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."

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 squadroom

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 either in high or

low space on special work. Chances are 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. If his estimate was correct, work at the Planeteer

base had 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 little Filipino 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."

Rip listened, interested. This was the talk of old space hands. They 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 simply "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, and not 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 squadroom 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 the items off.

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!

[Illustration: Great Cosmos! It Was An Atomic Bomb!]

Great Cosmos! It 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 10,000 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 detonators 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 spacefish, 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. Apparently there

was a time for spacemen and Planeteers to fight each other, and a time for

them to cooperate like friends. He hoped he’d catch on after a while.

"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.
