He broke the circuit; and as the image of the two astonished scientists faded, peace came flooding back into his soul.

  Imperceptibly, spring merged into summer. The eagerly awaited Bicentenary celebrations came and went; for the first time in years, he was able to enjoy Independence Day as a private citizen. Now he could sit back and watch the others perform—or he could ignore them if he wished.

  Because the ties of a lifetime were too strong to break, and it would be his last opportunity to see many old friends, he spent hours looking in on both conventions and listening to the commentators. Now that he saw the whole world beneath the light of Eternity, his emotions were no longer involved; he understood the issues, and appreciated the arguments, but already he was as detached as an observer from another

  planet. The tiny, shouting figures on the screen were amusing marionettes, acting out roles in a play that was entertaining, but no longer important—at least, to him.

  But it was important to his grandchildren, who would one day move out onto this same stage. He had not forgotten that; they were his share of the future, whatever strange form it might take. And to understand the future, it was necessary to know the past.

  He was taking them into that past, as the car swept along Memorial Drive. Diana was at the wheel, with Irene beside her, while he sat with the children, pointing out the familiar sights along the highway. Familiar to him, but not to them; even if they were not old enough to understand all that they were seeing, he hoped they would remember.

  Past the marble stillness of Arlington (he thought again of Martin, sleeping on the other side of the world) and up into the hills the car wound its effortless way. Behind them, like a city seen through a mirage, Washington danced and trembled in the summer haze, until the curve of the road hid it from view.

  It was quiet at Mount Vernon; there were few visitors so early in the week. As they left the car and walked toward the house, Steelman wondered what the first President of the United States would have thought could he have seen his home as it was today. He could never have dreamed that it would enter its second century still perfectly preserved, a changeless island in the hurrying river of time.

  They walked slowly through the beautifully proportioned rooms, doing their best to answer the children's endless questions, trying to assimilate the flavor of an infinitely simpler, infinitely more leisurely mode of life. (But had it seemed simple or leisurely to those who lived it?) It was so hard to imagine a world without electricity, without radio, without any power save that of muscle, wind, and water. A world where nothing moved faster than a running horse, and most men died within a few miles of the place where they were born.

  The heat, the walking, and the incessant questions proved

  more tiring than Steelman had expected. When they had reached the Music Room, he decided to rest. There were some attractive benches out on the porch, where he could sit in the fresh air and feast his eyes upon the green grass of the lawn.

  "Meet me outside," he explained to Diana, "when you've done the kitchen and the stables. I'd like to sit down for a while."

  "You're sure you're quite all right?" she said anxiously.

  "I never felt better, but I don't want to overdo it. Besides, the kids have drained me dry—I can't think of any more answers. You'll have to invent some; the kitchen's your department, anyway."

  Diana smiled.

  "I was never much good in it, was I? But I'll do my best—I don't suppose we'll be more than thirty minutes."

  When they had left him, he walked slowly out onto the lawn. Here Washington must have stood, two centuries ago, watching the Potomac wind its way to the sea, thinking of past wars and future problems. And here Martin Steelman, thirty-eighth President of the United States, might have stood a few months hence, had the fates ruled otherwise.

  He could not pretend that he had no regrets, but they were very few. Some men could achieve both power and happiness, but that gift was not for him. Sooner or later, his ambition would have consumed him. In the last few weeks he had known contentment, and for that no price was too great.

  He was still marveling at the narrowness of his escape when his time ran out and Death fell softly from the summer sky.

  Colombo July 1960

  I

  Who's There?

  When Satellite Control called me, I was writing up the day's progress report in the Observation Bubble—the glass-domed office that juts out from the axis of the space station like the hubcap of a wheel. It was not really a good place to work, for the view was too overwhelming. Only a few yards away I could see the construction teams performing their slow-motion ballet as they put the station together like a giant jigsaw puzzle. And beyond them, twenty thousand miles below, was the blue-green glory of the full Earth, floating against the raveled star clouds of the Milky Way.

  "Station Supervisor here," I answered. "What's the trouble?"

  "Our radar's showing a small echo two miles away, almost stationary, about five degrees west of Sirius. Can you give us a visual report on it?"

  Anything matching our orbit so precisely could hardly be a meteor; it would have to be something we'd dropped—perhaps an inadequately secured piece of equipment that had drifted away from the station. So I assumed; but when I pulled out my binoculars and searched the sky around Orion, I soon found my mistake. Though this space traveler was man-made, it had nothing to do with us.

  "I've found it," I told Control. "It's someone's test satellite

  —cone-shaped, four antennas, and what looks like a lens system in its base. Probably U.S. Air Force, early nineteen-sixties, judging by the design. I know they lost track of several when their transmitters failed. There were quite a few attempts to hit this orbit before they finally made it."

  After a brief search through the files, Control was able to confirm my guess. It took a little longer to find out that Washington wasn't in the least bit interested in our discovery of a twenty-year-old stray satellite, and would be just as happy if we lost it again.

  "Well, we can't do that," said Control. "Even if nobody wants it, the thing's a menace to navigation. Someone had better go out and haul it aboard."

  That someone, I realized, would have to be me. I dared not detach a man from the closely knit construction teams, for we were already behind schedule—and a single day's delay on this job cost a million dollars. All the radio and TV networks on Earth were waiting impatiently for the moment when they could route their programs through us, and thus provide the first truly global service, spanning the world from Pole to Pole.

  "I'll go out and get it," I answered, snapping an elastic band over my papers so that the air currents from the ventilators wouldn't set them wandering around the room. Though I tried to sound as if I was doing everyone a great favor, I was secretly not at all displeased. It had been at least two weeks since I'd been outside; I was getting a little tired of stores schedules, maintenance reports, and all the glamorous ingredients of a Space Station Supervisor's life.

  The only member of the staff I passed on my way to the air lock was Tommy, our recently acquired cat. Pets mean a great deal to men thousands of miles from Earth, but there are not many animals that can adapt themselves to a weightless environment. Tommy mewed plaintively at me as I clambered into my space suit, but I was in too much of a hurry to play with him.

  At this point, perhaps I should remind you that the suits we

  I

  use on the station are completely different from the flexible] affairs men wear when they want to walk around on the Moon. Ours are really baby spaceships, just big enough to hold one man. They are stubby cylinders, about seven feet long, fitted with low-powered propulsion jets, and have a pair of accordion-like sleeves at the upper end for the operator's arms. Normally, however, you keep your hands drawn inside the suit, working the manual controls in front of your chest.

  As soon as I'd settled down inside my very exclusive spacecraft, I switched on power and checked the gauges on the tiny ins
trument panel. There's a magic word, "FORB," that you'll often hear spacemen mutter as they climb into their suits; it reminds them to test fuel, oxygen, radio, batteries. All my needles were well in the safety zone, so I lowered the transparent hemisphere over my head and sealed myself in. For a short trip like this, I did not bother to check the suit's internal lockers, which were used to carry food and special equipment for extended missions.

  As the conveyor belt decanted me into the air lock, I felt like an Indian papoose being carried along on its mother's back. Then the pumps brought the pressure down to zero, the outer door opened, and the last traces of air swept me out into the stars, turning very slowly head over heels.

  The station was only a dozen feet away, yet I was now an independent planet—a little world of my own. I was sealed up in a tiny, mobile cylinder, with a superb view of the entire Universe, but I had practically no freedom of movement inside the suit. The padded seat and safety belts prevented me from turning around, though I could reach all the controls and lockers with my hands or feet.

  In space, the great enemy is the sun, which can blast you to blindness in seconds. Very cautiously, I opened up the dark filters on the "night" side of my suit, and turned my head to look out at the stars. At the same time I switched the helmet's external sunshade to automatic, so that whichever way the suit gyrated my eyes would be shielded from that intolerable glare.

  Presently, I found my target—a bright fleck of silver whose metallic glint distinguished it clearly from the surrounding stars. I stamped on the jet-control pedal, and felt the mild surge of acceleration as the low-powered rockets set me moving away from the station. After ten seconds of steady thrust, I estimated that my speed was great enough, and cut off the drive. It would take me five minutes to coast the rest of the way, and not much longer to return with my salvage.

  And it was at that moment, as I launched myself out into the abyss, that I knew that something was horribly wrong.

  It is never completely silent inside a space suit; you can always hear the gentle hiss of oxygen, the faint whirr of fans and motors, the susurration of your own breathing—even, if you listen carefully enough, the rhythmic thump that is the pounding of your heart. These sounds reverberate through the suit, unable to escape into the surrounding void; they are the unnoticed background of life in space, for you are aware of them only when they change.

  They had changed now; to them had been added a sound which I could not identify. It was an intermittent, muffled thudding, sometimes accompanied by a scraping noise, as of metal upon metal.

  I froze instantly, holding my breath and trying to locate the alien sound with my ears. The meters on the control board gave no clues; all the needles were rock-steady on their scales, and there were none of the flickering red lights that would warn of impending disaster. That was some comfort, but not much. I had long ago learned to trust my instincts in such matters; their alarm signals were flashing now, telling me to return to the station before it was too late. . . .

  Even now, I do not like to recall those next few minutes, as panic slowly flooded into my mind like a rising tide, overwhelming the dams of reason and logic which every man must erect against the mystery of the Universe. I knew then what it was like to face insanity; no other explanation fitted the facts.

  For it was no longer possible to pretend that the noise dis-

  turbing me was that of some faulty mechanism. Though I was in utter isolation, far from any other human being or indeed any material object, I was not alone. The soundless void was bringing to my ears the faint but unmistakable stirrings of life.

  In that first, heart-freezing moment it seemed that something was trying to get into my suit—something invisible, seeking shelter from the cruel and pitiless vacuum of space. I whirled madly in my harness, scanning the entire sphere of vision around me except for the blazing, forbidden cone toward the sun. There was nothing there, of course. There could not be—yet that purposeful scrabbling was clearer than ever.

  Despite the nonsense that has been written about us, it is not true that spacemen are superstitious. But can you blame me if, as I came to the end of logic's resources, I suddenly remembered how Bernie Summers had died, no farther from the station than I was at this very moment?

  It was one of those "impossible" accidents; it always is. Three things had gone wrong at once. Bernie's oxygen regulator had run wild and sent the pressure soaring, the safety valve had failed to blow—and a faulty joint had given way instead. In a fraction of a second, his suit was open to space.

  I had never known Bernie, but suddenly his fate became of overwhelming importance to me—for a horrible idea had come into my mind. One does not talk about these things, but a damaged space suit is too valuable to be thrown away, even if it has killed its wearer. It is repaired, renumbered—and issued to someone else. . . .

  What happens to the soul of a man who dies between the stars, far from his native world? Are you still here, Bernie, clinging to the last object that linked you to your lost and distant home?

  As I fought the nightmares that were swirling around me— for now it seemed that the scratchings and soft rumblings were coming from all directions—there was one last hope to which I clung. For the sake of my sanity, I had to prove that

  this wasn't Bernie's suit—that the metal walls so closely wrapped around me had never been another man's coffin.

  It took me several tries before I could press the right button and switch my transmitter to the emergency wave length. "Station!" I gasped. "I'm in trouble! Get records to check my suit history and—"

  I never finished; they say my yell wrecked the microphone. But what man alone in the absolute isolation of a space suit would not have yelled when something patted him softly on the back of the neck?

  I must have lunged forward, despite the safety harness, and smashed against the upper edge of the control panel. When the rescue squad reached me a few minutes later, I was still unconscious, with an angry bruise across my forehead.

  And so I was the last person in the whole satellite relay system to know what had happened. When I came to my senses an hour later, all our medical staff was gathered around my bed, but it was quite a while before the doctors bothered to look at me. They were much too busy playing with the three cute little kittens our badly misnamed Tommy had been rearing in the seclusion of my space suit's Number Five Storage Locker.

  Dallas February 1958

  Before Eden

  Like "I Remember Babylon," this was intended as a cautionary tale, though, as usual, Wells was the first to warn of planetary contamination in The War of the Worlds.

  Today, there is an international committee (CETEX) studying the subject, NASA has a "Planetary Quarantine" officer on its headquarters staff, and Sir Bernard Lovell castigates the Russians for dropping unsterilized probes on Venus.

  The USSR has since claimed that its first Venus lander was properly sterilized. If it is wrong, the events in this story may already have happened.

  "I guess," said Jerry Garfield, cutting the engines, "that this is the end of the line." With a gentle sigh, the underjets faded out; deprived of its air cushion, the scout car Rambling Wreck settled down upon the twisted rocks of the Hesperian Plateau.

  There was no way forward; on neither its jets nor its tractors could S.5—to give the Wreck its official name—scale the escarpment that lay ahead. The South Pole of Venus was only thirty miles away, but it might have been on another planet. They would have to turn back, and retrace their four-hundred-mile journey through this nightmare landscape.

  The weather was fantastically clear, with visibility of almost a thousand yards. There was no need of radar to show the cliffs ahead; for once, the naked eye was good enough. The green auroral light, filtering down through clouds that had rolled unbroken for a million years, gave the scene an underwater appearance, and the way in which all distant ob-

  jects blurred into the haze added to the impression. Sometimes it was easy to believe that they were
driving across a shallow sea bed, and more than once Jerry had imagined that he had seen fish floating overhead.

  "Shall I call the ship, and say we're turning back?" he asked.

  "Not yet," said Dr. Hutchins. "I want to think."

  Jerry shot an appealing glance at the third member of the crew, but found no moral support there. Coleman was just as bad; although the two men argued furiously half the time, they were both scientists and therefore, in the opinion of a hardheaded engineer-navigator, not wholly responsible citizens. If Cole and Hutch had bright ideas about going forward, there was nothing he could do except register a protest.

  Hutchins was pacing back and forth in the tiny cabin, studying charts and instruments. Presently he swung the car's searchlight toward the cliffs, and began to examine them carefully with binoculars. Surely, thought Jerry, he doesn't expect me to drive up there! S.5 was a hover-track, not a mountain goat. . . .

  Abruptly, Hutchins found something. He released his breath in a sudden explosive gasp, then turned to Coleman.

  "Look!" he said, his voice full of excitement. "Just to the left of that black mark! Tell me what you see."

  He handed over the glasses, and it was Coleman's turn to stare.

  "Well I'm damned," he said at length. "You were right. There are rivers on Venus. That's a dried-up waterfall."

  "So you owe me one dinner at the Bel Gourmet when we get back to Cambridge. With champagne."

  "No need to remind me. Anyway, it's cheap at the price. But this still leaves your other theories strictly on the crackpot level."
