Year's Best Scifi 2 Part 8

"Data desks can be lost, or wiped, or their contents amended."

Lvov wished she could see Cobh's face. "Why would we do such a thing?"

"Think it through. Once Earth hears about this, these flake-spiders of yours will be protected. Won't they?"

"Of course. What's bad about that?"

"It's bad for us, Lvov. You've seen what a mess the Poole people made of Charon. If this system is inhabited, a fast GUTs.h.i.+p won't be allowed to come for us. It wouldn't be allowed to refuel here. Not if it meant further damage to the native life forms."

Lvov shrugged. "So we'd have to wait for a slower s.h.i.+p. A liner; one that won't need to take on more reaction ma.s.s here."

Cobh laughed at her. "You don't know much about the economics of GUTs.h.i.+p transport, do you? Now that the System is crisscrossed by Poole wormholes, how many liners like that do you think are still running? I've already checked the manifests. There are two liners capable of a round trip to Pluto still in service. One is in dry dock; the other is heading for Saturn-"

"On the other side of the System."

"Right. There's no way either of those s.h.i.+ps could reach us for, I'd say, a year."

We only have a month's supplies. A bubble of panic gathered in Lvov's stomach."Do you get it bet?" Cobh said heavily. "We'll be sacrificed, if there's a chance that our rescue would damage tke new ecology, here."

"No. It wouldn't happen like that."

Cobh shrugged. "There are precedents."

She was right, Lvov knew. There were precedents, of new forms of life discovered in corners of the system: from Mercury to the remote Kuiper objects. In every case the territory had been ring-fenced, the local conditions preserved, once life-or even a plausible candidate for life-was recognized.

Cobh said, "Pan-genetic diversity. Pan-environmental management. That's the key to it; the public policy of preserving all the species and habitats of Sol, into the indefinite future. The lives of two humans won't matter a d.a.m.n against that."

"What are you suggesting?"

"That we don't tell the Inner System about the flakes."

Lvov tried to recapture her mood of a few days before: when Pluto hadn't mattered to her, when the crash had been just an inconvenience. Now, suddenly, we're talking about threats to our lives, the destruction of an ecology.

What a dilemma. If I don't tell of the flakes, their ecology may be destroyed during our rescue. But if I do tell, the GUTs.h.i.+p won't come for me, and I'll lose my life.

Cobh seemed to be waiting for an answer.

Lvov thought of how Sol light looked over Pluto's ice fields, at dawn.

She decided to stall. "We'll say nothing. For now. But I don't accept either of your options."

Cobh laughed. "What else is there? The wormhole is destroyed; even this flitter is disabled."

"We have time. Days, before the GUTs.h.i.+p is due to be launched. Let's search for another solution. A win-win."

Cobh shrugged. She looked suspicious.

She's right to be, Lvov thought, exploring her own decision with surprise. I've every intention of telling the truth later, of diverting the GUTs.h.i.+p, if I have to.

I may give up my life for this world.

I think.

In the days that followed, Cobh tinkered with the GUTdrive, and flew up to the Interface to gather more data on the Alcubierre phenomenon.

Lvov roamed the surface of Pluto, with her desk set to full record. She came to love the wreaths of cirrus clouds, the huge, misty moon, the slow, oceanic pulse of the centuries-long year.

Everywhere she found the inert bodies of snowflakes, or evidence of their presence: eggs, lidded burrows. She found no other life forms-or, more likely, she told herself, she wasn't equipped to recognize any others.She was drawn back to Christy, the sub-Charon point, where the topography was at its most complex and interesting, and where the greatest density of flakes was to be found. It was as if, she thought, the flakes had gathered here, yearning for the huge, inaccessible moon above them. But what could the flakes possible want of Charon? What did it mean for them?

Lvov encountered Cobh at the crash scar, recharging her suit's systems from the life support packs.

Cobh seemed quiet. She kept her face, hooded by her faceplate, turned from Lvov. Lvov watched her for a while. "You're being evasive," she said eventually. "Something's changed-something you're not telling met about."

Cobh made to turn away, but Lvov grabbed her army "I think you've found a third option. Haven't you?

You've found some other way to resolve this situation, without destroying either us or the flakes."

Cobh shook off her hand. "Yes. Yes, I think I know a way. But-"

"But what?"

"It's dangerous, d.a.m.n it. Maybe unworkable. Lethal." Cobh's hands pulled at each other.

She's scared, Lvov saw. She stepped back from Cobh. Without giving herself time to think about it, she said, "Our deal's off. I'm going to tell the Inner System about the flakes. Right now. So we're going to have to go with your new idea, dangerous or not."

Cobh studied her face; Cobh seemed to be weighing up Lvov's determination, perhaps even her physical strength. Lvov felt as if she were a data desk being downloaded. The moment stretched, and Lvov felt her breath tighten in her chest. Would she be able to defend herself, physically, if it came to that? And was her own will really so strong?

I have changed, she thought. Pluto has changed me.

At last Cobh looked away. "Send your d.a.m.n message," she said.

Before Cobh-or Lvov herself-had a chance to waver, Lvov picked up her desk and sent a message to the inner worlds. She downloaded all the data she had on the flakes: text, images, a.n.a.lyses, her own observations and hypotheses.

"It's done," she said at last.

"And the GUTs.h.i.+p?"

"I'm sure they'll cancel it." Lvov smiled. "I'm also sure they won't tell us they've done so."

"So we're left with no choice," Cobh said angrily. "Look, I know it's the right thing to do. To preserve the flakes. I just don't want to die, that's all. I hope you're right, Lvov."

"You haven't told me how we're going to get home."

Cobh grinned through her faceplate. "Surfing."

"All right. You're doing fine. Now let go of the scooter."

Lvov took a deep breath, and kicked the scooter away with both legs; the little device tumbled away, catching the deep light of Sol, and Lvov rolled in reaction.

Cobh reached out and steadied her. "You can't fall," Cobh said. "You're in orbit. You understand that,don't you?"

"Of course I do," Lvov grumbled.

The two of them drifted in s.p.a.ce, close to the defunct Poole wormhole Interface. The Interface itself was a tetrahedron of electric blue struts, enclosing darkness, its size overwhelming; Lvov felt as if she were floating beside the carca.s.s of some huge, wrecked building.

Pluto and Charon hovered before her like balloons, their surfaces mottled and complex, their forms visibly distorted from the spherical. Their separation was only fourteen of Pluto's diameters. The worlds were strikingly different in hue, with Pluto a blood red, Charon ice blue. That's the difference in surface composition, Lvov thought absently. All that water ice on Charon's surface.

The panorama was stunningly beautiful. Lvov had a sudden, gut-level intuition of the rightness of the various System authorities' rigid pan-environment policies.

Cobh had strapped her data desk to her chest; now she checked the time. "Any moment now. Lvov, you'll be fine. Remember, you'll feel no acceleration, no matter how fast we travel. At the centre of an Alcubierre wave, s.p.a.cetime is locally flat; you'll still be in free fall. There will be tidal forces, but they will remain small. Just keep your breathing even, and-"

"Shut up, Cobh," Lvov said tightly. "I know all this."

Cobh's desk flared with light. "There," she breathed. "The GUTdrive has fired. Just a few seconds, now."

A spark of light arced up from Pluto's surface and tracked, in complete silence, under the belly of the parent world. It was the flitter's GUTdrive, salvaged and stabilized by Cobh. The flame was brighter than Sol; Lvov saw its light reflected in Pluto, as if the surface was a great, fractured mirror of ice. Where the flame pa.s.sed, tongues of nitrogen gas billowed up.

The GUTdrive pa.s.sed over Christy. Lvov had left her desk there to monitor the flakes, and the image the desk transmitted, displayed in the corner of her faceplate, showed a spark crossing the sky.

Then the GUTdrive veered sharply upward, climbing directly toward Lvov and Cobh at the Interface.

"Cobh, are you sure this is going to work?"

Lvov could hear Cobh's breath rasp, shallow. "Look, Lvov, I know you're scared, but pestering me with dumb-a.s.s questions isn't going to help. Once the drive enters the Interface, it will take only seconds for the instability to set in. Seconds, and then we'll be home. In the Inner System, at any rate. Or..."

"Or what?"

Cobh didn't reply.

Or not, Lvov finished for her. If Cobh has designed this new instability right, the Alcubierre wave will carry us home. If not- The GUTdrive flame approached, becoming dazzling. Lvov tried to regulate her breathing, to keep her limbs hanging loose- "Lethe," Cobh whispered.

"What?" Lvov demanded, alarmed."Take a look at Pluto. At Christy."

Lvov looked into her faceplate.

Where the warmth and light of the GUTdrive had pa.s.sed, Christy was a ferment. Nitrogen billowed.

And, amid the pale fountains, burrows were opening. Lids folded back. Eggs cracked. Infant flakes soared and sailed, with webs and nets of their silk-a.n.a.logue hauling at the rising air.

Lvov caught glimpses of threads, long, sparkling, trailing down to Pluto-and up toward Charon.

Already, Lvov saw, some of the baby flakes had hurtled more than a planetary diameter from the surface, toward the moon.

"It's goose summer," she said.

"What?"

"When I was a kid... the young spiders spin bits of webs, and climb to the top of gra.s.s stalks, and float off on the breeze. Goose summer-'gossamer.'

"Right," Cobh said skeptically. "Well, it looks as if they are making for Charon. They use the evaporation of the atmosphere for lift... Perhaps they follow last year's threads, to the moon. They must fly off every perihelion, rebuilding their web bridge every time. They think the perihelion is here now. The warmth of the drive-it's remarkable. But why go to Charon?"

Lvov couldn't take her eyes off the flakes. "Because of the water," she said. It all seemed to make sense, now that she saw the flakes in action. "There must be water gla.s.s on Charon's surface. The baby flakes use it to build their bodies. They take other nutrients from Pluto's interior, and the gla.s.s from Charon...

They need the resources of both worlds to survive-"

"Lvov!"

The GUTdrive flared past them, sudden, dazzling, land plunged into the damaged Interface.

Electric-blue light exploded from the Interface, was.h.i.+ng over her.

There was a ball of light, unearthly, behind her, and an irregular patch of darkness ahead, like a rip in s.p.a.ce. Tidal forces plucked gently at her belly and limbs.

Pluto, Charon, and goose summer disappeared. But the stars, the eternal stars, shone down on her, just as they had during her childhood on Earth. She stared at the stars, trusting, and felt no fear.

Remotely, she heard Cobh whoop, exhilarated.

The tides faded. The darkness before her healed, to reveal the brilliance and warmth of Sol.

Greg Benford is the author of the cla.s.sic SF novel Timescape, as well as a number of other highly regarded works including In the Ocean of Night and Sailing Bright Eternity. He is the finest writer of hard SF from the generation after Larry Niven, and writes, primarily in the tradition of Arthur C. Clarke, of immense, fertile, awesome astronomical vistas and technological marvels, but with a depth andrichness of characterization not achieved by many other SF writers.

"A Worm in the Well" is not typical of his fiction in that it is more in the hard SF problem-solving tradition of Robert A. Heinlein and Paul Anderson than Arthur C. Clarke. Here we have an elegant adventure from a.n.a.log, the magazine that upholds the traditions of hard SF.

A Worm in the Well

by Gregory Benford

She was about to get baked, and all because she wouldn't freeze a man.

"Optical," Claire called. Erma obliged.

The Sun spread around them, a bubbling plain. She had notched the air conditioning cooler but it didn't help much.

Geysers burst in gaudy reds and actinic violets from the yellow-white froth. The solar coronal arch was just peeking over the horizon, like a wedding ring stuck halfway into boiling white mud. A monster, over two thousand kilometers long, sleek and slender and angry crimson.

She turned down the cabin lights. Somewhere she had read that people felt cooler in the dark. The temperature in here was normal but she had started sweating.
