Rip Foster Rides the Gray Planet by Harold L. Goodwin (free reads .TXT) 📕

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.[pg 080] 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 men would tackle the problem. He didn't know the answer himself, because he had never driven a spike on an airless, almost gravityless world 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 the spur between his legs. 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 in. 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[pg 081] 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. Even the heaviest crates weighed almost nothing. They passed them from one to the other like 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[pg 082] 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 in 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 onto 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, the rest break out the rocket launcher and rocket racks and assemble the cutting torch. Koa will make assignments."

[pg 083]

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 this was his own personal planet. It would be a good bit of space humor to spring on the folks back on Terra.

[pg 084]

"Yep, I was boss of a whole world, once. 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'd better stop gathering spacedust 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 the 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, and wait until the gauges registered sufficient air and heat, then remove their space suits. When it was time to leave again, they would don suits, open the door and walk out,[pg 085] 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 showed the best design.

The rocket launcher was already set up near the boat. It was a simple affair, with four 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 was no gravity and no 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 took the data sheets from his case and examined them. Now came the work of finding the exact 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[pg 086] 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 he lost balance and floated above the surface like a captive balloon. Santos, who had been standing near by to help if requested, hooked a toe on a 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[pg 087] 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.

"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[pg 088] 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
