[edit] 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. 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.
While aboard Salyut 6 station, on July 19, Popov and Ryumin sent their greetings to the Olympians and wished them happy starts in the live communication between the station and the Central Lenin Stadium, where the opening ceremony of the 1980 Summer Olympics was held. They appeared on the stadium's scoreboard and their voices were translated via loud speakers.
