Neil Armstrong, the astronaut who became first to walk on the moon as commander of Apollo 11, has died. He was 82 years old.
Armstrong had heart surgery several weeks ago, and a statement from his family said he died following complications resulting from cardiovascular procedures.
"Neil Armstrong was also a reluctant American hero who always believed he was just doing his job," his family said. "He served his Nation proudly, as a navy fighter pilot, test pilot, and astronaut. ... He remained an advocate of aviation and exploration throughout his life and never lost his boyhood wonder of these pursuits."

On July 20, 1969, half a billion people -- a sixth of the world's population at the time -- watched a ghostly black-and-white television image as Armstrong backed down the ladder of the lunar landing ship Eagle, planted his left foot on the moon's surface, and said, "That's one small step for (a) man, one giant leap for mankind."
Twenty minutes later his crewmate, Buzz Aldrin, joined him, and the world watched as the men spent the next two hours bounding around in the moon's light gravity, taking rock samples, setting up experiments, and taking now-iconic photographs. The third member of their crew, Michael Collins, orbited overhead in the Apollo 11 command ship, Columbia.
"Neil and I trained together as technical partners but were also good friends who will always be connected through our participation in the mission of Apollo 11," said Aldrin today in a statement. "Virtually the entire world took that memorable journey with us. I know I am joined by millions of others in mourning the passing of a true American hero and the best pilot I ever knew."
Collins said, "He was the best, and I will miss him terribly."
President Obama issued a statement from the White House:
"Neil was among the greatest of American heroes -- not just of his time, but of all time," it said. Armstrong and his crewmates "set out to show the world that the American spirit can see beyond what seems unimaginable -- that with enough drive and ingenuity, anything is possible."
