Margaret Hamilton, a pivotal figure in the history of space exploration and computer science, has died. Hamilton is best known for leading the team that developed the onboard flight software for NASA’s Apollo program, including the critical guidance systems used during the Apollo 11 moon landing. Her work is frequently cited by historians for its robustness; specifically, the software's ability to prioritize essential tasks during a computer overload prevented the lunar module from aborting its landing.

Beyond her contributions to the Apollo missions, Hamilton is credited with formalizing the discipline of 'software engineering.' At a time when software development was often viewed as secondary to hardware, she advocated for the professionalization of the field. Following her tenure at the MIT Instrumentation Laboratory, she founded two successful software companies, continuing her influence on the industry for decades. Her legacy remains a central point of discussion regarding the history of human spaceflight and the evolution of modern computing.
