Green mars (8 page)

They laid out the new dome in a new pattern, with the village away from the tunnel lock, near an escape tunnel that ran far under the ice, to an exit in upper Chasma Australe. The greenhouses were set nearer the perimeter lights, and the dune crests were higher than before, and the weather equipment was set right next to the Rickover. There were any number of small improvements of that sort, which kept it from being a replica of their old home. And every day they were so busy with the work of constructing it that there was no time to think much about the change; morning classes in the schoolhouse had been canceled since the fall, and now the kids were merely a rotating work crew, assigned to whoever needed help the most on that particular day. Sometimes the adult overseeing them would try to make their work into a lesson—Hiroko and Nadia were especially good at this—but they had little time to spare, and only added an explanatory sentence to instructions that were too simple to need explanation in any case: tightening wall modules with Alien wrenches, carrying around planters and algae jars in the greenhouses, and so on. It was just work—they were part of the workforce, which was too small for the task even so, despite the versatile robots that looked like rovers stripped of their exteriors. And running around, doing the work, Nirgal was for the most part happy.

But once as he left the schoolhouse and saw the dining hall, rather than the big shoots of Creche Crescent, the sight brought him up short. His old familiar world was gone, gone forever. That was how time worked. It sent a pang through him that brought tears to his eyes, and he spent the rest of that day somewhat stunned and distant, as if always a step or two behind himself, watching everything that happened drained of emotion, detached as he had been after Simon’s death, exiled to the white world one step outside the green. There was nothing to indicate that he would ever come out of such a melancholy state, and how could he know if he ever would? All those days of his childhood were gone, along with Zygote itself, and they would never come back, and this day too would pass and disappear, this dome too slowly sublime away and crash in on itself. Nothing would last. So what was the point? For hours at a time this question plagued him, taking the taste and color out of everything, and when Hiroko noticed how subdued he was, and inquired what was wrong, he simply asked her outright. There was that advantage to Hiroko; you could ask her anything, including the fundamental questions. “Why do we do all this, Hiroko? When it all goes white no matter what?”

She stared at him, birdlike, her head cocked to one side. He thought he could see her affection for him in that cock of the head, but he wasn’t sure; as he got older he felt he understood her (along with everyone else) less and less.

She said, “It is sad the old dome is gone, isn’t it. But we must focus on what is coming. This too is viriditas. To concentrate not on what we have created, but what we will create. The dome was like a flower which wilts and falls, but contains the seed of a new plant, which grows and then there are new flowers and new seeds. The past is gone. Thinking about it will only make you melancholy. Why, I was a girl in Japan once, on Hokkaido Island! Yes, as young as you! And I can’t tell you how far gone that is. But here we are now, you and me, surrounded by these plants and these people, and if you pay attention to them, and how you can make them increase and prosper, then the life comes back into things. You feel the kami inside all things, and that is all you need. This moment itself is all we ever live in.”

“And the old days?”

She laughed at that. “You’re growing up. Well, you must remember the old days from time to time. They were good ones, weren’t they? You had a happy childhood; that is a blessing. But so will these days be good. Take this moment right here, and ask yourself, What now is lacking? Hmmm? ... Coyote says that he wants you and Peter to go along with him on another trip. Maybe you should go and get out under the sky again, what do you say?”

So preparations for another trip with Coyote were made, and they continued to work on the new Zygote, informally rechristened Gamete. At night in the relocated dining hall the adults talked for a long time about their situation. Sax and Vlad and Ursula, among others, wanted back into the surface world. They couldn’t do their real work properly in the hidden sanctuaries; they wanted back into the full flood of medical science, terraforming, construction. “We’ll never be able to disguise ourselves,” Hiroko said. “No one can change their genomes.”

“It’s not our genomes we should change, but the records,” Sax said. “That’s what Spencer has done. He’s gotten his physical characteristics into a new record identity.”

“And we did cosmetic surgery on his face,” Vlad said.

“Yes, but it was minimal because of our age, right? We none of us look the same. Anyway, if you do something like what he did, we could take on new identities.”

Maya said, “Did Spencer really get into all the records?”

Sax shrugged. “He was left behind in Cairo, and had the chance to get into some of the ones being used now for security purposes. That has been enough. I’d like to try something similar. Let’s see what Coyote says about it. He’s not in any records at all, so he must know how he did it.”

“He’s been hidden from the beginning,” Hiroko said. “That’s different.”

“Yes, but he might have some ideas.”

“We could just move into the demimonde,” Nadia pointed out, “and stay off the records entirely. I think I’d like to try that.”

Night after night they talked these matters over. “Well, a little change of appearance might be in order. You know Phyllis is back, we have to remember that.”

“I still can’t believe they survived. She must have nine lives.”

“In any case we were on too many news shows. We have to take care.”

By day Gamete was slowly completed. But it never seemed right to Nirgal, no matter how much he tried to focus on the making of it. It wasn’t his place.

News came from another traveler that Coyote would be by soon. Nirgal felt his pulse quicken; to get back under the starry sky again, wandering by night in Coyote’s boulder car, from sanctuary to sanctuary…

Jackie stared at him attentively as he talked about it to her. And that afternoon, after they were dismissed from the day’s work, she led him down to the tall new dunes and kissed him. When he recovered his wits he kissed back, and then they were kissing passionately, hugging each other hard and steaming all over each other’s faces. They knelt in the trough between two high dunes, under a pale thin fog, and then lay together in a cocoon made of their down coats, and kissed and touched each other, peeling down each other’s pants and creating a little envelope of their own warmth, huffing out steam and crackling the frost on the sand underneath their coats. All this without a word, merging in one great hot electric circuit, in defiance of Hiroko and all the world. So this is what it feels like, Nirgal thought. Under the strands of Jackie’s black hair grains of sand gleamed like jewels, as if minute ice flowers were contained within them. Glories inside everything.

When they were done they crawled up to glance over the dune crest, to make sure no one was coming their way, and then returned to their nest and pulled their clothes over them, for the warmth. They huddled together, kissing voluptuously and without haste. And Jackie prodded him in the chest with a finger and said, “Now we belong to each other.”

Nirgal could only nod happily and kiss the long expanse of her throat, his face buried in her black hair. “Now you belong to me,” she said.

He sincerely hoped it was true. It was how he had wanted it, for as long as he could remember.

But that evening in the bathhouse Jackie sloshed across the pool, and caught up Dao and gave him a hug, body to body. She pulled back and stared at Nirgal with a blank expression, her dark eyes like holes in her face. Nirgal sat frozen in the shallows, feeling his torso stiffen as if preparing for a blow. His balls were still sore from coming in her; and there she stood draped against Dao, as she hadn’t been in months, staring at him with a basilisk stare.

The strangest sensation swept over him—he understood that this was a moment he would remember all his life, a pivotal moment, right there in the steamy comfortable bath, under the osprey eye of the statuesque Maya, whom Jackie hated with a fine hate, who was now watching the three of them closely, suspecting something. So this was how it was. Jackie and Nirgal might belong to each other, and he certainly belonged to her—but her idea of belonging was not his. The shock of this knocked his breath out, it was a kind of collapse of the roof of his understanding of things. He looked at her, stunned, hurt, becoming angry—she hugged Dao all the more—and he understood. She had collected both of them. Yes, it made sense, it was certain; and Reull and Steve and Frantz were all equally devoted to her—perhaps that was just a holdover from her rule over the little band, but perhaps not. Perhaps she had collected all of them. And clearly, now that Nirgal was a kind of foreigner to them, she was more comfortable with Dao. So he was an exile in his own home, and in his own love’s heart. If she had a heart!

He didn’t know if any of these impressions were true, didn’t know how to find out. He wasn’t sure he wanted to find out. He got out of the bath and retreated into the men’s room, feeling Jackie’s gaze boring into his back, and Maya’s too.

In the men’s room he caught sight of an unfamiliar face in one of the mirrors. He stopped short and recognized it as his own face, twisted with distress.

He approached the mirror slowly, feeling the strange sensation of momentousness sweep through him again. He stared at the face in the mirror, stared and stared; it came to him that he was not the center of the universe, or its only consciousness, but a person like all the rest, seen from the outside by others, the way he saw others when he looked at them. And this strange Nirgal-in-the-mirror was an arresting black-haired brown-eyed boy, intense and compelling, a near twin to Jackie, with thick black eyebrows and a… a look. He didn’t want to know any of this. But he felt the power burning at his fingertips, and recalled how people looked at him, and understood that for Jackie he might represent the same sort of dangerous power that she did .for him—which would explain her consorting with Dao, as an attempt to hold him off, to hold a balance, to assert her power. To show they were a matched pair— and a match. And all of a sudden the tension left his torso, and he shuddered, and then grinned, lopsidedly. They did indeed belong to each other. But he was still himself.

So when Coyote showed up and came by to ask Nirgal to join him on another trip, he agreed instantly, very thankful for the opportunity. The flash of anger on Jackie’s face when she heard the news was painful to see; but another part of him exulted at his otherness, at his ability to escape her, or at least to get some distance. Match or not, he needed it.

A few evenings later he and Coyote and Peter and Michel drove away from the huge mass of the polar cap, into the broken land, black under its blanket of stars.

Nirgal looked back at the luminous white cliff with a tumultuous mix of feelings; but chief among them was relief. Back there they would burrow ever deeper under the ice, it seemed, until they lived in a dome under the South Pole—while the red world spun through the cosmos, wild among the stars. Suddenly he understood that he would never again live under the dome, never return to it except for short visits; this was not a matter of choice, but simply the way it was going to happen. His fate, or destiny. He could feel it like a red rock in his hand. Henceforth he would be homeless, unless the whole planet someday became his home, every crater and canyon known to him, every plant, every rock, every person—everything, in the green world and the white. But that (remembering the storm seen from the edge of Promethei Rupes) was a task to occupy many lives. He would have to start learning.

PART 2

---The Ambassador

Asteroids with elliptical orbits that cross inside the orbit of Mars are called Amor asteroids, (if they cross inside the orbit of Earth they are called Trojans.) In 2088 the Amor asteroid known as 2034 B crossed the path of Mars some eighteen million kilometers behind the planet, and a clutch of robotic landing vehicles originating from Luna docked with it shortly thereafter. 2034 B was a rough ball about five kilometers in diameter, with a mass of about fifteen billion tons. As the rockets touched down, the asteroid became New Clarke.

Quickly the change became obvious. Some landers sank to the dusty surface of the asteroid and began drilling, excavating, stamping, sorting, conveying. A nuclear reactor power plant switched on, and fuel rods moved into position. Elsewhere ovens fired, and robot stokers prepared to shovel. On other landers payload bays opened, and robot mechanisms spidered out onto the surface and anchored themselves to the irregular planes of rock. Tunnelers bored in. Dust flew off into the space around the asteroid, and fell back down or escaped forever. Landers extended pipes and tubes into each other. The asteroid’s rock was carbonaceous chrondrite, with a good percentage of water ice shot through it in veins and bubbles. Soon the linked collection of factories in the landers began to produce a variety of carbon-based materials, and some composites.

Heavy water, one part in every 6,000 of the water ice in the asteroid, was separated out. Deuterium was made from the heavy water. Parts were made from the carbon composites, and other parts, brought along in another payload, were brought together with the new ones in factories. New robots appeared, made mostly of Clarke itself. And so the number of machines grew, as computers on the landers directed the creation of an entire industrial complex.

After that the process was quite simple, for many years. The principal factory on New Clarke made a cable of carbon nanotube filaments. The nanotubes were made of carbon atoms linked in chains so that the bonds holding them together were as strong as any that humans could manufacture. The filaments were only a few score meters long, but were bundled in clusters with their ends overlapping, and then the bundles were bundled, until the cable was nine meters in diameter. The factories could create the filaments and bundle them at speeds that allowed them to extrude the cable at a rate of about four hundred meters an hour, ten kilometers a day, for hour after hour, day after day, year after year.

While this thin strand of bundled carbon spun out into space, robots on another facet of the asteroid were constructing a mass driver, an engine that would use the deuterium from the indigenous water to fire crushed rock away from the asteroid at speeds of 200 kilometers a second. Around the asteroid smaller engines and conventional rockets were also being constnicted and stocked with fuels, waiting/or the time when they would fire, and perform the work of attitude jets. Other factories constructed long wheeled vehicles capable of running back and forth on the growing cable, and as the cable continued to appear out of the planet, small rocket jets and other machinery were attached to it.

The mass driver fired. The asteroid began to move into a new orbit.

Years passed. The asteroid’s new orbit intersected the orbit of Mars such that the asteroid came within ten thousand kilometers of Mars, and the collection of rockets on the asteroid fired in a way that allowed the gravity of Mars to capture it, in an orbit at first highly elliptical. The jets continued to fire off and on, regularizing the orbit. The cable continued to extrude. More years passed.

A little over a decade after the landers had first touched down, the cable was approximately thirty thousand kilometers long. The asteroid’s mass was about eight billion tons, the cable’s mass was about seven billion. The asteroid was in an elliptical orbit with a periapsis of around fifty thousand kilometers. But now all the rockets and mass drivers on both New Clarke and the cable itself began to fire, some continuously but most in spurts. One of the most powerful computers ever made sat in one of the payload bays, coordinating the data from sensors and determining what rockets should fire when. The cable, at this time pointing away from Mars, began to swing around toward it, as in the pivoting of some delicate part of a timepiece. The asteroid’s orbit became smaller and more regular.

More rockets landed on New Clarkefor the first time since that first touchdown, and robots in them began the construction of a spaceport. The tip of the cable began to descend toward Mars. Here the calculus employed by the computer soared off into an almost metaphysical complexity, and the gravitational dance of asteroid and cable with the planet became ever more precise, moving to a music that was in a permanent ritard, so that as the great cable grew closer to its proper position, its movements became slower and slower. If anyone had been able to see the full extent of this spectacle, it might have seemed like some spectacular physical demonstration of Zeno’s paradox, in which the racer gets closer to the finish line by halving distances ... But no one ever saw the full spectacle, for no witnesses had the senses necessary. Proportionally the cable was far thinner than a human hair—if it had been reduced to a hair’s diameter, it would still have been hundreds of kilometers long—and so it was only visible for short portions of its entire length. Perhaps one might say that the computer guiding it in had the fullest sensation of it. For observers down on the surface of Mars, in the town of Sheffield, on the volcano Pavonis Mons (Peacock Mountain), the cable made its first appearance as a very small rocket, descending with a very thin leader line attached to it; something like a bright lure and a thin fishing line, being trolled by some gods in the next universe up. From this ocean-bottom perspective the cable itself followed its leader line down into the massive concrete bunker east of Sheffield with an aching slowness, until most humans simply stopped paying attention to the vertical black stroke in the upper atmosphere.

But the day came when the bottom of the cable, firing jets to hold its position in the gusty winds, dropped down into the hole in the roof of the concrete bunker, and settled into its collar. Now the cable below the areosynchronous point was being pulled down by Mars’s gravity; the part above the areosynchronous point was trying to follow New Clarke in centrifugal flight away from the planet; and the carbon filaments of the cable held the tension, and the whole apparatus rotated at the same speed as the planet, standing above Pavonis Mons in an oscillating vibration that allowed it to dodge Deimos; all of it controlled still by the computer on New Clarke, and the long battery of rockets deployed on the carbon strand.

The elevator was back. Cars were lifted up one side of the cable from Pavonis, and other cars were let down from New Clarke, providing a counterweight so that the energy needed for both operations was greatly lessened. Spaceships made their approach to the New Clarke spaceport, and when they left they were given a slingshot departure. Mars’s gravity well was therefore substantially mitigated, and all its human intercourse with Earth and the rest of the solar system made less expensive. It was as if an umbilical cord had been retied.
