During this third attempt at a circumlunar mission, the Proton rocket's second stage engine spuriously shut down at T+194.64 seconds due to an erroneous signal from the payload.

The emergency rescue system was activated, and the 7K-L1 capsule was later recovered about 520 kilometers from the launch pad.
