Spaceflight Missions

Kizim commanded three major missions: Soyuz T-3, Soyuz T-10, and Soyuz T-15. His final mission, Soyuz T-15, remains distinct for its logistical achievement of visiting both the Mir and Salyut 7 space stations during a single flight. This feat required precise orbital maneuvering and demonstrated the potential for modular station maintenance and expansion. He also served as a backup commander for the Soyuz T-2 mission.

Military and Academic Service

Following his departure from the active cosmonaut program on June 13, 1987, Kizim continued his service within the military infrastructure. He held the position of Deputy Director of the Satellite Control-Center for the Russian Ministry of Defense. In 1993, he took charge of the Mozhaysky Military-Space Academy, a post he maintained until his retirement from the Russian Air Force on September 10, 2001, at the rank of Colonel General. He also served as Director of the Military Engineering Academy of Aeronautics and Astronautics in St. Petersburg starting in May 1995.

Recognition and Legacy

Kizim received numerous decorations for his contributions to space exploration and military service. He was twice named a Hero of the Soviet Union in 1980 and 1984 and held the title of Pilot-Cosmonaut of the USSR. Other notable awards include three Orders of Lenin, the Order of Honour in 1998, and the Order of Merit (3rd class) from Ukraine in 2001. He was further recognized as an Honoured Master of Sports of the USSR. He died in 2010 in Moscow and is buried at the Troyekurovskoye cemetery.
