At that moment Joe really thought of Sally for the first time in a good two hours. She’d been anxious that living in the Platform should be as normal and Earth-like as possible. The total absence of weight would be bad enough. She believed it needed to be countered, as a psychological factor in staying sane, by the effect of normal-seeming chairs and normal-tasting food, and not too exotic systems for eating.
Joe asked Brent about it.
“Oh, yes,” said Brent mildly. “It’s likely we’d all have gone off the deep end if there weren’t some familiar things about. To have to drink from a cup that one squeezes is tolerable. But we’d have felt hysterical at times if we had to drink everything from the equivalent of baby bottles.”
“Sally Holt,” said Joe, “is a friend of mine. She helped design this stuff.”
“That girl has every ounce of brains that any woman can be trusted with!” Brent said warmly. “She thought of things that would never have occurred to me! As a psychologist, I could see how good her ideas were when she brought them up, but as a male I’d never have dreamed of them.” Then he grinned. “She fell down on just one point. So did everybody else. Nobody happened to think of a garbage-disposal system for the Platform.”
It came into Joe’s mind that garbage-disposal was hardly a subject one would expect to be discussing in interplanetary space. But the Platform wasn’t the same thing as a spaceship. A ship could jettison refuse and leave it behind, or store it during a voyage and dump it at either end. But the Space Platform would never land. It could roll on forever. And if it heaved out its refuse from airlocks—why—the stuff would still have the Platform’s orbital speed and would follow it tirelessly around the Earth until the end of time.
“We dry and store it now,” said Brent. “If we were going to live, we’d figure out some way to turn it to fertilizer for the hydroponic gardens. It’s hardly worth while as things are. Even then, though, the problem of tin cans could be hopeless.”
The Chief wiped his mouth deliberately. He had helped load four guided-missile launching tubes, and he had been brought up to date on the state of things in the Platform. He growled in a preliminary fashion and said, “Joe.”
Joe looked at him.
“We brought up six two-ton guided missiles,” said the Chief dourly. “We’ll have warning of other bombs coming up. We can send these missiles out to intercept ’em. Six of ’em. They can get close enough to set off their proximity fuses, anyhow. But what are we going to do, Joe, if somebody flings seven bombs at us? We can manage six—maybe. But what’ll we do with the one that’s left over?”
“Have you any ideas?” asked Joe.
The Chief shook his head. Brent said mildly. “We’ve worked on that here in the Platform, I assure you. And as Sanford puts it quite soundly, about the only thing we can really do is throw our empty tin cans at them.”
Joe nodded. Then he tensed. Brent had meant it as a rather mirthless joke. But Joe was astonished at what his own brain made of it. He thought it over. Then he said, “Why not? It ought to be a very good trick.”
Brent stared at him incredulously. Haney looked solemnly at him. The Chief regarded Joe thoughtfully out of the corner of his eye. Then Mike shouted gleefully. The Chief blinked, and a moment later grunted wrathful unintelligible syllables of Mohawk, and then tried to pound Joe on the back and because of his want of weight went head over heels into the air between the six walls of the kitchen.
Haney said disgustedly, “Joe, there are times when a guy wants to murder you! Why didn’t I think of that?”
But Brent was looking at the four of them with a lively, helpless curiosity. “Will you guys let me in on this?”
They told him. Joe began to explain it carefully, but the Chief broke in with a barked and impatient description, and then Mike interrupted to snap a correction. But by that time Brent’s expression had changed with astonishing suddenness.
“I see! I see!” he said excitedly. “All right! Have you got space suits in your ship? We have them. So we’ll go out and pelt the stars with garbage. I think we’d better get at it right now, too. In under two hours we’ll be a fine target for more bombs, and it would be good to start ahead of time.”
Mike made a gesture and went floating out of the kitchen, air-swimming to go get space suits from the ship. The grin on his small face threatened to cut his throat. Joe asked, “Sanford’s in command. How’ll he like this idea?”
Brent hesitated. “I’m afraid,” he said regretfully, “he won’t like it. If you solve a problem he gave up, it will tear his present adjustment to bits. He’s gone psychotic. I think, though, that he’ll allow it to be tried while he swears at us for fools. He’s most likely to react that way if you suggest it.”
“Then,” agreed Joe, “I suggest it. Chief—”
The Chief raised a large brown hand.
“I got the program, Joe,” he said. “We’ll all get set.”
And Joe went floating unhappily through passage-tubes to the control room. He heard Sanford’s voice, sardonic and mocking, as he reached the communications room door.
“What do you expect?” Sanford was saying derisively. “We’re clay pigeons. We’re a perfect target. We’ve just so much ammunition now. You say you may send us more in three weeks instead of a month. I admire your persistence, but it’s really no use! This is all a very stupid business.…”
He felt Joe’s presence. He turned, and then sharply struck the communicator switch with the heel of his hand. The image on the television screen died. The voice cut off. He said blandly: “Well?”
“I want,” said Joe, “to take a garbage-disposal party out on the outside of the Platform. I came to ask for authority.”
Sanford looked at him in mocking surprise.
“To be sure it seems as intelligent as anything else the human race has ever done,” he observed. “But why does it appeal to you as something you want to do?”
“I think,” Joe told him, “that we can make a defense against bombs from Earth with our empty tin cans.”
Sanford raised his eyebrows.
“If you happen to have a four-leaf clover with you,” he said in fine irony, “I’m told they’re good, too.”
His eyes were bright and scornful. His manner was feverishly derisive. Joe would have done well to let it go at that. But he was nettled.
“We set off the last bombs,” he said doggedly, “by shooting our landing rockets at them. They didn’t collide with the bombs. They simply touched off the bombs’ proximity fuses. If we surround the Platform with a cluster of tin cans and such things, they may do as well. Things we throw away won’t drop to Earth. Ultimately, they’ll actually circle us, like satellites themselves. But if we can get enough of them between us and Earth, any bombs that come up will have their proximity fuses detonated by the floating trash we throw out.”
Sanford laughed.
“We might ask for aluminum-foil ribbon to come up in the next supply ship,” said Joe. “We could have masses of that, or maybe metallic dust floating around us.”
“I much prefer used tin cans,” said Sanford humorously. “I’ll take the watch here and let everybody go out with you. By all means we must defend ourselves. Forward with the garbage! Go ahead!”
His eyes were almost hysterically scornful as he waited for Joe to leave. Joe did not like it at all, but there was nothing to do but get out.
He found the Chief with a net bag filled with emptied tin cans. Haney had another. There were two more, carried by members of the Platform’s four-man crew. They were donning their space suits when Joe came upon them. Mike was grotesque in the cut-down outfit built for him. Actually, the only difference was in the size of the fabric suit and the length of the arms and legs. He could carry a talkie outfit with its batteries, and the oxygen tank for breathing as well as anybody, since out here weight did not count at all. There were plastic ropes, resistant to extremes of temperature.
Joe got into his own space suit. It was no such self
-contained space craft in itself as the fantastic story tellers dreamed of. It was not much more than an altitude suit, aluminized to withstand the blazing heat of sunshine in emptiness, and with extravagantly insulated soles to the magnetic boots. In theory, there simply is no temperature in space. In practice, a metal hull heats up in sunshine to very much more than any record-hot-day temperature on Earth. In shadow, too, a metal hull will drop very close to minus 250 degrees Centigrade, which is something like 400 degrees Fahrenheit below zero. But mainly the space boots were insulated against the almost dull-red-heat temperatures of long-continued sunshine.
A crewman named Corey moved into an airlock with one of the bags of empty tin cans. Brent watched in a routine fashion through a glass in the lock-door. The pumps began to exhaust the air from the airlock. Corey’s space suit inflated visibly. Presently the pump stopped. Corey opened the outer door. He went out, paying plastic rope behind him. An instant later he reappeared and removed the rope. He’d made his line fast outside. He closed the outer lock-door. Air surged into the lock and Haney crowded in. Again the pumping. Then Haney went out, and was anchored to the Platform not only by his magnetic boots but by a rope fastened to a hand-hold. Brent went out. Mike. Joe came next.
They stood on the hull of the Space Platform, waiting in the incredible harsh sunshine of emptiness. The bright steel plates of the hull swelled and curved away on every hand. There were myriads of stars and the vast round bulk of Earth seemed farther away to a man in a space suit than to a man looking out a port. Where shadows cut across the Platform’s irregular surface, there was utter blackness. Also there was horrible frigidity. Elsewhere it was blindingly bright. The men were specks of humanity standing on a shining metal hull, and all about them there was the desolation of nothingness.
But Joe felt strangely proud. The seventh man came out of the lock-door. They tied their plastic ropes together and spread out in a long line which went almost around the Platform. The man next to the lock was anchored to a steel hand-hold. The third man of the line also anchored himself. The fifth. The seventh. They were a straggling line of figures with impossibly elongated shadows, held together by ropes. They were peculiarly like a party of weirdly costumed mountaineers on a glacier of gleaming silver.
But no mountain climbers ever had a background of ten thousand million stars, peering up from below them as well as from overhead. Nor did any ever have a mottled greenish planet rolling by 4,000 miles beneath them, nor a blazing sun glaring down at them from a sky such as this.
In particular, perhaps, no other explorers ever set out upon an expedition whose purpose was to throw tin cans and dried refuse at all the shining cosmos.
They set to work. The space suits were inevitably clumsy. It was not easy to throw hard with only magnetism to hold one to his feet. It was actually more practical to throw straight up with an underhand gesture. But even that would send the tin cans an enormous distance, in time. There was no air to slow them.
The tin cans twinkled as they left the Platform’s steel expanse. They moved away at a speed of possibly 20 to 30 miles an hour. They floated off in all possible directions. They would never reach Earth, of course. They shared the Platform’s orbital speed, and they would circle the Earth with it forever. But when they were thrown away, their orbits were displaced a little. Each can thrown downward just now, for example, would always be between the Platform and the Earth on this side of its orbit. But on the other side of Earth it would be above the Platform. The Platform, in fact, became the center of a swarm, a cluster, a cloud of infinitesimal objects which would always accompany it and always be in motion with regard to it. Together, they should make up a screen no proximity fuse bomb could pierce without exploding.
Joe heard clankings, transmitted to his body through his feet.
“What’s that?” he demanded sharply. “It sounds like the airlock!”
Voices mingled in his ears. The other walkie-talkies allowed everybody to speak at once. Most of them did. Then Joe heard someone laugh. It was Sanford’s voice.
Sandford’s aluminized, space-suited figure came clanking around the curve of the small metal world. The antenna of his walkie-talkie glittered above his head. He seemed to swagger against the background of many-colored stars.
Brent spoke quickly, before anyone else could question Sanford. His tone was mild and matter of fact, but Joe somehow knew the tension behind it.
“Hello, Sanford. You came out? Was it wise? Shouldn’t there be someone inside the Platform?”
Sanford laughed again. “It was very wise. We’re going to be killed, as you fellows know perfectly well. It’s futile to try to avoid it. So very sensibly I’ve decided to spare myself the nuisance of waiting to be killed. I came out.”
There was silence in the ear-phones of Joe’s space suit radio. He heard his own heart beating loudly and steadily in the absolute stillness.
“Incidentally,” said Sanford with almost hysterical amusement, “I fixed it so that none of us can get back in. It would be useless, anyhow. Everything’s futility. So I’ve put an end to our troubles for good. I’ve locked us all out.”
He laughed yet again. And Joe knew that in Sanford’s madness it was perfectly possible for him to have done exactly what he said.
There were eight human beings on the Platform. All were now outside it, on its outer skin. They wore space suits with from half an hour to an hour’s oxygen supply. They had no tools with which to break back into the satellite. And no help could possibly reach them in less than three weeks.
If they couldn’t get back inside the Platform, Sanford, laughing proudly, had killed them all.

There was a babbling of angry, strained, tense voices in Joe’s headphones. Then the Chief roared for silence. It fell, save for Sanford’s quiet, hysterical chuckling. Joe found himself rather absurdly thinking that Sanford was not actually insane, except as any man may be who believes only in his own cleverness. Sooner or later it is bound to fail him. On Earth, Sanford’s pride in his own intellect had been useful. He had been brilliant because he accepted every problem and every difficulty as a challenge. But with the Platform’s situation seemingly hopeless, he’d been starkly unable to face the fact that he wasn’t clever or brilliant or intelligent enough. If Joe’s solution to the proximity fuse bombs had been offered before his emotional collapse, he could have accepted it grandly, and in so doing have made it his own. But it was too late for that now. He’d given up and worked up a frantic scorn for the universe he could not cope with. For Joe’s trick to work would have made him inferior even to Joe in his own view. And he couldn’t have that! Even to die, with the prospect that others would survive him, was an intolerable prospect. He had to be smarter than anybody else.
So he chuckled. The Chief roared wrathfully into his transmitter: “Quiet! This crazy fool’s tried to commit suicide for all of us! How about it? Why can’t we get back in? How many locks—”
Joe found himself thinking hard. He could be angry later. Now there wasn’t time. Thirty or forty minutes of breathing. No tools. A steel hull. The airlocks were naturally arranged for the greatest possible safety under normal conditions. In every airlock it had naturally been arranged so that the door to space and the door to the interior could not be open at the same time. That was to save lives. To save air, it would naturally be arranged that the door to space couldn’t be opened until the lock was pumped empty.
That in itself could be an answer. Joe said sharply, “Hold it, Chief! Somebody watch Sanford! All we’ve got to do is find which lock he came out of. He couldn’t get out until he pumped it empty—and that unlocks the outer door!”
But Sanford laughed once more. He sounded like someone in the highest of high good humor.
“Heroic again, eh? But I took a compressed air bottle in the lock with me. When the outer door was open, I opened the stopcock and shut the door. The air bottle filled the lock behind me. Naturally I’d fasten the door after I came out! One must be int
elligent!”
Joe heard Brent muttering, “Yes, he’d do that!”
“Somebody check it!” snapped Joe. “Make sure! It might amuse him to watch us die while he knew we could get back in if we were as smart as he is.”
There were clankings on the hull. Men moved, unfastening the lines which held them to the hull to get freedom of movement, but not breaking the links which bound them to each other. Joe saw Haney go grimly back to the task of throwing away the stuff that they had brought out for the purpose. Then Mike’s voice, brittle and cagey: “Haney! Quit it!”
Sanford’s voice again, horribly amused. “By all means! Don’t throw away our garbage! We may need it!”
A voice snapped, “This lock’s fastened.” Another voice: “And this.…” Other voices, with increasing desperation, verified that every airlock was implacably sealed fast by the presence of air pressure inside the lock itself.
Time was passing. Joe had never noticed, before, the minute noises of the air pressure apparatus strapped to his back. His exhaled breath went to a tiny pump that forced it through a hygroscopic filter which at once extracted excess moisture and removed carbon dioxide. The same pump carefully measured a volume of oxygen equal to the removed CO2 and added it to the air it released. The pump made very small sounds indeed, and the valves were almost noiseless, but Joe could hear their clickings.
Something burned him. He had been standing perfectly still while trying to concentrate on a way out. Sunshine had shone uninterruptedly on one side of his space suit for as long as five minutes. Despite the insulation inside, that was too long. He turned quickly to expose another part of himself to the sunlight. He knew abstractedly that the metal underfoot would sear bare flesh that touched it. A few yards away, in the shadow, the metal of the hull would be cold enough to freeze hydrogen. But here it was fiercely hot. It would melt solder. It might—
