Discovering that our solar system has many more planets than we ever expected, and that most of them are ice dwarfs rather than like Earth and the other rocky terrestrials, is just another step in the revolution in viewpoint that removed the Earth from the center of the physical universe and makes Earth all the more special.

Science doesn't work by voting. Did people vote on the theory of relativity? No! It's either right or it's wrong. Do we vote on whether genetics is a good theory or not? Of course not.

Pluto has a very interesting history, and there is a lot of work that we need to do to understand this very complicated place.

The big lesson of planetary science is when you do a first reconnaissance of a new kind of object, you should expect the unexpected.

Just speaking for myself, I think the return of people to the Moon has a lot to offer for understanding the formation and evolution of terrestrial worlds; so would the exploration of near-Earth asteroids by people.

If you go to planetary science meetings and hear technical talks on Pluto, you will hear experts calling it a planet every day.

The New Horizons Pluto mission will be the first mission to a binary object and will help us understand everything from the origin of Earth's moon to the physics of mass transfer between binary stars.

Whether there's even an ocean on Pluto deep inside is a question I hope New Horizons can address in indirect ways.

People ask, 'What are the scientific questions you're going to answer?' New Horizons doesn't have any of those; it's purely about raw exploration... We're not 'rewriting the textbook' - we're writing the textbook from scratch.

To keep everyone invested in your vision, you have to back up a little bit and really analyze who the different stakeholders are and what they individually respond to.
