We welcomed back Robert Walker from the UK to discuss artificial gravity with us given our recent Space Show programs on the subject.  There was an audio issue with this program so listen carefully so you don’t miss anything.  During the first segment of our 90 minute program, Robert went over some of the basics such as the Coriolis effect, the gravity gradient, tethers, centrifuges, the vestibular effect, and more.  He also went over linear acceleration, spin rates, Russian experiments, issues facing space tourists, and spinning a Dragon capsule.  Robert has written many articles on artificial gravity which can be found at www.science20.com/space.  One such article was discussed yesterday. See  www.science20.com/robert_inventor/blog/ingeious_idea_soyuz_crew_tether_spin_way_iss_artificial_gravity_almost_no_extra_fuel-131278.  Also, check out www.science20.com/print/131279; www.science20.com/print/131278 & www.science20.com/print/129424.

In our second segment, Robert talked about both Inspiration Mars and Mars One as it relates to spinning to create artificial gravity, the number of revolutions per minute, simulate programs, and his favorite, a 2-3 year precursor mission at Earth L2.  He wants the mission designed to be a comprehensive test bed for artificial gravity.  Later in the segment while discussing Mars, he suggested we orbit Mars and not land on the planet.  Listen to his reasoning for this type of human Mars mission.  For one thing, he said its much safer to be in orbit.  We then focused on the possibility of microbial life on Mars, we talked about the Viking Labeled Release experiments.  Robert was asked a question about the sleeping centrifuge (you sleep horizontal as one does on Earth).  Partial gravity was discussed as well.  Robert said many times that we must find out what is going on with Mars. He mentioned the Phoenix mission which Mars One is planning to copy to some degree with its robotic mission to Mars in 2018.

We welcomed back Dr. John Jurist for this two hour discussion on all aspects of artificial gravity.  Note that Dr. Jurist prepared presentation material for this program which you will find on the archived blog entry for this discussion.  Also, I recommend you read the excellent article by our UK guest, inventor, & friend, Robert Walker, “Can Spinning Habs Solve the Zero g Health Issues?  Can Humans Live in Mars or Lunar g? Why Nobody Knows.” (see www.science20.com/print/129424).  During our first segment, Dr. Jurist introduced us to the basics of artificial gravity including the Coriolis effect, the gravity gradient & the info needed from in-space artificial gravity R&D.  Several studies including one by UC Irvine were mentioned, plus other bed rest studies.  He also talked about the Wyle Centrifuge studies which used a short arm for experimentation.  Our attention turned to the presentation material on TSS blog titled “Artificial Gravity Comments–JmJurist.”  Dr. Jurist took us through the tables & charts on his two page document.  He was asked about gender & age differences with gravity as well as small rodent/mammal ISS experiments now or in the future.  Our first caller was John from Ft. Worth who clarified some of his comments from the last Open Lines show plus he talked about the hardware, infrastructure, & engineering issues for in-space experiments.  We talked about the use of tethers & the relationship with microgravity & radiation issues.  With our caller still with us, Jenna emailed asking if either Mars One or Inspiration Mars would provide the needed research that never seems to be done by NASA or others.

In the second segment, Doug from S. California called.  He talked about his T frame tetherball type structure concept as an interim artificial gravity tool but said it was not a long term solution.  He also inquired about tethers, then he wanted to know about the mass of possible tether cables as well as potential materials that could be used for in-space tethers.  Doug then described a reference mission using a long arm centrifuge for the surface of the Moon.  Doug described a very good concept and Dr. Jurist had much to say about it.  We had quite the discussion on possible implementation strategies and the roadmap from theory to operations given our current policy & economic environment, plus the track record on other large projects that never made it.  With Doug on the phone, Ft. Worth John emailed to inquire about stability issues and tidal forces on the tether.  Both Dr. Jurist & Doug made a pass at providing John an answer to his question.  In his closing statement, our guest went over some basic advantages with a tether, the problems of the gravity gradient & the fact that the issues for colonization were very different than for experiments or a reference mission.

Please post your comments/questions on TSS blog above.  If you want to reach Dr. Jurist or our callers, do so through me.

Guests:  Classroom:  Dr. David Livingston, Joe Carroll, Dr. John Jurist, Dr. Jim Logan.  Topics:  Manned artificial gravity research station in LEO.  Please note that this program originally aired as a Space Show Classroom program May 3, 2011.  This replay is being brought to you today as a result of the interest expressed in the subject during the Open Lines program of Feb. 2, 2014.  As this is a Golden Oldie replay, there is no live participation with this program.  If you have questions or comments for the co-hosts or Mr. Carroll, post them on The Space Show blog for this entry.  In addition, when the original Classroom program first aired, Mr. Carroll provided presentation material. You can see this material by going to http://spaceshowclassroom.wordpress.com/2011/05/01/lesson-three-presentation-material-5-3-11 and clicking on the two items available for review and download.  Also, the summary below is the unedited summary from the May 3, 2011 Classroom program which is posted both on The Space Show website archives for that date as well as on The Space Show Classroom archives for that date (http://spaceshowclassroom.wordpress.com).

This two hour plus Classroom program was continuous without a break.  For this program, refer to the Power Point presentation by Joe, “Design Concepts for a Manned Artificial Gravity Research Facility.”  Mr. Carroll took us through this presentation slide by slide, plus he responded to listener and co-host questions throughout the program.  You can find this presentation plus his longer IAC Conference paper on The Space Show Classroom blog under Presentation Materials for our Classroom program for May 3, 2011.  Rather than writing a summary of this program, let me say that Mr. Carroll has given considerable thought to the engineering and human factors/human physiology issues regarding an artificial gravity research station in LEO.  Listener questions addressed technical issues relating to spin, center of mass/gravity, hits by orbital debris items and more.  Throughout this Classroom discussion, Joe took us into the technology, operations, and why’s regarding his artificial gravity research station.  Many issues were discussed including but not limited to Mars & lunar gravity, .06 G, spin rates, the Coriolis effect, the Gemini experiments, a Moon/Mars Dumbbell Concept, Airbeam tunnels, radial structure lengths, and much more.  Toward the end of the program, we discussed the economics, costs, and who might pay for and deploy such a station.  You will hear Joe talk about the present economic, cost, and R&D uncertainties for such a project, but you will also hear him talk about the commercial potentials, who should be given “free” access to the research station and why, the use of it with Space X as well as Bigelow, and why not doing it as a NASA project makes sense though he advocated NASA as a customer.  At the very end, I asked Joe about building some small models to help those of us who are not engineers in understanding and even visualizing his concept.  He liked that idea, talked about larger models of the size of a Boeing 737 cabin (he used this cabin size throughout his discussion and presentation), and possibly locating it at a company such as Space X.  As we concluded our discussion, all of us said that after 50 years of human spaceflight, to not be able to answer any of the questions regarding the issues discussed in this program was criminal. Furthermore, as you will hear Dr. Logan and the others say, you can determine the credibility of a human space program by the speed and determination of the commitment to understanding the necessary gravity needs for people, plants, and animals in space.  If there is no commitment to understanding these issues, the program is more likely a rhetoric only program.

Welcome to this two hour one minute Open Lines discussion on what turned out to be mostly about artificial gravity.  While there were actually two breaks in this program, since the topic was the same throughout the full show, I am archiving this as a single segment summary.  We started the program by my making announcements, then reading parts of an article that recently appeared in the Turlock Journal (www.turlockjournal.com/section/26/article/23874) that talked about the green efforts by actor Leonardo DiCaprio but also pointing out his having arranged to be an early passenger onboard SpaceShip2.  The author of the article, Dennis Wyatt, then pointed out the hypocracy of Mr. DiCaprio by examining the carbon footprint of SpaceShip2 & comparing it to cars & other things, pointing out the enormous consumption and carbon footprint that will be unloaded on Earth by Mr. DiCaprio’s flight.  I read parts of the article to point out the hypocracy among those that preach to us to do as they say yet they seldom if ever walk their own talk.  I also mentioned articles in the informative menu of The Black Bear Diner Gazette from their Emeryville, CA menu, one of which was an old news article saying that NASA Administrator Thomas Paine predicted & had a goal of doing a HSF mission to Mars by 1981-82.  Some of the callers for today’s discussion did offer comments on both the DiCaprio article as well as wondering if we could have gone to and from Mars with astronauts back in 1981-82.  However, by far, the topic of the day was artificial gravity, a topic which really surprised me.  The callers and those sending emails wanted to talk about artificial gravity, their understanding of it, how to achieve it, their analysis of it, and more.  The callers talked 2 RMs, 3 RPMs, 4 RPMs, we talked about some of the comments by the life scientists on this subject on previous shows, much of which was discarded by the callers who had a focus on engineering and physics and their own perspectives.  We also talked about the difference between partial gravity & full 1 g artificial gravity.  I mentioned that many were unsure that 1 g of artificial gravity would be the same as 1 g here on Earth but that was quickly discarded by all callers and those sending in emails.  Our callers also talked about experiments that should take place using free flyers adjacent to the ISS to study some of the artificial gravity questions in preparation for long duration human spaceflight.  Because of the unexpected interest in artificial gravity, I have decided to arrange for updated programming on the subject with “experts” representing aerospace medicine, life scientists, engineers that would be designing space based centrifuges, and more.  I will be announcing these programs as they are scheduled & they will appear in the weekly newsletters.

Please post your comments/questions for this show on TSS blog above.  You can reach any of the callers to this program by sending your email through me at drspace@thespaceshow.com.

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm.  We welcomed both Dr. Michael Schmidt and Dr. Thomas Goodwin to this 1 hour 28 minute program to discuss their findings represented in their recent published & reviewed paper, “Personalized medicine in human space flight: using Omics based analysis to develop individualized countermeasures that enhance astronaut safety and performance.” I’ve posted this paper on The Space Show blog and I urge you to read it as I believe it will the way of the future for human spaceflight astronaut safety and enhancement.

We started our discussion with Dr. Schmidt stating the problem(s) with astronauts in the extreme space environment, longer mission duration stress, plus other factors.  Dr. Schmidt followed by Dr. Goodwin then explained and discussed personalized medicine in human space flight and the use of Omics analysis.  Their work was also applied to the emerging space tourism industry as well as for suborbital missions.  Regarding the suborbital flights, the interest seems to be more with the pilots who will be making many trips to space rather than the participant who will likely be doing it only once.  Our guests put forth the reasoning for personalized space flight medicine, we talked about the capabilities to do this screening and the studies today, what will be near term and what we can expect over the longer term as technologies develop.  Listeners asked about conventional mitigation strategies such as shielding, exercise, etc.  Our guests pointed out that they were not talking about eliminating the usual mitigation strategies but tailoring needs to an individual’s DNA and genetic makeup since  individual astronauts may have genetic and DNA differences that will respond better to a customized mitigation.  We talked about varying degrees of DNA stability & unstable DNA.  Much was said about the effects of RX medications and drug profiles.

In our second segment, we talked more about the suborbital flights and the interest in the pilots due to their repeat flights.  We talked about targeted RX medications for an individual, how medications are metabolized & how that might actually differ in the astronauts leading to customization.  Doug asked about a type of primate ISS experiment regarding fractionalized gravity.  Listeners also wanted to know about adding mass and cost to a mission due to personalized space flight medicine which as you will hear, was not the case.  In the concluding comments, our guests pointed out that personalized space flight medicine was going to be the future of human space flight.  Personalized and target DNA and genetic medicine is already starting to happen here on Earth so its extension to space is only natural.

We welcomed back Dr. Bill Rowe to the program to discuss his important discovery regarding four Moon Walking astronauts.  In our first segment of this two hour discussion, Bill explained his latest research findings& what his conclusions mean for human spaceflight.  To find out more about Dr. Rowe’s research, to read his papers, & to learn more about telomeres, oxidative stress, & astronaut cardiac issues, visit his website www.femsinspace.com.  In this segment, Bill talked about damaging the lining of the endothelium, too much or too little adrenalin & magnesium, & the four Moon Walking astronaut abnormal stress tests.  Our discussion then turned to the Inspiration Mars flyby mission which our guest said was not survivable.  Bill went over his reasons for his conclusion regarding this proposed 501 day mission& talked about 1G being the law & what that means for our bodies to be in less than a 1G environment.  Bill then talked about telomeres & possible damage for the round trip Mars mission, plus he talked about the lack of an effective space exercise protocol as well as problems with prescription medications in space, including the need to deliver medicines subcutaneously but there is no such subcutaneous drug delivery system.  Several times during our discussion, Bill said we might not be ready for humans to Mars for a long time, he kept asking what the rush was to go so quickly.  He commented on the Buzz Aldrin cycler plan which he thought was doable 22 plus years from now assuming our research advanced in the time leading up to such a mission.  Bill talked about radiation, including the recent data NASA released from the RAD instrument on MSL in space & on the Martian surface.  Eric sent in a clarification comment about the possible death of an Inspiration Mars crew member& he asked Bill about his exercise statements which he said did not seem to be in agreement with statements made by other aerospace medicine professionals.  Dr. Dear emailed in a question from the UK about Bill’s thinking that there will be no survival chance re Inspiration Mars.  He compared that to the record in space held by the Soviet Cosmonaut on Mir, citing that record as reason to think that the crew could survive the 501 day Mars trip which would only be about 64 fewer days in space than the Mars flyby mission.

In our second segment, we talked about possible lessons learned from the Inspiration Mars flight & Dr. Rowe talked more about the Buzz Aldrin Mars plan.  Bill then moved to the issue of females being better suited for spaceflight than men.  He had much to say on this subject plus he has several papers addressing the subject on his website.  Hint: Iron toxicity is a big issue.  Dust issues were discussed in this segment& Bill talked again about his submarine analogy on oxidative stress from his website (www.femsinspace.com/Oxidative_stress.htm).  When asked for some recommendations, Bill talked about the need for centrifuge studies & suggested rat studies with an on orbit centrifuge.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information.

We welcomed Dr. Claude Piantadosi to the program to discuss his new book, “Mankind Beyond Earth: The History, Science, and Future of Human Space Exploration.”  If you buy the book using this Amazon URL, www.amazon.com/Claude-A.-Piantadosi/e/B001IU0QRS/ref=onegiantlea20, Amazon will contribute to The Space Show/OGLF.  During our first segment of this two hour discussion, we compared the space environment to the undersea environment, and live support and environmental issues with a nuclear submarine as opposed to what we have available today for space flight.  Our guest talked about the advantages of human spaceflight (HSF) over robotic missions, plus the contributions to advancing technology, science & our understanding of our own environment derived from HSF.  Radiation & microgravity issues were mentioned and listeners started asking detailed questions pertaining HSF and Mars missions.  Much of this segment focused the two planned Mars missions and the human factors challenges.  In addition to a comprehensive analysis from the medical perspective, listeners also pointed out that Inspire Mars would likely have indirect if not direct public money supporting the mission.  Most were less supportive of the mission if it included public money, direct or indirect.  Dr. Piantadosi talked about radiation & microgravity unknowns and variables. He also talked about our current time line for meeting human factors & life support challenges over the near term which was not good.

In our second segment, we talked about affordable space & how to achieve it. Heavy lift and SLS came up as did fuel depots and reusability.  A listener asked about older people being more radiation resistant or tolerant. Long duration spaceflight mental issues came up and our guest talked about them in the context of crew selection and training.  Procreation in space was discussed as was the mass needed for water radiation shielding.  Our guest suggested that since the shuttle retirement, our space program had lost its focus.  He said there were no plans to get us the next level of information needed for travel beyond the Van Allen Belts.  He also talked about a lunar first program to learn and get the needed information to go to an asteroid or Mars, suggesting this might be a 15-20 year research program.  In the context of lengthy missions, our guest addressed sequestration and the need for international projects and financing. When asked if the recently announced private deep space missions had an edge over public mission, he did not think so.  Don’t miss what our guest said about this.  In closing, he urged us to engage in critical reading and critical thinking about problems.  Space is essential & we need to move forward with it using a good development & exploration plan.

Guest:  Dr. William (Bill) Rowe.  Topics:  Apollo astronauts cardiac & medical issues. Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://thespaceshow.wordpress.com.  Comments and questions should be relevant to the specific Space Show program.

     We welcomed Dr. Rowe back to the program to discuss his latest findings regarding four Apollo astronauts, lunar dust, microgravity, and cardiac conditions.  His work is presented on his website so do check it out, www.femsinspace.com.  Dr. Rowe’s latest findings came from his research using the Freedom of Information Act to get medical data from NASA after the recent passing of Neil Armstrong.  During our first segment, Bill explained what he found, what specific blood pressure and other information strongly suggests, and his comparison of the Armstrong data with that of several other Apollo astronauts per available data.  He also brought our attention to the problem independent researchers have in getting Apollo information and medical stats from NASA.  Bill used stress test blood pressure numbers and other medical information from the astronauts in question to illustrate his points and to back up his conclusions.  Most of our first segment was devoted to Dr. Rowe putting forth the information and his conclusions.  Bill took several email questions and listener calls, often wanting more information than he could provide because the reality is that there is an absence of additional information or relevant studies suggested.  One listener was asked if the ISS astronauts evidenced similar cardiac problems. Dr. Rowe was unable to answer that question due to the absence of information.

     In the second segment of this 2 hour 20 minute program, Dr. Rowe connected problems of lunar dust with urban pollution, suggesting microgravity studies that would benefit millions on Earth given how widespread the problem of urban pollution is on the planet.  One of the studies he proposed would use 30 female rats subjects to different calcium/magnesium rations on the ISS for six months.  Bill spent time in this segment explaining the importance of the calcium/magnesium ratio and what this means in space and for us back here on Earth, hence the rat study.  Dr. Rowe also talked about the difficulty of having a quality exercise RX for microgravity.  A listener asked about studies related to the Mt. St. Helens eruption several years ago re dust exposure.  Near the end of our discussion, Bill talked about their being no hurry to go to Mars, suggested many of the near term human spaceflight missions such as one way trips to Mars won’t happen for a long time because the human issues will not be resolved in the near term.  He also advocated the Moon first.  We talked about artificial gravity and I mentioned what other human factor gusts have said on air in that artificial gravity may not be the same as 1g here on Earth and may prove to not be a solution. Listeners did not like hearing that as they kept saying there would be an engineering solution to the microgravity issues.  Listener disagreements about artificial gravity not being the same as earth gravity continued long after the program ended.

    If you have comments/questions, please post them on The Space Show blog above.  You can contact Dr. Rowe through his website or through me.

We welcomed back Dr. Vadim Rygalov and for the first time UND SpSt graduate student Annie Wargetz to discuss her exceptional research regarding dietary & nutritional requirements for deep space mission astronauts.  Using Earth models such as submarines, extreme habitats, historical explorations, the Antarctica habitats, plus the ISS, our two guests shined an important light on a seldom discussed set of issues regarding astronaut nutritional challenges for deep space missions.  In the first segment of this two hour discussion, Dr. Rygalov introduced the subject to us & then he introduced us to Ms. Wargetz to discuss her work, research, & findings.  Many topics & issues were covered in this segment ranging from a broad discussion about extreme historical exploration missions, Earth habitats, submarines, the ISS, & more.  We learned what is known about deep space nutrition & astronaut food, eating, & caloric issues.  Annie talked about what we have learned from the different terrestrial models referenced in our discussion, plus many other issues presenting challenges such as food preparation, the lack of anything fresh, the lack of color in food, & the use of processed & chemical foods as is the standard for today.  She also talked about plans to mitigate these challenges on deep space mission flights. Bringing fresh vegetables, seeds, even small animals on a mission are plausible & were addressed.  One caller asked for a definition of a closed life support system.  Both our guests went into detail about this, including partially closed systems, bioregenetive systems, physical/chemical systems, & hybrids.  Vadim brought us current with our existing technology & what is likely to be available in the near term.  This is a comprehensive discussion pertaining to deep space environmental systems.

We started the second segment with our guests answering a question from the firsts segment about married couples in space.  Don’t miss their response & what Vadim said was his choice for the first crew for a deep space mission & why.  Mars 500 & Biosphere 2 were mentioned in their response.  Two other issues that were discussed were transit times to Mars with the faster travel time mitigating some of the human factor challenges including nutritional issues.  Also, it was clearly stated that to take on board the right type of nutrition, fresh items, seeds, perhaps small animals like chickens, a heavy lift launcher such as SLS was needed as the nutritional/food items will consume payload on the mission.  Vadim said heavy lift was needed to carry out the mission in one launch given the need for substantive payload dedicated to food/nutrition & astronaut well being.  Gender differences were discussed which is why Vadim suggested an all male first crew.  Other questions were asked about artificial gravity, developing & using a nutritional pill for space missions, issues about why astronauts don’t eat much on the ISS & more.

Guest:  Walter Cunningham.  Topics:  An inside view of the American space program from Apollo to today.  You are invited to comment, ask questions, & discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, & any discussion must be relevant & applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright.  We welcomed Walt Cunningham to discuss our space program from Apollo through today’s developing commercial space industry.  For more information, visit his website, www.waltercuningham.com.  You can buy “The All-American Boys: An Insider’s Look At The U.S. Space Program” from Amazon & they will make a contribution to The Space Show/OGLF if you use this URL: www.amazon.com/All-American-Boys-Walter-Cunningham/dp/1876963247/ref=onegiantlea20.  I started the discussion by asking Walt about his perspective on Apollo 7 today, 44 years later.  Walt had some interesting things to say about perspective, especially over the past 10-20 years as compared to when he actually carried out the mission.  A few times during our discussion, questions came up about the so called “mutiny” with the crew & NASA ground control so listen to how Walt described what was mostly a non-event despite media & blog reports to the contrary.  He did talk about Wally Schirra, his head cold & the Actifed commercials, but there was far more to the mission & to the significance of Apollo 7.  Dr. Jurist asked about the ride on a Saturn 1B, professors & experiences while both were at UCLA.  We discussed risk regarding his ride on the Saturn 1B. Walt had much to say about risk during the Apollo era as compared to now.  We extrapolated from this discussion to Columbia’s foam issues. We talked about commercial space.  Walt suggested that today’s commercial space efforts were not purely commercial given government funding & missions. He also said that retiring the shuttle when we did was a big mistake.  He then took us through a cost analysis process to illustrate that space is & always will be costly.  At the end of the first segment, one way trips to Mars & reality TV show funding were mentioned.

In the second segment, Terry called with questions about Von Braun. Walt had high praise & much to say about Von Braun & his experiences with him.  Commercial space came up again & I asked him about asteroid mining.  He did not think it would be a good investment & talked about the need to pay attention to the laws of physics.  We talked about He3 on the Moon, fusion energy possibilities & more.  I read an email from a London listener asking about the Apollo rocket & mission sounds on Apollo 7.  We talked some more about the problems on board Apollo 7, this time regarding Wally & the TV broadcast delay & the wearing of the newly designed helmets during reentry.  Walt talked about climate change & global warming, urging people to do their own research & examine the data rather than believing what people had to say regardless of their position.  John in Atlanta called in about global warming & said that there was no practical mitigation strategy. Our guest shared what he perceived to be the true motivation of global warming extremists.  John also talked about having built a next gen space shuttle from the old space shuttle to avoid retiring it or having to build an entirely new & very costly program.  Walt supported that idea but history proved otherwise.  Toward the end we discussed the pros & cons of international cooperation & competition, Ares 1 as a safe rocket for HSF, & the cost of the ISS being more due to international cooperation.  Our final topic was risk versus reckless behavior & the difference between the two.
