Space Stations Part 28

Not so on Luna.

You had judged the streams of newborn air rightly. Thicker airs than Earth's took longer to exhaust, and so did not fall until they reached the poles. Thus the new world had no chains of deserts, and one simple circulating air cell ground away in each hemisphere. Moisture worked its magics.

You smiled to see your labors come right. Though anch.o.r.ed in your mammoth Station, you felt the firstpinp.r.i.c.ks of awareness in the crawlers, flyers, and diggers who probed the freshening Moon.

You tasted their flavors, the br.i.m.m.i.n.g possibilities. Northerly winds swept the upper half of the globe, bearing poleward, then swerving toward the west to make the occasional mild tornado. (Not all weather should be boring.) Clouds patrolled the air, still fretting over their uneasy births. Day and night came in their slow rhythm, stirring the biological lab that worked below. You sometimes took a moment from running all this, just to watch.

Lunascapes. Great Grayworld.

Where day yielded to dark, valleys sank into smoldering blackness. Already a chain of snowy peaks shone where they caught the sun's dimming rays, and lit the plains with slanting colors like live coals. Sharp mountains cleaved the cloud banks, leaving a wake like that of a huge s.h.i.+p. At the fat equator, straining still to adjust to the new spin, tropical thunderheads glowered, lit by orange lightning that seemed to be looking for a way to spark life among the drifting molecules.

All that you did, in a mere decade. You had made "the lesser light that rules the night" now s.h.i.+ne five times brighter, casting sharp shadows on Earth. Sun rays glinted by day from the young oceans, dazzling the eyes on Earth. And the mother world itself reflected in those muddy seas, so that when thealignment was right, people on Earth's night side gazed up into their own mirrored selves. Viewed at just the right angle, Earth's image was rimmed with ruddy sunlight, refracting through Earth's air.

You knew it could not last, but were pleased to find the new air stick around. It would bleed away in ten thousand years, but by that time other measures could come into play. You had plans for a monolayer membrane to cap your work, resting atop the whole atmosphere, the largest balloon ever conceived.

Later? No, act in the moment-and so you did.

You wove it with membrane skill, cast it wide, let it fall-to rest easy on the thick airs below. Great holes in it let s.h.i.+ps glide through, but the losses from those would be trivial.

Not that all was perfect. Luna had no soil, only the damaged dust left from four billion years beneath the solar wind's anvil.

After a mere momentary decade (nothing, to you), fresh wonders bloomed.

Making soil from gritty grime was work best left to the micro-beasts who loved such stuff. To do great works on a global scale took tiny a.s.sistants. You fas.h.i.+oned them in your own labs, which poked outward from the Station's many-armed skin.

Gray grew a crust. Earth is in essence a tissue of microbial organisms living off the sun's fires. Gray would do the same, in fast-forward. You cooked upnot mere primordial broths, but endless chains of regulatory messages, intricate feedback loops, organic gavottes.

Earth hung above, an example of life ornamented by eleborate decorations, structures of forest and gra.s.s and skin and blood-living quarters, like seagra.s.s and zebras and eucalyptus and primates.

Do the same, you told yourself. Only better.

These tasks you loved. Their conjuring consumed more decades, stacked end on end. You were sucked into the romance of tiny turf wars, chemical a.s.saults, microbial murders, and invasive incests. But you had to play upon the stellar stage, as well.

You had not thought about the tides. Even you had not found a way around those outcomes of gravity's gradient. Earth raised bulges in Gray's seas a full twenty meters tall. That made for a dim future for coastal property, even once the air became breathable.

Luckily, even such colossal tides were not a great bother to the lakes you shaped in crater beds. These you made as breeding farms for the bioengineered minions who ceaselessly tilled the dirts, ma.s.saged the gases, filtered the tinkling streams that cut swift ways through beds of volcanic rock.

Indeed, here and there you even found a use for the tides. There were more watts lurking there, in kinetic energy. You fas.h.i.+oned push-plates to tap some of it, to run your substations. Thrifty G.o.ds donot have to suck up to (and from) Earthside.

And so the sphere that, when you began, had been the realm of strip miners amid ma.s.s-driver camps, of rugged, suited loners... became a place where, someday, humans might walk and breathe free.

That time is about to come. You yearn for it. For you, too, can then manifest yourself, your Station, as a mere mortal... and set foot upon a world that you would name Selene.

You were both Station and more, by then. How much more few knew. But some sliver of you clung to the name of Benjan- Benjan nodded slightly, ears ringing for some reason.

The smooth, sure interviewer gave a short introduction, portentous and grim-typical Earther.

"Man... or manifestation? This we must all wonder as we greet an embodiment of humanity's greatest-and now ancient-construction project.

One you and I can see every evening in the sky-for those who are still surface dwellers."

3-D cameras moved in smooth arcs through the studio darkness beyond. The two men sat in a pool of light. The interviewer spoke toward the directional mike as he gave the background on Benjan's charges against the Council.

Smiles galore. Plat.i.tudes aplenty. That done, came the attack.

"But isn't this a rather abstract, distant point tobring at this time?" the man said, turning to Benjan.

Benjan blinked, uncertain, edgy. He was a private man, used to working alone. Now that he was moving against the Council, he had to bear these public appearances, these... manifestations... of a dwindled self. "To, ah, the people of the next generation, Gray will not be an abstraction-"

"You mean the Moon?"

"Uh, yes, Gray is my name for it. That's the way it looked when I-uh, we all-started work on it centuries ago."

"Yet you were there all along, in fact."

"Well, yes. But when I'm-we're-done." Benjan leaned forward, and his interviewer leaned back, as if not wanting to be too close. "it will be a real place, not just an idea-where you all can live and start a planned ecology. It will be a frontier."

"We understand that romantic tradition, but-"

"No, you don't. Gray isn't just an idea, it's something I've-we've-worked on for everyone, whatever shape or genetype they might favor."

"Yes, yes, and such ideas are touching in their, well, customary way, but-"

"But the only ones who will ever enjoy it, if the Council gets away with this, is the Majiken Clan."

The interviewer pursed his lips. Or was this a he at all? In the current style, the bulging muscles and thick neck might just be fas.h.i.+on statements. "Well, the Majiken are a very large, important segment ofthe-"

"No more important than the rest of humanity, in my estimation."

"But to cause this much stir over a world which will not even be habitable for at least decades more-"

"We of the Station are there now."

"You've been modified, adapted."

"Well, yes. I couldn't do this interview on Earth.

I'm grav-adapted."

"Frankly, that's why many feel that we need to put Earth-side people on the ground on Luna as soon as possible. To represent our point of view."

"Look, Gray's not just any world. Not just a gas giant, useful for raw gas and nothing else. Not a Mercury type; there are millions of those littered out among the stars. Gray is going to be fully Earthlike.

The astronomers tell us there are only four semiterrestrials outside the home system that humans can ever live on, around other stars, and those are pretty terrible. I-"

"You forget the Outer Colonies," the interviewer broke in smoothly, smiling at the 3-D.

"Yeah-ice b.a.l.l.s." He could not hide his contempt. What he wanted to say, but knew it was terribly old-fas.h.i.+oned, was: d.a.m.n it, Gray is happening now, we've got to plan for it.

Photosynthesis is going on. I've seen it myself-h.e.l.l, I caused it myself-carbon dioxide and water convertinginto organics and oxygen, gases fresh as a breeze.

Currents carry the algae down through the cloud layers into the warm areas, where they work just fine.

That gives off simple carbon compounds, raw carbon and water. This keeps the water content of the atmosphere constant, but converts carbon dioxide- we've got too much right now-into carbon and oxygen. It's going well, the rate itself is exponentiating -.

Benjan shook his fist, just now realizing that he was saying all this out loud, after all. Probably not a smart move, but he couldn't stop himself. "Look, there's enough water in Gray's deep rock to make an ocean a meter deep all the way around the planet.

That's enough to resupply the atmospheric loss, easy, even without breaking up the rocks. Our designer plants are doing their jobs."

"We have heard of these routine miracles-"

"-and there can be belts of jungle-soon! We've got mountains for climbing, rivers that snake, polar caps, programmed animals coming up, beautiful sunsets, soft summer storms-anything the human race wants. That's the vision we had when we started Gray. And I'm d.a.m.ned if I'm going to let the Majiken-"

"But the Majiken can defend Gray," the interviewer said mildly.

Benjan paused. "Oh, you mean-"

"Yes, the ever-hungry Outer Colonies. Surely ifGray proves as extraordinary as you think, the rebellious colonies will attempt to take it." The man gave Benjan a broad, insincere smile. Dummy, it said. Don't know the real-politics of this time, do you?

He could see the logic. Earth had gotten soft, fed by a tougher empire that now stretched to the chilly preserve beyond Pluto. To keep their manicured lands clean and "original" Earthers had burrowed underground, built deep cities there, and sent most manufacturing off-world. The real economic muscle now lay in the hands of their suppliers of fine rocks and volatiles, s.h.i.+pped on long orbits from the Outers and the Belt. These realities were hard to remember when your attention was focused on the details of making a fresh world. One forgot that appet.i.tes ruled, not reason.

Benjan grimaced. "The Majiken fight well, they are the backbone of the Fleet, yes. Still, to give them a world-"

"Surely in time there will be others," the man said reasonably.

"Oh? Why should there be? We can't possibly make Venus work, and Mars will take thousands of years more-"

"No, I meant built worlds-stations."

He snorted. "Live inside a can?"

"That's what you do," the man shot back.

"I'm... different."

"Ah yes." The interviewer bore in, lips compressedto a white line, and the 3-Ds followed him, snouts peering. Benjan felt hopelessly outmatched. "And just how so?"

"I'm... a man chosen to represent..."

"The Shaping Station, correct?"

"I'm of the breed who have always lived in and for the Station."

"Now, that's what I'm sure our audience really wants to get into. After all, the Moon won't be ready for a long time. But you-an ancient artifact, practically-are more interesting."

"I don't want to talk about that." Stony, frozen.

"Why not." Not really a question.

"It's personal."

"You're here as a public figure!"

"Only because you require it. n.o.body wants to talk to the Station directly."

"We do not converse with such strange machines."

"It's not just a machine."

"Then what is it?"

"An... idea," he finished lamely. "An... ancient one." How to tell them? Suddenly, he longed to be back doing a solid, worthy job-flying a jet in Gray's skies, pus.h.i.+ng along the organic chemistry- The interviewer looked uneasy. "Well, since you won't go there... Our time's almost up and-"

Again, I am falling over Gray.

Misty auburn clouds, so thin they might be only illusion, spread below the s.h.i.+p. They caught red asdusk fell. The thick air refracted six times more than Earth's, so sunsets had a slow-motion grandeur, the full pallet of pinks and crimsons and rouge-reds.

I am in a ramjet-the throttled growl is unmistakable- lancing cleanly into the upper atmosphere. Straps tug and pinch me as the craft banks and sweeps, the smoothly wrenching way I like it, the stubby snout sipping precisely enough for the air's growing oxygen fraction to keep the engine thrusting forward.

I probably should not have come on this flight; it is an uncharacteristic self-indulgence. But I could not sit forever in the Station to plot and plan and calculate and check. I had to see my handiwork, get the feel of it. To use my body in the way it longed for.

I make the ramjet arc toward Gray's night side.

The horizon curves away, clean hard blue-white, and-chung!-I take a jolt as the first canister blows off the underbelly below my feet. Through a rearview camera I watch it tumble away into ruddy oblivion. The canister carries more organic cultures, a new matrix I selected carefully back on Station, in my expanded mode. I watch the s.h.i.+ny morsel explode below, yellow flash. It showers intricate, tailored algae through the clouds.

Gray is at a crucial stage. Since the centuries-ago slamming by the air-giving comets, the conspiracy of spin, water, and heat (great gifts of astro-engineering) had done their deep work.

Volcanoes now simmered, percolating more moisturefrom deep within, kindling, kindling. Some heat climbed to the high cloud decks and froze into thin crystals.

There, I conjure fresh life-tinkering endlessly.

Life, yes. Carefully engineered cells, to breathe carbon dioxide and live off the traces of other gases this high from the surface. In time. Photosynthesis in the buoyant forms- gas-bag trees, spindly but graceful in the top layer of Gray's dense air-conjure carbon dioxide into oxygen.

I glance up, encased in the tight flight jacket, yet feeling utterly free, naked. Incoming meteors. Brown clouds of dust I had summoned to orbit about Gray were cutting off some sunlight.

Added spice, these-ingredients sent from the asteroids to pepper the soil, p.r.i.c.k the air, speed chemical matters along. The surface was cooling, the Gray greenhouse winding down. Losing the heat from the atmosphere's birth took centuries. Patience, prudence.

Now chemical concerts in the rocks slowed. I felt those, too, as a distant sampler hailed me with its accountant's chattering details. Part of the song.

Other chem ch.o.r.es, more subtle, would soon become energetically possible. Fluids could seep and run. In the clotted air below, crystals and cells would make their slow work. All in time...

In time, the first puddle had become a lake. How I had rejoiced then!What joy, to fertilize those still waters with minutely programmed bacteria, stir and season their primordial soup- and wait.

What sweet mother Earth did in a billion years I did to Gray in fifty. Joyfully! Singing the song of the molecules, in concert with them.

My steps were many, the methods subtle. To shape the mountain ranges I needed further infalls from small asteroids, taking a century-ferrying rough-cut stone to polish a jewel-world. Many died, of course, caught in the great grinding gears that bored 'roids, made the rock-flinging tunnels, did the hard brute labors in cold and vacuum.

Memories... of a man, and more. Fas.h.i.+oned from the tick of time, ironed out by the swift pa.s.sage of mere puny years, of decades, of the ringing centuries. Worlds take time.
