Soyuz 36

Soyuz 36 carried Valery Kubasov and Bertalan Farkas, the first Hungarian cosmonaut, into space. They swapped Soyuz craft with the long-duration crew and returned to Earth in Soyuz 35; a later crew used their craft to return to Earth. Soyuz 36 was launched on 26 May 1980 with Valery Kubasov and Hungarian cosmonaut Bertalan Farkas, headed to the Salyut 6 space station where Leonid Popov and Valery Ryumin, launched aboard Soyuz 35, were resident. The flight was originally scheduled for 5 June 1979, but was cancelled due to the Soyuz 33 failure. They successfully docked at the aft port the day after launching. The flight was the fifth Intercosmos flight whereby guest cosmonauts from Soviet allied nations would visit the space station, typically for about a week. The flight was only the second time a Soviet mission had a civilian commander.
