Deutsche Raumfahrtausstellung Morgenröthe-Rautenkranz, Space exploration museum in Muldenhammer, Germany.

The Deutsche Raumfahrtausstellung in Morgenröthe-Rautenkranz, part of Muldenhammer in Saxony, is a municipal exhibition on spaceflight and space exploration. Since 2006/2007 it has occupied a new building with far more floor space and an outdoor area with a planet park and a space-themed playground. Its four themes cover the history of spaceflight, the benefits of space travel for Earth, German space projects and the achievements of German researchers, engineers and astronauts. A second hall has been under construction since the September 2023 groundbreaking.

The exhibition opened in 1979 as the Permanent Exhibition of the First Joint USSR–GDR Space Flight, commemorating Sigmund Jähn's 1978 Interkosmos mission; Jähn was born in Morgenröthe-Rautenkranz. After German reunification in 1990 it was broadened into a pan-German space exhibition. It moved into a new building in 2006/2007, and in 2020 the street was renamed Dr.-Sigmund-Jähn-Straße. A second hall has been under construction since the 2023 groundbreaking.

The exhibition grew out of a 1979 permanent display marking the first joint USSR–GDR space flight, and since 1990 it has presented an all-German view of spaceflight. Its non-profit association counts over 250 national and international members, and nearly all German astronauts and cosmonauts belong to it. It organises symposia and spaceflight days where cosmonauts, astronauts, technicians and scientists meet enthusiasts.

The museum is open Tuesday through Sunday from 10:00 to 17:00 and welcomes visitors to this location near Zwickau. Staying overnight in surrounding small towns or larger cities in the region makes sense if you plan to spend a full day exploring the exhibition.

The walkable base block of the Soviet MIR space station is an original flown module, not a training mock-up. The exhibition also holds the original engine of a V2 rocket and the engineering model of AZUR, Germany's first satellite. The street outside was renamed Dr.-Sigmund-Jähn-Straße in 2020.
