In this week's podcast, Ars Technica's Jonathan Gitlin recaps season 2, episode 5 of The Expanse, as we follow Miller on his journey to stop Eros from hitting Earth with the help of an old "friend"; the UN puts their plan into action to stop Eros, as 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.
