Year's Best Scifi 6 Part 30

All this was out of sight of Dan's cameras. She did not tell him what she had done. She could not leave her water habitat; yet she was able to explore.

Small firefly robots set off from the habitat, picking their way carefully over the surface of the asteroid. Each robot was laden with miniature instruments, as exquisite as coral, all beyond her understanding.

But the fireflies were under her control. She used the waldo, the glovelike device into which she could slip her long arms and so control the delicate motions of each firefly.

...Soon the babies were being hatched: popping out of their dissolving eggs one by one, wriggling away, alert, active, questioning. With gentle jets of water, she coaxed them towards sea gra.s.s.

Meanwhile, she had work to do.

Sheena sent the fireflies to converge at one pole of hReinmut. There, patiently, piece by piece, shehad them a.s.semble a small chemical factory, pipes and tanks and pumps, and a single flaring nozzle which pointed to the sky. Precious solar panels, spread over the dusty ground, provided power.

The factory began its work. Borers drew up surface regolith and the rock and ice which lay deeper within. Chemical separation processes filtered out methane ice and stored it, while other processes took water, ice, melted it and pa.s.sed it through electrical cells to separate it into its components, oxygen and hydrogen.

This whole process seemed remarkable to Sheena. To take rock and ice, and to transform it into other substances! But Dan told her that this was old, robust technology, practiced by NASA and other humans for many times even his long lifetime.

Mining asteroids was easy. You just had to get there and do it.

Meanwhile the young were growing explosively quickly, converting half of all the food they ate to body ma.s.s. She watched the males fighting: I am large and fierce. Look at my weapons. Look at me!

Most of the young were dumb. Four were smart.

She was growing old now, and tired easily. Nevertheless she taught the smart ones how to hunt. She taught them about the reef, the many creatures that lived and died there. And she taught them language, the abstract signs Dan had given her. Soon their mantles rippled with questions. Who? Why? Where?

What? How?

She did not always have answers. But she showed them the machinery that kept them alive, and taught them about the stars and sun, and the nature of the world and universe, and about humans.

At last the structure at the pole was ready for its test.

Under Sheena's control, simple valves clicked open. Gaseous methane and oxygen rushed together and burned in a stout chamber. Through robot eyes Sheena could see combustion products emerge, ice crystals that caught the sunlight, receding in perfectly straight lines. It was a fire fountain, quite beautiful.

And Sheena could feel the soft thrust of the rocket, the huge waves that pulsed slowly through the hab's water.

The methane rocket, fixed at the axis of the asteroid's spin, would push Reinmuth gradually out of its...o...b..t and send it to intercept Earth.

Dan told her there was much celebration, within NASA. He did not say so, but Sheena understood that this was mainly because she had finished her task before dying.

Now, she was no longer needed. Not by the humans, anyway.

The young ones seemed to understand, very quickly, that Sheena and all her young would soon exhaust the resources of this one habitat. Already there had been a number of problems with the tightly closed environment loops: unpredictable crashes and blooms in the phytoplankton population.

The young were very smart. Soon they were able to think in ways that were beyond Sheena herself.

For instance, they said, perhaps they should not simply repair this fabric sh.e.l.l, but extend it. Perhaps, said the young, they should even make new domes and fill them with water.

Sheena, trained only to complete her primary mission, found this a very strange thought.

But there weren't enough fish, never enough krill. The waters were stale and crowded.

This was clearly unacceptable.

So the smart young hunted down their dumb siblings, one by one, and consumed their pa.s.sive bodies, until only these four, and Sheena, were left.

When the storm broke, Dan Ystebo was in his cubicle in the science rooms at JPL, in the middle of an online conference on results from Reinmuth.

Maura Della stood over him, glaring.

He touched the softscreen to close down the link. "Senator-"

"You a.s.shole, Ystebo. How long have you known?"

He sighed. "Not long. A couple of weeks."

"Did you know she was pregnant before the launch?"

"No. I swear it. If I'd known I'd have scrubbed the mission."

"Don't you get it,Ystebo? We'd got to the point where the bleeding-heart public would haveaccepted Sheena's death. But this has changed everything..."

It's over, he thought, listening to her anger and frustration.

She visibly tried to calm down. "The thing is, Dan, we can't have that asteroid showing up in orbit with a cargo of sentient squid corpses. People would think it was monstrous." She blinked. "In fact, so would I."

He closed his eyes. "I don't suppose it's any use pointing out how stupid it is to stop now. We spent the money already. We have the installation on Reinmuth. It's working; all we have to do is wait for rendezvous. We achieved the goal, the bootstrap."

"It doesn't matter," she said gently, regretfully. "People are-not rational, Dan."

"And the future, the greater goal-"

"We're still engaged in a race between opportunity and catastrophe. We have to start again. Find some other way."

"This was the only chance. We just lost the race."

"I pray not," she said heavily. "Look-do it with decency. Let Sheena die in comfort. Then turn off the rockets."

"And the babies?"

"We can't save those either way, can we?" she said coolly. "I just hope they forgive us."

"I doubt that," Dan said.

The water which trickled through her mantle was cloudy and stank of decay. She drifted, aching arms limp, dreaming of a male with bright, mindless eyes.

But the young wouldn't let her alone.

Danger near. You die we die. They were flashing the fast, subtle signals employed by a shoal sentinel, warning of the approach of a predator.

There was no predator here, of course, save death itself.

She tried to explain it to them. Yes, they would all die- but in a great cause, so that Earth, NASA, the ocean, could live. It was a magnificent vision, worthy of the sacrifice of their lives.

Wasn't it?

But they knew nothing of Dan, of NASA, of Earth.

No. You die we die.

They were like her. But in some ways they were more like their father. Bright. Primal.

Dan Ystebo cleared his desk, ready to go work for a geneng biorecovery company in equatorial Africa. All he was hanging around JPL for was to watch Sheena die, and the biosigns in the telemetry indicated that wouldn't be so long now.

Then the Deep s.p.a.ce Network radio telescopes would be turned away from the asteroid for the last time, and whatever followed would unfold in the dark and cold, unheard, and to h.e.l.l with it.

...Here was a new image in his softscreen. A squid, flashing signs at him: Look at me. Dan. Look at me. Dan. Dan. Dan.

He couldn't believe it. "Sheena?"

He had to wait the long seconds while his single word, translated to flashing signs, was transmitted across s.p.a.ce.

Sheena 6.

"...Oh." One of the young.

Dying. Water. Water dying. Fish. Squid. Danger near. Why.

She's talking about the habitat biosphere, he realized. She wants me to tell her how to repair the biosphere. "That's not possible."

Not. Those immense black eyes. Not. Not. Not. The squid flashed through a blizzard of body patterns, bars and stripes pulsing over her hide, her head dipping, her arms raised. I am large and fierce. I am parrotfish, seagra.s.s, rock, coral, sand. I am no squid, no squid, no squid.

He had given Sheena 5 no sign for "liar," but this squid, across millions of miles, bombarding him withlies, was doing its best.

But he was telling the truth.

Wasn't he? How the h.e.l.l could you extend the fixed-duration closed-loop life support system in that ball of water to support more squid, to last much longer, even indefinitely?

...But it needn't stay closed-loop, he realized. The Bootstrap hab was sitting on an asteroid full of raw materials. That had been the point of the mission in the first place.

His brain started to tick at the challenge.

It would be a h.e.l.l of an effort, though. And for what? His NASA pay was going to run out any day, and the soldier boys who had taken back JPL, and wanted to run nothing out of here but low-Earth-orbit milsat missions, would kick his sorry a.s.s out of here sooner than that.

To tell the truth he was looking forward to moving to Africa. He'd live in comfort, in the Brazzaville dome, far from the arenas of the global conflict likely to come; and the work there would be all for the good, as far as he was concerned. None of the ethical ambiguities of Bootstrap.

So why are you hesitating, Ystebo? Are you growing a conscience, at last?

"I'll help you," he said. "What can they do, fire me?"

That wasn't translated.

The squid turned away from the camera.

Dan started to place calls.

Sheena 6 was the smartest of the young.

It was no privilege. There was much work.

She learned to use the glovelike systems that made the firefly robots clamber over the asteroid ground. The mining equipment was adapted to seek out essentials for the phytoplankton, nitrates and phosphates.

Even in the hab itself there was much to do. Dan showed her how to keep the water pure, by pumping it through charcoal filters. But the charcoal had to be replaced by asteroid material, burned in sun fire. And so on.

With time, the hab was stabilized. As long as the machines survived, so would the hab's cargo of life.

But it was too small. It had been built to sustain one squid.

So the firefly robots took apart the rocket plant at the pole and began to a.s.semble new engines, new flows of material, sheets of asteroid-material plastic.

Soon there were four habs, linked by tunnels, one for each of Sheena's young, the smart survivors.

The krill and diatoms bred happily. The greater volume required more power, so Sheena extended the sprawling solar cell arrays.

The new habs looked like living things themselves, sp.a.w.ning and breeding.

But already another cephalopod generation was coming: sacs of eggs clung to asteroid rock, in all the habs.

It wouldn't stop, Sheena 6 saw, more generations of young and more habs, until the asteroid was full, used up. What then? Would they turn on each other at last?

But Sheena 6 was already aging. Such questions could wait for another generation.

In the midst of this activity, Sheena 5 grew weaker. Her young gathered around her.

Look at me, she said. Court me. Love me.

Last confused words, picked out in blurred signs on a mottled carapace, stiff attempts at posture by muscles leached of strength.

Sheena 6 hovered close to her mother. What had those darkening eyes seen? Was it really true that Sheena 5 had been hatched in an ocean without limits, an ocean where hundreds-thousands, millions-of squid hunted and fought, bred and died?

Sheena 5 drifted, purposeless, and the soft gravity of Reinmuth started to drag her down for the last time.

Sheena's young fell on her, their beaks tearing into her cooling, sour flesh.
