Moon Landing Software Pioneer Margaret Hamilton Dies at 90

Margaret Hamilton, the visionary mathematician who spearheaded the creation of the Apollo missions' critical onboard software, passed away on September 30th in Cambridge, Massachusetts, at the age of 90. Her work was instrumental in the successful moon landings, guiding astronauts Neil Armstrong and Buzz Aldrin.

Hamilton, initially a mathematician at MIT in the early 1960s, became the first female programmer on the Apollo project in 1965. She led a team of 100, developing the complex software for the two onboard computers. She is credited with coining the term "software engineering," recognizing the sophisticated discipline behind the code.

Her innovative software proved vital during the Apollo 11 mission. As the lunar module neared the moon in July 1969, its computer flashed alarms due to an overload. Hamilton's software prioritized essential functions, preventing mission failure and enabling a safe landing on the Sea of Tranquillity.

Beyond Apollo, Hamilton contributed to Skylab and early space shuttle designs. She later founded two software companies. In 2016, President Obama awarded her the Presidential Medal of Freedom for her foundational contributions to reliable software design.
