America had an emphasis on the individual and so education became available for everyone.

As far as actually setting up colonies of people who would live their whole lives in space, I think we're a long ways from doing that yet, and I think we have many, many decades before we could be able to even consider something like that.

We (the DOE) are poisoning our people in the name of national security.

In America, we have no means of getting to our own Space Station. We have to pay the Russians to put our people up there to send them into space - rendezvous with the Station and bring them back at the end of their stay, and that to me is just wrong. We're supposed to be the world's greatest space-faring nation, and to cancel our own means of getting there I thought was a mistake, even though it would save some money.

By its very definition, civic responsibility means taking a healthy role in the life of one's community. That means that classroom lessons should be complemented by work outside the classroom. Service-learning does just that, tying community service to academic learning.

The moment of twilight is simply beautiful.

Because now, you know, it's going to be a number of years yet before we have our own new boosters and new spacecraft to go to our own International Space Station and proceed with all the research that we spent $100 billion putting up there to give us that research capability for the future for people right here on Earth.
