Soyuz T-10 was the fifth expedition to the Salyut 7 space station. It entered a darkened and empty station because of the loss of Soyuz T-10a. It was visited by the sixth and seventh expeditions. During the course of the cosmonauts stay, three extravehicular activities took place to repair a fuel line. During their multiple spacewalks to perform maintenance on the station, the crew set a record for spacewalk hours.

Visited by 6th and 7th expeditions. The three-person Mayak crew entered the darkened Salyut 7 station carrying flashlights. The cosmonauts commented on the burnt-metal odor of the drogue docking unit. By 17 February 1984, Salyut 7 was fully reactivated, and the cosmonauts had settled into a routine. Physician Oleg Atkov did household chores and monitored his own health and that of his colleagues, who conducted experiments. During the previous year a fuel line on the station had ruptured. Kizim and Solovyov carried out three EVAs to try to fix the problem during the mission.
