A space habitat (or habitation module) in a basic sense is any facility providing shelter and fulfilling habitational purposes in outer space.
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.
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] The International Astronautical Federation has differentiated space habitats to space settlements and space infrastructure the following way: 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.
