Soyuz programme (Manned missions)

Soyuz TM-8 was a spacecraft used to launch and land the crew of the fifth long duration crew to the Soviet Space Station Mir.^[2] It was part of the Soyuz-TM series of spacecraft, which were the fourth generation of the Soviet Soyuz. Soyuz TM-8 was the eighth manned spaceflight to Mir, and spent 166 days in orbit.

Crew

The crew consisted of two Soviet cosmonauts. They had both been in space, but only Viktorenko had previously been to Mir, which was a 7-day visit during Mir EP-1.^[3]

Position	Crew
Commander	Alexander Viktorenko Mir EO-5 Second spaceflight
Flight Engineer	Aleksandr Serebrov Mir EO-5 Third spaceflight

Launch and Docking

The Soyuz-U2 rocket was painted with advertisements. During the Soyuz spacecraft's final approach to Mir (4 metre distance), the Kurs rendezvous and docking system malfunctioned, so Viktorenko took over manual control and withdrew to 20 metres, and then docked manually. The spacecraft spent 166 days attached to Mir, for the duration of the expedition Mir EO-5.

Return to Earth

Soyuz TM-8 landed at 04:36 UTC on 19 February 1990, after an uneventful flight to Earth.^[1]
