Space Tug, Murray Leinster [feel good books to read TXT] 📗

They saw the metal floor, and the bulging plastic sidewalls, restrained by nets. They saw the inner lock-door. It seemed that men should be visible to welcome them. There were none.

The airlock swallowed them. They touched against something solid. There were more clankings. They seemed to crunch against the metal floor—magnetic flooring-grapples. Then, in solid contact with the substance of the Platform, they heard the sounds of the great outer doors swinging shut. They were within the artificial satellite of Earth. It was bright in the lock, and Joe stared out the cabin ports at the quilted sides. There was a hissing of air, and he saw a swirling mist, and then the bulges of the sidewall sagged. The air pressure gauge was spinning up toward normal sea-level air pressure.

Joe threw the ready lever of the steering rockets to Off. "We're landed."

There was silence. Joe looked about him. The other three looked queer. It would have seemed natural for them to rejoice on arriving at their destination. But somehow they didn't feel that they had.

Joe said wrily, "It seems that we ought to weigh something, now we've got here. So we feel queer that we don't. Shoes, Mike?"

Mike peeled off the magnetic-soled slippers from their place on the cabin wall. He handed them out and opened the door. A biting chill came in it. Joe slipped on the shoe-soles with their elastic bands to hold them. He stepped out the door.

He didn't land. He floated until he reached the sidewall. Then he pulled himself down by the netting. Once he touched the floor, his shoes seemed to be sticky. The net and the plastic sidewalls were, of course, the method by which a really large airlock was made practical. When this ship was about to take off again, pumps would not labor for hours to pump the air out. The sidewalls would inflate and closely[Pg 38] enclose the ship's hull, and so force the air in the lock back into the ship. Then the pumps would work on the air behind the inflated walls—with nets to help them draw the wall-stuff back to let the ship go free. The lock could be used with only fifteen minutes for pumping instead of four hours.

The door in the back of the lock clanked open. Joe tried to walk toward it. He discovered his astounding clumsiness. To walk in magnetic-soled shoes in weightlessness requires a knack. When Joe lifted one foot and tried to swing the other forward, his body tried to pivot. When he lifted his right foot, he had to turn his left slightly inward. His arms tried to float absurdly upward. When he was in motion and essayed to pause, his whole body tended to continue forward with a sedate toppling motion that brought him down flat on his face. He had to put one foot forward to check himself. He seemed to have no sense of balance. When he stood still—his stomach queasy because of weightlessness—he found himself tilting undignifiedly forward or back—or, with equal unpredictability, sidewise. He would have to learn an entirely new method of walking.

A man came in the lock, and Joe knew who it was. Sanford, the senior scientist of the Platform's crew. Joe had seen him often enough on the television screen in the Communications Room at the Shed. Now Sanford looked nerve-racked, but his eyes were bright and his expression sardonic.

"My compliments," he said, his voice tight with irony, "for a splendidly futile job well done! You've got your cargo invoice?"

Joe nodded. Sanford held out his hand. Joe fumbled in his pocket and brought out the yellow sheet.

"I'd like to introduce my crew," said Joe. "This is Haney, and Chief Bender, and Mike Scandia." He waved his hand, and his whole body wobbled unexpectedly.

"We'll know each other!" said Sanford sardonically. "Our first job is more futility—to get the guided missiles you've brought us into the launching tubes. A lot of good they'll do!"

A huge plate in the roof of the lock—but it was not up or down or in any particular direction—withdrew itself. A[Pg 39] man floated through the opening and landed on the ship's hull; another man followed him.

"Chief," said Joe, "and Haney. Will you open the cargo doors?"

The two swaying figures moved to obey, though with erratic clumsiness. Sanford called sharply: "Don't touch the hull without gloves! If it isn't nearly red-hot from the sunlight, it'll be below zero from shadow!"

Joe realized, then, the temperature effects the skin on his face noticed. A part of the spaceship's hull gave off heat like that of a panel heating installation. Another part imparted a chill.

Sanford said unpleasantly, "You want to report your heroism, eh? Come along!"

He clanked to the doorway by which he had entered. Joe followed, and Mike after him.

They went out of the lock. Sanford suddenly peeled off his metal-soled slippers, put them in his pocket, and dived casually into a four-foot metal tube. He drifted smoothly away along the lighted bore, not touching the sidewalls. He moved in the manner of a dream, when one floats with infinite ease and precision in any direction one chooses.

Joe and Mike did not share his talent. Joe launched himself after Sanford, and for perhaps 20 or 30 feet the lighted aluminum sidewall of the tube sped past him. Then his shoulder rubbed, and he found himself skidding to an undignified stop, choking the bore. Mike thudded into him.

"I haven't got the hang of this yet," said Joe apologetically.

He untangled himself and went on. Mike followed him, his expression that of pure bliss. He was a tiny man, was Mike, but he had the longings and the ambitions of half a dozen ordinary-sized men in his small body. And he had known frustration. He could prove by mathematics that space exploration could be carried on by midgets at a fraction of the cost and risk of the same job done by normal-sized men. He was, of course, quite right. The cabins and air and food supplies for a spaceship's crew of midgets would cost and weigh a fraction of similar equipment for six-footers. But[Pg 40] people simply weren't interested in sending midgets out into space.

But Mike had gotten here. He was in the Space Platform. There were full-sized men who would joyfully have changed places with him, forty-one inch height and all. So Mike was blissful.

The tube ended and Joe bounced off the wall that faced its end. Sanford was waiting. He grinned with more than a hint of spite.

"Here's our communications room," he said. "Now you can talk down to Earth. It'll be relayed, now, but in half an hour you can reach the Shed direct."

He floated inside. Joe followed cautiously. There was another crew member on duty there. He sat before a group of radar screens, with thigh grips across his legs to hold him in his chair. He turned his head and nodded cheerfully enough.

"Here!" snapped Sanford.

Joe clambered awkwardly to the seat the senior crew member pointed out. He made his way to it by handholds on the walls. He fumbled into the chair and threw over the curved thigh grips that would hold him in place.

Suddenly he was oriented. He had seen this room before—before the Platform was launched. True, the man at the radar screens was upside-down with reference to himself, and Sanford had hooked a knee negligently around the arm of a firmly anchored chair with his body at right angles to Joe's own, but at least Joe knew where he was and what he was to do.

"Go ahead and report," said Sanford sardonically. "You might tell them that you heroically destroyed the rockets that attacked us, and that your crew behaved splendidly, and that you have landed in the Space Platform and the situation is well in hand. It isn't, but it will make nice headlines."

Joe said evenly, "Our arrival's been reported?"

"No," said Sanford, grinning. "Obviously the radar down on Earth—shipboard ones on this hemisphere, of course—have[Pg 41] reported that the Platform still exists. But we haven't communicated since the bombs went off. They probably think we had so many punctures that we lost all our air and are all wiped out. They'll be glad to hear from you that we aren't."

Joe threw a switch, frowning. This wasn't right. Sanford was the senior scientist on board and hence in command, because he was best-qualified to direct the scientific observations the Platform was making. But there was something specifically wrong.

The communicator hummed. A faint voice sounded. It swelled to loudness. "Calling Space Platform! Calling Space Platform! CALLING SPACE PLATFORM!" Joe turned down the volume. He said into the microphone:

"Space Platform calling Earth. Joe Kenmore reporting. We have made contact with the Platform and completed our landing. Our cargo is now being unloaded. Our landing rockets had to be expended against presumably hostile bombs, and we are now unable to return to Earth. The ship and the Platform, however, are unharmed. I am now waiting for orders. Report ends."

He turned away from the microphone. Sanford said sharply, "Go on! Tell them what a hero you are!"

"I'm going to help unload my ship," Joe said shortly. "You report what you please."

"Get back at that transmitter!" shouted Sanford furiously. "Tell 'em you're a hero! Tell 'em you're wonderful! I'll tell 'em how useless it is!"

Joe saw the other man in the room, the man at the radar screens, shake his head. He got up and fumbled his way along the wall to the door. Sanford shouted after him angrily.

Joe went out, found the four-foot tunnel, and floated not down but along it back to the unloading lock. Wordlessly, he set to work to get the cargo out of the cargo hold of the spaceship.

Handling objects in weightlessness which on Earth would be heavy was an art in itself. Two men could move tons. It needed only one man to start a massive crate in motion.[Pg 42] However, one had either to lift or push an object in the exact line it was to follow. To thrust hard for a short time produced exactly the same effect as to push gently for a longer period. Anything floated tranquilly in the line along which it was moved. The man who had to stop it, though, needed to use exactly as much energy as the man who sent it floating. He needed to check the floating thing in exactly the same line. If one tried to stop a massive shipment from one side, he would topple into it and he and the crate together would go floundering helplessly over each other.

The Chief had gone off to help maneuver two-ton guided missiles into launching tubes. One crew member remained with Haney, unloading things that would have had to be handled with cranes on Earth. Joe found himself needed most in the storage chamber. A crate floated from the ship to the crewman. Standing head downward, he stopped its original movement, braced himself, and sent it floating to Joe. He braced himself, stopped its flight, and very slowly—to move fast with anything heavy in his hands would pull his feet from the floor—set it on a stack of similar objects which would presently be fastened in place.

Everything had to be done in slow motion, or one would lose his footing. Joe worked painstakingly. He gradually began to understand the process. But the muscles of his stomach ached because of their continuous, instinctive cramp due to the sensation of unending fall.

Mike floated through the hatchway from the lock. He twisted about as he floated, and his magnetized soles clanked to a deft contact with the wall. He said calmly: "That guy Sanford has cracked up. He's potty. If this were jail he'd be stir-crazy. He's yelling into the communicator now that we'll all be dead in a matter of days, and the rocket missiles we brought up won't help. He's nasty about it, too!"

Haney called from the cargo space of the ship in the lock: "All empty here! We're unloaded."

There were sounds as he closed the cargo doors. Haney, followed by the Chief, came into view, floating as Mike had done. But he didn't land as skillfully. He touched the wall on[Pg 43] his hands and knees and bounced away and tried helplessly to swim to a hand-hold. It would have been funny except that Joe was in no mood for humor.

Mike whipped off his belt and flipped the end of it to Haney. He caught it and was drawn gently to the wall. Haney's shoes clicked to a hold. The Chief landed more expertly.

"We need wings here," he said ruefully. "You reported, Joe?"

Joe nodded. He turned to Brent, the crew member who'd been unloading. He knew him too, from their two-way video conversations.

"Sanford does act oddly," he said uncomfortably. "When he met me in the lock he said our coming was useless. He talked about the futility of everything while I reported. He sounds like he sneers at every possible action as useless."

"Most likely it is," Brent
