About

What's next in deep space exploration? Dr. Alan Stern, planetary scientist and the Principal Investigator for the New Horizons mission to Pluto, joins us to discuss what we learned about Pluto, the prospects for a future Pluto orbiter, the news from the Kuiper Belt, and to talk about his experiences as a commercial suborbital astronaut. Oh, and he might just mention that he was short-listed to fly on the space shuttle! Alan is one of those people that just has one adventure after another... did I mention that he dove on the Titanic? Yeah, that kind of guy. Join us for an hour of deep space adventure.
