This was the second of three Venus spacecraft launched by the Soviets in 1962.

Like its predecessor launched in August 1962 (also a Venus impact probe), the spacecraft never left parking orbit around Earth because of a malfunction in the Blok L upper stage designed to send the probe out of Earth orbit toward Venus.

Evidently, the valve that controlled the delivery of fuel into the combustion chamber of the Blok L engine (the S1.5400) never opened. As a result, the engine never fired. The payload decayed within five days of launch.

Fast Facts
2MV-1/2 Facts This was the Soviet Union's 15th interplanetary mission.

Only three of the 11 interplanetary missions launched by both nations in 1962 were successful. Of those, only Mariner 2 was a complete success.

On this mission, the final stage failed to fire and send it from Earth orbit to Venus.
