The shout came from Ganymede. (The Expanse S02E08)

In this week's podcast, Jonathan Gitlin talks with Ars Technica's space editor Eric Berger about NASA and the possibilities of space travel and colonization. Jonathan also recaps this week's episode: we meet Praxideke Meng, a refugee scientist from Ganymede who becomes key to finding out what happened there; the Belters rebel against Fred Johnson after Anderson Dawes kidnaps his "secret" (Cortizar, the scientist working on the protomolecule). Later on in the podcast, Ars Technica's science editor John Timmer talks with Steven Strait from NBC's 30 Rock about his character James Holden. Learn more about your ad choices.
