Launch from the Baikonur Cosmodrome; landing 155 km northwest 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 wih Soyuz 6 and Soyuz 8. There was no docking, only approaching (until 500 m to Soyuz 8). The planned docking maneuver with Soyuz 8 was not accomplished (failure of rendezvous electronics).

The landing was without any problems, even a warning light panel showed 'ASP' - automatic landing sequence.
