The art of space mission patches is now more than six decades old, dating to the Vostok 6 mission in 1963 that carried Soviet cosmonaut Valentina Tereshkova into low-Earth orbit for nearly three days. The patch for the first female human spaceflight showcased a dove flying above the letters designating the Soviet Union, CCCP. That patch was not publicly revealed at the time, and the use of specially designed patches was employed only infrequently by subsequent Soviet missions.
