• Luna 1964A (E-6 series) was the fourth Soviet attempt to land an unmanned spacecraft on the Moon.
• Soft-landing attempt, but at T+290 sec the vernier chambers of Stage 3's 8D715P engine failed to reach their full thrust level - a LOX valve did not open - a rod in the oxidiser valve's pyrotechnic unit broke. At T+486.8s the main chambers of the 8D715P engine cut off prematurely. re-entry and destruction followed over the Pacific Ocean.
