HAMPTON, Va. (AP) — NASA says Katherine Johnson, a mathematician who worked on NASA’s early space missions and was portrayed in the film “Hidden Figures,” about pioneering black female aerospace workers, has died. In a Monday morning tweet, the space agency said it celebrates her 101 years of life and her legacy of excellence and breaking down racial and social barriers. Johnson was one of the so-called “computers” who calculated rocket trajectories and earth orbits by hand during NASA’s early years.
