The John Batchelor Show "Hotel Mars," Wednesday, 3-28-12 (10.63MB; download) -- Guests: John Batchelor, Dr. Darren McKnight, Dr. David Livingston. Topics: The ISS and space debris avoidance, space debris mitigation. 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. This program is archived on The Space Show website, podcasting, and blog sites with permission from John Batchelor. Please visit the John Batchelor Show website for more information about this fine program, www.johnbatchelorshow.com. The topics in this 20 minute plus segment focused on recent news reports regarding the risk to the ISS by incoming space junk. The six crew members got into their Soyuz lifeboats, sealed the hatch and in the worst case scenario of a hit and damage to the ISS, they were ready for an emergency return to Earth. You can read about this incident from many sources on the web or you can check out the story here: www.guardian.co.uk/science/2009/mar/13/space-junk-nasa. Mr. Batchelor started out by asking Dr. McKnight if NASA had Plan B ready given the high number of debris objects in space. Dr. McKnight talked about the debris that is cataloged and not cataloged, and the risk factor the ISS astronauts accept by going to the space station. Darren then spent a few minutes talking with us on how solar cycles impact the quantity of space debris in the lower orbits. We also talked about liability issues should debris do damage. In the latter part of our discussion, John asked Darren about remedies. We talked about them for both the LEO orbits and the higher GEO orbits. Tumbling Russian rocket bodies were mentioned and I asked how the tumbling is stopped so the rocket body can be mitigated as a piece of debris. Our discussion ended when John asked Darren if there were space debris cops to enforce debris mitigation efforts on launching companies and countries. Post your comments/questions on The Space Show blog URL above. If you want to email either John Batchelor or Dr. McKnight, please send your note to me and I will forward it.

Dr. John Jurist, Tuesday, 3-27-12 (73.46MB; download) -- Guest: Dr. John Jurist. Topics: This is the first in a series of programs focused on the use of bisphosphonates to mitigate bone loss in long duration spaceflight. 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 back Dr. John Jurist for the first of several programs devoted to understanding bone loss in microgravity & the use of prescription the bisphosphonate family of drugs to mitigate the problem. Dr. Jurist provided talking points which you can find below this summary on The Space Show blog. A significant portion of the second segment is devoted to understanding these talking points so follow along. We started our discussion with an explanation of the bone loss problem facing those in microgravity. Following this brief overview, Dr. Jurist told us about bisphosphonates, the origins of this drug, how it was developed, how its usage, what some of the side effects are, some of the trials that have been associated with the drug, & space/NASA studies. Later in this nearly hour long segment, we talked about the human population & what happens to our bone mass at various stages in our life. We talked about gender, racial, & ethnic differences in human bone mass issues. As you will hear, there are gender & other differences among our diverse population. This led us to asking about using targeted genetics in selecting crews for longer spaceflight missions. Genetic modification was mentioned, especially for the long term, but for the near term, looking for better exercise routines & pharmaceutical modification/treatment seem to hold the most promise. Dr. Jurist then talked about bisphosphonate side effects. Fast transit time to Mars or a long duration mission destination came up. As you will hear, even if you get to Mars faster, you still have the problem on the surface of Mars. The big problem is we have no credible information on what the gravity prescription for humans needs to be so we do not know if Martian gravity is sufficient to mitigate the problem. Next, we focused on the need for an orbiting centrifuge, we talked about the size & spin rate of the centrifuge, & what to actually test for in experiments. Dr. Jurist suggested that starting with 1/6th lunar gravity made sense because if it was sufficient, we would know that anything stronger than 1/6th would work. If not, we should probably next experiment with Martian gravity which is about 1/3rd Earth gravity. In our second segment, Dr. Jurist referred to his talking points which you will find on The Space Show blog. We went line by line so follow along with us. Despite interruptions, John stayed on topic with the talking points. Listener questions asked about how gravity & having a load on bones works & what happens in space when that load is no longer present. We talked about the time prescription as well as the load factor (G force). Toward the end, John told us about a reviewed radiation article from 2010 showing that radiation impacted bone loss so the issue in space is more complex than just microgravity. Near the end, John got a question asking about ETs & their thin, pencil like shape making them perfectly designed for microgravity. This was both an interesting & fun discussion, bordering on science fiction. Another question asked about fish, reptilian, sea mammal, & bird bones. Our final topic dealt with the release of personal astronaut medical information & others & the ways for private information to be legally released to the public. Please post your comments/questions on The Space Show blog URL above. Email for Dr. Jurist can be sent to me for forwarding. Selected by: David Livingston [ stations ], Wed, 28 Mar 2012 17:17:13 UTC

Dr. Pal Brekke, Monday, 3-26-12 (44.06MB; download) -- Guest: Dr. Pal Brekke. Topics: Solar physics, astronomy, and his new book, "Our Explosive Sun." 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. Peter Brekke to the program to discuss his new book, "Our Explosive Sun: A Visual Feast of our Source of Light and Life." The book is available on Amazon & if you use this link for your purchase, Amazon will donate to The Space Show/OGLF: www.amazon.com/Our-Explosive-Sun-Visual-Source/dp/146140570X/ref=onegiantlea20. Additional information you will hear discussed during this interview can be found at the following websites: www.norway.org/News_and_events/Research--Technology/Pal-Brekke-at-the-Smithsonian-/; www.solarmax.no/Aurora/Home.html; http://www.springer.com/astronomy/extraterrestrial+physics,+space+sciences/book/978-1-4614-0570-2. Dr. Brekke began our discussion with an overview of his new book, how he structured the book, & its appeal to readers of all ages. We talked about how our knowledge of the sun has increased in recent years, especially since the SOHO satellite in 1995. He told us that his book is arranged as a visual tour. We also discussed the sun & cultural differences around the world. Listener Sandy wanted to know about solar storms, solar flares, & CMEs. This led to a question about the relationship of the sun to climate change on Earth. Don't miss this part of our discussion. Dr. Brekke introduced us to the subjects of auroras & space weather. As the segment ended, a listener asked about the physical location of solar satellites. How close can they be to the sun? As you will hear, most of the solar satellites are orbiting Earth, but SOHO is the one that is the greatest distance from Earth, parked at 1% of the distance to the sun so it can observe the sun 24 hours day. In the second segment, Dr. Brekke talked about the SWIFT Gamma-Ray Burst Mission. space solar power, & reflective mirrors in space to beam sunlight to the Earth. I asked our guest several questions about the Norwegian Space Centre & the Norwegian space industry. We learned that their industry makes many parts for satellites for NASA as well as ESA. He said the space awareness of Norwegians is good as they know quite a bit about space. Binary star systems, the Northern Lights, the southern hemisphere, Polar Lights, & the cause of the auroras were also mentioned. Near the end of the program, I asked about the impact of NASA budget cuts & program cancellations on the Norwegian space industry. As you will hear, what NASA & our Congress do does impact the Norwegian industry. He also talked about the IRIS High Resolution Spectrometer being worked on by Lockheed in the Palo Alto area. Before the program ended, I asked if the high launch costs impacted the Norwegian industry. He said no because they make parts for satellites & missions & are not directly involved in the launch side of space. We also talked about the rate at which solar knowledge was increasing, was there a role for the ISS in solar research, & the increasing role of Earth-based telescopes in solar observation. If you have comments/questions, please post them on The Space Show blog URL above. If you want to email our guest, please send it to me and I will forward it for you.

Dr. Robert Farquhar, Sunday, 3-25-12 (48.78MB; download) -- Guest: Dr. Robert Farquhar. Topics: Our discussion centered around his memoirs in his new book and his space involvement over fifty years. 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. Robert Farquhar back to the program to discuss his new book, "Fifty Years On The Space Frontier: Halo Orbits, Comets, Asteroids, and More." If you purchase the book using the following Amazon link, Amazon will make a contribution to The Space Show/OGLF: www.amazon.com/Fifty-Years-Space-Frontier-Asteroids/dp/1432759272/ref=onegiantlea20. Dr. Farquhar started out by talking about his early interest and work in aviation and space, gradually taking us up to and including the missions he has described in his excellent book. Among some of the points he made included that in the early years, there was much more independent freedom for those working on missions while today things are done by consensus, committees, etc. When asked if the missions were improved and the costs contained by the newer methods, he said he did not think so. Its an interesting discussion you will want to hear. He highlighted several of the early missions and we talked quite a bit about the halo orbit and Lagrange points. He also told us stories about plaques he snuck on missions, trying to arrange one mission arrival to coincide with his birthday and more. Great stories and for sure you will have a smile if not an outright laugh when listening to Dr. Farquhar. He also said all of the stories he was telling us were in his book. Later in the longer first segment we talked about human spaceflight and why he supports SLS/Orion. This discussion took us into a more extensive conversation about L1 and L2 missions in the Earth-Moon system. In the second segment, listeners asked about L4 with the 2010 TK7 asteroid, New Horizons, Pluto, Mercury, and more. Bob told us additional stories, including some about the photos used in the book. The JWST came up as did additional funding for NASA. Bob did not think more funding was needed but thought the existing money could be used better. The Kuiper Belt was discussed as were asteroid issues in general along with specific missions. Neat the end of the show, I asked Bob if his space work & expertise has given him perspectives on the existence of ET. This is a brief discussion you do not want to miss!

Dr. Phil Chapman, Friday, 3-23-12 (47.23MB; download) -- Guest: Dr. Phil Chapman. Topics: The status of our human spaceflight program, NASA, commercial space. 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 Dr. Phil Chapman to suggest ways forward to improve our space program, specifically the human spaceflight (HSF) program. Dr. Chapman started us off with an assessment that the NASA HSF program was at this time dismal. Among the reasons cited were the likely number of U.S. astronauts that would be flying to the ISS through 2020 per the Soyuz and the fact that the pilots for U.S. astronauts will either be Russian or working for Space X. All in all, he suggested that there might be 25-30 slots available and they would be filled by technicians. During this nearly hour long first segment, he continued to summarize the problems and challenges, then he switched to probable solutions from the commercial side with a focus on Space X, the Falcon 9, and Dragon. Phil had much to say about congressional support of SLS, the use of SRBs, and more. He talked about the commercial value in returning to the Moon or going to an asteroid for Platinum Group Metals (PGM). He indicated that future space activity had to be in support of settlement and commercialization. Dr. Chapman then took us into an economic discussion and the need for space to be expanding, growing and developing new markets. As part of this discussion, both of us and the listeners had much to say about our policy makers. This brought up the "sustainable" discussion that many of you have heard before. You do not want to miss Dr. Chapman's economic discussion in this segment. Near the end of the segment, we talked about RLVs and the probable cost difference between a commercial venture and one undertaken by NASA. In the second segment, Charles led off with a call suggesting a merger between Space X and Bigelow and simply bypassing NASA for everything. After Charles finished, Phil talked about one probable driver for changing the space game, space solar power (SSP). Dr. Chapman spent much of this segment laying out the case for SSP from a technical as well as economic/business perspective. We also talked about policy and Zero G Zero Tax. Public/Private partnerships were discussed and then Phil talked about international cooperation as compared to international competition. Don't miss this discussion. If you have comments/questions for Dr. Phil Chapman, please post them on The Space Show blog URL above. If you want to email Dr. Chapman, send your note to me and I will forward it to him.

Henry Vanderbilt, Thursday, 3-22-12 (40.29MB; download) -- Guest: Henry Vanderbilt. Topics: Space Access Society Conference, Phoenix, Arizona April 12-14, 2012. 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 Henry Vanderbilt to the program to discuss the upcoming Space Access Society Conference, April 12-14, 2012 to be held at the Grace Inn in Phoenix, Arizona. For the conference agenda, registration and full hotel information, visit www.space-access.org. During the first part of our initial segment, Henry provided us with an historical overview of not only the development and evolution of the Space Access Society meetings and conference, but also his own personal work in the space arena leading up to his excellent space activism of today which focuses on the space transportation issue. This is a comprehensive look at activities that have brought space exploration and development to today since about 1986. While Henry has been a frequent Space Show guest, this is perhaps the most detailed look we have had from him regarding his space evolution and the rise in importance of the Space Access Society (SAS). Later in this nearly hour long segment and until our break, Henry highlighted many of the speakers that will be at the conference. You can see the full list and the three day agenda at www.space-access.org/updates/sa12info.html. In our second segment, we talked about more of the speakers but mainly focused on those that would address policy and budget issues as not all of the SAS speakers are on the business/entrepreneurial side of space development. Some of the highlights included the NASA Chief Technology Office, ULA, policies for going beyond LEO, and advocacy on issues supported by SAS. As part of this discussion, we talked about SLS, ISS, Space X, depots, and budgetary pressures on NASA and key members of congress. If you have comments/questions, please post them on The Space Show blog URL. If you have questions for Henry about SAS, you can email him at space.access@space-access.org.

Michael Laine, Tuesday, 3-20-12 (52.19MB; download) -- Guest: Michael Laine. Topics: Lunar space elevator, general space elevator discussion. 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 Michael Laine for updates on his company LiftPort & their latest space elevator plans. Michael started the discussion with an overview of his involvement in the space elevator project, his company LiftPort up through its fiscal problems, the reestablishment of the company with intellectual property, & a lunar space elevator study from 2010-2011. He brought us current with LiftPort plans into 2012 plus what the company & his team have planned for the balance of the year. Michael talked about his team, issues relating to a lunar space elevator, how the Moon rotates/spins differently than the Earth, & how an elevator would be different than an Earth-based elevator which he said cannot be built at this time. He made the point that the lunar elevator could be built now, does not need a carbon nanotube ribbon & will likely go from Sinus Medii on the Moon to an orbiting spaceport at the Earth-Moon L1 point where there might be a Bigelow station with EELV or Falcon 9 flights coming up from Earth. He also said the early flights would be robotic but that both capability and capacity would expand to include humans. He was of the opinion that the basic lunar space elevator could be completed within a decade. Eric called in to challenge some of Michael's technical analysis. Michael offered to send the math analysis of the project to anyone requesting it. His email address can be found at the end of this summary. Later in this hour long segment, I asked Michael about business issues, the market, financing (public, private, both), ROIs, & more. As you will hear, this part of the LiftPort plan is unfinished. Michael's team has been confirming the math analysis for the project & has yet to refine their business plan/due diligence analysis. When pressed, he said the cost might be around $700-$800 million but they were increasing that to $1.5 billion to be a bit conservative. He also said this was for a small elevator with a payload capacity of 40-240 kg. In speaking about the commercial aspects of the project, he repeated many times throughout our discussion that they were focused on cash flows and the commercial aspects but first they needed certainty about reaching the technical "go" point. In our second segment, Michael continued his theme that they do not yet have the business plan components in place. I then asked if this was nothing more than a feasibility project? That seemed to summarize our discussion so far. Michael did point out that LiftPort already had two intellectual property (IP) assets so the company was positioned to make money even before the elevator project got going beyond the study phase. I pressed him for his public finance plans. His idea was based on the Railroad Acts which included bond sales guaranteed by the government with the government providing sufficient business revenues to support the bond guarantee. A listener brought up the issue of space debris & climbers. Michael pointed listeners to their YouTube channel to see their climber in action. Mars elevators were mentioned near the end of the program as well as LiftPort internships. We also talked about the recent Japanese company's announcement of their own elevator plans (Obayashi Corp.). Michael also suggested the space elevator conference (http://spaceelevatorconference.org). Please post your comments/questions on The Space Show blog URL above.

Duane Hyland, Monday, 3-19-12 (45.32MB; download) -- Guest: Duane Hyland. Topics: Guidelines for the Art of Persuasion in taking the case for space beyond the space community. 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 Duane Hyland to the program to discuss the guidelines for persuading others in an argument or debate. Mr. Hyland, a winning debate coach, provided us with important guidelines for making a persuasive argument. Our guest started with Aristotle and the three elements needed for winning the argument: Ethos (authority, credibility), Logos (logic), & Pathos (emotional). You can find out more from this concise summary: http://courses.durhamtech.edu/perkins/aris.html. Another statement of the argument was provided by Stephen Toulmin of Austria who later came to the U.S. In the 1960s, he developed CWI Model (Claim, Warrant, &Impact). Listen how Duane describes the Toulmin Model of Argumentation. You can read more about it on the web but here is a brief summary: www.forensicsonline.net/forum/uploads/1/827212498280123410.pdf. Check the section titled "Instruction." Once Duane explained the basic components of a winning argument, we talked about specific examples in the space enthusiast community as well as Space Show interviews some of my experiences in public speaking & in being part of panel discussions. One of the early points Duane made was that we can easily get carried away by our emotions, forgetting to properly frame the argument. Another point made was about the overuse of technology. I asked him about rants & Duane strongly advised against them. He talked about supporting the claim with facts, controlling an audience, & the effective & important use of humor/laughter. Duane talked extensively about needing a strategy & practicing your speech to make sure you speak naturally not robotic-like. In our second segment, we discussed more situations & the tools needed to counter them, but keep in mind that it starts with your awareness of these situations. Other issues discussed were age & differences in an audience, do we target a segment of the audience, do we engage in partisan politics & if so, how do we do it to be most effective. Duane pointed out that personal attacks don't have a place in winning debates & persuading others. A listener brought up writing Op-Ed articles & we learned the guidelines apply to this discipline the same as in debating & speaking. Other listeners asked Duane what he thought the most effective space speech was plus they wanted examples of effective space speakers today. We talked about the use of references as is done in debates. References or evidence, are important but note how Duane suggested evidence be used when we talk to others about space. The issue of pork as in NASA projects came up. The use of loaded language was discussed & our guest said we should always avoid using it. Another listener asked Duane for his top five debate topics. Space was not included but when I pressed him, he said space would have been a topic in the next five. In summarizing, he said we should rehearse our argument but remember to deliver it in a natural style. He suggested a few books at the end for those wanting more information. The primary title he recommended was "Argumentation and Debate: Critical Thinking for Reasoned Decision Making" by Austin J. Freely, 1999. You can get this book on Amazon using the following URL & Amazon will then make a contribution to The Space Show/OGLF: www.amazon.com/Argumentation-Debate-Critical-Wadsworth-Communication/dp/0534561152/ref=onegiantlea20. Don't miss his closing suggestions. Selected by: David Livingston [ stations ], Tue, 20 Mar 2012 17:23:02 UTC

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 Josh Neubert and for the first time, Dr. Larry Cooper, Program Executive for the NASA Centennial Challenges program. You can learn more about Centennial Challenges by visiting www.nasa.gov/challenges. For more specific information on the Night Rover challenge, visit http://nightrover.org. In our first segment, Dr. Cooper went over the history of NASA Centennial Challenges with a specific focus on the Night Rover Challenge. We also talked about the two other challenges going on at this time, the Sample Return Robot Challenge and the Nano-Satellite Launch Challenge. You can access the websites for these additional challenges from the NASA Centennial Challenge home page. Dr. Cooper talked about some of the successes of the program, including the glove challenge won by Peter Homer who has been a guest on The Space Show. Josh went into some of the details regarding Night Rover, specifically the draft Rules which are now out and open for comment. Josh also talked about the Team Agreement. He described the $1.5 million prize and the eligibility requirements for winning this prize. He then talked about the three levels of storage battery density in terms of winning the prize. In our second segment, Josh said it was opened for everyone from a garage entrepreneur to a large company. Larry talked about ideas for future challenges and asked listeners to suggest ideas to NASA. He then told listeners about the process for submitting future ideas, especially for the next five year. Larry and Josh both referenced earlier successful Challenge programs plus a few that were retired without anyone winning them. Several Challenge ideas came in from listeners including one on debris removal and Larry said that NASA Centennial Challenges was authorized to issue up to a $50 million purse! We talked about ITAR issues and partnerships for prizes with other space agencies such as ESA. Later in the segment, I asked about the history of prizes and our guests went as far back as the Longitude Prize regarding ocean navigation which was actually won by a clock maker. Other prizes and awards were mentioned in this historical review of the subject. When asked for closing comments, Josh reminded us to provide feedback on the draft rules and Larry spoke highly of prices having a positive impact on entrepreneurs, being a plus for tax payer funding, and for pushing the envelope for discovery and advancements with technology. If you have comments or questions for our guests, please post them on The Space Show blog URL above. If you want to email either guest, please send your note to me and I will forward it to the person of your choice. Selected by: David Livingston [ stations ], Sat, 17 Mar 2012 15:40:46 UTC
