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

It launched Russian cosmonauts Aleksandr Viktorenko, Yelena Kondakova, and German cosmonaut Ulf Merbold.

The flight carried 10 kg of equipment for use by Merbold in ESA's month-long Euromir 94 experiment program.

During automatic approach to Mir's front port, the spacecraft yawed unexpectedly.

Viktorenko completed a manual docking without additional incident.
