Soyuz TM-20

Soyuz TM-20Russia launches the Soyuz TM-20 mission to space station Mir, carrying cosmonauts Alexander Viktorenko and Yelena Kondakova, and German astronaut Ulf Merbold, who will remain for only a month to conduct experiments in orbit. A glitch in the automated docking system forces Viktorenko to assume manual control for the docking with Mir, a problem which will plague future Mir crews. Viktorenko and Kondakova remain aboard Mir for 169 days, returning to Earth in March 1995 with the new space endurance world record holder, Dr. Valery Polyakov, who has spent 420 days in orbit.
