Salyut 7 EO-4-2


Vasyutin

Volkov Aleksandr

17 September 1985 12:39 GMT. Landing Date: 1985-11-21 10:31:00. Flight Time: 64.91 days. Alternate Name: Soyuz T-14 (Vasyutin, Volkov Aleksandr). Flight Up: Soyuz T-14. Flight Back: Soyuz T-14. Call Sign: Cheget (Tcheget - mountain in the Caucasus). Crew: Vasyutin, Volkov Aleksandr. Backup Crew: Saley, Strekalov, Viktorenko. Program: Salyut 7. Soyuz T-14 transported a crew comprising ship's commander V V Vasyutin, flight engineer G M Grechko and cosmonaut-researcher A A Volkov to the Salyut-7 orbital station. Grechko returned aboard Soyuz T-13 after an inspection tour, leaving the three-man TKS-3 crew (Savinykh from Soyuz T-13, together with Vasyutin and Volkov) to conduct military experiments with the Cosmos-1686 module. However the mission was cut short due to an incapacitating psychological condition developed by Vasyutin.

Narrative (adapted from D S F Portree's Mir Hardware Heritage, NASA RP-1357, 1995)

Salyut 7 now having been brought to life and generating sufficient power for the military experiments, Soyuz T-14 now arrived at the station on September 17, 1985. It brought up the rest of the TKS-3 crew (Vasyutin and Volkov) together with senior cosmonaut Grechko. After Grechko had inspected the repairs and condition of the station, he and Dzhanibekov, from Soyuz T-13, returned to earth aboard Soyuz T-13 on 26 September.

This left the TKS-3 crew (Savinykh, Vasyutin, and Volkov) aboard to conduct the military experiments. Cosmos 1686 docked to the station on October 2, 1985. This was a modified TKS spacecraft with the military 'star wars' tracking experiments mounted in a stripped-down VA capsule. The crew was to conduct these experiments, and conduct spacewalks with application to future space stations. Cosmos 1686 contained 4500 kg of freight, including large items like a girder to be assembled outside Salyut 7, and the Kristallizator materials processing apparatus. However, the TKS-3 crew were unable to complete the long-delayed military mission. By late October Vasyutin was no longer helping with experiments because he was ill. On November 13 the cosmonauts began scrambling their communications with the TsUP. Return to Earth occurred on November 21.
