We welcomed Bruce Pittman back to the show to discuss the emerging commercial space industry. During the first segment of our 90 minute program Bruce said this was the most exciting time every for commercial space, certain in his 30 plus year career.  He talked about there being a paradigm shift underway, NASA challenges and the progress made in just five short years.  He cited examples with COTS, commercial payloads to the ISS, SpaceX, and lots of smaller companies working with small satellites.  Other examples included the 3D printer on the ISS, the growth of spaceports, the industry spreading out into multiple states, and investment capital coming to the industry.  I asked about human spaceflight (HSF) and he said it was more challenging and demanding but was optimistic that launch costs would come down, especially if reusability enters the market.  Reusability would greatly assist in bringing more commercial options to the table even for HSF.  Jerome in the UK emailed to ask about a commercial space industry outside the U.S.  Both Bruce and I commented on Jerome’s question.  Harry emailed Bruce to inquire if going public was essential for pushing the emerging commercial space industry forward.  Bruce was also asked what excited him the most in the industry.  Listen to his choices. I asked our guest if he saw SLS as an asset to the emerging commercial space industry, being neutral, or being a detriment.  He believes there will be synergistic enhancements for both SLS and the commercial space industry through the development of SLS.  Don’t miss his full comments. Bruce was asked about commercial space ventures being able to finally close a business case and having more than just government as the customer.  Allison emailed us asking Bruce to define paradigm shift.  This also proved an interesting discussion.  Near the end of the segment, our guest was asked bout NEOs and commercial opportunities.  We also talked about two NASA papers in this segment.  The first, “Pioneering Space: NASA’s Next Steps on the Path to Mars” from May 29, 2014 can be downloaded at http://www.nasa.gov/sites/default/files/files/Pioneering-space-final-052914b.pdf.  The second paper, “Emerging Space:  The Evolving Landscape of 21st Century American Spaceflight,” can be downloaded at http://www.nasa.gov/sites/default/files/files/Emerging_Space_Report.pdf.  Just before the break, Paul asked about fuel depots for the commercial space industry.

In our second segment, we started talking about space settlement, pioneering, and space exploration.  Bruce explained the differences with pioneering making it possible to have a permanent presence in space by getting in place needed infrastructure and the basics for living in space.  Space settlement would be established after pioneering.  Exploring goes forth to find out what is out there and to return to tell about it.  A listener asked if going to the Moon was a pioneering step on the way to Martian settlement.  Later, Bruce said that pioneering will be driven by economics. In this segment, we also talked about property rights and benefit sharing plus the impact these two issues might have on the emerging commercial space industry.  Risk averseness came up as well.  As we were drawing to a close, Bruce mentioned how all of the industry was in a transitional period, including traditional aerospace.  He suggested things to look for over the coming months included more commercial activities on the ISS, the upcoming Bigelow module for the ISS, & the Google Lunar XPrize.  In closing, we talked about Silicon Valley and the industry as well as the lowering of barriers to entry for emerging commercial space companies.  Bruce also mentioned the Next Giant Leap Conference in Hawaii, Nov. 9-13, 2014.  For more information, see http://2014giantleap.aerospacehawaii.info.

Welcome to this 2.5 hour Space Show Classroom discussion with Dan Adamo, Dr. John Jurist, & Dr. Jim Logan regarding the recently released NRC “Pathways To Exploration: Rationales And Approaches For A U.S. Program Of Human Space Exploration.”  You can download the report for free at  http://www.nap.edu/catalog.php?record_id=18801.  In addition, the project referred to in the last part of this discussion by Dan and Jim, the “Aquarius interplanetary HSF transport” paper can be freely downloaded at  http://www.spaceenterpriseinstitute.org/2014/07/aquarius-a-reusable-water-based-interplanetary-human-spaceflight-transport.  Please note that our panel members used cell phones which caused audio issues which you may hear during the discussion.  Finally, as this program will also be archived on both The Space Show and The Space Show Classroom blogs, there will be two papers uploaded to each blog, one by Dan Adamo & the other by caller Dr. James Dewar. I will mention both in the summary below.  In the first segment, our panel members opened with their perspective on the NRC Pathways HSF study.  While there were similarities in their perspectives, there were also noteworthy differences.  After this comprehensive introduction, I asked our panel members about the study and space settlement or pioneering.  Each panel member had much to say on the settlement issue, including the need to solve the gravity prescription for long duration HSF or settlement.  Our panel members  said that for the most part, space settlement was out of scope for this report.  In this part of the discussion much was said about microgravity issues & the need to do on orbit experiments to determine the HSF gravity prescription.  Deimos was discussed as an initial better choice that the surface of Mars re microgravity issues.  Our guests spoke to the need of a short arm centrifuge on the ISS.  Jim spoke to the specifics of such an experiment such as 1 G at the head., 2.5 g’s at the feet for two hours a day to see how it serves as a microgravity countermeasure.  Our panel members mentioned that there already was such a short arm centrifuge built years ago by NASA and Wiley, http://www.nasa.gov/centers/johnson/slsd/about/divisions/hacd/laboratories/short-arm_centrifuge_laboratory.html.  The guests talked about unknown human factor challenges for going to Mars and long duration spaceflight.  Jim provided us with interesting statistics on human spaceflight totals since the beginning in 1961.  The panel members had much to say about the budget issues discussed in the NRC study.  Another point brought up was the study’s assumption that if we are not going to the surface of Mars, why even do HSF?  Near the end of the first segment, listener Carl brought up the well known plans for Mars settlement with Elon Musk & SpaceX.  This sparked quite the discussion so don’t miss it.

In the second segment, our panel talked about the value of the Pathways study, international partnerships and what they saw as contradictory statements, especially regarding the mission cost impact of such partnerships.  John mentioned the study’s reference to NASA education & public outreach which he thought was more focused on STEM & the development of more engineers rather than on educating the general public to be more knowledgeable about science.  The panel members  noted that there was little attention paid to the societal impact of not even having a human spaceflight program.  Dan & Jim agreed on the importance of educational outreach and shared their experiences with us from the employment with NASA.  Adrian in San Diego sent in an email suggesting the panel was being pessimistic and that China would not overthink issues and just do missions without full disclosure.  All three panel members had much to say in response to Adrian’s charge of being pessimistic.  They talked about being reality based, not pessimistic & why it was so important to be reality based.  The panel hit back hard on the charge of being pessimistic.  Dan & Jim said to be other than realistic was reckless and irresponsible.  Jim also said that being called pessimistic suggested to him that reality had violated the person’s ideology.  Jim would be happy to debate the issues with anyone in open forum.  This discussion brought Jim and Dan to talking about their Aquarius project which you can download at the above URL.  They spent some time discussing the benefits of their approach, noting how it addresses & mitigates many of the problems associated with a HSF mission to Mars.  They also spoke to the need for nuclear propulsion and talked about using water as fuel and very high ISP ratings with high temperatures.  During this discussion, Dr. Jim Dewar called in to suggest their ISP ratings were low, he explained why, and he talked about starting small to start flying and then improving as you go.  We did not know it but we lost John from the connection but Jim, Dan, and Dr. Dewar spoke to the NERVA project, and specifics about nuclear propulsion.  This advanced nuclear propulsion discussion was close to a half an hour near the end of the program.  Dr. Dewar was a guest on the program in 2008 & 2009 regarding nuclear propulsion & its history. He also authored two books on the subject.  Use the GuestSearch tool on our website to find his interviews which I suggest you listen to if you have not already done so.  I will also upload to both blogs the paper Dr. Dewar referenced in his discussion.  After the nuclear discussion, Adrian sent in another email titled “rebuttal.”  He challenged the panel members to do the experiments, not just to talk about them.  Jim, Dan & I challenged Adrian for his solutions to doing many of the needed & essential experiments. All of the panel members supported doing the needed experiments & have said so for decades.  Getting funding for the experiments, NASA approval, etc. is a challenge.  I then challenged Adrian to come to The Space Show as a guest with his solutions for doing the essential work & experiments rather than his just talking about how badly they are needed per his second email.  I hope Adrian does have answers and will contact me about coming on the show to discuss them with us.  Jim & Dan each provided closing comments focusing back on the study report.  They thought the report was worth it from the taxpayer perspective and that it would be used for references.  Jim did think the report was not as good as other government studies he had seen because it was so speculative, something all three guests addressed in their opening remarks.  An 11th hour call came from SLS John to talk about the ISP formula & temperatures Dan and Jim used in their paper Aquarius paper.  Dan authorized me to upload to the blog his written comments on the NRC Pathways study so you will find that document on both blogs as well.

We welcomed Michael Annis to the program to discuss his series of space & rocket history podcasts at http://spacerockethistory.com.  During the first segment, Mike told us about his background, being inspired by Apollo, and being a strong space enthusiasts going forward.  He strives for one podcast weekly.  Visit http://spacerockethistory.com/?page_id=344 for his timeline for existing podcasts with the newest on top.  Note that he started his series with his first podcast covering “Ancient Rocketry:  Standing on the Shoulders of Giants.”  As you will hear, he is still covering the Gemini program as his podcasts represent a detailed oral history in chronological order of events & missions that happened.  He does cover Soviet events plus events & rockets from other nations as applicable.  His sources are referenced in the podcasts but he does have a Source page, http://spacerockethistory.com/?page_id=27.  For this segment, we started at the beginning, talked about the history of rocketry and our space program.  One thing that I liked was his mention of the Flying Steam Powered Pigeon by Archtytas about 428 BC (see http://kotsanas.com/gb/exh.php?exhibit=2001001).  Listeners asked Mike questions about NewSpace, the Saturn V rocket, and for his favorite missions.  In this segment, Mike talked about the space interest of his students & their knowledge level of space history which was not good.

In the second segment, Mike mentioned Newton’s laws, especially his Third Law of Motion, especially action-reaction as he said rockets were based on this.  Our guest was asked about Mars as the focus and goal of human spaceflight and if he thought the US would likely lead a humans to Mars mission.  Another listener asked him about failures and he mentioned what he called a Flopnic, the Vanguard TV3 launch and the Soviet R7 rocket.  When asked about challenges to our space program, he cited budget problems.  We talked about the U.S. private sector which he supports.  Mike told us how to get his podcasts as they are available on iTunes and Stitcher.  Near the end of our program, Mike was asked about the Moon-Mars debate and his thoughts on the overall condition of our human spaceflight program.

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.

Please post your comments/questions on TSS blog above.  You can reach Dr. Lincoln through me.

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.
