In July 1969, Apollo 11 astronauts Neil Armstrong, Michael Collins, and Buzz Aldrin achieved humanity’s first Moon landing, fulfilling President Kennedy’s 1961 goal. Iconic phrases like “Houston, Tranquility Base here, the Eagle has landed” and “That’s one small step for [a] man, one giant leap for mankind” mark this historic event. Scientists examined Moon rocks shortly after the splashdown, while the astronauts underwent a three-week quarantine.
