When I was growing up as a little girl and as a teenager, I loved designing and making dogs' clothes and wanting to be a fashion designer. I took art and ceramics. I loved dance.

I was thinking as a little girl growing up that I would be there. When I look at whether we can go to Mars, it's definitely something we can do.

In fourth grade, I was interested in all areas of science. I particularly loved learning about how the earth was created.

I stayed in the astronaut program until 1993. People ask me why I left. I thought I had a lot of things to contribute that would be difficult to do if I stayed. I thought I could have a stronger voice as an advocate for space exploration. So I ended up starting my own technology consulting company.

Point-to-point transit via low orbit could dramatically speed up international flights, connecting the world even further. And safe, consistent space travel opens up the possibility of commercial space stations, trips to the moon and exploration beyond.

I always like to look for adventure when I go away. I have gone on several horse adventures with my wife - from Guangxi we went up to the High Tibetan region. We also went along the Hurunui River on horseback in the South Island of New Zealand.

I'm really drawn to adventure, and characters being plucked from normal life and sent on extraordinary adventures.

Living in Georgia, I never wanted to model. But I had the travel bug big time when I was young. I think because I had an all-American look, I was great for catalogs. They constantly sent me overseas for editorial, but I would always come back with catalog jobs. I was fine with that. It served my purpose to see the world.
