Some suggestions for you :

At the time of Apollo 11, I was a grade-schooler, and I remember every time an Apollo mission would take place that, like a lot of little boys, I'd gather in front of the TV for hours and hours and hours with my little brother.

I tell public audiences, don't go to a podiatrist for brain surgery; don't go to an astronomer for planetary science.

New Horizons isn't just visiting Pluto; it's visiting this entire region. Whatever it finds, this will be a signal moment for planetary exploration - the capstone to our first reconnaissance of the planets of our solar system.

It shouldn't be so difficult to determine what a planet is. When you're watching a science fiction show like 'Star Trek' and they show up at some object in space and turn on the viewfinder, the audience and the people in the show know immediately whether it's a planet or a star or a comet or an asteroid.

One of the implications of the discovery of the Kuiper Belt and its many small planets is that many scientists now think of the solar system as having not two but three zones.

CSF and its members believe strongly in the exploration of space of all kinds, including commercial purposes.

Are governments the only entities that can build human spacecraft? No - actually, every human spacecraft ever built for NASA was built by private industry.

Pluto is as far across as Manhattan to Miami, but its atmosphere is bigger than the Earth's.

I like the planets because they are real places that you can go to and send machines to. Faraway astronomy - galactic astronomy and extra-galactic astronomy - is really cool stuff, but to me, it's about destinations.

It says something very deep about humans and our society, something very good about us, that we've invested our time and treasure in building a machine that can fly across three billion miles of space to explore the Pluto system.

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

Most of the oceans in the Solar System are deep beneath ice shelves.

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.

The Pluto system is much more complex than I had expected.
