“There was a man out there,” he said curtly. “I think it is your friend Braun. I’ll get you to look and identify.”
Joe had suspected as much. He waited.
“He’d opened a container of cobalt powder. It was in a beryllium case. There was half a pound of it. It killed him.”
“Radioactive cobalt,” said Joe.
“Definitely,” said the Major grimly. “Half a pound of it gives off the radiation of an eighth of a ton of pure radium. One can guess that he had been instructed to get up as high as he could in the Shed and dump the powder into the air. It would diffuse—scatter as it sifted down. It would have contaminated the whole Shed past all use for years—let alone killing everybody in it.”
Joe swallowed.
“He was burned, then.”
“He had the equivalent of two hundred and fifty pounds of radium within inches of his body,” the Major said unbendingly, “and naturally it was not healthy. For that matter, the container itself was not adequate protection for him. Once he’d carried it in his pocket for a very few minutes, he was a dead man, even though he was not conscious of the fact.”
Joe knew what was wanted of him.
“You want me to look at him,” he said.
The Major nodded.
“Yes. Afterward, get a radiation check on yourself. It is hardly likely that he was—ah—carrying the stuff with him last night, in Bootstrap. But if he was—ah—you may need some precautionary treatment—you and the men who were with you.”
Joe realized what that meant. Braun had been given a relatively small container of the deadliest available radioactive material on Earth. Milligrams of it, shipped from Oak Ridge for scientific use, were encased in thick lead chests. He’d carried two hundred and fifty grams in a container he could put in his pocket. He was not only dead as he walked, under such circumstances. He was also death to those who walked near him.
“Somebody else may have been burned in any case,” said the Major detachedly. “I am going to issue a radioactivity alarm and check every man in Bootstrap for burns. It is—ah—very likely that the man who delivered it to this man is burned, too. But you will not mention this, of course.”
He waved his hand in dismissal. Joe turned to go. The Major added grimly: “By the way, there is no doubt about the booby-trapping of planes. We’ve found eight, so far, ready to be crashed when a string was pulled while they were serviced. But the men who did the booby-trapping have vanished. They disappeared suddenly during last night. They were warned! Have you talked to anybody?”
“No sir,” said Joe.
“I would like to know,” said the Major coldly, “how they knew we’d found out their trick!”
Joe went out. He felt very cold at the pit of his stomach. He was to identify Braun. Then he was to get a radiation check on himself. In that order of events. He was to identify Braun first, because if Braun had carried a half-pound of radioactive cobalt on him in Sid’s Steak Joint the night before, Joe was going to die. And so were Haney and the Chief and Mike, and anybody else who’d passed near him. So Joe was to do the identification before he was disturbed by the information that he was dead.
He made the identification. Braun was very decently laid out in a lead-lined box, with a lead-glass window over his face. There was no sign of any injury on him except from his fight with Haney. The radiation burns were deep, but they’d left no marks of their own. He’d died before outer symptoms could occur.
Joe signed the identification certificate. He went to be checked for his own chances of life. It was a peculiar sensation. The most peculiar was that he wasn’t afraid. He was neither confident that he was not burned inside, nor sure that he was. He simply was not afraid. Nobody really ever believes that he is going to die—in the sense of ceasing to exist. The most arrant coward, stood before a wall to be shot, or strapped in an electric chair, finds that astoundingly he does not believe that what happens to his body is going to kill him, the individual. That is why a great many people die with reasonable dignity. They know it is not worth making too much of a fuss over.
But when the Geiger counters had gone over him from head to foot, and his body temperature was normal, and his reflexes sound—when he was assured that he had not been exposed to dangerous radiation—Joe felt distinctly weak in the knees. And that was natural, too.
He went trudging back to the wrecked gyros. His friends were gone, leaving a scrawled memo for him. They had gone to pick out the machine tools for the work at hand.
He continued to check over the wreckage, thinking with a detached compassion of that poor devil Braun who was the victim of men who hated the idea of the Space Platform and what it would mean to humanity. Men of that kind thought of themselves as superior to humanity, and of human beings as creatures to be enslaved. So they arranged for planes to crash and burn and for men to be murdered, and they practiced blackmail—or rewarded those who practiced it for them. They wanted to prevent the Platform from existing because it would keep them from trying to pull the world down in ruins so they could rule over the wreckage.
Joe—who had so recently thought it likely that he would die—considered these actions with an icy dislike that was much deeper than anger. It was backed by everything he believed in, everything he had ever wanted, and everything he hoped for. And anger could cool off, but the way he felt about people who would destroy others for their own purposes could not cool off. It was part of him. He thought about it as he worked, with all the noises of the Shed singing in his ears.
A voice said: “Joe.”
He started and turned. Sally stood behind him, looking at him very gravely. She tried to smile.
“Dad told me,” she said, “about the check-up that says you’re all right. May I congratulate you on your being with us for a while?—on the cobalt’s not getting near you?—or the rest of us?”
Joe did not know exactly what to say.
“I’m going inside the Platform,” she told him. “Would you like to come along?”
He wiped his hands on a piece of waste.
“Naturally! My gang is off picking out tools. I can’t do much until they come back.”
He fell into step beside her. They walked toward the Platform. And it was still magic, no matter how often Joe looked at it. It was huge beyond belief, though it was surely not heavy in proportion to its size. Its bright plating shone through the gossamer scaffolding all about it. There was always a faint bluish mist in the air, and there were the marsh-fire lights of welding torches playing here and there. The sounds of the Shed were a steady small tumult in Joe’s ears. He was getting accustomed to them, though.
“How is it you can go around so freely?” he asked abruptly. “I have to be checked and rechecked.”
“You’ll get a full clearance,” she told him. “It has to go through channels. Me—I have influence. I always come in through security, and I have the door guards trained. And I do have business in the Platform.”
He turned his head to look at her.
“Interior decoration,” she explained. “And don’t laugh! It isn’t prettifying. It’s psychology. The Platform was designed by engineers and physicists and people with slide rules. They made a beautiful environment for machinery. But there will be men living in it, and they aren’t machines.”
“I don’t see—”
“They designed the hydroponic garden,” said Sally with a certain scorn.“They calculated very neatly that eleven square feet of leaf surface of a pumpkin plant will purify all the air a resting man uses, and so much more will purify the air a man uses when he’s working hard. So they designed the gardens for the most efficient production of the greatest possible leaf surface—of pumpkin plants! They figured food would be brought up by the tender rockets! But can you imagine the men in the Platform, floating among the stars, living on dehydrated food and stuffing themselves hungrily with pumpkins because that is the only fresh food they have?”
Joe saw the irony.
“They�
��re thinking of mechanical efficiency,” said Sally indignantly. “I don’t know anything about machinery, but I’ve wasted an awful lot of time at school and otherwise if I don’t know something about human beings! I argued, and the garden now isn’t as mechanically efficient, but it’ll be a nice place for a man to go into. He won’t smell pumpkin plants all the time, either. I’ve even gotten them to include some flowers!”
They were very near the Platform. And it was very near to completion. Joe looked at it hungrily, and he felt a great sense of urgency. He tried to strip away the scaffolding in his mind and see it floating proudly free in emptiness, with white-hot sunshine glinting from it, and only a background of unwinking stars.
Sally’s voice went on: “And I’ve really put up an argument about the living quarters. They had every interior wall painted aluminum! I argued that in space or out of it, where people have to live, it’s housekeeping. This is going to be their home. And they ought to feel human in it!”
They passed into one of the openings in the maze of uprights. All about them there were trucks, and puffing engines, and hoists. Joe dragged Sally aside as a monstrous truck-and-trailer came from where it had delivered some gigantic item of interior use. It rumbled past them, and she led the way to a flight of temporary wooden stairs with two security guards at the bottom. Sally talked severely to them, and they grinned and waved for Joe to go ahead. He went up the steps—which would be pulled down before the Platform’s launching—and went actually inside the Space Platform for the first time.
It was a moment of extreme vividness for him. Within the past hour he’d come to think detachedly of the possibility of death for himself, and then had learned that he would live for a while yet. He knew that Sally had been scared on his account, and that her matter-of-fact manner was partly assumed. She was at least as much wrought up as he was.
And this was the first time he was going into what would be the first space ship ever to leave the Earth on a non-return journey.

Nobody could have gone through the changes of emotion Joe had experienced that morning and remained quite matter-of-fact. Seeing a dead man who had more or less deliberately killed himself so that he wouldn’t have to kill Joe—for one—had its effect. Knowing that it was certainly possible the man hadn’t killed himself in time had another. Being checked over for radiation burns which would mean that he’d die quite comfortably within three or four days, and then learning that no burns existed, was something of an ordeal. And Sally—of course her feelings shouldn’t have been as vivid as his own, but the fact that she’d been scared for him held some significance. When, on top of all the rest, he went into the Space Platform for the first time, Joe was definitely keyed up.
But he talked technology. He examined the inner skin and its lining before going beyond the temporary entrance. The plating of the Platform was actually double. The outer layer was a meteor-bumper against which particles of cosmic dust would strike and explode without damage to the inner skin. They could even penetrate it without causing a leak of air. Inside the inner skin there was a layer of glass wool for heat insulation. Inside the glass wool was a layer of material serving exactly the function of the coating of a bulletproof gasoline tank. No meteor under a quarter-inch size could hope to make a puncture, even at the forty-five-mile-per-second speed that is the theoretical maximum for meteors. And if one did, the selfsealing stuff would stop the leak immediately. Joe could explain the protection of the metal skins. He did.
“When a missile travels fast enough,” he said absorbedly, “it stops acquiring extra puncturing ability. Over a mile a second, impact can’t be transmitted from front to rear. The back end of the thing that hits has arrived at the hit place before the shock of arrival can travel back to it. It’s like a train in a collision which doesn’t stop all at once. A meteor hitting the Platform will telescope on itself like the cars of a railroad train that hits another at full speed.”
Sally listened enigmatically.
“So,” said Joe, “the punching effect isn’t there. A meteor hitting the Platform won’t punch. It’ll explode. Part of it will turn to vapor—metallic vapor if it’s metal, and rocky vapor if it’s stone. It’ll blow a crater in the metal plate. It’ll blow away as much weight of the skin as it weighs itself. Mass for mass. So that weight for weight, pea soup would be just as effective armor against meteors as hardened steel.”
Sally said: “Dear me! You must read the newspapers!”
“The odds figure out, the odds are even that the Platform won’t get an actual meteor puncture in the first twenty thousand years it’s floating round the Earth.”
“Twenty thousand two seventy, Joe,” said Sally. She was trying to tease him, but her face showed a little of the strain. “I read the magazine articles too. In fact I sometimes show the tame article writers around, when they’re cleared to see the Platform.”
Joe winced a little. Then he grinned wryly.
“That cuts me down to size, eh?”
She smiled at him. But they both felt queer. They went on into the interior of the huge space ship.
“Lots of space,” said Joe. “This could’ve been smaller.”
“It’ll be nine-tenths empty when it goes up,” said Sally. “But you know about that, don’t you?”
Joe did know. The reasons for the streamlining of rockets to be fired from the ground didn’t apply to the Platform. Not with the same urgency, anyhow. Rockets had to burn their fuel fast to get up out of the dense air near the ground. They had to be streamlined to pierce the thick, resisting part of the atmosphere. The Platform didn’t. It wouldn’t climb by itself. It would be carried necessarily at slow speed up to the point where jet motors were most efficient, and then it would be carried higher until they ceased to be efficient. Only when it was up where air resistance was a very small fraction of ground-level drag would its own rockets fire. It wouldn’t gain much by being shaped to cut thin air, and it would lose a lot. For one thing, the launching process planned for the Platform allowed it to be built complete so far as its hull was concerned. Once it got out into its orbit there would be no more worries. There wouldn’t be any gamble on the practicability of assembling a great structure in a weightless “world.”
The two of them—and the way they both felt, it seemed natural for Joe to be helping Sally very carefully through the corridors of the Platform—the two of them came to the engine room. This wasn’t the place where the drive of the Platform was centered. It was where the service motors and the air-circulation system and the fluid pumps were powered. Off the engine room the main gyros were already installed. They waited only for the pilot gyros to control them as a steering engine controls an Earth ship’s rudder. Joe looked very thoughtfully at the gyro assembly. That was familiar, from the working drawings. But he let Sally guide him on without trying to stop and look closely.
She showed him the living quarters. They centered in a great open space sixty feet long and twenty wide and high. There were bookshelves, and two balconies, and chairs. Private cabins opened from it on different levels, but there were no steps to them. Yet there were comfortable chairs with straps so that when a man was weightless he could fasten himself in them. There were ash trays, ingeniously designed to look like exactly that and nothing else. But ashes would not fall into them, but would be drawn into them by suction. There was unpatterned carpet on the floor and on the ceiling.
“It’s going to feel queer,” said Sally, oddly quiet, “when all this is out in space, but it will look fairly normal. I think that’s important. This room will look like a big private library more than anything else. One won’t be reminded every second, by everything he sees, that he’s living in a strictly synthetic environment. He won’t feel cramped. If all the rooms were small, a man would feel as if he were in prison. At least this way he can pretend that things are normal.”
Her mind was not wholly on her words. She’d been frightened for Joe. And he was acutely aware of it, because he felt a pe
culiar after-effect himself.
“Normal,” he said drily, “except that he doesn’t weigh anything.”
“I’ve worried about that,” said Sally. “Sleeping’s going to be a big problem.”
“It’ll take getting used to,” Joe agreed.
There was a momentary pause. They were simply looking about the great room. Sally stirred uneasily.
“Tell me what you think,” she said. “You’ve been in an elevator that started to drop like a plummet. When the Platform is orbiting it’ll be like that all the time, only worse. No weight. Joe, if you were in an elevator that seemed to be dropping and dropping and dropping for hours on end—do you think you could go to sleep?”
Joe hadn’t thought about it. And he was acutely conscious of Sally, just then, but the idea startled him.
“It might be hard to adjust to,” he admitted.
“It’ll be hard to adjust to, awake,” said Sally. “But getting adjusted to it asleep should be worse. You’ve waked up from a dream that you’re falling?”
“Sure,” said Joe. Then he whistled. “Oh-oh! I see! You’d drop off to sleep, and you’d be falling. So you’d wake up. Everybody in the Platform will be falling around the Earth in the Platform’s orbit! Every time they doze off they’ll be falling and they’ll wake up!”
He managed to think about it. It was true enough. A man awake could remind himself that he only thought and felt that he was falling, and that there was no danger. But what would happen when he tried to sleep? Falling is the first fear a human being ever knows. Everybody in the world has at one time waked up gasping from a dream of precipices down which he plunged. It is an inborn terror. And no matter how thoroughly a man might know in his conscious mind that weightlessness was normal in emptiness, his conscious mind would go off duty when he went to sleep. A completely primitive subconscious would take over then, and it would not be satisfied. It might wake him frantically at any sign of dozing until he cracked up from sheer insomnia…or else let him sleep only when exhaustion produced unconsciousness rather than restful slumber.
