People dreamed of cosmic exploration, winged spaceships and lunar voyages; space stations and robot astronauts, long before it actually happened. This book traces the emergence of space travel in the popular mind, its expression in science fiction, and its influence on national space programs. Space exploration dramatically illustrates the power of imagination. The author shows how that power inspired people to attempt what they once deemed impossible. In a mere half-century since the launch of the first Earth orbiting satellite in 1957, humans achieved much of what they had once only read about in the fiction of Jules Verne and H.G. Wells and the nonfiction of Willy Ley. Reaching these goals, however, required broad-based support, and the author examines how advocates employed familiar metaphors to excite interest (promising, for example, that space exploration would recreate the American frontier experience) and prepare the public for daring missions into space. When unexpected realities and harsh obstacles threatened their progress, the space community intensified efforts to make their wildest dreams come true. This work remains relevant given contemporary questions about future plans at NASA. Fully revised and updated since its original publication in 1997, it includes a reworked introduction and conclusion and new chapters on robotics and space commerce.
