Quick Summary

Margaret Hamilton, who created the software that powered NASA’s Apollo 11 moon landing and pioneered computer programming in an era before it became common, passed away at age 90 on September 30. At MIT, she learned to program under a meteorologist and later developed error detection and recovery mechanisms for the Apollo mission's onboard flight system, which successfully handled critical hardware issues during the historic lunar landing in 1969. President Obama highlighted her contributions when he awarded her the Presidential Medal of Freedom in 2016.

Story summary

Margaret Hamilton, 90, the computer pioneer whose software powered the Apollo 11 moon landing, died in September 2022. At MIT, she learned programming from a meteorologist and later joined Nasa's Apollo project as its first programmer and female hire. Her software played a critical role during the historic mission when alarms sounded minutes before landing. Despite potential hardware issues, Hamilton’s software ensured mission continuation by detecting problems and compensating for them, restarting essential tasks to ensure a successful moon landing.
