Luna E-6 No.8, sometimes identified by NASA as Luna 1965A,[1] was a Soviet spacecraft which was lost in a launch failure in 1965. It was a 1,422-kilogram (3,135 lb) Luna E-6 spacecraft,[2] the seventh of twelve to be launched,[3] It was intended to be the first spacecraft to perform a soft landing on the Moon, a goal which would eventually be accomplished by the final E-6 spacecraft, Luna 9.

Luna E-6 No.8 was launched on 10 April 1965, atop a Molniya-L 8K78L carrier rocket, flying from Site 1/5 at the Baikonur Cosmodrome.[4] During third stage flight, a nitrogen pipeline in the oxidiser tank depressurised, which caused a loss of oxidiser flow to the engine and resulted in the engine cutting off. The spacecraft failed to achieve orbit, and the spacecraft disintegrated on reentry.[5] Prior to the release of information about its mission, NASA correctly identified that it had been an attempt to land a spacecraft on the Moon.[1]
