On board the space station Salyut 1 he operated the Orion 1 Space Observatory (see Orion 1 and Orion 2 Space Observatories), he became the first man to operate a telescope outside the Earth’s atmosphere. After a normal re-entry, the capsule was opened and the crew was found dead. It was discovered that a valve had opened just prior to leaving orbit that had allowed the capsule’s atmosphere to vent away into space, suffocating the crew. One of Patsayev’s hands was found to be bruised, and he may have been trying to shut the valve manually at the time he lost consciousness.LaunchesSoyuz | Soyuz 11Russian Federal Space Agency (ROSCOSMOS)Type: Government Abbreviation: RFSA Administration: Administrator: Dmitry Rogozin Founded: 1992 Launchers: Soyuz Spacecraft: Soyuz Country: RUSThe Roscosmos State Corporation for Space Activities, commonly known as Roscosmos, is the governmental body responsible for the space science program of the Russian Federation and general aerospace research.
