In-space colonies

Space.com today has an article and the infographic shown below about the in-space colony concepts developed by Princeton Prof. Gerard K. O’Neill and his collaborators during the 1970s and 80s. (They got some NASA grants but it’s a huge exaggeration to say NASA had a “plan to put thousands of people in Space Colonies”.)

See the Space Studies Institute for more details and the HobbySpace Art section for links to more space colony artwork.
