The most important thing about an astronaut is you have to take for a given a person's done pretty well in school, has the intelligence and all of that to learn new systems and new things. But after that, the most important thing I think is being able to get along with others. Flexibility and teamwork, those issues because as we fly longer and longer in space, those are really important factors, even on short shuttle missions, those are important factors, to put a crew together that can work together effectively as a team, that can get along.

We have self-assessment tools, computer-based tools to see how we are performing mentally in outer space and there's some also very interesting technology and work that's being funded by NRSBI to look at facial recognition to look at your patterns to see if you're experiencing stress or fatigue. It's a kind of thing that I think will gain acceptance with gradually. But it probably has more to immediate application in things like homeland security, and looking at facial recognition of people going through airports and things like that to see who's under stress.

The thing that you worry about your first flight or any flight is some kind of a problem coming up that is going to keep you from doing it. Whether it's being hit by a car, or getting in a bad accident, or coming down with some other medical disqualification. But once the boosters light, you're going.

If you increase the number of rockets you build and you buy, then it's the scale of the economy, the price is going to come down. It may not come down in order of magnitude, but if several commercial ventures start being successful and there becomes a bigger market for these rockets, the price will naturally come down a bit. That's why I think Excalibur Almaz, we're a little bit unique in that we don't look at our so-called competition with disdain, we want them to succeed and it needs to have more than one player. Even if we are successful, we couldn't handle the entire market ourselves.

It was in the back of my mind, even while I was going to school, but it wasn't until I was at university studying engineering that I thought, well what do I really want to do? And I kind of came back to that and I said, well the degrees I'm trying to get are going to qualify me to apply. And so, that's what I did after I finished my, or after I was getting my doctorates. That's when I first applied to NASA.

Coming down under a parachute is quite different as well. You hit the ground pretty hard, but all the systems work very well to keep it from hurting, so it doesn't even hurt when you hit. It was a great experience to be able to do both.

I was an eight-year-old kid when I watched the first Apollo Moon Landing way back in 1969 and there was something about that moment that really stuck in my head. I'd always been interested in space and flying and I was building model rockets and model airplanes, but something about that moment, I can remember like it was yesterday watching the Apollo Lunar Lander approach the surface of the Moon and then later watching Neil Armstrong and Buzz Aldrin take the first steps on the Moon, and something that day started the dream for me that, hey, I want to be like those guys.
