She also manually verified calculations produced by early computers, notably for the historic Mercury-Atlas 6 mission with astronaut John Glenn. Her expertise in applied mathematics enabled complex space rendezvous like Apollo 11's between the lunar module and command module, ensuring safe and precise maneuvers.

Impact & Legacy

Katherine Johnson's impact goes far beyond her calculations. By ensuring precision and safety of space missions, she played a decisive role in America's victory in the space race*. More than a mathematician, she became a symbol of perseverance against racial and sexist barriers, inspiring future generations to embrace STEM careers.
