Pioneering African-American Nasa mathematician Katherine Johnson died today at the age of 101. She calculated rocket trajectories and Earth orbits for Nasa's early space missions and was portrayed in the 2016 Oscar-nominated film Hidden Figures. "Ms. Johnson had previously calculated the trajectory for the space flight of Alan Shepard - the first American in space. . .Such was her skill and reputation that [John] Glenn had asked for her specifically and had refused to fly unless she verified the calculations. She also helped to calculate the trajectory for the 1969 Apollo 11 flight to the Moon."  Remembered at the BBCThank you for your amazing work, Ms. Johnson. R.I.P.
