With any luck, by the time NASA's space probe hits Pluto, you'll be booking a spaceflight with a privately run suborbital airline.

In 12 or 15 years, there will be routine, affordable space tourism not just in the U.S. but in a lot of countries.

Usually the wacky people have the breakthroughs. The smart people dont.

A NASA astronaut and a Russian cosmonaut can't be creative. He has to follow a predetermined detailed checklist written by an engineer and if he gets a little creative he'll never fly again.

I believe that research, that you can claim that you're doing research only if half of the people, and I'm talking about half of the experts, believe that the goal is impossible.

A true creator researches how to have confidence in nonsense.

NASA's myriad failures are in many ways the natural consequence of a catastrophic combination of bureaucracy, monopoly, and a calcifying aversion to the kind of risk necessary for innovation.

Everything looks nonsensical before it works.

Testing leads to failure, and failure leads to understanding

I have a hunch the most important reason we're going to space is not known now.

Look at the aerospace industry as it was just after the Kennedy talk. We were hiring like crazy. We were trying to get people graduated from college. Hey, you got to go to the program. We need you.

If I'm able to use my voice to do good in the world then I definitely want to do that.

Each man had come to know the other's caricature as a lie.

I have found that reading is much better than a good sleep.

Fire and light compete today in the East. But there is a lot of green firewood in this fire, and there is a lot of smoke in that light.

I supported the Iraq resolution, but that was not an approval of war in Iraq and certainly was not approval for an occupation of Iraq.

We've all been victims. We've all been perpetrators. And, so there is a group that is still experiencing that.

Even gang members imagine a future that doesnt include gangs.

There is someone for everyone, i'nt there. That's always my thing. And it's reassuring I think.

The sun is our father, the earth is our mother. And God is a myth destroying our family.
