Sigmund Jähn, born in Morgenröthe-Rautenkranz, was the first German astronaut, completing a space mission as part of the Interkosmos program in 1978.
To commemorate the joint USSR – GDR space flight, a permanent exhibition was opened in his hometown in 1979 under the name Permanent exhibition of the first joint cosmos flight USSR – GDR (German: Ständige Ausstellung des ersten gemeinsamen Kosmosfluges UdSSR–DDR).
Today, Jähn's hometown is part of the municipality of Muldenhammer in the rural district of Vogtlandkreis.
Today it serves as a guesthouse and bistro, with decor inspired by space travel and steampunk.
