CHAPTER 1
"So this is the first time you've been upstairs?" said the pilot, leaning back idly in his seat so that it rocked to and fro in the gimbals. He clasped his hands behind his neck in a nonchalant manner that did nothing to reassure his passenger.
"Yes," said Martin Gibson, never taking his eyes from the chronometer as it ticked away the seconds.
"I thought so. You never got it quite right in your stories — all that nonsense about fainting under the acceleration. Why must people write such stuff? It's bad for business."
"I'm sorry," Gibson replied. "But I think you must be referring to my earlier stories. Space-travel hadn't got started then, and I had to use my imagination."
"Maybe," said the pilot grudgingly. (He wasn't paying the slightest attention to the instruments, and take-off was only two minutes away.) "It must be funny, I suppose, for this to be happening to you, after writing about it so often."
The adjective, thought Gibson, was hardly the one he would have used himself, but he saw the other's point of view. Dozens of his heroes — and villains — had gazed hypnotised by remorseless second-hands, waiting for the rockets to hurl them into infinity. And now — as it always did if one waited long enough — the reality had caught up with the fiction. The same moment lay only ninety seconds in his own future. Yes, it was funny, a beautiful case of poetic justice.
The pilot glanced at him, read his feelings, and grinned cheerfully.
"Don't let your own stories scare you. Why, I once took off standing up, just for a bet, though it was a damn silly thing to do."
"I'm not scared," Gibson replied with unnecessary emphasis.
"Hmmm," said the pilot, condescending to glance at the clock. The second-hand had one more circuit to go. "Then I shouldn't hold on to the seat like that. It's only beryl-manganese; you might bend it."
Sheepishly, Gibson relaxed. He knew that he was building up synthetic responses to the situation, but they seemed none the less real for all that.
"Of course," said the pilot, still at ease but now, Gibson noticed, keeping his eyes fixed on the instrument panel, "it wouldn't be very comfortable if it lasted more than a few minutes — ah, there go the fuel pumps. Don't worry when the vertical starts doing funny things, but let the seat swing where it likes. Shut your eyes if that helps at all. (Hear the igniter jets start then?) We take about ten seconds to build up to full thrust — there's really nothing to it, apart from the noise. You just have to put up with that. I SAID, YOU JUST HAVE TO PUT UP WITH THAT!"
But Martin Gibson was doing nothing of the sort. He had already slipped gracefully into unconsciousness at an acceleration that had not yet exceeded that of a high-speed elevator.
He revived a few minutes and a thousand kilometres1 later, feeling quite ashamed of himself. A beam of sunlight was shining full on his face, and he realised that the protective shutter on the outer hull must have slid aside. Although brilliant, the light was not as intolerably fierce as he would have expected; then he saw that only a fraction of the full intensity was filtering through the deeply tinted glass.
He looked at the pilot, hunched over his instrument board and busily writing up the log. Everything was very quiet, but from time to time there would come curiously muffled reports — almost miniature explosions — that Gibson found disconcerting. He coughed gently to announce his return to consciousness, and asked the pilot what they were.
"Thermal contraction in the motors," he replied briefly. "They've been running round five thousand degrees and cool mighty fast. You feeling all right now?"
"I'm fine," Gibson answered, and meant it. "Shall I get up?"
Psychologically, he had hit the bottom and bounced back. It was a very unstable position, though he did not realise it.
"If you like," said the pilot doubtfully. "But be careful — hang on to something solid."
Gibson felt a wonderful sense of exhilaration. The moment he had waited for all his life had come. He was in space! It was too bad that he'd missed the take-off, but he'd gloss that part over when he wrote it up.
From a thousand kilometres away, Earth was still very large — and something of a disappointment. The reason was quickly obvious. He had seen so many hundreds of rocket photographs and films that the surprise had been spoilt; he knew exactly what to expect. There were the inevitable moving bands of cloud on their slow march round the world. At the centre of the disc, the divisions between land and sea were sharply defined, and an infinite amount of minute detail was visible, but towards the horizon everything was lost in the thickening haze. Even in the cone of clear vision vertically beneath him, most of the features were unrecognisable and therefore meaningless. No doubt a meteorologist would have gone into transports of delight at the animated weather-map displayed below — but most of the meteorologists were up in the space stations, anyway, where they had an even better view. Gibson soon grew tired of searching for cities and other works of man. It was chastening to think that all the thousands of years of human civilisation had produced no appreciable change in the panorama below.
Then Gibson began to look for the stars, and met his second disappointment. They were there, hundreds of them, but pale and wan, mere ghosts of the blinding myriads he had expected to find. The dark glass of the port was to blame; in subduing the sun, it had robbed the stars of all their glory.
Gibson felt a vague annoyance. Only one thing had turned out quite as expected. The sensation of floating in mid-air, of being able to propel oneself from wall to wall at the touch of a finger, was just as delightful as he had hoped — though the quarters were too cramped for any ambitious experiments. Weightlessness was an enchanting, a fairy-like state, now that there were drugs to immobilise the balance organs and space-sickness was a thing of the past. He was glad of that. How his heroes had suffered! (His heroines too, presumably, but one never mentioned that.) He remembered Robin Blake's first flight, in the original version of "Martian Dust." When he'd written that, he had been heavily under the influence of D. H. Lawrence. (It would be interesting, one day, to make a list of the authors who hadn't influenced him at one time or another.)
There was no doubt that Lawrence was magnificent at describing physical sensations, and quite deliberately Gibson had set out to defeat him on his own ground. He had devoted a whole chapter to space-sickness, describing every symptom from the queasy premonitions that could sometimes be willed aside, the subterranean upheavals that even the most optimistic could no longer ignore, the volcanic cataclysms of the final stages and the ultimate, merciful exhaustion.
The chapter had been a masterpiece of stark realism. It was too bad that his publishers, with an eye on a squeamish Book-of-the-Month Club, had insisted on removing it. He had put a lot of work into that chapter; while he was writing it, he had really lived those sensations. Even now —

"It's very puzzling," said the M.O. thoughtfully as the now quiescent author was propelled through the airlock. "He's passed his medical tests O.K., and of course he'll have had the usual injections before leaving Earth. It must be psychosomatic."
"I don't care what it is," complained the pilot bitterly, as he followed the cortege into the heart of Space Station One. "All I want to know is — who's going to clean up my ship?"
No one seemed inclined to answer this heart-felt question, least of all Martin Gibson, who was only vaguely conscious of white walls drifting by his field of vision. Then, slowly, there was a sensation of increasing weight, and a warm, caressing glow began to steal through his limbs. Presently he became fully aware of his surroundings. He was in a hospital ward, and a battery of infrared lamps was bathing him with a glorious, enervating warmth, that sank through his flesh to the very bones.
"Well?" said the medical officer presently.
Gibson grinned feebly.
"I'm sorry about this. Is it going to happen again?"
"I don't know how it happened the first time. It's very unusual; the drugs we have now are supposed to be infallible."
"I think it was my own fault," said Gibson apologetically. "You see, I've got a rather powerful imagination, and I started thinking about the symptoms of space-sickness — in quite an objective sort of way, of course — but before I knew what had happened —"
"Well, just stop it!" ordered the doctor sharply. "Or we'll have to send you right back to Earth. You can't do this sort of thing if you're going to Mars. There wouldn't be much left of you after three months."
A shudder passed through Gibson's tortured frame. But he was rapidly recovering, and already the nightmare of the last hour was fading into the past.
"I'll be O.K.," he said. "Let me out of this muffle-furnace before I cook."
A little unsteadily, he got to his feet. It seemed strange, here in space, to have normal weight again. Then he remembered that Station One was spinning on its axis, and the living quarters were built around the outer walls so that centrifugal force could give the illusion of gravity.
The great adventure, he thought ruefully, hadn't started at all well. But he was determined not to be sent home in disgrace. It was not merely a question of his own pride: the effect on his public and his reputation would be deplorable. He winced as he visualised the headlines: "GIBSON GROUNDED! SPACE-SICKNESS ROUTS AUTHOR-ASTRONAUT." Even the staid literary weeklies would pull his leg, and as for "Time" — no, it was unthinkable!
"It's lucky," said the M.O., "that we've got twelve hours before the ship leaves. I'll take you into the zero-gravity section and see how you manage there, before I give you a clean bill of health."
Gibson also thought that was a good idea. He had always regarded himself as fairly fit, and until now it had never seriously occurred to him that this journey might be not merely uncomfortable but actually dangerous. You could laugh at space-sickness — when you'd never experienced it yourself. Afterwards, it seemed a very different matter.
The Inner Station — "Space Station One," as it was usually called — was just over two thousand kilometres from Earth, circling the planet every two hours. It had been Man's first stepping-stone to the stars, and though it was no longer technically necessary for spaceflight, its presence had a profound effect on the economics of interplanetary travel. All journeys to the Moon or the planets started from here; the unwieldy atomic ships floated alongside this outpost of Earth while the cargoes from the parent world were loaded into their holds. A ferry service of chemically fuelled rockets linked the station to the planet beneath, for by law no atomic drive unit was allowed to operate within a thousand kilometres of the Earth's surface. Even this safety margin was felt by many to be inadequate, for the radioactive blast of a nuclear propulsion unit could cover that distance in less than a minute.
Space Station One had grown with the passing years, by a process of accretion, until its original designers would never have recognised it. Around the central spherical core had accumulated observatories, communications labs with fantastic aerial systems, and mazes of scientific equipment which only a specialist could identify. But despite all these additions, the main function of the artificial moon was still that of refuelling the little ships with which Man was challenging the immense loneliness of the Solar System.
"Quite sure you're feeling O.K. now?" asked the doctor as Gibson experimented with his feet.
"I think so," he replied, unwilling to commit himself.
"Then come along to the reception room and we'll get you a drink — a nice hot drink," he added, to prevent any misunderstanding. "You can sit there and read the paper for half an hour before we decide what to do with you."
It seemed to Gibson that anticlimax was being piled on anticlimax. He was two thousand kilometres from Earth, with the stars all around him; yet here he was forced to sit sipping sweet tea — tea! — in what might have been an ordinary dentist's waiting-room. There were no windows, presumably because the sight of the rapidly revolving heavens might have undone the good work of the medical staff. The only way of passing the time was to skim through piles of magazines which he'd already seen, and which were difficult to handle as they were ultra-light-weight editions apparently printed on cigarette paper. Fortunately he found a very old copy of "Argosy" containing a story he had written so long ago that he had completely forgotten the ending, and this kept him happy until the doctor returned.
"Your pulse seems normal," said the M.O. grudgingly. "We'll take you along to the zero-gravity chamber. Just follow me and don't be surprised at anything that happens."
With this cryptic remark he led Gibson out into a wide, brightly lit corridor that seemed to curve upwards in both directions away from the point at which he was standing. Gibson had no time to examine this phenomenon, for the doctor slid open a side door and started up a flight of metal stairs. Gibson followed automatically for a few paces, then realised just what lay ahead of him and stopped with an involuntary cry of amazement.
Immediately beneath his feet, the slope of the stairway was a reasonable forty-five degrees, but it rapidly became steeper until only a dozen metres ahead the steps were rising vertically. Thereafter — and it was a sight that might have unnerved anyone coming across it for the first time — the increase of gradient continued remorselessly until the steps began to overhang and at last passed out of sight above and behind him.
Hearing his exclamation, the doctor looked back and gave a reassuring laugh.
"You mustn't always believe your eyes," he said. "Come along and see how easy it is."
Reluctantly Gibson followed, and as he did so he became aware that two very peculiar things were happening. In the first place he was gradually becoming lighter; in the second, despite the obvious steepening of the stairway, the slope beneath his feet remained at a constant forty-five degrees. The vertical direction itself, in fact, was slowly tilting as he moved forward, so that despite its increasing curvature the gradient of the stairway never altered.
It did not take Gibson long to arrive at the explanation. All the apparent gravity was due to the centrifugal force produced as the station spun slowly on its axis, and as he approached the centre the force was diminishing to zero. The stairway itself was winding in towards the axis along some sort of spiral — once he'd have known its mathematical name — so that despite the radial gravity field the slope underfoot remained constant. It was the sort of thing that people who lived in space stations must get accustomed to quickly enough; presumably when they returned to Earth the sight of a normal stairway would be equally unsettling.
At the end of the stairs there was no longer any real sense of "up" or "down." They were in a long cylindrical room, criss-crossed with ropes but otherwise empty, and at its far end a shaft of sunlight came blasting through an observation port. As Gibson watched, the beam moved steadily across the metal walls like a questing searchlight, was momentarily eclipsed, then blazed out again from another window. It was the first indication Gibson's senses had given him of the fact that the station was really spinning on its axis, and he timed the rotation roughly by noting how long the sunlight took to return to its original position. The "day" of this little artificial world was less than ten seconds; that was sufficient to give a sensation of normal gravity at its outer walls.
Gibson felt rather like a spider in its web as he followed the doctor hand-over-hand along the guide ropes, towing himself effortlessly through the air until they came to the observation post. They were, he saw, at the end of a sort of chimney jutting out along the axis of the station, so that they were well clear of its equipment and apparatus and had an almost unrestricted view of the stars.
"I'll leave you here for a while," said the doctor. "There's plenty to look at, and you should be quite happy. If not — well, remember there's normal gravity at the bottom of those stairs!"
