Michael Collins was a part of the Apollo 11 crew that included Neil Armstrong and Buzz Aldrin. While, the two - Armstrong and Aldrin - created history by walking on the Moon, Collins stayed behind and piloted the command module as it circled above. Hence, despite being on the mission Micheal Collins never walked on the Moon. This is why he is often called the 'forgotten astronaut'. Collins retired from NASA in 1970.
