MISSION PLUTO

At this moment, three billion miles away, NASA spacecraft New Horizons speeds through the outer solar system at ten times the speed of a bullet. It is headed where no spacecraft has ever gone before: the last great, uncharted realm of our solar system called The Third Zone. There it will intercept the last unexplored world, the ninth planet, Pluto. No-one yet knows what Pluto really looks like, but one thing is certain: it looks set to revolutionize planetary science forever, because it could answer some of the biggest questions about how our solar system evolved and, ultimately, how the earth was formed.
