With the success of the Apollo missions, NASA turned its attention to the prospect of off-planet colonies. The space agency conducted its “summer studies” at NASA Ames in 1975, allowing experts and artists to share their visions of what space colonies could look like. The resulting concepts were bold, including space habitats in which 10,000 people would “work, raise families, and live normal human lives,” according to A from several NASA studies. The wheel-shaped habitats would simulate gravity, allowing for traditional houses, monorails, trees, grasses, water bodies and agriculture. It was hoped that some habitats might appear as early as the 1990s, but these ideas, while wonderful, were a little too technologically advanced.
