Luna 12 was launched to complete the mission that Luna 11 had failed to accomplish: take high-resolution photos of the Moon's surface from lunar orbit.

Luna 12 successfully reached the Moon on 25 October 1966 and entered a 133 x 1,200-kilometer orbit.

The Soviet press released the first photos taken of the surface on 29 October, pictures that showed the Sea of Rains and the Aristarchus crater. Resolution was as high as 15 to 20 meters. Film was developed, fixed, dried automatically, and scanned for transmission to Earth. No further photos were ever released.

After completing its main imaging mission, Luna 12 was put into a spin-stabilized roll to carry out its scientific mission, which was fulfilled quite successfully. Contact was finally lost on 19 January 1967 after 302 communications sessions.
