To a rocky moon - A geologist's history of lunar explorationA detailed historical account is given of lunar exploration by a scientist who had been involved in the field before and after, as well as during, the period of the Apollo moon landings. Attention is given to the ways in which the initial, robotic lunar-probe landings added crucially to the store of knowledge on which planning for the manned landings relied, and the process by which lunar science became increasingly geological. The six successful manned landings and their scientific determinations are discussed.
