Arthur C. Clarke was renowned for his science fiction, but his understanding of the subject was more than imagined.First published in 1951, this painstakingly-researched non-fiction book shows the depth of Clarke's expertise - he predicts the moon landings nearly two decades before they occurred, explores the potential use of satellites for communications more than ten years before Telstar 1 was put into orbit, and goes on to discuss the potential of space stations and long range orbital telescopes.Informed by interviews with the foremost scientists and engineers of the time, Clarke presents his thesis for how man will explore space . . . and the reader can measure his predictions against reality.'He was a great visionary, a brilliant science fiction writer and a great forecaster. He foresaw communications satellites, a nationwide network of computers, interplanetary travel; he said there would be a man on the moon by 1970, while I said 1980' - and he was right' Sir Patrick Moore
