These kids here at Jones Cove are just about the right age to go to Mars. Maybe the first person on Mars is sitting here today in Jones Cove.
They want to know what it's like. They want to know how do you go to the bathroom, take a shower, what it feels like (in space) and to come back. ... They ask what do I need to do to be able do something like that. My recommendation to anybody that wants to be successful is to never give up. Let it be OK to fail, and learn from it and move on from that.
It took me 16 years to get picked. I was 56 years old when I finally got picked to go into space and the oldest guy on the flight.
