Mission overview

The proposed coupling with the orbital complex Salyut 7/Kosmos 1443 failed because there were problems with the automatic docking system.

It was the first failed connection to a space station since 1979 ( Soyuz 33). When the payload fairing was jettisoned, and the boom fell from the antenna for the automatic coupling system " Igla ". The crew believed that this was not extended properly still on the spaceship and only. Therefore, they tried to bring by jerky movements of the spaceship the boom into position. They used the altitude engines. The failed attempts coupling consumed a lot of fuel. To ensure that enough fuel is available for re-entry, the cosmonauts off from the height control and struck the spacecraft into a rotating stabilized flight mode, as with the first Sojusmissionen in the early 1970s. The landing was normal.
