Google honored Margaret Hamilton, the woman who led the development team responsible for the onboard flight software for NASA's Apollo missions, with a massive portrait composed of more than 107,000 mirrors.

Hamilton, 82, was awarded the Presidential Medal of Freedom by Barack Obama in 2016.

Apollo 11 took flight on July 16, 1969, launching the astronauts Neil Armstrong, Buzz Aldrin, and Michael Collins into space. Aldrin and Armstrong took the first steps on the moon, and the astronauts returned to Earth on July 24.

Collins later said it took the work of about 400,000 people to send mankind to the moon.

Google's portrait of Hamilton used more than 100,000 mirrors to reflect the light of moon; the tech giant said the image was larger than Central Park and could be seen more than a mile above sea level.
