Radar aboard NASA’s Magellan spacecraft has probed under the all-enveloping
Venusian clouds. Planetologist David Grinspoon explains to non-scientists the
incredible scientific advances this mission has made. Venus Revealed (Addison
Wesley, $27.50, ISBN 0 201 40655 1) is comparative planetology at its
finest. We should all worry whether Venus’s desertification and runaway
greenhouse effect might be catching. This book is compelling, clear,
comprehensive and highly recommended.
