Soyuz TM-13: the last Soviet space mission

The Soviet Union launches its last space mission, Soyuz TM-13, carrying cosmonauts Alexander Volkov, Toktar Aubakirov and the first Austrian in space, Franz Viehböck, to space station Mir. After a week in space, Aubakirov and Viehböck return to Earth aboard Soyuz TM-12 with incumbent station crewmember Anatoly Artsebarksky, while Volkov stays for 175 days (alongside Krikalev, who will have been in space for 10 months by the time he returns to Earth in 1992). During Volkov and Krikalev’s stay aboard Mir, the Soviet Union collapses; they instead return to Earth as Russian citizens.
