Valentina Vladimirovna Tereshkova (Russian: Валенти́на Влади́мировна Терешко́ва; born 6 March 1937) is a retired Soviet cosmonaut and the first woman to have flown in space, having been selected from more than four hundred applicants and five finalists to pilot Vostok 6 on 16 June 1963. In order to join the Cosmonaut Corps, Tereshkova was only honorarily inducted into the Soviet Air Force and thus she also became the first civilian to fly in space. During her three-day mission, she performed various tests on herself to collect data on the female body's reaction to spaceflight.
Before being recruited as a cosmonaut, Tereshkova was a textile factory assembly worker and an amateur parachutist. After the dissolution of the first group of female cosmonauts in 1969, she became a prominent member of the Communist Party of the Soviet Union, holding various political offices. She remained politically active following the collapse of the Soviet Union and is still revered as a heroine in post-Soviet Russia.
