Women in space
Women of many nationalities have worked in space. The first woman in space, Soviet cosmonaut Valentina Tereshkova, flew in 1963. Space flight programs were slow to employ women, and only began to include them from the 1980s. Most women in space have been United States citizens, with missions on the Space Shuttle and on the International Space Station. Three countries maintain active space programs that include women: China, Russia, and the United States of America. In addition, a number of other countries — Canada, France, India, Iran, Italy, Japan, South Korea, and the United Kingdom — have sent women into orbit or space on Russian or US missions.
Valentina Ponomaryova
In December 1961, the selection of female cosmonauts was authorized by the Soviet Government, with the specific intention of ensuring the first woman in space was a Soviet citizen. In February 1962 Ponomaryova was selected in a group of five female cosmonauts to be trained for a Vostok flight. The group spent several months in intensive training, concluding with examinations in November 1962, after which the four remaining candidates were commissioned Junior Lieutenants in the Soviet Air Force. Ponomaryova established herself as one of the leading candidates with Valentina Tereshkova and Irina Solovyova, and a joint mission profile was developed that would see two women launched into space, on solo Vostok flights on consecutive days. The honour of being the first woman in space was to be given to Valentina Tereshkova who would launch first on Vostok 5 while Ponomaryova would follow her into orbit on Vostok 6. However, Ponomaryova did not respond with standard Soviet cliches in interviews and her feminism made the Soviet leadership uneasy, and this led to the flight profile being altered in March 1963. Vostok 5 would now carry a male, cosmonaut Valery Bykovsky, flying the joint mission with Tereshkova aboard Vostok 6 in June 1963. Tereshkova's backup was Irina Solovyova, with Ponomaryova in a supporting 'second back-up' role.
