1977.09.29 - Salyut 6

Conduct of scientific and technical research and experiments; further testing of station design, on-board system and equipment. Soyuz 25 docking unsuccessful. EVA 20 Dec 1977 to examine forward docking port (no damage). EVA 29 July 1978 to retrieve externally mounted experiments (micrometeorites, biopolymers, radiation plates, materials tests). Soyuz 33 failure to dock due to propulsion failure April 1979. Soyuz 34 launched unmanned to provide replacement vehicle June 1979. EVA August 15 to dislodge 10 m diameter KRT-10 radio telescope from aft docking collar. Repair mission Soyuz T-3 December 1980 (temperature control hydraulics). Repair mission Soyuz T-4 March 1981 (stuck solar array). Salyut ejected a module on May 31 (perhaps retained Soyuz Orbital Module). Kosmos 1267 docks 19 June 1981. Commanded to reentry using Kosmos 1267 propulsion system over Pacific July 29 1982.
