The movie focusses on three women Katherine Johnson, Dorothy Vaughan, and Mary Jackson, who were part of a larger group who did the calculation by hand that would allow for the safe space travel and re-entry to earth that was required before the advent of non-human computers. It is racism that has hidden this story until now as it continues for so many important figures in our collective history.
We need to keep telling these stories to each other for the sake of our children and their future in our world.
