(The task took her a day and a half, and the numbers matched.) astronaut to circle Earth, he only climbed aboard the Friendship 7 capsule after Johnson verified the automated calculations made by an IBM computer. The next year, when John Glenn became the first U.S. spacecraft to carry a human, which flew to the edge of space before splashing down in the Atlantic Ocean. In 1961, Johnson calculated the trajectory for Alan Shepard’s Freedom 7 capsule, the first U.S. In the late 1950s, as NASA pondered how to launch humans into space and bring them safely home, Johnson’s responsibilities shifted to calculating orbital trajectories.įor the next decade, the men who bravely flew beyond the atmosphere relied on the precision of Johnson’s hand-drawn calculations. Johnson’s career transformed in 1957, when the Soviet Union launched Sputnik, the first artificial satellite, and ignited a space race with the U.S. Initially, Johnson pored over data from plane crashes, and she was soon transferred to the Flight Research Division. Her job, like the other black women with whom she worked, was to perform complex aerospace calculations by hand-the nascent machine computers of the day were not yet up to the task. There, her role was classified as “subprofessional,” and she worked in a segregated facility with a sign reading “Colored Computers” outside the door. In 1953, Johnson left her teaching job and went to work as a “computer” for the National Advisory Committee for Aeronautics-NASA’s predecessor. The east end of the moon's South Massif rises in the background at right. ![]() LRVs, also called moon buggies, are electric vehicles designed to expand astronauts' range of exploration on the low-gravity surface of the moon. “You could be a nurse or a teacher,” she said in a video interview with MAKERS, describing her early career trajectory.Īpollo 17 mission Commander Eugene Cernan checks out the lunar roving vehicle (LRV) at the Taurus-Littrow landing site in December 1972. Widespread racism and segregationist policies limited her options, even though her talent was limitless. At 18, she’d graduated from college, earning a degree in mathematics from West Virginia State College.īut as a woman, and especially as a woman of color, Johnson’s schooling and professional life were fraught with barriers. “I loved to learn so much that going to school alone wasn’t enough.”īy age 10, Johnson was in high school. They followed me everywhere … that was just the way my mind worked,” she wrote in her 2019 autobiography, Reaching for the Moon. ![]() By age four, she could spell and multiply, and she counted everything she could quantify. Women could not vote, and racial discrimination was legal, systemic, and rampant.Īs a child, Johnson displayed a natural aptitude for learning. World War I raged on, Woodrow Wilson was in his second term as president of the United States, and the Cold War-fueled space race was still decades away. Johnson was born in White Sulphur Springs, West Virginia, on August 26, 1918. “I truly loved going to work every single day.” A lifelong passion for numbers “Quietly the quality of my contribution began to outweigh the arbitrary laws of racial segregation and the dictates that held back my gender,” Johnson wrote of her early days working as a computer. Telling the story of NASA’s “computers”-the women who quite literally plotted and computed aeronautical and astronautical trajectories-the book and a subsequent Oscar-nominated movie launched Johnson into the international spotlight when she was in her mid-90s. But like the other black women who worked for NASA at the time, Johnson remained mostly unknown outside of the space agency-until 2016, when Margot Lee Shetterly published the book Hidden Figures: The American Dream and the Untold Story of the Black Women Mathematicians Who Helped Win the Space Race. Her exquisite facility with analytic geometry formed the foundation for NASA’s most daring space missions of the 1960s, including the first crewed flights to the moon. Johnson refused to be limited by society’s expectations of her gender and race while expanding the boundaries of humanity’s reach,” Barack Obama said when he awarded Johnson the Presidential Medal of Freedom in 2015.įor decades, Johnson, an African-American woman, was among NASA’s largely uncelebrated pioneers. Katherine Johnson, the stereotype-shattering mathematician whose calculations helped sling NASA astronauts into space, died February 24 at age 101.
