It was thanks to Margaret Hamilton that Neil Armstrong and Buzz Aldrin could take a walk on the moon. Margaret is shown standing beside listings of the software developed by the team she was in charge of, all written out by hand. Photograph taken in 1969
The Apollo Guidance Computer system was designed for the Nasa Apollo space programme. It was first used in 1966, and within three years helped Neil Armstrong and Buzz Aldrin reach the surface of the Moon. With only 74KB of memory – less than a ONE page WORD document – it was able to control a 13,000kg spaceship, orbiting at 3,500km/h around the Moon, land it safely and return it back to Earth.
