Answer:
Katherine Johnson loved math. Early in her career, she was called a “computer.” She helped NASA put an astronaut into orbit around Earth. And then she helped put a man on the Moon. Katherine studied how to use geometry for space travel. She figured out the paths for the spacecraft to orbit (go around) Earth and to land on the Moon. NASA used Katherine's math, and it worked! NASA sent astronauts into orbit around Earth. Later, her math helped send astronauts to the Moon and back. NASA could not have done these things without Katherine Johnson and her love for math!
