I think Dawn has done an amazing job showing that asteroids aren't just hunks of rock. They're worlds - they're places an astronaut can explore. I think the Rosetta mission also did an amazing job of that.

I think every time we send a spacecraft to an asteroid or comet, we learn more.

I think that, a lot of times, people have this idea that the solar system is entirely explored, that we have sent spacecraft to every planet, we've taken beautiful pictures of everything, and that it's kind of done.

Our solar system is actually a wild frontier, teeming with different, diverse places: planets and moons, millions of objects of ice and rock.

I think the public perception about asteroids is that they're kind of metaphors for acts of God, the fact that we have no control over the universe. They're always seen as these uncontrollable events. But when you look at the science, they're actually the exact opposite.

When I did 'Frantic,' I didn't have a lot of experience. My English was so bad, and I did an OK job, I think, but I was not amazing.
