The Soyuz-TM crew transports (T - транспортный - Transportnyi - meaning transport, M - модифицированный - Modifitsirovannyi - meaning modified) were fourth generation (1986–2002) Soyuz spacecraft used for ferry flights to the Mir and ISS space stations. It added to the Soyuz-T new docking and rendezvous, radio communications, emergency and integrated parachute/landing engine systems. The new Kurs rendezvous and docking system permitted the Soyuz-TM to maneuver independently of the station, without the station making "mirror image" maneuvers to match unwanted translations introduced by earlier models' aft-mounted attitude control.

Soyuz TM-20 was the twentieth expedition to the Russian Space Station Mir.
