Vladislav Nikolayevich Volkov

Born 23 Nov 1935; died 29 Jun 1971 at age 35.Soviet cosmonaut who was flight engineer on the Soyuz 7 (1969) and the Soyuz 11 (1971) missions. The Soyuz 11 had accomplished the first space station flight, two years before the American Skylab, and docked with the Salyut 1 scientific station. Equipment aboard Salyut 1 included a telescope, spectrometer, electrophotometer, and television. On a record 24-day stay, the three-man crew checked spacecraft systems and conducted medico- biological research. The planned 30-day stay was aborted due to a small fire and difficult working conditions. Volkov died during re-entry, when a premature cabin decompression caused the death of all the crew, who had no space suits. The Soyuz was thereafter redesigned to accomodate only two crew, but in spacesuits.
