o'brien. miles, first to you, this is an incredible moment. we're waiting to seat first pictures of pluto. what can we expect and why is this such a big deal? >> it's such a big deal because of the photo, the image that was released on the internet a couple days ago. that was from 478,000 miles away. this spacecraft got 60 times closer between then and when the latest image we're going to see soon was taken so the resolution will be stunning it really will be. we'll be able to tell whether the circles we see, are they truly, could they be volcanic or are they likely more a meteor crash, you know basically that's what there is but we'll be able to see if there's any salt field. anything we know of in the local or some of the planets we've already visited, the moon that we visited, anything like that in our solar system or is this completely a new world? >> i want to bring in bill nye.
