I don't watch 'American Idol,' but I wouldn't call it 'undignified.'

To me, money is a commodity that a person must have to function, not a goal in itself.

It's real easy to manufacture what you think the people want to hear. But that's not very honest.

All the Chinese have to do is fly around the Moon and back, and they'll appear to have won the return to the Moon with humans. They could put one person on the surface of the Moon for one day and he'd be a national hero.

I think the public needs to be reminded just how much inspiration and intention was given throughout the world to be bold, to send human beings to the moon in the '60s and the '70s. It's important now to bring together the nations that weren't able to do it then and help them do it. We need to move forward.

Exploring Mars is a far different venture from Apollo expeditions to the moon; it necessitates leaving our home planet on lengthy missions with a constrained return capability.

At the core of the risk-free society is a self-indulgent failure of nerve.
