All three volumes sold as a combined set for a one-time purchase! This comprehensive three-volume set takes you on an incomparable journey of our closest celestial neighbor. Not since the golden age of 19th-century lunar guidebooks has one author managed to cover the Moon in such detail as this all-in-one handbook. Volume 1 begins with a section on the Moon’s place in human history, mythology and lore, before gravitating closer to the Moon itself through scientific sections on the Earth-Moon system, lunar motions and cycles. Following these are technical chapters on how to purchase, use and care for lunar observing and photography equipment. Techniques for observing the Moon (both with the naked eye and optical instruments) are detailed as the reader approaches the Moon’s surface on this visual tour-de-force. A close-up exploration of the Moon is the result. The “crater-hop” chapters in Volumes 1 and 2 discuss the physical aspects of the Moon’s features, offering brief biographical information on the person for whom the feature is named, as well as how each individual was involved in the development of science and selenography from ancient to modern times. Volume 3 contains a plethora of useful appendices that cover a range of topics, from catalogues of lunar features such as nearside lunar domes to a comprehensive list of publishers and observing organizations. Luna Cognita goes far beyond any recent work in both breadth and depth of coverage on the Moon. Written in an accessible, engaging manner for readers of all backgrounds and levels of expertise, this handbook is thus an invaluable resource for anybody who looks up at the glowing sphere in the night sky and wants to learn more about the “Known Moon.”

The only work to date to collect data gathered during the American and Soviet missions in an accessible and complete reference of current scientific and technical information about the Moon.

Volume 60 of Reviews in Mineralogy and Geochemistry assesses the current state of knowledge of lunar geoscience, given the data sets provided by missions of the 1990's, and lists remaining key questions as well as new ones for future exploration to address. It documents how a planet or moon other than the world on which we live can be studied and understood in light of integrated suites of specific kinds of information. The Moon is the only body other than Earth for which we have material samples of known geologic context for study. This volume seeks to show how the different kinds of information gained about the Moon relate to each other and also to learn from this experience, thus allowing more efficient planning for the exploration of other worlds.

Structure of the Moon's Surface focuses on the importance of certain features of the Moon's surface that have frequently been disregarded in the past, largely because of lack of knowledge of them. Topics covered include the librations of the Moon; height determinations of the points on the lunar surface; luminous intensity and luminescence of the lunar rocks; the color of moonlight and composition of the Moon's surface; and the Moon's temperature and atmosphere. This book is comprised of 14 chapters and begins with a review of important physical problems associated with the Moon, including its motion and figure as well as the luminous intensity and luminescence of its rocks. The following chapters discuss the polarization of light reflected by the Moon; the problem of the Moon's atmosphere; the probable nature of the Moon's surface; and changes occurring on the Moon. The Moon's ray and grid systems, lattice patterns, rilles and faults, and distribution and frequency of craters are also considered. The final chapter is devoted to the origin of the Moon's surface. This monograph will be of use to both professional and amateur lunar astronomers.
