NASA has a gallery of art online of what the future was going be like, back from the 1970’s, what a wonderful vision – “A couple of space colony summer studies were conducted at NASA Ames in the 1970s. Colonies housing about 10,000 people were designed. A number of artistic renderings of the concepts were made. These have been converted to jpegs and are available as thumbnails, quarter page, full screen and publication quality images.” [via] – Link.
