Since Valentina Tereshkova became the first woman in space in 1963, women have gone on to set many records for spacewalks and long-duration spaceflight on the International Space Station. Another milestone will come in 2024 when NASA aims to land the first woman on the moon under the Artemis program, named for the twin sister of Apollo.

From the first female shuttle commander to the first all-female spacewalk, we celebrate the achievements of women in space with this gallery. Take a look at some of the trailblazing women in our gallery below.
