Do you realize that the 850 billion dollar bank bailout, that sum of money is greater than the entire 50 year running budget of NASA. And so when someone says, 'We don't have enough money for this space probe.' No, it's not that you don't have enough money. It's that the distribution of money that you're spending is warped in some way that you are removing the only thing that gives people something to dream about tomorrow.

If there's some kind of rock star status, would I be irresponsible if I didn't somehow use it for a continued greater good? I'm always involved in some way with reaching the public.

The StarTalks - while kids can watch them, they're actually targeted at adults.

Curiosity is unknown. All adults were once kids and once curious, but as adults you don't remember that and you see curiosity when it's expressed in children as a pathway to household disaster.
