01-Human Space Read online

  Something heavy is nosing up against me, I feel its weight against my back and the backs of my legs. What is it? Why am I not terrified?

  It slides around in front of me, questing. It looks like a huge amoeba, shapeless and translucent, with darker bodies showing within it. I’d guess it’s about my own weight.

  Life on Pluto! But how? Superfluids? Helium II contaminated by complex molecules? In that case the beast had best get moving; it will need shade come sunrise. Sunside temperature on Pluto is all of 50 degrees Absolute.

  No, come back! It’s leaving, flowing down toward the splash crater. Did my thoughts send it away? Nonsense. It probably didn’t like the taste of me. It must be terribly slow, that I can watch it move. The beast is still visible, blurred because I can’t look directly at it, moving downhill toward the landing vehicle and the tiny statue to the first man to die on Pluto.

  After the fiasco with the Nerva-K, one of us had to go down and see how much damage had been done. That meant tunneling down with the flame of a jet backpack, then crawling under the landing skirt. We didn’t talk about the implications. We were probably dead. The man who went down into the bubble cavity was even more probably dead; but what of it? Dead is dead.

  I feel no guilt. I’d have gone myself if I’d lost the toss.

  The Nerva-K had spewed fused bits of the fission pile all over the bubble cavity. We were trapped for good. Rather, I was trapped, and Jerome was dead. The bubble cavity was a hell of radiation.

  Jerome had been swearing softly as he went in. He came out perfectly silent. He’d used up all the good words on lighter matters, I think.

  I remember I was crying, partly from grief and partly from fear. I remember that I kept my voice steady in spite of it. Jerome never knew. What he guessed is his own affair. He told me the situation, he told me good- bye, and then he strode out onto the ice and took off his helmet. A fuzzy white ball engulfed his head, exploded outward, then settled to the ground in microscopic snowflakes.

  But all that seems infinitely remote. Jerome stands out there with his helmet clutched in his hands: a statue to himself, the first man on Pluto. A frost of recondensed moisture conceals his expression.

  Sunrise. I hope the amoeba—

  That was wild. The sun stood poised for an instant, a white point-source between twin peaks. Then it streaked upward—and the spinning sky jolted to a stop. No wonder I didn’t catch it before-It happened so fast.

  A horrible thought. What has happened to me could have happened to Jerome! I wonder—

  There was Sammy in the Earth-return vehicle, but he couldn’t get down to me. I couldn’t get up. The life system was in good order, but sooner or later I would freeze to death or run out of air.

  I stayed with the landing vehicle about thirty hours, taking ice and soil samples, analyzing them, delivering the data to Sammy via laser beam; delivering also high- minded last messages, and feeling sorry for myself. On my trips outside I kept passing Jerome’s statue. For a corpse, and one which has not been prettified by the post surgical skills of an embalmer, he looks damn good. His frost-dusted skin is indistinguishable from marble, and his eyes are lifted toward the stars in poignant yearning. Each time I passed him I wondered how I would look when my turn came.

  “You’ve got to find an oxygen layer,” Sammy kept saying.

  “Why?”

  “To keep you alive! Sooner or later they’ll send a rescue ship. You can’t give up now!”

  I’d already given up. There was oxygen, but there was no such layer as Sammy kept hoping for. There were veins of oxygen mixed with other things, like veins of gold ore in rock. Too little, too finely distributed.

  “Then use the water ice! That’s only poetic justice, isn’t it? You can get the oxygen out by electrolysis!”

  But a rescue ship would take years. They’d have to build it from scratch, and redesign the landing vehicle too. Electrolysis takes power, and heat takes power. I had only the batteries.

  Sooner or later I’d run out of power. Sammy couldn’t see this. He was more desperate than I was. I didn’t run out of last messages; I stopped sending them because they were driving Sammy crazy.

  I passed Jerome’s statue one time too many, and an idea came.

  This is what comes, of not wanting to die.

  In Nevada, three billion miles from here, half a million corpses lie frozen in vaults surrounded by liquid nitrogen. Half a million dead men wait for an earthy resurrection, on the day medical science discovers how to unfreeze them safely, how to cure what was killing each one of them, how to cure the additional damage done by ice crystals breaking cell walls all through their brains and bodies.

  Half a million fools? But what choice did they have? They were dying.

  I was dying.

  A man can stay conscious for tens of seconds in vacuum. If I moved fast, I could got out of my suit in that time. Without that insulation to protect me, Pluto’s black night would suck warmth from my body in seconds. At 50 degrees Absolute, I’d stay in frozen storage until one version or another of the Day of Resurrection.

  Sunlight—

  —And stars. No sign of the big blob that found me so singularly tasteless yesterday. But I could be looking in the wrong direction.

  I hope it got to cover.

  I’m looking east, out over the splash plain. In my peripheral vision the ship looks unchanged and undamaged.

  My suit lies beside me on the ice. I stand on a peak of black rock, poised in my silvered underwear, looking eternally out at the horizon. Before the cold touched my brain I found a last moment in which to assume a heroic stance. Go east, young man. Wouldn’t you know I’d get my directions mixed? But the fog of my breathing-air hid everything, and I was moving in terrible haste.

  Sammy Cross must be on his way home now. He’ll tell them where I am.

  Stars pour up from behind the mountains. The mountains and the splash plain and Jerome and I sink endlessly beneath the sky.

  My corpse must be the coldest in history. Even the hopeful dead of Earth are only stored at liquid nitrogen temperatures. Pluto’s night makes that look torrid, after the 50 degrees Absolute heat of day seeps away into space.

  A superconductor is what I am. Sunlight raises the temperature too high, switching me off like a damned machine at every dawn. But at night my nervous system becomes a superconductor. Currents flow; thoughts flow; sensations flow. Sluggishly. The one hundred and fifty-three hours of Pluto’s rotation flash by in what feels like fifteen minutes. At that rate I can wait it out.

  I stand as a statue and a viewpoint. No wonder I can’t get emotional about anything. Water is a rock here, and my glands are contoured ice within me. But I feel sensations: the pull of gravity, the pain in my ears, the tug of vacuum over every square inch of my body. The vacuum will not boil my blood. But the tensions are frozen into the ice of me, and my nerves tell me so. I feel the wind whistling from my lips, like an exhalation of cigarette smoke.

  This is what comes of not wanting to die. What a joke if I got my wish!

  Do you suppose they’ll find me? Pluto’s small for a planet. For a place to get lost in, a small planet is all too large. But there’s the ship.

  Though it seems to be covered with frost. Vaporized gases recondensed on the hull. Gray-white on gray- white, a lump on a dish of refrozen ice. I could stand here forever waiting for them to pick my ship from its surroundings.

  Stop that.

  Sunlight—

  Stars rolling up the sky. The same patterns, endlessly rolling up from the same points. Does Jerome’s corpse live the same half-life I live now? He should have stripped, as I did. My God! I wish I’d thought to wipe the ice from his eyes!

  I wish that superfluid blob would come back.

  Damn. It’s cold.

  Eye of an Octopus

  It was a well.

  Henry Bedrosian and Christopher Luden bent over the lip, peering down into the jet darkness. Their balloon-tired motorcycle lay forgotten on the
talcum sand, fine pink sand that stretched endlessly away to the flat horizon, borrowing its color from the sky. The sky was the color of blood. It might have been a flaming Kansas sunset, but the tiny sun was still at the zenith. The translucent hewn stone of the well-mouth stood like a blasphemy in the poisonous wilderness that was Mars.

  It stood four feet above the sand, roughly circular, perhaps three yards across. The weathered stones were upright blocks, a foot tall by five inches wide by perhaps a foot thick. Whatever the material of those stones, they seemed to glow with a faintly blue inner light.

  “It’s so human!” said Henry Bedrosian. His voice held a touch of bewildered frustration, echoed by his dark, chisel-nosed face.

  Chris Luden knew what he meant. “It’s natural. A well’s like a lever or a wheel. There aren’t many changes you can make, because it’s too simple. Did you notice the shape of the bricks?”

  “Yes. Odd. But they could still be man-made.”

  “In this air? Breathing nitric acid, drinking red fuming nitric acid? But—” Chris drew a deep breath. “Why complain? It’s life, Harry! We’ve discovered intelligent life!”

  “We've got to tell Abe.”

  “Right.”

  But it was a long moment before either moved. They stood leaning over the well, vivid green pressure suits against pink sand and dark red horizon, peering down into the blur of darkness at the bottom. Then they turned and mounted the Marsmobile.

  The landing vehicle stood like an upright steel ball- point pen. Its bottom half was three spreading legs, a restarting solid rocket, and a spacious cargo hold, two- thirds empty now. The upper half was the return-to-orbit stage. Far away across the crescent dunes was a white patch, the jettisoned drag chute.

  The Marsmobile, a glorified two-seater motorcycle with big round tires and a number of special modifications, putt-putted up to a landing leg and stopped. Henry got off and climbed to the cabin to call Abe Cooper in the orbiter. Chris Luden mounted to the cargo hold and rummaged through a disorganized hash of necessities until he had a long coil of thin line, a metal bucket, and a heavy rock hammer, all treated to resist the corrosive atmosphere. He dropped the objects next to the Marsmobile and climbed down. “Now we’ll see,” he told himself.

  Henry descended the ladder. “Abe’s having kittens,” he reported. “He says if we don’t call him every five minutes he’ll come down after us. He wants to know, how old is the well?”

  “So do I.” Chris brandished the hammer. “We’ll knock a chip off and analyze it. Let’s go.”

  The well was a mile and a half from the ship, and not of a conspicuous color. Probably they would have lost it if they hadn’t left a flag to mark it.

  “Let’s see how deep it is first,” said Luden. He put the hammer in the bucket for a weight, tied a line to the handle and let it fall. In the eery silence of the Martian desert they waited, listening …

  The rope was nearly gone when the bucket struck something. In a moment the ghost of a splash came floating up from the depths. Henry marked the line so they could measure how deep it had gone. It looked about three hundred feet. They hauled it up.

  The bucket was half full of a cloudy, slightly oily fluid.

  Chris handed it to his partner. “Harry, you want to take this back and analyze it?”

  Henry’s dark face grinned around the pointed beard. “I’ll match you for it. We both know what it’s gonna be.”

  “Sure, but it has to be done. Even.” They matcbed fingers. Henry lost. He rode back to the ship, the bucket dangling from one hand, fluid slopping over the edge.

  The stone which formed the well might have been quartz, or even some kind of unveined marble. It had been too badly weathered, too finely scored and polished and etched by the patient sand grains, to tell what it was. Chris Luden picked a likely looking block and brought the hammer down hard on what seemed to be a crack. He did it three times.

  The hammer was ruined.

  Luden shifted the hammer this way and that to examine the uneven, dulled edge and flattened corners. His blue eyes held a puzzled look. He knew the government might have quibbled about the weight of a tool for the Mars Project, but never the cost or quality. Here on Mars that hammer was worth tens of thousands of dollars. It must be made of some hard, durable steel alloy. Then —

  He cocked his head in his helmet, tasting a strange idea … “Harry!”

  “Yeah?”

  “How you doing?”

  “I’m just coming in the airlock. Give me five minutes to flnd out that this stuff is nitric acid.”

  “Okay, but do me a favor. Have you got your ring?”

  “The diamond horseshoe? Sure.”

  “Bring it back with you, outside your suit. Outside, that is.”

  “Now wait a minute, Chris. That’s a valuable ring. Why not use your own?”

  “I should have thought of that! I’ll just take off my pressure suit and—Uh! Can’t seem to got my helmet unfastened—”

  “Stop! Stop! I get the point.” There was a click as Henry’s radio went off.

  Luden sat down to wait.

  The sun was sliding toward the horizon. They had landed shortly before sunset yesterday, so they knew how suddenly the desert could turn from pink to midnight black, and how little light the insignificant moons gave. But sundown was four hours away.

  The dunes all faced the same way, perfect crescents, as regular as if hand-made. Something must shape the winds here, causing them to blow always in one direction, like Earth’s trade winds. And the dunes would crawl across the sands, slower than snails, following the winds.

  How old were the stones against his back? If they were really—a strange and silly thought, but Chris wouldn’t have volunteered for the Mars Project if he were not half a romantic—if they were really diamond, they must be terribly old, to be so worn by mere sand. Far older than the pyramids, and revered ancestor to the Sphinx. Maybe the race that carved those stones had since perished. Science-fiction writers often assumed an extinct Martian race. Why, perhaps the well had originally held water—

  “Hello, Chris?”

  “Here.”

  “It’s dirty nitric acid, not too strong. Next time you’ll believe me.”

  “Harry, they didn’t send us here to make astute guesses. They did all the guessing when they built the ship. We came to find out for sure, right? Right.”

  “See you in ten minutes.” Click.

  Luden let his eyes drift back across the desert. It was a moment before he realized what had caught his eye. One of the dunes was irregular. The curves were wrong, asymmetrical. The normal crescent had left one sprawling, trailing arm. It stood out like a pear in a line of apples.

  He had ten minutes, and the dune wasn’t far. Luden got up and started walking.

  He stood under the dune and looked back. The well was clearly visible. The distance was even shorter than he had thought. He had been deceived by the nearness of the horizon.

  The lip of the dune was some fourteen feet high.

  What had distorted it? An upthrusting spire of rock, perhaps, not quite high enough to show through the sand. They could find it with the sonar later.

  It had to be under the one sprawling, twisted arm of sand.

  “Chris! Where the hell are you? Chris?”

  Chris jumped. He’d forgotten Henry. “Look due south of the well and you’ll see me.”

  “Why don’t you stay where you’re put, you idiot? I thought you’d been buried by a sandstorm.”

  “Sorry, Harry. I got interested in something.” Chris Luden was now standing on the twisted arm of sand. He sounded preoccupied. “Try scratching the blocks of the well with your ring.”

  “That’s an odd thought” Henry laughed.

  “Do it”

  Silence. Luden felt the wind, looked down at the sand, tried to imagine what obstruction had dropped here. Something not necessarily very large. It would be beneath the dune; it would be on the windward side … at the beginning of
the arch … there.

  “I scratched it, Chris. “There’s a scratch all right. So that effectively takes … ooops. Aaargh! Chris, you’re doomed! Only death can save you from my wrath!”

  “Why are you irritated with—”

  “My diamond! It’s ruined!”

  “Relax. You could replace it a million times over with just one block from the well.”

  “Say, that’s true. But we’ll need the laser to cut it loose. They must have used diamond dust for the cement, too. And the fuel to get it back—”

  “Harry, do me a favor. Bring—”

  “That last favor cost me a three-thousand-dollar ring!”

  “Bring the Marsmobile out here. I want to do some digging.”

  “Be right there.”

  A minute later Henry stopped the machine alongside Chris’s green suit. His smile showed that the scratches on his ring had not permanently scarred his psyche. “Where do we dig?”

  "Right where I’m standing.”

  The Marsmobile was equipped with two down-thrusting compressed-air jets for getting over steep obstructions. A large tank under the vehicle’s belly held the heavily compressed air, compressed directly from the thin Martian atmosphere by the motor. Henry turned on the jets and hovered over the spot where Chris had been standing, shifting his weight to keep the machine in place. Sand sprayed out in sheets. Chris ran to get out from under, and Henry grinned and doubled the thrust to send the fine grains showering over him.

  In half a minute the pressure became too low. Henry had to land. The Marsmobile shuddered and vibrated as its motor struggled to refill the pressure chamber.

  “I hate to ask,” said Henry, “but what’s the point of all this?”

  “There’s something solid down there. I want to expose it.”

  “Okay, if you’re sure were in the right place. We’ve got six months of time to waste.”

  They wasted a few minutes silently watching the Marsmobile fill its pressure tank.

  “Hey,” said Henry. “You think we could stake a claim on this diamond mine?”
