"What do you mean?" Senator Floyd, rather sharply.
"The stars, of course," answered Bruno, warming up to one of his favorite subjects. "We've found no intelligent life on the other planets of our own sun, so we'll have to look farther afield. How exciting it will be, to meet creatures wiser than us, yet perhaps using wholly different thought processes! We believe our systems of logic-and the ones we build into robots like Socrates-are universal but we can't be sure. The answers to that, and to a lot of other questions, lie out in the stars."
"But most of the scientists who've been up before our committee," said Floyd, "believe that flight to the stars will always be impossible, because of the enormous distances. They say that any trip, with propulsion systems that we can imagine, will take thousands of years."
"What if it does?" answered Bruno. "The solution's right here. We're not sure if simple hibernation stops the aging process, but we're fairly certain that deep-freezing does-and there are groups working on that, at Bethesda and San Antonio. I can imagine a ship starting on a ten- thousand-year voyage, with robots like Socrates in charge until the time comes to thaw out the crew."
Senator Floyd seemed to be thinking this over; he appeared to have forgotten the demonstration that had been so carefully arranged for his benefit. For the first time Bruno realized that the Senator, whom he knew rather well, had been very preoccupied during his visit to the lab; he was not his usual inquisitive self. Or he had not been until this moment; now something seemed to have triggered him off.
"Let me get this straight," he continued. "You think that flight to the stars-not just to the planets-is possible, and that robots could be built that would operate for thousands of years?"
"Certainly."
"What about-millions of years?"
That's a damned odd question, thought Bruno, what the devil is the old boy driving at?
"I certainly wouldn't guarantee a million-year robot with our present materials and technologies," he answered cautiously. "But I can imagine a virtually immortal automaton, if its thinking circuits were properly encapsulated. A crystal-a diamond, for example-lasts a long, long time; and we've already started building memories into crystals."
"This is all very fascinating," interrupted Representative McBurney of New York, "but I'm not a robot, and it's past lunchtime." He pointed to Socrates, who had now emerged from the capsule and, his programmed demonstration completed, stood waiting further orders. "He may be satisfied with a few minutes plugged into a wall socket, but I want something more substantial."
"Eating food," said Bruno with a grin, "is a terribly inefficient and messy way of acquiring energy. Some of my friends in Biotechnology are trying to bypass it."
"Thanks for warning us-that's one project we won't support. I prefer the human body the way it is; and while we're on the subject, we do have another fundamental advantage over robots."
"And what's that?"
"We can be manufactured by unskilled labor."
Bruno dutifully joined in the laughter, though he had heard that particular joke a hundred times before and was just a little tired of it. Besides, what did it prove?
To Bruno, as to many of his colleagues, the machines with which he was working were a new species, free from the limitations, taints, and stresses of organic evolution. They were still primitive, but they would learn. Already they could handle problems of a complexity far beyond the scope of the human brain. Soon they would be designing their own successors, striving for goals which Homo sapiens might never comprehend.
Yes, it was true that-for a while-men would be able to outbreed robots, but far more important was the fact that one day robots would outthink men.
When that day came, Bruno hoped that they would still be on good terms with their creators.
FROM THE OCEAN, FROM THE STARS
Four thousand miles above the surface of Mars, experimental spacecraft Polaris 1-XE rested at the end of her maiden voyage. Her delicate, spindle-shaped body with its great radiating surfaces and ring of low-thrust ion engines would be torn to pieces by air resistance if she ever entered an atmosphere. She was a creature of deep space, and had been built in orbit around Earth; now she was as near to any world as she would ever be, suspended by a network of flimsy cables between two jagged peaks of Phobos, the inner satellite of Mars. On this fifteen-mile diameter ball of rock, the ship weighed only a few hundred pounds; for all practical purposes she and her crew were still in free orbit. Gravity here was little more than a thousandth of Earth's.
To David Bowman, now that his responsibility for the voyage was over, the spectacle of the red planet was a never-failing source of wonder. The glittering frost of the South Polar Cap, the brown and chocolate and green of the maria, the infinitely varied rosy hues of the deserts the movements of the occasional dust storms across the temperate zones-these were sights of which he never tired. Every seven hours the gigantic disk of the planet waned and waxed from full to new and back again; even when the dark side of Mars was turned toward them, it still dominated the sky, for it seemed as if a vast circular hole was moving across the stars, swallowing them up one by one.
David Bowman, biophysicist and cybernetics expert, still found it hard to believe that he was really floating here on one of the offshore islands of Mars-the planet that had dominated his youth. He had been born in Flagstaff, Arizona, where David Bowman Sr. had spent most of his working life at the Lowell Observatory, center of Martian research since long before the dawn of the space age. It seemed only a few years ago that they had both been present at the observatory's centenary celebrations in 1994.
Percival Lowell, Bowman often thought, was really a man of the Renaissance, born out of his time. Diplomat, orientalist, author, brilliant mathematician, and superb observer, Lowell had focused the attention of the scientific world upon Mars and its "canals" in the early 1900's. Though most of his conclusions were now known to be erroneous, he was one of the patron saints of Solar System studies, and had kept interest in the planets alive during the decades of neglect.
The splendid 24-inch refractor through which he had stared at Mars for countless hours was still in use. Now, a hundred years later, the largest settlement on that planet bore his name-and a man whose father had known Lowell's own colleagues would soon be walking on the world to which the great astronomer had devoted his life.
The older Bowman had hoped that his son would step into his place, but though the boy was fascinated by the stars and spent many nights at the observatory, his real interests lay in the behavior of living creatures. Inevitably, that had led him into cybernetics, and the shifting no- man's-land between the world of robots and the animal kingdom. He had helped to design the circuits and control mechanisms that made this ship almost a living entity, with a central nervous system, a computer brain, and sense organs that could reach out into space for a million miles around.
How strange that, after he had turned aside from astronomy, his work should have brought him out here to Mars! When the docking had been complete, he had radioed his father: JUST LANDED SAFELY PHOBOS. NATIVES FRIENDLY. HOPE YOU CAN SEE ME THROUGH 24 INCHER. DAVID.
Less than half an hour later had come the reply: SORRY FLAGSTAFF CLOUDY WILL TRY TOMORROW LOVE FROM ALL DAD.
And what, David Bowman asked himself, would old Percival Lowell have thought of that?
Now something else was coming through from Earth, most brilliant of all the stars in the Martian sky. The printer in the communications rack of the tiny satellite base-manned only when a ship was arriving or departing from orbit-gave the faint chime that indicated the end of the message. Bowman floated across to the rack, holding onto the guide rope with his right hand, and tore off the rectangle of paper.
He read the few lines of type several times before he could really believe them. Then he began to swear, rather competently, in English and Navajo.
He had traveled fifty million miles, and at this moment was no further from Mars than New York from London. In a few hours, h
e should have been taking the shuttle down to Port Lowell.
But now he was not going to Mars at all, there would be no time for that. For some incredible reason, Earth was calling homeward the latest and swiftest of all its ships.
Peter Whitehead received his orders on the shore of the Sea of Fire, where a monstrous sun hung forever bisected by the horizon.* He had been sent to Mercury to install and supervise the life-support system for the first manned base on the planet, in the narrow temperate zone at the edge of the Night Land. A few years hence, this would be the starting point for expeditions into the furnace of the day side, where metal could melt at the eternal noon. But before that time came, a foothold had to be secured on Mercury, and the silver-plated domes of Prime Base nestled in a small valley where the deadly sunlight would never shine. That light lay forever in a band of incandescence upon the peaks two thousand feet above the settlement, moving up and down slightly as the weeks passed and the planet rocked through its annual librations. The reflected glare from the mountains could do no harm; in the valley it provided a kind of perpetual moonlight, with only a trace of the murderous heat.
*While these words were being written, radio observers were discovering-to the embarrassed amazement of the astronomers-that Mercury does not keep the same face always turned toward the sun. This wiped out a whole category of science-fiction stories overnight, but makes very little difference to surface conditions on the planet.
Whitehead was not sorry to leave. He had done his job, and unless one was a geophysicist or a devoted solar observer, Mercury's peculiar charms soon waned. When he got back to Earth, he decided, he would like to take a vacation in Antarctica. But he suspected-correctly-that he was not going to have a holiday for quite some time.
Slightly closer to Earth, Victor Kaminski was in orbit a thousand miles about the dazzling white cloudscape of Venus. In the three months that he had been here, aboard Cytherean Station One, those clouds had never broken, and had shown only the most fugitive changes of color and shading. They were as eternal as the day-and the night-of Mercury; probably the sun's rays had not reached the surface of Venus since life began on Earth.
Nor had any men yet descended through those clouds, into the heat and darkness and pressure of the planet's hidden lands. But there were many instruments down there, sending up their reports to the space station, scanning and probing their hostile surroundings with radar, sound waves, neutron beams, and the other tools of planetary exploration. As information accumulated, so the personality of Earth's nearest neighbor slowly emerged; it was fascinating to see old mysteries resolved, and new ones loom up on the frontiers of knowledge. What, for example, could possibly cause that steady, continuous roaring at 125 North, 52 West? It sounded like a waterfall-but there could be no waterfalls on a world where the temperature was far above that of superheated steam. Microphones had pinpointed the source to within five kilometers, yet so far no probes had managed to locate it.
This was only one of the problems that made life exciting for Victor Kaminski, astronomer and planetologist. Venus was a strange, unfriendly world, yet he had fallen in love with her. (He never thought of the planet as anything but feminine.) And now, to his anger and disappointment, Earth was calling him back.
He did not know it yet, but he was after far bigger game.
Two miles from the Queensland coast, the hydroskimmer Bombora (Mario Lombini Pty., Coolangatta-Motor Repairs) gently rose and fell in the waters of the Great Barrier Reef. The three Lombini brothers, and the one Lombini sister, watched skeptically while their guest made the final adjustments to his new invention.
The object that William Hunter was kneeling beside looked, at first glance like a perfectly normal surfboard, painted a brilliant yellow. However, the curved leading edge was broken by a series of narrow slots, so that from the front it resembled an overgrown mouth-organ. There were two larger slots at the rear, on either side of the stabilizing fin.
Hunter turned a wide-bladed screwdriver, and a flush mounted panel opened in the underside of the board. The hollow interior held two slim gas cylinders and some neatly laid-out plumbing, as well as a few control wires and a tiny pressure gauge. After turning a valve and checking the gauge, he carefully replaced the panel.
"Stand back!" he warned, gripping the recessed handholds. There was a sudden high-pitched shriek of gas, and the board jerked like a living creature.
"Seems lively enough," said the satisfied inventor. "See if you can catch me."
He lowered the board into the water, lay flat upon it, and squeezed the throttle.
The smooth plastic shook and bucked beneath him, the oily, blue-green water slid by with satisfying swiftness inches beneath his nose. Leaving a wide, creamy wake, he took off in the general direction of New Zealand. He was too busy controlling the board to look back, but he knew that Bombora would be following on her cushion of air.
A great wave was humping up ahead; over or through? That was the problem, and Hunter usually made the wrong decision. He aimed the nose of the board slightly downward, took a deep breath, and squeezed the throttle controls.
A curving green wall rose above his head, and he slipped effortlessly through its surface into the roaring underwater world. For a few seconds the wave tugged him landward; then he was beyond its power and an instant later emerged, shaking the water from his eyes, on the other side.
He looked round for Bombora, but there was no time to locate her, for here came another wave, its wind-ripped crest hissing like a giant snake. Again he dived into the luminous green underworld, feeding the tiny hydrojets a three-second jolt of power.
He had almost lost count of the waves that had gone storming by when suddenly he was in quiet water, rising and falling on a gentle swell. Swinging the board around he looked back toward the coast-and swallowed hard
when he saw the huge, humped shoulders of the moving, liquid hills that now separated him from solid land. Where was Bombora?
Then he saw that the skimmer had used her speed to take a longer but smoother route out to sea, and had avoided the line of surf. He also saw that Mario was signaling to him-perhaps warning him not to attempt to shoot those waves. If the Aussies were nervous, he was certainly going to take no chances; he relaxed on the board, and waited.
Bombora came whistling up to him in a cloud of spray; and then, with a sinking heart, he saw that Mario was holding out the telephone.
"Call from Washington," said the senior Lombini, as he cut the engines and Bombora settled down on her floats. "I told them you weren't here, but it was no good."
He handed over the cordless receiver, and Hunter, still bobbing up and down on the board, heard the peremptory voice from the other side of the world. He answered dully: "Yes, sir-I'll be there at once," and then gave the instrument back to Mario.
Being the number one propulsion specialist of the Space Agency had its disadvantages. His holiday was over almost before it had begun, and the Lombini brothers would have to finish the development and marketing of the Squid. Worse still, his trip out to the Great Barrier Reef with Helena was also off, and he'd have to cancel their reservation on Heron Island.
Perhaps it was just as well, combining business with pleasure was seldom a very good idea. But that, he knew, was only sour grapes.
Twenty-two thousand miles above the earth, aboard Intelsat VIII, Jack Kimball had been rather more fortunate. It was not too easy to find privacy aboard the great floating raft which now handled most of the communications traffic of the Pacific area, but he and Irene Martinson had managed it, with most satisfactory results.
The ribald speculations which had grown with the Space Age were not altogether ill-founded. In the total absence of weight, some of the more exuberant fantasies of Indian temple art had moved into the realm of practical politics; one did not have to be an athlete to surpass anything that the ingenious sculptors of the great Konarak Temple at Puri had been able to contrive. And it was an interesting fact-which the psychologists had not overl
ooked-that reproductions of such art were rather popular in all the larger, permanently inhabited space stations.
There were those who argued that sex in zero gee was tantalizing, and not wholly satisfying. One school of thought insisted on at least a third of a gravity-which meant that its advocates would be happy on Mars, but permanently discontented on the Moon. As Kimball filed away his memories for future reference, he decided that those who felt this way had too many inhibitions, or too little ingenuity. Neither charge applied to him.
When they were both presentable again, he unlocked the door of the spacesuit storage locker. As he did so, Irene started giggling.
"Just suppose," she said, "that there'd been an emergency and everyone came rushing in here for suits."
"Well," grinned Jack, "we should have had a head start. When are you off duty again?"
Before she could reply, the corridor speaker cleared its throat and said firmly: "Dr. Kimball-please report to Control."
