The new Project Apollo Archive on Flickr contains some stunning gems amidst many, many photos of the lunar surface.
Edwin "Buzz" Aldrin, the second man to set foot on the moon, photographed in the Apollo 11 spacecraft, July 1969.
The third EVA of Apollo 17 and the last of the Apollo program, December 13, 1972. No one has set foot on the moon since.
This photograph from Apollo 17 demonstrates quite neatly the lack of colour on the lunar surface. December 1972.
