Space Habitat

Space Habitat and Space City

A space habitat (also called a space colony, space settlement, orbital habitat, orbital settlement or orbital colony) 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.

 

Space Colonization

Many arguments have been made for and against space colonization.

The two most common in favor of colonization are survival of human civilization and the biosphere in the event of a planetary-scale disaster (natural or man-made), and the availability of additional resources in space that could enable expansion of human society.

No space colonies have been built so far. Currently, the building of a space colony would present a set of huge technological and economic challenges. Space settlements would have to provide for nearly all (or all) the material needs of hundreds or thousands of humans, in an environment out in space that is very hostile to human life.

They would involve technologies, such as controlled ecological life support systems, that have yet to be developed in any meaningful way. They would also have to deal with the as-yet unknown issue of how humans would behave and thrive in such places long-term.

There are yet no plans for building space colonies by any large-scale organization, either government or private. However, many proposals, speculations, and designs for space settlements have been made through the years, and a considerable number of space colonization advocates and groups are active.
