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 near-by 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 squadroom 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 over 100,000. Most of them

were only a mile or two in diameter. Others, much smaller, had never been

charted by anyone. One leading astronomer had estimated that as many as

50,000 asteroids filled the belt.

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

special knowledge."
