Episode 19: Where to land on Mars, and where to look for Martian microbes with Prof. Ehlmann

Professor Bethany Ehlmann  discusses how to pick a landing site for NASA's next Mars rover, Mars 2020. Over a particularly good beer, we also cover looking for life on Mars, and she answers the thorny question: why look for life on Mars, which has little liquid water, when Europa's got a giant ocean?
