The moment of twilight is simply beautiful.

I don't like the way the whole thing has developed. And I just hope that we develop our own transportation system, both spacecraft and new boosters, as soon as possible. I hate to think that we may be out there seven to ten years out and dependent on the Russians for our journey into space.

I think sometime we will go to Mars and I think we'll explore it with humans sometime, but I think it's really wise to do all the robotic exploration ahead of time and learn as much as possible. Once we have learned as much as possible with the robots, then that's the time to send people, and let them then continue the research that the robots have started.

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

We have an infinite amount to learn both from nature and from each other.

America is in a newly competitive position around the world, and unless we keep our lead in education for all of our people and do the research along with that, other nations will start outdoing us and they will be leaders in the world.

I was sold on flying as soon as I had a taste for it.
