in favor of the Russell program. This reminder of their enormous fame on Earth, their existence as characters in an ongoing TV drama, was always peculiar and unsettling; after the flurry of TV specials and interviews following touchdown, they had tended to forget the ongoing video transmissions, absorbed in the daily reality of their lives. But the video cameras were still shooting tape to send back home; and there were a lot of people on Earth who were fans of the show.

      So nearly everyone had an opinion. Polls showed that most supported the Russell Program, an informal name for Sax’s plans to terraform the planet by all means possible, as fast as they could. But the minority who backed Ann’s hands-off attitude tended to be more vehement in their belief, insisting that it had immediate applications to the Antarctic policy, and indeed to all Terran environmental policy. Meanwhile different poll questions made it clear that many people were fascinated by Hiroko and the farming project, while others called themselves Bogdanovists; Arkady had been sending back lots of video from Phobos, and Phobos was good video, a real spectacle of architecture and engineering. New Terran hotels and commercial complexes were already imitating some of its features, there was an architectural movement called Bogdanovism, as well as other movements interested in him that were more concentrated on social and economic reforms in the world order.

      But terraforming was near the center of all these debates, and the colonists’ disagreements about it were played out on the largest possible public stage. Some of them reacted by avoiding the cameras and requests for interviews; “It’s just what I came to get away from,” Hiroko’s assistant Iwao said, and quite a few agreed with him. Most of the rest didn’t care one way or the other; a few seemed actually to like it. Phyllis’s weekly program, for instance, was carried by both Christian cable stations and business analysis programs all over the world. But no matter how they dealt with it, looking at the polls and listening to the talk made it obvious that most people on Earth and on Mars assumed that terraforming would take place. It was not a question of whether but of when, and how much. Among the colonists themselves this was nearly the universal view. Very few sided with Ann: Simon of course; perhaps Ursula and Sasha; perhaps Hiroko; in his way John, and now in her way Nadia. There were more of these “reds” back on Earth, but they necessarily held the position as a theory, an aesthetic judgement. The strongest point to their arguments, and thus the one that Ann emphasized most often in her communiques back to Earth, was the possibility of indigenous life. “If there is Martian life here,” Ann would say, “the radical alteration of the climate might kill it off. We cannot intrude on the situation while the status of life on Mars is unknown; it’s unscientific, and worse, it’s immoral.”

      Many agreed with that, including a lot of the Terran scientific community, which influenced the UNOMA committee charged with overseeing the colony. But every time Sax heard the argument he blinked rapidly. “There’s no sign of life on the surface, past or present,” he would say mildly. “If it does exist it has to be underground, near volcanic vents I suppose. But even if there is life down there, we could search for ten thousand years and never find it, nor eliminate the possibility it isn’t down there somewhere else, somewhere we haven’t looked. So waiting until we know for sure that there is no life” – which was a fairly common position among moderates – “effectively means waiting forever. For a remote possibility which terraforming wouldn’t immediately endanger anyway.”

      “Of course it would,” Ann would retort. “Maybe not immediately, but eventually the permafrost would melt, there would be movement through the hydrosphere, and contamination of all of it by warmer water and Terran lifeforms, bacteria, viruses, algae. It might take a while, but it would surely happen. And we can’t risk that.”

      Sax would shrug. “First, it’s postulated life, very low probability. Second, it wouldn’t be endangered for centuries. We could presumably locate it and protect it in that time.”

      “But we may not be able to find it.”

      “So we stop for low-probability life we can never actually find?”

      Ann shrugged. “We have to, unless you want to argue that it’s okay to destroy life on other planets, as long as we can’t find it. And don’t forget; indigenous life on Mars would be the biggest story of all time, it would have implications for the galactic frequency of life that are impossible to exaggerate. Looking for life is one of the main reasons we’re here!”

      “Well,” Sax would say, “in the meantime, life that we are quite sure exists is being exposed to an extraordinarily high amount of radiation. If we don’t do something to lessen it, we may not be able to stay here. We need a thicker atmosphere to cut down on radiation.”

      This was not a reply to Ann’s point but the substitution of another one, and it was an argument that was very influential. Millions on Earth wanted to come to Mars, to the “new frontier,” where life was an adventure again; waiting lists for emigration both real and fake were massively oversubscribed. But no one wanted to live in a bath of mutagenic radiation, and the practical desire to make the planet safe for humans was stronger in most people than the desire to preserve the lifeless landscape already there, or to protect a postulated indigenous life that many scientists assured them did not exist.

      So it did seem, even among those urging caution, that terraforming was going to happen. A subcommittee of UNOMA had been convened to study the issue, and on Earth it was now in the nature of a given, an unavoidable part of progress, a natural part of the order of things. A manifest destiny.

      On Mars, however, the issue was both more open and more pressing, not so much a matter of philosophy as of daily life, of frigid poisonous air and the radiation being taken; and among those in favor of terraforming, a significant group was clustering around Sax – a group that not only wanted to do it, but to do it as fast as possible. What this meant in practice no one was sure; estimates of the time it would take to get to a “human-viable surface” ranged from a century to ten thousand years, with extreme opinions on either end, from thirty years (Phyllis) to a hundred thousand years (Iwao). Phyllis would say, “God gave us this planet to make in our image, to create a new Eden". Simon would say, “If the permafrost melts we’d be living on a collapsing landscape, and a lot of us would be killed". Arguments wandered over a wide range of issues: salt levels, peroxide levels, radiation levels, the look of the land, possibly lethal mutations of genetically engineered micro-organisms, and so on.

      “We can try to model it,” Sax said, “but the truth is we’ll never be able to model it adequately. It’s too big and there are too many factors, many of them unknown. But what we will learn from it will be useful in controlling Earth’s climate, in avoiding global warming or a future ice age. It’s an experiment, a big one, and it will always be an ongoing experiment, with nothing guaranteed or known for sure. But that’s what science is.”

      People would nod at this.

      Arkady as always was thinking of the political point of view. “We can never be self-sufficient unless we do terraforming,” he pointed out. “We need to terraform in order to make the planet ours, so that we will have the material basis for independence.”

      People would roll their eyes at this. But it meant that Sax and Arkady were allies of a sort, and that was a powerful combination. And so the arguments would go around, again and again and again, endlessly.

      And now Underhill was nearly complete, a functioning and in most ways a self-sufficient village. Now it was possible to act further; now they had to decide what to do next. And most of them wanted to terraform. Any number of projects had been proposed to begin the process, with advocates for each, usually those who would be responsible for doing it. This was an important part of terraforming’s attraction; every discipline could contribute to the enterprise in one way or another, so it had broad-based support. The alchemists talked about physical and mechanical means to add heat to the system; the climatologists debated influencing the weather; the biosphere team talked about ecological systems theories to be tested. The bioengineers were already working on new micro-organisms; they were shifting, clipping and recombining genes from algae, methanogens, cyanobacteria, and lichens, trying to come up with organisms that would survive on the present Martian surface, or under it. One day they invited Arkady to take a look at what they were doing, and Nadia went along with
