Historical Context

After Sputnik’s 1957 launch sparked the Cold-War Space Race, President Kennedy’s 1961 pledge led NASA to develop the Saturn V and Apollo 11, which landed on July 20 1969. MIT’s Instrumentation Laboratory wrote roughly 400,000 lines of code, and Margaret Hamilton’s priority-driven software quelled the 1202 alarm. Her 2026 death was honored by NASA, MIT and the White House.
