Mission overview

Soyuz 40 brought the ninth Interkosmos crew (also the tenth visiting crew, Salyut 6 EP-10) to the Salyut 6 space station. There they visited the 6th regular team (Salyut 6 EO-6) Vladimir Kovaljonok and Viktor Savinych , who were with Soyuz T-4 started.

Soyuz 40 was the last spaceship to dock with Salyut 6 and at the same time the end of the first phase of the manned Interkosmos program. The Romanian Prunariu mainly observed the earth's magnetic field . The scheduled earth observations were postponed until the last opportunity to fly over Romania on the last day. At this point, the team also tested the station's orientation system.

With this flight, the use of the spacecraft type 7K-T , which was replaced by the now tried and tested Soyuz T (7K-ST) , also ended.
