Lunar Orbiter

During 1966 through 1967, five Lunar Orbiter spacecrafts were launched, with the purpose of mapping the Moon's surface in preparation for the Apollo and Surveyor landings.

All five missions were successful. The first three Lunar Orbiters were mostly dedicated to obtaining detailed photographs of 20 areas preselected as possible future landing sites. Lunar Orbiters 4 and 5 concentrated on more general mapping, covering 99% of the lunar surface including most of the farside. Also, much was learned about the Moon's gravitational field.

After orbiting the Moon and returning hundreds of photographs, each Lunar Orbiter spacecraft was commanded to crash into the surface, destroying itself.
