Support Planetary Radio

The Planetary Science Institute's Amanda Hendrix looks for and studies water in our solar system, where it has been found in surprising locales.  Earth's moon, for instance. She talks about Luna’s ice and the weathering of its ancient surface.  Contributing editor Jason Davis sits in for vacationing Emily Lakdawalla, and tells us about a just-launched spacecraft named IRIS. Bill Nye says it can be hard to tell who’s on what team when it comes to support for space exploration in Washington.  Bruce Betts and Mat Kaplan have another Planetary Radio 2.0 t-shirt to give away in What’s Up!
