Soyuz 24
Soyuz 24 (Russian: Союз 24, Union 24) was a February, 1977, Soviet mission to the Salyut 5 space station, the third and final mission to the station, the last purely military crew for the Soviets and the final mission to a military Salyut. The cosmonauts Viktor Gorbatko and Yuri Glazkov re-activated the station after toxic fumes had apparently terminated the mission of Soyuz 21, the previous crew.
