Soyuz 35 is the mission name for the flight of a Soviet Soyuz spaceship to the Soviet space station Salyut 6, which started on April 9, 1980 . It was the ninth visit by a manned Soyuz spacecraft to this space station and the 56th flight in the Soviet Soyuz program after the Soyuz T-1 visited the Salyut Station as an unmanned spacecraft.

Starting crew

Originally, Valentin Lebedew was planned as a flight engineer. Shortly before the start, however, he injured his leg while jumping on the trampoline, so that he had to be replaced by Ryumin, who had only spent six months on board Salyut 6 the previous year. With this flight, Ryumin became the sixth cosmonaut to make three space flights.

Mission overview

With Soyuz 35, the fourth regular team ( Salyut 6 EO-4 ) started to the scientific orbital station Salyut 6, to which the unmanned Progress 8 transporter was still coupled at the time. When the crew entered Salyut 6, Ryumin noticed that the two portholes in the transition section had lost their transparency. In addition, many scratches from micrometeorites and space debris were visible.

The cosmonauts replaced components of the station control and the life support system. They installed a new time switch and warning system that synchronized the on-board clocks with those in the control center (ZUP). In addition, a new 80 kg battery was installed and Progress 8 air tanks were replaced.

After almost two months, the spaceships were to be replaced. The fifth short-term crew Salyut 6 EP-5 consisted of Valeri Kubasow and Bertalan Farkas (Hungary) and docked with Soyuz 36 at Salyut 6 on May 27, 1980 . After a week of research together, Kubasov and Farkas boarded the old Soyuz 35 spacecraft and returned to Earth with it.

The landing module is in Budapest in the Transport Museum , which is currently closed.
