Katherine Johnson was a mathematician whose calculations were critical to the success of NASA’s early space missions. She is one of the most famous Black scientists in history. Johnson’s mathematical genius played a pivotal role in the Mercury and Apollo space programs. She calculated trajectories, launch windows and re-entry paths for many of NASA’s missions, including Alan Shepard’s 1961 flight and John Glenn’s historic orbit around the Earth in 1962. Her calculations were so accurate that Glenn specifically requested her verification before his flight. Johnson’s work was instrumental in ensuring the safety and success of NASA’s missions during the space race.
Katherine Johnson’s contributions to space exploration were recognized with the Presidential Medal of Freedom in 2015. Her story gained widespread attention following the publication of the book “Hidden Figures” and the subsequent film adaptation, bringing her achievements to a broader audience. She is celebrated not only for her groundbreaking work as a mathematician but also for breaking barriers as an African American woman in a male-dominated field.
