Mission overview

The focus of the work was on astronomical and astrophysical investigations. The mirror of the main solar observation instrument had to be recoated.

The orbit height of Salyut 4 was about 350 km above the earth (favorable in terms of astronomical observations), therefore maneuvers to approach the station were necessary.

With a flight duration of 29 days, a new Soviet long-term record was set. In contrast, the Americans had spent almost three months in a space station with Skylab 4 .
