A
Molniya-M carrier rocket was used to launch the spacecraft. The launch occurred from
Site 1/5 at the
Baikonur Cosmodrome at 02:36:38 GMT on 17 June 1967. This mission was intended to be a Venus lander, similar in design to the Venera 4 spacecraft. The spacecraft became stranded in Earth orbit when its Blok VL, fourth stage (trans-interplanetary stage), failed to fire because the engine's turbopump had not been cooled prior to ignition, never departed its parking orbit, and was designated Kosmos 167. The spacecraft reentered on 25 June 1967. It would have received the next designation in the
Venera series, at the time
Venera 5. ==See also==
