Unlike the Moon, this volume only took a little more than 4 years in the making, but like the Moon, it has gone through numerous changes. However, through it all, the editors of this volume have expertly coordinated the numerous authors and extensive subject matter into a comprehensive review in which the reader is now easily re-introduced to a "forgotten friend," the Moon. Their hard work and unwaivering dedication has made this volume a reality! My thanks goes out to them!

A high level of activity associated with the exploration of Mars and a resurgence of activity associated with the anticipated return to the Moon have captured the imagination of much of the planetary science community and the public, alike. The present level of involvement and enthusiasm for studies of the Moon are high, perhaps as high as they have been since shortly after the end of the U.S. Apollo and Soviet Luna programs. The very successful orbital missions of the 1990s, Clementine and Lunar Prospector, have provided key mineralogical, geochemical, and geophysical data sets that will take many years to fully process and digest. These new data sets must be integrated carefully with information gained from three preceding decades of study of lunar samples and older, less complete, remotely sensed data sets. Although there have been no new lunar sample-return missions since Apollo and Luna, new samples are available in the form of meteorites, recognized to be pieces of the Moon delivered to Earth by impact and gravitational forces. These, too, play a role in improved
