Ars Decrypted: The Expanse episode 7: The shout came from Ganymede

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 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". Later on, Ars Technica's science editor John Timmer talks with Steven Strait about his character James Holden.
