Space colonization (or extraterrestrial colonization) is the settlement or colonization of outer space and astronomical bodies. The concept in its broad sense has been applied to any permanent human presence in space, such as a space habitat or other extraterrestrial settlements . [ 2 ]

A space settlement (also called a space habitat, spacestead, space city or space colony) is a settlement in outer space, sustaining more extensively habitation facilities in space than a general space station or spacecraft.
Space exploration also gives scientists the ability to perform experiments in other settings and expand humanity's knowledge. [67] Another claim is that space exploration is a necessity to humankind and that staying on Earth will eventually lead to extinction. Some of the reasons are lack of natural resources, comets, nuclear war, and worldwide ...
Most colonization concepts focus on settling, but colonization is a broader ethical concept, [56] which international space law has limited, [57] and national space programs have avoided, [58] instead focusing on human mission to Mars for exploring the planet. The settlement of Mars would require the migration of humans to the planet, the ...
An O'Neill cylinder (also called an O'Neill colony, or Island Three) is a space settlement concept proposed by American physicist Gerard K. O'Neill in his 1976 book The High Frontier: Human Colonies in Space. [1] O'Neill proposed the colonization of space for the 21st century, using materials extracted from the Moon and later from asteroids. [2]
A growing number of scientists think human colonization of the solar system is inevitable. It's not clear when we'll see humans walking around on the moon or Mars, but it's coming, and it's going ...
Colonization of Mars differs from the crewed Mars exploration missions currently pursued by public space agencies, as they aim to land humans for exploration. [6] [7]The terminology used to refer a potential human presence on Mars has been scrutinized since at least the 2010s, [4] with space colonization in general since the 1977, as by Carl Sagan, who preferred to refer to settlements in ...
Artist's conception of a space habitat called the Stanford torus, by Don Davis. O'Neill's first published paper on the subject, "The Colonization of Space", appeared in the magazine Physics Today in September 1974. A number of people who later became leaders of the L5 Society got their first exposure to the idea from this article.
