Katherine Johnson was a brilliant mathematician who helped send astronauts to space and to the Moon! She was so good at math that people called her a human computer. Katherine showed everyone that girls can be great at math and change the world with their smart brains!
When NASA was trying to send the first astronauts into space, they asked Katherine to solve super hard math problems. Her numbers told the spaceships exactly where to go and how to return safely to Earth! She helped plot the flight path for the very first American in space and even helped astronauts travel to the Moon. The astronauts trusted her math so much that they asked her to double-check the computers!
