We welcomed Dr. Don Lincoln back to the show to discuss his new book “Alien Universe: Extraterrestrial Life in Our Minds and in the Cosmo.”  During the first segment of our 1 hour 29 minute program, Dr. Lincoln discussed why he wrote this book, especially given his position as a senior scientist at the Fermilab plus his work in Cern at the Large Hadron Collider. After the introduction, he took us through major events, both physical and cultural that have fueled alien interest including the Betty and Barney Hill case, Roswell, and more.  He took us through these events with an actual historical timeline which put the events in a somewhat different perspective than we are used to hearing.  We also talked about the Drake & Fermi equations and the seven parameters of the Drake Equation, many of which have been upgraded due to new scientific information coming to light in recent years from the Kepler mission and other tools/events.  SETI was a topic of discussion as was the use of radio waves and light for ET detection.  The subject of alien abduction came up and Don pointed us to the 1835 media buzz known at the moon hoax appearing in the first tabloid style newspaper.  This was an interesting history lesson that was new to me and probably to many listeners as well.  Marshall called in to talk about Drake radio waves, the signal to noise ration, and a planet being either too close to the center of the galaxy or too far from the center of the galaxy which causes the planet to be a metal poor planet. Dr. Lincoln had much to on this subject.  Next, we talked about microbial life on Mars.  John from Ft. Worth called to talk about impractical physics given the need to cross interstellar space. Don agreed and talked about the possibility of using probes.;  The subject of technology & options such as a mother ship plus scout ships came up.  John and Don talked about the lack of objective studies and the difficulty in working with assumptions.  Don also talked about the high standards used in science which are hard to apply to the alien visitation theories.  Scientists are not usually inclined to lower their standards so true scientific studies on alien visitation are a challenge.

In the second segment, we talked about the Roswell event.  Our guest had much to say about this event so don’t miss this part of our discussion.  Some scientific studies were mentioned such as Project Blue Book. I asked about studies by other nations and scientists outside the U.S. We came back to microbial life off Earth which is an important study subject by scientists across many nations.  Near the end of the program, Dr. Lincoln talked about the idea of First Contact, Star Trek, and comments made by Professor Stephen Hawking.  In the concluding minutes of our discussion, I asked our guest about part of his subtitle, “Life in our Minds” & Don talked about how this subject has come to our minds.  He left us with a good summary and strongly urged us to separate sociology issues from astrobiology, the latter being a credible science in search of life off Earth.

We welcomed Stewart Money to the show to discuss his new ApogeePrime published book, “Here Be Dragons: The Rise of SpaceX and the Journey to Mars”  You can get much more information by visiting http://www.innerspace.net along with http://www.apogeeprime.com/prime/bookpages/9781926837338.html, and http://www.amazon.com/Here-Dragons-Rise-Spacex-Journey/dp/1926837339/ref=sr_1_1?ie=UTF8&qid=1411235694&sr=8-1&keywords=here+be+dragons+the+rise+of+SpaceX+and+the+Journey+to+Mars.  Remember, if you buy this great book through Amazon, use the OGLF Amazon portal (instructions on the OGLF & Space Show websites plus all archived programs on the blog and The Space Show website) & Amazon will make a contribution to The Space Show.  During the first segment of our 90 minute program, Stewart explained why he wanted to write a book about SpaceX to tell the story from the beginning up to current SpaceX history.  We spent lots of time talking about the early days including the Mars Oasis Project, the forming of SpaceX in 2002 and the three questions that Elon asked prior to starting the company.  Stewart’s book and our discussion take you step by step through the emergence of SpaceX through each stage of its development.  Even if you are familiar with the SpaceX story or the basics, you will learn much from the book as well as listening to Stewart as he narrates the SpaceX story and responds to listener email questions along with my comments.  Some of the questions asked him were for the biggest challenges Elon and SpaceX faced plus the most important successes.  He was asked for the origin of Elon’s interest in Mars and if the Mars interest was a company wide passion and belief.  In response to a question about the biggest SpaceX failure, Stewart said it was the inability to enter the EELV national security launch program on his timing.

In the second segment, a listener wanted to compare the SLS, Falcon Heavy, and MCT with one another.  Questions were asked about the unveiling of the Dragon V.2 as Stewart attended the ceremony.  Others wanted to know about SpaceX launch sites at the Cape & in Texas.  Andrew asked about SpaceX PR & damage control when necessary, Dana asked if SpaceX was interested in space tourism & Larry asked about reusability.  Stewart said it was a core value for the company.  Stewart provided us with a good, brief summary of our discussion and what he considered to be a priority take away from our discussion.

Please post comments/questions on TSS blog. You can reach Stewart through me.

We welcomed back to the program Dr. Mike Griffin.  During the first segment of our 90 minute discussion, Mike talked about human spaceflight (HSF) and the commercial space market.  He said exploration would be a government project or at least with government in the lead, especially if the commercial market was not there.  He threw water on the argument that our space policy was budget driven.  Instead, he talked about it being based on choices we make. It was not and is not about the money.  His comments throughout or discussion on this topic supported his argument.  He even said the cost of space for the U.S. taxpayer was around 15 cents/day.  This discussion evolved to one on the importance of leadership which we agreed was in short supply today.  Included in this discussion was Mike’s vision for our space policy & program, plus he explained its importance and value to our nation both today and for the future.  He spoke to the issue of what society wants and the choices it makes that shape our future.  Space should be part of our national policy debate and hopefully such a debate would enable quality choices to be made that keep us on the leadership edge with all nations.   Mike was asked who he thought would be next on the Moon and he said China.  We also talked about the private sector taking us back to the Moon with HSF.  He said that the private sector could do this, capital was not an issue, but for the private sector to do it there needs to be a closing of the business case which he did not see at this time.  SLS John called in & asked about space advocacy diversity which he said seemed to be at war with NASA & whatever the program of record might be.  Mike had much to say about this, especially about inefficiencies in government organizations and projects.  He also said if the private venture or industry cannot make money, then it should be a federal project. Many times during our discussion he said that there are things that a society should do just because they are hard & they don’t have to look good on the balance sheet.  John also asked about the RD-180 engine, Mike offered us his conclusion as to why we should be a new version of the RD-180 so that we do not continue being dependent on Russia for space related hardware, etc.  Later, he was asked about cislunar space development which he said should be a public enterprise.  He cited many examples and models supporting the public development of this important space infrastructure.  SLS was discussed.  Mike very clearly articulated the case for SLS today and again repeated that SLS future missions are about choices, not the budget.  Don’t miss his comments.  As the segment ended, Randy emailed a question asking for the rational & silver bullet for HSF.  In my opinion, Mike gave an excellent response to this question so don’t miss it.

In the second segment, Mike got some questions about NASA doing more R&D and even forming a NACA-like division or program.  We talked about NASA R&D, the need for a NACA-like program and more.  Dave, our caller, commented on leadership, then Bill in Denver emailed in a question about using fuel depots and smaller launch vehicles rather than heavy lift vehicles like SLS.  Again, Mike had much to say about heavy lift, including that while possible to do smaller vehicle launches., the numbers don’t pan out for efficiency.  You need to listen to this full discussion which also addressed some bogus assumptions regarding inefficient heavy lift decision making.  Nuclear propulsion and Vasimr came up, , then we again focused on vision that takes on big challenges because we can!  More was said on lunar colonies evolving to longer BLEO missions plus cislunar commerce, especially cislunar cargo missions.  Another listener asked about being dependent on the Russians for HSF to the ISS and if shuttle was retired too early.  Mike talked about having wanted to fly shuttle at a minimum rate annually until a new vehicle was operational.  We talked about the role of the congress and White House as compared to the role of the NASA Administrator.  Later, we talked about the role of public support and individuals petitioning congress on space policy.  Listen to his story about the Hubble repair mission.  I even asked if poorly written and fantasy driven letters to informed staffers helped or hurt the cause.  Listen for Mike’s response. In summary, Mike said his wish was that people would share is view that there are important things for society to do but that don’t look good on a balance sheet.  In the end, he said he was optimistic that his positive views on space would prevail and that when policy makers realized that China was going to put people on the Moon and what that would mean for the US, it would not be allowed to happen.

We welcomed back to the show Louise Riofrio to discuss her new book, “The Speed of Light.”  Remember that if you order this book through Amazon to use the OGLF Amazon portal so Amazon will make a contribution to TSS.  Instructions are on both The Space Show and our blog’s websites.  For more information, visit Riofrio’ s blog at http://riofriospacetime.blogsot.com. During the first segment of our 91 minute program, Louise told us about new developments and her work since her first Space Show appearance on Oct. 27, 2008.  She told her about her science work and related travels at JSC and her work with the moon rocks.  She also explained how her work with the moon rocks was important to human spaceflight, especially a return lunar mission and an asteroid mission.  She talked about why a lunar return mission was so important for science & why it was better to have astronauts on the mission rather than only robotic.  Out of this discussion came another SLS discussion as Louise pointed out the need for heavy lift for a lunar or any BLEO mission.  I explored her thoughts and opinions on SLS, asking her about the perspectives provided by those not supporting SLS.  In my opinion, Louise put forth excellent arguments in support of SLS during the show.  I even suggested she become the spokesperson for SLS and lunar return missions given how well she articulated and explained the need for SLS.  Louise also spoke about the distance from Earth to the Moon and the lunar orbit, referencing the LLRE (The Lunar Laser Ranging Experiment) from the Apollo era.  She used information from this device in comparison with three other measuring methods to support her theory that the speed of light is slowing down.  Listen to her explanation behind her theory assumptions.  Louise then mentioned the very accurate atomic clock soon to go up to the ISS, ACES (see http://www.esa.int/Our_Activities/Human_Spaceflight/Human_Spaceflight_Research/Atomic_Clock_Ensemble_in_Space_ACES).  She said this would be very helpful in detecting and clarifying the change in the speed of light.  John from Ft. Worth called with several questions and comments about the speed of light.   Next, Paul asked a series of email questions about time travel.

In the second segment, we started off discussing time travel and speed of light changes for a multi-generational human mission.  Louise introduced us to time dilation.  John in Montana asked about GPS timing & the change in the speed of light.   Christine emailed a question about an RTM mission and asked what might change if the speed of light is slowing down.  Next, we talked about Planck units and the equation GM=TC^3 which is the same as M=R=t.  Peer review was discussed as were the challenges of getting new theories introduced into the literature.  As you will hear, old ideas do not go lightly into the dark, so to speak.  Louise then talked about having discovered a lunar orbit anomaly and referenced her paper, “Calculating a Lunar Orbit Anomaly” which you can download at http://www.lpi.usra.edu/meetings/lpsc2013/pdf/2436.pdf.  As the program neared its end, I asked our guest about her idea that there might be a mini black hole in our sun.  Louise told us about her theory & talked in general about mini black holes.  Our last subject dealt with her interest in positive pressure suits for IVA purposes.

If you have comments/questions, please post them on TSS blog. You can reach Louise through her blog or me.

We welcomed Dr. Bill Rowe back to the program to discuss cardiovascular issues for human spaceflight & EVAs, plus many other issues pertaining to long duration spaceflight.  Note that we experienced serious phone line issues with Bill about 12 minutes into the program forcing us to stop for repairs.  Evidently the fiber phone lines now serving Dr. Rowe cause broadcast equipment problems.  Bill was able to go to a neighbor’s house to do the show but you will hear some line issues plus unusual cuts as I spliced together part of his opening to the point we were able to resume with a good phone line.  Once past that point, there were no further phone line issues.  During the first segment of our 2 hour 11 minute program, Dr. Rowe introduced us to his discussion main points and we began using his website for references throughout the show.  It is important to be on his website and go where he points at various times in the discussion (see http://www.femsinspace.com).  While parts of the discussion relied on medical terms and descriptions, our guest did an excellent job of breaking it down for us non-medical types to easily understand the information he was sharing with us.  Among the issues we talked about were cardiac issues that don’t present symptoms, plus the problems with increased adrenalin secretion in the body which happens in space.  Dr. Rowe spent significant time discussing the adrenalin issues citing known astronaut examples.  In fact when talking about the adrenalin levels in space, he said that within five days of being in space the levels are twice that of being on Earth.  Another issue brought up was possible cardiovascular damage for excessive exercise and here he cited the research projects he had been involved in with marathon running athletes.  He strongly suggested the use of regularly taken electrocardiograms on the crews while in space.  Next, Dr. Rowe talked about EVA issues, specifically cooling.  He explained other risks and made the case for future robotic EVA missions instead of human mission.  Before the segment ended, he had much to say about exercise in space.

In our second segment, Bill reviewed for us his comments on oxidative stress and suggested we follow along with his website submarine model, http://www.femsinspace.com/Oxidative_stress.htm.  A listener then emailed in that the ISS did have an ultrasound on board which could be used for the purposes Dr. Rowe suggested (see http://www.nasa.gov/mission_pages/station/research/benefits/ultrasound.html).  Bill talked more about lunar dust toxicity plus magnesium and calcium usage in space and in general.  He referenced former astronaut Jim Irwin losing consciousness for a brief time on the Moon & he provided the reference for that fact.  Rodent research on the ISS was discussed, then he got a listener question about possible different health standards for government trained and fit astronauts as compared to space tourists and possible private sector astronauts.  Near the end of our discussion, space tourism came up and he pointed out risks for the middle age, overweight segment of the space tourism market.  Bill spoke to pharmaceutical use in space and the issues with it.  Just before ending our discussion, he pointed out that for Mars he thought an all female crew was best given the advantages they have over men.  He did explain his comment.

If you have comments/questions, post them on TSS blog above.  You can reach Dr. Rowe through his website or me.

We welcomed Michael Listner back to the program for this update regarding specific space law issues and theories.  In the first segment of the this 1 hour 48 minute program, Michael talked about the proposed Asteroid Bill in Congress and how to maybe get some limited property rights for asteroid mining by being able to move a small asteroid as in the NASA ARM project.  Michael theorized that if one moves an asteroid, its no longer in its natural orbit and then no longer defined as a celestial body.  We spent most of the first segment and a good part of the second segment discussing this theory and why it might work.  When asked if it would apply to lunar property rights or other space property rights, Michael was clear that it only applied to a small asteroid that could be moved.  He also said it would require an administration to endorse such a plan and that it would be difficult to establish as customary and it would certainly be an uphill effort.  BJohn and others sent in email comments about this.  As you will hear from BJohn’s emails which I read on air, not every thought positively about Michael’s idea.  Michael also talked about other forms of international agreements being much easier to obtain than treaties.  He also said the property rights policy battles would be fought diplomatically.

In the second segment, we talked about the SpaceX-US Air Force litigation and the AF Motion to Dismiss.  Next, we covered the RD-180 rocket motor issue and Michael noted that a new shipment of RD-180 motors had been received.  He also said there was new information suggesting Russia might want to expand the mission time for the ISS (http://www.parabolicarc.com/2014/08/25/russia-agree-iss-extension).  Property rights and moving an asteroid came back as a topic in this segment & Michael again talked about treaties which he said were top down in policy making while transparency, etc. was considered bottom up policy making.  We talked quite a bit about property rights being US one sided and he said that the Asteroid Bill actually enabled those outside the U.S. to put their projects under U.S. law for U.S protection.  We moved on to cubesats and oversight/regulation issues.  Near the end, Michael updated us on the Code of Conduct in which there should be another draft emerging in the near future.  As the program was drawing to a close, I asked Michael for remaining 2014 legal issues that might get a 2014 resolve.  We looked forward to early next year & our guest commented on issues involving Russia, China, and ESA.

Please post your comments on TSS blog above.  You can reach Michael through me or using the email address he gave out on air as the program was ending.

We welcomed NASA Astronaut Dr. Rick Linnehan to the program to discuss animals and their place in space in history, the present, and the future, plus human concerns for long duration spaceflight.  During this one hour program, we stared off by asking Dr. Linnehan for an overview of the role played by animals in space, including looking to the future for animals for agriculture, research pathology work, comfort, & other purposes.  We talked about microgravity issues and countermeasures, then I asked specifically about taking chickens to Mars for feed purposes.  Our guest talked about the effect of microgravity on chickens and the egg laying process.  He said a few times that while we might likely evolve over many years, decades or even longer to having a larger role for animals in space, most of the ideas and concepts today are pie in the sky.  We talked about some of the animals that had been and are in space including lab rodents, fruit flies, some small fish and others.  Our guest talked about the space acclimation process for animals, including the small fish, and we learned that in many instances the animals acclimate to microgravity faster than humans.  Our guest mentioned the need for advanced propulsion for long duration human spaceflight and suggested that Mars was on the edge of the possible using chemical rockets.  Rick mentioned some of the other human factors issues such as radiation and psychological challenges.  We also discussed astronaut exercise routines and the countermeasure exercise equipment currently being used with efforts underway to redesign the equipment to be more effective and lighter.  Several questions came up about private sector humans to Mars missions and crew health.  When asked if we could do a humans to Mars mission now or by the early 2020s, our guest said yes but listen to the details of this discussion.  Also, with regards to the private astronaut missions to Mars or elsewhere, several questions arose about the conditioning of the private astronaut crew, what microgravity countermeasures and exercise equipment they would have on board, what routines they would strictly follow and more.  Our guest was mostly referring to space agency astronauts in terms of our readiness to do human spaceflight to Mars now or the very near future.  He was unable to address private astronaut missions or their details because they are unknown.  We did talk about gravity and the absence of it in spaceflight, both for humans and animals.  Advanced propulsion questions and comments kept coming up during the entire show. At one point, I asked how essential advanced propulsion was for long duration human spaceflight and he said there would be no long duration spaceflight without.  Listen for the details regarding his opinion on this issue. Doug called to ask about bacteria, DNA, cat implants and more.  Artificial insemination came up with regards to surrogate species.  Doug also raised questions about the size for a minimum viable population.  After Doug’s call, I asked what our guest thought the priorities should be for Mars human spaceflight.  He listed advanced propulsion technology as first followed by human quality of life issues which he described for us.  I also asked questions about crew compatibility for psychological reasons as well as the probable command structure for the crew on a long duration human spaceflight.  One listener asked Dr. Linnehan about the differences in a zoo vet as compared to the typical vet we use for our dogs and cats.  Larry emailed in to ask if an animal had ever been on a space walk.  Rick said not his knowledge, talked about the need for an animal EVA suit of which there are none, and when I asked about taking an animal with an astronaut on an EVA for research purposes, he explained why that was impractical.  The microgravity simulation work in the NASA neutral buoyancy pool came up and our guest said that for about every hour he spends on an EVA, he would have spend about 12 hours in the pool.  Near the end of our hour long discussion, Jack emailed in for the best goals for human space flight.  Our guest suggested evolving stage by stage with cislunar, La Grange points, lunar settlement and out further and further to other destinations as our capabilities and technology improved.  B John had emailed in a few questions about microbes and the sea plankton announced by the Russians as existing on the outside of the ISS.  While we discussed these questions earlier in the show, near the end I asked our guest his question about microbes traveling greater distances in space than humans have and if our missions that have entered interstellar space carry microbes with them.  In his summary, Dr. Linnehan stressed the importance of continuing to explore space, to leave our planet, set up settlements, and to do what we can to keep pressure on the policy makers as we know the importance of space development and exploration.  He supports the private/commercial efforts and missions and even suggested he would do a one way Mars trip to help open up a Martial settlement.

We welcomed Dr. Rachel Armstrong to the program to discuss the Icarus Interstellar Project Persephone-Living Architectures.  During the first segment of our 1 hour 37 minute discussion, Dr. Armstrong provided us with a bit of her personal history and background leading up to her interest in space and living architectures.  As you will hear, her medical experience and perspectives were critical to her connecting the body in a relationship with technology.  As our guest began introducing us to Project Persephone, Dr. Armstrong talked about the need to move from an industrial type society and economy to an ecological based system which she fully described throughout both segments of our discussion.  She talked about new ways of understanding and working with matter and microbes leading to new world views, new types of structures, and to space habitats that will evolve based on the needs of the crew.  During our discussion, Dr. Armstrong mentioned many of the leaders in applicable and related fields, their projects, and their papers so I suggest you have pen & paper handy to jot them down for your own research benefits.  Dr. Armstrong, in talking about living architectures, made the point many times over that we should start thinking in broader ways about the materials we use.  Don’t miss her explanation & discussion of this & other important concepts.  I also suggest you read “Designing a Sustainable Interstellar Worldship” written by our guest (http://news.discovery.com/space/private-spaceflight/project-persephone-icarus-interstellar-100yss-120920.htm).  We talked about today’s closed and open loop life support systems and how the future will be built upon the shoulders of today’s engineers and designers.  Dr. Armstrong introduced us to non-human matter in this segment, but we continued talking about it in our last segment as well.  Complexity was discussed, then listener Jack asked by email for our guest to describe the future starship with an evolvable environment.

In our second segment, B John asked if we should skip HSF to the Moon and Mars as distractions, instead focusing on habitable orbiting space stations and growing them into world ships. Don’t miss her answer.  Rachel talked at length in both segments about the manifesto and its purpose and place in ecological starship design.  Our guest also pointed out potential conflicts with solar system exploration and the Outer Space Treaty.  Heather asked Rachel if she would produce a reading and reference list given all the citations and references she offered us in our discussion.  While that might be forthcoming, do visit Rachel’s related website, http://www.blackskythinking.org. B John sent in a follow up email asking just how biologically independent humans are from the Earth and its unmanageable ecology.  Don’t miss Rachel’s reply.  Another listener asked about the concepts being discussed today appearing in sci fi literature and film.  Rachel talked some more about sim biosphere which will be a new upcoming project.  As we were ending, starship cities were discussed as was the Philips Microbial Home (www.design.philips.com/about/design/designportfolio/design_futures/microbial_home.page).  Among the many people referenced by our guest was architect Philip Beesley and his work (www.philipbeesleyarchitect.com).

We welcomed both Dr. John Jurist and Dr. Jim Logan back to the show to discuss spacewalks (EVAs), spacesuits, human missions to the Moon and Mars, to the Martian Moon Deimos, the newly created Space Enterprise Institute, & the new Aquarius Reusable Human Spaceflight water based launch vehicle.  During the first segment of our 2 hour 5 minute program, our guests started talking about EVAs.  Early in the discussion, Dr. Logan provided us with important & interesting statistics regarding EVAs, then we discussed the challenges with them and spacesuits.  We talked at length about the difference in EVAs and spacesuits for the Moon, LEO, asteroids, & Mars.  We also talked economics for spacesuits given the need for a specific spacesuit depending on the destination/mission.  We talked about new designs for one size fits all & for mitigating dust problems.  Jim talked about the medical complications regarding both lunar and Martian dust.  Our guests then suggested that EVAs will likely be phased out for robotic missions.  Doug asked several questions about this via email.  Also, Jim suggested that EVAs will evolve to the concept of Forward Deployed Humans in the Loop for Telerobotic Operations.  This concept was discussed several times throughout our program.

In our second segment, Jim started with an announcement about the Space Enterprise Institute (SEI).  When it goes live in the next week or so, I will announce it on the show so you can follow it  He explained SEI, its purpose & goals.  He then talked about the concept that both Jim and Dan Adamo have developed over the past few years, Aquarius which is a reusable water-based interplanetary HSF transport.  As soon as the SEI website is online, listeners will be able to download their peer reviewed paper for free.  During this segment, Jim talked about Aquarius, John added in some details, we talked about the need for nuclear electric propulsion and why, plus the role of water with this launcher.  Both our guests explained the advantages of Deimos for the early missions, plus the return shielding and reusability as the return goes to a lunar orbit using existing water.  Radiation shielding was talked about, including the needed water and needed Radiation Protection (RP) levels.  John pointed out one advantage of Aquarius was the use of an open loop life support system.  John in Ft. Worth called about the temperatures that Jim said were needed.  Jim explained the need for 3,000 degrees C.  Both guests offered closing comments about EVAs & the direction we might be heading toward the forward deployed humans concept.  Both guests said the telerobotic concepts discussed would reduce risks, timelines, & overall mission costs.

We welcomed back Dr. Doug Plata for this two hour two minute discussion.  NOTE THAT THREE SUPPLEMENTAL DOCUMENTS FROM DOUG WILL BE UPLOADED TO THE BLOG.  During the first segment, Doug introduced us to the topics he discussed at the recent ISDC conference in Los Angeles.  He talked about SpaceX and both the Falcon 9 & Heavy, Lunar ice, hollow ice, a concept he calls Moon for Mars, and more.  He also suggested that the Moon was not necessary for a Mars mission.  Additionally, while he certainly support a return to the Moon, he does not believe bringing back the VSE and Constellation is the way to do it.  I asked him how he got is interest in and start in space advocacy about 4 years ago.  Doug told us an interesting story, including how he was influenced by the LCROSS mission.  Michael Listner called to ask Doug about the WHY for the missions & projects he was advocating.  This was an interesting discussion though Michael got cut off due to a glitch at his end.  Tony wanted to know if Doug might be considering a start-up around his ideas in the near future.  Other first segment topics included ISRU, what makes space sustainable, and gaining the public interest and trust.  I asked him what among his ISDC topics was the least popular.  Listen for the answer.

In the second segment, Doug said people could find the lunar cots petition at http://www.lunarcots.com.  Doug addressed a question submitted by Tony regarding the use of water for radiation shielding.  Doug corrected some misunderstandings from his previous comment & went through the calculations in support of his conclusions.  We talked about a recent Mars One announcement for payloads for their planned 2018 mission.  Doug talked lunar cots, telerobotics, & benefits which he had sent me on an earlier show.  It is the three benefits documents that I will upload to the blog.  Doug had more to say on LCROSS & its impact on him.  He also told us about his newly made NASA HQ and commercial space contacts regarding lunar cots and cislunar.  As the program was ending, he talked about doing a special Flagstaff conference next year with a media event at nearby Meteor Crater.  Several times during our discussion, Doug cited Hops Blog for lunar and Mars lander/hopper ideas.  See http://hopsblog-hop.blogspot.com.

Please post your comments/questions on TSS blog.  You can reach Doug through me or his lunar cots page.
