Salyut 7

DOS-6

Mission Profile

Salyut 7 (DOS-6) was the final Soviet civilian space station in the Salyut series, launched on 19 April 1982 aboard a Proton-K and operating until 1991 as an extraordinary testbed for extended-duration spaceflight. It hosted record-setting missions including Valentin Lebedev and Anatoly Berezovoy's 211-day stay in 1982 and a 237-day mission in 1984–1985, while also conducting pioneering EVAs for external construction and maintenance experiments. Most dramatically, the station was successfully resurrected from a complete power failure in 1985 when cosmonauts Dzhanibekov and Savinyykh manually boarded the tumbling, frozen station and restored it to full operation — one of the most remarkable space rescue missions in history. Salyut 7 reentered the atmosphere in February 1991.
