Mathematician & trailblazer Katherine Johnson turns 100On the image above, Katherine Johnson is calculating spacecraft trajectories… by hand! Astronaut John Glenn trusted her more than computers, and her accuracy in orbital mechanics equations helped NASA to fly the first men to the moon. On top of that, she was a race and gender pioneer.Johnson turned 100 yesterday (26 Aug), which also coincided with Women’s Equality Day. How incredible?! Johnson at the opening of Katherine G. Johnson Computational Research Facility at NASA’s Langley Research Center in 2017. Image credit: David C. Bowman/NASA The story of Johnson, Dorothy Vaughan and Mary Jackson, three brilliant black female scientists whose calculations were critical to the success of early manned NASA missions, is told in the movie and book Hidden Figures. -- source link
