Launch from Baikonur; landing 120 km northwest of Karaganda.

Docking on spacestation "Salyut 1", which had been launched 3 days before. No transfer of cosmonauts into the space station because of technical problems (faulty hatch of the Soyuz spacecraft). Separating after 5,5 hours and several attempts. First night landing in the history of human spaceflights. During the landing Rukavishnikov became unconscious due of toxic air in the spacecraft.
