Launch from the Baikonur Cosmodrome; landing 312 km northwest of Kustanay.

For the first time a spacecraft with three crewmembers was launched. The spacecraft was potentially dangerous modified: crewmember without spacesuits, no ejection seats and no escape tower: Even to take a look on the instruments, the cosmonauts had to crane their neck. It was indeed a very uncomfortable flight.

Although it was a short mission, the crew performed scientific physico-technical and medico-biological research. Around the flight were many (self-made) problems, for example the selection of the crew. It should be a multi-task crew, one real cosmonaut, one doctor and one engineer. Prime and backup crew were changed nearly every week. Premier Krushchev was withdrawn from his position during the flight. So there were many suggestions, if the mission originally should have lasted longer. But the only reason were cramped conditions of the crew during the flight, the withdrawn of Krushchev and supposed problems with spacesickness of Feoktistov were not the reasons.

The spacecraft landed with its crew aboard. The crew left the capsule itself and waited for the rescue troops.
