Soyuz 39 lifts off from the Soviet Union, carrying its two-man crew on a week-long spaceflight including a visit to space station Salyut 6. The crew consists of cosmonauts Vladimir Dzhanibekov and Jugderdemidiin Gurragchaa, the first Mongolian in space. In conjunction with the resident Salyut 6/Soyuz T-4 crew, they conduct scientific and engineering experiments, some of them studying the state of Salyut 6 after several years in orbit. The Soyuz 39 crew returns to Earth on March 30th.
