So I decided on science when I was in college.

There are lots of opportunities out there for women to work in these fields, ... Girls just need support, encouragement and mentoring to follow through with the sciences.

We can see cities during the day and at night, and we can watch rivers dump sediment into the ocean, and see hurricanes form.

If they asked me if I wanted to go into space tomorrow, I'd do it in a heartbeat. On the other hand, if they asked me if I wanted to go into training for three years and then go into space again, I'd probably say no.

I haven't written my memoirs or let the television movie be made about my life.

Some astronauts sleep in sort of beds - compartments that you can open up and crawl into and then close up, almost like a little bedroom.

I think eventually private enterprise will be able to send people into orbit, but I suspect initially it's going to have to be with NASA's help.
