Moon Landing

Apollo 11 achieved what had seemed impossible just a decade before — landing humans on the Moon and returning them safely to Earth. Neil Armstrong and Buzz Aldrin walked on the lunar surface while Michael Collins orbited above in the command module. Armstrong's words — "That's one small step for man, one giant leap for mankind" — were heard by an estimated 600 million people, about one-fifth of humanity at the time. The Moon landing was the culmination of a decade-long race between the United States and Soviet Union during the Cold War. It required the largest and most sophisticated technological effort in human history, employing 400,000 people and costing $25.4 billion (over $150 billion in today's dollars). The achievement fundamentally changed humanity's relationship with space and demonstrated what coordinated human effort can accomplish.
