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 three-day journey, the lunar module, named Eagle, separated from the command module, Columbia, and descended to the lunar surface. On July 20, 1969, Neil Armstrong became the first human to set foot on the Moon, followed by Buzz Aldrin. They spent about two and a half hours exploring the surface, collecting samples, and conducting experiments. The mission successfully returned to Earth on July 24, 1969.
