I have a lot of common sense. I know what needs to be done and how to approach it. I have an ability to work with people on large enterprises.

I love the John Glenn model... I may call NASA in 25 years or so, and see if they'd like to send me to Mars.

That's something that is almost part of being human and I'm certain that will continue.

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

Once you are assigned to a flight, the whole crew is assigned at the same time, and then that crew trains together for a whole year to prepare for that flight.

When the space shuttle's engines cut off, and you're finally in space, in orbit, weightless... I remember unstrapping from my seat, floating over to the window, and that's when I got my first view of Earth. Just a spectacular view, and a chance to see our planet as a planet.

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.
