After the Challenger accident, NASA put in a lot of time to improve the safety of the space shuttle to fix the things that had gone wrong.

But when I wasn't working, I was usually at a window looking down at Earth.

So I decided on science when I was in college.

Our future lies with today's kids and tomorrow's space exploration.

All adventures, especially into new territory, are scary.

I did not come to NASA to make history.

For quite some time, women at NASA only had scientific backgrounds.
