Soyuz T-10 was the third long-duration expedition to the Salyut 7 space station. The mission began on 8 February 1984, 12:07:26 UTC, launching Commander Leonid Kizim, Flight Engineer Vladimir Solovyov and Research Cosmonaut Oleg Atkov into orbit. They docked with the station the next day. During their 237-day stay on the station, crew performed various scientific and medical experiments, performed six EVAs for station maintenance, and were visited by Soyuz T-11 and Soyuz T-12 missions. Soyuz T-10, per usual, swapped vehicles with the Soyuz T-11 crew, which allowed for a longer stay on the station. The mission concluded with a safe landing back on Earth on October 2, 1984, 10:57:00 UTC.
