US astronaut Neil Armstrong, the first man on the Moon, has died at the age of 82. Armstrong was commander of the Apollo 11 space flight and on July 20, 1969, he made "one giant leap for mankind". That “one small step” on the moon immortalized him in the annals of space exploration. An estimated 600 million TV viewers watched the event.
Armstrong had undergone heart surgery Aug. 8, three days after his 82nd birthday. In their announcement, his family said that he had died from post-surgery complications.
