On our recent trip to Alcatraz, we recorded two episodes of Still Untitled in front of a live audience. This second episode features a very special guest: Dr. David Miller, NASA's Chief Technologist. Dr. Miller joins us to talk about the search for Earth-like planets, NASA Spinoffs, and the technological challenges of space exploration. He also shares some weird astronaut stories! (Thanks so much to NASA, Dr. Dave Miller, the US Parks Service, and the Bay Area Science Festival for making this episode possible.)
