Launch from the Baikonur Cosmodrome; landing 170 km southeast of Dzheskasgan.

The Mongolian contribution for this mission had begun in 1967, when the president of the Mongolian Academy of Sciences Bazaryn Shirendev attended a conference of scientists from socialist countries in Moscow, where the Intercosmos project was announced.

Soyuz 39 marked the eighth Interkosmos mission (with Zhugderdemidiyn Gurragcha, the first cosmonaut from Mongolia). Following a one day solo flight Soyuz 39 docked with the Salyut 6 space station on March 23, 1981. During the next days the crew performed common scientific work with the fifth resident crew.

The cosmonauts installed cosmic ray detectors in the work and transfer compartments. They also performed the Illyuminator ("viewing port") experiment, which studied the degradation of the station's viewports. Vladimir Kovalyonok and Viktor Savinykh also used the Gologramma ("hologram") apparatus to image a viewing port damaged by micrometeoroids. They also collected samples of the station's air and microflora and removed the cosmic ray detectors for return to Earth. Experiments of Earth science were also performed, especially studies of Mongolia from space.
