Pictures of the Moon: Lunar Orbiter Image of Copernicus

         A portion of a Lunar Orbiter image of Copernicus crater taken in the mid 1960's. This image was very recently recovered from decades-old videotape, which had been destined for a landfill. It shows the central peaks and (collapsed) terraced walls of the crater in great detail. (USGS, NASA, apod070616)
