2day is The 40th Anniversary Of A Man Neil Armstrong's Stepping On Moon In Mission Apollo 11 ..A Man 's Eve First Landing On Moon...

Apollo 11, the historic eight day mission to the moon, which took place from July 16-24, 1969, and made astronauts Neil Armstrong and Buzz Aldrin household names, celebrates its 40th anniversary this year.Forty years ago today, Neil Armstrong became the most famous man on the planet by taking a short walk off of it. Since then he's tried to live with that fact, and also live it down.

"Neil has a very strict sense of what's appropriate to be involved in, and has since he was a boy," says Hansen, a former NASA historian 

who spent nearly three years corresponding with Armstrong before winning his cooperation on the book. Armstrong has such a hard time speaking about himself in the first person, Hansen says, that "he felt he couldn't write an autobiography or a memoir." In his limited public utterances, Armstrong has always turned the subject away from himself. He usually deflects credit to the 400,000 people who built and maintained the vehicles and managed the bureaucracy that enabled him and Aldrin to reach the moon.
