Publishers Weekly

This volume informally yet comprehensively surveys meteorites (which reach the surface of the earth) and meteors (which don't)-their origins, types, consequences and prospects for influencing future events. Author Lewis, codirector for science at a NASA/University of Arizona research center, is passionate and upbeat on the topic. Addressing the general reader, he recounts apt anecdotes in historical context while outlining a commonsensical framework for understanding the scientific scope and nature of the matter that comes to earth from space. Early chapters describe legendary meteorite falls. Subsequent chapters consider, for example, new knowledge from studies of nuclear explosions, cratering on Mars and Mercury, atmospheric effects on Venus and biological signatures of impacts in earth fossil records. Very interesting are results of computer simulations based on the accumulated discoveries, which project what we can expect from future encounters. Overall, Lewis presents an impressively readable and informative digest of current knowledge on the subject. (Feb.)
