We welcomed Dr. Bryn Laubscher back to the program for our 2 hour 22 minute discussion about carbon nanotubes and the Space Elevator.  During our first segment, Dr. Laubscher talked about carbon nanotubes, the manufacturing process, how to move the process and technology forward, end uses for the product, possible timelines for advancement and the current day use of Chemical Vapor Deposition (CVD) in the process.  Bryan talked about the need to find a better process for making carbon nanotubes than CVD.  Later is this segment, Dr. Laubscher was asked about the potential relationship to space other than with the space elevator.  This was an interesting discussion , don’t miss it.

In our second segment, Bryan talked about how hard and challenging the space elevator was and later in the segment, due to a call from Pooley, we went through many of the top challenges faced by the elevator with a status report on each one.  As this segment was opening, I did ask Bryan for a time line for space elevator advancement.  Our guest suggested that at some point, there would be significant demand for the elevator.  Next, we talked about the upcoming International Space Elevator 2014 Conference to be held at the Museum of Flight in Seattle, August 22-24, 2014.  For conference info, visit http://www.spaceelevatorconference.org. John from Ft. Worth called to talk about materials, composites and much more. We also talked about the strength needed for the elevator ribbon and John asked about SSTO.  Blaze emailed us about nuclear waste and Bryan had an interesting take on it. This was another valuable discussion, don’t miss it.  Dr. Laubscher talked about ribbon length, characteristics, strength needed, and its location in space, plus the counter weights it would need.  Adrian emailed several questions to us about the ribbon breaking and related issues.  He also asked our guest radiation issues.  Doug emailed about ways to climb up and down the ribbon.  Some of the other issues that came up were wind, lightening, ribbon oscillation, space debris, policy & regulatory issues.  As our program was ending, Bryan offered us words of wisdom and said his company website was http://www.odysseustech.com.  In addition, Dr. Peter Swan emailed us about his paper on the elevator which you can download and read at  http://www.virginiaedition.com/media/spaceelevators.pdf.

We welcomed back Dr. Clay Moltz to the show to discuss his new book “Crowded Orbits: Conflict and Cooperation in Space.”  Please remember to buy this book through the OGLF/The Space Show Amazon portal so Amazon will contribute to The Space Show.  Our Amazon instructions are in every archive summary and on each Space Show blog entry.  During the first segment of our 90 minute discussion, Dr. Moltz told us why he wrote the book which was to address orbital crowding, possible conflict in space and to bring these issues and others to the attention of the general public as space impacts everyone everyday.  A major topic for our discussion was space debris.  Using this field as an example, Dr. Moltz  made a very strong case for rules of the road, space traffic control issues, and responsible behavior by both governments and the private sector.  We talked about entrepreneurs and private groups resisting a more regulated environment and he made the case for the need for cooperation to avoid conflicts.  Early in his book, he outlined three significant points of view regarding the debate over space policy, ranging from conflict & the military use of space was inevitable so prepare for it to avoiding problems by piecemeal global engagement to increasing the use of international space projects through international governance.  Dr. Moltz received many email questions challenging a regulated environment and the need for more controls on space businesses and operations.  We talked about the cubesat technology and growth of the industry, the lack of registration, & as the industry grows, possible crowding problems.  We also discussed the U.N. treaties that seem to cover what we were talking about so why the need for more agreements & regulations?

In our second segment, we continued our human spaceflight discussion from the end of the first segment, plus we looked at space in other countries.  We mostly focused on China, India, Iran, and North Korea among others.  We talked about large scale industries that may develop over time such as SSP.  GPS was an example, then a listener asked about cyberwarfare & the impact on space policy.  Toward the end of the program, I asked about space interest among students at the Naval Postgraduate School. Students are very interested space and the subjects discussed in Clay’s book and on today’s show.

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. Alice Gorman to the show for this 1 hour 38 minute fascinating space archaeology discussion.  During our first segment, Dr. Gorman explained space archaeology, talked about space debris, cultural preservation, and much more.  We talked about archaeological techniques used here on Earth and how they can be applied to space archaeology.  We also talked about the fact that most space artifacts are in space so what we often find in museums are replicas or simulated items which are not the same and have a different meaning for the archaeologist.  Dr. Gorman then talked about the possibility of artifacts from other cultures or even extraterrestrial life and questioned if we could even recognize what we were looking at or working with since it might be radically different from what we know and work with on Earth.  Listener Jonny emailed in to ask what would happen if China went to an lunar Apollo landing site and took some of the items left on the Moon back to be displayed in a Chinese museum.  Dr. Gorman did not think that likely, spoke about the Outer Space Treaty and that items are always owned by the launching company, and the NASA heritage sites guidelines they have proposed. Several questions came in regarding growth in the private, commercial, & entrepreneurial segments of the space community and how cultural and heritage protection might work with these nongovernment entities.  This led to an interesting discussion about company behavior, culture, early planning, awareness, and even benefit sharing.  We had a fun discussion about advertising in space for the ad to be seen back on Earth and we talked about how many of us hold the night sky sacred and do not want it spoiled.

In the second segment, Angela asked Alice when space archaeology would come into its own.  Alice replied that it already had “arrived” and cited many examples proving this.  Kimberly emailed in about the usefulness for archaeological purposes of space settlement garbage. Mars One was the model for this.  As we learned, archaeologists learn much from garbage so don’t miss what Alice said might result from a Mars One garbage dump analysis.  Todd emailed in about pets going to space settlements and if archaeologists would look for pet remains or traces of human pet relationships to learn about a space settlement.  We talked about Dark Skies and raising our awareness for specific issues, plus the need for early planning by businesses.  As the show was about to end, I asked our guest for the hottest topics in space archaeology. Alice named three topics.  The final question asked Alice to look forward five years and describe the field of space archaeology in 2019.

We welcomed Dr. William Halal to our program for a 1 hour 48 minute discussion on predictions for both near and long term space development.  In our first segment, we focused on the near term predictions that mostly centered on continued growth of space commercialization and the emergence of space tourism.  Additional topics talked about in the first segment included the Chinese space program and its possible impact on the U.S. space program, heavy lift and SLS, the space media and its potential space tourism accident response, commercial activity on the ISS, and space entrepreneurism.  Dr. Halal also directed our attention to his website, www.techcast.org which will soon migrate to www.technicalglobal.com.  Listeners asked our guest about the biggest challenges facing both commercial space and space tourism, then our guest talked about big growth possibilities with solar satellites.  Issues were addressed regarding our congress, economics, and the tensions among all the players.

In the second segment, we talked about knowledge emerging as the powerful tool of the near to intermediate term.  Dr. Halal suggested tourism would be in place around 2015 and the commercial industry would keep developing to the 2020 range.  John called from Ft. Worth to draw comparisons to our early military and aviation history, suggesting the role of the government might be to continue developing hardware and infrastructure that would eventually enhance the commercial players much the way the military aircraft had dual use with the commercial industry.  John also had comments about asteroid missions which our guest brought up in this segment.  Dr. Halal mentioned the potential of interstellar travel around 2070 and the possibility of solar satellites coming on line much sooner.  We talked about going to Mars and the Moon and about Mars One and Inspiration Mars.  Doug was the next caller and he talked about depots and large rockets, specifically for missions BLEO and the Moon.  Doug brought up SpaceX heavy lift concepts, Martian terraforming, and SpaceX orbital human spaceflight around 2017.  As our program was ending, we talked about the rate of change going on in the world today and its impact on people in different age groups.  He said we all need to be prepared for a turbulent and transformative time as he does not believe current global systems are sustainable and will have to make way for new systems and programs.

We welcomed Michael Listner back to the program for this space law review for 2013.  On The Space Show blog at the end of the summary, you will find two presentations uploaded at Michael’s request.  In the first segment of this 1 hour 57 minute discussion, Michael said it was a fruitful year for space law and policy.  He suggested that the paradigm changer was private space development, at both the state and the federal legal picture.  He talked much about the Outer Space Treaty (OST) which provides the legal basis for the U.S. to exercise control over its citizens launching anything to space anywhere in the world.  This subject came up in reference to Mars One and some statements Michael made regarding there wanting to go elsewhere to avoid Dutch law.  Michael explained how the OST presents the Dutch government with the same obligation for its citizens around the world as is the case with the U.S.  Michael then brought us current with the European Code of Conduct, current modifications, and the impact it might have on U.S. space entrepreneurs and launchers such as SpaceX.  He talked about how regulations get enforced as law & how they would make the voluntary code legally binding in our country.  We talked about the need to get an FAA launch license for private companies and how that might be unavailable depending on regulations and political issues.  For a government mission, there is no launch license requirement.  This point was stressed when using SLS for Inspiration Mars came up for discussion.

In the second segment (note we had a phone interruption so there was a short additional break though most of it was edited out), there were several email questions and comments regarding Tito’s recent Inspiration Mars congressional testimony and what it might mean for space law issues if the mission became a NASA project.  Allen asked a question about state law, specifically in California.  Michael explained the relationship between state and federal law in space matters.  During the discussion, Michael referenced many papers by different authors applicable to our discussion. Here are the links to those papers:  Henry Hertzfeld & Scott Pace: http://science.time.com/2013/11/28/hands-off-our-lunar-landing-sites-not-so-fast; National Space Transportation Policy:
www.whitehouse.gov/sites/default/files/microsites/ostp/national_space_transportation_policy_11212013.pdf; Established Practices for Human Spaceflight Occupant Safety www.whitehouse.gov/sites/default/files/microsites/ostp/national_space_transportation_policy_11212013.pdf; Space Review article on commercial spaceflight self-regulation: www.thespacereview.com/article/2252/1; FAA decision: www.gpo.gov/fdsys/pkg/FR-2013-12-02/html/2013-28405.htm.  Our guest talked about these items during both segments of our show, stressing the geopolitical component.  Near the end of the program, we talked about laws to protect the lunar Apollo landing sites and artifacts.  In his concluding remarks, our guest stressed the need to play by the rules.  Such rules may consist of state, federal, and international laws and regulations. Michael also talked about Bigelow Aerospace and his lunar cots like program suggested with NASA.

Guest:  Brian Weeden.  USAF Space Fence for national security.  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 Brian Weeden back to the program to discuss the issue of the shutting down of the USAF Space Fence.  Our discussion was based on Brian’s August 26, 2013 Space Review article, “Gambling with a Space Fence: An analysis of the decision to shut down the Air Force Space Surveillance Fence” at www.thespacereview.com/article/2357/1.  During the first segment of our 1 hour 29 minute discussion, Brian provided us with a brief history of the Space Fence, what it has been used for, its technical characteristics, and it recent cancellation partially due to sequestration regarding its approximate $15 million annual budget expense.  Brian also explained its capabilities in detecting spy satellites, space debris and other objects and the size of objects which it can detect.  He discussed both continuous wave radar and pulsed radar, pointing out that the fence which dated from the late 1950’s, was uncued.  Richard Easton called in as his father Roger was one of the developers for the space fence in January 1958.  Richard contributed greatly to our discussion.  Brian then talked about the probable replacement for the fence, an S Band fence which would result in higher frequencies enabling the detection of smaller objects, probably with a very high rate pulsed radar. Right now the S Band fence is estimated to cost about $1.8 billion but as you will hear, it may never be built.  As to how our national security has been impacted without the fence operating, Brian said it was difficult to assess so listen carefully to his analysis.  Brian also talked about challenging DOD budget issues, the difference in budget years with DOD as compared to the government as a whole, and again, sequestration.

In our second segment, Brian addressed several of the political issues surrounding the space fence issue.  When asked how long it would take for the S Band system to become operational were it funded, he said around 2018.  Two companies are competing to do it if and when the project is authorized and funded.  We also talked about the U.S. sharing satellite tracking information with all satellite operators including private companies, thus using an international partnership to finance the space fence since it benefits everyone. As you will hear, there appears to be control and sensitivity issues which prevent the air force from going that route. Later I asked Brian about stealth satellites and then he took a listener question about the way space debris was portrayed in the movie Gravity.  We spent some time discussing the impact of a movie like Gravity on the public regarding the space debris issue. As the program was ending, Brian said he was not that optimistic about a replacement fence and brought to our attention the need to upgrade computer systems that process the data.  As you will hear, this is a substantial problem that is not being addressed.

We welcomed back Dr. Madhu Thangavelu for a 1 hour 45 minute discussion on a wide ranging set of topics from space visionary concepts to HSF to Mars, radiation and other issues, fantasy vs. reality thinking, and the synthetic mind. Madhu provided us with these links relevant to our discussion:  1. AIAA talk slides:
https://info.aiaa.org/Regions/Western/LA/Lists/Presentations/DispForm.aspx?ID=6 ; 2. AIAA Space Architecture panel video on YouTube : www.youtube.com/watch?v=ig3FzB0bQnA, 3. USC Space Concepts Studio website : http://denecs.usc.edu/hosted/ASTE/527_20111, 4. latest USC Eng. magazine carries an article, p16-17: http://viterbistorage.usc.edu/Public/USCVITERBIMAG.pdf.  In our first segment, Madhu opened up by talking about students and space inspiration.  Based on his own USC teaching experience, he said students were fired up.  Our guest was asked to compare robotic missions to HSF missions and Madhu spent some time on this discussion.  He also talked about the NASA plan to capture an asteroid, referring to this as a possible wild goose chase.  He talked about the ISS and using it more and more to accomplish important space goal.  Madhu received several questions about Tito’s Inspiration Mars flyby mission.  Here, he had much to say, especially about radiation, deep space communications, food & nutrition, and even physiology degradation.  We talked about using nuclear propulsion for such a mission & he suggested a better mission profile using two Falcon rockets.

In the second segment, Paul asked about using nuclear electric propulsion as compared to the two Falcon rocket idea. Madhu talked about the nuclear propulsion history with NERVA & the use of nuclear fuel on many of our robotic missions. Michael called in and said there was no real political will for nuclear so it probably would not happen anytime soon.  Later, Madhu was asked many specific radiation questions regarding the Mars flight.  Madhu suggested possible mitigation strategies, including his favorite, self cellular repair.  Allison emailed in to inquire about his Studio students and how he holds the line from reality thinking as compared to Kool Aid thinking.  Madhu talked extensively about this issue, discussed the philosophy of idea generation, visionary thinking with some fantasy while at the same time being grounded in engineering, physics, financial and other subcomponents of the concept. Don’t miss this important discussion.  We also talked about disruptive technologies.  At the end, we talked about the synthetic mind.

Please post your comments/questions on The Space Show blog above.  You can contact Madhu through me.

We welcomed Michael Listner back to the program to discuss space debris and Apollo artifact issues along with his ideas for possible solutions to the debris problem.  On The Space Show blog, you will find three of Michael’s Space Review articles on the subject plus his Power Point slide presentation at the end of the blog summary statement.  In addition, Michael had an article in the current Space Review on the preservation of Apollo historic sites. For this article, see www.thespacereview.com/article/2290/1.  In the first segment of our 1 hour 44 minute show, Michael offered us his definition of space debris and pointed us to his slides which I urge you to have available when listening to this show. Again, his slide presentation is uploaded to the blog for this program and is the last item of the uploads.  He summarized the space debris issue as both legal and thorny!  After defining debris and the issues using the first few of his slides, he talked about other issues including ITAR, property rights, technical, and even national security issues.  Listeners asked him several questions, mostly focused on LEO as that is the most crowded region at this time and the priority for debris mitigation.  CubeSat issues came up given the potential debris problem should the cubesats manifest in the quantity talked about and planned.  We talked policy issues and different strategies as suggested by China and Russia.  We also talked about weapons issues and dual use for the military as well as for civilian use.  Michael went over Transparency Confidence Measures (TCMs) instead of new treaties and mentioned the proposed Russian/Chinese treaty, PPWT, which does not have wide support in the UN.  Late in the segment, Michael talked about the OST and the definition of a space object. We also talked about space salvage compared to ocean salvage. He told us to check out Project Azorian www.gwu.edu/~nsarchiv/nukevault/ebb305) (but did not tell us what this was.

In our second segment, Michael wanted to focus on solutions & he offered us some of his ideas on the subject. Still referring to his PPT slides.  One suggestion was to offer limited liability to third parties or those working to mitigate a debris issue, similar to what many of the commercial spaceports are doing with the suborbital spaceship companies and manufacturers.  He talked quite a bit about the proposed Swiss concept for debris mitigation which he liked very much. Michael wrote another Space Review article on this concept last year which you can read at http://www.thespacereview.com/article/2032/1.  Toward the end of the program, we talked about the need to preserve the Apollo landing sites as historical sites and some of the issues and challenged faced in doing so.

During our 11 minute plus discussion with Dr. Don Kessler, we talked about space and orbital debris problems, the most crowded orbits, mitigation theories and applications, plus international support in dealing with the problems cause over our global space development history.  We talked about specific mitigation techniques including tethers and the Swiss proposal.  When asked what the biggest problem was in terms of finding a solution, Dr. Kessler suggested funding issues.  John asked our guest to define and talk to us about the Kessler Syndrome so don’t miss that part of our discussion.  We also talked about the role of private & commercial space in both creating more debris and in helping to clean up debris problems.
