Launch from the Baikonur Cosmodrome; landing 75 km west of Karaganda.

It was the first night launch in the aera of human spaceflights. The crew performed photographical and visual Earth observation, several astrophysical, physiological experiments and technical studies. One solar panel was not working well after a few days, but that was not a big problem. The capsule was set into a slow sun oriented rotation. Valentina Tereshkova and her daughter communicated via radio and television with husband and father Nikolayev. On Flight day 10 the crew was off duty. On this day they played chess via radio with cosmonaut Gorbatko on Earth. Since flight day 12, the crew became more and more problems to do concentrate work, they became tired and made some small mistakes.

The landing was without any problems, but both cosmonauts had big problems, to stand and to walk after landing. They had to be dragged along by the arms and they looked very ill. There was no knowledge about the effects of zero-G for humans and so there were no plans and equipment (for example chairs) for the ill crew, which was brought then to hospital. But all in all a new spaceflight duration record was performed. But it was the final record perfomed by a solo flying spaceship. Following records were set by spaceships, which travelled to orbital stations.
