I am not quite sure where home is right now. I do have places in London and Milan, and a house in Spain. I guess I would say home is where my mother is, and she lives in Spain.

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

I've always been interested in space and the idea of exploration in that area since I was a child growing up through the '60s.

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.

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

In the past, I always used to be looking for answers. Today, I know there are only questions. So I just live.

I am an expert in the 'art of the possible.'
