Mission Highlights
8th expedition to Salyut 6. Returned to Earth carrying the crew launched on Soyuz 36.
Valentin Lebedev was scheduled to be Leonid Popov’s flight engineer, but he required an operation after injuring his knee while working out on a trampoline. Ryumin, of the last crew to visit Salyut 6, was called in to fill his place. Upon entering Salyut 6, Ryumin noted that the two viewports in the transfer compartment had lost their transparency. The windows also had many chips in them caused by micrometeoroids and orbital debris.59 The cosmonauts replaced components of the attitude control system and life support system, installed a new caution and warning system, synchronized the station’s clocks with those in the TsUP, added an 80-kg storage battery, and replaced air from tanks in Progress 8.
