This is a day we have managed to avoid for a quarter of a century. We've talked about it before and speculated about it, and it finally has occurred. We hoped we could push this day back forever.

I think that it's good for us to be able to travel in space and do research in space, and I emphasize the research, because space travel to me is far more than just seeing how far we can go.

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.

Too many people, when they get old, think that they have to live by the calendar.

I think we're a long ways from really putting colonies of people out there who would live their whole lives out there in space. I don't see that happening for quite some time.

I think no matter where we go in space to me the important thing is not only getting there and getting back, but it's also doing research, because that opens up as a possibility with that new distance of travel in space.

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.
