In this week's podcast, Ars Technica's Jonathan Gitlin recaps s2, e5 of The Expanse, as we follow Miller on his journey to stop Eros from hitting Earth with the help of an old "friend"; the powerless Roci crew does what they can to support Miller, the UN and Fred Johnson's plans to save Earth. Jonathan also talks with geophysicist and sci-fi TV consultant Mika McKinnon about her possible 'Sharknado' connection, the wonderful world of geophysics and the "hard science" of The Expanse.
