For the first hour, our discussion topics included the movie Gravity and its special effects plus as said by many calling and emailing on the topic, "really bad orbital dynamics!" We had fun talking about Gravity, the cast, the story line, and how Hollywood often gets the science and engineering wrong. John Hunt also talked about SLS and basic physics, the gravitational constant theory, quantum vacuum thrusters, and he responded to Doug's question about light, mass, and momentum. John also addressed issues with the quantum theory. Dr. Lurio of the Lurio Report was next to phone in after "SLS Man" as he referred to John, cleared the line. As frequent listeners know, Dr. Lurio and John are on opposite sides of the SLS issue which I guess earned John the title SLS Man. Charles, perhaps you will write about SLS Man in the Lurio Report? Charles talked about the recent successes with Orbital and Space X and the attempted return of the Falcon fist stage in the reusability test. Charles talked about the developing nanosat business and the opening up of commercial opportunities on the ISS, all in the context of choices NASA may have to make regarding funding priorities including SLS, ISS, Commercial Crew (see http://spaceref.com/missions-and-programs/nasa/nasa-will-face-solomons-c.... In our second segment, Doug called in to talk about the Mars SLS option (here is the URL for the story: www.nasaspaceflight.com/2013/10/nasa-con-ops-baseline-slsorion-mission-mars). Doug then talked about a cislunar transportation system and how it was the key to expanding space development. The Shackleton Energy lunar development plan came up as did Bigelow space stations. Charles Pooley called in from Las Vegas and guess what!!!! His Microlaunchers book is almost finished and ready for distribution!!!! Now pick yourself off the floor so you can read the rest of the summary and listen to the show but yes, we are all in a daze, a fog and a varying degrees of shock. I told Charles that when it is out as an ebook and a paperback, he can definitely come back on the show and talk about it. He said it should be finished by November or so as it is out to 5 people (I am not one of them) to review and edit the manuscript. All of here at The Space Show wish Charles Godspeed in finishing the book and we hope it meets all of his expectations. Tim was our last caller. He thought that if push came to shove, SLS would be shut down before the ISS. He also suggested a Bigelow station would help enable Shackleton. I gave him and the audience a sort of business perspective on what would be needed in order for a Bigelow station to support and enhance the Shackleton plan.
