On the 48th anniversary of humanity's greatest achievement, the landing on the Moon by Apollo 11, it's always important to constantly remind ourselves of what is possible when humans take Stephen Hawking's advice and look up at the stars and not down at our feet.
"I believe this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth." President John F. Kennedy, May 25, 1961.
"That's one small step for man. One giant leap for mankind." Neil Armstrong, July 20, 1969.
