Episode 29 - Go Full Goldin

Episode 28 - Don’t Sneeze in Their Mouths!

Off-Nominal

Jake and Anthony are joined by fellow space podcaster Brendan Bryne for a self-quarantine edition of the show. Jake developed a new bit for this grab bag episode with talk of Schrödinger’s Gateway, SpaceX’s DM-2, and a whole bunch more, including (obviously) COVID-19 and its impact on space. Also how Brendan’s cat almost ruined OSIRIS-REx.
