Launch from the Baikonur Cosmodrome; landing 145 km north of Karaganda.

The main goals of this mission in the official version were to test spacecraft systems and designs, manoeuvring of space craft with respect to each other in orbit, and to conduct scientific, technical and medico-biological experiments in a group flight.

It was a group flight with Soyuz 6 and Soyuz 7. There was no docking, only approaching (until 500 m to Soyuz 7). Planned docking maneuver with Soyuz 7 was not accomplished (failure of rendezvous electronics).

The landing proceeds normally.
