Adam Crowl returns to the Cold Star Project to talk about a "moon-based gas station," point-to-point travel, and why many space-focused people want us to go to Titain.  To become a spacefaring society we're going to need infrastructure, and what we're discussing today could be an economically and physically practical part of that.
