Apollo software engineer Margaret Hamilton dies aged 90
Margaret Hamilton, a leading Apollo software engineer, has died aged 90.
At MIT, she directed the team that developed the computer systems astronauts used to guide and control Apollo spacecraft.
Those systems helped steer spacecraft automatically and gave astronauts a keypad for navigation and control.
During Apollo 11’s 1969 moon landing, alarms sounded as the lunar module descended, and mission control considered aborting.
Hamilton recognised the alarm from earlier simulations and had advised controllers that they could ignore it unless it kept happening.
The landing continued, and Apollo 11 reached the moon, with the Eagle touching down five minutes after the alarm.
Her work was part of a programme that took humans to the moon and helped establish software engineering as a vital part of spaceflight.
Margaret Hamilton, a software engineer who directed the Apollo software team at MIT, has died aged 90.
Her work helped develop the Apollo Guidance Computer, which controlled the command and lunar modules.
During Apollo 11’s lunar landing in 1969, Hamilton’s prior simulations helped mission controllers decide that an alarm could be ignored.
The Eagle landed safely, and Neil Armstrong and Buzz Aldrin became the first people to reach the moon.
Hamilton was born in Paoli, Indiana, and earned a BA in 1958.

Hamilton earned her BA and married fellow student James Hamilton.
Hamilton was assigned work on the US air-defence systems after working in MIT’s meteorology department.
During Apollo 11’s lunar-module descent, alarms sounded; mission controllers were reassured they could be ignored.
Apollo 11 became the first mission to put humans on the moon.
