Soyuz T-15 / Mir Expedition 1

MirThe Soviet Union launches Soyuz T-15 on an unprecedented mission into orbit. Cosmonauts Leonid Kizim and Vladimir Solovyov become the first occupants of the newly-launched Mir space station on March 15th, where they remain until early May, at which time they undock the Soyuz T-15 vehicle from Mir and visit the powered-down Salyut 7 space station, becoming its final occupants until they return to Mir in late June, bringing several pieces of equipment and experiments cannibalized from Salyut back with them. The crew spends a total of 125 days in space, at the end of which Kizim is the most-traveled man in space, having accumulated over a year of total space travel time. Soyut T-15 is the last second-generation Soyuz vehicle to fly, returning to Earth on July 16th.
