Launch from Baikonur; landing 40 km northwest of Karaganda.

Planned launch on January 13, 1969 was scrubbed due of bad weather. That was the first time in Soviet space history. Docking with Soyuz 5 (Soyuz 4 had the active part). The two spacecrafts were electrical and mechanically connected , but there was no direct way from one spaceship to the other. It was the first docking of manned spacecrafts. Soyuz 5-cosmonauts Khrunov and Yeliseyev entered the Soyuz 4, in a spacewalk. After pressurisation of the Soyuz 4-capsule they were greeted by Shatalov. All three cosmonauts landed with the Soyuz 4-spacecraft. Scientific (medical and biological) and technical experiments were also performed, but all in all it were tests of lunar landing techniques.

The landing was 40 km far from the planned point.
