This was the second Soviet attempt at a robotic circumlunar mission. On this launch, one of the four second-stage engines of the Proton rocket failed to ignite at T+125.5 seconds due to a break in the engine nozzle.

The wayward booster was then destroyed on command from the ground at T+129.9 seconds.
