Soyuz TM-7 was a crewed Soyuz spaceflight to Mir. It launched on 26 November 1988, at 15:49:34, and was the start of the fourth long duration expedition to Mir, Mir EO-4. The crew would join the third crew member of EO-4, cosmonaut/physician Valeri Polyakov, who was on Mir for the second half of EO-3. Also launched by Soyuz TM-7 was French astronaut Jean-Loup Chrétien, who would take part in the 24-day French mission known as Mir Aragatz. The spacecraft Soyuz TM-7 remained docked to Mir for the duration of EO-4. At the end of EO-4 in April 1989, due to delays in the launch schedule, Mir was left uncrewed, and all three EO-4 crew members were transported back to Earth.
