Remember, if you buy it on Amazon, use the OGLF/Space Show portal so Amazon will donate part of the purchase price to The Space Show. Instructions are on all program archives on the website, the blog, and at www.onegiantleapfoundation.org. During the first segment of our 1 hour 52 minute discussion, Erik started out with a short summary of the recently concluded Next Giant Leap space conference held in Hawaii. He concluded that it was an excellent conference with a focus on returning to the Moon and lunar missions. Next, Erik turned his attention to his new book on Bigelow Aerospace by talking about the inflatable technology being used by Bigelow modules, especially the BA 330. Erik was asked about station keeping with the BA 330 and suggested both a docking capability and propulsion mode. I asked Erik what impressed him the most and also concerned him the most. Regarding his concerns, he suggested the lunar landing capability of Bigelow, even citing Buzz Aldrin in support of his concerns. Given Erik has now written books on both SpaceX and Bigelow, a listener asked him for comparisons with the two which Erik would not do. Under pressure, he did say it might be easier to work at SpaceX than Bigelow. Throughout the show, Erik mentioned that we need advanced propulsion to go to Mars and that it was unsafe to use chemical rockets. When I challenged him on this, he held his ground citing radiation and other human factors risks as reasons why going to Mars with chemical rockets was too risky. In the second segment, we talked about the Vectran material per Tony's email. Vectran is the material used for the Bigelow expandables (inflatables). Dr. Doug from S. California called with multiple questions for Erik. He inquired about a possible Bigelow inflatable greenhouse and wanted to know if Bigelow had identified a landing location on the Moon. Doug also brought up a potential return to the Moon policy with the next president to be elected in the 2016 presidential election. Neither Erik or I thought it was likely that a new president would focus on a return to the Moon space policy. Doug commented on our comments later in the segment with an email which I read in full on air. Let us know what you think with a comment on TSS blog. Listeners asked about going to Mars rather than the Moon and Erik talked about going to the Moon as part of a Mars mission. During the program, I asked Erik what it would take to move policy makers to establishing a return to the Moon policy.

This will help me bring better programming to the audience. We welcomed our guests Dr. Dorit Donoviel & Dr. Eugene de Juan, Jr. to discuss the National Space Biomedical Research Institute (NSBRI) "Vision for Mars Challenge: A Unique Opportunity for Ophthalmology Companies." Read about this project at www.nsbri.org/newsflash/indivArticle.asp?id=454&articleID=212. For additional information on the grants, visit www.smartcap.org. I would also like to thank Kacey White for her hard work with both guests and TSS in making this program possible. During the first segment of our 97 minute discussion, Dr. Donoviel started us off with background information for the Vision for Mars Challenge, then Dr. de Juan discussed the nature of the eye problems and the effects of low gravity on the optic nerve. As you will hear from our guests, the Vision for Mars Challenge will award to small companies a grant of $100,000 to "to help identify and advance medical technologies for ocular health in space through collaboration and funding support." After this introductory part of our discussion, our guests went into detail about the medical issues relating to optic nerve changes, pressures, fluid balance and more and what this does to vision. Our guests were asked how these vision issues might impact a crew on Mars or on the way to Mars but unfortunately not much information is known at this time. Also, we do not know the needed level of gravity to offset the optic nerve, fluid and pressure changes. Our guests mentioned the upcoming year long crew visit to the ISS and that eye issues will be monitored so that accurate data on vision problems can be collected. Dr. de Juan did go into many of the medical issues contributing to the vision problem including intraocular pressure and fluid balances. In addition, we spoke about possible countermeasures. Both artificial gravity with a short arm centrifuge and mechanical intervention via a certain type of pressure garment were discussed. Medical intervention was also discussed, then BJohn suggested spinning the spaceship would be more cost effective that other types of countermeasures. Our guests disagreed, saying medical countermeasures would be designed for patients on Earth as well as astronauts so the market size of potential beneficiaries worldwide would be huge as compared to just a handful of astronauts on a spinning spaceship. Engineering problems were also cited as a severe cost driver in terms of creating artificial gravity for the crew. Marshall called to ask about Lasik surgery.

This will help me bring better programming to the audience. We welcomed back Marcia Smith back to the show for a preview of the upcoming 114th Congress & space issues with a focus on budget issues & just how congress works with NASA & space policy. During our 97 minute discussion, we started out with a short Civics 101 lesson on how Congress works, NASA funding, & Congressional oversight of NASA. For those of you not that familiar with how the U.S. Congress works and funds space programs with NASA, you will find this short discussion most helpful. Marcia explained both Senate and House roles and their appropriations and authorization committees. As you will hear, Congress controls NASA spending and there is very little discretionary spending available to the NASA Administrator. As for the new Congress that will be taking office in early January, the big focus will be on budget issues because by law, the sequestration returns for Fiscal Year 16. If Congress keeps the sequestration in place, while hurtful to many government agencies and programs, it is damaging to NASA. We also talked about a possible renewed interest in the Europa Mission as Texas Representative John Culberson will chair the House Appropriations Subcommittee for Commerce, Justice, and Science. His Houston district is close to JSC & he's very enthusiastic about NASA and a Europa mission. Marcia mentioned the NASA SOFIA program as an example of Congress wanting the program despite it being eliminated in the budget proposal so it added it back in to the NASA budget. Listeners asked about long term projects being funded for longer than a year. Marcia addressed this issue though there is no good answer because Congress has oversight & they can change or modify positions from year to year. Our guest was asked about Congressional policy impact on the private & entrepreneurial space industry. Unless a public/private partnership exists or the government is a major customer of the private company, congressional policy does not overlap into the private sector. It is also important to distinguish between regulatory and budget issues as we are talking budget issues in this program. Several listeners wanted to know if the media and the public could impact Congress & space policy makers. Another set of listener & Space Show comments over recent weeks addressed the 2016 presidential election, wanting to know if history bears out a change in president equaling a big change in space policy. Don't miss this discussion. Later, Ralph in Phoenix wanted to know if the Falcon Heavy was very successful, would such a success impact congress & policy makers to move away from the SLS program as unnecessary.

John Batchelor and I welcomed Dr. David Grinspoon (http://funkyscience.net) to Hotel Mars to discuss Comet 67P, the Philae lander, and what has been learned so far from the science instruments aboard Philae and the orbiting Rosetta spacecraft. We discussed the likelihood of Philae waking up and working again as the comet gets closer to the sun, the unfortunate landing of Philae and its bounces, plus the discovery of organics for the comet. We also talked about the chances of finding amino acids & specific proteins once the data is evaluated. I asked how high Philae bounced on the landing and how close it came to escape velocity given the low gravity on 67P and the very light mass of Philae equal to about a paperclip or piece of paper. We also talked about the comet ice and if the ice would melt or survive were a comet like this to enter the earth's atmosphere. Please post your comments/questions on TSS blog. You can email Mr. Batchelor or Dr. Grinspoon through me.

This will help me bring better programming to the audience. We welcomed Jim Muncy back to the show to discuss the recent Virgin Galactic accident, Antares, commercial space, regulations & more. During the first segment of our 100 minute program, Jim started off by discussing the Virgin Galactic accident and possible new regulations for the industry or vehicle specific to Virgin. Jim explained the Commercial Space Launch Amendments Act of 2004 in terms of the regulatory regime which already exists and what might come about once the NTSB issues its final accident report. This is an excellent discussion as well as clarification of the existing and potential regulatory environment so don't miss it. Space attorney Michael Listner emailed & called in to support what Jim was talking about regarding regulatory regime for commercial space with the AST. Doug Messier sent in an email addressing the issue of there being a difference between having an incentive to fly safely and being able to operate safely with regards to Virgin as our conversation had turned to flight safety for the new spaceplanes. Regarding flight safety, Jim made the point that safety was ongoing and a continued learning lesson, even after the vehicle was in commercial service. I agreed & pointed to commercial aviation accidents that have happened after thousands of flight hours as some defect shows up that late into commercial operations. Jim seized the opportunity to talk about the choice of wording regarding space tourism and said it was not a good choice of words. Listen to what he had to say about this. We talked about negative press after the accident and here Jim stressed that the spaceflight in question was not taxpayer supported and was between private individuals and companies. It was not the business of journalists or others. Cost plus contracting came up with a listener question as did several established Republican senators and the role they might play regarding commercial space in the new congress. Jim had made several earlier comments about the British press negative articles on Virgin and the industry. I asked him why that was so and said it was largely Richard Branson driven given he is and has been such a controversial person in the UK. In the second segment, we talked about some emerging commercial lunar opportunities that Jim has worked on for awhile. He provided the background to the current situation including fights over SLS, Orion, & other big ticket NASA programs. This is a very interesting discussion because it shows how one can find areas to agree on and work together and even get funded if the amounts are not too large. I urge you to pay close attention to this part of our discussion. Read the rest of this summary @ www.thespaceshow.com or http://thespaceshow.wordpress.com.

This will help me bring better programming to the audience. We welcomed Rick Boozer and John Hunt to the program for our special WEBINAR SLS Debate. You can hear the audio only for this debate as you would any Space Show program. The video can be found on our Vimeo Space Show Channel, http://vimeo.com/channels/thespaceshow. Note that the mic lock on my microphone did not work which is why the mic kept swing back to in front of me during the show. Also, I looked down as I was writing notes for the show summary. Both of these issues will be corrected for the next webinar. Rick's book on the subject, "The Plundering of NASA: An Expose" is available on Amazon. If you purchase the book and I hope you do, please use the OGLF/Space Show Amazon portal so Amazon will make a contribution to TSS. Instructions are on the website, the blog, and all program archive summaries. During the first segment of our two hour webinar, both John and Rick made five minute opening statements followed by a 2.5 minute rebuttal of the position statement by the other guest. Rick Boozer does not support SLS and John Hunt does support it. John went first, putting forth a good summary of why he supports SLS, the benefits it provides, and the importance of the project. Rick's opening statement outlined why he opposes the SLS rocket, calling it an "existential threat." He also said SLS was a "rocket to nowhere." The opening statements provided the basic positions for both guests as they debated all aspects of SLS so do carefully listen to their respective position comments. We took both calls and emails from listeners. Evon emailed in wanting to know what the money saved from SLS would best be spent on. John pointed out that there was no assurance that any savings would even be spent on space let alone his priorities. While Rick agreed, he did list several projects he felt far more deserving of funding, including using the funds to speed up the commercial crew program since it has never been funded to the level requested by the President. Rick took the opportunity to bring up cost plus contracting and why it was not suitable for a more mature manufacturing project, instead being best suited for R&D projects. He said that was a driver in the high cost of SLS. In contrast, John cited his aviation experience with the A12 and P7 aircraft using fixed price contracts, cancellations, and more. Dr. Doug sent in a note asking about the fundamental need for a heavy lift rocket. Our guests had a different take on Doug's question so listen to how they answered it. Rick pointed out the advantages of the SpaceX Falcon Heavy as compared to the initial SLS version. You can read the balance of this summary @ www.thespaceshow.com/http://thespaceshow.wordpress.com.

This will help me bring better programming to the audience. We welcomed Rand Simberg back to the show for a wide ranging discussion on top space news items, the SS2 accident update, space policy issues, and more. During the first segment of this 96 minute program, Rand led off with the mentioning of the 45th anniversary of the Apollo 12 launch. Next up was a short discussion about Comet 67P and the Philae lander, then Rand mentioned his current article in PJ Media, http://pjmedia.com/blog/commercial-spaceflights-terrible-horrible-no-good-very-bad-last-week-of-october. Rand talked about what is currently known about the SS2 accident, the NTSB investigation, & that nothing has been ruled out as a cause or partial cause for the accident. When asked if he thought the accident would cause the FAA to start regulating the industry, he did not think so but listen to his reply. This topic also came up in the last segment of our show. Rand mentioned that XCOR was moving ahead & there technology is different from the one employed by Virgin. He also made a point of explaining multiple times that a test flight was not a commercial flight. Rand got some listener emails about investment in Virgin and if it was waning. Helen emailed in asking about a possible lapse in the Virgin safety culture. Carl emailed in about the impact of the SS2 accident on Spaceport America. We switched gears and talked about Antares, the Orbital-ATK merger, & the use of Russian rocket motors. In the second segment, Rand was asked about the possible impact on Virgin's customer base. Rand said that the bigger risk was the investment risk. The RD180 came up again as did the Atlas 5, Delta 4, and the Falcon 9. We talked about possible midterm election impact and here Rand thought there might be more impact on the DOD side than NASA. We discussed projects that might be cancelled as a result of the election and the ARM topped the list. he did talk SLS and thought that eventually it would be shut down, especially if SpaceX gets Falcon Heavy flying. Rand also mentioned the NRC Pathways Human Spaceflight Study but was critical of it, especially the part that said there had been no and will be no launch vehicle advances for the past 30 years. Dr. Lurio was our first caller & he wanted to discuss possible FAA regulations, his understanding of the test flight vs. commercial flight policy application & more. They talked about hybrid rocket motor vibrations and the unknowns regarding the current test flight. Toward the end of their discussion they joked about using SLS to launch many many cubesats. Kirk emailed us with a question about methane engine. Read the rest of this summary @ www.thespaceshow.com or http://thespaceshow.wordpress.com.

This will help me bring better programming to the audience. We welcomed Bob Zimmerman back to the show to discuss a variety of space news items and events. During the first segment of our 2 hour 2 minute show, Bob opened up talking about Comet 67P, the Rosetta mission, and the Philae lander which will land on the comet on Nov. 12, 2014. Bob spent some time describing 67P, the lander, the landing site, and the topography of the landing zone. Next, I asked Bob about the recent court decisions in Italy regarding the appeals court decision on the seven scientists accused of incorrectly predicting an earthquake that led to lots of damage and death. Bob clarified the issues for us and the decision of the appeals court. We talked some about the possible impact on space policy for the recently held mid-term elections. Bob was asked by a listener if he thought the election result would lead to the cancellation of SLS as well as the NASA ARM project. See if you are surprised by Bob's analysis. Ken in San Diego asked Bob about negative press articles regarding stopping space tourism in light of the SpaceShipTwo accident. The USA Today editorial of today was cited as an example. Bob did not think these articles would have any serious or long lasting impact and had much to say about the authors and publications writing them. Before our break, Rob in Denver emailed in about Comet Siding Spring changing the Martian atmosphere when it swung by Mars. In the second segment, Jeff emailed in about comments that Virgin has said it would be flying by April. Bob was very skeptical about that timeline. He had much to say about the investment and more regarding Virgin. Bob then spoke about the upcoming Orion test flight set for Dec. 4 and heat shield issues. Our guest spent some time dwelling on the heat shield issues which he said helped make his case that SLS/Orion were not sustainable projects. Ben called from Orange County to talk with Bob about the Bigelow module going to the ISS in 2016, then they talked a bit about solar sales. Ed emailed Bob to see if he knew what alternative launcher Orbital might choose given the Antares problems. Bob spoke about the upcoming Russian rocket test for the new Angara 5 rocket. SLS John called in about earlier comments Bob made regarding the Saturn 5, then they talked about SLS. Please post questions and comments on TSS blog above.

For more information, visit his websites, www.andyweirauthor.com and http://www.galactanet.com. During the first segment of our 100 minute show, Andy started out by telling us how he came up with the story idea, & his three years spent in writing the book. I asked if he used consultants, NASA, or other aerospace experts. He said no & that most of the feedback and help came through suggestions from people who read the chapters he put up on his website. Andy also did his own research, math work, physics, and engineering analysis. He talked about a few errors that were pointed out to him & indicated that the most challenging work were the times and orbits regarding Mars and the missions described in the book. During the show, Andy got lots of email questions and phone calls regarding certain story lines and sections of the book. He was also asked about life on Mars but that issue was not relevant to his story. He did get questions about the human waste recycling carried out on Mars & why he chose Mars and not the Moon or another destination. Sandra asked him about the private space company plans to visit and/or settle Mars given how hard it was for Andy's character, Watney, to survive. Andy had very interesting comments on this question including the Elon Musk Mars plans and then Mars One. Human factors were brought up including radiation, microgravity, vision problems, and more. Andy did address these issues in the book so listen to his reply to this line of questioning. As the segment ended, we talked about using Phobos and Deneb for Martian navigation along with Watney's trek to get to Pathfinder to use its parts for communication. NASA came up several times in the segment as readers get a pretty good "view" of NASA problem solving, information, data, and PR control, plus amazing creativity. In the second segment, we had lots of listener emails and phone calls. Andy was asked what science fiction had influenced him, then he got an interesting email from Andrew in Tucson who had actually worked on the Pathfinder hardware. Andrew said Andy was spot on accurate! Dr. Doug called on many topics including using the Hohmann Transfer Orbit which Andy did not use as he designed Hermes, the big spaceship, to work with constant acceleration using ion propulsion. The Aldrin Cycler was also mentioned. Listeners mentioned the new movie Interstellar and made some comparisons if they had read "The Martian" and seen the move.
