This identical twin craft to Venera 4 failed to leave Earth orbit when its Blok L transinterplanetary stage failed to fire, apparently because the engine's turbo pump had not been cooled prior to ignition.

The spacecraft remained stranded in Earth orbit and reentered Earth's atmosphere on 25 June 1967.
