Soyuz T-12 Soyuz T-12 Soyuz T-12 (also known as Salyut 7 EP-4) was the seventh manned spaceflight to the Soviet space station Salyut 7. The name "Soyuz T-12" is also the name of the spacecraft used to launch and land the mission's three-person crew. The mission occurred in July 1984, during the long-duration expedition Salyut 7 EO-3. During the mission, crew member Svetlana Savitskaya became the first woman to ever perform a spacewalk, and the potential Buran Space shuttle pilot, Igor Volk, was given spaceflight experience. Unlike many Soyuz visiting missions, the Soyuz lifeboats were not swapped, and the crew returned to
Soyuz 4 module, which also acted as an airlock. Soyuz 4 and 5 separated after 4 hours and 35 minutes docked together. Soyuz 4 re-entered the atmosphere and landed southwest of Karaganda on 17 January 1969. The mission proved it was possible to perform the activities that would be needed on a Soviet lunar landing. The Soviet plan called for a lone cosmonaut to land on the moon, return to lunar orbit, then make a spacewalk back from the landing craft to the orbiting spacecraft after docking. This was because there was no internal tunnel between the two craft as found on
