1.7.3 Salyut 1-Type Soyuz Mission Descriptions
For information on Salyut operations during these Soyuz missions, see section 2.2.3. Dates are launch to landing.
Soyuz 10 | April 22-24, 1971 | |
Vladimir Shatalov, Alexei Yeliseyev, Nikolai Rukavishnikov Crew code name—Granit Carried three crew to Salyut 1, the first space station, in April 1971. A fault in the docking unit prevented them from entering the station. |
Soyuz 11 | June 6-29, 1971 | |
Georgi Dobrovolski, Vladislav Volkov, Viktor Patseyev Crew code name—Yantar Docked successfully with Salyut 1 on June 7, 1971. On June 27 the threeperson Soyuz 11 crew reactivated Soyuz 11 and began packing experiment results for return to Earth. At 1828 UT, June 29, they undocked. They wore hooded flight suits which protected them against the descent module's chill, but not against depressurization. The Yantars fired their Soyuz main engine to deorbit. Explosive bolts for separating the orbital and service modules from the descent module then fired simultaneously, rather than sequentially as planned. The abnormally violent separation jarred loose a 1-mm pressure equalization seal in the descent module which was normally pyrotechnically released at lower altitude. The atmosphere in the descent module vented into space within 30 sec. The crew rapidly lost consciousness and died. The descent module landed automatically in Kazakhstan without additional incident at 2317 UT.[1] |
