Man And The Planets

Habitable Planets for Man examines and estimates the probabilities of finding planets habitable to man, where they might be found, and the number there may be in our own galaxy. The author presents in detail the characteristics of a planet that can provide an acceptable environment for humankind, itemizes the stars nearest the earth most likely to possess habitable planets, and discusses how to search for habitable planets. Interestingly for our time, he also gives an appraisal of the earth as a planet and describes how its habitability would be changed if some of its basic properties were altered. This is a reprint of an edition originally published in 1964.

The message had seemed simple, yet it was more complex than Don could have imagined. He was being called from Earth to an alien world for reasons unknown¾save only that his life depended on it. But setting out for Mars and getting there in good shape turned out to be a lot more complicated than Don ever would have guessed possible. It was trouble enough being inexplicably hounded by Earth's secret police. But when he was hijacked by Venusian rebels, Don suddenly realized that he was trapped in the center of a war between worlds that could change the fate of the Solar System forever!

"Habitable Planets for Man" examines and estimates the probabilities of finding planets habitable to human beings, where they might be found, and the number there may be in our own galaxy. The author presents in detail the characteristics of a planet that can provide an acceptable environment for humankind, itemizes the stars nearest the earth most likely to possess habitable planets, and discusses how to search for habitable planets. Interestingly for our time, he also gives an appraisal of the earth as a planet and describes how its habitability would be changed if some of its basic properties were altered. "Habitable Planets for Man" was published at the height of the space race, a few years before the first moon landing, when it was assumed that in the not-too-distant future human beings "will be able to travel the vast distances to other stars." More than forty years after its initial publication, and to celebrate RAND's 60th Anniversary, RAND is proud to bring this classic work back into print in paperback and digital formats.
