Soyuz T-7 was the third mission to the Salyut 7 space station and the second to visit the long-duration Soyuz T-5 resident crew of the station. The mission began on August 19, 1982, 17:11:52 UTC, launching Commander Leonid Popov, Flight Engineer Aleksandr Serebrov and Research Cosmonaut Svetlana Savitskaya, who was the second woman in space, 20 years after Valentina Tereshkova’s flight. They docked with the station the next day. During their 7-day stay on the station, crew performed various scientific and medical experiments. Soyuz T-7, per usual, swapped their vehicles with the resident Soyuz T-5 crew, which allowed for a longer stay on the station.
The crew returned in Soyuz T-5 spacecraft, landing safely back on Earth on August 27, 1982, 15:04:16 UTC.
