Mercury 13

The Mercury 13 were thirteen American women who in 1959–60 took part in a privately funded research program run by physician William Randolph Lovelace II, a private contractor to NASA, which aimed to test and screen the women for spaceflight. The first participant, pilot Geraldyn "Jerrie" Cobb helped Lovelace identify and recruit the others. The participants successfully underwent the same physiological screening tests as the astronauts selected by NASA for Project Mercury. While Lovelace called the project the Woman in Space Program, the thirteen women later became known as the "Mercury 13" – a term coined in 1995 as a comparison to the Mercury Seven astronauts.

In the 1960s some of the women were among those who lobbied the White House and Congress to include women in the astronaut program. In 1963, Clare Boothe Luce wrote an article for Life magazine publicizing the women and criticizing NASA for its failure to include women in the astronaut program.

The Mercury 13 were not allowed into the astronaut program, never trained as a group, and did not fly into space until July 20, 2021, when one of the thirteen, Wally Funk, flew aboard the sub-orbital Blue OriginNew Shepard 4Flight 16, at age 82.

The story of these women has been retold in books, exhibits, and movies, including the 2018 Netflix-produced documentary Mercury 13.
