And so: fast-growing lichens. Radiation-resistant algae. Extreme-cold fungi. Halophylic bacteria, eating salt and excreting oxygen. Surarctic mosses. An entire taxonomy of new kinds of life, all partially adapted to the surface of Mars, all out there having a try at it. Some species went extinct: natural selection. Some prospered: survival of the fittest. Some prospered wildly, at the expense of other organisms; and then chemicals in their excretions activated their suicide genes, and they died back until the levels of those chemicals dropped again.
So life adapts to conditions. And at the same time, conditions are changed by life. That is one of the definitions of life: organism and environment change together in a reciprocal arrangement, as they are two manifestations of an ecology, two parts of a whole.
And so: black fuzz on the polar ice. Black fuzz on the ragged surfaces of bubbled rock. Pale green patches on the ground. Bigger grains of frost in the air. Animacules shoving through the depths of the regolith, like trillions of tiny moles.
At first it was nearly invisible, and very slow. With a cold snap or a solar storm there would be massive die-offs, whole species extinct in a night. But the remains of the dead fed other creatures; conditions were thus easier for them, and the process picked up momentum. Bacteria reproduce quickly, doubling their mass many times a day if conditions are right: the mathematical possibilities for the speed of their growth are staggering, and although environmental constraints – especially on Mars – keep all actual growth far from the mathematical limits, still, the new organisms, the areophytes, quickly reproduced, sometimes mutated, always died, and the new life fed on the compost of their ancestors, and reproduced again. Lived and died; and the soil and air left behind were different than they were before these millions of brief generations.
And so one morning the sun rises, shooting long rays through the ragged cloud cover, up the length of Valles Marineris. On the north wall every horizontal face is black and yellow and olive and gray and green, all with the warty surfaces of lichen. Plates of lichen drip down the vertical faces of stone, which stand as they always have, stony, and cracked, and red; but now mottled, as if with lace.
Michel Duval dreamed of home. He was swimming in the surf off the point at Villefranche-sur-Mer, the warm August water lifting him up and down. It was windy and near sunset and the water was a sloppy white bronze, the sunlight bouncing all over it. The waves were big for the Mediterranean, swift breakers that rose up all riven with wind chop to crash in quick uneven lines, allowing him to ride them for a moment. Then it was under in a tumble of bubbles and sand, and back up into a burst of gold light and the taste of salt in everything, his eyes stinging voluptuously. Big black pelicans rode air cushions just over the swells, soared into steep clumsy turns, stalled, dropped into the water around him. They half-folded their wings when they dove, making adjustments with them until the actual moment of the awkward crash into the water. Often they came up gulping small fish. Just meters from him one splashed in, silhouetted against the sun like a Stuka or a pterodactyl. Cool and warm, immersed in salt, he bobbed on the swell and blinked, blinded by salt light. A breaking wave looked like diamonds smashed to cream.
His phone rang.
His phone rang. It was Ursula and Phyllis, to tell him that Maya was having another fit and was inconsolable. He got up, put on unders and went to the bathroom. Waves leaped over a line of backwash. Maya, depressed again. Last time he had seen her she had been in high spirits, almost euphoric, and that was what, a week ago? But that was Maya. Maya was crazy. Crazy in a Russian way, however, which meant she was a power to be reckoned with. Mother Russia! The church and the communists both had tried to eradicate the matriarchy that had preceded them; and all they had achieved was a flood of bitter emasculating scorn, a whole nation full of contemptuous russalkas and baba yagas and twenty-hour-a-day superwomen, living in a nearly parthenogenic culture of mothers, daughters, babushkas, granddaughters. Yet still necessarily absorbed in their relationships with men, desperately trying to find the lost father, the perfect mate. Or just a man who would pull his share of the load. Finding that great love, and then more often than not destroying it. Crazy!
Well, it was dangerous to generalize. But Maya was a classic case. Moody, angry, flirtatious, brilliant, charming, manipulative, intense – and now filling his office like a huge slab of dejection, her eyes red-rimmed and bloodshot, her mouth haggard. Ursula and Phyllis nodded and whispered thanks to Michel for getting up so early, and left. He went to the Venetian blinds and opened them, and the light from the central dome poured in. He saw again that Maya was a beautiful woman, with wild lustrous hair and a dark charismatic gaze, immediate and direct. It was dismaying to see her this upset, he never got used to it, it contrasted too sharply with her usual vivaciousness, the way she would put a finger to your arm as she rattled on in a confiding tone about one fascinating thing or other …
All strangely mimicked by this desperate creature, who leaned forward onto his desk and began to tell him in a ragged hoarse voice about the latest scene in the unfolding drama of her and John, and then, again, Frank. Apparently she had gotten angry at John for refusing to help her in a plan she had to get some of the Russian-based multinationals to underwrite the development of settlements in Hellas Basin, which being the deepest point on Mars was going to be first to benefit from the atmospheric changes they were beginning to see. The air pressure at Low Point, four kilometers below the datum, was always going to be ten times thicker than that on top of the great volcanoes, and three times thicker than at the datum: it was going to be the first human-viable place, perfect for development.
But apparently John preferred to work through UNOMA and governments. And this was just one of the many basic political disagreements which were beginning to infect their personal life, to the point that they were fighting pretty frequently about other things, things that didn’t matter, things about which they had never fought before.
Watching her Michel almost said, John wants you irritated with him. He wasn’t sure what John would say to that. Maya rubbed her eyes, leaned her forehead on his desk, revealing the back of her neck and her broad rangy shoulders. She would never look this distraught in front of most of Underhill; it was an intimacy between them, something she only did with him. It was as if she had taken off her clothes. People didn’t understand that true intimacy did not consist of sexual intercourse, which could be done with strangers and in a state of total alienation; intimacy consisted of talking for hours about what was most important in one’s life. Although it was true she would be beautiful naked, she had perfect proportions. He recalled the way she looked swimming in the pool, doing the backstroke in a blue bathing suit cut high over the hipbones. A Mediterranean image: he was floating in the water at Villefranche, everything flooded with sunset’s amber light, and he was looking in at the beach where men and women were walking, naked except for the neon triangles of cache-sexe bathing suits – brown-skinned bare-breasted women, walking in pairs like dancers in the sunlight – then dolphins sliced out of the water between him and the beach, their sleek black bodies rounded like the women’s—
But now Maya was talking about Frank. Frank, who had a sixth sense for trouble between John and Maya (six would not be necessary), and who came running to Maya every time he felt the signs, to walk with her and talk about his vision of Mars, which was progressive, exciting, ambitious, everything that John’s was not. “Frank is so much more dynamic than John these days, I don’t know why.”
“Because he agrees with you,” Michel said.
Maya shrugged. “Perhaps that’s all I mean. But we have a chance to build a whole civilization here, we do. But John is so …” Big sigh. “And yet I love him, I really do. But …”
She talked for a while about their past, how their courtship had saved the voyage out from anarchy (or at least ennui), how John’s easy-going stability had been
