Soyuz TM-4

Soyuz TM-4 was a crewed Soyuz spaceflight to Mir. It was launched on 21 December 1987, and carried the first two crew members of the third long duration expedition, Mir EO-3. These crew members, Vladimir Titov and Musa Manarov, would stay in space for just under 366 days, setting a new spaceflight record. The third astronaut launched by Soyuz TM-4 was Anatoli Levchenko, who returned to Earth about a week later with the remaining crew of Mir EO-2. Levchenko was a prospective pilot for the Soviet Space shuttle Buran. The purpose of his mission, named Mir LII-1, was to familiarize him with spaceflight.
