''The High Frontier: Human Colonies in Space'' is a 1976 book by Gerard K. O'Neill, a road map for what the United States might do in outer space after the Apollo program, the drive to place a man on the Moon. It envisions large manned habitats in the Earth-Moon system, especially near stable Lagrangian points. Three designs are proposed: Island one (a modified Bernal sphere), Island two (a Stanford torus), and Island 3, two O'Neill cylinders. These would be constructed using raw materials from the lunar surface launched into space using a mass driver and from near-Earth asteroids. The habitats were to spin for simulated gravity and be illuminated and powered by the sun. Solar power satellites were proposed as a possible industry to support the habitats. The book won the 1977 Phi Beta Kappa Award in Science.〔 〕 ==Illustrations== The book featured impressions of life in outer space by a number of artists including Don Davis, Rick Guidice, and Chesley Bonestell.
