Questions tagged [space-station]

A space station (or orbital station) is a spacecraft capable of supporting a crew, which is designed to remain in space (most commonly in low Earth orbit) for an extended period of time. For questions about specific space stations (e.g. the ISS, MIR, Salyut 1-7, Tiangong or Skylab), please use corresponding tags.
