Space habitat (facility)

Not to be confused with Space habitat (settlement), Space colonization, or Habitation Module.

A space habitat (or habitation module) in a basic sense is any facility providing shelter and fulfilling habitational purposes in outer space. It is not to be confused with an extended space settlement, an arrangement of or infrastructure for multiple habitation facilities, in the sense of a space settlement. Space stations or theoretical extraterrestrial stations, such as a Moonbase or Mars habitat, include or are basic space habitats.^{[citation needed]}

The ISS was planned to get a now canceled dedicated Habitation Module.^[1]

Space tourism is expected to place dedicated habitats into space. The Axiom Orbital Segment will be a commercial habitation extension of the ISS for purposes such as tourism, but also commercial research.^[2]

Particularly inflatable space habitats have been in development. Based on the earlier NASA TransHab design,^[3] inflatable habitats have been developed and tested in orbit by the now inactive company Bigelow Aerospace.^[4]

Definition

The International Astronautical Federation has differentiated space habitats to space settlements and space infrastructure the following way:

• Habitat: pressurized volume(s) within which humans live and work, including relevant facilities for life support.
• Settlement: group of permanently inhabited habitats installed near each other, possibly interconnected.
• Infrastructure: set of constructed elements supporting habitats and/or settlements such as (and not limited to): power plant, water plant, greenhouse and waste management facilities, communication facilities, transportation facilities, EVAs, roads, spaceport, research platforms, and so on.^[5]

Extraterrestrial surface habitat

Main articles: Lunar habitation, Moonbase, Lunar module, and Mars habitat

The only extraterrestrial surface habitats that sofar have been erected were the temporary Apollo Lunar Modules, such as Eagle of Tranquility Base, the very first.
