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
Sergey Volkov (cosmonaut) of degraded performance. After ground controllers took time to work on an antenna problem, the two cosmonauts also deployed a small satellite named Radioskaf-V which was originally planned for deployment at the beginning of the spacewalk. The satellite contained an amateur radio transmitter and a student experiment. The primary task of the spacewalk the relocation of the Strela 1 boom from the Pirs module to the Poisk module, had to be called off due to time constraints. The cosmonauts removed an antenna that helped guide the Poisk module to a docking in November 2009 and was returned to the ISS
