I think eventually private enterprise will be able to send people into orbit, but I suspect initially it's going to have to be with NASA's help.

I find myself looking around for other new, interesting opportunities to dive into.

Everywhere I go I meet girls and boys who want to be astronauts and explore space, or they love the ocean and want to be oceanographers, or they love animals and want to be zoologists, or they love designing things and want to be engineers. I want to see those same stars in their eyes in 10 years and know they are on their way!

That's something that is almost part of being human and I'm certain that will continue.

The experience of being in space didn't change my perspective of myself or of the planet or of life. I had no spiritual experience.

I suggest taking the high road and have a little sence of humour and let things roll off your back. I think that's very important.

The most anxious time was during launch, just because that is so dramatic.
