"Hurry!"
"Gotta get my suit off." My hands had started to shake from reaction. I couldn't work the clamps.
"No you don't. If we start right now we may get home. Leave the suit on and come in."
I did. As I pulled my webbing shut, the rams roared. The s.h.i.+p shuddered a little, then pushed forward as we dropped from under the blimp tank. Pressure mounted as the rams reached operating speed. Eric was giving it all he had. It would have been uncomfortable even without the metal suit around me. With the suit on it was torture.
My couch was afire from the suit, but I couldn't get breath to say so. We were going almost straight up.
We had gone twenty minutes when the s.h.i.+p jerked like a galvanized frog.
"Ram's out," Eric said calmly.
"I'll use the other." Another lurch as we dropped the dead one. The s.h.i.+p flew on like a wounded penguin, but still accelerating. One minute... two... The other ram quit. It was as if we'd run into mola.s.ses. Eric blew off the ram and the pressure eased. I could talk.
"Eric."
"What?"
"Got any marshmallows?"
"What? Oh, I see. Is your suit tight?"
"Sure."
"Live with it. We'll flush the smoke out later. I'm going to coast above some of this stuff, but when I use the rocket it'll be savage. No mercy."
"Will we make it?"
"I think so. It'll be close."
The relief came first, icy cold. Then the anger.
"No more inexplicable numbnesses?" I asked.
"No. Why?"
"If any come up you'll be sure and tell me, won't you?"
"Are you getting at something?"
"Skip it." I wasn't angry any more.
"I'll be d.a.m.ned if I do. You know perfectly well it was mechanical trouble, you fool.
You fixed it yourself!"
"No. I convinced you I must have fixed it. You needed to believe the rams should be working again. I gave you a miracle cure, Eric. I just hope I don't have to keep dreaming up new placebos for you all the way home."
"You thought that, but you went out on the wing sixteen miles up?" Eric's machinery snorted.
"You've got guts where you need brains, Shorty."
I didn't answer.
"Five thousand says the trouble was mechanical. We let the mechanics decide after we land."
"You're on."
"Here comes the rocket. Two, one" It came, pus.h.i.+ng me down into my metal suit. Sooty flames licked past my ears, writing black on the green metal ceiling, but the rosy mist before my eyes was not fire.
The man with the thick gla.s.ses spread a diagram of the Venus s.h.i.+p and jabbed a stubby finger at the trailing edge of the wing.
"Right around here," he said.
"The pressure from outside compressed the wiring channel a little, just enough so there was no room for the wire to bend. It had to act as if it were rigid, see? Then when the heat expanded the metal these contacts pushed past each other."
"I suppose it's the same design on both wings?"
He gave me a queer look.
"Well, naturally."
I left my check for $5000 in a pile of Eric's mail and hopped a plane for Brasilia. How he found me I'll never know, but the telegram arrived this morning.
HOWIE COME HOME ALL IS FORGIVEN.
DONOVANS BRAIN.
I guess I'll have to.
Wait It Out NIGHT ON PLUTO. Sharp and distinct, the horizon line cuts across my field of vision.
Below that broken line is the dim gray-white of snow seen by starlight. Above, s.p.a.ce-blackness and s.p.a.ce-bright stars. From behind a jagged row of frozen mountains the stars pour up in singletons and cl.u.s.ters and streamers of cold white dots. Slowly they move, but visibly, just fast enough for a steady eye to capture their motion.
Something wrong there. Pluto's rotation period is long: 6.39 days. Time must have slowed for me.
It should have stopped.
I wonder if I may have made a mistake.
The planet's small size brings the horizon close. It seems even closer without a haze of atmosphere to fog the distances. Two sharp peaks protrude into the star swarm like the filed front teeth of a cannibal warrior. In the cleft between those peaks s.h.i.+nes a sudden bright point.
I recognize the Sun, though it shows no more disk than any other, dimmer star. The sun s.h.i.+nes as a cold point between the frozen peaks; it pulls free of the rocks and s.h.i.+nes in my eyes...
The Sun is gone, the star field has s.h.i.+fted. I must have pa.s.sed out.
It figures.
Have I made a mistake? It won't kill me if I have. It could drive me mad, though...
I don't feel mad. I don't feel anything, not pain, not loss, not regret, not fear. Not even pity. Just: what a situation.
Gray-white against gray-white: the landing craft, short and wide and conical, stands half-submerged in an icy plain below the level of my eyes. Here I stand, looking east, waiting.
Take a lesson: this is what comes of not wanting to die.
Pluto was not the most distant planet. It had stopped being that in 1979, ten years ago.
Now Pluto was at perihelion, as close to the Sun--and to Earth--as it would ever get. To ignore such an opportunity would have been sheer waste.
And so we came, Jerome and Sammy and I, in an inflated plastic bubble poised on an ion jet. We'd spent a year and a half in that bubble. After so long together, with so little privacy, perhaps we should have hated each other. We didn't. The UN psyche team must have chosen well.
But--just to be out of sight of the others, even for a few minutes. Just to have something to do, something that was not predictable. A new world could hold infinite sites. As a matter of fact, so could our laboratory-tested hardware. I don't think any of us really trusted the Nerva-K under our landing craft.
Think it through. For long trips in s.p.a.ce, you use an ion jet giving low thrust over long periods of time. The ion motor on our own craft had been decades in use. Where gravity is materially lower than Earth's, you land on dependable chemical rockets. For landings on Earth and Venus, you use heat s.h.i.+elds and the braking power of the atmosphere. For landing on the gas giants--but who would want to?
The Nerva-cla.s.s fission rockets are used only for takeoff from Earth, where thrust and efficiency count responsiveness and maneuverability count for too much during a powered landing. And a heavy planet will always have an atmosphere for braking.
Pluto didn't.
For Pluto, the chemical jets to take us down and bring us back up were too heavy to carry all that way. We needed a highly maneuverable Nerva-type atomic rocket motor using hydrogen for reaction ma.s.s.
And we had it. But we didn't trust it.
Jerome Gla.s.s and I went down, leaving Sammy Cross in orbit. He griped about that, of course. He'd started that back at the Cape and kept it up for a year and a half. But someone had to stay. Someone had to be aboard the Earth-return vehicle, to fix anything that went wrong, to relay communications to Earth, and to fire the bombs that would solve Pluto's one genuine mystery.
We never did solve that one. Where does Pluto get all that ma.s.s? The planet's a dozen times as dense as it has any right to be. We could have solved that with the bombs, the same way they solved the mystery of the makeup of the Earth, sometime in the last century. They mapped the patterns of earthquake ripples moving through the Earth's bulk. But those ripples were from natural causes, like the Krakatoa eruption. On Pluto the bombs would have done it better.
A bright star-sun blazes suddenly between two fangs of mountain. I wonder if they'll know the answers, when my vigil ends.
The sky jumps and steadies, and-- I'm looking east, out over the plain where we landed the s.h.i.+p. The plain and the mountains behind seem to be sinking like Atlantis: an illusion created by the flowing stars. We slide endlessly down the black sky, Jerome and I and the mired s.h.i.+p.
The Nerva-K behaved perfectly. We hovered for several minutes to melt our way through various layers of frozen gases and get ourselves something solid to land on.
Condensing volatiles steamed around us and boiled below, so that we settled in a soft white glow of fog lit by the hydrogen flame.
Black wet ground appeared below the curve of the landing skirt. I let the s.h.i.+p drop carefully, carefully... and we touched.
It took us an hour to check the s.h.i.+p and get ready to go outside. But who would be first?
This was no idle matter. Pluto would be the solar system's last outpost for most of future history, and the statue to the first man on Pluto would probably remain untarnished forever.
Jerome won the toss. All for the sake of a turning coin, Jerome would be the first name in the history books. I remember the grin I forced! I wish I could force one now. He was laughing and talking of marble statues as he went through the lock.
There's irony in that, if you like that sort of thing.
I was s.c.r.e.w.i.n.g down my helmet when Jerome started shouting obscenities into the helmet mike. I cut the checklist short and followed him out.
One look told it all.
The black wet dirt beneath our landing skirt had been dirty ice, water ice mixed haphazardly with lighter gases and ordinary rock. The heat draining out of the Nerva jet had melted that ice. The rocks within the ice had sunk, and so had the landing vehicle, so that when the water froze again it was halfway up the hull. Our landing craft was sunk solid in the ice.
We could have done some exploring before we tried to move the s.h.i.+p. When we called Sammy he suggested doing just that. But Sammy was up there in the Earth- return vehicle, and we were down here with our landing vehicle mired in the ice of another world.
We were terrified. Until we got clear we would be good for nothing, and we both knew it.
I wonder why I can't remember the fear.
We did have one chance. The landing vehicle was designed to move about on Pluto's surface; and so she had a skirt instead of landing jacks. Half a gravity of thrust would have given us a ground effect, safer and cheaper than using the s.h.i.+p like a ballistic missile. The landing skirt must have trapped gas underneath when the s.h.i.+p sank, leaving the Nerva-K engine in a bubble cavity.
We could melt our way out.
I know we were as careful as two terrified men could be. The heat rose in the Nerva-K, agonizingly slow. In flight there would have been a coolant effect as cold hydrogen fuel ran through the pile. We couldn't use that. But the environment of the motor was terribly cold. The two factors might compensate, or-- Suddenly dials went wild. Something had cracked from the savage temperature differential. Jerome used the damper rods without effect. Maybe they'd melted. Maybe wiring had cracked, or resistors had become superconductors in the cold. Maybe the pile- -but it doesn't matter now.
I wonder why I can't remember the fear.
Sunlight-- And a logy, dreamy feeling. I'm conscious again. The same stars rise in formation over the same dark mountains.
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 h.e.l.l 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, a.n.a.lyzing 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 pa.s.sing Jerome's statue. For a corpse, and one which has not been prettified by the post surgical skills of an embalmer, he looks d.a.m.n good. His frost-dusted skin is indistinguishable from marble, and his eyes are lifted toward the stars in poignant yearning. Each time I pa.s.sed him I wondered how I would look when my turn came.
