Apollo Software Pioneer Margaret Hamilton Dies at 90
Margaret Hamilton was a computer scientist who helped write the software for the Apollo missions.
Her team’s software helped guide astronauts toward the Moon.
During Apollo 11’s landing, two alarms appeared in the spacecraft.
The software handled the problem by restarting and focusing on the most important tasks.
Mission controllers decided the landing could continue.
Apollo 11 landed on the Moon in 1969.
Hamilton helped make software engineering a recognized idea.
She died at age 90, and her work was honored with major awards.
Margaret Hamilton, who led development of Apollo guidance software, died on September 30 at age 90.
During Apollo 11’s 1969 lunar descent, 1201 and 1202 alarms triggered; the software prioritized critical tasks and restarted itself.
Hamilton’s software team helped the mission continue to a successful landing after controllers assessed the alarms.
She led the MIT Instrumentation Laboratory division responsible for Apollo guidance, navigation and control software.
Hamilton was credited with popularizing “software engineering” and received the Presidential Medal of Freedom in 2016.

Landing concern
Software response
Apollo 11 alarms
Landing concern
The 1201 and 1202 alerts raised concern during the lunar module’s descent; a similar alert had caused controllers to abort a pre-mission simulation.
Software response
The software restarted itself and reduced its workload to high-priority tasks, helping controllers decide to proceed with the landing.

Quotes
Margaret Hamilton
Computer scientist who led the team behind the Apollo software
“It quickly became clear that the software was not only informing everyone that there was a hardware-related problem, but that the software was compensating for it. With only minutes to spare, the decision was made to go for the landing. The rest is history”
