Katherine Johnson


               Katherine Johnson is an American physicist and mathematician who calculated NASA’s rocket flight trajectories. She was involved in the Apollo mission, the Space Shuttle program, the Earth Resources Satellite, and plans for a mission to Mars. Her work was so accurate that when NASA switched to using computers, they would call on her to check the computers calculations for errors. That is a very great accomplishment in life. I would be so thrilled to be an American physicist with NASA. Katherine Johnson is a great lady who reached for the stars in accomplishing her dreams and goals. It all paid off in the long run. She is a lady to remember.
