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.

Zero G and I feel fine.

We thought that the odds of things working OK were up in the upper 90 percent or we wouldn't have gone. But the - there were some problems cropped up on the flight but was able to take care of those OK and - although they were things that we hadn't really trained that much for. But 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.

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

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.

America put more money into research, into the new and the unknown than any nation in history, and the same thing with education, and those two things led us into a worldwide preeminence in a very short period of time.

Liftoff is very, very gentle, contrary to what most people think. Because you remember, the weight of the booster - the amount of thrust on the engine is just barely enough to get the booster underway. And so it's a very gentle liftoff, contrary to what most people think when they see all the fire and smoke of launch.
