Rendezvous with Rama

“The reason of course, is that Rama hasn’t had time to warm up. It must have cooled down to near absolute zero—two hundred and seventy below—while it was in interstellar space. Now, as it approaches the sun, the outer hull is already almost as hot as molten lead. But the inside will stay cold, until the heat works its way through that kilometre of rock.”

“There’s some kind of fancy dessert with a hot exterior and ice-cream in the middle—I don’t remember what it’s called—”

“Baked Alaska. It’s a favourite at UP banquets, unfortunately.”

“Thank you, Sir Robert. That’s the situation in Rama at the moment, but it won’t last. All these weeks, the solar heat has been working its way through, and we expect a sharp temperature rise to begin in a few hours. That’s not the problem; by the time we’ll have to leave anyway, it will be no more than comfortably tropical.”

“Then what’s the difficulty?”

“I can answer in one word, Mr. Ambassador. Hurricanes.”

15. The Edge of the Sea

There were now more than twenty men and women inside Rama—six of them down on the plain, the rest ferrying equipment and expendables through the airlock system and down the stairway. The ship itself was almost deserted, with the minimum possible staff on duty; the joke went around that Endeavour was really being run by the four simps and that Goldie had been given the rank of Acting-Commander.

For these first explorations, Norton had established a number of ground rules; the most important dated back to the earliest days of man’s space faring. Every group, he had decided, must contain one person with prior experience. But not more than one. In that way, everybody would have an opportunity of learning as quickly as possible.

And so the first party to head for the Cylindrical Sea, though it was led by Surgeon-Commander Laura Ernst, had as its one-time veteran Lt. Boris Rodrigo, just back from Paris. The third member, Sergeant Pieter Rousseau, had been with the back-up teams at the Hub; he was an expert on space reco

From the foot of Stairway Alpha to the edge of the Sea was just under fifteen kilometres—or an Earth-equivalent of eight under the low gravity of Rama. Laura Ernst, who had to prove that she lived up to her own standards, set a brisk pace. They stopped for thirty minutes at the mid-way mark, and made the whole trip in a completely uneventful three hours.

It was also quite monotonous, walking forward in the beam of the searchlight through the anechoic darkness of Rama. As the pool of light advanced with them, it slowly elongated into a long, narrow ellipse; this foreshortening of the beam was the only visible sign of progress. If the observers up on the Hub had not given them continual distance checks, they could not have guessed whether they had travelled one kilometre, or five, or ten. They just plodded onwards through the million-year-old night, over an apparently seamless metal surface.

But at last, far ahead at the limits of the now-weakening beam, there was something new. On a normal world it would have been a horizon; as they approached, they could see that the plain on which they were walking came to an abrupt stop. They were nearing the edge of the Sea.

“Only a hundred metres,” said Hub Control. “Better slow down.”

That was hardly necessary, yet they had already done so. It was a sheer straight drop of fifty metres from the level of the plain to that of the Sea—if it was a sea, and not another sheet of that mysterious crystalline material. Although Norton had impressed upon everyone the danger of taking anything for granted in Rama, few doubted that the Sea was really made of ice. But for what conceivable reason was the cliff on the southern shore five hundred metres high, instead of the fifty here?

It was as if they were approaching the edge of the world; their oval of light, cut off abruptly ahead of them, became shorter and shorter. But far out on the curved screen of the Sea their monstrous foreshortened shadows had appeared, magnifying and exaggerating every movement. Those shadows had been their companions every step of the way, as they marched down the beam, but now that they were broken at the edge of the cliff they no longer seemed part of them. They might have been creatures of the Cylindrical Sea, waiting to deal with any intruders into their domain.

Because they were now standing on the edge of a fifty-metre cliff, it was possible for the first time to appreciate the curvature of Rama. But no one had ever seen a frozen lake bent upwards into a cylindrical surface; that was distinctly unsettling, and the eye did its best to find some other interpretation. It seemed to Dr. Ernst, who had once made a study of visual illusions, that half the time she was really looking at a horizontally curving bay, not a surface that soared up into the sky. It required a deliberate effort of will to accept the fantastic truth.

Only in the line directly ahead, parallel to the axis of Rama, was normalcy preserved. In this direction alone was there agreement between vision and logic. Here—for the next few kilometres at least—Rama looked flat, and was flat… And out there, beyond their distorted shadows and the outer limit of the beam, lay the island that dominated the Cylindrical Sea.

“Hub Control,” Dr. Ernst radioed, “please aim your beam at New York.”

The night of Rama fell suddenly upon them, as the oval of light went sliding out to sea. Conscious of the now invisible cliff at their feet, they all stepped back a few metres. Then, as if by some magical stage transformation, the towers of New York sprang into view.

The resemblance to old-time Manhattan was only superficial; this star-born echo of Earth’s past possessed its own unique identity. The more Dr. Ernst stared at it, the more certain she became that it was not a city at all.

The real New York, like all of Man’s habitations, had never been finished; still less had it been designed. This place, however, had an overall symmetry and pattern, though one so complex that it eluded the mind. It had been conceived and pla

The beam of the searchlight slowly tracked along those distant towers and domes and interlocked spheres and crisscrossed tubes. Sometimes there would be a brilliant reflection as some flat surface shot the light back towards them; the first time this happened, they were all taken by surprise. It was exactly as if, over there on that strange island, someone was signalling to them…

But there was nothing that they could see here that was not already shown in greater detail on photographs taken from the Hub. After a few minutes, they called for the light to return to them, and began to walk eastwards along the edge of the cliff. It had been plausibly theorized that, somewhere, there must surely be a flight of steps, or a ramp, leading down to the Sea. And one crewman, who was a keen sailor, had raised an interesting conjecture.

“Where there’s a sea,” Sergeant Ruby Barhes had predicted, “there must be docks and harbours—and ships. You can learn everything about a culture by studying the way it builds boats.” Her colleagues thought this a rather restricted point of view, but at least it was a stimulating one.

Dr. Ernst had almost given up the search, and was preparing to a descent by rope, when Lt. Rodrigo spotted the narrow stairway. It could easily have been overlooked in the shadowed darkness below the edge of the cliff, for there was no guardrail or other indication of its presence. And it seemed to lead nowhere; it ran down the fifty-metre vertical wall at a steep angle, and disappeared below the surface of the Sea.
