Luna E-1 No.3,[1] sometimes identified by NASA as Luna 1958C,[2] was a Soviet spacecraft which was lost in a launch failure in 1958. It was a 361-kilogram (796 lb) Luna E-1 spacecraft, the third of four to be launched,[3] all of which were involved in launch failures.[4] It was intended to impact the surface of the Moon, and in doing so become the first man-made object to reach its surface.

The spacecraft was intended to release 1 kilogram (2.2 lb) of sodium, in order to create a cloud of the metal which could be observed from Earth, allowing the spacecraft to be tracked.[5] Prior to the release of information about its mission, NASA correctly identified that it had been an attempted Lunar impact mission.[2]

Luna E-1 No.3 was launched on 4 December 1958 atop a Luna 8K72 carrier rocket,[4] flying from Site 1/5 at the Baikonur Cosmodrome.[1] Two hundred and forty five seconds into the flight, a hydrogen peroxide pump seized up due to loss of lubrication, which caused the rocket's core stage engines to fail.[4]
