Short answers, pulled from the story.
Armstrong said, "That's one small step for a man, one giant leap for mankind." He stepped onto the lunar surface at 02:56 UTC on the 21st of July 1969. The transmission was heard live by an estimated 530 million people worldwide, roughly 20 percent of the global population at the time.
Neil Alden Armstrong was born on the 5th of August 1930, in rural Washington Township, Auglaize County, Ohio. He was the son of Viola Louise Engel and Stephen Koenig Armstrong, and grew up moving across Ohio before the family settled in Wapakoneta.
Armstrong resigned from NASA in 1971 and taught aerospace engineering at the University of Cincinnati until 1980. He also served on the Rogers Commission investigating the Space Shuttle Challenger disaster in 1986 and acted as a spokesman for several American companies, including Chrysler from January 1979.
Gemini 8 launched on the 16th of March 1966 and achieved the first docking of two spacecraft in history. A stuck thruster caused the docked vehicles to spin dangerously, and Armstrong engaged the Reentry Control System to stabilize them, which by mission rules forced an early return to Earth.
On the 6th of May 1968, Armstrong ejected from a Lunar Landing Research Vehicle 100 feet above the ground moments before it crashed and burst into flames. Later analysis found that had he ejected half a second later, his parachute would not have had enough altitude to open. His only injury was from biting his tongue.
Armstrong died on the 25th of August 2012, at age 82, from complications following coronary bypass surgery performed on the 7th of August 2012 at Mercy Health Fairfield Hospital in Fairfield, Ohio. His cremated remains were scattered in the Atlantic Ocean on the 14th of September 2012.
