In July 1969, Armstrong commanded the Apollo 11 mission to the moon. He became the first person to set foot on the moon. He was quoted as saying, "That's one small step for a man, one giant leap for mankind." His companions on the flight were Michael Collins and Edwin Aldrin. He left NASA in 1971 to become a professor of aerospace engineering at the University of Cincinnati.
