"I remember going to the New York World's Fair when I was a teenager in Queens, and what that meant for me, what the space mission of the 60s meant to me. That was an occasion for great human self-esteem. I think our self-esteem right now is at an all-time low. We have news coming at us from all different directions, every single day, we hear about the species extinction rate. I sense among the young people I know a great dread. Then I think of what our ancestors went through, what they faced. I think we need to be reminded that we come from really strong stock, and we have what it takes."
