Misplaced Lunar Orbiter Imagery Found After 46 Years
Hadley Rille
Lunar Orbiter Image Recovery Project

High resolution imagery from the Lunar Orbiter program, forgotten for nearly 50 years, has been retrieved from original data tapes.
The five Lunar Orbiter missions, flown between 1966 and 1967, were rather heavily documented. This extensive documentation has helped us at the Lunar Orbiter Image Recovery Project (LOIRP) to locate images on the original analog data tapes and retrieve them at a resolution that was impossible in the 1960s.

While the Lunar Orbiter program was methodical in documenting everything, every now and then imagery slipped through the crack. Often times the misplaced images are unremarkable and incomplete. However, in this case, we have found complete high resolution imagery of a location close to the Apollo 15 landing site at Hadley Rille. The imagery we have uncovered is number 5105 taken by Lunar Orbiter V in 1967.
