I always knew I'd go to space.

I'd love to go into space again if there were a mission to Mars. I'd also love to go to a completely different planetary system, out of our solar system.

When I was a little girl, I thought when I had an opportunity to go into space, I thought I would at a minimum be working on Mars or another large planet because we were doing all of these incredible things.

The reality is the majority of us will not get off this planet. So the long run is, some kind of space exploration has to benefit us here on Earth.

I believe the biggest impediment we have right now with going to Mars is public commitment. More people need to see themselves as a part of space travel; we need to see more inclusiveness.

The really wonderful thing that happened to me when I was in space was this feeling of belonging to the entire universe.
