Before this mission's launch, the Salyut 7 space station suffered a solar array problem that left it derelict in orbit. Soyuz T-13 performed a manual docking to the powerless station and carried out extensive repairs. The crew used Soyuz T-13 to aim Salyut 7's solar arrays at the Sun to charge the station's batteries. It took two months and a Progress resupply craft filled with replacement parts to bring the station more or less back to operational status. Dzhanibekov landed with Soyuz T-13 while Savinykh remained on Salyut with Soyuz T-14.
