19 Facts About Space colonization

Space colonization colonies are generally conceived as organizational and material structures that have to provide for nearly all the needs of larger numbers of humans, in an environment out in space that is very hostile to human life and inaccessible for maintenance and supply from Earth.

The location of Space colonization can be on a physical body planet, dwarf planet, natural satellite, or asteroid or orbiting one.

Space colonization suggests that it would be better to construct such a base on an inner planet, such as Venus: inner planets have higher orbital velocities, making the transfer time to any specific asteroid shorter, and orbit the Sun faster, so that the launch windows to the asteroid are more frequent.

Above concepts appear limited to high, but still sub-relativistic speeds, due to fundamental energy and reaction mass considerations, and all would entail trip times which might be enabled by space colonization technology, permitting self-contained habitats with lifetimes of decades to centuries.

Thus, even if interstellar travel at near relativistic speeds is never feasible, the development of space colonization could allow human expansion beyond the Solar System without requiring technological advances that cannot yet be reasonably foreseen.

Distances between galaxies are on the order of a million times farther than those between the stars, and thus intergalactic Space colonization would involve voyages of millions of years via special self-sustaining methods.

Space colonization activity is legally based on the Outer Space colonization Treaty, the main international treaty.

The Magna Carta of Space presented by William A Hyman in 1966 framed outer space explicitly not as terra nullius but as res communis, which subsequently influenced the work of the United Nations Committee on the Peaceful Uses of Outer Space.

Primary argument calling for space colonization is the long-term survival of human civilization and terrestrial life.

An argument for space colonization is to mitigate proposed impacts of overpopulation of Earth, such as resource depletion.

Advocates for space colonization cite a presumed innate human drive to explore and discover, and call it a quality at the core of progress and thriving civilizations.

Nick Bostrom has argued that from a utilitarian perspective, space colonization should be a chief goal as it would enable a very large population to live for a very long period of time, which would produce an enormous amount of utility (or happiness).

Space colonization has been seen as a relief to the problem of human overpopulation as early as 1758, and listed as one of Stephen Hawking's reasons for pursuing space exploration.

The issues of human dignity, morality, philosophy, culture, bioethics, and the threat of megalomaniac leaders in these new "societies" would all have to be addressed in order for space colonization to meet the psychological and social needs of people living in isolated colonies.

Corollary to the Fermi paradox—"nobody else is doing it"—is the argument that, because no evidence of alien Space colonization technology exists, it is statistically unlikely to even be possible to use that same level of technology ourselves.

Space colonization has been discussed as postcolonial continuation of imperialism and colonialism, calling for decolonization instead of colonization.

Critics argue that the present politico-legal regimes and their philosophic grounding advantage imperialist development of space and that key decisionmakers in space colonization are often wealthy elites affiliated with private corporations, and that space colonization would primarily appeal to their peers rather than ordinary citizens.

Guiana Space Centre has been the sight of anti-colonial protests, connecting colonization as an issue on Earth and in space.

NASA found that isolation in closed environments aboard the International Space colonization Station led to depression, sleep disorders, and diminished personal interactions, likely due to confined spaces and the monotony and boredom of long space flight.
