bacteria, keep moist, and wait. And hope. Microbes liked free carbon, using it with water to frame elaborate molecules. She and Viktor had doled it out for years under the first, small dome before even trying to grow anything. The Book of Genesis got it all done in six days, but mere humans took longer.
She hit the marker they had laid out—a rock—and turned, pointing off-camera. “And now— ta’daah! —we have a surprise. The first Martian swimming pool.”
Okay, no swimming pools in Genesis — but it’s a step.
“I’m going for my first swim—now.” She shucked off her blue jumpsuit to reveal a red bikini. Her arms and legs were muscular, breasts midsize, skin pale, not too many wrinkles. Not really a babe, no, but she still got mash notes from middle-aged guys, somehow leaking through the e-mail filters.
Hey , we’re looking for market share here! She grinned, turned, and dove into the lapping clear water. Surfaced, gasped—she wasn’t faking, this really was her first swim in a quarter century—and laughed with sheer pleasure (not in the script). Went into a breaststroke, feeling the tug and flex of muscle, and something inexpressible and simple burst in her. Fun, yes — not nearly enough fun on Mars.
Or water. They had moved from the original base camp about eighteen years before. Once Earthside had shipped enough gear to build a real water-retrieval system, and a big nuke generator to run it, there seemed no point in not moving the hab and other structures—mostly light and portable—to the ice hills.
Mars was in some ways an upside-down world. On Earth one would look for water in the low spots, stream channels. Here in Gusev water lay waiting in the hilly hummocks, termed by geologists “pingos.” When water froze beneath blown dust, it thrust up as it expanded, making low hills of a few hundred meters. She recalled how Marc and Raoul had found the first ice, their drill bit steaming as ice sublimed into fog. Now Marc was a big vid star and Raoul ran Axelrod’s solar energy grid on the moon. Time…
She stopped at the pool edge, flipped out, and sprang to her feet— thanks, 0.38 g! “The first swim on Mars, and you saw it.” Planned this shot a year ago, when I ordered the bikini. She donned a blue terry-cloth bathrobe; the dryness made the air feel decidedly chilly. “In case you’re wondering, swimming doesn’t feel any different here. That’s because the water you displace makes you float—we’re mostly made of water, so the effect compensates. It doesn’t matter much what the local gravity is.”
Okay, slipped in some science while their guard was down.
“Behind all this is our improved water-harvesting system.” She pointed out the dome walls, where pipes stretched away toward a squat inflated building. “Robotic, nuclear-powered. It warms up the giant ice sheets below us, pumps water to the surface. Took nine years to build—whoosh! Thank you, engineers.”
What did the water mean? She envisioned life on a tiny fraction of Mars with plentiful water—no longer a cold, dusty desert. Under a pressurized dome the greenhouse effect raised the temperature to something livable. Link domes, blow up bigger ones, and you have a colony. They could grow crops big-time. Red Kansas…
A gout of steam hissed from a release value, wreathing her in a moist, rotten-egg smell. Andy had put the finishing touches on the deep thermal system, spreading the upwelling steam and hot water into a pipe system two meters below the dome floor. Their nuke generators ran the system, but most of the energy came for free from the magma lode kilometers below. Once the geologists—“areologists” when on Mars, the purists said—had drilled clean through the pingos and reached the magma, the upwelling heat melted the ice layers. Ducted upward, it made possible the eight domes they now ran, rich in moist air. Soon they would start linking them all. She smiled as she thought about strolling along
