But she was still president of the executive council, and despite her resolve, every day they bound her to the job a little more tightly, with “developments” of all kinds. German immigrants wanted to build a new harbor town called Blochs Hoffnung on the peninsula that cut the North Sea in half, and then dig a broad canal through the peninsula. Red ecoteurs objected to this plan, and blew up the piste running down the peninsula. They blew up the piste leading to the top of Biblis Patera as well, to indicate they objected to that as well. Ecopoets in Amazonia wanted to start massive forest fires. Other ecopoets in Kasei wanted to remove the fire-dependent forest that Sax had planted in the great curve of the valley (this petition was the first to receive unanimous approval from the GEC). Reds living around White Rock, an eighteen-kilometer-wide pure white mesa, wanted it declared a “kami site” forbidden to human access. A Sabishii design team was recommending that they build a new capital city on the North-Sea coast at 0 longitude, where there was a deep bay. New Clarke was getting crowded with what looked suspiciously like metanat security snoopertroopers. The Da Vinci techs wanted to give control of Martian space over to an agency of the global government that didn’t exist. Senzeni Na wanted to fill their mohole. The Chinese were requesting permission to build an entirely new space elevator tethered near Schiaparelli Crater, to accommodate their own emigration, and contract out to others. Immigration was growing every month.

Nadia dealt with all these issues in half-hour increments scheduled by Art, and so the days passed in a blur. It got very difficult to stay aware that some of these matters were much more important than others. The Chinese, for instance, would flood Mars with immigrants if they got half a chance . . . and the Red ecoteurs were getting more outrageous; there had even been death threats made against Nadia herself. She now had escorts when she left her apartment, and the apartment was discreetly guarded. Nadia ignored that, and continued to work on the issues, and to work the council to keep a majority on her side in the votes that mattered to her. She established good working relations with Zeyk and Mikhail, and even with Marion. Things never went quite right with Ariadne again, however, which was a lesson learned twice; but learned well because of that.

So she did the job. But all the time she wanted off Pavonis. Art saw her patience get shorter by the day; she knew by his look that she was becoming crochety, crabby, dictatorial; she knew it, but could not help it. After meetings with frivolous or obstructionist people she often unleashed a torrent of vicious abuse, in a steady low cursing voice that Art obviously found unnerving. Delegations would come in demanding an end to the death penalty, or the right to build in the Olympus Mons caldera, or a free eighth spot on the executive council, and as soon as the door closed Nadia would say, “Well there’s a bunch of fucking idiots for you, stupid fools never even thought about tie votes, never occurred to them that taking someone else’s life abrogates your own right to live,” and so on. The new police captured a group of Red ecoteurs who had tried to blow up the Socket again, and in the process killed a security guard out of his position, and she was the hardest judge they had: “Execute them!” she exclaimed. “Look, you kill someone, you lose your right to live. Execute them or else exile them from Mars for life— make them pay in a way that really gets the rest of the Reds’ attention.”

“Well,” Art said uneasily. “Well, after all.” But on she raged. She couldn’t stop until she felt less angry. And Art could see that it was getting harder every time.

Flailing a bit himself, he recommended she start another conference, like the one in Sabishii she had missed; and make sure she made this one. Organizing the efforts of different organizations for a single cause; this was not really building, Nadia thought, but it looked like it would have to do.

The fight in Cairo had gotten her thinking about the hydrological cycle, and what would happen when the ice began to melt. If they could set up some kind of plan for a water cycle, even only an approximation, then it might go far toward reducing conflicts over water. So she decided to see what could be done.

As often happened these days when she thought about global issues, she found herself wanting to talk to Sax about it. The travelers to Earth were almost back now, close enough that transmission delay was insignificant, it was almost like having a normal wrist conversation. So Nadia spent evenings talking with Sax about terraforming. More than once he surprised her utterly; he did not hold the opinions she had imagined he would hold, he seemed always to be changing. “I want to keep things wild,” he said one night.

“What do you mean?” she asked.

His face took on the puzzled expression it wore when he was thinking hard. It was considerably longer than the transmission delay before he replied: “Many things. It’s a complicated word. But— I mean— I want to maintain the primal landscape, as much as possible.”

Nadia could censor out her laughter at this; but still Sax said, “What do you find amusing?”

“Oh nothing. It’s just you sound like, I don’t know, like some of the Reds. Or the people in Christianopolis, they’re not Reds, but they said almost the same thing to me, last week. They want to keep the primal landscape of the far south preserved. I’ve helped them to set up a conference to talk about southern watersheds.”

“I thought you were working on greenhouse gases?”

“They won’t let me work, I have to be president. But I am going to go to this conference.”

“Good idea.”

The Japanese settlers in Messhi Hoko (which meant “self-sacrifice for the sake of the group”) came to the council to demand that more land and water be dedicated to their tent high on south Tharsis. Nadia walked out on them, and flew with Art down to Christianopolis, in the far south.

The little town (and it seemed very little after Sheffield and Cairo) was set in Phillips Rim Crater Four, at latitude sixty-seven degrees south. During the Year Without Summer the far south had experienced many severe storms, dropping about four meters of new snow, an unprecedented amount; the previous record for a year had been less than one. Now it was Ls 281, just after perihelion, and high summer in the south. And the various abatement strategies for avoiding an ice age seemed to be working well; most of the new snow had melted in a hot spring, and now there were round lakes on every crater floor. The pond in the center of Christianopolis was about three meters deep, and three hundred meters across; this was fine with the Christians, as it gave them a nice park pond. But if the same thing happened every winter— and the meteorologists believed that the coming winters would drop even more snow, and the coming summers get ever warmer— then their town would quickly be inundated by snowmelt, and Phillips Rim Crater Four become a lake full to the brim. And this was true for craters all over Mars.

The conference in Christianopolis had been convened to discuss strategies to deal with this situation. Nadia had done what she could to get influential people down to it, including meteorologists, hydrologists, and engineers, and the possibility of Sax, whose return was imminent. The problem of crater flooding was to be only the initial point of discussion for the whole question of watersheds, and the planetary hydrological cycle itself.

The crater problem specifically was to be solved as Nadia had predicted: plumbing. They would treat the craters like bathtubs, and drill drains to empty them. The brecciated pans under the dusty crater floors were extremely hard, but they could be tunneled through robotically; then install pumps and filters and pump the water out, keeping a central pond or lake if one wanted, or draining it dry.

But what were they going to do with the water they pumped out? The southern highlands were everywhere lumpy, shattered, pocked, cracked, hillocky, scarped, slumped, fissured, and fractured; when analyzed as potential watersheds, they were hopeless. Nothing led anywhere; there was no downhill for long. The entire south was a plateau three to four kilometers above the old datum, with only local bumps and dips. Never had Nadia seen more clearly the difference between this highland and any continent on Earth. On Earth, tectonic movement had pushed up mountains every few-score million years, and then water had run down these fresh slopes, following the paths of least resistance back to the sea, carving the fractal vein patterns of watersheds everywhere. Even the dry basin regions on Earth were seamed with arroyos and dotted with playas. In the Martian south, however, the meteoric bombardment of the Noachian had hammered the land ferociously, leaving craters and ejecta everywhere; and then the battered irregular wasteland had lain there for two billion years under the ceaseless scouring of the dusty winds, tearing at every flaw. If they poured water onto this pummeled land they would end up with a crazy quilt of short streams, running down local inclines to the nearest rimless crater. Hardly any streams would make it to the sea in the north, or even into the Hellas or Argyre basins, both of which were ringed by mountain ranges of their own ejecta.

There were, however, a few exceptions to this situation. The Noachian Age had been followed by a brief “warm wet period” in the late Hesperian, a period perhaps as short as a hundred million years, when a thick warm CO2 atmosphere had allowed liquid water to run on the surface, carving some river channels down the gentle tilts of the plateau, between crater aprons diverting them this way and that. And these watercourses had of course remained after the atmosphere had frozen out, empty arroyos gradually widened by the wind. These fossil riverbeds, like Nirgal Vallis, Warrego Valles, Protva Valles, Patana Valles, or Oltis Vallis, were narrow sinuous canyons, true riverine canyons rather than grabens or fossae. Some of them even had immature tributary systems. So efforts to design a macro-watershed system for the south naturally used these canyons as primary watercourses, with water pumped to the head of every tributary. Then there were also a number of old lava channels that could easily become rivers, as the lava, like the water, had tended to follow the path of least resistance downhill. And there were a number of tilted graben fractures and fissures, as at the foot of the Eridania Scopulus, that could likewise be turned to use.

In the conference, big globes of Mars were marked up daily to display different water regimes. There were also rooms full of 3-D topo maps, with groups standing around different watershed systems, arguing their advantages and disadvantages, or simply contemplating them, or fiddling with the controls to change them, restlessly, from one pattern to another. Nadia wandered the rooms looking at these hydrographies, learning much about the southern hemisphere that she had never known. There was a six-kilometer-high mountain near Richardson Crater, in the far south. The south polar cap itself was quite high. Dorsa Brevia, on the other hand, crossed a depression that looked like a ray cut out from the Hellas impact, a valley so deep that it ought to become a lake, an idea that the Dorsa Brevians naturally did not like. And certainly the area could be drained if they cared to do it. There were scores of variant plans, and every single system was strange looking to Nadia. Never had she seen so clearly how different a gravity-driven fractal was from impact randomness. In the inchoate meteoric landscape, almost anything was possible, because nothing was obvious— nothing except for the fact that in any possible system, some canals and tunnels would have to be built. Her new finger itched with the desire to get out there and run a bulldozer or a tunnel borer.

Gradually the most efficient, or logical, or aesthetically pleasing plans began to emerge from the proposals, the best for each region being patched together, in a kind of mosaic. In the eastern quadrant of the deep south, streams would tend to run toward Hellas Basin and through a couple of gorges into the Hellas Sea, which was fine. Dorsa Brevia accepted a plan to have their town’s lava tunnel ridge become a kind of dam, crossing a watershed transversely so that there was a lake above it and a river below it, coursing down to Hellas. Around the south polar cap, snowfall would remain frozen, but most of the meteorologists predicted that when things stabilized there wouldn’t be much snowfall on the pole, that it would become a cold desert like Antarctica. Eventually of course they would end up with a largish ice cap, and then part of it would pool down into the huge depression under the Promethei Rupes, another partially erased old impact basin. If they didn’t want too large of a southern ice cap, they would have to melt and pump some of the water back north, into the Hellas Sea perhaps. They would have to do some similar pumping in Argyre Basin, if they decided to keep Argyre dry. A group of moderate Red lawyers was even now insisting on this before the GEC, arguing that one of the two great dune-filled impact basins on the planet ought to be preserved. It seemed certain this claim would receive a favorable judgment from the court, and so all the watersheds around Argyre had to take this into account.

Sax had designed his own southern watershed plan, which he sent to the conference from their rocket as it aerobraked into orbital insertion, to be considered with all the rest. It minimized surface water, emptied most craters, used tunnels extensively, and channelized almost all drained water into the fossil river canyons. In his plan vast areas of the south would stay arid desert, making for a hemisphere of dry tableland, cut deeply by a few narrow river-bottomed canyons. “Water is returned north,” he explained to Nadia in a call, “and if you stay up on the plateaus, it will look like it always did, almost.”

So that Ann would like it, he was saying.

“Good idea,” Nadia said.

And indeed Sax’s plan was not that much different than the consensus being hammered out by the conference. Wet north, dry south; one more dualism to add to the great dichotomy. And to have the old river canyons running with water again was satisfying. A good-looking plan, given the terrain.

But the days were long gone when Sax or anyone else could choose a terraforming project and then go out and do it. Nadia could see that Sax hadn’t fully understood this. Ever since the beginning, when he had slipped algae-filled windmills into the field without the knowledge or approval of anyone but his accomplices, he had been working on his own. It was an ingrained habit of mind, and now he seemed to forget the review process that any watershed plan was going to have to go through in the environmental courts. But the process was there, inescapable now, and because of the grand gesture, half the fifty GEC justices were Reds of one shade or another. Any watershed proposal from a conference including Sax Russell, even as a teleparticipant, was going to get close and suspicious scrutiny.

But it seemed to Nadia that if the Red justices looked carefully at the proposal, they would have to be amazed at Sax’s approach. Indeed it represented a kind of road-to-Damascus conversion— inexplicable, given Sax’s history. Unless you knew all of it. But Nadia understood: he was trying to please Ann. Nadia doubted that was possible, but she liked to see Sax try. “A man full of surprises,” she remarked to Art.

“Brain trauma will do that.”

In any case, when the conference was done they had designed an entire hydrography, designating all the future major lakes and rivers and streams of the southern hemisphere. The plan would eventually have to be integrated with similar plans for the northern hemisphere, which were in considerable disarray by comparison, because of the uncertainty about just how big the northern sea was going to be. Water was no longer being actively pumped up out of permafrost and aquifers— indeed many of the pumping stations had been blown up in the last year by Red ecoteurs— but some water was still rising, under the weight put on the land by the water already pumped. And summer runoff was flowing into Vastitas, more every year, both from the northern polar cap and the Great Escarpment; Vastitas was the catchment basin for huge watersheds on all sides. So a lot of water was going to pour into it every summer. On the other hand, a lot of water was always being stripped off by the arid winds, eventually precipitating elsewhere. And water would evaporate much faster than the ice currently there was subliming. So calculating how much was leaving and how much coming back was a modeler’s field day, and estimates were still all over the map, literally so in that differences in prediction led to putative shorelines that were in some cases hundreds of kilometers apart.

That uncertainty would delay any GECO on the south, Nadia thought; in essence the court had to try to correlate all the current data, and evaluate the models, and then prescribe a sea level, and approve all watersheds accordingly. The fate of Argyre Basin in particular seemed impossible to decide at this point, before there was a northern plan; some plans called for pumping water up into Argyre from the northern sea if the northern sea got too full, to avoid flooding the Marineris canyons, South Fossa, and the new harbor towns being built. Radical Reds were already threatening to build “west-bank settlements” all over Argyre to forestall any such move.

So the GEC had yet another big issue to solve. Clearly it was becoming the most important political body on Mars; with the constitution and its own previous rulings to guide it, it was ruling on almost every aspect of their future. Nadia thought that was probably as it should be; or at least that there was nothing wrong with it. They needed decisions with global ramifications reviewed globally, that was what it came down to.

But come what may in the courts, a provisional plan for the southern hemisphere had at least been formulated. And to everyone’s surprise, the GEC gave the plan a positive preliminary judgment very soon after it was submitted— because, their ruling said, it could be activated in stages as water fell on the south, and it proceeded in much the same fashion through its first stages no matter what the eventual sea level in the north became. So there was no reason to delay beginning.

Art came in beaming with the news. “We can begin plumbing,” he said.

• • •

But of course Nadia couldn’t. There were meetings in Sheffield to go back to, decisions to be made, people to be convinced or coerced. Doggedly she did that work, stubbornly doing her duty whether she liked it or not, and as time passed she got better and better at it. She saw how she could subtly pressure other people to get her way; saw how people would do her bidding if she asked or suggested in certain ways. The constant stream of decisions honed some of her views; she found that it helped to have at least some consciously held political principles, rather than judging each case by instinct. It also helped to have reliable allies, on the council and elsewhere, rather than being a supposedly neutral and independent person. And so by degrees she found herself joining the Bogdanovists, who, to her surprise, conformed more closely to her political philosophy than anything else on Mars. Of course her reading of Bogdanovism was relatively simple: things should be just, Arkady had insisted, and everyone free and equal; the past didn’t matter; they needed to invent new forms whenever the old ones looked unfair or impractical, which was often; Mars was the only reality that counted, at least to them. Using these as her guiding principles, she found it easier to make up her mind about things, to see a course and cut for it directly.

Also she became more and more ruthless. From time to time she felt freshly how power could corrupt, felt it as a slight nausea within her. But she was getting habituated. She clashed often with Ariadne, and when she recalled the remorse she had felt after her first wrangle with the young Minoan, it seemed to her ridiculously overfastidious; she was far tougher than that every day now on people who crossed her, she showed the knives in meeting after meeting, in calculated microbursts of brutality that put people in line very effectively indeed. In fact the more she allowed herself to release little outbursts of fury and scorn, the more certainly she could control them and put them to some use. She was a power; and people knew it; and power was corrosive. Power was powerful, in more ways than one. And now Nadia felt very little remorse about that; they deserved a pop on the nose, generally; they had thought they were going to get a harmless old babushka to sit in the big chair while they worked their games on each other, but the big chair was the power seat, and she was damned if she was going to go through all this shit and not use some of that power to try to get what she wanted.

And so less and less often did she feel how ugly it was. Once when she did, after a particularly hard-nosed day, she thumped down in a chair and almost cried, sick with disgust. Only seven months of her three m-years had passed. What would she become by the time her stint was done? Already she was used to power; by then she might even like it.

Art, worried by all this, squinted at her over their breakfast table. “Well,” he said once, after she explained what was bothering her, “power is power.” He was thinking hard. “You’re the first president of Mars. So in a way you define the office. Maybe you should declare you’re only going to work the one month and not the two months, and delegate the two months to your staff. Something like that.”

She stared at him, mouth full of toast.

Later that week she abandoned Sheffield and went south again, joining a caravan of people working their way from crater to crater, installing drainage systems. Every crater had variations, but essentially it was a matter of picking the right angle to emerge from the crater apron, and then setting the robots to work. Von Karman, Du Toit, Schmidt, Agassiz, Heaviside, Bianchini, Lau, Chamberlin, Stoney, Dokuchaev, Trumpler, Keeler, Charlier, Suess . . . they plumbed all of those craters, and many more unnamed ones, although the craters were taking on names even faster than they drilled them: 85 South, Too Dark, Fool’s Hope, Shanghai, Hiroko Slept Here, Fourier, Cole, Proudhon, Bellamy, Hudson, Kaif, 47 Ronin, Makoto, Kino Doku, Ka Ko, Mondragon. The migration from one crater to the next reminded Nadia of her trips around the south polar cap during the underground years; except now everything was out in the open, and through the nearly nightless midsummer days the team luxuriated in the sun, in the glary light off the crater lakes. They traveled across rough frozen bogs brilliant with sunny meltwater and meadow grass, and always of course they crossed the rust-and-black rockscape breaking out into the light, ring after ring, ridge after ridge. They plumbed craters and laid watershed pipes, and attached greenhouse-gas factories to the excavators whenever the rock had any gas feedstocks in it.

But hardly any of that turned out to be work in the sense Nadia meant. She missed the old days. Of course operating a bulldozer had not been hand labor, but one’s touch with the blade had been a very physical skill, and the repeated gearshifts physically taxing; and it was all around a higher level of engagement than this “work,” which consisted of talking to AIs and then walking around and watching humming and buzzing teams of waist-high robot diggers, city-block-sized mobile factory units, tunnel moles with diamond teeth that grew back like sharks’ teeth— everything made of bioceramic/metallic alloys stronger than the elevator cable, all of it out there doing it all by itself. It just wasn’t what she had in mind.
