Mission details:

• Luna 1964B was the fifth Soviet attempt to land an unmanned spacecraft on the Moon.
• Soft-landing attempted launch, but at T+340 sec the launcher's control system failed and the engine of Stage 3 cut off prematurely due to loss of a section of the circuit between BOZ's storage battery and a DC transformer. The assembly tumbled before re-entry, where it broke up as it hit the atmosphere.
