  'Well, can we?'

  'Yes, if we proceed with caution. Karl and I have worked out a very conservative profile—based on the assumption that we can dispense with breathing gear below Level Two. Of course, that's an incredible stroke of luck, and changes the whole logistics picture. I still can't get used to the idea of a world with oxygen … So we only need to supply food and water and thermosuits, and we're in business. Going down will be easy; it looks as if we can slide most of the way, on that very convenient banister.'

  'I've got Chips working on a sled with parachute braking. Even if we can't risk it for crew, we can use it for stores and equipment.'

  'Fine; that should do the trip in ten minutes; otherwise it will take about an hour. Climbing up is harder to estimate; I'd like to allow six hours, including two one-hour periods. Later, as we get experience—and develop some muscles—we may be able to cut this back considerably.'

  'What about psychological factors?'

  'Hard to assess, in such a novel environment. Darkness may be the biggest problem.'

  'I'll establish searchlights on the Hub. Besides its own lamps, any party down there will always have a beam playing on it.'

  'Good—that should be a great help.'

  'One other point: should we play safe and send a party only halfway down the stair—and back—or should we go the whole way on the first attempt?'

  'If we had plenty of time, I'd be cautious. But time is short, and I can see no danger in going all the way—and looking around when we get there.'

  'Thanks, Laura—that's all I want to know. I'll get the Exec working on the details. And I'll order all hands to the centrifuge—twenty minutes a day at half a gee. Will that satisfy you?'

  'No. It's point six gee down there in Rama, and I want a safety margin. Make it three quarters—'

  'Ouch!'

  '—for ten minutes—'

  'I'll settle for that—'

  '—twice a day.'

  'Laura, you're a cruel, hard woman. But so be it. I'll break the news just before dinner. That should spoil a few appetites.'

  It was the first time that Commander Norton had ever seen Karl Mercer slightly ill at ease. He had spent the fifteen minutes discussing the logistics problem in his usual competent manner, but something was obviously worrying him. His captain, who had a shrewd idea of what it was, waited patiently until he brought it out.

  'Skipper,' Karl said at length, 'are you sure you should lead this party? If anything goes wrong, I'm considerably more expendable. And I've been further inside Rama than anyone else—even if only by fifty metres.'

  'Granted. But it's time the commander led his troops, and we've decided that there's no greater risk on this trip than on the last. At the first sign of trouble, I'll be back up that stairway fast enough to qualify for the Lunar Olympics.'

  He waited for any further objections, but none came, though Karl still looked unhappy. So he took pity on him and added gently: 'And I bet Joe will beat me to the top.'

  The big man relaxed, and a slow grin spread across his face. 'All the same, Bill, I wish you'd taken someone else.'

  'I wanted one man who'd been down before, and we can't both go. As for Herr Doctor Professor Sergeant Myron, Laura says he's still two kilos overweight. Even shaving off that moustache didn't help.'

  'Who's your number three?'

  'I still haven't decided. That depends on Laura.'

  'She wants to go herself.'

  'Who doesn't? But if she turns up at the top of her own fitness list, I'll be very suspicious.'

  As Lieut-Commander Mercer gathered up his papers and launched himself out of the cabin, Norton felt a brief stab of envy. Almost all the crew—about eighty-five per cent, by his minimum estimate—had worked out some sort of emotional accommodation. He had known ships where the captain had done the same, but that was not his way. Though discipline aboard the Endeavour was based very largely on the mutual respect between highly trained and intelligent men and women, the commander needed something more to underline his position. His responsibility was unique, and demanded a certain degree of isolation, even from his closest friends. Any liaison could be damaging to morale, for it was almost impossible to avoid charges of favouritism. For this reason, affairs spanning more than two degrees of rank were firmly discouraged; but apart from this, the only rule regulating shipboard sex was 'So long as they don't do it in the corridors and frighten the simps'.

  There were four superchimps aboard Endeavour, though strictly speaking the name was inaccurate, because the ship's non-human crew was not based on chimpanzee stock. In zero gravity, a prehensile tail is an enormous advantage, and all attempts to supply these to humans had turned into embarrassing failures. After equally unsatisfactory results with the great apes, the Superchimpanzee Corporation had turned to the monkey kingdom.

  Blackie, Blondie, Goldie and Brownie had family trees whose branches included the most intelligent of the Old and New World monkeys, plus synthetic genes that had never existed in nature. Their rearing and education had probably cost as much as that of the average spaceman, and they were worth it. Each weighed less than thirty kilos and consumed only half the food and oxygen of a human being, but each could replace 2.75 men for housekeeping, elementary cooking, tool-carrying and dozens of other routine jobs.

  That 2.75 was the Corporation's claim, based on innumerable time-and-motion studies. The figure, though surprising and frequently challenged, appeared to be accurate, for simps were quite happy to work fifteen hours a day and did not get bored by the most menial and repetitious tasks. So they freed human beings for human work; and on a spaceship, that was a matter of vital importance.

  Unlike the monkeys who were their nearest relatives Endeavour's simps were docile, obedient and uninquisitive. Being cloned, they were also sexless, which eliminated awkward behavioural problems. Carefully housetrained vegetarians, they were very clean and didn't smell; they would have made perfect pets, except that nobody could possibly have afforded them.

  Despite these advantages, having simps on board involved certain problems. They had to have their own quarters—inevitably labelled 'The Monkey House'. Their little mess-room was always spotless, and was well equipped with TV, games equipment and programmed teaching machines. To avoid accidents, they were absolutely forbidden to enter the ship's technical areas; the entrances to all these were colour-coded in red, and the simps were conditioned so that it was psychologically impossible for them to pass the visual barriers.

  There was also a communications problem. Though they had an equivalent IQ of sixty, and could understand several hundred words of English, they were unable to talk. It had proved impossible to give useful vocal chords either to apes or monkeys, and they therefore had to express themselves in sign language.

  The basic signs were obvious and easily learned, so that everyone on board ship could understand routine messages. But the only man who could speak fluent Simpish was their handler—Chief Steward McAndrews.

  It was a standing joke that Sergeant Ravi McAndrews looked rather like a simp—which was hardly an insult, for with their short, tinted pelts and graceful movements they were very handsome animals. They were also affectionate, and everyone on board had his favourite; Commander Norton's was the aptly-named Goldie.

  But the warm relationship which one could so easily establish with simps created another problem, often used as a powerful argument against their employment in space. Since they could only be trained for routine, low-grade tasks, they were worse than useless in an emergency; they could then be a danger to themselves and to their human companions. In particular, teaching them to use spacesuits had proved impossible, the concepts involved being quite beyond their understanding.

  No one liked to talk about it, but everybody knew what had to be done if a hull was breached or the order came to abandon ship. It had happened only once; then the simp handler had carried out his instructions more than adequately. He was found with his charges, killed by the same poison. T
hereafter the job of euthing was transferred to the chief medical officer, who it was felt would have less emotional involvement.

  Norton was very thankful that this responsibility, at least, did not fall upon the captain's shoulders. He had known men he would have killed with far fewer qualms than he would Goldie.

  CHAPTER 12

  THE STAIRWAY OF THE GODS

  IN THE CLEAR, cold atmosphere of Rama, the beam of the searchlight was completely invisible. Three kilometres down from the central Hub, the hundred-metre wide oval of light lay across a section of that colossal stairway. A brilliant oasis in the surrounding darkness, it was sweeping slowly towards the curved plain still five kilometres below; and in its centre moved a trio of antlike figures, casting long shadows before them.

  It had been, just as they had hoped and expected, a completely uneventful descent. They had paused briefly at the first platform, and Norton had walked a few hundred metres along the narrow, curving ledge before starting the slide down to the second level. Here they had discarded their oxygen gear, and revelled in the strange luxury of being able to breathe without mechanical aids. Now they could explore in comfort, freed from the greatest danger that confronts a man in space, and forgetting all worries about suit integrity and oxygen reserve.

  By the time they had reached the fifth level, and there was only one more section to go, gravity had reached almost half its terrestrial value. Rama's centrifugal spin was at last exerting its real strength; they were surrendering themselves to the implacable force which rules every planet, and which can exert a merciless price for the smallest slip. It was still very easy to go downwards; but the thought of the return, up those thousands upon thousands of steps, was already beginning to prey upon their minds.

  The stairway had long ago ceased its vertiginous downward plunge and was now flattening out towards the horizontal. The gradient was now only about 1 in 5; at the beginning, it had been 5 in 1. Normal walking was now both physically, and psychologically, acceptable; only the lowered gravity reminded them that they were not descending some great stairway on Earth. Norton had once visited the ruins of an Aztec temple, and the feelings he had then experienced came echoing back to him—amplified a hundred times. Here was the same sense of awe and mystery, and the sadness of the irrevocably vanished past. Yet the scale here was so much greater, both in time and space, that the mind was unable to do it justice; after a while, it ceased to respond. Norton wondered if, sooner or later, he would take even Rama for granted.

  And there was another respect in which the parallel with terrestrial ruins failed completely. Rama was hundreds of times older than any structure that had survived on Earth—even the Great Pyramid. But everything looked absolutely new; there was no sign of wear and tear.

  Norton had puzzled over this a good deal, and had arrived at a tentative explanation. Everything that they had so far examined was part of an emergency back-up system, very seldom put to actual use. He could not imagine that the Ramans—unless they were physical fitness fanatics of the kind not uncommon on Earth—ever walked up and down this incredible stairway, or its two identical companions completing the invisible Y far above his head. Perhaps they had only been required during the actual construction of Rama, and had served no purpose since that distant day. That theory would do for the moment, yet it did not feel right. There was something wrong, somewhere…

  They did not slide for the last kilometre but went down the steps two at a time in long, gentle strides; this way, Norton decided, they would give more exercise to muscles that would soon have to be used. And so the end of the stairway came upon them almost unawares; suddenly, there were no more steps—only a flat plain, dull grey in the now weakening beam of the Hub searchlight, fading away into the darkness a few hundred metres ahead.

  Norton looked back along the beam, towards its source up on the axis more than eight kilometres away. He knew that Mercer would be watching through the telescope, so he waved to him cheerfully.

  'Captain here,' he reported over the radio. 'Everyone in fine shape—no problems. Proceeding as planned.'

  'Good,' replied Mercer. 'We'll be watching.'

  There was a brief silence; then a new voice cut in. 'This is the Exec, on board ship. Really, Skipper, this isn't good enough. You know the news services have been screaming at us for the last week. I don't expect deathless prose, but can't you do better than that?'

  'I'll try,' Norton chuckled. 'But remember there's nothing to see yet. It's like … well … being on a huge, darkened stage, with a single spotlight. The first few hundred steps of the stairway rise out of it until they disappear into the darkness overhead. What we can see of the plain looks perfectly flat. The curvature's too small to be visible over this limited area. And that's about it.'

  'Like to give any impressions?'

  'Well, it's still very cold—below freezing—and we're glad of our thermosuits. And quiet of course; quieter than anything I've ever known on Earth, or in space, where there's always some background noise. Here, every sound is swallowed up; the space around us is so enormous that there aren't any echoes. It's weird, but I hope we'll get used to it.'

  'Thanks, Skipper. Anyone else—Joe, Boris?'

  Lt. Joe Calvert, never at a loss for words, was happy to oblige.

  'I can't help thinking that this is the first time—ever—that we've been able to walk on another world, breathing its natural atmosphere—though I suppose "natural" is hardly the word you can apply to a place like this. Still, Rama must resemble the world of its builders; our own spaceships are all miniature earths. Two examples are damned poor statistics, but does this mean that all intelligent life forms are oxygen eaters? What we've seen of their work suggests that the Ramans were humanoid, though perhaps about fifty per cent taller than we are. Wouldn't you agree, Boris?'

  Is Joe teasing Boris? Norton asked himself. I wonder how he's going to react?…

  To all his shipmates, Boris Rodrigo was something of an enigma. The quiet, dignified communications officer was popular with the rest of the crew, but he never entered fully into their activities and always seemed a little apart—marching to the music of a different drummer.

  As indeed he was, being a devout member of the Fifth Church of Christ Cosmonaut. Norton had never been able to discover what had happened to the earlier four, and he was equally in the dark about the Church's rituals and ceremonies. But the main tenet of its faith was well known: it believed that Jesus Christ was a visitor from space, and had constructed an entire theology on that assumption.

  It was perhaps not surprising that an unusually high proportion of the Church's devotees worked in space in some capacity or other. Invariably, they were efficient, conscientious and absolutely reliable. They were universally respected and even liked, especially as they made no attempt to convert others. Yet there was also something slightly spooky about them; Norton could never understand how men with advanced scientific and technical training could possibly believe some of the things he had heard Christers state as incontrovertible facts.

  As he waited for Lt. Rodrigo to answer Joe's possibly loaded question, the commander had a sudden insight into his own hidden motives. He had chosen Boris because he was physically fit, technically qualified, and completely dependable. At the same time, he wondered if some part of his mind had not selected the lieutenant out of an almost mischievous curiosity. How would a man with such religious beliefs react to the awesome reality of Rama? Suppose he encountered something that confounded his theology . . . or, for that matter, confirmed it?

  But Boris Rodrigo, with his usual caution, refused to be drawn.

  'They were certainly oxygen breathers, and they could be humanoid. But let's wait and see. With any luck, we should discover what they were like. There may be pictures, statues—perhaps even bodies, over in those towns. If they are towns.'

  'And the nearest is only eight kilometres away,' said Joe Calvert hopefully.

  Yes, thought the commander, but it's also eight kilometres
back—and then there's that overwhelming stairway to climb again. Can we take the risk?

  A quick sortie to the 'town' which they had named Paris had been among the first of his contingency plans, and now he had to make his decision. They had ample food and water for a stay of twenty-four hours; they would always be in full view of the back-up team on the Hub, and any kind of accident seemed virtually impossible on this smooth, gently curving, metal plain. The only foreseeable danger was exhaustion; when they got to Paris, which they could do easily enough, could they do more than take a few photographs and perhaps collect some small artifacts, before they had to return?

  But even such a brief foray would be worth it; there was so little time, as Rama hurtled sunwards towards a perihelion too dangerous for Endeavour to match.

  In any case, part of the decision was not his to make. Up in the ship, Dr. Ernst would be watching the outputs of the bio-telemetering sensors attached to his body. If she turned thumbs-down, that would be that.

  'Laura, what do you think?'

  'Take thirty minutes' rest, and a five hundred calorie energy module. Then you can start.'

  'Thanks, Doc,' interjected Joe Calvert. 'Now I can die happy. I always wanted to see Paris. Montmartre, here we come.'

  CHAPTER 13

  THE PLAIN OF RAMA

  AFTER THOSE INTERMINABLE stairs, it was a strange luxury to walk once more on a horizontal surface. Directly ahead, the ground was indeed completely flat; to right and left, at the limits of the floodlit area, the rising curve could just be detected. They might have been walking along a very wide, shallow valley; it was quite impossible to believe that they were really crawling along the inside of a huge cylinder, and that beyond this little oasis of light the land rose up to meet—no, to become—the sky.

  Though they all felt a sense of confidence and subdued excitement, after a while the almost palpable silence of Rama began to weigh heavily upon them. Every footstep, every word, vanished instantly into the unreverberant void; after they had gone little more than half a kilometre Lt. Calvert could stand it no longer.
