Mar. 21, 1964: Launch
This fourth Soviet attempt to achieve a soft-landing on the Moon failed to reach an intermediate orbit around Earth.
During the boost phase, the launcher's third-stage engine's main liquid oxygen valve failed to open when the valve rod broke off. As a result, the third-stage engine never reached full thrust and eventually cut off prematurely at T+489 seconds. The spacecraft never reached Earth orbit.
