Contact Dr. Livingston for questions about our copyright and trademark policies which we do enforce. For this Classroom Space Show two hour program, we welcomed Dr. Paul Spudis and Dr. Jim Vedda for a comprehensive discussion on the importance of undertaking Cislunar space development as a major focus of U.S. space policy. Our program was in two equal segments but since our topics crossed segments, our summary will reflect the entire program, not each segment. Also, at the end of this summary, I have listed several relevant URLs for cislunar space development and our guests. If you want more information on the subject, I suggest you visit the recommended websites and blogs. Our guests described cislunar space for us and did an excellent job in letting us know why it is important to focus on a cislunar space development program. In the process of addressing this very important issue, we talked about policy, the railroad model, the need for space infrastructure, insitu resource development and understanding, lunar water, lunar ice, lunar polar robotic exploration, the need to learn to live and behave in space, and much more. Listeners called and asked email questions that drew out both our panel members so that our discussion was sufficiently thorough. Side issues were discussed such as budget cuts, tight budgets, how to do cislunar space in a belt tightening environment, small businesses and contractors, even sequestration. Our guests were very clear as to why cislunar development was much more preferable than "space stunt accomplishment" types of programs and projects. Our guests presented a good case in letting us know why cislunar development is preferable over a humans to Mars mission at this time. Another issue brought up by a listener was to ask about "Plan B" if for some reason there was no water or there was insufficient water/ice on the Moon. Dr. Spudis explained why that was not likely but both panel members talked about why cislunar development was important to even without sufficient water/ice resources on the Moon. Here are the URLs of interest I mentioned above: First, Dr. Vedda's new book, "Becoming Spacefarers: Rescuing America's Space Program" is at www.amazon.com/Becoming-Spacefarers-James-A-Vedda/dp/1477130918/ref=onegiantlea20.

Space Show programs can be quoted in news articles, papers, academic & research work but must be cited or referenced in the proper citation format. Contact Dr. Livingston for questions about our copyright & trademark policies which we do enforce. Welcome to our fist Space Show audition program. Most callers talked about their projects to earn a place as guest on the program. We received email questions from listeners for the caller. Tell us on the blog if you would like to hear a specific caller as a guest on The Space Show. John was our first caller regarding his concept for a Two-Stage-Tether-to-Orbit program. I'll upload his two PDF documents to the blog, both of which explain in detail what he summarized on air. Doug was next to talk about Cislunar development around lunar ice at the poles, a moderate heavy lift such as the Falcon Heavy, propellant transfer and depots, and depot locations along with cargo transportation. Doug was asked about markets for his concept which he said might include satellite servicing. When asked about his time line in a "perfect world" supporting his concept, he suggested about 11-12 years. He also talked about a lunar settlement and his Lunar Cots Petition (www.ipetitions.com/petition/lcots). Andrew in Tucson was the next caller, encouraging people with ideas to assemble a garage type tool shop to learn to make simple parts of the hardware supporting their ideas. He talked about tools going back to WW2 & the '60s as being valuable & important today. He explained why he was encouraging people to learn to do at least the basics of building their project components which would help obtain financing & spur the interest of others. He will soon have some of his videos on YouTube so search under his name for more on his idea, "Andrew Tubbiolo." Jeff from Tucson called next to talk about taking a holistic view of space programs/projects such as SLS. He talked extensively about the need for solid rocket propellant per SLS & made the case for NASA being an integral part in our national security via its use of solids, space projects, etc. He stressed the holistic broader view over a more narrow view brought up by listener emails such as cost, economics, etc. Our much shorter second segment started with a call from Armen who talked about the interstellar roadmap which could change the way space projects are financed. He talked about financing being the bottleneck for space projects, then explained how the Fed creates money, debt/credit relationships, and how something like QE3 could be replaced by putting the $40 billion in one month toward space companies per the roadmap. The roadmap by Star Voyager was discussed. You can obtain more information from the Leeward Space Foundation (www.leewardspacefoundation.org). For specifics, www.leewardspacefoundation.org/id32.html. Our caller then talked about the International Space Development Hub (ISDH) at www.isdhub.com. ISDHub has proposed NASA Ames transform Hangar One at Moffett Field from a parking space to a space business hub. For details, see www.isdhub.com/about-us. Place your comments/questions on our blog. Let us know who you would like to hear as a guest on The Space Show. You can email the callers through me. Selected by: David Livingston [ stations ], Wed, 17 Oct 2012 17:41:28 UTC

Wayne White, Monday, 10-15-12 (63.90MB; download) -- Guest: Wayne White. Topics: Space law, The Space Pioneer Act, property rights & commercial space development. 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 Wayne White back to the program to discuss his proposal for The Space Pioneer Act (SPA). His Power Point presentation on this Act has been uploaded to The Space Show blog. Later in the program we talked about his new business venture, SpaceBooster, LLC. Background on SpaceBooster has also been uploaded to The Space Show blog. Mr. White started our discussion with an overview on his proposed SPA and the five United Nations treaties that generally control the behavior in space by all nations, including the issues of property rights, space salvage, and space mining. Mr. White spent a considerable amount of time on this discussion, the Outer Space Treaty (OST) and the Moon Treaty. Our guest then introduced us to the idea of "innovative financing" which is a type of tax being proposed in the U.N. This prompted quite the discussion. Next, our guest took us to salvage law, the Law of the Sea Treaty, and the space asset registration lists with both the Air Force and the U.N. Transferring ownership title of space based assets was a major part of this part of the discussion, including reciprocity with similar laws that might eventually be enacted in other countries. Atty. Michael called in and we had a mini-legal debate on these issues, the treaties, enforcement, and alternatives. Wayne then introduced us to the Deep Sea Hard Mineral Resources Act as being relevant to parts of The Space Pioneers Act. In our second segment, Wayne talked about the history of many of our laws consistent with what he proposes in his Act. He said that 2012 was the 150th anniversary of the Homestead Act and he connected the benefits of the Homestead Act with what might happen in space with the SPA. He also talked about the 1872 General Mining Act which then led him to talking about Article 2 of the OST. Our guest was calling for the "use it or lose it" regime. Space mining was discussed in this segment along with jurisdictional issues, both internationally and domestically. Later in the segment, Wayne talked about his new business, SpaceBooster LLC. You can find out more by visiting their website, www.spacebooster.com though Wayne did say the website is still under construction and being developed. Near the end of the program, we talked about space tourism liability, informed consent, insurance, and the meaning of the term "spaceflight participant" as opposed to being a passenger. Please post your comments/questions on The Space Show blog. You can reach Wayne White, Atty, through The Space Pioneer Act presentation on our blog.

Dr. Stephen Fuller, Sunday, 10-14-12 (59.36MB; download) -- Guest: Dr. Stephen Fuller. Topics: Sequestration and its potential impact on DOD Agencies, aerospace, NASA & non-DOD agencies. 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 Dr. Stephen Fuller to the program to discuss the potential impact of the Budget Control Act of 2011 (sequestration) on DOD and the aerospace industry. You can read and download his report at www.aia-aerospace.org/assets/Fuller_II_Final_Report.pdf. We started our discussion with Dr. Fuller providing us with the background and history leading up to the adoption of the sequestration law in 2011 and what it means across a broad group of stakeholders as well as all of us since no one will escape its impact and consequences. Dr. Fuller provided sequestration specifics, especially for 2013, plus the added impact of the law when the multiplier effect is added in to the analysis. We discussed different perspectives on sequestration, including the one suggesting that this might be the best thing possible for the country because it will finally impose strict fiscal discipline on the spending. We contrasted the "cold turkey" approach with a more targeted and disciplined approach designed to accomplish the same trillion dollar reduction over ten years. We talked about the sequestration impact in DOD and aerospace, plus Dr. Fuller told us about his research on its impact with NASA. Listeners wanted to speculate how NASA cuts might impact commercial crew, SLS, the planetary programs, and James Webb. During this segment, our guest did an excellent job of explaining the likely collateral damage throughout the economy should sequestration happen. Dr. Fuller also talked about the effects of delaying the onset of sequestration to February or March 2013. Here, the workforce cuts are more severe as they have to reach a certain goal in FY 2013 but will have less time to reach that goal. Near the end of this segment, Dr. Fuller explained the impact on primary contractors as well as the subs and small businesses. As the segment ended, Doug ask about specific NASA programs. Listen to what Dr. Fuller said about specific NASA cuts impacting NASA centers. Finally, he talked about the damage done to the economy by economic uncertainty caused by sequestration and the concern that Congress will not reach a compromise to fix the problem. In the second segment, John called in to say that after the election, he thinks Congress will reach a settlement and sequestration will not happen. Dr. Fuller used this segment to go into more detail about sequestration consequences with the different economic sectors. He talked about current procurement orders compared to future procurement orders and what sequestration does to research and development. I asked Dr. Fuller about his having testified before Congress about his study & he shared his experiences with us. He also talked about possible less severe ways of dealing with sequestration if it comes to pass, including rolling job furloughs rather than layoffs. Near the end of our discussion, I asked about the sequestration impact on capital acquisition in the private sector & Jack from VA called in to talk about R&D, especially with DOD. In closing, if sequestration is of concern to you, let your congressional delegation know your thoughts to encourage them to reach some sort of compromise to avoid sequestration. If you have comments/questions, please post them on The Space Show blog. You can email Dr. Fuller through me. Selected by: David Livingston [ stations ], Mon, 15 Oct 2012 16:46:21 UTC

Our program started with an opening statement about the Center by each of our three guests. As you will hear, John and Nick were students at the Center while Chuck has been a user of services provided by the Center as well as providing internship opportunities for the space law students. Each guest told just how important the Center was and still is to them and their work. Throughout our program, we talked about the Center Director, Joanne Irene Gabrynowicz who has been a guest on this program several times in the past. In our first segment, we talked about international space law, U.S. space law, and other space law schools, comparing their programs to those offered by the National Center. Specific issues such as remote sensing were highlighted as was commercial space, and telecommunications. Published by the National Center, the Journal of Space Law was discussed, including the archival base as well as new issue subscriptions. We talked about some of the articles published in it and the publication as an outstanding resource for space law and researchers in general. Also mentioned was the Res Communis blog which is a free subscription providing important and timely information about aviation and space law issues. Michael called in to talk about academics, treaty space law, international space law issues, and the contributions to the field from the Center. He mentioned the upcoming 7th Galloway Symposium on Critical Issues in Space Law in Washington, DC, an event sponsored by the Center. You can find out more about this event on the Center's website. In our short second segment, I asked about planetary protection and Article 9 of the OST based on our program earlier in the week with the director of NASA's Planetary Protection office. Our guests told us about their studies and work in this area and the relevance of this to the work of the Center. Listener Sagi called in to talk about the Center and how it has benefitted him in his law practice & more. I also thanked him for his part in helping me set up this program with our three guests. Other topics during this segment included commercial space, commercial space companies, other space law programs in the U.S. and around the world, plus the European Code of Conduct for Outer Space Development. Our three guests left us with meaningful closing comments which you definitely want to hear. Please post your comments/questions about this discussion on The Space Show blog.

Dr. Jason Cassibry, Tuesday, 10-9-12 (53.93MB; download) -- Guest: Dr. Jason Cassibry. Topics: A technical description and the potential of fusion propulsion. 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 Dr. Jason Cassibry to the program to guide us in our discussion of the potential for fusion propulsion. At times, this was a very technical discussion. To assist in following it, I have uploaded to the blog his published paper delivered at the AIAA Joint Propulsion Conference, "The Case and Development Path for Fusion Propulsion." In addition, below are the URLs for several articles on fusion propulsion that Dr. Cassibry shared with us:
www.uah.edu/news/items/10-research/2501-slapshot-to-deep-space#.UDrKn-iPVuY;
www.popularmechanics.com/science/space/rockets/the-big-machine-that-could-lead-to-fusion-powered-spaceships-9450996; http://io9.com/5921673/nuclear-slapshots-could-propel-a-spacecraft-to-mars-in-just-weeks; www.centauri-dreams.org/?p=23442 and http://nextbigfuture.com/2012/10/zpinch-nuclear-fusion-pulse-space.html. Dr. Cassibry started out by providing us with a working definition of fusion propulsion. We talked about nuclear propulsion as well and the overall state of development for fusion energy. I asked Dr. Cassibry if in their economic projections for fusion propulsion, they considered the political and policy impact on fossil fuel pricing and supply availability. As you will hear, generally such factors are not included in their studies though he concurred with me that such policies can strongly skew the economics one way or the other. Several calls came in on a wide ranging group of associated topics. We talked about the main fusion fuel, lithium deuteride, magnetic nozzles, and the use of a nuclear fission reactor to start the fusion propulsion unit. Z-Pinch technologies were defined and discussed. As the segment drew to a close, I asked about funding sources for this research and we learned that most all of the funding is from public sources. In our second segment, more listeners called in regarding insitu resource usage, nuclear propulsion to start the fusion unit, and the power consumed for all of this. We talked about using fusion propulsion for a Mars mission and what it did for travel times. Jason also put forth a suggested time line and path to follow to operation in perhaps 25 years, depending on funding. More calls came in with fuel questions, vibration impact, G force acceleration, thrust, and more. Another topic discussed was fusion propulsion for the launch vehicle. We then compared some real mission travel times such as Cassini, Voyager, and New Horizons, asking what the transit times would have been like using fusion propulsion. As we were ending the program, I asked about the students entering aerospace engineering at UAH, both the undergrad and graduate level, plus the gender mix of the students. There appears to be strong demand by the students to study these fields at all levels. In conclusion, Jason suggested that we could look for breakeven with fusion in about ten years, maybe less. If you have comments/questions, please post them on The Space Show blog. Dr. Cassibry's faculty page at UAH is www.mae.uah.edu/faculty/cassibry.shtml.

Dr. Catharine Conley, Monday, 10-8-12 (44.26MB; download) -- Guest: Dr. Catharine Conley. Topics: NASA & international planetary protection policy, methodology, & applications. 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 Dr. Catharine Conley, NASA's Planetary Protection Officer to the show for a comprehensive discussion on the subject of planetary protection. Planetary Protection is concerned with preventing the transfer of life between planetary bodies. For more information, visit the NASA Planetary Protection website at http://planetaryprotection.nasa.gov. Dr. Conley started our discussion with the definition of planetary protection, followed by a brief history dating back to the Apollo missions & planetary quarantine. Dr. Conley talked extensively about microbes & their survival. One of the points she made in response to a question was just how friendly the very cold temperatures of space could be for microbes. On the other hand, radiation & the UV light are the enemies of microbial survival. We talked about a Mars sample return mission, what safety precautions would be taken, & then our guest was asked about using the ISS or the Moon as a quarantine lab to protect Earth. You will hear why this is not a good idea & later when asked about using a Bigelow habitat as a planetary protection lab since it would not be a government lab, our guest applied the same reasoning. Dr. Conley talked about the Viking missions as the most stringent ever for planetary protection. In terms of the methodology, we talked about how a mission is prepared for planetary protection, the probability of contamination, & I asked about cost-benefit analysis & the value of added costs & more time for planetary protection if the probability of contamination was so low. As you will hear, building in planetary protection starting with the concept stage is not a significant contributor to costs as its usually less than 1% of mission costs. We also talked about protocols for a NEO mission, the New Horizons mission on the way to Pluto, & missions to other planets & flyby missions. Next, our guest addressed issues with Mars Science Lab & Curiosity. Near the end of the first segment, we talked about international protocols, Article 9 of the OST, & the international COSPAR Planetary Protection Policy. Dr. Conley talked about international space agency adherence to the policy, country by country. Viruses & extra-terrestrial life possibilities brought us to the close of this segment. In our second segment, Dr. Conley talked about the need for public awareness & educational outreach regarding planetary protection. Listeners asked about human flights to Mars, even one way flights. Don't miss this discussion. Did you know that it is very likely that humans will be restricted as to where they can go on Mars based on planetary protection policy? Or, by the time we send humans to Mars, we will have learned enough about Mars so that the human part regarding planetary protection will not prove to be much of a threat or risk. We talked about terreforming, what to do with a crew member death on Mars & being able to bury the body, then we talked about planetary protection policy among the NASA centers. Near the end, our guest was asked about the Phobos-Grunt mission & the Russian adherence to planetary protection policies. We inquired about Mars meteorites here on Earth & future missions being worked on with the planetary protection office including two Mars missions & the concept of a Europa mission. Please post your comments/questions on The Space Show blog. If you want to contact Dr. Conley, send your note to me & I will forward it to her.

Open Lines, Sunday, 10-7-12 (69.52MB; download) -- Guest: Dr. David Livingston. Topics: Open Lines discussion on various space topics per the choice of the listeners calling today's show. 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. Welcome to today's two hour 15 minute Open Lines discussion. The program was in three segments but as we focused on just a few topics for the entire discussion, this summary will not be divided by segments. I started the discussion by describing upcoming Space Show programs, then putting out a few discussion topics. As it turned out, the dominant topic discussed by the listeners had to do with astronaut safety and the recent program with guest Rand Simberg from Monday, Oct. 1, 2012. Rand talked about our being too risk averse, the need for more lives to be at risk to do valuable space missions, etc. You can hear his program at http://archived.thespaceshow.com/shows/1863-BWB-2012-10-01.mp3. Several callers took issue with much of what Rand said and for the most part thought that space missions were valued and that human spaceflight was already risky. Listeners went back and forth on this topic across all segments of the program, talking about shuttle accident rates, proposed accident rates for Constellation, Orion, Dragon, and more. Some listeners even talked about aviation safety rates, military jets, and the track records of the Atlas 5, Delta IV, and Arianne V rockets. For part of this discussion, we also talked about the liability limitation laws passed in spaceport states including California which recently signed into law its version of law. We talked about what this might mean for the industry, for spaceflight participants, and even if the would hold up in an accident.
As part of the HSF safety discussions, we also talked about launch abort and escape systems. We took a call at the first of the second segment from Charles in Oregon who wanted to talk about the lunar space elevator, SLS and propellant depots, our second most talked about topic for the day. Charles is a strong proponent of the lunar space elevator and depots, but others called in from the skeptical side of things which was my position. At times the discussion switched to the space elevator here on Earth but everybody agreed that the lunar space elevator was much more doable. I kept challenging Charles and proponents of this and the depots to show me the complete and thorough financial analysis and trades for these missions with assumptions as that would be the only way to know if these concepts had legs to stand on. If Charles does get me some of this documentation and its viable, I will use it in a future Space Show program. Tim in Huntsville wanted to know my thoughts on various alternative launch systems & my preferences for which type of space missions. There were other topics scattered throughout our program including the 23 mile skydive by Felix Baumgartner with Red Bull scheduled for Oct. 8th, fusion propulsion, and the SpaceX launch going to the ISS later today. If you want to email any of the callers to this program, send your note to me and I will forward it for you. Please post your comments/questions on The Space Show blog URL above.
