Launch from the Baikonur Cosmodrome; landing 620 km northeast of Karaganda; first female cosmonaut.

Flight objectives included: Comparative analysis of the effect of various spaceflight factors on the male and female organisms; medico biological research; further elaboration and improvement of spaceship systems under conditions of joint flight.

Rendezvous flight with Vostok 5 (4,5 km distance) at time; directly communication between both capsules during closest approach.

During the mission Tereshkova suffered from space sickness and did not reply during several communications sessions. It is unknown until today, if this was due to an equipment failure or, that she had been paralysed with fear. It was also planned, that she took manual control of the spacecraft, but that was cancelled. Tereshkova hat also problems (pain) with her right shin. She did not eat enough during their flight, because the bread was too dry.

On the other side, she filmed cities, forests, and rivers, but didn't complete the biological experiment - she couldn't reach the equipment. Star observations were also performed and she took two photometric measurements, even writing was no problem.

Many errors occurred in the entire landing sequences, including actions of the VVS recovery forces. Both spacecraft landed two degrees of latitude north of the aim point. It was calculated that this could have occurred by duplicate landing commands having been sent, but such a failure could not be duplicated in post flight tests of ground equipment.
