Luna E-3 No.2, sometimes identified by NASA as Luna 1960B, 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 second 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.
