Space colonization (or extraterrestrial colonization) is the colonization of outer space and astronomical bodies. As such it is a process of occupation or control for exploitation and possibly settlement, in contrast to mere space travel and space exploration .

A space settlement (also called a space habitat, space stead, 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 ...
An O'Neill cylinder (also called an O'Neill colony) 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 ...
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 ...
The colonization of Titan is not likely to happen for many decades or even within the current century. NASA is focused on the moon and Mars as destinations to send astronauts.
Colonization of the Moon has been imagined as early as the first half of the 17th century by John Wilkins in A Discourse Concerning a New Planet. [1] [2]In the early Space Age the USSR and the US engaged in dropping pennants [3] and raising flags on the Moon, like this Lunar Flag Assembly of 1969, but agreed internationally in 1967 with the Outer Space Treaty to not lay any claims over the ...
