Soyuz TM-6 was a crewed Soyuz spaceflight to Mir. It was launched on 29 August 1988, at 04:23:11 UTC, for the station's third long-duration expedition, Mir EO-3. The three-person crew that was launched consisted of Research Doctor Valeri Polyakov, who became part of the EO-3 crew, as well as the two crew members of the week-long mission Mir EP-3, which included the first ever Afghan cosmonaut, Abdul Ahad Mohmand.
On September 8, Soyuz TM-6 was undocked from Mir's Kvant port and redocked onto the Mir Base Block's port. It remained there until December, when it brought Titov and Manarov of the EO-3 crew back to Earth. It also landed French astronaut Jean-Loup Chrétien, ending his 25-day-long spaceflight which started with Soyuz TM-7.
