On 26 August 1978, the Soyuz 31 spacecraft carried Sigmund Jähn into orbit, marking the first time a citizen of the German Democratic Republic reached space. His mission lasted 7 days, 20 hours, 49 minutes, and 4 seconds, during which he completed 124 orbits around Earth as part of the Soviet Union's Interkosmos program.
Early Career and Education
Born in 1937 in Morgenröthe-Rautenkranz, Jähn initially trained as a book printer from 1951 to 1954. He entered the Kasernierte Volkspolizei in 1955 and pursued a military career within the National People's Army. His formal education included studies at the Franz Mehring Military Academy, the Otto Lilienthal Military Academy, and the Gagarin Air Force Academy. He rose through the ranks as an airman, fighter pilot, and military scientist, eventually attaining the rank of major general.

Jähn served as a cosmonaut alongside Valery Bykovsky during the Soyuz 31 flight to the Salyut 6 space station. While in orbit, he conducted experiments involving the MKF-6 multispectral camera, material science studies on monocrystal growth, and medical research concerning the effects of weightlessness on speech and human biology. The mission concluded with a return flight in the Soyuz 29 capsule, though the landing process resulted in spinal cord injuries for Jähn when the craft hit the ground with significant force.
Post-Mission Recognition
Following his spaceflight, Jähn received several honors, including the Order of Karl Marx, the Order of Lenin, and the title Hero of the Soviet Union. His contributions to space exploration were also acknowledged through the Meritorious Military Pilot of the German Democratic Republic award. Throughout his later years, he served with the German Aerospace Center and the European Space Agency, while remaining a member of the Leibniz Society of Sciences until his death in 2019.
