Soyuz TM-4

Soyuz TM-4 launched from Baikonur Site 1/5 on December 21, 1987 with Vladimir Titov, Musa Manarov, and Anatoli Levchenko. After docking with Mir on December 23, Levchenko completed a short research and test-pilot visit before returning on Soyuz TM-3 with the outgoing crew, while Titov and Manarov remained aboard Mir as the station's third resident expedition. The long-duration crew handled station maintenance, Progress logistics, scientific work, visiting crews, and EVAs before returning to Earth on Soyuz TM-6 on December 21, 1988. The Soyuz TM-4 spacecraft itself remained at Mir until June 1988, when it returned the Soyuz TM-5 visiting crew.
