13 Minutes to the Moon: 5. The fourth astronaut

How a briefcase-sized computer, less powerful than a smartphone, pioneered space tech for the first Moon landing. Astronauts Neil Armstrong and Buzz Aldrin rely on the software to guide their spaceflight to the lunar surface. Developed by a pioneering team of programmers, including trailblazing scientist Margaret Hamilton, the Apollo Guidance Computer helps usher in the digital age.
