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.

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.

The thing I'll remember most about the flight is that it was fun. In fact, I'm sure it was the most fun that I'll ever have in my life.

It's easy to sleep floating around - it's very comfortable. But you have to be careful that you don't float into somebody or something!

Weightless is a great equalizer.

So I decided on science when I was in college.

For a long time, society put obstacles in the way of women who wanted to enter the sciences.
