"That's one small step for man, one giant leap for mankind"
Neil Armstrong, one of the astronauts on Apollo 11 and the first man to ever step foot on the moon, has died at the age of 82.
Armstrong underwent heart surgery some three weeks back. His family said he died following complications resulting from cardiovascular procedures.
"For those who may ask what they can do to honor Neil, we have a simple request. Honor his example of service, accomplishment and modesty, and the next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink," his family said in a statement.
Before becoming an astronaut, Armstrong was in the US Navy and served as a test pilot at the National Advisory Committee for Aeronautics (NACA) High-Speed Flight Station.
He was a participant in the U.S. Air Force's Man In Space Soonest and X-20 Dyna-Soar human spaceflight programs, and joined the NASA Astronaut Corps in 1962.
His first spaceflight was the NASA Gemini 8 mission in 1966, for which he was the command pilot, becoming one of the first US civilians to fly in space, performing the first manned docking of two spacecraft with pilot David Scott.
His second and last spaceflight was as mission commander of the Apollo 11 moon landing mission on July 20, 1969. On this mission, Armstrong and Buzz Aldrin descended to the lunar surface and spent 2½ hours exploring while Michael Collins remained in orbit in the Command Module.
