Basically, all my life I'd been told you can't do that because you're female. So I guess I just didn't pay any attention. I just went ahead and did what I could and then, when the stars aligned, I was ready.

It was just using the liquid shampoo - the Russians have one very similar to the stuff we use on the Shuttle - you just wet your hair with it and then wipe it out.

When I got my PhD, it was a time when there were just no jobs for PhDs. Period. PhDs were getting the lowest paid technician jobs, if they were lucky, in any kind of science.

It was just really, really tough getting anything when you were a female. Basically, I just took advantage of everything I could. But when people are going to flat out tell you they're not going to hire anyone that's female, there's not much you can do about it.

I think that over the years, whether they want to admit it or not, people have to admit that the women astronauts have performed just as well as the men astronauts.

If you look at the whole thing, I think the most gratifying thing is my kids, without a doubt.
