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.
