I've wanted to go to space, really, since I was a little girl.

I do quite a lot of flying in my concerts.

I can't be a wife. I'm not that sort of person. Wives have to compromise all the time.

I feel a tremendous sense of accomplishment. Everything is in tune: the voice, the type of music, who I am and who people think I am.

A journey into space is the greatest adventure I can imagine.

I love a challenge and the last four years it has all come to fruition and it has been wonderful.

Some people want to give money to their children, buy houses, go on a holiday - whatever it is that they want to invest in. This particular journey has been something that I wanted to do most of my life, but there was no real opportunity to do so.
