The mere construction of the needed infrastructure presents a daunting set of technological and economic challenges. A space colony would set a precedent that would raise numerous socio-political questions. To date, no space colony has been set up. The most common objections to colonization include concerns that the commodification of the cosmos may be likely to enhance the interests of the already powerful, including major economic and military institutions enormous opportunity cost as compared to expending the same resources here on Earth exacerbation of pre-existing detrimental processes such as wars, economic inequality, and environmental degradation. 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 human-made), and the availability of additional resources in space that could enable expansion of human society. Many arguments have been made for and against space colonization.

Space colonization (also called space settlement or extraterrestrial colonization) is the hypothetical permanent settlement and exploitation of natural resources at celestial objects other than Earth. As such it is a form of human presence in space, beyond human spaceflight and operating space outposts.
