Zenit Launch Failures

This table lists all occasions where a Zenit satellite failed to reach orbit through some fault of the launch vehicle.

Where the launch vehicle was destroyed early in the mission, the Zenit was likely destroyed too. In at least one instance where the failure occurred at high altitude, the cabin separated and was was recovered.

Cosmos (Zenit-2 11Ф61 № 1)              
1961 Dec 11, 09:39 UTC
Baikonur Cosmodrome
Vostok 8K72K
Protoype recoverable photo-reconnaissance satellite - failed to reach orbit when the upper stage cutoff prematurely and the spacecraft destruct system fired at T+407 seconds. The descent module reportedly landed in Siberia but was never found.
