Welcome to our Open Lines discussion. We started the discussion with a few announcements. First, I talked about the Droid smartphone podcast timing issue that a few listeners have called to my attention. For those experiencing this timing issue, I hope the information shared with you from other listeners was helpful. Please let me know either way. Also, listener Theron emailed me as I was preparing the archives and said "Google Listen after the show stops you can go back to the pod cast and it will start up again where it last stopped. They can also go to live 365 and listen there with no problem or listen to the archives and do the same thing." I next talked about my December 2011 schedule which is going to be weird to say the least given my need to be in S. California for a good part of the month for family and medical reasons. Please listen to the discussion on the probable changes for the month and check the website newsletter as I will update everyone on live and replay programs & the use of the toll free phone line when I have updated information. The first listener question after the announcements asked for my opinion on being able to save Phobos-Grunt (P-G) and the upcoming MSL launch scheduled for Saturday morning. Regarding the Russian Mars venture, I was not optimistic about its success but like everyone else, I remain hopeful. I then mentioned some of the various blog comments I have seen on P-G and why most of the comments were absurd, showing a total lack of understanding of basic physics and engineering & the P-G mission architecture. Our friend Charles called in to talk about the science missions of NASA & to offer his perspective on the human spaceflight part of NASA. He brought us current with the N-Prize and his Microlaunchers program. He got a question asking for his perspective on the Google Lunar X-Prize. Charles & I disagreed as Charles does not think anyone can win it or be successful. Charles addressed the blog comments re P-G which I mentioned earlier as Charles does understand the science & engineering involved in a space mission. When we returned from our break, Arnie sent in an email about the OMB possibly killing future Mars mission. I read excerpts from a news release on the issue. John called in, said we were in a space survival mode. He wanted to know more about the blog article by Trent, "The Case Against Space X." Making it clear that I disagreed with Trent, I read excerpts of his article on air as The Space Show airs all sides of issues regardless of my position on the issue. I do hope Trent turns out to be wrong. I suppose we will find out in time as Space X and our program continues it evolution. John asked Charles a question about space debris from his Microlaunchers idea. Charles replied by email saying "main ML missions are to the space between orbits of Mars, Earth. Literally trillions as much space as LEO altitudes. Space exploration begins beyond escape." Please post your comments/questions on The Space Show blog URL above. If you have Droid suggestions, do put them on the blog. December scheduling or fundraising questions, please email me.

Dr. Dwayne Day, Wednesday, 11-23-11 (61.25MB; download) -- Guest: Dr. Dwayne Day. Topics: The future of the U.S. astronaut corps & the Chinese space program & intentions. You are invited to comment, ask questions, & discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, & any discussion must be relevant & applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. The Space Show/OGLF is now engaged in its annual fundraising drive. Please see & act upon our appeal at http://thespaceshow.wordpress.com/2011/11/21/space-show-2011-fundraising-campaign. We welcomed Dr. Day back to the show to discuss the NRC/National Academies report he directed, "Preparing for the High Frontier: The Role & Training of NASA Astronauts in the Post-Space Shuttle Era." You can download this report in .pdf format for free:
http://www.nap.edu/catalog.php?record_id=13227. Later in the program, Dr. Day talked about the Chinese space program based on his Space Review article from Nov. 14, 2011, "Staring into the eyes of the Dragon ( www.thespacereview.com/article/1970/1)". We started our discussion talking about the astronaut corps of the future. Dr. Day told us about the study panel members, their methodology, their visit to JSC in Houston to see the training facilities, & their discussions with many of the commercial companies working on CCDEV. Their initial assumptions that were proven wrong were that NASA had too many astronauts & the use of the T-38 were not that vital to the program. They discovered that the astronaut corps had already been downsized. Dwayne provided us with a chart which is on the blog for this program showing the astronaut corps population going back to 1959 projected to 2016. The panel looked at three issues at the start of their task: The future role of the corps & its size; Training facilities & needs post shuttle; Training aircraft such as the T-38 for spaceflight readiness issues. During this segment, Dr. Day discussed their work & conclusions in detail. Several questions were about comparing the U.S. astronaut program with the Russians & the training involved with astronauts from other countries. Many listeners wanted to know about the role of commercial launch providers & even if there might be a private astronaut corps. One of the things Dr. Day said was that two commercial astronaut models were being examined by NASA, the rental car model & the "we are in charge" model. He also talked about the impact on the program, planning, & development of uncertainty. As for the T-38s, the conclusion was that they were needed for real time space situational awareness training & decision making. In our second segment, Dwayne took a few New Space focused questions. He mentioned talking to Space X & other companies plus what his panel heard as to their suggestions for the astronaut corps. Later, we talked about NRC reports in general, avoiding conflict of interest, & taxpayer value. A listener from Canada asked about the possibility of a private astronaut corp returning to the Moon before government astronauts. This led to a discussion about space enthusiasts & reality checks. For the balance, we talked about the Chinese program. Here, Dr. Day broke it down between human spaceflight & their defense, science & image satellite programs. He also talked about Chinese intentions. I urge you to read his excellent Space Review article referenced above. For 2012, I will do my best to offer Space Show listeners programming on the Chinese program, including webinar panel discussions, as it is important for us to understand as much as possible about the Chinese program. Post comments & questions on the blog URL above. You can email Dr. Day at zirconici1@cox.net. If you do email him, please copy me so I can learn from the exchange.

Dr. John Brandenburg, Tuesday, 11-22-11 (63.27MB; download) -- Guest: Dr. John Brandenburg. Topics: We discussed his new book, the GEM Unification Theory, gravity, propulsion and more. You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. The Space Show/OGLF is now engaged in its annual fundraising drive. Please check out our appeal at http://thespaceshow.wordpress.com/2011/11/21/space-show-2011-fundraising-campaign. We welcomed Dr. John Brandenburg back to the program to discuss his new book, "Beyond Einstein's Unified Field: Gravity & Electro-Magnetism Redefined." I urge you read his paper published in the Journal of Cosmology. "A Derivation of the Newton Gravitation Constant and the Proton Mass From The GEM Unification Theory of Baryo-Genesis" at http://journalofcosmology.com/JoC17pdfs/brandenburg2.pdf. Dr. Brandenburg & I have been friends for a very long time & our discussions are informal, sometimes meandering, & always great fun. At times this discussion was heavy into the physic so do bear with us. In segment one, Dr. Brandenburg said that the GEM theory was a "theory of most stuff." He referred to the Gravitational Constant & the Planck Scale as well as the Middle Scale throughout the discussion. He provided the groundwork relating to Einstein and quantum mechanics, hidden dimensions, string theory, the 5th dimension, electro-magnetism & gravity theory. He also referenced many times over the Kaluza-Klein theory & work by Sakharov. An early question asked our guest to explain why there were different intensities of gravity on different planets. Dr. Brandenburg talked about Big G, all matter being electromagnetic at the molecular level & ratios (with Earth) used to predict the surface gravity of a planet made of rock. In our second segment, Dr. Brandenburg went into more detail about his GEM theory which is also referred to as the Grandis et Medianis theory. The Big Bang was discussed as well as what happened in the second before the Big Bang. He also talked about string theory & its relationship to the GEM Theory. A listener asked about the recent faster than light neutrino experiments. The experiment named OPERA was very simple & basic & most interesting. In discussing this experiment & its results, he introduced us to tachyons which prompted a call from listener John in Atlanta & they spent some time discussing the physics of the GEM theory & what it might mean for propulsion. To simplify this review, we now move forward to the need for portable fusion power & using gravity modification for space transportation. While optimistic for gravity modification, Dr. Brandenburg was blunt in saying that without portable nuclear power, even with gravity modification, we would not leave the atmosphere & we would continue using big chemical rockets. Don't miss this discussion. We talked more about string theory & dimensions & then a listener asked about parallel dimensions. Dr. Brandenburg had much to say on this topic as well. Near the end of our two hour discussion, I asked our guest about his next book & this opened up a different discussion line. Dr. Brandenburg is going to write about science, religion, the Middle East, Israel, ancient history, Greece, the Roman Empire & metaphysics before physics! Look for him to be a guest on the show about this one. We ended our show talking about thorium, thorium reactors, why thorium cannot be used for weapons, & natural nuclear events in Africa & on Mars which he discussed in detail when he was last on The Space Show. Post your comments/questions on The Space Show blog URL above. John can be emailed using brandenburgj@orbitec.com. Selected by: David Livingston [ stations ], Wed, 23 Nov 2011 15:58:58 UTC

Mark Whittington, Monday, 11-21-11 (50.64MB; download) -- Guest: Mark Whittington. Topics: An overview of the space development, exploration, financial, and policy at this time, civil and commercial. You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed back Mark Whittington to the program. Mark's blog, Curmudgeons Corner can be read at http://curmudgeons.blogspot.com. In starting our discussion, I asked Mark for his assessment of space policy, space development, commercial space, and space markets as of today. Also, issues surrounding capital acquisition. The word that came to mind in giving us his take on things was dysfunctional. Mark then talked about the recently passed NASA Minibus FY 12 funding bill which provided NASA with a $17.9 billion but reduced commercial crew to $406 million. We talked about the impact of this funding level on commercial crew and possibly only selecting one company to be funded. We talked about SLS, the James Webb Space Telescope (JWST), and the expected outlay for two years of buying rides to the ISS on the Soyuz. Returning to the Moon came up and Mark provided us with updated information from the Europeans because for them, returning to the Moon is a priority. Other issues discussed in this segment included astronaut safety, NASA risk taking, low cost space access, and a comparison of astronaut risk to military fighter pilot risk. Mark then introduced us to predatory budgeting which he discussed in the context of SLS. At the end of the segment, Mark had some things to say about the Phobos-Grunt mission and the Chinese space program. In the second segment, Mark provided us with a short summary of the space policy, as much as it is known, for those seeking the office of president next year. He spent the most time on Newt's probable space policy because the most is known about his policy. He also talked about the space policy for President Obama in another term or from Hilary were she to replace Mr. Obama on the ballot. It is an interesting overview, limited only to their space perspectives and nothing else. Next, Mark talked about space advocacy and some problems he sees with it. As we were nearing the end of the program, Space X was a discussion topic along with some of the other developing commercial companies. He talked about problems associated with taking government money. One of the final listener questions dealt with a big dumb booster, Mars Science Lab, and the Curiosity rover.

Dave Ketchledge, Sunday, 11-20-11 (64.45MB; download) -- Guest: Dave Ketchledge. Topics: Using nuclear power to do a humans to Mars mission. You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed back Dave Ketchledge to discuss his new book, "2033 The Nuclear Mission To Mars." The books is available in pdf format on a CD. You can order the book from this website, http://rocketengineer.bravehost.com. Later in the discussion Dave mentioned that the book can automatically download to a Nook e-reader and can be converted to be read on a Kindle. We started our 2 hour plus discussion with Dave providing us with background as to why a humans to Mars mission was important, why we need heavy lift, SLS, and why nuclear propulsion was essential. He shared reasons with us for going to Mars and talked about a Mars mission as being in our national interest. We took listener phone calls asking for a clearer explanation of why we need to go to Mars. One listener asked about the artistic side of the Mars flight, taking our focus away from technology and engineering. Terry wanted to know how many missions could be gleaned from a nuclear rocket and our guest spent considerable time going through the needed nuclear technology, providing us with a basic understanding of the technology, the risks, etc. In fact, several times during the segment, Dave reiterated why a manned Mars mission was so vital to our nation & future. In our second segment, Dave continued taking us through the various chapters in his book and talked about radiation doses for people, space travel, NASA and more. Fred, a space medicine radiation specialist, emailed in a note disagreeing with some of what Dave was saying about radiation doses. Dave said Fred was partially correct, disagreeing with some of Fred's comments. This exchange prompted Tim to call in objecting to negativity & naysayers such as Fred (in his opinion). I called Tim on this which caused me to do one of my notorious rants against la la land thinking & bad assumption making I since apologized to Tim for my outburst, but strongly oppose la la land thinking & assuming valid disagreement to be the same as being negative, including assigning emotions to commonly used terms in science, medicine, and policy discussions such as "controversial." Later in the segment, I asked Dave to explain the difference between nuclear electric and nuclear thermal propulsion. Throughout the discussion, Dave advocated for the NERVA type nuclear thermal engine. He also explained the advantages re ISP via Pebble Bed technology. As we neared the end of our discussion, Dave talked about the structure of his book, the references & data base along with the Orbiter freeware he has included with the CD. At the end of our program, I asked Dave to give us a 5 minute talk were he to be invited to testify before Congress on nuclear propulsion & a manned mission to Mars. I thought he did an excellent job in his off the top of his head 4.5 minute talk. See what you think. Post your comments/questions on blog URL above. Dave's email address is in the lower left hand corner of the above website used for ordering his book. Selected by: David Livingston [ stations ], Mon, 21 Nov 2011 17:44:57 UTC

Dr. Lucy Rogers, Franz Gayl, Friday, 11-18-11 (41.83MB; download) -- Guests: Dr. Lucy Rogers, Franz Gayl. Topic: Removing Orbital Debris. You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed back Franz Gayl and first time guest Dr. Lucy Rogers to discuss their recent Singularity University Space Team Project Final Technical Report: "Removing Orbital Debris: A Global Space Challenge." For more information about their project and the debris issue, visit their website which is www.spacedebrisresearch.com. Our guests also referenced the recent National Research Council (NRC) report on the subject, "Limiting Future Collision Risk to Spacecraft: An Assessment of NASA's Meteoroid and Orbital Debris Programs." Download the .pdf for free at http://www.nafwa.org/components/com_feedpost/feedpost.php?url=http://feeds.nap.edu/~r/nap/new/~3/0Wdaei5RGqE/catalog.php&site=Nutrition%20and%20Food%20Web%20Archive. During our first segment, our guests introduced us to their Singularity University project and the problem of space debris. They provided us with statistics for debris pollution in the most popular orbits, including polar orbits. We talked about high orbits, MEO & GEO orbits & new satellite mitigation techniques to either bring a satellite down much faster or to move it to a higher parking orbit out of the way freeing up the actual orbit for use by another satellite. We talked about those most responsible for space debris which are the U.S., Russia (former Soviet Union) & China. Responsibility for cleanup lies with these countries by treaty but as you will hear, its not always easy to know which piece of debris is the responsibility of which nation state. Later in the segment, a listener asked about the Kessler Syndrome which our guests addressed, then we talked about reentering satellites, especially from LEO. The issue of national security for satellite location/identification came up & as you will hear, this is a major issue yet to be resolved in international debris negotiations. In response to questions about why we don't have debris removal efforts with budgetary priorities, Franz talked about human nature & why it is so difficult to take action before an event actually happens. In our second segment, Dr. Rogers talked about the need to establish a trade association with all the stakeholders to work out solutions to the debris threat as it is possible that within five or so years, debris collisions could wipe out important security as well as commercial satellites. Beth asked about space tourism being at risk. Our guests said it was, specifically orbital space tourism. Another listener asked about planetary protection & the working together with groups addressing planetary protection along with debris issues. Toward the end of our discussion, an Economist online article was mentioned. You can find this article on their website in the media section http://www.spacedebrisresearch.com/Space_Debris_Research/Media.html. Scroll down until you see the Economist Online article listed from Sept. 1, 2011 www.economist.com/blogs/babbage/2011/09/innovation). The article talks about the third graduating class from the Singularity University & all their projects, including AstroTrash which was the project submitted by our guests. Other discussion topics suggested by listeners included the likelihood of a commercial company being formed to clean up space junk as well as a host of questions about international legality in space debris cleanup. Please post your comments/questions on The Space Show blog URL above. Dr. Rogers and team members can be reached at info@spacedebrisresearch.com.

Marc Millis, Paul Gistler, Tuesday, 11-15-11 (54.11MB; download) -- Guests: Marc Millis and Paul Gilster. Topics: DARPA One Hundred Year Starship Project, interstellar space travel, management of long duration projects. You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed Marc Millis and Paul Gilster to the program to discuss the recently held DARPA One Hundred Year Starship Project and the potential role of the Tau Zero Foundation solicitation proposal to DARPA for their award. For more information on the Tau Zero Foundation, visit these websites: www.centauri-dreams.org; www.centauri-dreams.org/?page_id=2118. You can also subscribe to their free newsletter from their website. In our first segment, Marc and Paul summarized the DARPA One Hundred Year Starship program. They told us about the different sections and subsections, the importance of the science fiction track and some of the non-technical tracks, and they described the Solicitation project DARPA has underway looking for a management type organization to plot the course for a century or so to bring interstellar travel to reality. Listeners had many questions for our guests but Linda asked for a reality check on the likelihood of interstellar or faster than light travel to happen within a century. Our guests said it was possible but listen to their full answer and see what you think. Later in our discussion, Marc put forth some important due diligence rules to help determine if something or someone is too far out on the fringe. This is an easy set of steps to apply so listen up and remember his guidelines. Our guests discussed the big challenge in getting space travel, especially far out interstellar travel to be relevant to most people. Another listener asked about the potential contribution of serendipity to the development of interstellar flight and then we talked about nuclear and fusion propulsion. The fusion rocket was discussed, don't miss this set of comments. Our guests were asked just how much energy was required to do interstellar flight. We were given a rule of them for baseline kinetic energy estimates and as you will hear, it is pretty basic to run the numbers. We then talked about the proportion of energy used for space now and in the future as a part of all the energy used by humanity. This presents the space users with some challenging issues. In our second segment, we talked about what could be done today and one of the favorite projects was a solar sail business plan project. Listen for details. Fusion was discussed again as was the Drake Equation as well as the Fermi Paradox in a unique combination with one another. Our discussion then focused on the search for ET, exoplanets, and more. For networking purposes, listener Ben inquired about relevant conferences and we learned that for the most part they were few and far between. Toward the end, a listener wanted to know about "low energy nuclear reaction" (LENR) and other fusion alternatives. Another listener wanted to know about finding antimatter around the Earth and being able to use it. Tau Zero has a Facebook fan page at www.facebook.com/groups/47450538997.

Gary Hudson, Monday, 11-14-11 (49.61MB; download) -- Guest: Gary Hudson. Topics: Rocket reusability and related topics. You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed Gary Hudson back to the program to discuss rocket reusability during our 1 hour 45 minute discussion. We started our discussion with an historical overview of rockets in the modern era to better enable our understanding rocket development, the role and influence of reusability. Gary started the history with Treaty of Versailles which ended WW1 and imposed strict arms controls on Germany, especially with long range artillery. This led to the German development of long range rocketry which was used in WW2 and then became the foundation for space programs without consideration to reusability. Despite this, Gary pointed to the Colliers Magazine series in 1952 in which rockets were portrayed as three stage reusable rockets. We also talked about NASA leadership and the commitment it would have to make to pursue lower cost space access and reusability. Gary then discussed reusability in the context of the recent Space X announcement on their reusability plans and went over some of the launch and fly back penalties. Don't miss this discussion. Lee emailed in multiple questions asking about the price per pound to orbit, the number of stages that might be used, rocket engine durability, hydrogen peroxide as a fuel choice, and air breathing engines. We also took a calls from listeners Trent in Australia and John in Atlanta about innovative rocket ideas and designs that could possibly be acceptable in today's space and economic climate as well as the Space X reusability plan. Don't miss Gary's comments on all of these excellent listener questions and ideas. In our second segment, Betty asked about Point to Point transportation, ramping up from suborbital, scaling back from orbital, or using hypersonics. Here, Gary had much to say, especially about the challenges for Point to Point, the obstacles involved in evolving from suborbital, and finally why he does not like hypersonics or think they will be the answer to anything. We then switched topics to the change over from the Space Act Agreement (SAA) to the FAR. Again, Gary had much to say about this but concluded that it would be disastrous. Finally, Gary told us about some rocket concept designs he works with, specifically the Hyperion vehicle. If you have comments or questions, post them on The Space Show blog URL above.

David Portree, Sunday, 11-13-11 (45.06MB; download) -- Guest: David Portree. Topics: Apollo history outreach, Native American astronomy & space education, USGS mapping, and more. You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed David Portree to the program to discuss his Beyond Apollo blog and work at the Flagstaff, AZ USGS Regional Planetary Information Facility Astrogeology Science Center. For more information about our guest and his work, visit, http://beyondapollo.blogspot.com and http://astrogeology.usgs.gov/About/People/DavidPortree. Note that Mr. Portree said the Astrogeology Science Center would have a new website effective Wednesday, Nov. 16, 2011 with new videos and lots of educational materials, as well as an Excel spreadsheet of maps and data for easy access. Our guest has suggested using Google to search for the center as the URL may change. In addition, our guest has a Beyond Apollo Facebook page, www.facebook.com/pages/Beyond-Apollo-space-history-blog/147382275296462?ref=ts&sk=wall. We started our discussion with a focus on his Beyond Apollo blog and the importance of knowing history. Among the subjects David discussed with us was his look at failure modes, specifically what might have happened if Armstrong had needed to abort the lunar landing at the last minute. He also reminded us that Apollo did not have a blank check nor did it enjoy 100% support of the population or Congress. Anthony in Pool, England asked a series of questions about time lines, fact from fiction and teaching history. This prompted my general questions to the guest about teaching history based on an agenda or ideology rather than fact. Our guest had interesting comments on this subject. As our segment ended, we moved on to astrogeology and using rovers for exploration rather than humans. A potential point of comparison was brought up regarding the Lewis and Clark Expedition and what it would have been like using rovers. In our second segment, Marshall called in about robotic exploration, the Lewis and Clark comparison, and we had email questions, all suggesting that robotic exploration enhances human exploration. Don't miss this discussion. Our next topic was that of Dark Skies and light pollution. We then moved on to space educational outreach with the Navajo and Hopi reservations. Our final two general discussion topics were the astrogeology division of the USGS and science fiction literature, especially from the UK. We talked about GPS mapping and our guest told us about the Graphic Information System technology (GIS) used by USGS in map making. Please post your comments and questions for our guest on The Space Show blog URL above. You can contact our guest through his blog/website.

Ken Murphy, Tuesday, 11-8-11 (61.63MB; download) -- Guest: Kenneth (Ken) Murphy. Topics: The Moon Society, lunar commerce, space finance. You are invited to comment, ask questions, & discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, & any discussion must be relevant & applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed Ken Murphy to discuss the Moon Society as he is now the Executive Director of the organization. We also talked about lunar commerce, space investing, & a host of other topics. We started our first segment of this two hour program talking about the LEAG conference our guest attended earlier in the day on space finance issues. Our next topic was The Moon Society (www.moonsociety.org). Ken is the new head of the organization & he shared much of his plans with us. He talked about many of the projects he wants to undertake & develop plus educational outreach efforts with NASA & others. He also spoke about lunar lava tubes & the interest in them. We discussed the commercial potential of Cis-Lunar Space development throughout our discussion. Moon interests by other national space agencies came up via a listener question & Ken expressed a concern that another nation, say China, would be able to make a claim & work it for choice lunar r/e before we are back to the Moon. We talked about the legal regime & property rights involved in commercial lunar activities. Ken introduced us to the requirement for there to be value to space projects making it worthwhile for others to pay for that value. That said, determining the value of many projects today may be challenging but this is changing. He talked about potential value creating ideas & ventures for Cis-Lunar space & even Mars. Ken was asked about the Google Lunar X Prize & he said was a game advancing program. He told us about his being at the recent SEDS event in Boulder & the consensus that the general public has abysmal knowledge about the Moon. Near the end of this segment we talked about Boy & Girl Scout interest in space & then Ken told us how he now has the Out Of The Cradle blog which is chocked full of interesting information. Visit the blog at www.outofthecradle.net. We specifically talked about the Lunar Library (www.outofthecradle.net/categories/lunar-library). In the second segment, we talked some about the space programs of the presidential candidates but Ken made a point of saying that there was no space leadership by anyone at this time. Tim in San Diego inquired about Moon-Mars competition in terms of a space program. Ken said the Moon was a sandbox for the rest of the solar system. Reda asked what motivated someone to making the Moon into a career over say Mars or something else. Listen to the excellent response offered by our guest. Next, we talked about the business perspective for potential commercial activity & inquired about mining He3 or doing a lunar based SSP program. Ken offered specific suggestions to these & other ideas so listen carefully to what he said. Toward the end of the program, we talked about Moon Day in Dallas & the Art Show that is held at the Frontier of Flight Museum at the Dallas Love Field Airport. Last year the theme was space comic books & this year it is space LP covers. Listen to Ken describe these program. I may see you there at this year's Moon Day events. Toward the end of the program, Tim in Huntsville asked about low cost space access, QuickLaunch, Falcon Heavy, rotating lunar tethers, & the O'Neill mass driver. Please post your questions & comments on The Space Show blog above. You can email Ken at lunadyne@gmail.com. Selected by: David Livingston [ stations ], Wed, 09 Nov 2011 20:36:33 UTC
