Having written on the space shuttle and the Russian space station Mir, David Harland now ventures further back into the history of space exploration with this book. Exploring the Moon is a welcome addition to the plethora of books regarding the Apollo Program, providing an on-the-surface narrative and and scientific analysis of the missions reminiscient of the Apollo Lunar Surface Journal. After a section on the unmanned probes in the 1960's (Ranger, Lunar Orbiter, and Surveyor), he moves on to the Apollo flights, outlining the moonwalks on Apollo 11, 12, and 14, and then spends the bulk of the book outlining the Apollo "J" missions-Apollo 15, 16, and 17, which featured advanced life support systems in the lunar module and the astronauts' backpacks, an extended three days on the lunar surface, and a four-wheeled battery-powered buggy known as the Lunar Roving Vehicle. While most books focus on the technology that got America to the moon, few jave focused on the subsequent excursions of the spacesuit-clad astronauts on the lunar surface. This book does so magnificently, combining technical commentary with the words the astronauts spoke and the photographs they took. With the bonanza of lunar information provided by the last three Apollo missions, you will wonder why we felt inclined to cancel the Apollo missions 18, 19, and 20. Overall, I think this book covers lunar science and geology superbly, is a great adventure story, and a unique contribution to the studies of lunar science and planetary geology.
