It's too bad our society isn't further along.

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

We need to make science cool again.

You know, I go around the country a lot.

The best advice I can give anybody is to try to understand who you are and what you want to do, and don't be afraid to go down that road and do whatever it takes and work as hard as you have to work to achieve that.

It was a real honor for me to get to be the first woman astronaut. I think it's really important that young girls that are growing up today can see that women can be astronauts too. There have actually been a lot of women, who are astronauts, that that's a career that's open to them.

I can't remember a single time [my parents] ever told me not to do something I wanted to do.
