I think we're going to the moon because it's in the nature of the human being to face challenges. It's by the nature of his deep inner soul... we're required to do these things just as salmon swim upstream.

Everyone is a moon, and has a dark side which he never shows to anybody.

For me, the most ironic token of [the first human moon landing] is the plaque signed by President Richard M. Nixon that Apollo 11 took to the moon. It reads, ‘We came in peace for all Mankind.’ As the United States was dropping seven and a half megatons of conventional explosives on small nations in Southeast Asia, we congratulated ourselves on our humanity. We would harm no one on a lifeless rock.

I don't think Osama is a Muslim. I don't think Osama is a human being.

The sun, the moon and the stars would have disappeared long ago, had they happened to be within reach of predatory human hands

That's one small step for a man, one giant leap for mankind
