caption_attribution_description: English: This unique photographic angle, featuring the International Space Station's Cupola and crew activity inside it, other hardware belonging to the station, city lights on Earth and airglow was captured by one of the Expedition 28 crew members. The major urban area on the coast is Brisbane, Australia. The station was passing over an area southwest of Canberra.
context_page_description: A space habitat is more than a bare-bones space station, in that it is intended as a permanent settlement or green habitat rather than as a simple way-station or other specialized facility. No space habitat has been constructed yet, but many design concepts, with varying degrees of realism, have come both from engineers and from science-fiction authors.
  The term space habitat sometimes includes more broadly colonies built on or in a body other than Earth—such as the Moon, Mars or an asteroid.
context_section_description: The requirements for a space habitat are many. They would have to provide all the material needs for hundreds or thousands of humans, in an environment out in space that is very hostile to human life.
