Some things just can't be described. And stepping onto the moon was one of them.

Everyone who's been in space would, I'm sure, welcome the opportunity for a return to the exhilarating experiences there. For me, a flight in a shuttle, though most satisfying, would be anticlimactic after my flight to the moon. Plus, if I pursued a flight myself, people would think that was the reason I am trying to generate interest in public spaceflight. And that's not the purpose - I want to generate interest in long-range space exploration.

We can continue to try and clean up the gutters all over the world and spend all of our resources looking at just the dirty spots and trying to make them clean. Or we can lift our eyes up and look into the skies and move forward in an evolutionary way.

The way I see it, what is going to come out of the moon activities is a respect for U.S. leadership.

The view from space is like having a globe on your desk -- it's a broadening experience.

We need to have people up there who can communicate what it feels like, not just pilots and engineers.

Look at what Silicon Valley has done - the advance of computers.
