Major General Dr Sigmund Jähn is a German pilot, who became the first German to fly in space as part of the Soviet Union's Interkosmos programme. He flew on board Soyuz 31 to the Soviet space station Salyut 6 in 1978, after which he was awarded the title Hero of the Soviet Union, and became the first German cosmonaut. After German reunification, he worked German Aerospace Center (DLR), and also for the European Space Agency (ESA) to prepare for the Euromir missions.

He was of great help to Dr Kass as the latter trained the crew and carried out technical and scientific tests at Yuri Gagarin Cosmonauts Training Center in Star City (near Moscow) in preparation for the flight of the MEDEX Physiological laboratory that flew on the MIR station in 1997.
