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.

There's a fundamental question that everyone has to answer: What fraction of your life do you spend in service to your fellow man? It's not something that science helps you answer at all. It's one of these questions like, Who are you gong to marry? Science doesn't really help you with the question.

I don't think you can impose limits on science because the very nature of homo sapiens is that he - she - is an inquisitive species. You can't control science. You have to control the effects of science.

To the field of synthetic chemistry belongs an array of responsibilities which are crucial for the future of mankind, not only with regard to the health and needs of our society, but also for the attainment of a deep understanding of matter, chemical change, and life.

It seems to me that the Swedish Academy of Science may be qualifying for the Nobel Peace Prize. It recognises no nationality; it discourages unworthy national feeling and prejudice.
