Margaret Hamilton, the mathematician whose code was instrumental in the first moon landing, has died at the age of 90. She developed the onboard flight software for the Apollo guidance computer, which was crucial to the success of the 1969 mission to the Moon. Despite her vital contribution, Hamilton received limited recognition for decades. Her work ensured the mission's success even when faced with computer overload during the landing. In recent years, she was finally honored for her pioneering achievements in software engineering. Hamilton’s legacy continues to inspire generations of computer scientists and engineers, cementing her place in space history.
