Interkosmos cosmonaut Bertalan Farkas was the first Hungarian in space on Soyuz 36, flown from 26 May to 31 July 1980. He flew with Russian Valeri Kubasov to the Salyut 6 space station, and spent nearly 8 days in space.
The patch was designed and produced by the Russian Zvezda corporation. When the Interkosmos organisation was formed in 1976, new emblems for uniforms and pressure suits were needed to reflect the cooperative nature of the missions. When it was announced in 1977 that Bulgaria, Czechoslovakia and East Germany would be participating in Interkosmos flights, it is likely that Zvezda was asked to produce the Bulgarian, Czechoslovak and East German joint mission Sokol-K suits and mission patches.
