Visual Astronomy Display: March 2020

Last week, “human computer” Katharine Johnson passed away. Johnson’s calculations of orbital mechanics were instrumental to the success of NASA’s Apollo missions. One of the first African-American women scientists to work at NASA, Johnson’s time at NASA was fictionalized in the 2016 film Hidden Figures.  This month’s playlist includes videos in her honor.
