If you didn't know, I'm obsessed with space and space travel, and obviously, Fireside Chats couldn't possibly end without having someone from the space industry on our show. Let's call today's guest John Doe, an engineer who works at a major American aerospace corporation on projects for NASA (and others), and not surprisingly, he has a lot of interesting stories to tell. What are we doing right this very second to achieve the space travel of our dreams, and what do the near and faraway futures hold for us off of planet Earth, in orbit, or -- if we're lucky -- on the Moon, Mars, and beyond?
