2010: Odyssey Two o-2

by Arthur Charles Clarke


  So it went on, case after case. Very few of the contactees were actually lying or insane; most of them sincerely believed their own stories, and retained that belief even under hypnosis. And some were just victims of practical jokes or improbable accidents – like the unlucky amateur archaeologists who found the props that a celebrated science-fiction moviemaker had abandoned in the Tunisian desert almost four decades earlier.

  Yet only at the beginning – and at the very end – was any human being genuinely aware of his presence; and that was because he so desired it.

  The world was his to explore and examine as he pleased, without restraint or hindrance. No walls could keep him out, no secrets could be hidden from the senses he possessed. At first he believed that he was merely fulfilling old ambitions, by visiting the places he had never seen in that earlier existence. Not until much later did he realize that his lightning-like sallies across the face of the globe had a deeper purpose.

  In some subtle way, he was being used as a probe, sampling every aspect of human affairs. The control was so tenuous that he was barely conscious of it; he was rather like a hunting dog on a leash, allowed to make excursions of his own, yet nevertheless compelled to obey the overriding wishes of his master.

  The pyramids, the Grand Canyon, the moon-washed snows of Everest – these were choices of his own. So were some art galleries and concert halls; though he would certainly, on his own initiative, never have endured the whole of the Ring.

  Nor would he have visited so many factories, prisons, hospitals, a nasty little war in Asia, a racecourse, a complicated orgy in Beverly Hills, the Oval Room of the White House, the Kremlin archives, the Vatican Library, the sacred Black Stone of the Kaabah at Mecca.

  There were also experiences of which he had no clear memory, as if they had been censored – or he was being protected from them by some guardian angel. For example -What was he doing at the Leakey Memorial Museum, in Olduvai Gorge? He had no greater interest in the origin of Man than any other intelligent member of the species H. sapiens, and fossils meant nothing to him. Yet the famous skulls, guarded like crown jewels in their display cases, aroused strange echoes in his memory, and an excitement for which he was unable to account. There was a feeling of déja vu stronger than any he had ever known; the place should be familiar – but something was wrong. It was like a house to which one returns after many years, to find that all the furniture has been changed, the walls moved, and even the stairways rebuilt.

  It was bleak, hostile terrain, dry and parched. Where were the lush plains and the myriad fleet-footed herbivores that had roamed across them, three million years ago?

  Three million years. How had he known that?

  No answer came from the echoing silence into which he had thrown the question. But then he saw, once more looming before him, a familiar black rectangular shape. He approached, and a shadowy image appeared in its depths, like a reflection in a pool of ink.

  The sad and puzzled eyes that stared back from beneath that hairy, receding forehead looked beyond him into a future they could never see. For he was that future, a hundred thousand generations further down the stream of time.

  History had begun there; that at least he now understood. But how – and above all, why – were secrets still withheld from him?

  But there was one last duty, and that was hardest of all. He was still sufficiently human to put it off until the very end.

  Now what's she up to? the duty nurse asked herself, zooming the TV monitor onto the old lady. She's tried lots of tricks, but this is the first time I've seen her talking to her hearing aid, for goodness sake. I wonder what she's saying?

  The microphone was not sensitive enough to pick up the words, but that scarcely seemed to matter. Jessie Bowman had seldom looked so peaceful and content. Though her eyes were closed, her entire face was wreathed in an almost angelic smile while her lips continued to form whispered words.

  And then the watcher saw something that she tried hard to forget because to report it would instantly disqualify her in the nursing profession. Slowly and jerkily, the comb lying on the bedside table raised itself in the air as if lifted by clumsy, invisible fingers.

  On the first attempt, it missed; then, with obvious difficulty, it began to part the long silver strands, pausing sometimes to disentangle a knot.

  Jessie Bowman was not speaking now, but she continued to smile. The comb was moving with more assurance, and no longer in abrupt, uncertain jerks.

  How long it lasted the nurse could never be certain. Not until the comb was gently replaced on the table did she recover from her paralysis.

  Ten-year-old Dave Bowman had finished the chore which he always hated but which his mother loved. And a David Bowman who was now ageless had gained his first control of obdurate matter.

  Jessie Bowman was still smiling when the nurse finally came to investigate. She had been too scared to hurry; but it would have made no difference anyway.

  35 – Rehabilitation

  The uproar of Earth was comfortably muted, across the millions of kilometres of space. Leonov's crew watched, with fascination yet with a certain detachment, the debates in the United Nations, the interviews with distinguished scientists', the theorizing of the news commentators, the matter-of-fact yet wildly conflicting accounts of the UFO contactees. They could contribute nothing to the brouhaha, for they had witnessed no further manifestations of any kind. Zagadka, alias Big Brother, remained as blankly indifferent to their presence as ever. And that was indeed an ironic situation; they had come all the way from Earth to solve a mystery – and it looked as if the answer might be right back at their starting point.

  For the first time, they felt grateful for the slow velocity of light, and the two-hour delay that made live interviews impossible on the Earth-Jupiter circuit. Even so, Floyd was badgered by so many media requests that he finally went on strike. Nothing more remained to be said, and he had said it at least a dozen times.

  Besides, there was still much work to be done. Leonov had to be prepared for the long journey home, so that it would be ready to depart immediately when the launch window opened. The timing was not at all critical; even if they missed by a month, that would merely prolong the trip. Chandra, Curnow, and Floyd would not even notice as they slept their way toward the Sun; but the rest of the crew was grimly determined to leave just as soon as the laws of celestial mechanics permitted.

  Discovery still posed many problems. The ship had barely sufficient propellant for the return to Earth, even if it left much later than Leonov and flew a minimum-energy orbit – which would take almost three years. And this would be possible only if Hal could be reliably programmed to carry out the mission with no human intervention except long-range monitoring. Without his cooperation, Discovery would have to be abandoned once again.

  It had been fascinating – indeed, deeply moving – to watch the steady regrowth of Hal's personality, from brain-damaged child to puzzled adolescent and at length to slightly condescending adult. Although he knew that such anthropomorphic labels were highly misleading, Floyd found it quite impossible to avoid them.

  And there were times when he felt that the whole situation had a haunting familiarity. How often he had seen videodramas in which disturbed youngsters were straightened out by all-wise descendants of the legendary Sigmund Freud! Essentially the same story was being played out in the shadow of Jupiter.

  The electronic psychoanalysis had proceeded at a speed totally beyond human comprehension as repair and diagnostic programs flashed through Hal's circuits at billions of bits a second, pinpointing possible malfunctions and correcting them. Though most of these programs had been tested in advance on Hal's twin, SAL 9000, the impossibility of a real-time dialogue between the two computers was a serious handicap. Sometimes hours were wasted when it proved necessary to check back with Earth at a critical point in the therapy.

  For despite all Chandra's work, the computer's rehabilitation was still far from complete. Hal exhibited num
erous idiosyncrasies and nervous tics, sometimes even ignoring spoken words – though he would always acknowledge keyboard inputs from anyone. In the reverse direction, his outputs were even more eccentric.

  There were times when he would give verbal replies, but would not display them visually. At other times he would do both – but refused to print hard copy. He would give no excuses or explanations – not even the stubbornly impenetrable 'I prefer not to' of Melville's autistic scrivener, Bartelby.

  However, he was not actively disobedient so much as reluctant, and only where certain tasks were concerned. It was always possible to win his cooperation eventually – 'to talk him out of his sulk', as Curnow put it neatly.

  It was not surprising that Dr Chandra was beginning to show the strain. On one celebrated occasion when Max Brailovsky innocently revived an old canard, he almost lost his temper.

  'Is it true, Dr Chandra, that you chose the name Hal to be one step ahead of IBM?'

  'Utter nonsense! Half of us come from IBM and we've been trying to stamp out that story for years. I thought that by now every intelligent person knew that H-A-L is derived from Heuristic ALgorithmic.'

  Afterward, Max swore that he could distinctly hear the capital letters.

  In Floyd's private opinion, the odds were at least fifty to one against flying Discovery safely back to Earth. And then Chandra came to him with an extraordinary proposal.

  'Dr Floyd, can I have a word with you?'

  After all the weeks and shared experiences, Chandra was still as formal as ever – not only to Floyd, but to all the crew. He would not even address the ship's baby, Zenia, without the prefix 'ma'am'.

  'Of course, Chandra. What is it?'

  'I've virtually completed the programming for the six most probable variations on the Hohmann return orbit. Five have now been run on a simulation, without any problems.'

  'Excellent. I'm sure that no one else on Earth – in the Solar System – could have done it.'

  'Thank you. However, you know as well as I do that it's impossible to program for every eventuality. Hal may – will – function perfectly, and will be able to handle any reasonable emergency. But all sorts of trivial accidents – minor equipment failures that could be fixed with a screwdriver, broken wires, stuck switches – could leave him helpless and abort the whole mission.'

  'You're absolutely right, of course, and it's been worrying me. But what can we do about it?'

  'It's really quite simple. I'd like to stay with Discovery.'

  Floyd's immediate reaction was that Chandra had gone crazy. On second thoughts, perhaps he was only half crazy. It might indeed make all the difference between success and failure to have a human being – that superb all-purpose trouble-shooting and repair device – aboard Discovery for the long voyage back to Earth. But the objections were completely overwhelming.

  'It's an interesting idea,' Floyd answered with extreme caution, 'and I certainly appreciate your enthusiasm. But have you thought of all the problems?' That was a silly thing to say; Chandra would have all the answers already filed away for immediate retrieval.

  'You'll be on your own for over three years! Suppose you had an accident or a medical emergency?'

  'That's a risk I'm prepared to take.'

  'And what about food, water? Leonov doesn't have enough to spare.'

  'I've checked Discovery's recycling system; it can be made operational again without too much difficulty. Besides, we Indians can manage on very little.'

  It was unusual for Chandra to refer to his origins, or indeed to make any personal statements; his 'true confession' was the only example Floyd could remember. But he did not doubt the claim; Curnow had once remarked that Dr Chandra had the sort of physique that could only be achieved by centuries of starvation. Although it sounded like one of the engineer's unkinder wisecracks, it had been made entirely without malice – indeed, with sympathy; though not, of course, in Chandra's hearing.

  'Well, we still have several weeks to decide. I'll think it over and talk to Washington.'

  'Thank you; do you mind if I start making the arrangements?'

  'Er – not at all, as long as they don't interfere with the existing plans. Remember – Mission Control will have to make the final decision.'

  And I know exactly what Mission Control will say. It was madness to expect a man to survive in space for three, years, alone.

  But, of course, Chandra had always been alone.

  36 – Fire in the Deep

  Earth was already far behind, and the awesome wonders of the Jovian system were expanding swiftly before him, when he had his revelation.

  How could he have been so blind – so stupid! It was as if he had been walking in his sleep; now he was starting to awaken.

  Who are you? he cried. What do you want? Why have you done this to me?

  There was no answer, yet he was certain that he had been heard. He sensed a... presence, even as a man can tell, though his eyes are tightly shut, that he is in a closed room and not some empty, open space. Around him there was the faint echo of a vast mentality, an implacable will.

  He called again into the reverberant silence, and again there was no direct reply – only that sense of watchful companionship. Very well; he would find the answers for himself.

  Some were obvious; whoever or whatever they were, they were interested in Mankind. They had tapped and stored his memories, for their own inscrutable purposes. And now they had done the same with his deepest emotions, sometimes with his cooperation, sometimes without.

  He did not resent that; indeed, the very processing he had experienced made such childish reactions impossible. He was beyond love and hate and desire and fear – but he had not forgotten them, and could still understand how they ruled the world of which he had once been part. Was that the purpose of the exercise? If so, for what ultimate goal?

  He had become a player in a game of gods, and must learn the rules as he went along.

  The jagged rocks of the four tiny outer moons, Sinope, Pasiphae, Carme, and Ananke, flickered briefly across his field of consciousness; then came Elara, Lysithea, Himalia, and Leda at half their distance from Jupiter. He ignored them all; now the pock-marked face of Callisto lay ahead.

  Once, twice, he orbited the battered globe, larger than Earth's own Moon, while senses of which he had been unaware probed its outer layers of ice and dust. His curiosity was quickly satisfied; the world was a frozen fossil, still bearing the marks of collisions that, aeons ago, must have come close to shattering it. One hemisphere was a giant bull's-eye, a series of concentric rings where solid rock had once flowed in kilometre-high ripples under some ancient hammer blow from space.

  Seconds later, he was circling Ganymede. Now there was a far more complex and interesting world; though so near to Callisto, and almost the same size, it presented an utterly different appearance. There were, it was true, numerous craters – but most of them seemed to have been, quite literally, ploughed back into the ground. The most extraordinary feature of the Ganymedean landscape was the presence of meandering stripes, built up from scores of parallel furrows a few kilometres apart. This grooved terrain looked as if it had been produced by armies of intoxicated ploughmen, weaving back and forth across the face of the satellite.

  In a few revolutions, he saw more of Ganymede than all the space probes ever sent from Earth, and filed away the knowledge for future use. One day it would be important; he was sure of that, though he did not know why – any more than he understood the impulse that was now driving him so purposefully from world to world.

  As, presently, it brought him to Europa. Though he was still largely a passive spectator, he was aware now of a rising interest, a focusing of attention – a concentration of will. Even if he was a puppet in the hands of an unseen and uncommunicative master, some of the thoughts of that controlling influence leaked – or were allowed to leak – into his own mind.

  The smooth, intricately patterned globe now, rushing toward him bore little resemblanc
e either to Ganymede or Callisto. It looked organic; the network of lines branching and intersecting over its entire surface was uncannily like a world-spanning system of veins and arteries.

  The endless ice fields of a frigid waste, far colder than the Antarctic, stretched beneath him. Then, with brief surprise, he saw that he was passing over the wreckage of a spaceship. He recognized it instantly as the ill-fated Tsien, featured in so many of the video newscasts he had analysed. Not now – not now – there would be ample opportunity later.

  Then he was through the ice, and into a world as unknown to his controllers as to himself.

  It was an ocean world, its hidden waters protected from the vacuum of space by a crust of ice. In most places the ice was kilometres thick, but there were lines of weakness where it had cracked open and torn apart. Then there had been a brief battle between two implacably hostile elements that came into direct contact on no other world in the Solar System. The war between Sea and Space always ended in the same stalemate; the exposed water simultaneously boiled and froze, repairing the armour of ice.

  The seas of Europa would have frozen completely solid long ago without the influence of nearby Jupiter. Its gravity continually kneaded the core of the little world; the forces that convulsed Io were working there, though with much less ferocity. As he skimmed across the face of the deep, he saw everywhere the evidence of that tug-of-war between planet and satellite.

  And he both heard and felt it, in the continual roar and thunder of submarine earthquakes, the hiss of escaping gases from the interior, the infrasonic pressure waves of avalanches sweeping over the abyssal plains. By comparison with the tumultuous ocean that covered Europa, even the noisy seas of Earth were silent.

  He had not lost his sense of wonder, and the first oasis filled him with delighted surprise. It extended for almost a kilometre around a tangled mass of pipes and chimneys deposited by mineral brines gushing from the interior. Out of that natural parody of a Gothic castle, black, scalding liquids pulsed in a slow rhythm, as if driven by the beating of some mighty heart. And, like blood, they were the authentic sign of life itself.
