Pioneering Columbia crew
In June 1991, three women flew together to space for the first time, which they did during the STS-40 Space Shuttle Columbia mission. NASA astronauts M. Rhea Seddon, Tamara Jernigan, and Millie Hughes-Fulford served on the fifth dedicated Spacelab mission (a reusable lab used on some Shuttle missions), and the first to be dedicated solely to life science.
