Joint flight with Vostok 5. First woman in space, and the only Russian woman to go into space until Svetlana Savitskaya 19 years later. On its first orbit, Vostok 6 came within about five km of Vostok 5, the closest distance achieved during the flight, and established radio contact. Flight objectives included: Comparative analysis of the effect of various space-flight factors on the male and female organisms; medico-biological research; further elaboration and improvement of spaceship systems under conditions of joint flight. It was Korolev's idea just after Gagarin's flight to put a woman into space as yet another novelty. Khrushchev made the final crew selection. Korolev was unhappy with Tereshkova's performance in orbit and she was not permitted to take manual control of the spacecraft as had been planned. Recovered June 19, 1963 8:20 GMT. Landed 53:16 N 80:27 E.

Planned all-female ten day long-duration flight. Solovyova would have conducted the first female space walk. Cancelled in spring 1966, after death of Korolev, in order to concentrate on Soyuz and Lunar landing programs.
