Apollo 11 was the first manned mission to land on the Moon, launched by NASA on July 16, 1969. The spacecraft carried three astronauts: Neil Armstrong, Buzz Aldrin, and Michael Collins. After a journey of about four days, the lunar module, named Eagle, separated from the command module, Columbia, to descend to the Moon's surface. On July 20, 1969, Neil Armstrong became the first human to set foot on the Moon, followed by Buzz Aldrin. They spent approximately two and a half hours exploring the lunar surface, collecting samples, and conducting experiments before returning to the command module for the trip back to Earth.
