In which space craft did Valentina Tereshkova make her historic space flight?

Valentina Vladimirovna Tereshkova (born 6 March 1937) is a member of the Russian State Duma, engineer, and former cosmonaut. She is the first and youngest woman to have flown in space with a solo mission on the Vostok 6 on 16 June 1963. She orbited the Earth 48 times, spent almost three days in space, and remains the only woman to have been on a solo space mission.

The Vostok 6 was launched on June 16, 1963. While Vostok 5 had been delayed by technical problems, Vostok 6's launch proceeded with no difficulties. Data collected during the mission provided better understanding of the female body's reaction to spaceflight. Like other cosmonauts on Vostok missions, Tereshkova maintained a flight log, took photographs, and manually oriented the spacecraft. Her photographs of the horizon from space were later used to identify aerosol layers within the atmosphere.

The mission, a joint flight with Vostok 5, was originally conceived as being a joint mission with two Vostoks each carrying a female cosmonaut, but this changed as the Vostok program experienced cutbacks as a precursor to the retooling of the program into the Voskhod program. Vostok 6 was the last flight of a Vostok 3KA spacecraft.
