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.
