David Harland here initiates a series of books on NASA’s Moon Program of the 1960s and early 1970s. Presented chronologically, ‘NASA’s Moon Program – The Early Years’ will outline the Mercury and Gemini manned missions, the unmanned lunar probes and the Apollo missions leading up to Apollo 11, covering that mission only as a postscript. ‘The First Men on the Moon – The Story of Apollo 11,’ released in 2006 is devoted solely to that mission. ‘Apollo – The Definitive Sourcebook,’ published in 2006, covered all the missions, including the unmanned tests, in an encyclopedic style which included many facts and figures. ‘Exploring the Moon – The Apollo Expeditions,’ published in 1999, focused on the final three Apollo missions, and covered only their activities on the lunar surface.
