Stunning Space Colony Concept Art from the 1970sAugust 13th, 2013
Three space colony summer studies were conducted at NASA Ames in the 1970s. The three studies looked at the toroidal colonies with a population of up to 10,000; the Bernal Sphere with a spherical living area and again with a population of up to 10,000; and cylindrical colonies for populations of over one million. A number of artistic renderings of the concepts were made, shown in the gallery below. The large image above is a cutaway view of a Bernal Sphere created by Rick Guidice.
