Moonwalker Neil Armstrong's Space Legacy

His family called him "A reluctant American hero" who was just doing his job.

But Neil A. Armstrong, who died Saturday of complications from heart bypass surgery, was a hero.

He was just shy of his 39th birthday when he lumbered down the ladder from the Apollo 11 spacecraft and stepped onto the stark lunar landscape on July 20, 1969.

"That's one small step for man, one giant leap for mankind," he said as Americans around the country watched in awe at the live footage from dark space, so far away.

That step fulfilled a challenge President John F. Kennedy issued in the early 1960s —to put a man on the moon by the end of the decade.

Armstrong began his career as a Navy fighter and test pilot before being tapped for a highly selective position as a NASA astronaut in 1962.

NASA's website features a photo of Armstrong in his flight suit, with a simple "Neil Armstrong, 1930-2012."

“He remained an advocate of aviation and exploration throughout his life and never lost his boyhood wonder of these pursuits," his family said in a statement released by NASA.

And his family has one request for the American people.

"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.”
