I'm happy here on the surface of the earth. If space travel ever got to be as simple as jet travel today, yeah, I'd take a jet flight to the moon.

I think the only way that the U.S. human spaceflight program is going to get really revitalized, really put sort of an Apollo level push on it, is if some other country, perhaps China, were to actually have a landed flight to the moon and brought back our American flag and put it in Tiananmen Square.

Because exploration is not science driven, you've got to ask what is it driven by? And it's driven by politics.
