Soyuz T-8 is the mission designation for the flight of a Soviet Soyuz spacecraft to the Soviet space station Salyut 7, which started on April 20, 1983 . It was to be the fourth visit to this space station, but the coupling failed. The mission was the 68th flight in the Soviet Soyuz program.

Mission overview

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

It was the first unsuccessful coupling to a space station since 1979 ( Soyuz 33 ). When the payload fairing was blasted off, the boom with the antenna for the “Igla” automatic coupling system also fell off. The crew believed that it was still on the spaceship and just not properly extended. That is why they tried to move the boom into its position by jerking the spaceship. To do this, they used the attitude control thrusters. The failed pairing attempts consumed a lot of fuel. To ensure that there was enough fuel for re-entry, the cosmonauts switched off the attitude control and put the spaceship into a spin-stabilized flight mode as in the first Soyuz missions in the early 1970s . The landing was normal.
