Green Mars

by Kim Stanley Robinson

  She put her bag on the bed and went back out, down to the market to buy dinner. She bought from vendors with carts and umbrellas, and sat on a bench placed on the grass bordering the corniche, eating souvlakia and drinking from a little bottle of retsina, watching the evening crowd make their leisurely promenade up and down the corniche. The closest edge of the ice sea looked to be about forty kilometers away, and now all but the easternmost part of the ice was in the shadow of the Hellespontus, a dusky blue shading in the east to alpenglow pink.

  Spencer sat down beside her on the bench. “Nice view,” he remarked.

  She nodded and continued eating. She offered him the bottle of retsina, and he said, “No thank you,” holding up a half-eaten tamale. She nodded and swallowed.

  “What are you working on?” she asked when she was done.

  “Parts for Sax. Bioceramics, among other things.”

  “For Biotique?”

  “For a sister company. She Makes Seashells.”

  “What?”

  “It’s the name of the company. Another Praxis division.”

  “Speaking of Praxis . . .” She glanced at him.

  “Yes. Sax wants these parts pretty bad.”

  “For weapons?”

  “Yes.”

  She shook her head. “Can you keep him on a leash for a while?”

  “I can try.”

  They watched the sunlight drain out of the sky, flowing westward like a liquid. Behind them lights flicked on in the trees over the market, and the air began to chill. Maya felt grateful that there was an old friend sitting beside her, in comfortable silence. Spencer’s behavior toward her made a telling contrast to Sax; in his friendliness was his apology for his recriminations in the car after Kasei Vallis, and his forgiveness for what she had done to Phyllis. She appreciated it. And in any case he was one of the primal family, and it was nice to have that during yet another move. A new start, a new city, a new life—how many was it now?

  “Did you know Frank very well?” she said.

  “Not really. Not like you and John knew him.”

  “Do you think . . . do you think he could have been involved in John’s murder?”

  Spencer continued to look out at the blue ice on the black horizon. Finally he took the retsina bottle from the bench beside her, drank. He looked at her. “Does it matter anymore?”

  She had spent many of the early years working in the Hellas Basin, convinced as she had been that its low elevation was going to make it an obvious site for settlement. Now the land just above the—1-kilometer contour was being settled in places all around the basin, places she had been among the first to explore. She had her old notes on them in her AI, and now, as Ludmilla Novosibirskaya, she got to put them to use.

  Her job was in the administration of the hydrological company that was flooding the basin. The team was part of a conglomerate of organizations developing the basin, among them the Black Sea Economic Group’s oil companies, the Russian company that had tried to resuscitate the Caspian and Aral seas, and her company, Deep Waters, which was Praxis-owned. Maya’s job involved coordinating the many hydrological operations in the region, so again she got to see the heart of the Hellas project, just as in the old days when she had been the driving force behind the entire thing. This was satisfying in various ways, some of them strange—for instance her town Low Point (a mistaken siting, she had-to admit) was out there getting drowned deeper every day. That was fine: drown the past, drown the past, drown the past. . . .

  So she had her work, and her apartment, which she filled with used furniture and hanging kitchen implements and potted plants. And Odessa proved to be a pleasant town. It was built principally of yellow stone and brown tile, and placed on a part of the slope of the basin rim that curved inward more than usual, so that every part of town looked down on the center of the dry waterfront, and every part had a great view over the basin to the south. The lower districts were devoted to shops and business and parks, the higher ones to residential neighborhoods and garden strips. The town lay just above 30° latitude in the south, and so she had gone from autumn to spring, with the big hot sun shining down the stepped streets of the upper town, and melting away the winter’s snow from the ice mass’s edge, and the peaks of the Hellespontus Mountains on their western horizon. A handsome little town.

  And about a month after her arrival, Michel came down from Sabishii, and took over the apartment right next door to hers. At her suggestion he installed a connecting door between their two living rooms, and after that they wandered between the two apartments as if in one, living their lives in a conjugal domesticity which Maya had never experienced before, a normality that she found very restful. She did not love Michel passionately, but he was a good friend, a good lover, and a good therapist, and having him around was like having an anchor inside her, keeping her from flying away into exhilarations of hydrology or revolutionary fervor, also from sinking too deep into terrible abysses of political despair or personal repugnance. Cycling up and down the sine wave of her moods was a helpless oscillation that she hated, and anything Michel did in the way of amplitude modulation she appreciated. They kept no mirrors in the apartments, which along with clomipramine helped to dampen the cycle. But the bottoms of pots, and the windows at night, gave her the bad news if she cared to have it. As often enough she did.

  With Spencer down the hall, the building had just the slightest feeling of Underhill to it, reinforced occasionally by visitors from out of town, using their apartment in its capacity as safe house. When others of the First Hundred came through, they would go out and walk the waterless waterfront, looking at the ice horizon and exchanging the news like old folks anywhere. Marsfirst, led by Kasei and Dao, was becoming more and more radical. Peter was working on the elevator, drawn like a moth back to its moon. Sax had stopped his mad ecotage campaign for the time being, thank God, and was concentrating on his industrial effort in Vishniac mohole, building surface-to-space missiles and the like. Maya shook her head at this news. It was not military might that would do it for them; on that issue she sided with Nadia and Nirgal and Art. They would need something else, something she could not yet visualize. And this gap in her thinking was one of the things that would start her downward in the sine wave of her moods, one of the things that made her mad.

  Her work coordinating the various aspects of the flooding project began to get interesting. She trammed or walked down to the offices in the center of town, and there worked hard to process all the reports sent in by the many dowsing crews and drilling operations—all full of glowing estimates of the amounts of water they might put into the basin, and all accompanied by requests for more equipment and personnel, until altogether they added up to much more than Deep Waters could supply. Judging the competing claims was difficult from the office, and her technical staff usually just rolled their eyes and shrugged. “It’s like judging a liars’ contest,” one said.

  And then also reports were coming in from all around the basin of the new settlements under construction, and by no means all of the people building these settlements came from the Black Sea Group, or the metanats involved with them. A lot of them were simply unidentified—one of her dowsing crews would note the presence of a tent town which had no official existence, and leave it at that. And the two big canyon projects, in Dao Vallis and the Dao-Reull system, were clearly populated by many more people than could be accounted for in the official documentation—people who must therefore be living under assumed identities, like her, or else living out of the net entirely. Which was very interesting indeed.

  A circumHellas piste had just been completed the year before, a difficult piece of engineering as the rim of the basin was riven by cracks and ridges, and cratered by a heavy dose of ejecta reentry. But now the piste was in place, and Maya decided to satisfy her curiosity by taking a trip out to inspect all the Deep Waters projects in person, and look into some of the new settlements.

  To accompany her on this trip she requested
the company of one of their areologists, a young woman named Diana, whose reports had been coming in from the east basin. Her reports were terse and unremarkable, but Maya had learned from Michel that she was the child of Esther’s son, Paul. Esther had had Paul very soon after leaving Zygote, and as far as Maya knew, she had never told anyone who Paul’s father was. So it could have been Esther’s husband Kasei, in which case Diana was Jackie’s niece, and John and Hiroko’s great-granddaughter—or else it could have been Peter, as many supposed, in which case she was Jackie’s half-niece, and Ann and Simon’s great-granddaughter. Either way Maya found it intriguing, and in any case the young woman was one of the yonsei, a fourth-generation Martian, and as such interesting to Maya no matter what her ancestry.

  Interesting also in her own right, as it turned out when Maya met her in the Odessa offices a few days before their trip. With her great size (over two meters tall, and yet very rounded and muscular) and her fluid grace, and her high-cheekboned Asiatic features, she seemed a member of a new race, there to keep Maya company in this new corner of the world.

  It turned out that Diana was completely obsessed with the Hellas Basin and its hidden water, and she talked about it for hours, at such length and in such detail that Maya became convinced that the mystery of parentage was solved—such a marsmaniac must be related to Ann Clayborne, and so it followed that Paul had been fathered by Peter. Maya sat in the train seat beside the big young woman, watching her or looking out the window at the steep northern slope of the basin, asking questions, observing as Diana shifted her knees against the seat back in front of her. They did not make train seats big enough for the natives.

  One thing that fascinated Diana was that the Hellas Basin had proved to be ringed by much more underground water than had been predicted by the areological models. This discovery, made in the field over the last decade, had inspired the current Hellas project, turning the hypothetical sea from a nice idea into a tangible possibility. It had also forced the areologists to reconsider their theoretical models of early Martian history, and caused people to start looking around the rims of the other big impact basins on the planet; reconnaissance expeditions were under way in the Charitum and Nereidum Montes encircling Argyre, and in the hills ringing south Isidis.

  Around Hellas itself they were near to completing the inventory, and they had found perhaps thirty million cubic meters all told, though some dowsers argued they were by no means finished. “Is there a way to know when they’re finished?” Maya asked Diana, thinking about all the requests for resources flooding her office.

  Diana shrugged. “After a while you’ve just looked everywhere.”

  “What about the basin floor itself? Might the flooding be destroying our ability to get to some aquifers out there?”

  “No.” Almost no water, she told Maya, was located under the basin floor itself. The floor had been desiccated by the original impact, and now it consisted of about a kilometer’s depth of eolian sediment, underlain by a hard cake of brecciated rock, formed during the brief but stupendous pressures of the impact. These same pressures had also caused deep fracturing all around the rim of the basin, and it was this fracturing that had allowed unusually large amounts of outgassing from the interior of the planet. Vola-tiles from below had seeped up and cooled, and the water portion of the volátiles had pooled in liquid aquifers, and in many zones of highly saturated permafrost.

  “Quite an impact,” Maya observed.

  “It was big all right.” As a general rule, Diana said, impactors were about one-tenth the size of the crater or basin they made (like historical figures, Maya thought); so the impacting planetesimal in this case had been a body about two hundred kilometers in diameter, coming down on ancient cratered highland terrain. Signature traces of it indicated it had probably been an ordinary asteroid, carbonaceous chondrite for the most part, with lots of water and some nickel-iron in it. It had had a speed on arrival of about 72,000 kilometers per hour, and had hit at a slightly eastward angle, which explained the huge devastated region east of Hellas, as well as the high, relatively well-organized concentric ridges of the Hellespontus Montes to the west.

  Then Diana described another rule of thumb which caused Maya to free-associate analogies to human history: the bigger an impactor, the less of it survived the impact. Thus almost every bit of this one had vaporized in the cataclysmic strike—though there was a small gravitational bolide under Gledhill Crater, which some areologists claimed was almost certainly the buried remainder of the planetesimal, perhaps one ten-thousandth of the original or less, which they claimed would supply all the iron and nickel that they would ever need if they cared to go digging for it.

  “Is that feasible?” Maya asked.

  “Not really. Cheaper just to mine the asteroids.”

  Which they were doing, Maya thought darkly. That was what a prison sentence meant now, under the latest UNTA regime—years in the asteroid belt, operating the very strictly circumscribed mining ships and robots. Efficient, the Transitional Authority said. Prisons that were both remote and profitable.

  But Diana was still thinking about the basin’s awesome birth. The impact had occurred about three and a half billion years before the present, when the planet’s lithosphere had been thinner, and its interior hotter. Energies released by the impact were hard to imagine: the total energy created by humanity through all history was as nothing to it. And so the resulting volcanic activity had been considerable. Surrounding Hellas were a number of ancient volcanoes, which just postdated the impact, including Australis Tholus to the southwest, Amphitrites Patera to the south, and Hadriaca Patera and Tyrrhena Patera to the northeast. All of these volcanic regions had been found to have liquid water aquifers near them.

  Two of these aquifers had burst onto the surface in ancient times, leaving on the eastern slope of the basin two characteristic sinuous water-carved valleys: Dao Vallis, originating on the corrugated slopes of Hadriaca Patera; and farther south, a linked pair of valleys known as the Harmakhis-Reull system, which extended for a full thousand kilometers. The aquifers at the heads of these valleys had refilled over the eons since their outbreaks, and now big construction crews had tented Dao and were working on Harmakhis-Reull, and were letting the water from the aquifers run down the long enclosed canyons, to outlets on the basin floor. Maya was extremely interested in these big new additions to the habitable surface, and Diana, who knew them well, was going to take her to visit some friends in Dao.

  Their train glided along the northern rim of Hellas for all the first day, with the ice in view on the basin floor almost continually. They passed a little hillside town called Sebastopol, its stone walls Florentine yellow in the afternoon, and after that came to Hell’s Gate, the town at the bottom end of Dao Vallis. They walked out of the Hell’s Gate train station late in the afternoon, and looked down into a big new tent town, located under an enormous suspension bridge. The bridge supported the train piste, spanning Dao Vallis just up from the canyon’s mouth, so that its towers were over ten kilometers apart. From the canyon rim by the bridge, where the train station was, they could see down the widening mouth of the canyon onto the basin floor, stretching out under a lattice of kinky sun-stained clouds. In the other direction there was a view well up into the steep narrow world of the canyon proper. As they walked down a staired and switchbacked street into the town, the new tenting over the canyon was visible only as a certain red haze to the color of the evening sky, the result of a dusting of fines on the tenting materials. “We’ll go upstream tomorrow by way of the rim road,” Diana said, “and get an overview. Then come back down on the canyon floor, so you can see what it’s like down there.”

  They descended the street, which had 700 numbered steps. In Hell’s Gate’s downtown they walked around and had dinner, and then climbed back up to the Deep Waters office, which was on the valley wall just under the bridge. They stayed in rooms there, and next morning went to a garage by the train station and borrowed a small company rover
.

  Diana took the wheel and drove them northeast, paralleling the canyon rim on a road that ran next to the massive concrete foundation for the canyon’s tenting. Even though the fabrics were diaphanous to the point of vanishing, the sheer size of the roof made it a heavy weight to anchor. The concrete bulk of the foundation blocked their view down into the canyon itself, so that when they came to the first overtook, Maya had not seen into it since Hell’s Gate. Diana drove into a little parking lot up on the broad foundation itself, and they parked and put on helmets and got out of the car, and walked up a wooden staircase that seemed to ascend freestanding into the sky, although a closer look revealed first the clear aerogel beam supporting the staircase, and then the layers of tenting, stretching away from their beam to others that could not be seen. At the top of the stairs was a small railed viewing platform, with a prospect that gave a view of the canyon for many kilometers both upstream and downstream.

  And there was indeed a stream; the floor of Dao Vallis had a river in it. The canyon floor was dotted with green, or to be more precise, a collection of greens. Maya identified, tamarisk, cotton-wood, aspen, cypress, sycamore, scrub oak, snow bamboo, sage—and then, on the steep talus and boulder slopes footing the canyon walls, many varieties of shrubs and low creepers, and of course sedge, and moss, and lichen. And running through this exquisite arboretum, a river.

  It was not a blue stream with white rapids. The water in the slower stretches was opaque, and the color of rust. In the rapids and waterfalls it foamed bright shades of pink. Classic Martian tones, caused, Diana said, by the fines that were suspended in the water like glacial silt—also by the reflected color of the sky, which was today a kind of hazy mauve, going lavender around the veiled sun, as yellow as the iris of a tiger’s eye.

  But no matter the color of the water—it was a running river, in an obviously riverine valley, placid in some places, agitated in others, with gravel fords, sandbars, braided sections, crumbling lemniscate islands, there a big deep lazy oxbow, frequent rapids, and far upstream, a couple of small falls. Under the tallest waterfall they could see the pink foam turn almost white, and patches of white were then carried downstream, to catch on boulders and snags sticking out from the bank.
