Cosmos 1001



Cosmos 1001 was a Soviet satellite launched from the Baikonur cosmodrome aboard a Soyuz 11 rocket. It was an unsuccessful Soyuz-T test mission.

Soyuz T had a long gestation, beginning as the Soyuz VI military orbital complex Soyuz in 1967. It finally emerged as a complete redesign of the Soyuz in the late seventies. The Soyuz T introduced a revised Igla rendezvous system and a new service module with unitary translation / attitude control thrusters as part of a single bipropellant system with the main pump-fed engine. Solar panels were reintroduced; the fuel load was increased; and all new digital avionics were developed. Crew safety was improved with a new launch escape system and accomodation was provided for the first time for a three-man crew in spacesuits.
