Mir Main Expedition EO-01. Epic repair mission. Crew comprising ship's commander L D Kizim and flight engineer V A Solovyov first docked with the Mir orbital station to conduct scientific and technical studies and experiments. Mir then maneuvered 17 April to match Salyut 7 at 4000 km separation, then again on 4 May to catch up. After six weeks aboard Mir, Soyuz T-15 undocked on 5 May, then rendezvoused with the dead Salyut 7 station. Only docking to date by a single spacecraft with two space stations. After manual docking with inoperative Salyut 7, the station was found to be ice bound and without electrical power. Crew repaired the station, regaining power, heat, and environmental control. Removed experimental results left behind by last crew. Undocked Salyut 7 on 25 June, and redocked with Mir on 26 June. Landed 55 km NE Arkalyk. Recovered July 16, 1986 12:34 GMT. No crew ever revisited Salyut 7; it made an uncontrolled reentry over Argentina.
Tested truss structure.
