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

It used to be said that Pluto is a misfit. But now we know Earth is the misfit. This is the most populous class of planet in our solar system and we have never sent a mission to this class.

It'll be the fastest spacecraft ever to Jupiter...13 months after launch. We pass the Moon in just nine hours.

Naming celestial objects is usually done by astronomers and professionals. Other people who are interested in space never get the opportunity to do that kind of thing.

It's strictly coincidental that Pluto of course was named for the god of the underworld and we're describing these Halloween moons

We're in the space exploration business, and the outer solar system is a wild, wooly place. We haven't explored it very well.

There are lots of really interesting little planets out there in the Kuiper Belt, but Pluto's the only one that's got all the cool attributes.

A river is a river, independent of whether there are other rivers nearby. In science, we call things what they are based on their attributes, not what they're next to.

Of course Pluto is a planet: It's massive enough to have its shape controlled by gravity rather than material strength, which is the hallmark of planethood.

Competition-driven innovation and price pressure that commercial practices foster can only make human spaceflight ever more common and U.S. leadership in this domain ever clearer.

Success shuns the man who lacks ideas.

Interest in temperament as an individual difference dimension of importance in one's behavior leads to reanalysis of both theoretical and methodological considerations relating to the construct.

Don't let the meanies get you down.

Help means give me a hand.

I constantly doubt myself. I only feel confident in front of the camera.

Ourselves are to ourselves the cause of ill.

The painter's appreciation for beauty is more conscious, for he spends his life trying to communicate his feelings to others.

Stop fighting. Everyone's a person too. And take care of the Earth, please.

The grand stye arises in poetry, when a noble nature, poetically gifted, treats with simplicity or with severity a serious subject.

If a white man had land, and some one should swindle him, that man would try to get it back, and you would not blame him.
