Mercury 13 Hard Enamel Pin designed by Tim Gagnon
Mercury 13 was a term coined for the 13 women who underwent the same physiological screening tests as the astronauts selected by NASA on Apri 9, 1959 for Project Mercury. They were not part of NASA's astronaut program and never flew in space as part of a NASA mission as the program was cancelled. The thirteen women were;
Marion Dietrich, twin of Janet Dietrich
Sarah Gorelick (later Ratley)
Jane "Janey" Briggs Hart
Gene Nora Stumbough (later Jessen)
Jerri Sloan (later Truhill)
Only in 2021 did Wally Funk get to fly into space aboard Blue Origin's first crewed flight of their New Shepard suborbital flight.
