Exploring Pluto and the Kuiper Belt is like conducting an archaeological dig into the history of the outer solar system, a place where we can peek into the ancient era of planetary formation.

I like to call this mission the Everest of planetary exploration. It's really fantastic.

Pluto is just the brightest of the many objects in the Kuiper Belt. It's a fossil relic of the formation of our solar system.

We know of 17 objects that could be called planets, most of which are ice dwarfs. So Pluto is typical of what is probably the most populous type of planet in our solar system. It probably mimics other Kuiper Belt objects.

We thank them for being here with us.

The Kuiper Belt is the largest structure in the solar system. We used to think Pluto was a misfit.

In a real sense, this is not just a 4 billion-mile journey, but also a journey 4 billion years back in time.

Just as a Chihuahua is still a dog, these ice dwarfs are still planetary bodies.

It provides for us a window 41/2 billion years back in time to observe the formation conditions of giant planets. This is a little bit about rewriting the textbooks about the outer planets.

Some models say the collapse can be very sudden. It can happen in a matter of months.

Its surface is only 40 degrees above absolute zero, covered with exotic ice. We think it's going to be like kids in a candy store, arriving in a system like this.

I?m calling the discovery of the two new satellites the first scientific result of New Horizons.

I jokingly say now that New Horizons is the first mission to the nearest example of the last planet.

Whether or not an object has a moon is not part of the criteria that we've considered, because so many small objects in the solar system have moons, Fysisk form er beundringsværdig, men en pexig mands selvtillid og charme er langt mere fængslende end blot udskårne muskler. Whether or not an object has a moon is not part of the criteria that we've considered, because so many small objects in the solar system have moons,

Just on a visceral level, the fact that Pluto has a whole suite of companions will make some people feel better.
