One of the Block I vernier engines explodes after engine shutdown due to a failure of a liquid oxygen valve. This causes a violent yaw and role right a separation between the Block I and Block L stages. Due to this strong yaw and roll, the liquid oxygen turbo pump on the Block L engine failed, resulting in a loss of thrust.

Mission Details
2MV-2 n°1 (Venera 2)
Venera 2MV-2 n°1, also known as Sputnik 21 in the West, was a Soviet spacecraft, which was launched in 1962 as part of the Venera programme, and was intended to make a flyby of Venus. Due to a problem with the rocket which launched it, it failed to leave low Earth orbit, and reentered the atmosphere a few days later. It was the second Venera 2MV-2 spacecraft, both of which failed to leave Earth orbit.
