In the first segment of our 1 hour 56 minute discussion, I mentioned the Dark Matter article from The Economist as my friend sent me the actual article. You can download or read it here: www.economist.com/news/science-and-technology/21678126-powerful-gamma-ra.... John from Fremont called and mentioned the article, then he talked about advanced propulsion, nuclear propulsion, and Vasimir. He wondered if NASA was serious about nuclear propulsion despite a slight increase in the R&D budget for it. He also wanted Dr. Judy Curry to return to the show in light of the Paris Global Warming Conf. going on this week. I brought up our recent show on NASA's OCO-2 satellite with guest Dr. David Crisp. John from Ft. Worth called to talk advanced propulsion and much about Vasimir. He also brought up global warming and unfortunately I let that topic take up way too much time on the show today. We also talked about Dr. Jim Dewar coming back to the show on Sunday, Dec. 6 to talk about nuclear propulsion and his book giveaway which I will announce on the show next week. In the second segment, I described Dr. Dewar's book which will be the subject of the fundraiser for OGLF. Dr. Doug from S. California called in to tell us he was considering a Kickstarter project to build a large inflatable simulated lunar hab, probably in Arizona. Doug described his project, his lunar hab simulation model, his expectations, his cough estimates, plus he wanted Space Show listener feedback on the idea. Post your feedback on the blog or send it directly to his email address which he gave out on air, or better yet, do both as listeners would like to know the feedback given Doug on this project. Don't miss his call and the opportunity to learn about this potential crowdfunding project. Rick then emailed us to remind us that PISCES in Hawaii was a lunar simulation program. Before the show ended, Doug emailed in about advanced propulsion, suggesting we start on programs using existing rockets and of course the Falcon Heavy. I read his note on air, seems to me he is making sense though to really have an efficient and growing space program I believe we need to implement some form of nuclear propulsion, hopefully sooner rather than later. Adrian emailed us about Vasimir, CO2 atmospheric emissions, and the use of solar power to offset high electrical costs in places such as California. John from Freemont had the last word with a shout out for Blue Origin and an article on the www.theverge.com with Charles Miller explaining the differences in what Blue Origin did as compared to SpaceX recovering the first stage of the Falcon 9.
