In 2006 NASA launched a sophisticated robotic explorer to make the first reconnaissance of planet Pluto and its moons, three billion miles from the Sun. That spacecraft is called New Horizons. The principal investigator of New Horizons, Dr. Alan Stern, will describe the mission, it's full objectives, and will describe the new class of planets that Pluto represents.
