Valentina Tereshkova, first female cosmonaut, Hero of the Soviet Union, 1969.
Vostok 6 (Russian: Восток-6, Orient 6 or East 6) was the first human spaceflight to carry a woman, cosmonaut Valentina Tereshkova, into space.
The spacecraft was launched on June 16, 1963. While Vostok 5 had been delayed by technical problems, Vostok 6's launch proceeded perfectly with no difficulties at all. Data collected during the mission was to allow better understanding of the female body's reaction to spaceflight. Like other cosmonauts on Vostok missions, she 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.
