Soyuz TM-4 / Mir Expedition 3

The Soyuz TM-4 mission is launched by the Soviet Union, en route to space station Mir. Cosmonauts Vladimir Titov and Musa Manarov take up residence as the new long-duration crew aboard Mir, formally known as Expedition 3, and they eventually break all previous space endurance records by staying aboard Mir for exactly one year and one day, returning to Earth on December 21st, 1988. Cosmonaut Anatoli Levchenko, after the week-long overlap with the Expedition 2 crew, returns to Earth with Expedition 2 crew members Yuri Romanenko and Aleksandr Aleksandrov aboard the Soyuz TM-3 vehicle.
