The United States launched five uncrewed spacecraft to the Moon between 1966 and 1967 to map the lunar surface for Apollo landing site selection. These missions aimed to provide detailed images of potential crewed landing areas before sending astronauts. All five missions succeeded in mapping ninety-nine percent of the lunar surface with resolutions better than one meter.
Lunar Orbiter 1 launched on the 10th of August 1966, and imaged the Moon from August 18 through 29 that same year. It impacted the lunar surface on the 29th of October 1966 after completing its survey mission. This mission also captured the first pictures of Earth as a whole starting with an Earth-rise over the lunar surface in August 1966.
All five missions returned photography covering ninety-nine percent of the Moon's surface. Altogether they sent back two thousand one hundred eighty high resolution frames plus eight hundred eighty-two medium resolution frames. Each spacecraft was eventually commanded to crash into the Moon to avoid becoming navigational hazards for future Apollo flights.
Kodak created an onboard film development process that scanned images from seventy millimeter film for transmission back to Earth. The camera used two lenses simultaneously exposing wide-angle and high-resolution images onto a single roll of sixty-five millimeter Kodak Bimat film. An eighty millimeter F 2.8 Xenotar lens manufactured by Schneider Kreuznach handled medium resolution shots while a six hundred ten millimeter F 5.6 Panoramic lens made by Pacific Optical Company captured high detail views.
Lunar Orbiter 5 captured the first full picture of the entire Earth on the 8th of August 1967. A second photo of the complete globe followed on the 10th of November 1967. This mission also completed far side coverage while acquiring medium and high resolution images of thirty-six preselected areas.
