Former US astronaut Neil Armstrong, the first man on the Moon, has died at the age of 82.
Mr Armstrong's family said he died following complications resulting from cardiovascular procedures.
As commander of the Apollo 11 mission, Mr Armstrong became the first human to set foot on the Moon on 20 July 1969.
He and fellow astronaut Edwin "Buzz" Aldrin spent nearly three hours walking on the Moon, collecting samples, conducting experiments and taking photographs.
As he stepped on the Moon's dusty surface, Mr Armstrong said: "That's one small step for [a] man, one giant leap for mankind."
Asked about his experience on the Moon, he told CBS: "It's an interesting place to be. I recommend it."
The Apollo 11 Moon mission turned out to be Mr Armstrong's last space flight.
The following year he was appointed to a desk job, being named NASA's deputy associate administrator for aeronautics in the office of advanced research and technology.
He left NASA a year later to become a professor of engineering at the University of Cincinnati.
The former astronaut lived in the Cincinnati area with his wife, Carol.
