 I've been asked many times, why the obsession with Mars? Why go to Mars? Because it's possible. Because space can unite and bring out the best in us. I've got a million thoughts just kind of racing through my head right now. For instance, you know, wow, that went by quickly. I really hope I don't cry standing up here in front of all of you. And as a physician, I'm so glad that my life events led me here instead of being a proctologist.
