Soyuz 36
Soyuz 36 is launched by the Soviet Union on a one-week mission to space station Salyut 6. The crew consists of Apollo-Soyuz veteran Valery Kubasov and the first Hungarian in space, Bertalan Farkas. During the crew’s week-long visit to Salyut 6, they undertake an exhaustingly jam-packed series of experiments before swapping Soyuz vehicles with the long-duration station crew – technically, the Soyuz 36 crew returns in the Soyuz 35 vehicle on June 6th.
