Katherine Johnson has died


Aww, crap. I first learned about her in the movie Hidden Figures, which you should see if you haven’t already, where we learn that a black woman was a crucial element in doing the math that got men into space and to the moon. Now she has died after a long and distinguished career, at the age of 102.

In 1962, as NASA prepared for the orbital mission of John Glenn, Katherine Johnson was called upon to do the work that she would become most known for. The complexity of the orbital flight had required the construction of a worldwide communications network, linking tracking stations around the world to IBM computers in Washington, DC, Cape Canaveral, and Bermuda. The computers had been programmed with the orbital equations that would control the trajectory of the capsule in Glenn’s Friendship 7 mission, from blast off to splashdown, but the astronauts were wary of putting their lives in the care of the electronic calculating machines, which were prone to hiccups and blackouts. As a part of the preflight checklist, Glenn asked engineers to “get the girl”—Katherine Johnson—to run the same numbers through the same equations that had been programmed into the computer, but by hand, on her desktop mechanical calculating machine. “If she says they’re good,’” Katherine Johnson remembers the astronaut saying, “then I’m ready to go.” Glenn’s flight was a success, and marked a turning point in the competition between the United States and the Soviet Union in space.

When asked to name her greatest contribution to space exploration, Katherine Johnson talks about the calculations that helped synch Project Apollo’s Lunar Lander with the moon-orbiting Command and Service Module. She also worked on the Space Shuttle and the Earth Resources Satellite, and authored or coauthored 26 research reports. She retired in 1986, after thirty-three years at Langley. “I loved going to work every single day,” she says. In 2015, at age 97, Katherine Johnson added another extraordinary achievement to her long list: President Obama awarded her the Presidential Medal of Freedom, America’s highest civilian honor.

    Minor nit — she was 101. Would have been 102 in August. Still, an impressive run from a very impressive woman.

    I really wanted to meet her and thank her for her fine, arduous work.
    Now, the world is ever so much smaller, for the loss of living history living among us.

    And this year, Trump gave the medal of freedom to fucking Rush Limbaugh.

    At least she got hers first. But, yeah. If I were president I’d revoke Limbaugh’s. Ideally posthumously.

    NYTimes had a rather good headline on her life and contributions:

    “They asked Katherine Johnson for the moon, and she gave it to them”
