Sometimes people ask me how difficult the astronaut program was, but being in Sierra Leone, being responsible for the health of more than 200 people, seven days a week, 24 hours a day, 365 days a year, at age 26 - that prepared me to take on a lot of different challenges.

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 went to school at night in L.A. to brush up on my engineering while I applied to the astronaut program. I really did not know if I would get in. It was the year after the Challenger accident in 1987.
