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.
