Soyuz T-10

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.[1]

This article is about the successful mission. For the failed mission originally designated Soyuz T-10, see Soyuz 7K-ST No.16L.

Mission highlights

Fifth expedition to Salyut 7. 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.[3] 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.
