Rain Of Iron And Ice: The Very Real Threat Of Comet And Asteroid Bombardment (Paperback)
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.
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.
