What Did Katherine Johnson Do at NASA?
Trajectory Calculations for Early Space Missions
Johnson performed trajectory analysis for Alan Shepard’s Freedom 7 mission in 1961 and verified the orbital calculations for John Glenn’s Friendship 7 flight in 1962. According to NASA, Glenn personally requested that Johnson recheck the electronic computer’s numbers before his mission.
Johnson considered her greatest work to be the calculations that synchronized Apollo’s Lunar Module with the Command and Service Module in lunar orbit – a critical step for the Apollo 11 moon landing.
Work on the Space Shuttle and Earth Satellites
Later in her career, Johnson worked on the Space Shuttle program and on the ERTS (Earth Resources Technology Satellite, later Landsat) project. She authored or co-authored 26 research reports, according to NASA’s official biography.
Role in the Mercury Program and Apollo Missions
Johnson’s trajectory and orbital calculations were essential for both Earth orbit missions and lunar mission planning. NASA’s biography highlights her role in the Apollo group award and lunar spacecraft operations.
Who Was Katherine Johnson’s Husband?
James Goble – First Marriage
Katherine Johnson married James Goble in November 1939. According to the Katherine Johnson Foundation, she left graduate school to start a family with Goble. They had three daughters: Constance, Joylette, and Katherine (sometimes called Kathy). James Goble died in 1956.
James A. Johnson – Second Marriage
After Goble’s death, she married James A. Johnson in 1959. Biography.com notes that this second marriage lasted until Jim Johnson’s death in 2019. The couple lived in Newport News, Virginia.
Family Background
Johnson was the youngest of four children born to Joshua and Joylette Coleman. Her father worked as a farmer and handyman; her mother was a teacher. The family placed a high value on education, which drove Johnson to excel in school despite the limited opportunities available to Black children in segregated West Virginia.
What Awards Did Katherine Johnson Receive?
Johnson received numerous honors over her lifetime. The most prominent was the Presidential Medal of Freedom, America’s highest civilian award, presented by President Barack Obama in 2015. The White House ceremony recognized her contributions to space exploration.
NASA gave Johnson the Apollo Group Achievement Award and the Lunar Spacecraft Operations Group Award. In 1997, the National Technical Association named her Mathematician of the Year. She also received several honorary doctorates.
In 2016, NASA named its Katherine Johnson Computational Research Facility at Langley Research Center in her honor. She did not win the Nobel Prize, but her legacy is carried forward by the Katherine Johnson Foundation, which promotes STEM education.
Although Hidden Figures brought her story to a wide audience, Johnson was not the only mathematician highlighted. Dorothy Vaughan and Mary Jackson also played key roles. The film compressed some events for storytelling, as is common in historical dramas.
