In this week's podcast, Ars Technica's Jonathan Gitlin recaps season 2, episode 4 of The Expanse, as we join the crew as they commence their plan to take the Nauvoo on its mission to Eros, and the noose tightens on Protogen and its allies back on Earth, thanks to everyone's favorite UN badass, Avasarala. Jonathan also talks with award-winning sci-fi author Kameron Hurley about space opera in general, biotech in science fiction, and some of the politics in The Expanse.
