Tales of Ten Worlds Page 3

  The attack came without warning, as it usually did. Quite suddenly, Icarus no longer seemed to be beneath him, the stars no longer above. The universe tilted through a right angle; he was moving straight up a vertical cliff, like a mountaineer scaling a rock face, and though Sherrard's reason told him that this was pure illusion, all his senses screamed that it was true. In a moment gravity must drag him off this sheer wall, and he would drop down mile upon endless mile until he smashed into oblivion.

  Worse was to come; the false vertical was still swinging like a compass needle that had lost the pole. Now he was on the underside of an immense rocky roof, like a fly clinging to a ceiling; in another moment it would have become a wall again— but this time he would be moving straight down it, instead of up. . . .

  He had lost all control over the pod, and the clammy sweat that had begun to dew his brow warned him that he would soon lose control over his body. There was only one thing to do; he clenched his eyes tightly shut, squeezed as far back as possible into the tiny closed world of the capsule, and pretended with all his might that the universe outside did not exist. He did not even allow the slow, gentle crunch of his second crash to interfere with his self-hypnosis.

  When he again dared to look outside, he found that the pod had come to rest against a large boulder. Its mechanical arms had broken the force of the impact, but at a cost that was more than he could afford to pay. Though the capsule was virtually weightless here, it still possessed its normal five hundred pounds of inertia, and it had been moving at perhaps four miles an hour. The momentum had been too much for the metal arms to absorb; one had snapped, and the other was hopelessly bent.

  When he saw what had happened, Sherrard's first reaction was not despair, but anger. He had been so certain of success when the pod had started its glide across the barren face of Icarus. And now this, all through a moment of physical weakness! But space made no allowance for human frailties or emotions, and a man who did not accept that fact had no right to be here.

  At least he had gained precious time in his pursuit of the ship; he had put an extra ten minutes, if not more, between himself and dawn. Whether that ten minutes would merely prolong the agony or whether it would give his shipmates the extra time they needed to find him, he would soon know.

  Where were they? Surely they had started the search by now! He strained his eyes toward the brilliant star of the ship, hoping to pick out the fainter lights of space-pods moving toward him—but nothing else was visible against the slowly turning vault of heaven.

  He had better look to his own resources, slender though they were. Only a few minutes were left before the Prometheus and her trailing lights would sink below the edge of the asteroid and leave him in darkness. It was true that the darkness would be all too brief, but before it fell upon him he might find some shelter against the coming day. This rock into which he had crashed, for example. . . .

  Yes, it would give some shade, until the sun was halfway up the sky. Nothing could protect him if it passed right overhead, but it was just possible that he might be in a latitude where the sun never rose far above the horizon at this season of Icarus' four-hundred-and-nine-day year. Then he might survive the brief period of daylight; that was his only hope, if the rescuers did not find him before dawn.

  There went Prometheus and her lights, below the edge of the world. With her going, the now-unchallenged stars blazed forth with redoubled brilliance. More glorious than any of them—so lovely that even to look upon it almost brought tears to his eyes—was the blazing beacon of Earth, with its companion moon beside it. He had been born on one, and had walked on the other; would he see either again?

  Strange that until now he had given no thought to his wife and children, and to all that he loved in the life that now seemed so far away. He felt a spasm of guilt, but it passed swiftly. The ties of affection were not weakened, even across the hundred million miles of space that now sundered him from his family. At this moment, they were simply irrelevant. He was now a primitive, self-centered animal fighting for his life, and his only weapon was his brain. In this conflict, there was no place for the heart; it would merely be a hindrance, spoiling his judgment and weakening his resolution.

  And then he saw something that banished all thoughts of his distant home. Reaching up above the horizon behind him, speeding across the stars like a milky mist, was a faint and ghostly cone of phosphorescence. It was the herald of the sun— the beautiful, pearly phantom of the corona, visible on Earth only during the rare moments of a total eclipse. When the corona was rising, the sun would not be far behind, to smite this little land with fury.

  Sherrard made good use of the warning. Now he could judge, with some accuracy, the exact point where the sun would rise. Crawling slowly and clumsily on the broken stumps of his metal arms, he dragged the capsule round to the side of the boulder that should give the greatest shade. He had barely reached it when the sun was upon him like a beast of prey, and his tiny world exploded into light.

  He raised the dark filters inside his helmet, one thickness after another, until he could endure the glare. Except where the broad shadow of the boulder lay across the asteroid, it was like looking into a furnace. Every detail of the desolate land around him was revealed by that merciless light; there were no greys, only blinding whites and impenetrable blacks. All the shadowed cracks and hollows were pools of ink, while the higher ground already seemed to be on fire, as it caught the sun. Yet it was only a minute after dawn.

  Now Sherrard could understand how the scorching heat of a billion summers had turned Icarus into a cosmic cinder, baking the rocks until the last traces of gas had bubbled out of them. Why should men travel, he asked himself bitterly, across the gulf of stars at such expense and risk—merely to land on a spinning slag heap? For the same reason, he knew, that they had once struggled to reach Everest and the Poles and the far places of the Earth—for the excitement of the body that was adventure, and the more enduring excitement of the mind that was discovery. It was an answer that gave him little consolation, now that he was about to be grilled like a joint on the turning spit of Icarus.

  Already he could feel the first breath of heat upon his face. The boulder against which he was lying gave him protection from direct sunlight, but the glare reflected back at him from those blazing rocks only a few yards away was striking through the transparent plastic of the dome. It would grow swiftly more intense as the sun rose higher; he had even less time than he had thought, and with the knowledge came a kind of numb resignation that was beyond fear. He would wait—if he could—until the sunrise engulfed him and the capsule's cooling unit gave up the unequal struggle; then he would crack the pod and let the air gush out into the vacuum of space.

  Nothing to do but to sit and think in the minutes that were left to him before his pool of shadow contracted. He did not try to direct his thoughts, but let them wander where they willed. How strange that he should be dying now, because back in the nineteen-forties—years before he was born—a man at Palomar had spotted a streak of light on a photographic plate, and had named it so appropriately after the boy who flew too near the sun.

  One day, he supposed, they would build a monument here for him on this blistered plain. What would they inscribe upon it? "Here died Colin Sherrard, astronics engineer, in the cause of Science." That would be funny, for he had never understood half the things that the scientists were trying to do.

  Yet some of the excitement of their discoveries had communicated itself to him. He remembered how the geologists had scraped away the charred skin of the asteroid, and had polished the metallic surface that lay beneath. It had been covered with a curious pattern of lines and scratches, like one of the abstract paintings of the Post-Picasso Decadents. But these lines had some meaning; they wrote the history of Icarus, though only a geologist could read it. They revealed, so Sherrard had been told, that this lump of iron and rock had not always floated alone in space. At some remote time in the past, it had been under enormous p
ressure—and that could mean only one thing. Billions of years ago it had been part of a much larger body, perhaps a planet like Earth. For some reason that planet had blown up, and Icarus and all the thousands of other asteroids were the fragments of that cosmic explosion.

  Even at this moment, as the incandescent line of sunlight came closer, this was a thought that stirred his mind. What Sherrard was lying upon was the core of a world—perhaps a world that had once known life. In a strange, irrational way it comforted him to know that his might not be the only ghost to haunt Icarus until the end of time.

  The helmet was misting up; that could only mean that the cooling unit was about to fail. It had done its work well; even now, though the rocks only a few yards away must be glowing a sullen red, the heat inside the capsule was not unendurable. When failure came, it would be sudden and catastrophic.

  He reached for the red lever that would rob the sun of its prey—but before he pulled it, he would look for the last time upon Earth. Cautiously, he lowered the dark filters, adjusting them so that they still cut out the glare from the rocks, but no longer blocked his view of space.

  The stars were faint now, dimmed by the advancing glow of the corona. And just visible over the boulder whose shield would soon fail him was a stub of crimson flame, a crooked finger of fire jutting from the edge of the sun itself. He had only seconds left.

  There was the Earth, there was the moon. Good-by to them both, and to his friends and loved ones on each of them. While he was looking at the sky, the sunlight had begun to lick the base of the capsule, and he felt the first touch of fire. In a reflex as automatic as it was useless, he drew up his legs, trying to escape the advancing wave of heat.

  What was that? A brilliant flash of light, infinitely brighter than any of the stars, had suddenly exploded overhead. Miles above him, a huge mirror was sailing across the sky, reflecting the sunlight as it slowly turned through space. Such a thing was utterly impossible; he was beginning to suffer from hallucinations, and it was time he took his leave. Already the sweat was pouring from his body, and in a few seconds the capsule would be a furnace.

  He waited no longer, but pulled on the Emergency Release with all his waning strength, bracing himself at the same moment to face the end.

  Nothing happened; the lever would not move. He tugged it again and again before he realized that it was hopelessly jammed. There was no easy way out for him, no merciful death as the air gushed from his lungs. It was then, as the true terror of his situation stuck home to him, that his nerve finally broke and he began to scream like a trapped animal.

  When he heard Captain McClellan's voice speaking to him, thin but clear, he knew that it must be another hallucination.

  Yet some last remnant of discipline and self-control checked his screaming; he clenched his teeth and listened to that familiar, commanding voice.

  "Sherrard! Hold on, man! We've got a fix on you—but keep shouting!"

  "Here I am!" he cried, "but hurry, for God's sake! I'm burning!"

  Deep down in what was left of his rational mind he realized what had happened. Some feeble ghost of a signal was leaking through the broken stubs of his antennas, and the searchers had heard his screams—as he was hearing their voices. That meant they must be very close indeed, and the knowledge gave him sudden strength.

  He stared through the steaming plastic of the dome, looking once more for that impossible mirror in the sky. There it was again—and now he realized that the baffling perspectives of space had tricked his senses. The mirror was not miles away, nor was it huge. It was almost on top of him, and it was moving fast.

  He was still shouting when it slid across the face of the rising sun, and its blessed shadow fell upon him like a cool wind that had blown out of the heart of winter, over leagues of snow and ice. Now that it was so close, he recognized it at once; it was merely a large metal-foil radiation screen, no doubt hastily snatched from one of the instrument sites. In the safety of its shadow, his friends had been searching for him.

  A heavy-duty, two-man capsule was hovering overhead, holding the glittering shield in one set of arms and reaching for him with the other. Even through the misty dome and the haze of heat that still sapped his senses, he recognized Captain McClellan's anxious face, looking down at him from the other pod.

  So this was what birth was like, for truly he had been reborn. He was too exhausted for gratitude—that would come later—but as he rose from the burning rocks his eyes sought and found the bright star of Earth. "Here I am," he said silently. "I'm coming back,"

  Back to enjoy and cherish all the beauties of the world he had thought was lost forever. No—not all of them.

  He would never enjoy summer again.

  OUT OF THE CRADLE, ENDLESSLY ORBITING...

  BEFORE WE START, I'd like to point out something that a good many people seem to have overlooked. The twenty-first century does not begin tomorrow; it begins a year later, on January 1, 2001. Even though the calendar reads 2000 from midnight, the old century still has twelve months to run. Every hundred years we astronomers have to explain this all over again, but it makes no difference. The celebrations start just as soon as the two zeros go up. . . .

  So you want to know my most memorable moment in fifty years of space exploration ... I suppose you've already interviewed von Braun? How is he? Good; I've not seen him since that symposium we arranged in Astrograd on his eightieth birthday, the last time he came down from the Moon.

  Yes—I've been present at some of the biggest moments in the history of space flight, right back to the launching of the first satellite. I was only twenty-five then, and a very junior mathematician at Kapustin Yar—not important enough to be in the control center during the countdown. But I heard the take-off: it was the second most awe-inspiring sound I've heard in my entire life. (The first? I'll come to that later.) When we knew we'd hit orbit, one of the senior scientists called for his Zis, and we drove into Stalingrad for a real party. Only the very top people had cars in the Workers' Paradise, you know; we made the hundred-kilometer drive in just about the same time the Sputnik took for one circuit of Earth, and that was pretty good going. Someone calculated that the amount of vodka consumed the next day could have launched the satellite the Americans were building, but I don't think that was quite true.

  Most of the history books say that the Space Age began then, on October 4, 1957; I'm not going to argue with them, but I think the really exciting times came later. For sheer drama you can't beat the U.S. Navy's race to fish Dimitri Kalinin out of the South Atlantic before his capsule sank. Then there was Jerry Wingate's radio commentary, with all the adjectives which no network dared to censor, as he rounded the Moon and became the first man to see its hidden face. And, of course, only five years later, that TV broadcast from the cabin of the Hermann Oberth as she touched down on the plateau in the Bay of Rainbows, where she still stands, an eternal monument to the men buried beside her.

  Those were the great landmarks on the road to space, but you're wrong if you think I'm going to talk about them; for what made the greatest impact on me was something very, very different. I'm not even sure if I can share the experience, and if I succeed you won't be able to make a story out of it. Not a new one, anyway, for the papers were full of it at the time. But most of them missed the point completely; to them it was just good human-interest material, nothing more.

  The time was twenty years after the launching of Sputnik I, and by then, with a good many other people, I was on the Moon . . . and too important, alas, to be a real scientist any more. It had been a dozen years since I'd programmed an electronic computer; now I had the slightly more difficult task of programming human beings, since I was Chief Co-ordinator of Project Ares, the first manned expedition to Mars.

  We were starting from the Moon, of course, because of the low gravity; it's about fifty times easier, in terms of fuel, to take off from there than from the Earth. We'd thought of constructing the ships in a satellite orbit, which would have cut fu
el requirements even further, but when we looked into it, the idea wasn't as good as it seemed. It's not easy to set up factories and machine shops in space; the absence of gravity is a nuisance rather than an advantage when you want things to stay put. By that time, at the end of the seventies, the First Lunar Base was getting well organized, with chemical processing plants and all kinds of small-scale industrial operations to turn out the things the colony needed. So we decided to use the existing facilities rather than set up new ones, at great difficulty and expense, out in space.

  Alpha, Beta, and Gamma, the three ships of the expedition, were being built inside the ramparts of Plato, perhaps the most perfect of all the walled plains on this side of the Moon. It's so large that if you stand in the middle you could never guess that you were inside a crater; the ring of mountains around you is hidden far below the horizon. The pressure domes of the base were about ten kilometers from the launching site, connected to it by one of those overhead cable systems that the tourists love to ride on, but which have ruined so much of the lunar scenery.

  It was a rugged sort of life, in those pioneering days, for we had none of the luxuries everyone now takes for granted. Central Dome, with its parks and lakes, was still a dream on the architects' drawing boards; even if it had existed, we would have been too busy to enjoy it, for Project Ares devoured all our waking moments. It would be Man's first great leap into space; by that time we already looked on the Moon as no more than a suburb of Earth, a steppingstone on the way to places that really mattered. Our beliefs were neatly expressed by that famous remark of Tsiolkovsky's, which I'd hung up for everyone to see as they entered my office:
