Crew

Flight:

Female cosmonauts with Korolev

Tereshkova aboard Vostok 6

• Joint flight with Vostok 5. First woman in space, and the only Russian woman to go into space until Svetlana Savitskaya 19 years later. 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.
