Mars 2MV-3 - Mars 1962b

Launch date: 04 November 1962
Nation: USSR
Outcome: failure

Wikipedia - "The spacecraft was launched at 15:35:15 UTC on 4 November 1962, atop a Molniya 8K78 carrier rocket flying from Site 1/5 at the Baikonur Cosmodrome.[1] About 260 seconds into the flight, the oxidiser pressurisation system malfunctioned, resulting in cavitation within the feed lines and turbopump. The same problem developed in the propellant feed lines thirty-two seconds later.[6] Although the lower stages of the rocket were still able to place the upper stage and payload into a low Earth orbit, vibrations caused by either the cavitation problem, or a separate problem with the next stage, caused a fuse to become dislodged in the electrical system controlling the upper stage engine. This prevented the Blok L upper stage igniting, leaving the spacecraft in its parking orbit. It decayed from orbit the next day. However, some debris remained in orbit until 27 December, and the upper stage ullage motor platform remained in orbit until 19 January 1963."
