It was on August 26th, 1920 that the 19th Amendment to the United States Constitution was certified, giving American women full voting rights. August 26th is now Women’s Equality Day. Designated in 1973, the date celebrates the Women’s Suffrage Movement and underscores the continuing work for equality for women and girls.

NASA has marked this persistent effort with a video introduction to eleven space pioneers, including physicist Pearl Young, engineer Kitty O’Brien Joyner, mathematician Dorothy Vaughan, mathematician Katherine Johnson, Chief of Astronomy and “Mother of Hubble” Nancy Grace Roman, and launch director Charlie Blackwell-Thompson.
