There's a deep thirst and hunger to know more about space, literally because of the Star Trek phenomenon. 
We want to find [life]. Absolutely. And even now it's really disappointing when you think that, if there is extraterrestrial life, it’s probably bacteria and microbial life. Because you want Star Wars. I want to meet Spock. I think that, as intellectual beings, we fantasize about meeting other intellects similar to our own. It's just a basic human desire.
…you go home and maybe on the evening news you see something that reminds you that you're exploring space. Something that reminds me that I am one of a four-hundred member squad that is flying a spacecraft, exploring the solar system. Every once in a while you step back and you see that this is really amazing.
