Apollo 11

Apollo 11 made history on July 20, 1969, when Neil Armstrong and Buzz Aldrin became the first humans to walk on the Moon while Michael Collins orbited above. This mission fulfilled President Kennedy's 1961 challenge, proved that humans could survive beyond Earth, and returned 21.5 kg of lunar samples that reshaped our understanding of planetary formation. An estimated 600 million people watched the live landing, still one of the largest global audiences in history. Outperforming every prior mission, Apollo 11 set the benchmark for human spaceflight, and all subsequent ventures into deep space stand on its shoulders.
