As termed by Life magazine, "The picture of the Century", was taken on 22 November 1966 by the Lunar Orbiter 2 spacecraft. The Lunar Orbiter Program (1966-7) was a series of unmanned missions to help with the selection of landing sites for the later Apollo missions, they provided the first photographic maps from a lunar orbit.
Taking its name from the great astronomer Nicolaus Copernicus (1473-1543), the 93km crater is one of the Moon's most prominent features and is easily visible with binoculars. Formed over 1 billion years ago by an impact from a meteor, the crater features a central complex of peaks surrounded by smooth flats bordered by a crater wall 3.8km high. It was considered as a landing site for the cancelled Apollo 20 mission since it was then considered volcanic in origin.
