Informationen zum Autor John S. Lewis, author of Rain of Iron and Ice, is professor of planetary sciences and codirector of the Space Engineering Research Center at the University of Arizona-Tucson. He has chaired international conferences on space resources and is a globally recognized expert on the subject. Klappentext Recent scientific study by geologists and planetary scientists has turned up dramatic evidence that not only have massive solid bodies from space hit the earth! moon! and planets in the geologic and historic past! but they are likely to hit again! with cataclysmic consequences. This book details the continuing search of such impacts and its implications for the future of life on earth. Zusammenfassung Rain of Iron and Ice shows us the unmistakable evidence?from spaceprobe flybys of the planets to the scars on our own Earth?of cataclysmic comet and asteroid impacts. By comparing what we know about the earth's geology and paleontology with the ages of the other planets and moons in our solar system, Lewis makes the strongest case yet for sudden, dramatic extinctions and assesses the risks to planet Earth.
