| 説明 | President Barack Obama presents former NASA mathematician Katherine Johnson with the Presidential Medal of Freedom, as professional baseball player Willie Mays, right, looks on, Tuesday, November 24, 2015, during a ceremony in the East Room of the White House in Washington. Johnson's computations have influenced every major space program from Mercury through the Shuttle program. Johnson was hired as a research mathematician at the Langley Research Center with the National Advisory Committee for Aeronautics (NACA), the agency that preceded NASA, in 1953. Johnson exhibited exceptional technical leadership and is known especially for her calculations of the 1961 trajectory for Alan Shepard’s flight (first American in space), the 1962 verification of the first flight calculation made by an electronic computer for John Glenn’s orbit (first American to orbit the earth). In her later NASA career, Johnson worked on the Space Shuttle program and the Earth Resources Satellite and encouraged students to pursue careers in science and technology fields.NASA Media Usage GuidelinesCredit: NASA/Bill IngallsImage Number: NHQ201511240002Date: November 24, 2015 |
