The first woman flew to space in 1963. Since then, 102 more women have flown to space, representing more than 15% of total astronauts, in more than 173 launches. The number of astronauts includes reflights by the same person, but in different years. The definition of astronaut is someone who was launched or has flown with the intention of reaching an altitude greater than the Kárman line (including, thus, the ill-fated astronauts from the Challenger disaster, but not the space travelers of Virgin Galactic flights, for example).
