The moon landing refers to the event when humans first set foot on the surface of the Moon. This historic achievement occurred on July 20, 1969, during NASA's Apollo 11 mission. Astronauts Neil Armstrong and Buzz Aldrin became the first and second humans to walk on the Moon, while Michael Collins remained in orbit aboard the command module. The mission aimed to explore the Moon and demonstrate the United States' capabilities in space exploration during the Space Race against the Soviet Union. The successful landing marked a significant milestone in human history and expanded our understanding of space.
