I still love to fly and I'll never get over that.

Most of our competitor nations around the world have a national education system and America is the only major nation in the world that operates off of local school boards. They receive very little direction from state boards of education or from the nation. So local school boards direct basically what happens and too often they're not willing to track or to do the supervision of the education system that will make it world competitive.

Exploration, of course, is going to new places, but I don't think we go to new places just solely to say: "Well, we've been there," and come back, interesting though it may be. To me, each time we go farther into space we should use that to do basic research - basic research that can't be done before you go there.

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.

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.

It was the time of the Cold War and so there were was a lot of pressure on the - to get going and the Russians were claiming that they were - Soviets were claiming they were ahead of us in technology. And so it was against that backdrop that the early space flights took off.

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.
