Soyuz T-12 (also known as Salyut 7 EP-4) was the seventh crewed 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 Earth in the same spacecraft in which they launched.
