[edit] Mission highlights

Docked with Salyut 6. Crew returned in Soyuz 29; crew duration 7 days, 20 hrs., 49 min. Jähn was first German Democratic Republic cosmonaut to orbit. Carried first German spacetraveler, paired with veteran cosmonaut Bykovski (he flew solo in Vostok 5, June, 1963). After the Yastreb crew departed from Salyut 6 in Soyuz 29 on September 3, the Foton crew transferred the Soyuz 32 to the Salyut 6 front port. Moving a replacement Soyuz to the front port became standard procedure; it freed the aft port for Progress supply ships.
