Apollo Lunar Program Software Pioneer Margaret Hamilton Dies at 90
American scientist Margaret Hamilton, a pioneer in developing groundbreaking software for NASA's Apollo lunar program, has passed away at the age of 90.
Margaret Hamilton, the software engineer who led the team that programmed the first computers for NASA's Apollo mission to land humans on the moon, has died at 90 years old. Her death on September 30 was announced by the Massachusetts Institute of Technology (MIT), where she worked from 1959 to the mid-1970s.
MIT described Hamilton as profoundly influential in software development, stating she "forged new paths in computer science and engineering." NASA chief Jared Isaacmen also paid tribute on X, calling Hamilton "a pioneer whose work helped make Apollo and humanity's first journeys to the moon possible."

Details
Hamilton, who studied mathematics, began working at MIT in 1959. In 1965, she joined a lab tasked with developing software to "send a man to the moon," which had secured a contract from NASA for the Apollo program's onboard flight software. MIT noted that Hamilton was the project's first programmer, and also its first female programmer.
Initially, she worked on software for uncrewed Apollo missions before being promoted to lead the team developing flight software for crewed missions. By 1968, she was the assistant director in charge of Apollo's Command and Service Module team, with over 400 people working on Apollo's software. Hamilton published more than 130 papers and later founded her own software companies, Higher Order Software and Hamilton Technologies.
Why it matters
Margaret Hamilton's contributions were fundamental to the field of modern software engineering and revolutionized space exploration. The software developed under her leadership played a critical role in the successful moon landing of Apollo 11. At a time when software was a nascent field, Hamilton's pioneering work in developing one of humanity's most complex systems left an enduring legacy in computer science and engineering.
