Habitat

Definition

A habitat is an environment in which an organism, or group of organisms live in symbiosis.

Mars habitats

The environmental conditions on Mars are hostile for humans without life support systems; examples of the factors which make the surface of Mars uninhabitable include the thin, oxygen-poor atmosphere, the lack of easily available liquid water and the extremely cold climate. The habitat of any human visitor to Mars would have to be set of self-contained artificial environments such as buildings, rovers and space suits.

Terraforming has be suggested as a way of making the whole surface of Mars habitable. The more Mars is terraformed, thus increasing atmospheric pressure, the easier it is to built habitats and large domes, eventually huge domes spanning kilometers.

Transhab

Transhab a concept by NASA to produce inflatable habitats, producing more living space than traditional, solid habitats. This technology has been bought by Bigelow Aerospace, which is developing space hotels with this technology.
