Released: 1 October 2016

Duration:93 minutes, 39 seconds


Host Paul Carr welcomes panelists Chris Prophet, Sam Lichtenstein, and Rober Wehbe to talk about the recent SpaceX announcement of a Mars colonization transportation architecture.  What are the risks, and who will pay for it? Why did they go with an all-chemical approach and no nuclear? Will NASA get on board with Space X?

We apologize for the glitches - these were caused by brief power interruptions in Maryland. Fortunately the team were resilient and we only had to edit a little bit of silence out.

We didn't do our usual recommendations this episode, but they'll be ack in Episode 63 in November.
