NASA Finds Lost Spacecraft on Dark Side of the Moon : Discovery Channel: NASA scientists have found the crash site, pictured above, of a spacecraft set into orbit during the early 60s. This one–thankfully–is not crawling with Decepticons. They believe it is the missing Lunar Orbiter 2 which disappeared back in 1967 during a passage over the far side of the moon, when the craft went out of telescope and radio range.
