Anyway, after the successful docking, the crew had been able to crawl through a docking tunnel and started moving into the Mission Module, their interplanetary home away from home.

As long as she didn’t think about the wisdom of taking apart the spacecraft in deep interplanetary space, it didn’t trouble York.

York let herself drift across the wardroom. She was light as a feather and invulnerable; it was like moving through a dream. The Mission Module was a lot roomier than the Apollo Command Module had been, of course. But she was learning to move around, to operate in that environment. She’d found she couldn’t move too quickly. If she did, she’d collide with the equipment, dislodging switches and maybe damaging gear. It just wasn’t a professional way to behave. She was learning to move slowly, with a kind of underwater grace.

It wasn’t a big deal. Microgravity was just a different environment; she’d learn to work within its constraints.

The wardroom, with its little plastic table and three belted chairs, was clean and empty, bright in the light of strip floods. The walls and floors weren’t solid; they were a gray mosaic of labeled storage drawers and feet restraints — loops of blue plastic — and there were handy little blue rectangles of Velcro everywhere. There were up-down visual cues, signs and lighting and color codes. Everything was obviously designed for zero G.

The whole thing had the feel of an airliner’s crew station, she thought; it was all kind of pleasing, compact, well designed, everything tucked away. Like a mobile home in space. Of course everything was still bright and new, every surface unmarked; it would be different after a few months’ occupancy. Much of the Mission Module’s equipment was still in stowage; the crew would spend the next few days hauling ass around the module, configuring it for its long flight.

The Waste Management Station was a little cubicle containing a commode, a military thing of steel and bolts and terse metal labels. She pulled across the screen, swiveled in the air, dropped her pants and shorts, and pulled herself down. Thigh bars, cushioned and heavy, swung across her legs to clamp her ass to the seat.

She pulled a hose out of the front of the commode; the hose would take her pee to a tank, for dumping in space later. The hose justified the Apollo-era nickname, “relief tube,” that the crews still used for the waste station. In a cupboard beside her there was a set of funnels, all color-coded to ensure they weren’t mixed up by the crew; hers, anyway, were of the distinctive female variety. The cupboard was already starting to stink a little, and the clear plastic of the funnels was turning yellow. Eighteen months of this.

She fitted the funnel to the hose, clamped it over her private parts, and opened the valve to the urine store.
