Ah - Belter's are what we call the people who live out in the Belt. Or beyond it. It's an asteroid belt, between Mars and Jupiter - though a lot of Belters actually live in the Jovian system, some in the Saturn system around Titan, for example.

There ain't a planet or moon or rock in the solar system that can live without domes or some other structure - save Earth. Earth's the only one with a habitable atmosphere. The rest of us gotta get by with what air and water we bring with us. Like this place.

This ain't a ship. Trust me, I'd be a hell of a lot happier if it was. But this is a station, which means she ain't goin' anywhere, any time soon. She reminds me a bit of Tycho, though. It ain't completely unfamiliar. Though no station I ever heard of would put windows like the ones we got on the observation deck.
