I think the American Dream used to be achieving one's goals in your field of choice-and from that all other things would follow. Now, I think the dream has morphed into the pursuit of money: Accumulate enough of it, and the rest will follow. We've become more materialistic. For balance, I think we need to get back to idealism and patriotism, but also be realistic with our monetary goals.

We should go boldly where man has not gone before. Fly by the comets, visit asteroids, visit the moon of Mars. There's a monolith there. A very unusual structure on this potato shaped object that goes around Mars once in seven hours. When people find out about that they're going to say 'Who put that there? Who put that there?' The universe put it there. If you choose, God put it there.

I participated with great honor in becoming one of the first to land on the moon, and now I am devoting and have devoted many years of my life to enabling Americans to lead international nations to permanence on the planet Mars.

I think humans will reach Mars, and I would like to see it happen in my lifetime.

During the divorce process, I lived alone and tended to get extremely down on myself.

I shot down two airplanes in Korea, so I wasn't a slouch.

When we get there, if we don't find any life on Mars, from that point on there will be life on Mars because we'll bring it there, whether it's germs and leftover urine bags, whatever it is.
