Man on the Moon: The Voyages of the Apollo Astronauts by Andrew Chaikin (670 pages, Viking) is now available in bookstores. Chaikin's narrative takes the reader along with the astronauts as they encounter intense competition for flights, the rigors of training, and the incredible experience of journeying to another world and back. He also describes the conversion of test pilots into scientific observers, and their quests for geologic discoveries at Hadley, Descartes, and Taurus-Littrow. Finally, the astronauts express their thoughts, looking back 25 years later. Several of the astronauts have called this book the definitive account of their missions.
