fountain of youth, I tell you.”

      “You’ll have to send up some recordings,” Arkady said. He tried to sing: “I can’t give you any thing but love, baby!” Phobos was about over the horizon, he had just been calling to say hi. “So this is your 1947,” he said before he went.

      Nadia put her tools away, singing the song correctly. And she understood that what Arkady had said was true; something had happened to her similar to what had happened to Armstrong in 1947 – because despite the miserable conditions, her youthful years in Siberia had been the happiest of her life, they really had. And then she had endured twenty years of big band cosmonautics, bureaucracy, simulations, an indoor life – all to get here. And now suddenly she was out in the open again, building things with her hands, operating heavy machinery, solving problems a hundred times a day, just like Siberia only better. It was just like Satchmo’s return!

      Thus when Hiroko came up and said, “Nadia, this crescent wrench is absolutely frozen in this position,” Nadia sang to her, “That’s the only thing I’m thinking of – baby!” and took the crescent wrench and slammed it against a table like a hammer, and twiddled the dial to show Hiroko it was unstuck, and laughed at her expression. “The engineer’s solution,” she explained, and went humming into the lock, thinking how funny Hiroko was, a woman who held their whole ecosystem in her head, but couldn’t hammer a nail straight.

      And that night she talked over the day’s work with Sax, and spoke to Spencer about glass, and in the middle of that conversation crashed on her bunk and snuggled her head into her pillow, feeling totally luxurious, the glorious final chorus of “Ain’t Misbehaving” chasing her off to sleep.

      But things change as time passes; nothing lasts, not even stone, not even happiness. “Do you realize it’s Ls 170 already?” Phyllis said one night. “Didn’t we land at Ls 7?”

      So they had been on Mars for half a Martian year. Phyllis was using the calendar devised by planetary scientists; among the colonists it was becoming more common than the Terran system. Mars’s year was 668.6 local days long, and to tell where they were in this long year it took the Ls calendar. This system declared the line between the sun and Mars at its northern spring equinox to be 0°, and then the year was divided into 360°, so that Ls = 0°–90° was the northern spring, 90–180° the northern summer, 180–270° the fall, and 270–360° (or 0° again) the winter.

      This simple situation was complicated by the eccentricity of the Martian orbit, which is extreme by Terran standards, for at perihelion Mars is about forty-three million kilometers closer to the sun than it is at aphelion, and thus receiving about 45% more sunlight. This fluctuation makes the southern and northern seasons quite unequal. Perihelion arrives every year at Ls = 250°, late in the southern spring; so southern springs and summers are much hotter than northern springs and summers, with peak temperatures as much as thirty degrees higher. Southern autumns and winters are colder, however, occurring as they do near aphelion; so much colder that the southern polar cap is mostly carbon dioxide, while the northern one is mostly water ice.

      So the south was the hemisphere of extremes, the north that of moderation. And the orbital eccentricity caused one other feature of note; planets move faster the closer they are to the sun, so the seasons near perihelion are shorter than those near aphelion; the northern autumn is 143 days long, for instance, while northern spring is 194. Spring fifty-one days longer than autumn! Some claimed this alone made it worth settling in the north.

      In any case, in the north they were; and spring had arrived. The days got longer by a little bit every day and the work went on. The area around the base got more cluttered, more criss-crossed with tracks; they had laid a cement road to Chernobyl and the base itself was now so big that from the trailer park it extended over the horizon in all directions: the alchemists’ quarter and the Chernobyl road to the east, the permanent habitat to the north, the storage area and the farm to the west, and the biomed center to the south.

      Eventually everyone moved into the finished chambers of the permanent habitat. The nightly conferences there were shorter and more routinized than they had been in the trailer park, and days went by when Nadia got no calls for help. There were some people she saw only once in a while; the biomed crew in its labs, Phyllis’s prospecting unit, even Ann. One night Ann flopped on her bed next to Nadia’s, and invited her to go along on an exploration to Hebes Chasma, some 130 kilometers to the southwest. Obviously Ann wanted to show her something outside the base area; but Nadia declined. “I’ve got too much work to do, you know.” And seeing Ann’s disappointment: “Maybe next trip.”

      And then it was back to work on the interiors of the chambers, and the exteriors of a new wing. Arkady had suggested making the line of chambers the first of four, arranged in a square, and Nadia was going to do it; as Arkady pointed out, it would then be possible to roof the area enclosed by the square. “That’s where those magnesium beams will come in handy,” Nadia said. “If only we could make stronger glass panes …”

      They had finished two sides of the square, twelve chambers entirely done, when Ann and her team returned from Hebes. Everyone spent that evening looking at their videotapes. These showed the expedition’s rovers rolling over rocky plains; then ahead there appeared a break extending all the way across the screen, as if they were approaching the edge of the world. Strange little meter-high cliffs finally stopped the rovers, and the pictures bounced as one explorer got out and walked with helmet camera turned on.

      Then abruptly the shot was from the rim, a one-eighty pan shot of a canyon that was so much bigger than the sinkholes of Ganges Catena that it was hard to grasp. The walls of the far side of the chasm were just visible on the distant horizon. In fact they could see walls all the way around, for Hebes was an almost-enclosed chasm, a sunken ellipse about two hundred kilometers long and a hundred across. Ann’s party had come to the north rim in late afternoon, and the eastern curve of the wall was clearly visible, flooded by sunset light; out to the west the wall was just a low dark mark. The floor of the chasm was generally flat, with a central dip. “If you could float a dome over the chasm,” Ann said, “you’d have a nice big enclosure.”

      “You’re talking miracle domes, Ann,” Sax said. “That’s about ten thousand square kilometers.”

      “Well, it would make a good big enclosure. And then you could leave the rest of the planet alone.”

      “The weight of a dome would collapse the canyon walls.”

      “That’s why I said you’d have to float it.”

      Sax just shook his head.

      “It’s no more exotic than this space elevator you talk about.”

      “I want to live in a house located right where you took this video,” Nadia interrupted. “What a view!”

      “Just wait till you get up on one of the Tharsis volcanoes,” Ann said, irritated. “Then you’ll get a view.”

      There were little spats like that all the time now. It reminded Nadia unpleasantly of the last months on the Ares. Another example: Arkady and his crew sent down videos of Phobos, with his commentary: “The Stickney impact almost broke this rock in pieces, and it’s chondritic, almost twenty percent water, so a lot of the water outgassed on impact and filled the fracture system and froze in a whole system of ice veins.” Fascinating stuff, but all it did was cause an argument between Ann and Phyllis, their two top geologists, as to whether this was the real explanation for the ice. Phyllis even suggested shipping water down from Phobos, which was silly, even if their supplies were low and their demand increasing. Chernobyl took a lot of water, and the farmers were ready to start a little swamp in their biosphere; and Nadia wanted to install a swimming complex in one of the vaulted chambers, including a lap pool, three whirlpool baths, and a sauna. Each night people asked Nadia how it was coming along, because everyone was sick of washing with sponges and still being dusty, and of never really getting warm. They wanted a bath; in their old aquatic dolphin brains, down below the cerebrums, down where desires were primal and fierce,
