Luna E-3 No.1, sometimes identified by NASA as Luna 1960A, was a Soviet spacecraft which was lost in a launch failure in 1960. It was a 279-kilogram (615 lb) Luna E-3 spacecraft, the first of two to be launched, both of which were lost in launch failures. It was intended to fly around the Moon on a circumlunar trajectory in order to image the surface of the Moon, including the far side. The E-3 spacecraft were similar in design to the E-2A which had been used for the earlier Luna 3 mission, however they carried higher resolution cameras, and were intended to make closer flybys.
Luna E-3 No.1 was launched at 15:06:45 UTC on 15 April 1960, atop a Luna 8K72 carrier rocket, flying from Site 1/5 at the Baikonur Cosmodrome. The Blok E upper stage cut off prematurely because pad crews had accidentally filled the RP-1 tank only halfway. As a result, the spacecraft failed to achieve orbit. Prior to the release of information about its mission, NASA correctly identified that it had been an attempted circumlunar imagery mission.
