
to tie up to it so they could do what had just been done.

They had sheared off the enemy's steering tubes, first at the stern, then
at the bow, leaving him helpless, able to go only forward or back in the
direction in which he happened to be pointing!

MacFife had a broad grin on his face. As Rip started to speak, he held up
his hand and pointed at a wall speaker.

The Connie commander came on the circuit. He screamed, "You planned that!
You--you--"

Galliene's voice spoke soothingly. "But my dear commander! How can I
apologize? Believe me, the man responsible will be reward--I mean, the
man responsible will be disciplined. You may rest assured of it. How
unfortunate! I am overcome with shame."

MacFife picked up a microphone. "Same here, Connie. A terrible accident.
Aye, the man who did it will hear from me."

"It was no accident," the Connie screamed.

"Ah," Galliene replied, "but you cannot prove otherwise. Commander, do
you realize what this means? You are helpless. Interplanetary law says
that a helpless space ship must be salvaged and taken in tow by the
nearest cruiser, no matter what its nationality. We will do this jointly,
the _Aquila_ and the _Sagittarius_. We will take turns towing you, my
friend. We will haul you to Terra--like any other piece of space junk."

MacFife could remain quiet no longer. "Yes, mister. And that's no' the
end o' it. We will collect the salvage fee. One half the value of the
salvaged vessel. Aye! My men will like that, since we share and share
alike on salvage. Now, put out a cable from your nose tube. I'll take ye
in tow first."

He cut the communicator off and met Rip's grin.

The two spacemen had figured out the one way to repay the Connie for his
attempts on the asteroid. They couldn't fire on him, but they could fake
an accident that would cripple him and cost Consops millions of dollars
in salvage fees.

Nor would Consops refuse to pay. Salvage law was clear. Whoever performed
the salvage was not required to turn the ship back to its owners until
the fee had been paid.

And there was another angle. The cruisers would tow the Connie into
the Federation spaceport in New Mexico. If past experience was any
indication, the Connie would lose about half its crew, perhaps more.
They would claim sanctuary in the Federation.

Rip shook hands solemnly with the grinning Scotchman. It would be a long
time before Consops tried piracy again.

"We'll be back at our family fight again tomorrow," MacFife said, "but
today we celebrate together. Ah, lad, this is pure joy to me. I've had
a score to settle with yon Connies for years. Now I've done it."

He put an arm around Rip's shoulders. "While I'm in a givin' mood, which
is not the way of us Scots, is there anything ye'd like?"

Rip could think of only one thing. "A hot shower. For me and my men. And
will you take the prisoners off our hands?"

"Yes to both. Anything else?"

"We'll need some rocket fuel. Terra says we have to correct course. Also,
we'll need a nuclear charge to throw us into a braking ellipse. And we
need a new landing boat. The sun baked the equipment out of ours."

MacFife nodded. "So be it. I'll send men to the asteroid to bring back
the prisoners and your Planeteers." He smiled. "We'll let yon rock go by
itself while hot showers and a good meal are had by all. Ye've earned it,
lad."

Rip started to thank the Scot, but his stomach suddenly turned over, and
black dizziness flooded in on him. He heard MacFife's sudden exclamation,
felt hands on him.

White light blinded him. He shook his head and tried to keep his stomach
from acting up. A voice asked, "Were you shielded from those nuclear
blasts?"

"No," he said past a constricted throat. "Not from the last. We got some
prompt radiation."

"When was that? The exact time?"

Rip tried to remember. He felt horrible. "It was twenty-three-oh-five."

"Bad," the voice said. "He must have taken enough roentgens of gamma and
neutrons to reach or exceed the median-lethal dose."

Rip found his voice again. "Santos," he said urgently. "On the asteroid.
He got it, too. The rest were shielded."

MacFife snapped orders. The ball-bat would have Santos in the ship within
minutes. Being sick in a space suit was about the most unpleasant thing
that could happen.

A hypospray tingled against Rip's arm. The drug penetrated, caught
a quick lift to all parts of his body through the bloodstream.
Consciousness slid away.



CHAPTER NINETEEN

Spacefall


Rip was never more eloquent. He argued, he begged, and he wheedled.

The _Aquila's_ chief physician listened with polite interest, but he
shook his head. "Lieutenant, you simply are not aware of the close call
you've had. Another two hours without treatment, and we might not have
been able to save you."

"I appreciate that," Rip assured him. "But I'm fine now, sir."

"You are not fine. You are anything but fine. We've loaded you with
antibiotics and blood cell regenerator, and we've given you a total
transfusion. You feel fine, but you're not."

The doctor looked at Rip's red hair. "That's a fine thatch of hair you
have. In a week or two it will be gone, and you'll have no more hair
than an egg. A well person doesn't lose hair. Your head will shine like
a space helmet."

The ship's radiation safety officer had put both Rip's and Santos'
dosimeters into his measuring equipment. They had taken over a hundred
roentgens of hard radiation above the tolerance limit. This was the
result of being caught unshielded when the last nuclear charge went
off.

"Sir," Rip pleaded, "you can load us with suppressives. It's only a few
days more before we reach Terra. You can keep us going until then. We'll
both turn in for full treatment as soon as we get to the space platform.
But we have to finish the job; can't you see that, sir?"

The doctor shook his head. "You're a fool, even for a Planeteer. Before
you get over this, you'll be sicker than you've ever been. You have a
month in bed waiting for you. If I let you go back to the asteroid, I'll
only be delaying the time when you start full treatment."

"But the delay won't hurt if you inject us with suppressives, will it?"
Rip asked quickly. "Don't they keep the sickness checked?"

"Yes, for a maximum of about ten days. Then they no longer have
sufficient effect, and you come down with it."

"But it won't take ten days," Rip pointed out. "It will only take a
couple, and it won't hurt us."

MacFife had arrived to hear the last exchange. He nodded sympathetically.
"Doctor, I can appreciate how the lad feels. He started something, and he
wants to finish it. If y'can let him, safely, I think ye should."

The doctor shrugged. "I can let him. There's a nine to one chance it will
do him no harm. But the one chance is what I don't like."

"I'll know it if the suppressives start to wear off, won't I?" Rip asked.

"You certainly will. You'll get weaker rapidly."

"How rapidly?"

"Perhaps six hours. Perhaps more."

Rip nodded. "That's what I thought. Doctor, we're less than six hours
from Terra by ship. If the stuff wears off, we can be in the hospital
within a couple of hours. Once we go into a braking ellipse, we can reach
a hospital in less than an hour by snapper-boat."

"Let him go," MacFife said.

The doctor wasn't happy about it, but he had run out of arguments. "All
right, Commander--if you'll assume responsibility for getting him off the
asteroid and into a Terra or space platform hospital in time."

"I'll do that," MacFife assured him. "Now get your hyposprays and fill
him full of that stuff you use. The corporal, too."

"Sergeant," Rip corrected. His first action on getting back to the
asteroid would be to recommend Santos' promotion to Terra base. He
intended to recommend Kemp for corporal, too. He was sure the Planeteers
at Terra would make the promotions.

The two Federation cruisers were still holding course along with the
asteroid, the Connie cruiser between them.

Within an hour, Rip and Santos, both in false good health, thanks to
medical magic, were on their way back to the asteroid in a ball-bat boat.

The remaining time passed quickly. The sun receded. The Planeteers
corrected course. Rip sent in his recommendations for promotions and
looked over the last nuclear crater to see why the blast had started the
asteroid spinning.

The reason could only be guessed. The blast probably had opened a fault
in the crystal, allowing the explosion to escape partially in the wrong
direction.

Once the course was corrected, Rip calculated the position for the final
nuclear charge. When the asteroid reached the correct position relative
to Earth, the charge would not change its course but only slow its speed
somewhat. The asteroid would go around Earth in a series of ever
tightening ellipses, using Terra's gravity, plus rocket fuel, to slow
it down to orbital speed.

When it reached the proper position, tubes of rocket fuel would change
the course again, putting it into an orbit around Earth, close to the
space platform. It wasn't practical to take the thorium rock in for a
landing. They would lose control, and the asteroid would flame to Earth
like the greatest meteor ever to hit the planet.

Putting the asteroid into orbit around Earth was actually the most
delicate part of the whole trip, but Rip wasn't worried. He had the
facilities of Terra base within easy reach by communicator. He dictated
his data and let them do the mathematics on the giant electronic
computers.

He and his men rode the gray planet past the moon, so close they could
almost see the Planeteer lunar base, circled Terra in a series of
ellipses, and finally blasted the asteroid into its final orbit within
sight of the space platform.

Landing craft and snapper-boats swarmed to meet them, and within an hour
after their arrival the Planeteers were surrounded by spacemen, cadets
from the platform, and officers and men wearing Planeteer black.

A cadet approached Rip and looked at him with awe. "Sir, I don't know how
you ever did it!"

And Rip, his eyes on the great curve of Earth, answered casually,
"There's one thing every space chick has to learn if he's going to be a
Planeteer. There's always a way to do anything. To be a Planeteer, you
have to be able to figure out the way."

A new voice said, "Now, that's real wisdom!"

Rip turned quickly and looked through a helmet at the grinning face of
Maj. Joe Barris.

Barris spoke as though to himself, but Rip turned red as his hair. "Funny
how fast a man ages in space," the Planeteer major remarked. "Take
Foster. A few weeks ago he was just a cadet, a raw recruit who had never
met high vack. Now he's talking like the grandfather of all space. I
don't know how the Special Order Squadrons ever got along before he
became an officer."

Rip had been feeling a little too proud of himself.

"It's good to get back," Rip said.



CHAPTER TWENTY

On the Platform


There were two things Rip could see from his hospital bed on the space
platform. One was the great curve of Earth. He was anxious to get out
of the hospital and back to Terra.

The second thing was the asteroid. Spacemen were at work on it, slowly
cutting it to pieces. The pieces were small enough to be carried back to
Earth in supply rockets. It would be a long time before the asteroid was
completely cut up and transported to Terra base.

Sergeant Major Koa came into the hospital ward and sat on Rip's bed. The
plastifoam mattress compressed under his weight. "How are you feeling,
sir?"

"Pretty good," Rip replied. The worst of the radiation sickness was over,
and he was mending fast. Here and there were little bloodstains, just
below the surface of his skin, and he had no more hair than a plastic
ball. Otherwise he looked normal. The stains would go away, and his hair
would grow back in a few weeks.

Santos, now officially a sergeant, was in the same condition. The rest of
Rip's Planeteers had resumed duties on the space platform. He saw them
frequently, because they made a point of dropping in whenever they were
near the hospital area.

Koa looked out at the asteroid. "I sort of hate to see that rock cut up.
There isn't much about a chunk of thorium to get sentimental over, but
after fighting for it the way we did, it doesn't seem right to cut it
into blocks."

"I know how you feel," Rip admitted, "but, after all, that's what we
brought it back for."

He studied Koa's dark face. The sergeant major had something on his mind.
"Got vack worms chewing at you?" he asked. Vack worms were a spaceman's
equivalent of "the blues."

"Not exactly, sir. I happened to overhear the doctor talking today.
You're due for a leave in a week."

"That's good news!" Rip exclaimed. "You're not unhappy about it, are
you?"

Koa shrugged. "We were all hoping we'd be together on our next
assignment. The gang liked serving under you. But we're overdue for
shipment to somewhere, and if you take eight weeks' leave, we'll be gone
by the time you come back to the platform."

"I liked serving with all of you, too," Rip replied. "I watched the way
you all behaved when the space flap was getting tough, and it made me
proud to be a Planeteer."

Maj. Joe Barris came in. He was carrying an envelope in his hand.

"Hello, Rip. How are you, Koa? Am I interrupting a private talk?"

"No, Major," Koa replied. "We're just passing the time. Want me to
leave?"

"Stay here," Barris said. "This concerns you, too. I've been reassigned.
My eight years on the platform are up, and that's all an instructor gets.
Now I'm off for space on another job."

Rip knew that instructors were assigned for eight-year periods. And he
knew that the major's specialty was the Planeteer science of exploration,
a specialty which required him to be an expert in biology, zoology,
anthropology, navigation and astrogation, and land fighting--not to
mention a half dozen lesser things. Only ten Planeteers rated expert in
exploration, and all were captains or majors.

"Where are you going?" Rip asked. "Off to explore something?"

"That's it." Major Barris smiled. "Remember once I said that when they
gave me the job of cleaning up the goopies on Ganymede, I'd ask for you
as a platoon leader?"

Rip stared. "Don't tell me that's your assignment!"

"Almost. Tell me, would you recommend any more of your men for promotion?
I'll need a new sergeant and two more corporals."

Rip thought it over. "Koa can check me on this. I'd suggest making
Pederson a sergeant and Dowst and Dominico corporals. Kemp and Santos
already have promotions."

"That would be my choice, too," Koa agreed.

"Fine." Barris tapped the envelope. "I'll correct the orders in here
and recommend the promotions. We'll get sixteen new recruits from the
graduating class at Luna, and that will complete the platoon I'm supposed
to organize. Two full platoons are waiting, and the new platoon will give
me a full-strength squadron, except for new officers. How about Flip
Villa for a platoon commander, Rip?"

Rip knew the Mexican officer was among the best of his own graduating
class. "I have to admit prejudice," he warned. "Flip is a pal of mine.
But I don't think you could do better." His curiosity got the better of
him, and he asked "Can you tell me what this is all about?"

Joe Barris reached over and rubbed Rip's bald head. "By the time fur
grows back on that irradiated dome of yours, I'll be on my way with
Koa, Pederson, and the new recruits. Santos and the rest of your crew
will report to Terra base. Flip Villa will join them there. You'll be
on Earth leave for eight weeks, but it will take about that much time for
Flip and the men to assemble the supplies and equipment we'll need."

He pulled a sheaf of papers out of the envelope. "Koa, here are orders
for you and your men. They say you're to report to Special Order Squadron
Seven, on Ganymede. SOS Seven is a new squadron, the first one organized
exclusively for exploration duties, and I'm its commanding officer. Koa,
you'll be my senior noncommissioned officer. I want you and Pederson with
me, because you can organize the new recruits en route. They have a lot
more to learn from you than they got in their two years of training.
You'll make real Planeteers out of 'em."

He picked a paper from the sheaf and waived it at Rip. "This is for you,
Lieutenant Foster." He read, "Foster, R. I. P., Lieutenant, SOS. Serial
seven-nine-four-three. Authorized eight weeks' leave upon discharge from
hospital. Upon completion of leave, subject officer will report to Terra
base for transportation to SOS Seven on Ganymede."

Joe Barris handed Rip his new orders. "You'll be on the same ship with
Flip Villa and your men. Flip will be another of my platoon leaders.
I'll be waiting for you on Ganymede. The moons of Jupiter are going to be
our home for quite a while, Rip. Our first assignment is to explore
Callisto from pole to pole."

Rip didn't know what to say. To serve under Barris, to have his own men
in a regular squadron platoon, to have Flip Villa in the same outfit,
and to be assigned to exploration duty--dirtiest but most exciting of all
Planeteer jobs--was just too much. He couldn't say anything. He could
only grin.

Maj. Joe Barris looked at Rip's shiny head and chuckled. "From what I
hear of Callisto, we're in for a rough time. Your hair will probably
grow back just in time to turn gray!"
