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.

Guest:  Clayton (Clay) Mowry.  Topics:  Arianespace, launch industry, reusability, launch price and satellite capacity.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, https://thespaceshow.wordpress.com.  Comments and questions should be relevant to the specific Space Show program.

This will help me bring better programming to the audience.  We welcomed back Clay Mowry to the program to discuss Arianespace and the launcher industry.  During the first segment of our 90 minute discussion, we took on the subject of the upcoming last EASA ATV 5 flight to the ISS.  Mr. Mowry explained why this program to the ISS was ending and that after this last flight, there would be only one vehicle capable of boosting the ISS.  He talked about U.S. priorities in building up cargo capability to the ISS without boost capability over commercial crew.  We also talked about the life expectancy of the ISS amid the current controversies with Russia and the US.  I asked Clay for a brief history of the launcher Ariane 5 and we learned that they now have 59 successful launches for this rocket.  Our guest talked about Ariane 5 performance capabilities plus upgrades that are in progress for an Ariane 5 ME.  We talked about launch price/cost and its relationship to how customers determine what launcher to use.  As he said the last time he was on the show, customers need launcher reliability and the ability to launch on schedule.  Launch costs are an overall factor of the total risk of the launcher, the value of the satellite, opportunity costs, infrastructure costs, and more.  This is a very informative discussion and it continued into the second segment.  Our guest also said that human spaceflight poses different issues than launching telecommunications satellites and is more sensitive to launch costs.  Listeners asked about government subsidies to Arianespace and their not turning a profit despite their commercial success. This opened up a discussion about all forms of government subsidies, including the methods used in the U.S. to subsidize and support our launcher industry.  We talked about the planned new Ariane 6 rocket and its differences with Ariane 5.  We also talked about rocket development time lines.  Rocket reusability came up and this proved to be a great discussion topic that continued into the second segment.  Clay provided us with very important perspectives regarding reusability.  Dr. Jurist called to go deeper into the issue of launch pricing, insurance, and related items. Don’t miss it.  Clay referenced several studies on this subject including the Futron NASA Ascent Study which examined launch costs among other things.  Our guest talked about ways the satellite industry is working to reduce launch costs by making satellites more powerful and lighter.  They are also starting to use ion propulsion which can cut up to 40% of the mass of the satellite which makes launches lower in cost. With more efficient satellites, longer life spans, and other advancements, its possible to see launch cost improvements up to around 20%.

In the second segment, I asked Clay what it would take to human rate the Ariane 5.  After he explained the requirements, he said their company focus was on satellites.  He mentioned Liberty Rocket, then John from Ft. Worth called in to talk about costs, depots, reusability, & just how many flights can a reusable rocket make, plus insurance risk evaluation for reusability.  Clay talked about reusability economics and risks in depth in this segment, explaining the variables and unknowns. This is an important discussion so don’t miss it.  Later by email, Jim asked about increased satellite efficiency & advanced capabilities lowering the launch rate.  Clay did not think so due to content advances and increases that offset the satellite advancements.  Again, another important discussion topic. In fact, we spent most of the balance of the program on this subject.  In concluding, Clay said the business was even more exciting today than when he joined the industry and later Arianespace.  The final listener comment asked about the launchers being the unsung heroes of our modern society.  Clay summarized that reusability had many market, technical, & economic unknowns, that HSF probably was better suited for it than satellites, & that commercial communication satellite customers need reliability & on time launches as part of their business models.

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 Charles Pooley back to the show along with his co-author Ed LeBouthillier to discuss the first Microlaunchers book,  “Microlaunchers: Technology for a New Space Age.”  For more information, visit www.microlaunchers.com. Remember, if you order the book through Amazon, please do so through the OGLF Amazon portal which is listed on TSS website, TSS blog, and in all archive summary statements.  If you have questions about this, email me.  It is important for TSS to receive these contributions from Amazon.  During the first segment of our 1 hour 33 minute program, Charles and Ed talked with us about the Microlaunchers concept and how that concept is depicted in the book.  We also learned how Charles and Ed met and the role each had in writing and completing this book.  Our first caller Jeff from Tucson won the give away copy of the book.  Jeff also asked our guests about the role of cubesats in the Microlaunchers concept specifically for LEO and then GEO.  This led to Charles talking with us about secondary payloads and why he does not favor them.  Charles & Ed then described some of the Microlaunchers launch parameters, then we took a question from Paul in Boston who wanted to ask about market concerns for the Microlauncher concept.  Doug from S. California was the next caller with three specific issues to raise with our two guests.  We also talked about payload mass and the path to a larger system, including the GEO market.  As the segment ended, Charles put forth his payload pricing goals for his system.

In the second segment, we started out with Ed describing the organization of the book into three main sections. Next, our guests fielded questions about propulsion.  Charles said they were using a bi-propellant fuel consisting of liquid propane and liquid oxygen.  Hardware issues were also discussed and our guests raised issues of how to get more awareness and visibility for their concept.  The last call came from Nels in London as we were about to end the show.  Nels wanted to know about the trades considered and used regarding the fuels and the propulsion systems our guests talked about during the program.  Both our guests left us with closing comments you will want to hear.

Please post your comments/questions on TSS blog.  You can reach our guests through the Microlaunchers website or through me. Learn more about Ed at http://home.earthlink.net/~apendragn/atg.

We welcomed Bill Harwood, the CBS News space consultant to the show.  During the first segment of our 90 minute program, Bill told us about his press conference and briefing with Elon Musk, the CTO from SES, the company sending the first GEO bird to orbit on the Falcon 9 on Monday afternoon, 11-25-13, and Ms. Shotwell of SpaceX.  Most of the first segment was spent discussing the press conference, the comments about the launch made by all participants, the challenges of doing the first GEO launch for the new Falcon 9 V1.1 and more.  Not only did Bill go over the details of the launch and the SES satellite orbital insertion, plus the Falcon 9 plans for second stage firing and getting in position for the satellite to take over for its part, we talked about SpaceX launch costs, we compared the Falcon 9 costs as best we could to the Arianne and the ILS Proton costs.  Bill was asked about the thoughts of the Falcon 9 competition and what it might mean for a SpaceX success with their first GEO launch.  Also in this segment, Bill was asked about Inspiration Mars, SLS, & Orion.  Other topics included space settlement, suborbital flight, Virgin Galactic, robotic missions, and the why that justifies HSF.  As the segment was ending, a listener asked about the Florida space coast economy and its economic recovery.

In the second segment, Bill was asked if SpaceX was creating a new market or taking market share from the existing competition.  We talked about NASA story telling for a better space policy, the JFK legacy, & space being treated by many as a luxury.  I asked Bill about the private sector being able to kick start space industry development and Bill responded with information how hard space was, especially orbital space which requires speeds of 85 football fields per second.  Dream Chaser and its recent accident were discussed and there was lots of listener support for Dream Chaser as there was from our guest.  More was said about the potential market for suborbital tourism and flights.  Bill was asked about the biggest change over the years in his covering space issues and he said it was the change in politics.  I asked him about his reporting during both Challenger and Columbia. As the program closed, Bill was asked about the ISS, commercial development for the station, and the need to keep the station going beyond 2020.

We welcomed back Dennis Wingo for this 90 minute discussion regarding space policy, budgets, commercial space, space entrepreneurism, cubesats, ISS, and much more. In our first segment, Dennis discussed his recent article, “NASA Will Face Solomon’s Choice in 2014” posted on Oct. 2, 2013 at http://spaceref.com/missions-and-programs/nasa/nasa-will-face-solomons-choice-in-2014.html.  In this article and in our discussion, our guest focused on the probability of NASA budget cuts in the current environment and the probable impact upon the agency.  Thus, NASA or Congress might find that they have to make a Solomon like choice for program funding between SLS/Orion or the ISS.  Listeners wanted to know if cutting commercial crew would give NASA sufficient funding for the other two programs.  The short answer was no but listen to the full explanation provided by our guest.  Dennis then talked about both SLS and ISS and the commercial & entrepreneurial future now developing with ISS with small satellites and space start-ups.  Referencing recent comments by Dr. Griffin, Dennis said in a perfect world with wise political leadership, we would be funding all sorts of space development projects as they create wealth, open the doors for businessmen and women with abundant opportunities and so much more but for the past 40 years he said we have not had wise political leadership. Instead. rather than investing in our future, politicians have invested in buying votes.  He talked about this issue throughout the balance of our program.  Dennis mentioned he was doing tonight’s program aboard the icebreaker Maritol docked at Pier 50 in the SF Bay.  The Maritol has become a hacker space and business incubator for small satellite and related space businesses.  In the second segment, he went into more detail about the Maritol and the eviction threat it is facing from the SF Port.  He also talked about GEO being a huge market but very costly which is why the focus is now on small satellites and developing profitable, cost effective businesses and models.

In our second segment, Tim called with several SLS, ISS, and 3 D printing questions, including asking how much mass was needed to build a Moon base.  We then talked about capital acquisition and the characteristics of ventures funded by Silicon Valley venture capital financiers.  Dennis said the timing was now right and we should adopt the zero g zero tax bill, and that we should be implementing the JOBS Act Title II which allows for crowdfunding investment.  Read about it at http://venturebeat.com/2013/09/23/crowdfunding-with-jobs-act-title-ii-the-web-will-eat-financing-and-investing.  John called in to express his views on the Solomon’s Choice options, then we talked some more about the Maritol docked at Pier 50.  Here are some articles about it: http://arstechnica.com/tech-policy/2013/10/startups-aboard-icebreaker-ship-could-face-eviction-soon-san-francisco-says (this article talks about its possible eviction & has a link to the petition you can sign to keep the Maritol in the Bay);  www.forbes.com/sites/rakeshsharma/2013/10/07/a-ship-a-couple-of-startups-and-the-bay; and here are some pictures of the icebreaker, www.nbcbayarea.com/news/local/The-Icelandic-Cargo-Ship-Maritol-127274388.html.  As you will hear, it is important to sign the petition to keep this space business incubator in the SF Bay.

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 Gordon Woodcock to the program to discuss his ISDC 2013 financial analysis presentation for an SSP power system.  This presentation is available for your consideration on after the program summary on The Space Show blog for this program per the above URL.  In addition, visit the SolarHigh.Org website for more information at www.solarhigh.org.  In the first segment of our two part 90 minute discussion with Mr. Woodcock, we were introduced to the concept of space solar power from the initial work of Peter Glazer followed by microwave expert Bill Brown.  Mr. Woodcock then discussed the need for large space transmission and Earth based receiving antennas, the need to use GEO for the SSP satellites, and some basics about beaming microwave power.  Economic & financial concepts were introduced along with the need for systems to be affordable, reusable and generate acceptable ROIs.  However, as you will hear, all of this is hard to do at this stage given the need for research and demo systems for proving out the best engineering approaches and designs.  We talked about solar efficiencies and the trade in mass with thin film lighter material with only about a 30% energy efficiency but because of their lighter weight, the trade allows us to launch & deploy bigger systems giving us more bang for the buck, so to speak.  Gordon also talked about efficient transmitter systems & the use of 5.8 GHz.  In this segment we talked about lowering launch costs, increasing the launch rate, and the competitive price for terrestrial electric power.  Earlier in the segment, Gordon  suggested the need for a one year payback but Tony sent in a question suggesting longer paybacks, all of which were acceptable scenarios as long as they were roughly competitive with highly risky terrestrial investments.

In the second segment, we talked about starting with smaller systems & demos, all followed by incremental project development.  We also talked about specific space and terrestrial antenna size and ratios as well as the size of power systems, even up to 2,000 MW or larger.  Mr. Woodcock went over the idea of raising the frequency and what this might mean for a demo as well as an operating power project system.  Questions came in regarding on orbit system repairs and maintenance.  Our guest said the systems would need to be serviced robotically.  We talked about the environment for SSP systems at this time & into the near and medium term & possible fossil fuel competition given new energy extraction methods.  Crowd funding was suggested as a way to fund some of the needed research which our guest said could be done in many competent labs in the U.S.

Please post your comments/questions on The Space Show blog.  You can contact Gordon Woodcock through me at drspace@thespaceshow.com.  Don’t forget, for those of you interested in the opportunity to submit feedback on the NRC congressionally mandated Human Spaceflight Study, please go to www.nationalacademies.org/humanspaceflight.

We welcomed Hu Davis and Bill Ketchum to the program to discuss the need for space infrastructure development, SSP, and a space leadership policy by the United States. In the first segment of our 91 minute program, we talked about the need for space infrastructure development, reusable rockets, and space solar power.  Our guest Hu Davis has a Power Point presentation on SSP that will be uploaded to The Space Show blog summary so don’t forget to check it out on the blog.  I will also upload to the blog Bill Ketchum’s pdf paper,  “What Will America Do In Space Now?”  We discussed the history of various space infrastructure studies and efforts and the same for SSP studies, pointing out how new technologies, engineering methodologies, and sophisticated manufacturing have made many projects cost effective today when that was not the case years ago.  Our guests fielded several questions from listeners about the SSP business case, reusability and the SLS compared to the Falcon Heavy.  Doug asked about the use of in space resources & our guests suggested that for SSP for example, using in space resources could account for 90% SSP components.  Questions were asked about the land cost and the use of rectennas.

In our second segment, we talked about nuclear propulsion and tax/economic subsidies to our current terrestrial energy industry which make it harder to develop SSP.   We talked about the problem and the lack of viability for SLS.  Questions came in regarding on orbit propellant transfer and cryogenic transfer development.  As our program was ending, our guests talked about space education outreach, persuading congressional leaders and the public to support space infrastructure development, SSP , and more.

Please post your comments/questions for our guests on The Space Show blog and I will make sure they know about them.  You can email either of our guests through me at Drspace@thespaceshow.com.

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.

https://vimeo.com/channels/thespaceshow  – Webinar Video

Guests:  Brian Weeden, Richard DalBello, Major General, USAF (Retired) James B. Armor, Jr..  This is a SWF sponsored webinar addressing issues related to the on-orbit servicing of satellites.  You are invited to comment, ask questions, & discuss the Space Show program/guest(s) on the Space Show blog, https://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.  PLEASE NOTE THAT THIS IS A TWO HOUR WEBINAR PRODUCTION SPONSORED BY THE SECURE WORLD FOUNDATION (SWF).  YOU CAN VIEW THIS WEBINAR AT https://vimeo.com/channels/thespaceshow.  We welcomed Brian Weeden, Richard DalBello, & Major General, USAF (Retired) James B. Armor, Jr. to the program for an in-depth discussion of on-orbit satellite servicing. This is a new business/industry that is emerging with great interest from governments, the satellite industry, & many other interested parties.  During our first webinar hour, our guests explained satellite on-orbit servicing, why the interest in it, the values on the table, & the economics behind this developing industry.  We heard from the perspective of the satellite operator with Mr. DalBello, from General Armor with the perspective of a company wanting to provide these services plus what they are commercially doing now in this emerging industry.  Gen. Armor talked about the new ATK venture for satellite repair, Vivisat (www.vivisat.com).  He was followed by Mr. Weeden who connected the dots with us regarding the big picture implications for security, stability, & policy.  We talked about liability issues, insurance, & LEO & GEO satellites in terms of their respective economic value & lifespan.  A listener asked about GPS satellites, launch costs, & competition here & abroad.  In fact, Brian mentioned several projects outside the US with the Canadians, Germans, & JAXA.  Toward the end of the first hour, caller Jack asked about testing & reliability, wondering if repairing satellites would reduce reliability engineering & testing on the ground, thus lowering the satellite’s cost given the possibility of on-orbit repair.  Ben followed asking if satellites having a longer life would be sold, comparing this potential to selling real estate once a property has been fully depreciated.

In our webinar second hour, Brian described the DARPA Phoenix Satellite Service project, http://www.darpa.mil/our_work/tto/programs/phoenix.aspx.  The issue of satellite abandonment came up & as you will hear, there is no way to abandon any object in space.  Another issue in this segment was space situational awareness (SSA).  We talked about SSA in LEO, with the new entrepreneurial small satellite companies doing LEO ventures, & the implication of this new industry for launching to & operating in GEO.  Later in this segment, we learned that there was no commercial incentive to address the space debris issue. Don’t miss the analysis behind this statement as its important in understanding the space debris issue.  A listener asked Richard about launch vehicle insurance & premiums, specifically for the Falcon 9.  Also in this segment we talked about the NASA satellite servicing mission, the Restore Mission (http://ssco.gsfc.nasa.gov/robotic_servicing_mission.html).  As our webinar drew to a close, we addressed the importance of a STEM education for our young students & the exciting space projects that today’s students will get to do in their careers. Everyone’s closing comments reflected the future orientation & focus for this evolving industry.
