Neil Armstrong was the first man to walk on the Moon. He accomplished this historic feat on July 20, 1969, during NASA's Apollo 11 mission. As he stepped onto the lunar surface, he famously declared, "That's one small step for [a] man, one giant leap for mankind." Armstrong was joined by Buzz Aldrin, who followed him shortly after. Their mission marked a significant milestone in space exploration and human achievement, demonstrating the capabilities of technology and human spirit in reaching beyond Earth. The Apollo 11 mission remains a cornerstone of space history and human exploration of the cosmos.
