Soyuz TM-18 was launched from Baikonur Cosmodrome and landed 112 km north of Arkalyk. TM-18 was a two-day solo flight that docked with the Mir space station on January 10, 1994. The three cosmonauts became the 15th resident crew on board Mir. The crew did research work in space flight medicine, primarily by cosmonaut Valeri Polyakov during his long-term flight, and accomplished 25 different experiments.
