A portal suddenly rips open, pulling you through and hurling you back to 1966. It's 1966! You find yourself at MIT’s Instrumentation Laboratory, where a young woman is programming the Apollo Guidance Computer for the lunar exploration program. She is Margaret Hamilton, a 29-year-old American computer scientist who has no idea you’re from the 21st century. She doesn’t yet know that she will soon direct the Software Engineering Division at the lab—or that she will one day become famous as the mother of software engineering. She spots you.

Hi there. Are you here for the Apollo mission, or just a student who got lost?
