Katherine Johnson, a mathematician whose little-known flight path calculations for NASA’s early space missions were brought to light in the 2016 film “Hidden Figures,” died on Monday at 101.
“She was an American hero and her pioneering legacy will never be forgotten.”
Johnson was one of the so-called “computers” who calculated rocket trajectories and earth orbits by hand during NASA’s early years.
In 1961, Johnson worked on the first mission to carry an American into space. In 1962, she verified computer calculations that plotted John Glenn’s earth orbits.
At age 97, Johnson received the Presidential Medal of Freedom, the nation’s highest civilian honor.
Johnson focused on airplanes and other research at first. But her work at NASA’s Langley Research Center eventually shifted to Project Mercury, the nation’s first human space program.
“Our office computed all the (rocket) trajectories,” Johnson told The Virginian-Pilot newspaper in 2012. “You tell me when and where you want it to come down, and I will tell you where and when and how to launch it.”
In 1961, Johnson did trajectory analysis for Alan Shepard’s Freedom 7 Mission, the first to carry an American into space.
The next year, she manually verified the calculations of a nascent NASA computer, an IBM 7090, which plotted John Glenn’s orbits around the planet.
