  The party spent some hours in the recently erected laboratory dome, inspecting items brought up from below the ice, including several Ganymean skeletons and a score of terrestrial animals. To Danchekker's disappointment, his particular favorite—the man-ape anthropoid he had shown to Hunt and Caldwell many months before on a viewscreen in Houston—was not among them. "Cyril" had been transferred to the laboratories of the Jupiter Four command ship for detailed examination. The name, graciously bestowed by the UNSA biologists, was in honor of the mission's chief scientist.

  After lunch in the base canteen, they walked into the dome that covered one of the shaftheads. Fifteen minutes later they were standing deep below the surface of the ice field, gazing in awe at the ship itself.

  It lay, fully uncovered, in the vast white floodlighted cavern, its underside still supported in its mold of ice. The hull cut a clean swath through the forest of massive steel jacks and ice pillars that carried the weight of the roof. Beneath the framework of ramps and scaffolding that clung to its side, whole sections of the hull had been removed to reveal the compartments inside. The floor all around was littered with pieces of machinery lifted out by overhead cranes. The scene reminded Hunt of the time he and Borlan had visited Boeing's huge plant near Seattle where they assembled the 1017 skyliners—but everything here was on a far vaster scale.

  They toured the network of catwalks and ladders that had been laid throughout the ship, from the command deck with its fifteen-foot-wide display screen, through the control rooms, living quarters, and hospital, to the cargo holds and the tiers of cages that had contained the animals. The primary energy-converter and generator section was as imposing and as complex as the inside of a thermonuclear power station. Beyond it, they passed through a bulkhead and found themselves dwarfed beneath the curves of the exposed portions of a pair of enormous toroids. The engineer leading them pointed up at the immense, sweeping surfaces of metal.

  "The walls of those outer casings are sixteen feet thick," he informed them. "They're made from an alloy that would cut tungsten-carbide steel like cream cheese. The mass concentration inside them is phenomenal. We think they provided closed paths in which masses of highly concentrated matter were constrained in circulating or oscillating resonance, interacting with strong fields. It's possible that the high rates of change of gravity potential that this produced were somehow harnessed to induce a controlled distortion in the space around the ship. In other words, it moved by continuously falling into a hole that it created in front of itself—kind of like a four-dimensional tank track."

  "You mean it trapped itself inside a space-time bubble, which propagated somehow through normal space?" somebody offered.

  "Yes, if you like," the engineer affirmed. "I guess a bubble is as good an analogy as any. The interesting point is, if it did work that way, every particle of the ship and everything inside it would be subjected to exactly the same acceleration. Therefore there would be no G effect. You could stop the ship dead from, say, a million miles an hour to zero in a millisecond, and nobody inside would even know the difference."

  "How about top speed?" someone else asked. "Would there have been a relativistic limit?"

  "We don't know. The theory boys up in Jupiter Four have been losing a lot of sleep over that. Conventional mechanics wouldn't apply to any movement of the ship itself, since it wouldn't be actually moving in the local space inside the bubble. The question of how the bubble propagates through normal space is a different ball game altogether. A whole new theory of fields has to be worked out. Maybe completely new laws of physics apply—as I said before, we just don't know. But one thing seems clear: Those photon-drive starships they're designing in California might turn out to be obsolete before they're even built. If we can figure out enough about how this ship worked, the knowledge could put us forward a hundred years."

  By the end of the day Hunt's mind was in a whirl. New information was coming in faster than he could digest it. The questions in his head were multiplying at a rate a thousand times faster than they could ever be answered. The riddle of the Ganymean spaceship grew more intriguing with every new revelation, but at the back of it there was still the Lunarian problem unresolved. He needed time to stand back and think, to put his mental house in order and sort the jumble into related thoughts that would slot into labeled boxes in his mind. Then he would be able to see better which question depended on what, and which needed to be tackled first. But the jumble was piling up faster than he could pick up the pieces.

  The banter and laughter in the mess after the evening meal soon became intolerable. Alone in his room, he found the walls claustrophobic. For a while he walked the deserted corridors between the domes and buildings. They were oppressive; he had lived in metal cans for too long. Eventually he found himself in the control tower dome, staring out into the incandescent gray wall that was produced by the floodlights around the base soaking through the methane-ammonia fog of the Ganymedean night. After a while even the presence of the duty controller, his face etched out against the darkness by the glow from his console, became an intrusion. Hunt stopped by the console on his way to the stairwell.

  "Check me out for surface access."

  The duty controller looked across at him. "You're going outside?"

  "I need some air."

  The controller brought one of his screens to life. "You are who, please?"

  "Hunt. Dr. V. Hunt."

  "ID?"

  "730289 C/EX4."

  The controller logged the details, then checked the time and keyed it in.

  "Report in by radio in one hour's time if you're not back. Keep a receiver channel open permanently on 24.328 megahertz."

  "Will do," Hunt acknowledged. "Good night."

  "Night."

  The controller watched Hunt disappear toward the floor below, shrugged to himself, and automatically scanned the displays in front of him. It was going to be a quiet night.

  In the surface access anteroom on the ground level, Hunt selected a suit from the row of lockers along the right-hand wall. A few minutes later, suited up and with his helmet secured, he walked to the airlock, keyed his name and ID code into the terminal by the gate, and waited a couple of seconds for the inner door to slide open.

  He emerged into the swirling silver mist and turned right to follow the line of the looming black metal cliff of the control building. The crunch of his boots in the powder ice sounded faint and far away, through the thin vapors. Where the wall ended he continued walking slowly in a straight line, out into the open area and toward the edge of the base. Phantom shapes of steel emerged and disappeared in the silent shadows around him. The gloom ahead grew darker as inlands of diffuse light passed by on either side. The ice began sloping upward. Irregular patches of naked, upthrusting rock became more frequent. He walked on as if in a trance.

  Pictures from the past rolled by before his mind's eye: a boy, reading books, shut away in the upstairs bedroom of a London slum . . . a youth, pedaling a bicycle each morning through the narrow streets of Cambridge. The people he had been were no more real than the people he would become. All through his life he had been moving on, never standing still, always in the process of changing from something he had been to something he would be. And beyond every new world, another beckoned. And always the faces around him were unfamiliar ones—they drifted into his life like the transient shadows of the rocks that now moved toward him from the mists ahead. Like the rocks, for a while the people seemed to exist and take on form and substance, before slipping by to dissolve into the shrouds of the past behind him, as if they had never been. Forsyth-Scott, Felix Borlan, and Rob Gray had already ceased to exist. Would Caldwell, Danchekker, and the rest soon fade away to join them? And what new figures would materialize out of the unknown worlds lying hidden behind the veils of time ahead?

  He realized with some surprise that the mists around him were getting brighter again; also, he could suddenly see farther. He was climbing upward
across an immense ice field, now smooth and devoid of rocks. The light was an eerie glow, permeating evenly through mists on every side as if the fog itself were luminous. He climbed higher. With every step the horizon of his vision broadened further, and the luminosity drained from the surrounding mist to concentrate itself in a single patch that second by second grew brighter above his head. And then he was looking out over the top of the fog bank. It was just a pocket, trapped in the depression of the vast basin in which the base had been built; it had no doubt been sited there to shorten the length of the shaft needed to reach the Ganymean ship. The slope above him finished in a long, rounded ridge not fifty feet beyond where he stood. He changed direction slightly to take the steeper incline that led directly to the summit of the ridge. The last tenuous wisps of whiteness fell away.

  At the top, the night was clear as crystal. He was standing on a beach of ice that shelved down from his feet into a lake of cotton wool. On the opposite shore of the lake rose the summits of the rock buttresses and ice cliffs that stood beyond the base. For miles around, ghostly white bergs of Ganymedean ice floated on an ocean of cloud, shining against the blackness of the night.

  But there was no Sun.

  He raised his eyes, and gasped involuntarily. Above him, five times larger than the Moon seen from Earth, was the full disk of Jupiter. No photograph he had ever seen, or any image reproduced on a display screen, could compare with the grandeur of that sight. It filled the sky with its radiance. All the colors of the rainbow were woven into its iridescent bands of light, stacked layer upon layer outward from its equator. They faded as they approached its edge and merged into a hazy circle of pink that encircled the planet. The pink turned to violet and finally to purple, ending in a clear, sharp outline that traced an enormous circle against the sky. Immutable, immovable, eternal . . . mightiest of the gods—and tiny, puny, ephemeral man had crawled on a pilgrimage of five hundred million miles to pay homage.

  Maybe only seconds passed, maybe hours. Hunt could not tell. For a fraction of eternity he stood unmoving, a speck lost among the silent towers of rock and ice. Charlie too had stood upon the surface of a barren waste and gazed up at a world wreathed in light and color—but the colors had been those of death.

  At that moment, the scenes that Charlie had seen came to Hunt more vividly than at any time before. He saw cities consumed by fireballs ten miles high; he saw gaping chasms, seared and blackened ash that had once held oceans, and lakes of fire where mountains had stood. He saw continents buckle and break asunder, and drown beneath a fury of white heat that came exploding outward from below. As clearly as if it were really happening, he saw the huge globe above him swelling and bursting, grotesque with the deceptive slowness of mighty events seen from great distances. Day by day it would rush outward into space, consuming its moons one after the other in an insatiable orgy of gluttony until its force was spent. And then . . .

  Hunt snapped back to reality with a jolt.

  Suddenly the answer he had been seeking was there. It had come out of nowhere. He tried to trace its root by backtracking through his thoughts—but there was nothing. The pathways up from the deeper levels of his mind had opened for a second, but now were closed. The illusion was exposed. The paradox had gone. Of course nobody had seen it before. Who would think to question a truth that was self-evident, and older than the human race itself?

  "Pithead Control calling Dr. V. Hunt. Dr. Hunt, come in, please." The sudden voice in his helmet startled him. He pressed a button in the control panel on his chest.

  "Hunt answering," he acknowledged. "I hear you."

  "Routine check. You're five minutes overdue to report. Is everything okay?"

  "Sorry, didn't notice the time. Yes, everything's okay . . . very okay. I'm coming back now."

  "Thank you." The voice cut off with a click.

  Had he been gone that long? He realized that he was cold. The icy fingers of the Ganymedean night were beginning to feel their way inside his suit. He wound his heating control up a turn and flexed his arms. Before he turned, he looked up once more for a final glimpse of the giant planet. For some strange reason it seemed to be smiling.

  "Thanks, pal," he murmured with a wink. "Maybe I'll be able to do something for you someday."

  With that he began moving down from the ridge, and rapidly faded into the sea of cloud.

  Chapter Twenty-Three

  A group of about thirty people, mainly scientists, engineers, and UNSA executives, filed into the conference theater in the Navcomms Headquarters building. The room was arranged in ascending tiers of seats that faced a large blank screen at the far end from the double doors. Caldwell was standing on a raised platform in front of the screen, watching as the various groups and individuals found seats. Soon everybody was settled and an usher at the rear signaled that the corridor outside was empty. Caldwell nodded in acknowledgment, raised his hand for silence, and stepped a pace forward to the microphone in front of him.

  "Your attention, please, ladies and gentlemen . . . Could we have quiet, please . . ." The baritone voice boomed out of the loudspeakers around the walls. The murmurs subsided.

  "Thank you all for coming on such short notice," he resumed. "All of you have been engaged for some time now in some aspect or other of the Lunarian problem. Ever since this thing first started, there have been more than a few arguments and differences of opinions, as you all know. Taking all things into consideration, however, we haven't done too badly. We started out with a body and a few scraps of paper, and from them we reconstructed a whole world. But there are still some fundamental questions that have remained unanswered right up to this day. I'm sure there's no need for me to recap them for the benefit of anyone here." He paused. "At last, it appears, we may have answers to those questions. The new developments that cause me to say this are so unexpected that I feel it appropriate to call you all together to let you see for yourselves what I saw for the first time only a few hours ago." He waited again and allowed the mood of the gathering to move from one suited to preliminary remarks to something more in tune with the serious business about to begin.

  "As you all know, a group of scientists left us many months ago with the Jupiter Five Mission to investigate the discoveries on Ganymede. Among that group was Vic Hunt. This morning we received his latest report on what's going on. We are about to replay the recording for you now. I think you will find it interesting."

  Caldwell glanced toward the projection window at the back of the room and raised his hand. The lights began to fade. He stepped down from the platform and took his seat in the front row. Darkness reigned briefly. Then the screen illuminated to show a file header and reference frame in standard UNSA format. The header persisted for a few seconds, then disappeared to be replaced by the image of Hunt, facing the camera across a desktop.

  "Navcomms Special Investigation to Ganymede, V. Hunt reporting, 20 November 2029, Earth Standard Time," he announced. "Subject of transmission: A Hypothesis Concerning Lunarian Origins. What follows is not claimed to be rigorously proven theory at this stage. The object is to present an account of a possible sequence of events which, for the first time, explains adequately the origins of the Lunarians, and is also consistent with all the facts currently in our possession." Hunt paused to consult some notes on the desk before him. In the conference theater the silence was absolute.

  Hunt looked back up and out of the screen. "Up until now I've tended not to accent any particular one of the ideas in circulation in preference to the rest, primarily because I haven't been sufficiently convinced that any of them, as stated, accounted adequately for everything that we had reason to believe was true. That situation has changed. I have now come to believe that one explanation exists which is capable of supporting all the evidence. That explanation is as follows:

  "The Solar System was formed originally with nine planets, which included Minerva and extended out as far as Neptune. Akin to the inner planets and located beyond Mars, Minerva resembled Earth in
many ways. It was similar in size and density and was composed of a mix of similar elements. It cooled and developed an atmosphere, a hydrosphere, and a surface composition." Hunt paused for a second. "This has been one source of difficulty—reconciling surface conditions at this distance from the Sun with the existence of life as we know it. For proof that these factors can indeed be reconciled, refer to Professor Fuller's work at London University during the last few months." A caption appeared on the lower portion of the screen, giving details of the titles and access codes of Fuller's papers on the subject.

  "Briefly, Fuller has produced a model of the equilibrium states of various atmospheric gases and volcanically introduced water vapor, that is consistent with known data. To sustain the levels of free atmospheric carbon dioxide and water vapor, and the existence of large amounts of water in a liquid state, the model requires a very high level of volcanic activity on the planet, at least in its earlier history. That this requirement was evidently met could suggest that relative to its size, the crust of Minerva was exceptionally thin, and the structure of this crust unstable. This is significant, as becomes clear later. Fuller's model also ties in with the latest information from the Asteroid surveys. The thin crust could be the result of relatively rapid surface cooling caused by the vast distance from the Sun, but with the internal molten condition being prolonged by heat sources below the surface. The Asteroid missions report many samples being tested that are rich in radioactive heat-producing substances.
