Katherine Johnson received the Presidential Medal of Freedom at age 97, celebrating her outstanding contributions to NASA's space missions, as featured in the book and film 'Hidden Figures'.
Step-by-step explanation:
Katherine Johnson was awarded the Presidential Medal of Freedom in 2015. Born in 1918, she would have been 97 years old at the time she received the medal. Johnson was recognized for her invaluable contributions to NASA, including her precise calculations which were critical to the success of the first manned spaceflight and several other missions. Her pioneering work as one of the first Black women at NASA and her role in calculating the trajectory for the first moon landing established her as a notable figure in both space exploration and the civil rights movement. Johnson's story reached a wider audience through the book and subsequent film Hidden Figures.
