|Alternate Names||Unnamed Venera, 1967-063A, 02852|
This spacecraft was designed to drop a probe through Venus' atmosphere like its twin, Venera 4.
None. The rocket engine that was to propel it from Earth orbit to Venus failed to fire, and the spacecraft system re-entered the atmosphere after circling Earth for eight days.
June 17, 1967: Launch
June 25, 1967: Re-Entered Earth's Atmosphere
This identical twin craft to Venera 4 failed to leave Earth orbit when its Blok L trans-interplanetary 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 June 25, 1967.
