What work did Neil Armstrong do to set foot on the moon?

Neil Armstrong, as the commander of Apollo 11, played a crucial role in the mission that led to the first human landing on the Moon on July 20, 1969. He was responsible for piloting the Lunar Module, "Eagle," to a safe landing in the Sea of Tranquility.
