We welcomed back Tom Olson for his traditional annual year in review show, this time for the year 2015. During the first segment of our 1 hour 45 minute discussion, I asked Tom to start off with the worst space event for 2015 rather than the best. Interestingly, he said it was the fact that another year has gone by without our flying people to space, either orbital or suborbital. This opened up a discussion about disappointments in the suborbital industry other than for Blue Origin which got the best grade along with SpaceX for their landing their rocket back on the pad after making it to space. As for the best, Tom mentioned several “bests” during the show but started out with the new commercial space legislation recently signed into law, specifically the part about funding commercial crew and U.S citizens being able to extract resources from asteroids. He spoke about the launch industry in general saying this was a near record year with 87 total launches. He talked about the ISS extension to 2024, commercial projects on the station and he said it would be better to design a commercial station properly than to try and commercialize the ISS. Tom then mentioned several entrepreneurial companies worth noting and watching including Planet Labs, Spire, Made In Space, also Sierra Nevada with the continuation of its Dream Chaser space vehicle. Listener Robert asked if his views on space solar power had changed in 2015. Tom said no but listen to his explanation. I asked Tom for the top space leaders of 2015. He had trouble naming a few other than Bezos and Musk. He said there were no heroes. All of the space men and women were heroes. Jeff from Denver asked Tom if he changed his mind on SLS/Orion from previous years. Again, Tom said no but listen to his full explanation. Another listener asked him if he thought 2016 presidential politics would influence space policy. Again, he answered with a no. Ft. Worth John called to talk about artificial gravity experiments that were needed, Falcon 9 landing the 1st stage successfully, plus he asked when the Falcon Heavy would fly.

In the second segment, Luis from Venezuela asked Tom about small scale laser beaming of power from powersats to landers and assets on the lunar surface. Next up was Dr. Lurio who put in a plug for Made In Space for a 2015 outstanding company award, then he talked about XCOR, responding to some of the recent management changes in the company plus the comments Tom was making about the company. Tom further addressed Made In Space and mentioned a 3D bioprinter. Here is the link to the story he mentioned about the bioprinter, http://medcitynews.com/2015/08/watch-out-organovo-biobots-launching-new-line-of-low-cost-3d-bioprinters. Tom spoke more about the Bigelow ISS BEAM Module experiment for later in 2016, then talked about the success of deep space exploration, JPL, and more. He mentioned running water on Mars, Cassini and Titan photos, New Horizons and Pluto and the Dawn Mission to Ceres. He also gave credit to Rosetta and the Comet 67P mission , then commented on the disappointment about the delay in the Insight Mars mission. Tom mentioned Putin’s reorganization of the Russian space industry to just Roscosmos, then he said the weirdest event of the year was the exoplanet discovery of the mysterious dimming in light value with some in the media reporting the possible discovery of alien ruins (see http://news.discovery.com/space/alien-life-exoplanets/has-kepler-discovered-an-alien-megastructure-151014.htm). Near the end of the program, Tom talked at length about important changes in the New Space Business Plan Competition. A listener then asked him about space films for 2015 and Tom commented on The Martian and television science fiction programming. He also mentioned the twins study on the ISS was nearing its end and Scott Kelly had set a record for the most time spent in space by an American astronaut. Before the show ended we talked about one way trips to Mars, Mars One and then Tom predicted that Mr. Musk will get to Mars before NASA. He concluded by saying that 2015 was an inspiring year for space on all fronts.

Please post your comments/Questions on TSS blog above. Happy New Year to all of you. Keep it safe, have a great celebration and I wish you all a terrific 2016! Thank you again for your Space Show support.

We welcomed back to the program Joe Carroll to update us on his work with artificial and partial gravity, plus his thoughtful considerations for what comes next for human spaceflight. I have uploaded three papers of Joe to The Space Show blog for today’s program. He does refer to these papers and presentations during the show so be sure to follow along by viewing them on the blog. During the first segment of our 1 hour 41 minute program, Joe said he preferred using the term partial gravity to artificial gravity. He talked 1 g issues, tests that can be done on the ground and the need to learn about gravity limitations for humans through ISS research. Centrifuge spin rates were a significant discussion topic in this segment. Here, he referred us to Appendix A page 8 for a two page discussion on early research on this subject. See his paper titled “Partial Gravity Biology Research Paper for Space 2015 Final” on TSS blog. Joe referred several times to the Twins & one year cosmonaut/astronaut study underway on the ISS, plus the Gemini 7 mission which answered several important microgravity questions. Later, Joe suggested we look at the chart on the third slide of his Power Point where he showed the gravity factor of major bodies in our solar system. This is an interesting discussion, don’t miss it. It also pointed to the importance of knowing the gravity prescription for Moon-Mars as it covers most of the solar system gravity ranges. Doug sent in an email about spin rates as high as 24 rpm. Don’t miss how Joe responded to Doug who then sent in a clarification email about upright exercise in a short-arm centrifuge. Again, don’t miss Joe’s reply. At this point, Joe started raising questions about why Mars, asking what were the economic reasons. He referenced our National Space Policy from 2010. Joe suggested the direction of the manned program was confusing at best. He talked about the remaining residual from the Apollo momentum and the Outer Space Treaty impact on future human spaceflight. BJohn emailed in about artificial gravity experiments with cubesats.

In the second segment, Tim asked several questions including one about using weighted clothing to offset microgravity. The subject of radiation exposure came up and here, Joe talked about the side effects of “fixes” which may cause even more problems than just the original problem being mitigated. He again referenced the Twin and cosmonaut/astronaut studies on the ISS now underway. Doug called regarding my earlier comments where I reference a past show in which many listeners did not think we needed to know the gravity prescription. Doug corrected what I said about his position but Joe thought there were solid advantages to know the gravity RX and to do so in LEO. You will find this discussion to be very interesting. In the latter part of this segment, we talked about being serious about humans going BLEO if we are not serious about finding out the gravity RX for humans. Safety came up and here Joe had much to say about the approaches regarding Orion and Dragon. Jack emailed in about our lack of seriousness on HSF BELO since we are not trying to learn the human gravity RX for long duration spaceflight or settlement. Joe went so far as to suggest convening a panel discussion to open up the discussion channels on what should be next for HSF. He listed potential participants but also invited listeners to send in to me or post on the blog their suggestions for participants. He said this was the perfect time for such a discussion as we entered the last year of the current administration. Doug sent in the final email saying that the challenge was more about how we go about deciding who’s vision gets the funding, suggesting this challenge took precedent over figuring out the next vision for HSF.

Welcome to our Open Lines show and my return to broadcasting given my post surgery recovery from my Oct. 1 spinal sugary. It was great to be back on the air. During the first segment of our two hour show, I updated everyone as to my post surgery recovery progress, I dedicated the show to the memory of our near friend Declan O’Donnell who passed away October 1 of this year, then I updated everyone on the progress being made on our new website development project and my ability to start fulfilling Indiegogo perk orders. As I stated, there have clearly been delays due to the first two weeks post surgery but we are getting back on track and I expect reasonable progress moving forward. As I explained I continue to have mobility limitations and sitting issues but things are improving all the time so I expect the delays will soon be a thing of the past. Several times during the program I mentioned booking future guests now that I am back on the air and suggested those of you that selected the co-host perk or the host your own show or be your own guest perk take advantage of the available dates for the balance of 2015 to bring your co-host guest to the program, or your host your own show to the schedule. Let me know and I will support you in invitations, etc. to get these programs booked with you even before the new website is launched. I also read an email from Matt from Switzerland who wanted to follow up from the earlier show with Ally regarding some sort of online virtual space advocacy training. If this interests you, post comments and your ideas on The Space Show blog. Matt will see them and maybe interested parties can get something going. Our first caller was Dr. Rowe who expressed misgivings about all the talk about being able to have humans walk on Mars by 2030. Dr. Row cited some of his well known and highly regarded medical research in support of his statements but as usual, committed space advocates challenged him. One was by text message to me which I did not read on air but was highly critical of Dr. Rowe wondering who he was and why in the world he would be talking about such things. Via a reply text I did tell this listener who Bill was and briefly listed his credentials for his research. I know his work is controversial and many listeners to this show do not support Bill’s conclusions but that does not invalidate his work. Doug asked Bill about running the numbers for what propellant it would take to spin up a craft with a tether long enough to get one gee but relatively low RPMs as the subject moved to needing to be in 1g and maybe even marginally less gravity would not work for humans. Lots of discussions followed about the gravity prescription issue, the need to know it for BLEO spaceflight, then Doug expressed his ideas of why it was not so important to know the gravity prescription at this time. Don’t miss Doug’s full comments on this subject and see if you agree with his perspective or not. Bill had some other medical issues to talk about, especially cardiology issues with Irwin and Armstrong. I have tremendous respect for Dr. Rowe’s work though I am not qualified to do any type of due diligence on it as I am not a medical doctor. Still, knowing it is controversial, especially with segments of The Space Show audience, I urge space cadets to be more open minded rather than married to agendas. In the end, Dr. Rowe’s work may prove more valuable and important than many think or would like to think. After a decent discussion with Dr. Rowe and listeners on related topics to Bill’s phone call, we started talking about the movie “The Martian.” This discussion took us through the rest of the show with breaks here and there for different or related topics. Everyone who called to talk about the movie like it and we did have some fun discussions about the movie and maybe some different scenarios.

In the second segment, John from Freemont, CA called to talk about the movie. he also talked about the gravity prescription and the plans by the SSI to do some sort of gravity prescription experiment. I talked about that as I have done shows on it and spoken to Gary Hudson about their efforts to fund this experiment,. He also mentioned the SpaceGAMBIT Organization which sounds very interesting. Check it out at www.spacegambit.org. June from Tucson emailed us wondering why there was criticism of the NASA Roadmap To Mars. I started answering her somewhat reluctantly but Doug called and I passed the response to Doug who handled the reply to June with a few side comments from me. In the process of talking about the roadmap, we talked about going to Phobos, cislunar development, SLS launches & much more. Doug then spoke about the movie which was the main reason for his call. During the conversation I incorrectly referenced a Dr. Lurio text to me over the weekend but fortunately Charles was listening to the show, sent me the correct text which I read on air. Charles then called the show and we had a good discussion about the movie, sci fi in general, and certain issues surrounding the movie. He also went into detail on the three items that made him see Hermes in the context of 2001. Advanced propulsion came up and several us wondered why nuclear propulsion was not a NASA solution to the rescue of the Martian. Here, we talked about the movie being about a NASA government program, not focusing on commercial or Newspace. Dr. Lurio offered a reason for this and I reminded listeners of this topic on the interview we did with Andy Weir several months ago. John Hunt called and we talked about audience and age differences with the movie. The last caller was Tim from Huntsville who saw it with friends, including non-space cadet friends. The non-space cadet friends liked the movie as much as the space oriented people liked it.

We welcomed back Gerald Driggers to discuss his August 10, 2015 Space Review article, “Reduced Gravity: The 400-kilogram gorilla in the room.” You can read & download this article at www.thespacereview.com/article/2802/1. During the first segment of our 1 hour 42 minute discussion, Gerald talked about the old concept to put a centrifuge on the ISS but of course that never happened. Much of the first segment our guest and listeners lamented the lack of attention to mitigating problems caused by microgravity by developing some form of artificial gravity as the standard mitigation tool. Gerald referenced several studies in support of the need for artificial gravity, including one only a year or so old. Listeners asked him about minimizing travel time to a destination, say Mars, as a way of mitigating microgravity issues. We talked about that but Gerald pointed out that at the destination you would still be in a less than 1 G earth gravity environment so what then? I asked Gerald if being stuck in LEO for decades might have contributed to the lack of NASA progress in this area. Kelly sent in an email asking several things, including a question about spin rates. Kelly also wanted to know why artificial gravity had been ignored for so long, suggesting the possibility that advocacy groups disregard it. I did not support Kelly’s contention as I have done many Space Show programs with advocates pushing for artificial gravity and even coming up with their own plans on how to achieve it. Gerald was asked about tethers. His response triggered a lengthy email from Joe Carroll on the subject which I will post for Joe on the blog for this program, then Joe called the show in the second segment. Gerald was asked about artificial gravity work going on in other countries & with other government space agencies. He also talked about the need to really just test for Mars and lunar gravity given the relationship of these numbers throughout our solar system to other planets and moons.

 

In the second segment, Gerald talked about his science fiction book series, “Earth Mars Chronicles” plus the long scale settlement of Mars. At this point Joe Carroll called to talk about his email, tethers, and the artificial gravity issue. Don’t miss the fine discussion with Joe and Gerald they brought up many facts about the situation, the 2010 National Space Policy and more. Joe referenced the Fresno Underground Gardens as a possible example of underground living which he said would be necessary due to radiation. There would be no on the surface living. He also talked about the need for a colony to expand internally and the challenges in setting up an ecosystem on another planetary body. Joe introduced us to other issues such as the need for a gut bacteria study on the ISS and the differences between genders in reduced gravity though that information is not gathered. Given that Gerald described himself as a Mars guy, not a Moon guy, I told him about the New York Times Op-Ed that appeared today, “Let’s Not Move to Mars” by Ed Regis. You can read the article at www.nytimes.com/2015/09/21/opinion/lets-not-move-to-mars.html?smprod=nytcore-iphone&smid=nytcore-iphone-share&_r=0. If you do read it and I hope you do, make sure to read the comments as well. Dr. Doug was the next caller. Doug and Gerald also had an interesting discussion as Doug suggested there was no need to do artificial gravity experiments in LEO, instead go directly to the Moon and do them there. This of course presumes we are going to the Moon. I talked with Doug about this as I think returning to the Moon, as much as I would like to see it happen, is still an unsupported assumption, especially if we are looking for the government to do it. This opened up a discussion about the private sector with Gerald saying he thought progress was more likely coming from the private sector than NASA regarding the issues talked about today. I pointed out that if we had private Bigelow space stations and somewhat affordable launch, then we might see this type of research undertaken if it was in the interest of a company to do so. Doug and Gerald continued their discussion which you don’t want to miss. As the show was ending, Gerald told us about his new e-book coming out on Kindle for just 99 cents on October 1, “Martian Sniper.” From what he said about it, it sounds like a winner so be sure to download and read it.

We welcomed Dr. Doug Plata back as our guest to discuss his paper which is on TSS blog for your perusal, “Achieving Early Earth Independence Through ISRU and Sufficient Supply.  During the first segment of our 1 hou 45 minute program, Doug told us the genesis of his ideas and concepts culminating in his submitting his paper to the NASA Challenge InnoCentive Challenge (www.innocentive.com/ar/challenge/9933746).  After referencing the NASA Challenge, Doug started describing his ideas in detail.  Much of what he described he said was summarized in the Introduction of his paper.  We talked about both the Moon and Mars but Doug explained that the competition was focused on Mars so he also focused on Mars though he still supports the Moon and cislunar development as the rational and initial starting points.   Issues he discussed included supplies, types of potential habitats, the definition of and clarifications for mass independence including defining both self-sufficient and self-sustaining.  He also brought up the earth return option and more.  BJohn sent in several questions but his initial one asking about becoming 90% Earth independent led to a most interesting discussion.  While Doug’s paper does not have page numbers, check out Table 3, “Estimated Equivalent Mass Independence.  Doug took us through the critical numbers and his analysis so don’t miss this important discussion.

 

In the second segment, Doug suggested three rationales for the settlement.  One was to push technologies needed for sustainable living in space.  The second was the big one according to his perspective and focused on reducing the resupply costs for the settlement.  The third one was also big and focused on assuring survival of the human species.  He discussed each rational in detail.  As part of the discussion, he referenced a space settlement as an insurance policy for humans, he talked about the earth return option, radiation, GCRs,  and more.  He also showed that by leaving the crew on Mars for an extra year, the mission would be less costly.  Listen to his discussion about this and see if you concur with him.  Doug was asked about the previous program with Al Globus and LEO settlements, especially over the equator.  He said that such settlements, while potentially interesting, cannot be self-sufficient or Earth independent and his focus was on gaining Earth independence.  Again, don’t miss this discussion.  Gravity, artificial gravity and spin rates were discussed as was the concept of self-sustaining versus self-sufficient for a colony.   Doug advocated for using the word colony rather than settlement but I took issue with that, especially if one hopes to communicate with people including Congress outside the space industry.  As the show was ending, Paula asked Doug about the fact that space settlers may not want to achieve Earth independence and it seemed his work was formulated around the assumption that everyone wanted Earth independence ASAP.  This was a great last question and discussion.  Doug provided a good summary of today’s discussion as we closed the show.

We welcomed back to the show Greg Meholic to speak about advanced propulsion concepts, rocket reusability, and much more.  During the first segment of our 84 minute program, Mr. Meholic first defined what he meant by the term advanced propulsion.  Given this definition, we moved forward to discuss various concepts, propulsion methods, and propulsion research. During this segment, we talked about several propulsion technologies and Greg said thumbs up or thumbs down to their being advanced propulsion.  When it came to nuclear, Greg classified it as an alternative propulsion method, not an advanced propulsion.  Again, don’t miss his definition.  We talked near and intermediate term advanced propulsion concepts though it does not appear anything is really close at hand.  His timeline for a possible advanced propulsion technology was around 20 years.  He said not only do we need to understand the physics much better,  but the propulsion method much compete with current systems and produce benefits including cost benefits.  As far as choke points on advanced propulsion, he said understanding the fundamental physics involved was a big one.  We then talked about funding which is now mostly from companies and other private investor oriented sources.  I asked lots of questions about funding, especially how does one know when the point is reached to either kill the project or keep it going.  Don’t miss what he said about this.  Listeners also asked many questions.  In replying to one listener, he said it would be hard to beat chemical rockets to LEO but the door opens up BLEO though the Moon can be done with chemical rockets.  When asked about the anti-nuke movement and the impact on the nuclear rocket, he had some interesting observations, especially regarding the views of younger people.  When asked for leading advanced propulsion people and concepts, he mentioned former Space Show guest Dr. James Woodward and his work with Mach’s Principle several times during our show.  Greg was also asked about the work of Dr. Sonny White at JSC for warp drive and M drive.  Greg had much to say about his work including Q thruster and M drive.  John from Ft. Worth called in to talk about M Drive & Mach’s Principle along with gravity and magnetic frequencies.

In the second segment, Ashley sent in an email asking about going to the Moon and Mars for settlement and sustainability, wondering if advanced propulsion was needed for either location.  You might be surprised by Greg’s response to this question so listen carefully.  He did say there would be different requirements for the Moon and Mars.  With Mars, he also spoke about radiation and travel times.  Greg then had some things to say about artificial gravity.  One of his comments was that if we understood more of the physics, an eventual advanced propulsion system might enable an artificial gravity system without spinning or the need for tethers.  Brad in Tucson sent in a note asking about reusable first stage rocket launch systems.  Greg was delighted with the question as he works on such systems in his day job and he had much to say and offer about reusable first stage rockets.  He went through a brief summary of some of his work plus those attempting to design such systems including SpaceX.  I asked about a payload penalty with reusability.  Don’t miss his answer.  Our next caller was Marshall and he took us back to the artificial gravity discussion.  Marshal was asking questions about the amount of time spent in 1g as opposed to various fractional gravity loads.  As the program was ending, Greg received the final question which dealt with comparing the quality of government research to private sector research.  He reminded the listener that there very little to no government research funding for advanced propulsion, that it was almost all private sector funding.  He said the private funding was investor based so it comes with a commercial profit focus.

We welcomed back Dr. Robert (Bob) Zubrin to discuss the upcoming Mars Society Convention in Washington, DC from August 13-16, 2015 (see www.marssociety.org/a/marssociety.org/www/conventions/18th-annual-international-mars-society-convention). During our 1 hour 45 minute program without a break, Dr. Zubrin not only told us about the upcoming Mars Society Convention for 2015, but talked about Human Spaceflight (HSF) to Mars by addressing many specific issues, concerns, and topics.  Starting off with the Convention, it is August 13-16, 2015 at the Catholic University of America in Washington, DC.  Special hotel prices are available at the Phoenix Park Hotel (see www.marssociety.org/conventions/18th-annual-international-mars-society-convention/hotel-and-transportation for reservation details).  Bob told us about the keynote speakers but also the special format this year for debates. Several topics will be debated including Moon vs. Mars, Mars One feasibility with the MIT team and Bas from Mars One, how best to achieve commercial space plus other topics.  Bob then started getting questions from listeners & myself on a wide variety of Mars HSF mission topics.  To start with, I asked Bob to comment on what several recent Space Show guests have said about our not being ready for HSF to Mars for a variety of reasons including radiation, other human factors, the costs, and the trip risk which would turn it into a survival mission and nothing more.  Before Bob responded to my specific question, he commented on the recent radiation paper, “How a trip to Mars would mess with your brain.”  Bob was very critical of this paper and spent time going through it and showing where he believed it to be bogus.  You can read Bob’s critique at www.marssociety.org/home/press/announcements/invalidclaimsmadeforwhathappenstoyourbrainonthewaytomarspublication.  Bob spent a good amount of time debunking the original article so don’t miss his comments.  Before moving on, I again asked Bob to respond specifically to what my guests had said as none of them mentioned the paper in question.  We had an interesting discussion on risk taking and the role of government as part of our discussion.  John in Florida called to ask about the concept of a nuclear explosion on Mars per Space Show guest Dr. John Brandenberg.  This led to questions about shortages of PU238, space policy & political leadership. Doug had questions about an Earth Return Mission and later he eventually called in to get a more precise answer to what he was asking.  We talked about one way missions, how best to explore Mars, and the responsible way to tackle the eventual settlement on Mars.  Emmet from NY called in to ask about Elon Musk Mars and NASA plans and why they seem to ignore going for artificial gravity.  Again, Bob had much to say about this issue which he said was different for Musk and NASA.  He felt Musk would address it as the challenge became more real for him.  As far as NASA goes, he said it was criminal to have avoided the issue for decades.  Don’t miss his comments.  Jackie emailed in a question about character in the book “The Martian,” wanting to know if crew were stranded on Mars could they actually do some of the things the character in the book did to survive.  You might be surprised by Bob’s answer.  Matt in Germany asked a question about Mars via the Moon, BJohn asked about the use of a cycler for Mars transportation & Kirk called to talk about an article he had read about fossil ice at Valles Marineris.  Kirk will post a comment about this on the blog after the show is archived.  Next up was the subject of terraforming Mars. Bob had much to say about this plus he offered a possible terraforming timeline. Doug then wanted to know if Bob was referring to paraterraforming when he mentioned the use of Domes on the Martian surface but Bob said no.  Tim called to talk about the radiation paper discussed earlier and mentioned a second experiment saying that antioxidants negated the radiation effects. Bob was not familiar with the second study but summarized his comments about the paper.

BJohn emailed in about rocket advances from the Saturn V for a Mars mission, we talked about what it would mean to use a Falcon Heavy for Mars missions, then Marshall called to inquire about sources of power on Mars, particularly nuclear and getting a large enough nuclear reactor to Mars.  Marshall and Bob talked about a Topaz like reactor.  Another question came up about using the Martian moons for the early human missions rather than Mars.  Bob explained why in his mind this was not a good idea.  He then compared the radiation dosage of long term ISS usage for ISS astronauts to the transit time and radiation dosage for a Martian crew.  Don’t miss what Bob had to say about this.  In Bob’s concluding comments, we focused on the upcoming convention but also on the importance NASA and a HSF mission to Mars in the context of the world today.  This is an important part of our program so don’t miss it.  In concluding, Bob said “It is time again for NASA to astound the world to show what free men can do.”  You will likely hear me use Bob’s closing statement on many future Space Show programs.

We welcomed back Dr. Michael Schmidt for updates and more information regarding Personal Spaceflight Medicine. Note that the abstract referenced in the second segment has been uploaded to the blog for this show.  During the first segment of our 92 minute program, Dr. Schmidt defined personal spaceflight medicine for us & talked about targeting individuals for specific countermeasures to human factors risks for longer duration spaceflight safety.  We talked about artificial gravity and radiation with our listeners asking questions about both fields.  Our guest cited several examples to make his point.  At one point he talked about the current twin study underway on the year long plus ISS experiment with a Russian cosmonaut as well.  Questions were asked about using pharmaceuticals in space, how they might react with different people, and the distribution methods so far which are not great.  At one point, Dr. Doug emailed in asking about the use of omics for space travel issues and if in fact the use of omics would reveal even more questions that cannot be answered, ultimately delaying long duration HSF missions even longer than they are delayed now.  Don’t miss the guest response to Doug’s question.  Kris emailed in asking about the use of deliberate hypothermia to store Mars bound astronauts, and then another Doug question came in about selecting the best people based on omics for a mission.  Near the end of the segment, I asked our guest if he had done work for Mars One. He explained their limited capacity relationship which I assume ended.

In the second segment, BJohn asked about the possibility of astronauts sleeping in a small vertical centrifuge.  Dr. Rowe called to talk about the issue relating to pharmaceutical use in space.  he talked about delivery methods, malabsorption, etc.  Later, Dr. Schmidt brought up the damage done from sleep deprivation and showed how this is a potential problem for space missions.  Doug emailed in a question about GCRs and radiation, then Dr. Schmidt talked about his new paper on BDNF with his associate Dr. thomas Goodwin, “Protecting Neural Structures and Cognitive Function During Prolonged Space Flight by Targeting The Brain Derived Neurotrophic Factor Molecular Network.”  We talked about BDNF and spaceflight, exercises, mitigation measures, and more. He referenced Mars simulation, behavioral issues and more. You don’t want to miss this discussion.  Dr. Schmidt provided us with excellent closing remarks.

We welcomed John Putman to the show to discussed neurofeedback in the context of astronaut peak performance training for both long and short duration spaceflight missions.  During the first segment of our 1 hour 26 minute program, Mr. Putman explained biofeedback and the specifics of neurofeedback, neuro-diagnostics and electroencephalography (EEG).  He also explained the linkage of this research to astronauts for both long and short duration human spaceflight missions.  Much of our fist segment provided the groundwork for our discussion, addressing the fight or flight response which is automatic, sensorimotor rhythm (SMR), and more.  Our guest explained how the training is conducted and how it works.  Also discussed was seizure disorder and space adaptation syndrome (space sickness).  Listeners had many questions for our guest including if it was being applied to or made part of suborbital flight training for participants.  Beverly wanted to know if astronauts would have time to do this type of training given how their schedules are planned.  Microgravity came up and John spoke to the fact that humans were 1g and it was simply not known what type of effects would befall humans in prolonged microgravity, up to ten years or more, even with some artificial gravity for mitigation.  As the result of another listener question, John spoke to the fact that the Moon was much closer, only three days away and possibly a good training ground for understanding microgravity, neurofeedback in space and more.  Michael Listner called to support Mr. Putman’s comments and then he brought up the Mars One project which both John and Michael discussed for a few minutes.  As the segment was about to end, a listener asked if the astronauts would be too “macho” to do neurofeedback training.  John said it was actually peak performance training & that much had changed today so he did not see attitude as a problem.  He even cited training feedback with Edwards AFB test pilots and the need to disengage from your stressful activity.  BJohn got in a question about rotation and artificial gravity and Kelly called from Phoenix to inquire about the training and its impact on fluid redistribution related to microgravity.

In the second segment, BJohn led off with another question about using the training to overcome sensitivity to bad smells thinking about sulfur on Mars as a possible example.  John was also asked about integrating neurofeedback training into missions using newly designed hardware such as the Dragon V2, Orion, CST`100, and Dream Chaser.  We talked about technology improvements and the likelihood of soon being able to do some of the training on a small device such as a smartphone.  I asked John about other space agencies doing astronaut training in this area.  He mentioned ESA as well as the Dept. of Defense and athletes interested in peak performance training.  Joan asked him about ISS experiments.  He said none yet and explained the difficult challenges he has had as a small business getting an experiment on the ISS.  We talked about possible gender and race differences but he said there were none and then we talked about sleep loss and how the training mitigates that problem.  John also talked about NASA, I asked about any interest by private space companies such as Bigelow and SpaceX, plus I asked if there had been an experiments with the Navy and submarines.  Visit his websites, http://www.eeginfo.com and http://www.jputmaneeg.com for more information.

We welcomed back Dr. Doug Plata to the show to discuss his ideas and concepts for an initial lunar base which he named Lunar Base One.  Follow along with this important website.   http://www.cislunarone.com/lunarbaseone.htm.  Be sure to click on the link in the upper left hand corner to download the Lunar Base One Reference Material. In the first segment of our 2 hour 1 minute discussion, Doug focused on introducing us to his Lunar Base One concept and Lunar Cots.  To follow this discussion, make sure you go to the Lunar Base One website per the above URL as he follows the information on that site for our discussion.  During Doug’s discussion, he took calls and emails from listeners on a wide range of associated topics, questions, and comments.  Listener questions covered telerobotics, wireless power transfer, artificial gravity & the use of a centrifuge at the base, wired power as in missile wire, laser beam power, battery usage, lunar dust, radiation, water, a lunar greenhouse, and check lists re solar panels, propellant, fuel cells, radiation, and more.

In the second segment, Eric called using a cell in Florida to discuss robotics over humans.  Later, Doug was asked if returning to the Moon would divert resources needed for going to Mars, the moons of Mars, or even an asteroid.  Don’t miss his response to this question.  BJohn asked about line of site communications with Earth or if there would be a need for lots of communication satellites.  Doug and John from Ft. Worth had an interesting discussion on several key points, then Doug spoke to lunar tourism, the transportation needs, then I asked him about changing space policy.  Specifically, I asked what he would say before Congress re changing our policy as to why the Moon were he to testify before both House and Senate committees.  Give your ideas on this on the blog because no matter how cool the technology and engineering may be, without a policy to go back to the Moon, most likely nothing will happen.  Rasmus called from Toronto suggesting the use of mylar over a small crater. You don’t want to miss this discussion.  As the show was drawing to a close, Doug spoke about his return to the Moon track at this year’s Space-Access Conference  which will be in Phoenix in late April.  He finished up his discussion talking about artificial gravity, the use of a long arm centrifuge on the Moon running at about a 5.4 RPM by the lunar team.  He also spoke about inflatables and what he learned in his discussions with the University of Maine professor.

Please post your comments/questions on The Space Show blog above.  You can reach Doug at the address on his website or through me.
