Katherine calculated the trajectory for the May 5, 1961 space flight of Alan Shepard, the first American in space. She also calculated the launch window for his 1961 Mercury mission. She plotted on board navigation charts carried by astronaut missions in case of system and comms failures. When NASA used electronic computers for the first time to calculate John Glenn’s orbit around Earth, Katherine was relied on to verify the computer’s numbers. John Glenn refused to fly unless Johnson verified the calculations ...
