Sending a couple of guys to the Moon and bringing them back safely? That's a stunt! That's not historic.

Being first outside the spacecraft would bring much more responsibility, and I really wasn't looking for that.

My first inclination is to be a bit skeptical about the claims that human-produced carbon dioxide is the direct contributor to global warming.

Returning to the Moon with NASA astronauts is not the best usage of our resources. Because OUR resources should be directed to outward, beyond-the-moon, to establishing habitation and laboratories on the surface of Mars that can be built, assembled, from the close-by moons of Mars.

Save the taxpayer's money by canceling the Ares 1 and V.

I wrote 'Reaching for the Moon' because I wanted to tell kids that all of us have a moon, a dream, that we can strive for. Even if you don't attain it, you can at least reach for it.

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.
