In the Press Site auditorium at the Kennedy Space Center in Florida, Taraji P. Henson speaks to members of the media during a news conference with other key individuals involved in the upcoming motion picture "Hidden Figures." The movie is based on the book of the same title, by Margot Lee Shetterly. It chronicles the lives of Katherine Johnson (played by Henson), Dorothy Vaughan and Mary Jackson, three African-American women who worked for NASA as human "computers.” Their mathematical calculations were crucial to the success of Project Mercury missions including John Glenn’s orbital flight aboard Friendship 7 in 1962. The film is due in theaters in January 2017.
