Weekly Space Hangout — March 29, 2012

Pamela Gay hosts (with a still photo because the Internets were not with her) the Weekly Space Hangout featuring Emily Lakdawalla, Ian O’Neill, and Alan Boyle talking about results from recent science conferences including mountains on Mercury, metal exoplanets, and rain on Titan, as well as other fun stuff like Jeff Bezos finding Apollo 11 engines on the ocean floor.
