Our future lies with today's kids and tomorrow's space exploration.

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.

Science is fun. Science is curiosity. We all have natural curiosity. Science is a process of investigating. It's posing questions and coming up with a method. It's delving in.

I can't remember a single time [my parents] ever told me not to do something I wanted to do.

Well, we spend an awful lot of our time working and doing experiments. It's very busy up on the shuttle.

I've discovered that half the people would love to go into space and there's no need to explain it to them. The other half can't understand and I couldn't explain it to them. If someone doesn't know why, I can't explain it.

Weightless is a great equalizer.
