We welcomed Dr. Mark Shelhamer, Chief Scientist of the NASA Human Research Program to the show to discuss the critical risks associated with BLEO long duration HSP. You can hear his FISO talk on this topic from April 2, 2014 at http://spirit.as.utexas.edu/~fiso/telecon/Shelhamer_4-2-14/Shelhamer.mp3.  His associated Power Point can be downloaded at http://spirit.as.utexas.edu/~fiso/telecon/Shelhamer_4-2-14/Shelhamer_4-2-14.ppt.  During the first segment of our 95 minute discussion, Dr. Shelhamer started off saying  we would be talking about beyond low earth orbit only and that many of the risks are unknown since we have very little experience with BLEO.  Much of what we do know is extrapolated from our current knowledge base plus our Apollo experience.  Next, our guest defined three major areas/issues.  First he listed medical issues which he later described as onsite medical treatments for various complications, illnesses, surgical needs and such.  He classified physical deconditioning issues such as muscle and bone loss issues, cardio vascular issues in a different category.  The second group he identified had to do with radiation, and the third group included psychological-social issues.  I asked about Microgravity not being in the top three and he said because those issues are likely a constant for both LEO and BLEO missions.  He then talked at length about the challenges needing countermeasures/mitigation.  He did not say these were showstopper challenges but they do require effective countermeasures.  For example, he said humans could probably survive a trip to Mars today providing the hardware & life support was up to the job but their goal is to get the crew there in good condition, to be able to do effective work, and to return safely.  He did not think those goals could be obtained today.  I asked if money was a primary issue and it was not though he said more money is always helpful. He talked about the time needed for some human studies, team studies, and research, sometimes extending even longer than a year.  He then took us through the three categories to tell us what NASA was doing & how it was doing in that research area. You might be surprised by what you hear.  I certainly was.  Later, we talked about ocular/vision issues which are now getting front page attention.  He explained the latest theory causing the problem as possible fluid shifts.  Listen to this discussion.  Note that once we start with BLEO HSF, we may find other problems that do not now show up now.  Also, we may develop a countermeasure for one problem but that opens the door to lots of other problems currently unknown.  One tool he talked about that was being tested on the ISS Russian sector was lower body negative pressure.  Artificial gravity was a big part of our discussion.  While everyone is enthusiastic about it, he made the point of saying we don’t know the needed spin rate nor do we know what level of gravity is needed for humans or for how long. Just spinning a spacecraft without knowing this information is unlikely to be successful let alone cost effective or economic. He also pointed out that artificial gravity is costly, requires lots of energy, a huge spacecraft which means lots of mass to orbit, & to do it, it needs to be done in a way that maximizes the benefits for the crew.  Without knowing the precise spin rate and gravity needs for humans plus how long the crew needs to be in artificial gravity, it is likely it won’t be done just for cost and economic reasons alone.  Charles emailed in about bed rest analog studies.  Joe sent in a question about lower back pain & spine issues.  As the segment ended, I asked him if humans were lousy candidates for BLEO spaceflight.  Don’t miss his answer.

In the second segment, we took a call from Dave about nuclear submarines as an analog for HSF studies.  Our next topic was space radiation which our guest discussed in detail.  I then took two email questions from B John in Sweden.  He asked about the benefits of microgravity for disabled folks, then I read a longer email from him suggesting solutions for the microgravity, psychology, and radiation issues already existed and why was NASA not proposing and developing “these simple non-medical solutions to the problems you describe.”  Dr. Shelhamer responded to his email item by item. For the most part, he agreed with what B John was saying except that his information and perspective were limited and missing key components of the scenarios he was talking about.  Mark explained why our listener’s comments were way too simple and cited some scenarios to illustrate this.  It was a fascinating reply to what many of us believe are already effective countermeasures.  Unfortunately, while what many of us suggest is correct, what we suggest does not go far enough and does not contain the specifics and details of what is actually required to make a specific countermeasure work.  Otherwise, the countermeasures are far more complex than what B John asked about in his email which you will hear me read on the program.  I asked Mark about genetic modification and that took us to the subject of personalized countermeasures.  We talked about pioneering/space settlement, childbirth & children in the space environment, even gender differences for BELO HSF.  I asked about the differences from his perspective of doing HSF to the Moon, an asteroid, Mars, or Deimos.  There are differences, don’t miss his response.  As the program was ending, I asked if a commercial company without gov. funding could decide to do a BLEO mission without all the costs and safety concerns of NASA.  Mark said it might be possible though the costs of the missions and the technology needed would make it very hard for a commercial company to carry out.  He said a short cut bare bones mission might be achieved by a commercial company but the risks for the crew would be extreme.  If you were running a commercial company and funding such a mission, would you accept these risks, plus the risk the crew might not be able to do much or be effective once they got to their destination? As the commercial company CEO, would that be a good use of company money or would you dismiss what people like our guest today have to say about these issues.  Let me know your thoughts by posting them on the blog.

Please post comments/questions on TSS blog above. Mark can be reached through me or through his PPT presentation address.

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.

We welcomed back to the show Dr. Paul Spudis to discuss the NRC Human Spaceflight Study report recently released. You can download the report for free at http://www.nap.edu/openbook.php?record_id=18801.  Please note that this program was broadcast and recorded live on Wednesday, June 18, 2014.  It is being archived on Friday, 6-20-24 as there will be no live show on Friday due to the host travel schedule.  During the first segment of our 1 hour 36 minute program, Dr. Spudis first walked us through the NRC nearly 300 page study, hitting the highlights, raising questions, talking about what was good in the report and disappointing in it.  We talked about the rational for human spaceflight, for Mars, also the Moon.  We noted the absence of economic development in the report and this gave Dr. Spudis several openings to talk about his ideas for cislunar economic development.  Listeners asked lots of email questions ranging from budget issues, to SpaceX and rocket reusability.  Paul described much of what the study suggested as a form of “Apollo to Mars.”  Near the end of this segment we talked about public/private partnerships and learned that the Pathways study was only addressing public programs.  A listener asked Dr. Spudis what he thought the impact of the study might be and sitting on a shelf somewhere seemed a plausible answer.

In the second segment, Dr. Spudis focused on the response to the report and ways to actually develop a quality space program.  He talked about the need for a space transportation system, space infrastructure, and to use an incremental approach.  Robotics were discussed, we talked about the space media, and Dr. Spudis reminded us a few times that if there is no infrastructure, there can be no institutional use and capability.  We also compared the Apollo period and JFK’s goal for the Moon compared to now.  Its an interesting discussion, especially since we no longer have many of the skill sets we had back then.  The value of the Moon and commercial space came up & we talked about promoting the value to policy makers.  In supporting his incremental approach, Paul referenced a bit of US naval history.

Please post your comments/questions on TSS blog.  Check out Paul’s blog, http://www.spudislunarresources.com.  You can contact Dr. Spudis through his blog or me.

We welcomed Ed Wright back to the show to discuss Citizens in Space and the new U.S. Rocket Academy Lynx Cub Payload Carrier they developed with the Texas A&M Space Engineering Research Center.  For more information, visit http://www.citizensinspace.org.  During the first segment of our 1 hour 34 minute program, Ed talked about space settlement per his recent talk at ISDC 2014 in Los Angles.  After introducing us to the topic, he talked about how space settlement needs to evolve to a permanent base by starting smaller and boot strapping along the way.  He explained the process as he visualized it and outlined how such a process, including how both suborbital and orbital flights would lead to job creation, eventually job creation in space.  As part over his overall strategy, he includes the Maker Faire movement and contrasted Maker Faire to a typical space conference where Maker Faire draws thousands of people and a typical space conference draws a few hundred to maybe a thousand people.  We talked about the role to be played by ISS, military space, and the challenges presented by the human factors medical issues as well as other technical challenges.

In the second segment, Doug emailed asking about the ISDC reception Ed got regarding his talk at ISDC.  Also, Charles emailed in during both segments to suggest the Microlaunchers approach and to once again voice his doubt about suborbital tourism becoming a successful industry.  We also talked about the Citizens In Space New Space Research Platform which is ready for flight testing, the Lynx Cub Payload Carrier developed with the Texas A&M Space Engineering Research Center and XCOR.  The carrier will be used on 10 Lynx mission and made available to XCIR customers as ready to fly hardware or even as open-source hardware.  You can read about it at http://www.citizensinspace.org/2014/05/lynx-cub-payload-carrier-ready-for-flight-test and at http://www.citizensinspace.org/2014/05/lynx-cub-payload-platform-will-be-unveiled-at-makercon.  Ed then explained how Citizens In Space is broader than his earlier program, the original Teachers in Space program, and that now preference for being flown to space goes to those submitting science experiments for the upcoming suborbital flights using the Lynx Cub Payload Carrier.  He offered excellent closing comments.

We welcomed Frank Van Rensselear to the program to discuss Schafer Corp and various commercial space topics and issues.  Our program was an hour long so we had only one segment.  We started our discussion with by talking with our guest about his experience as an Apollo Flight Controller and he described his position as The Booster.  He shared some of his experiences with us, especially for Apollo 8 and Apollo 12 which was hit by lightening shortly after launch.  Frank was also on the job through Skylab and the ASTP.  Listen and enjoy the history.  We then jumped into his experiences in commercial space and his having developed over $300 million in new business when he was with the Harris Corporation.  Our guest was asked about the newly released NRC Pathways Human Spaceflight Study and he said he basically agreed with it in that we do not have enough money, we can’t do meaningful and inspiring projects, and overall he suggested this was demeaning to the country.  We talked for several minutes about tight budget issues for NASA and the way congress and the American people set priorities which do not seem to include human spaceflight.  I suggested this is a choice & asked how we get policy and budget pros within the system to make different choices in support of HSF. Frank was asked if Constellation had not been cancelled if we would be in a similar position today with our dependency on Russia and related issues.  He did not think so but listen to his full response.  We talked about the RD-180 engine and the likelihood that congress will appropriate funds to make a U.S. replacement engine.  This brought up the need for such an engine if we have Delta and soon will have Falcon 9 which still gives us two independent launchers for high value national security payloads.  Frank had lots to say on this subject, on SpaceX and ULA, along with the importance of these national security satellites and launches.  John in Tucson emailed him about SLS on which our guest also had much to say.  But as long as we are focused on tight budget issues, the program has been & will be disappointing. Again, you don’t want to miss all of his comments on this issue.  Military space was a discussion topic as was public opinion suggesting space is not that relevant any more. We talked about Inspiration Mars being able to inspire but we both doubted it would happen.  Tony called in to ask about reusability & why the space shuttle was compromised and reusability taken out. In the end, our guest suggested that reusability would be key to our space future.  Next, we talked about Schafer Corp and its activities.  We learned that they consult and work with several NewSpace companies and they are hiring but typically they go for experienced engineers, not fresh out college grads.  I asked Frank for his perspective on the recently announced Google purchase of Skybox Imaging for $500 million.  This too was a most interesting discussion you do not want to miss.  Other topics during our program included billionaire space investors, suborbital tourism, space settlement, and commercial space growth by sectors.  Here we talked markets, needed infrastructure and capital acquisition for lunar projects and the like.  Our guest talked about the need for government sponsored infrastructure in advance of lunar commercial projects and suggested only government was capable of footing the bill for the needed  infrastructure.  He said raising the actual capital was a challenge and that at this time, it would really be uphill for lunar ventures.  In his concluding remarks, he said he was bullish for commercial space and private space companies and that going commercial was a good thing as it has & will bring in fresh ideas & projects.  His final question was about 3D printing for space.

Please post your comments/questions on TSS blog.  You can reach our guest through the Schafer Corp website, http://www.schafercorp.com or me.

We welcomed James Pura and Aaron Oesterle to the program to discuss The Space Frontier Foundation’s Space Settlement Enabling Test (see http://spacefrontier.org/settlement-enabling-test).  During the first segment of our 90 minute program, James and Arron went over the history of how the Space Settlement Enabling Test got its start within the SFF.  We also learned that it is in response to public space programs, not private programs though parts of the test would be applicable to private ventures but applying it that way is not a purpose of the Foundation.  The SFF Board votes on the projects being applied to the test with the results being published on the SFF website (http://spacefrontier.org).  We learned that the test consists of 21 questions in seven categories with each question having a voting range of 1-5.  There is a score for the project being subjected to the test but there is no pass or fail.  For example, the Foundation applied the test to the now defunct Constellation program and its score was 36.5%.  Our guests explained in detail how the test worked and during this segment and part of the second segment, they went through the questions in each of the seven categories.  Listeners had many questions for them including how they planned on measuring the effectiveness of the test and the outcome.  Our guests talked about both the inside and outside means of using the test and getting the results out to the market, policy makers, etc.  One listener asked James & Aaron if the test was jumping the gun since space settlement is far off into the future.  Don’t miss the reply to this question offered by both our guests.  Doug called to talk about applying his Cis Lunar 1 project to the Space Settlement Enabling Test.  Prior to the end of the segment, our guests talked about the importance of insuring sustainability for space settlement and how that was reflected in the test.

In the second segment, we finished going through the balance of the test and then we opened up the discussion for questions.  In discussing the final categories, our guests brought up the issue and importance of space property rights, competition, and the need for a tax payer ROI on public space ventures.  We talked about what may contribute to a public sector ROI.  In the question segment, nuclear propulsion was brought up, our guests were asked if they had applied SLS to the test.  Each of our guests offer us important closing comments and take aways from our discussion.

We welcomed back to the program Joe Carroll to follow up on his May 2011 Space Show Classroom program on the same subject.  Our panel members included Dr. John Jurist and Dr. Jim Logan. All of us were part of the May 2011 program on this same topic.  During segment one of our 2 hour 10 minute webinar, Joe Carroll went over his background, interest, and experience in the subject dating back to 1981.  Joe discussed his recent work and updates including his concerns for the rotation rate, Coriolis effect & the absence of any substantial progress in the area.  He directed us to Slide 2 & the specific language used in the 201 US National Space Policy introduction.  Our guests talked about missed opportunities by NASA & others to do the essential research needed to confirm the gravity prescription for humans.  Our guests also talked about the amazing amount of unknowns regarding the effects of microgravity or Zero G on humans as we are a 1 G species.  The issue of space settlements came up & I asked our guests if we were jumping the gun pushing settlements when so much of the human factors work remains unresolved and even unknown.  Joe talked about two extremes in the approach to settlements.  He said one extreme was to simply prove issues by walking.  That is, just try it.  The other extreme was to do “endless research and studies,” a critique often mentioned by space advocates.  Jim pointed out that essentially knowing nothing about the Gravity Prescription despite 53 years of human spaceflight experience doesn’t rise to the definition of “endless research and studies.” Apollo was the walking theory for the most part.  Our guests then talked about NASA plans for an outpost as compared to a settlement, specifically for the Moon.  During this segment, we received several listener emails which the guests responded to.  During this time, Jim continued to state that it was essential that we know at least the basic outlines of the gravity prescription for humans for long duration interplanetary spaceflight.  Our guests talked about the ISS and the role it could play in supporting gravity research.  Joe continued to discuss more of his slides and our panel members had much to say about the discussion. Toni called at the end of the segment to ask about 1 RPM spin rate and mentioned that SpaceX said it wanted to go to Mars by 2020.  Here is the article Tony referenced:  http://www.dailymail.co.uk/sciencetech/article-2634046/Elon-Musk-says-SpaceX-making-progress-Mars-colony-2020-plans-sell-tickets-500-000.html.

In the second segment, we decided to hold the listener emails until the end of the broadcast to allow Joe time to finish his slides and state his conclusions.  We started off with Slides 6, 7 & 8.  Joe progressed to talk about the inflatable tunnel, some of the technical aspects including specs and diameters and why one was better than the others.  Joe continued taking us quickly through the slides but for those interested in the details, pay close attention to them or contact Joe as his email address is on his presentation material.  Joe spent some time this segment talking about doing Gemini-like tether experiments and he also referred us to Robert Walker’s work.  Robert is a Space Show guest from the UK who has done excellent work on the issue of partial gravity based on Joe’s work with tethers, etc.  Check out Robert’s paper at
http://www.science20.com/robert_inventor/crew_tether_spin_for_artificial_gravity_on_way_to_iss_stunning_new_videos_space_show_webinar_on_sunday-137070.  Don’t miss the links to the tether spin videos in his paper.  The subject of rocket reusability came up and again, Joe and our guests had much to say about this so don’t miss it.  Also in this segment, there was more focus on spin rates.  Joe took us through is conclusion slide which is Slide 20.  He talked about the difficulty in selling space as the next stuff and said one never launches with cutting edge hardware.  We then fielded second segment listener emails on a variety of topics, then we talked about people wanting to go to Mars with the just do it concept mentioned in the first segment.  Several Dr. Zubrin comments were used as illustrations along with SpaceX plans to do Mars by 2020.  All of our guests said there was a significant difference in a short trip to the Moon with Apollo where the decision was made to take the risk for a few days but that going beyond LEO for a long trip to Mars for example was a totally different thing altogether.  Jim used long duration sailing voyages as an example of how the issues for the crew once the long duration trips were started turned out to be very vastly different than for short, easy, turnaround ‘sortie’ voyages. Once transoceanic voyages were attempted it didn’t take Captains, crews or their respective patrons long to realize long duration voyages came with radical new levels of complexity and increased human risk.  We talked more about tethers as well.  Jim made the point that the average time spent on the Moon per Apollo lunar moonwalker was only 2.06 days, a woefully inadequate time to ascertain increased risk.  Joe also talked about the possible study & use of 0.06 G as explained in Slide 8.  I asked each guest for their concluding remarks, starting with Dr. Logan.  His take away was that it is critical to know the gravity prescription. Dr. Jurist was next saying there was no useless research and that gravity research may very well benefit us here on Earth in ways we can’t even imagine at this time.  Joe summarized his concluding thoughts per his last slide, talked about his possible plans to be more proactive with his work and suggested easy experiments that could be done with a Dragon and the spent first stage even on an ISS mission.

Please post your comments/questions on The Space Show blog above.  You can reach all of the guests through me but as stated earlier, Joe lists his email address on his presentation material.

We welcomed back Dr. Jeff Bell & was at his best for blunt talk, specifically the need for a winning rational for human spaceflight (HSF).  For those of you new to Dr. Bell, hold on tight for a ride that will likely be upsetting.  During the first segment of our 1 hour 58 minute program, Dr. Bell started with saying he was pessimistic over the future of human spaceflight.  In fact, this was an overriding theme throughout the full discussion.  He said it was more than just not properly telling the story either by NASA or space advocates.  He said there was no winning rational for the need or the urgency of HSF.  While he was pessimistic on HSF, he was just the opposite on science, robotic, & unmanned missions which he said were doing well & in a class of their own.  He also talked about the success of satellites & that part of the commercial industry.  Listeners challenged him during the show.  He got several emails regarding space settlement which Jeff addressed in terms of his perspective on HSF.  He also nixed the idea of leaving Earth as a safety valve for when Earth might be destroyed by an incoming NEO.  This led Jeff to talk about planetary defense.  Tony called with an idea to keep a Martian settlement from freezing at night, a point Jeff talked about re Mars settlements.  A listener asked about radiation & magnetic fields.  Jeff said the atmosphere was more of a screen for Earth, again in a discussion about lunar & Martian settlements.  Jeff talked about Orion & SLS, various ideas for Mars missions & the NASA asteroid mission.  I asked Jeff what he was positive about & he replied the Russian space program & SpaceX with Elon.  He then spoke about some of the Russian programs he follows.  He was asked about space tourism & suborbital flights, then he spoke about SpaceShip2 problems, hybrid engine issues, Richard Branson & more.

In the second segment, he had more to say re SpaceShip2 & Branson.  Next, he was asked about space debris cleanup ideas being skeptical of them.  He was also skeptical of propellant depots.  He spoke about small boosters costing much more than using one large booster.  Pooley called in to support everything Jeff was talking about.  Dr. Bell was asked about Dream Chaser.  In general, Jeff was very critical of lifting bodies & their CG problems.  Listeners asked for his assessment of Inspiration Mars & Mars One which was not positive.  In his closing comments, he said HSF was probably mature & needed radical new technologies to make it cheaper & feasible.  I told him he should come back on the show, invite only callers & emails suggesting radically new & different technologies & he could assess the ideas.  Dr. Bell agreed to do that so watch the newsletter for this upcoming program.

We welcomed Dr. Tom Matula back to The Space Show for a 1 hour 46 minute discussion about Tom’s concept for space settlements known as astrosettlements.  His Power Point presentation given at the ISDC 2013 has been uploaded to The Space Show blog for your review.  In the first segment of today’s program, I started out asking about one of Tom’s previous theories, the Space Development Bank.  From there, we jumped to astrosettlements which Tom believes will be market driven so we discussed some of the market factors that could drive these settlements.  Astrosettlements are orbital and would be designed for 500 to 1,000 inhabitants.  He listed three characteristics for the astrosettlements and we discussed each one.  The three included the need to be autonomous, mobile, and expandable.  Doug called from S. California to talk about and clarify market demand.  This led Tom to discuss the potential of the SpaceX Dragon Lab.  He also talked about suborbital with his understanding that the killer part of suborbital would not be space tourism but instead atmospheric research.  I asked Tom for timelines for the astrosettlements and he said 2-3 decades. This sparked further discussion.  When I asked for the starting point to develop the astrosettlements, Tom said we would need to develop virtual world models.  This resulted in a rather comprehensive discussion of modeling in the virtual world with Charles calling in to disagree across the board with our guest.

In the second segment, I read a lengthy email from Carl in San Antonio that deal the lunar development, the Moon Treaty, Common Heritage of Mankind and benefit sharing issues.  Don’t miss this discussion. Paul Turner both emailed in and called regarding how to profitably develop real estate in orbit, and why it is financially sustainable.  Paul has a book coming out on this topic so we will hear more about this later on.  More timeline questions came up regarding astrosettlements and the potential early market drivers which might include intellectual property, early materials manufacturing, and raw materials.
