Mir EO-11 was the eleventh resident expedition to the Mir space station and the first Russian crewed spaceflight after the end of the Soviet Union. Aleksandr Viktorenko and Aleksandr Kaleri launched on Soyuz TM-14 from Baikonur on March 17, 1992 with German research cosmonaut Klaus-Dietrich Flade, docked with Mir on March 19, and took over resident operations after the visiting Mir 92 work. The expedition supported materials, space-technology, astrophysics, Earth-observation, and station-maintenance work, including a July 8 EVA by Viktorenko and Kaleri to inspect Mir's attitude-control gyrodynes.
