The third flag flew over the Cutoff Colony Theory. According to this, an early terrestrial civilization had colonized Minerva, and then declined into a Dark Age during which contact with the colony was lost. The deteriorating conditions of the Ice Age later prompted a recovery on both planets, with the difference that Minerva faced a life-or-death situation and began the struggle to regain the lost knowledge in order that a return to Earth might be made. Earth, however, was going through lean times of its own and, when the advance parties from Minerva eventually made contact, didn’t react favorably to the idea of another planetful of mouths to feed. Diplomacy having failed, the Minervans set up an invasion beachhead on Luna. The Annihilator at Seltar had thus been firing at targets on Earth; the translators had been misled by identical place-names on both planets-like Boston, New York, Cambridge, and a hundred other places in the USA, many of the towns on Minerva had been named after places on Earth when the original colony was first established.
The defenders of these arguments drew heavily from the claims of the Pure Earthists to account for the absence of Lunarian relics on Earth. In addition, they produced further support from the unlikely domain of the study of fossil corals in the Pacific. It had been known for a long time that analysis of the daily growth rings of ancient fossil corals provided a measure of how many days there had been in the year at various times in the past, and from this how fast the forces of tidal friction were slowing down the rotation of the Earth about its axis. These researches showed, for example, that the year of 350 million years ago contained about four hundred days. Ten years previously, work conducted at the Darwin Institute of Oceanography in Australia, using more refined and more accurate techniques, had revealed that the continuity from ancient to modem had not been as smooth as supposed. There was a confused period in the recent past-at about fifty thousand years before-during which the curve was discontinuous, and a comparatively abrupt lengthening in the day had occurred. Furthermore, the rate of deceleration was measurably greater after this discontinuity than it had been before. Nobody knew why this should have happened, but it seemed to indicate a period of violent climatic upheaval, as the corals had taken generations to settle down to a stable growth pattern afterward. The data seemed to indicate that widespread changes had taken place on Earth around this mysterious point in time, probably accompanied by global flooding, and all in all there could be enough behind the story to explain the complete disappearance of any record of the Lunarians’ existence.
The fourth main theory was that of the Returning Exiles, which found these attempts to explain the disappearance of the terrestrial Lunarians artificial and inadequate. The basic tenet of this theory was that there could be only one satisfactory reason for the fact that there were no signs of Lunarians on Earth: There had never been any Lunarians on Earth worth talking about. Thus, they had evolved on Minerva as Danchekker maintained and had evolved an advanced civilization, unlike their contemporary brothers on Earth, who remained backward. Eventually, compelled by the Ice Age threat of extinction, the two superpowers of Cerios and Lambia had emerged and begun the race toward the Sun in the way described by Linguistics. Where Linguistics had gone wrong, however, was that by the time of Charlie’s narrative, these events were already historical; the goal was already achieved. The Lambians had drawn ahead by a small margin and had already commenced building settlements on Earth, several of them named after their own towns on Minerva. The Cerians followed hard on their heels and established a fire base on Luna, the objective of course being to knock out the Lambian outposts on Earth before moving in themselves.
This theory did not explain the flight time of Charlie’s ship, but its supporters attributed the difficulty to unknown differences between Minervan and local (Lunar) dating systems. On the other hand, it required only a few pilot Lambian bases to have been set up on Earth by the time of the war; thus, whatever remained of these after the Cerian assault, could credibly have vanished in fifty thousand years.
And as the battle lines were drawn up and the first ranging shots started whistling up and down the corridors of Navcomms, in no-man’s-land sat Hunt. Somehow, he was convinced, everybody was right. He knew the competence of the people around him and had no doubt in their ability to get their figures right. If, after weeks or months of patient effort, one of them pronounced that x was 2, then he was quite prepared to believe that, in all probability, it would turn out to be. Therefore, the paradox had to be an illusion. To try to argue which side was right and which was wrong was missing the whole point. Somewhere in the maze, probably so fundamental that nobody had even thought to question it, there had to be a fallacy-some wrong assumption that seemed so obvious they didn’t even realize they were making it. If they could just get back to fundamentals and identify that single fallacy, the paradox would vanish and everything that was being argued would slide smoothly into a consistent, unified whole.
Chapter Eighteen
"You want me to go to Jupiter?" Hunt repeated slowly, making sure he had heard correctly.
Caldwell stared back over his desk impassively. "The Jupiter Five Mission will depart from Luna in six weeks time," he stated. "Danchekker has gone about as far as he can go with Charlie. What details are left to be found out can be taken care of by his staff at Westwood. He’s got better things he’d like to be doing on Ganymede. There’s a whole collection of alien skeletons there, plus a shipload of zoology from way back that nobody’s ever seen the like of before. It’s got him excited. He wants to get his hands on them. Jupiter Five is going right there, so he’s getting together a biological team to go with it."
Hunt already knew all this. Nevertheless, he went through the motions of digesting the information and checking through it for any point he might have missed. After an appropriate pause he replied:
"That’s fine-I can see his angle. But what does it have to do with me?"
Caldwell frowned and drummed his fingers, as if he had been expecting this question to come, while hoping it wouldn’t.
"Consider this an extension of your assignment," he said at last. "From all the arguing that’s going on around this place, nobody seems to be able to agree just how the Ganymeans fit into the Charlie business. Maybe they’re a big part of the answer, maybe they’re not. Nobody knows for sure."
"True." Hunt nodded.
Caldwell took this as all the confirmation he needed. "Okay," he said with a gesture of finality. "You’ve done a good job so far on the Charlie side of the picture; maybe it’s time to balance things up a bit and give you a crack at the other side, too. Well"-he shrugged-"the information’s not here-it’s on Ganymede. In six weeks time, J Five shoves off for Ganymede. It makes sense to me that you go with it."
Hunt’s brow remained creased in an expression that indicated he still didn’t quite see everything. He posed the obvious question. "What about the job here?"
"What about it? Basically you correlate information that comes from different places. The information will still keep coming from the places whether you’re in Houston or on board Jupiter Five. Your assistant is capable of stepping in and keeping the routine background research and cross-checking running smoothly in Group L. There’s no reason why you can’t continue to be kept updated on what’s going on if you’re out there. Anyhow, a change of scene never did anybody any harm. You’ve been on this job a year and a half now."
"But we’re talking about a break of years, maybe."
"Not necessarily. Jupiter Five is a later design than J Four; it will make Ganymede in under six months. Also, a number of ships are being ferried out with the Jupiter Five Mission to start building up a fleet that will be based out there. Once a reserve’s been established, there will be regular two-way traffic with Earth. In other words, once you’ve had enough of the place we’ll have no problem getting you back."
Hunt reflected that nothing ever seemed to stay normal for very long when Caldwell was around. He felt no inclination to argue with this new directive. On the contrary, th
e prospect excited him. But there was something that didn’t quite add up in the reasons Caldwell was giving. Hunt had the same feeling he had experienced on previous occasions that there was an ulterior motive lurking beneath the surface somewhere. Still, that didn’t really matter. Caldwell seemed to have made up his mind, and Hunt knew from experience that when Caldwell made up his mind that something would be so, then by some uncanny power of preordination, so it would inevitably turn out to be.
Caldwell waited for possible objections. Seeing that none were forthcoming, he concluded: "When you joined us, I told you your place in UNSA was out front. That statement implied a promise. I always keep promises."
For the next two weeks Hunt worked frantically, reorganizing the operation of Group L and making his own personal preparations for a prolonged absence from Earth. After that, he was sent to Galveston for two weeks.
By the third decade of the twenty-first century, commercial flight reservations to Luna could be made through any reputable travel agent, for seats either on regular UNSA ships or on chartered ships crewed by UNSA officers. The standards of comfort provided on passenger ifights were high, and accommodation at the larger Lunar bases was secure, enabling Lunar travel to become a routine chore in the lives of many businessmen and a memorable event for more than a few casual visitors, none of whom needed any specialized knowledge or training. Indeed, one enterprising consortium, comprised of a hotel chain, an international airline, a travel-tour operator, and an engineering corporation, had commenced the construction of a Lunar holiday resort, which was already fully booked for the opening season.
Places like Jupiter, however, were not yet open to the public. Persons detailed for assignments with the UNSA deep-space missions needed to know what they were doing and how to act in emergency situations. The ice sheets of Ganymede and the cauldron of Venus were no places for tourists.
At Galveston, Hunt learned about UNSA spacesuits and the standard items of ancillary equipment; he was taught the use of communication equipment, survival kits, emergency life support systems, and repair kits; he practiced test routines, radiolocation procedures, and equipment-fault diagnostic techniques. "Your life could depend on this little box," one instructor told the group. "You could wind up in a situation where it fails and the only person inside a hundred miles to fix it is you." Doctors lectured on the rudiments of space medicine and recommended methods of dealing with oxygen starvation, decompression, heat stroke, and hypothermia. Physiologists described the effects on bone calcium of long periods of reduced body weight, and showed how a correct balance could be maintained by a specially selected diet and drugs. UNSA officers gave useful hints that covered the whole gamut of staying alive and sane in alien environments, from navigating afoot on a hostile surface using satellite beacons as reference points, to the art of washing one’s face in zero gravity.
And so, just over four weeks after his directive from Caldwell, Hunt found himself fifty feet below ground level at pad twelve of number-two terminal complex twenty miles outside Houston, walking along one of the access ramps that connected the wall of the silo to the gleaming hull of the Vega. An hour later, the hydraulic ramps beneath the platform supporting the tail thrust the ship slowly upward and out, to stand clear on the roof of the structure. Within minutes the Vega was streaking into the darkening void above. It docked thirty minutes later, two and a half seconds behind schedule, with the half-mile-diameter transfer satellite Kepler.
On Kepler the passengers traveling on to Luna-including Hunt, three propulsion-systems experts keen to examine the suspected Ganymean gravity drives, four communications specialists, two structural engineers, and Danchekker’s team, all destined to join Jupiter Five-transferred to the ugly and ungainly Capella class moonship that would carry them for the remainder of the journey from Earth orbit to the Lunar surface. The voyage lasted thirty hours and was uneventful. After they had been in Lunar orbit for twenty minutes, the announcement came over the loudspeaker that the craft had been cleared for descent.
Shortly afterward, the unending procession of plains, mountains, crags, and hills that had been marching across the cabin display screen slowed to a halt and the view started growing perceptibly larger. Hunt recognized the twin ring-walled plains of Ptolemy and Albategnius, with its central conical mountain and Crater Klein interrupting its encircling wall, before the ship swung northward and these details were lost off the top of the steadily enlarging image. The picture stabilized, now centered upon the broken and crumbling mountain wall that separated Ptolemy from the southern edge of the Plain of Hipparchus. What had previously looked like smooth terrain resolved itself into a jumble of rugged cliffs and valleys, and in the center, glints of sunlight began to appear, reflected from the metal structures of the vast base below.
As the outlines of the surface installations materialized out of the gray background and expanded to fill the screen, a yellow glow in the center grew, gradually transforming into the gaping entrance to one of the underground moonship berths. There was a brief impression of tiers of access levels stretching down out of sight and huge service gantries swung back to admit the ship. Rows of brilliant arc lights flooded the scene before the exhaust from the braking motors blotted out the view. A mild jolt signaled that the landing legs had made contact with Lunar rock, and silence fell abruptly inside the ship as the engines were cut. Above the squat nose of the moonship, massive steel shutters rolled together to seal out the stars. As the berth filled with air, a new world of sound impinged on the ears of the ship’s occupants. Shortly afterward, the access ramps slid smoothly from the walls to connect the ship to the reception bays.
Thirty minutes after clearing arrival formalities, Hunt emerged from an elevator high atop one of the viewing domes that dominated the surface of Ptolemy Main Base. For a long time he gazed soberly at the harsh desolation in which man had carved this oasis of life. The streaky blue and white disk of Earth, hanging motionless above the horizon, suddenly brought home to him the remoteness of places like Houston, Reading, Cambridge, and the meaning of everything familiar, which until so recently he had taken for granted. In his wanderings he had never come to regard any particular place as home; unconsciously he had always accepted any part of the world to be as much home as any other. Now, all at once, he realized that he was away from home for the first time in his life.
As Hunt turned to take in more of the scene below, he saw that he was not alone. On the far side of the dome a lean, balding figure stood staring silently out over the wilderness, absorbed in thoughts of its own. Hunt hesitated for a long time. At last he moved slowly across to stand beside the figure. All around them the mile-wide clutter of silver-gray metallic geometry that made up the base sprawled amid a confusion of pipes, girders, pylons, and antennae. On towers above, the radars swept the skyline in endless circles, while the tall, praying-mantis-like laser transceivers stared unblinkingly at the heavens, carrying the ceaseless dialogues between the base computers and unseen communications satellites fifty miles up. In the distance beyond the base, the rugged bastions of Ptolemy’s mountain wall towered above the plain. From the blackness above them, a surface transporter was sliding toward the base on its landing approach.
Eventually Hunt said: "To think-a generation ago, all this was just desert." It was more a thought voiced than a statement.
Danchekker did not answer for a long time. When he did, he kept his eyes fixed outside.
"But man dared to dream…" he murmured slowly. After a pause he added, "And what man dares to dream today, tomorrow he makes come true."
Another long silence followed. Hunt took a cigarette from his case and lit it. "You know," he said at last, blowing a stream of smoke slowly toward the glass wall of the dome, "it’s going to be a long voyage to Jupiter. We could get a drink down below-one for the road, as it were."
Danchekker seemed to turn the suggestion over in his mind for a while. At length he shifted his gaze back within the confines of the dome and turned to face Hunt
directly.
"I think not, Dr. Hunt," he said quietly.
Hunt sighed and made as if to turn.
"However,…" The tone of Danchekker’s voice checked him before he moved. He looked up. "If your metabolism is capable of withstanding the unaccustomed shock of nonalcoholic beverages, a strong coffee might, ah, perhaps be extremely welcome."
It was a joke. Danchekker had actually cracked a joke!
"I’ll try anything once," Hunt said as they began walking toward the door of the elevator.
Chapter Nineteen
Embarkation on the orbiting Jupiter Five command ship was not scheduled to take place until a few days later. Danchekker would be busy making final arrangements for his team and their equipment to be ferried up from the Lunar surface. Hunt, not being involved in these undertakings, prepared an itinerary of places to visit during the free time he had available.
The first thing he did was fly to Tycho by surface transporter to observe the excavations still going on around the areas of some of the Lunarian finds, and to meet at last many of the people who up until then had existed only as faces on display screens. He also went to see the deep mining and boring operations in progress not far from Tycho, where engineers were attempting to penetrate to the core regions of the Moon. They believed that concentrations of rich metal-bearing ores might be found there. If this turned out to be so, within decades the Moon could become an enormous spaceship factory, where parts prefabricated in processing and forming plants on the surface would be ferried up for final assembly in Lunar orbit. The economic advantages of constructing deep-space craft here and from Lunar materials, without having to lift everything up out of Earth’s gravity pit to start with, promised to be enormous.
