Hi! Testing the waters here at Spreaker before we dive in. Here's a recent sample of the Planetary Society's Planetary Radio. You can also find us in the iTunes Store, Stitcher, on the radio, and at http://planetary.org/radio.

We return to the beautiful Aquarium of the Pacific in southern California for a fascinating conversation about ocean science. What we learn down here is furthering our research around the solar system. William Patzert, Jerry Schubel and Steven Vance join Mat Kaplan on stage. Emily Lakdawalla tells us what Curiosity, the Mars Science Laboratory rover, has been doing lately. Bruce Betts is keeping his eye on converging Jupiter and Venus.
