Soyuz T-10

Soyuz T-10Delayed many months during the investigation into the causes of the Soyuz T-10a near-disaster in 1983, Soyuz T-10 lifts off from the Soviet Union. Cosmonauts Leonid Kizim, Vladimir Solovyov and Oleg Atkov take up residence on space station Salyut 7 for a 236-day stay – the longest duration crew of the entire Salyut space station program – during which they have to conduct repairs to the station both inside and outside in a series of spacewalks. Left unoccupied months longer than expected, the station has powered down and must be reactivated, a process taking nearly ten days. A fuel line break on the exterior of the station must be repaired as well. The crew remains aboard Salyut 7 through October.
