Valentina Tereshkova, in full Valentina Vladimirovna Tereshkova, (born March 6, 1937, Maslennikovo, Russia, U.S.S.R.), Soviet cosmonaut, the first woman to travel into space. On June 16, 1963, she was launched in the spacecraft Vostok 6, which completed 48 orbits in 71 hours. In space at the same time was Valery F. Bykovsky, who had been launched two days earlier in Vostok 5; both landed on June 19.
An astronaut (or cosmonaut) is a person trained by a human spaceflight program to command, pilot, or serve as a crew member of a spacecraft.
Although generally reserved for professional space travelers, the terms are sometimes applied to anyone who travels into space, including scientists, politicians, journalists, and tourists.
