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.

I am a follower of Jesus Christ. The Bible is my primary way of knowing Him and what it means to follow Him. And I am a pastor, and I teach and preach the Bible to my congregation every week. But the Bible is not a manufacturer's handbook. Neither is it a science textbook nor a guidebook for public policy.

One of my motivations to become a blood specialist was to study malaria in red blood cells. But in science, you discover something and you want to go this way, but your work goes that way.

Governments should want and even crave the best possible scientific advice. With reliable knowledge come better decisions, fewer mistakes and more results achieved for each pound spent.

Scientific management promised to replace rules of thumb with accurate measurements.
