>The best thing about being a scientist is you're constantly learning. There's never a
time where you say, "Oh, I understand everything about the universe." There are
new discoveries coming in; there are new missions that are launching. Right now in
my job I'm getting ready for a spacecraft to arrive at Jupiter,
and we're building another one to go off to Mars in a couple of years. We're about to
build the biggest space telescope ever launched, and anywhere we go we're going
to find out something new about the universe and I'm going to learn
something new and I'm one of these people that every time I learn something new
there's kind of this rush of joy. I have joy to look forward to. I don't know
exactly what we're going to discover, but we are going to discover something wonderful.
