[. ] Jähn (via his father's stories and memorabilia) and his father were impressed by the early rocketry pioneers of the 1920s around
Fritz von Opel and the first manned rockets on land and in the air, igniting his enthusiasm for aviation, rocketry and spaceflight.

On 26 April 1955, Jähn enlisted into the predecessor of the
East German Army in the town of
Preschen and eventually worked his way into the
East German Air Force. He finished basic training in 1956, enrolling into the
Officer's School in Kamenz, and was sent to flight school in the town of

Space career
Training
Jähn and
Köllner began training together in 1976, with Köllner serving as his backup pilot. The two candidates spent the next two years conducting mission-specific training and their physical health was closely monitored by physicians at the NVA's
Institute for Aviation Medicine in preparation for their upcoming flight.
Soyuz 31 mission
On 26 August 1978, Jähn and his co-pilot,
Valery Bykovsky flew aboard the
Soyuz 31 to the Soviet space station
Salyut 6. The two men were greeted by resident cosmonauts
Vladimir Kovalyonok and
Aleksandr Ivanchenkov who arrived during the
Soyuz 29 mission. Jähn's flight lasted 7 days, 20 hours, 49 minutes, and 4 seconds - orbiting Earth 124 times. During the mission, he conducted numerous scientific experiments. These included technical experiments with the

Among the advanced scientific equipment on board, the two cosmonauts carried mementos from home. Jähn brought a figurine of ''
Das Sandmännchen'', a well-known East German television character at the time, and Bykovsky brought a Misha doll, a character from a Soviet-era children's book series. They even broadcast a wedding between the two characters, which became controversial among East German and Soviet media outlets.
The Soyuz 31 remained docked to the Salyut 6 station until the custom-made seats were transferred between both Soyuz craft, where it was then used as a return vessel for Kovalyonok and Ivanchenkov. Jähn and Bykovsky later returned in the Soyuz 29 craft.

was prepared like a
general staffing brief: on the morning of 26 August 1978, the editors in chief of the GDR radio stations and newspapers all received three sealed and numbered letters. Each one contained a different announcement depending on the outcome of the flight, whether it was successful, resulted in a fatal accident, or an emergency landing in enemy territory. The corresponding letter was only to be opened and published following a telephone call with specific instructions. After the mission was a success, the letters with the negative outcomes were then collected from the organizations.
Jähn's space flight was celebrated and covered extensively by GDR media outlets, since one of the smaller German states was home to the first German in space. On Sunday, 27 August 1978, ''

An exhibition dedicated to space flight and aeronautics was constructed in the former train station of his home town Morgenröthe-Rautenkranz. This exhibit received multiple additions between 1991 and 1992, and the name was formally changed to ''The German Space Exhibition''. Since 2007, the expanded sections have been housed in a newer building not far from the original location. Furthermore, a 4.5m (~14.8 ft.) memorial was erected in the same town to commemorate the first German cosmonaut in space.
In the 2003 German film ''
Good Bye, Lenin!'', Jähn is the boyhood hero of the film's protagonist, Alex Kerner. As part of an effort to prevent his mother from learning that the Berlin Wall came down while she was in a coma and that East Germany no longer exists as a separate nation, Kerner locates a taxi driver (played by Swiss actor
Stefan Walz), who resembles the cosmonaut, to appear in a fake newscast as the successor of Communist Party Secretary

He and his wife lived there until his passing on 21 September 2019, and was buried in the
St. Mary's Protestant Cemetery in Strausberg.
When Sigmund returned from his space flight, he was greeted by his family with a picture of his grandson. This was ultimately concealed by GDR news stations because his role as a grandfather wouldn't have conformed to the desired image the space agency wanted to promote.
