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

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

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

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

Please post comments/questions on The Space Show blog.  You can reach the panel members through me.

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

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

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

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

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

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

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

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

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

We welcomed back to the show Dr. Jason Cassibry from the University of Alabama Huntsville to discuss nuclear propulsion of all kinds.  In our initial segment of this 1 hour 30 minute discussion, I first asked Dr. Cassibry about a fusion drive project as reported at www.youtube.com/watch?v=r-jlv1x3ov4.  Dr. Cassibry spoke about the work going on at the University of Washington which was mentioned in the fusion drive video above.  We then talked about transit times to and from Mars and the differences with chemical propulsion, nuclear thermal, and then fusion.  During this discussion, Jason also described the differences in nuclear thermal and nuclear electric propulsion.  A related issue we discussed dealt with the nuclear regulatory environment.  We talked about the nuclear climate, protests, and how best to overcome such protests.  Doug called asking about timelines and said it was moving at such a slow pace, for his projects that he thinks about, he dismisses nuclear propulsion, instead opting for analysis and mission planning using chemical rockets though many are not much further along than a Power Point at this point in time.  Doug also thought it might be easier to do nuclear propulsion by partnering with Russia as they might be easier on the regulatory environment than the U.S.  Our caller asked about ion propulsion and thrusters as well as thermal protection needs.

In the second segment, Jerry emailed about nuclear propulsion in other countries plus more about possible consumer protests.  Ben asked if we could substantially improve chemical rockets and I inquired as to why the recent nuclear program Prometheus was killed.  VASIMIR was next brought up for discussion.  I asked Jason about nuclear accidents in space or on Mars and would they be as destructive as nuclear reactor accidents here on Earth.  Jason provided a most interesting answer saying he thought nuclear reactors in space would be accident proof!  Christine in Dallas suggested we need a better story for more support for nuclear propulsion.  Don’t miss the reply offered by Dr. Cassibry. Near the end of our discussion, I asked our guest about suborbital propulsion.

We welcomed Dr. Wendell Mendell back to the show for this two hour discussion (no break) about his 50 years at NASA JSC, lunar bases, commercial space, return to the Moon, the value of the Moon, our space program, space advocacy, commercial space, and lots more.  Dr. Mendell came to work at JSC in 1963 &will be retiring at the end of this year, culminating 50 years at JSC.  During our discussion, Dr. Mendell used lots of stories from his NASA and lunar base work experience to illustrate issues with space policy, NASA, our Congress, and space advocacy, & advanced technology.  Listeners had lots of specific questions for Wendell about lunar bases, water on the Moon and its commercial exploitation, commercial lunar programs, and NASA having a lunar program which Dr. Mendell said it did not.  Dr. Mendell spoke to some of the NASA organizational issues, congressional micromanagement issues and problems, and the nation’s overall economic problems as a reason for not doing this or that in space.  He cited such economic problems as a rational excuse for not doing something meaningful in space in almost every year of his 50 years of NASA experience. The same for threatened, proposed, or even real NASA budget cuts.  Later in the segment when caller Doug called in with his lunar water and development ideas, Dr. Mendell pointed to conflicting LCROSS analysis as to water being on the Moon. Russian instruments do not say the same thing as the Los Alamos instruments and he said this was & still is a hotly debated topic in the lunar community.  As Doug continued talking about his plan, Dr. Mendell backed him up, took him step by step through the process of accomplishing his many goals. This turned out to be a very valuable instructional discussion that all of us can and should benefit from.  Make sure you hear how Wendell breaks down Doug’s points to show the complexities and challenges of each incremental step in what Doug was proposing.  Our guest even showed Doug where some of his steps needed commercial technogly which does not exist! Doug’s rocket of choice is the Falcon Heavy, a rocket which does not yet exist, nor does it have real numbers behind it.  Wendell used this discussion to distinguish true believers from investor and commercial analysts.  He then said when the believer is also able to bring his own money to the venture, things can get done and he cited SpaceX as an example.  Later Doug asked by email if NASA could help private companies develop cislunar transportation as they have helped private companies provide launch services to LEO/GEO. The simple answer was yes but make sure you hear Dr. Mendell’s complete answer to this question.  Another issue discussed was the needed timeline to do a human Moon mission. Wendell described the times of Apollo as compared to the times of NASA today.  We talked about the importance of a better and different NASA and RTM story and again, Dr. Mendell illustrated his points with stories from his past experience.  Spanning 50 years of history and experience was not easy to do in even a two hour Space Show program. As you listen to the program, you will hear many more subjects, stories, and issues discussed than stated in this summary.  In the end, I believe NASA, our nation, and the effort to develop space has been served incredibly well by Dr. Wendell Mendell and his creativity, his drive, his analysis, his commitment, and his work will be genuinely missed by all.  The Space Show wishes Wendell all the best for his coming retirement, gives him a hearty THANK YOU for his service, and we will remain in contact with him and hope to have him back with us at a future time.
