We welcomed back Dr. Madhu Thangavelu to discuss current graduate student design projects from his most recent USC class which had a theme dealing with NEOs and mitigation strategies.  During the first segment of this 1 hour 41 minute show, Dr. Thangavelu focused on the future of the ISS, lunar exploration and settlements, a bit on Mars but mostly on NEO issue and surveillance of dangerous items.  He summarized several of the student projects for us including one referred to as “Trojan” asteroids and another referred to as “space rocks to take care of rocks.”  Also in this segment we talked about nuclear rocket technology and propulsion, asteroid mining, and Directed Energy devices.  For the latter, we spoke about the ease of using the technology as a space weapon.  Toward the end of the segment we discussed how to enroll in Madhu ‘s class, especially if you are not a USC graduate engineering student.  Our guest summarized the segment saying that planetary defense will happen and his class helps to train and condition creative minds to deal with the problems.

In the second segment, Professor Thangavelu received a listener question about Earthship Houses and the Cal-Earth Institute.  Madhu also spoke about the recent NASA NIAC Conference held at Stanford University.  Regarding the conference, he spoke about many of the keynote addresses and speakers, plus extremely innovative projects.  One such project was Contour Crafting which he said was now in Phase 2 (see www.contourcrafting.org).  Another listener went into more detail with him on the USC application process to attend his class, then Madhu went back to sharing more with us regarding the NASA conference.  He said keynote speakers were from MythBusters, Google, SETI, SSI, and Dr. Pete Worden of NASA Ames.  Later in this segment, he talked about the space business model with Elon Musk, Stratolaunch, and more.  He fielded a few specific questions on asteroid mining which he did not think was ripe for investor action at this time.  He was asked about green technologies & the student design projects, then about his upcoming article in the Journal of Space Philosophy.  One of the last topics was the introduction to us of co-robotics, suggesting we check it out at the National Robotics Initiative ( Google co-robotics for more information).

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm.

We welcomed Christopher (Chris) Stone to the program for a 1 hour 44 minute discussion on space advocacy and an analysis of his recent Space Review article, “Re-thinking the National Security Space Strategy: Chinese vs. American perceptions of space deterrence” which appeared on TSR November 4, 2013.  You can read the article at www.thespacereview.com/article/2395/1.  Don’t forget to read the comments associated with the article.  During our first segment, we mostly talked about space advocacy issues.  Chris was asked about advocacy groups both supporting and opposing SLS as an example of their possible effectiveness in influencing policy.  As you will hear, it seems that the influence regardless of the position is marginal.   Chris suggested that many advocacy groups are not that understanding as to who is in charge of space policy and how policy is made and how it works.  He talked about policy coming from the congressional side, the White House, and industry.  Often, both the Senate and House have at least a slightly different view of policy than the other policy participants.  We also talked about unrealistic advocacy expectations and priorities.

In the second segment, we talked about the article written by our guest for TSR per the URL above.  Chris provided his perspective on our space deterrence policy as well as his perspective on the Chinese program, plus he talked about the Chinese perspective based on his readings and work in the field.  Listeners asked questions such as the Chinese view on space settlement and their lunar plans.  Another listener asked about the policy prohibiting NASA from talking with their Chinese counterparts.  Doug called to talk about ASAT tests and the vulnerability of LEO, MEO, and GEO satellites.  This discussion took us to one about the goals of responsive space strategies.  Christ talked about space weapons and possible conflicts in and around space resource utilization.  He was asked about a possible China cislunar type of program and here he referred to a 2011 Chinese White Paper regarding space resources including space solar power.  As the program drew to a close, Chris was asked about other national space programs and his perspective on them in contrast to his thoughts on the China policy.  Don’t miss his closing comments.

We welcomed Dr. Dmitriy Tseliakhovich, CEO & CTO of Escape Dynamics (http://escapedynamics.com) to discuss their work on making microwave beamed propulsion possible for space launch.  During our 1 hour 39 minute discussion, Dr. Tseliakhovich talked about his background and passion for space, including helping to open up commercial space.  His work and experience led him to creating Escape Dynamics in 2010 to find a better and more efficient way to space than by using chemical rockets.  Dmitriy then took us through many of the benefits of external launch, including a higher specific impulse, better payload ratios, and even the ability to use an SSTO frame for the vehicle.  During this segment, we also talked about safety issues and using the possibility of using the technology as a space weapon.  During this discussion, Dmitriy was very focused and precise in saying that their systems had to prove out as being safe on all of the issues we were discussing. Next, we learned that the initial beamed propulsion vehicles would be robotic but at some point in the future, eventually crewed launch vehicles would be possible.  We talked about their step by step incremental development and testing plan, including starting with suborbital launches.  I asked our guest about the probable cost of electricity and support from the existing electrical grid.  Our guest had much to say about the cost of electricity, the use of the grid for their power needs & the capability of existing systems to support their needs.  He also did not rule out partnerships with utility companies.  Listeners sent him emails asking about competition and markets as well as the use of hydrogen for fuel.  Our guest was also asked about their heat exchanger, a key component on the vehicle.

In our second segment, Dmitriy was asked about weather issues for launch & we learned that there were concerns and requirements suggesting launching in dry areas would be best.  Another listener asked about ocean launch possibilities & Charles called in expressing skepticism, to support chemical rockets, and to raise questions about the high g force, boost stations, and the size of the ground array needed for the beam propulsion launch system. Roger emailed us to ask about orbital fuel depots & beamed propulsion.  We then talked about the company timeline & learned about 2015 as a suborbital launch target date.  In response to an email about the main challenges, our guest said the challenges to the system were mostly non-technical.  John was our last caller asking about DARPA, project financing, fuels, and more. In closing we talked about available internships and the hiring opportunities at Escape Dynamics.

Guest:  Michael Listner.  Topics:  Space debris issues and ideas for solutions.  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. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use.

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 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.

Guest:  Alan Steinberg.  Topics;  Protecting our space assets, weapons in space, space policy and public opinion.  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. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use. We do not permit the commercial use of Space Show programs or any part thereof, nor do we permit editing, YouTube clips, or clips placed on other private channels & websites. 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 Alan Steinberg to the program to discuss both is latest Astropolitics article, “Weapons in Space: The Need to Protect Space Assets,” and his 2011 Space Policy article, , “Space policy responsiveness: The relationship between public opinion and NASA funding.”  Both of these articles are available for purchase by using Google the full title of the article.  During the first half of the program, we focused on Alan’s Astropolitics article.  As you will hear, the issue of protecting our space assets is not an easy one to address or solve.  Furthermore, as Alan and listeners suggested, the response the U.S. might make to an attack on space assets is unclear, especially if the attacking party or nation had an excuse, said it was an accident, or denied intentionally doing the deed.  Alan and listener Michael defined the term space weapon and Michael provided us with the PPWT proposed treaty language defining space weapons.  Alan had much to say about protecting space assets and weapons in space in the context of the U.N. treaties.  We talked about U.S. as well as international enforcement here and in other countries.  Space debris was discussed, especially in light of the difficulty in diplomatic action leading to tangible action against a debris causing country or party.  Also discussed was government being responsible for commercial space assets under its flag.

     In the second segment, we mostly talked about Alan’s 2011 Space Policy article, “Space policy responsiveness: The relationship between public opinion and NASA funding,” although many listeners via email and the phone kept returning to the space weapons topic.  Alan took lots of questions about the role and impact on policy of space advocacy and as you will hear, its not easy or clear to pin down.  Alan had much to say on how best to influence members of congress but was clear in pointing out that space advocacy does not have the numbers of the larger and more powerful lobbying groups that are far more effective in influencing policy than is the space community.  Another of his points focused in on the significant influence of the aerospace industry as compared to space advocates and enthusiasts.  We also learned from his concluding paragraph that when researching this issue, “research on what influences space policy attitudes and even space policy public opinion is in short supply.” In addition, we learned that while Americans like our space program and NASA, they don’t have a good understanding of it, the actual amount of funding NASA gets in relationship to the budget, and that their liking of the space program simply does not translate to more funding and more programs.

Guest:  Keith Henson.   Topics SSP using laser rockets to lower the cost of space access.  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. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use. We do not permit the commercial use of Space Show programs or any part thereof, nor do we permit editing, YouTube clips, or clips placed on other private channels & websites. 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 Keith Henson to the program to discuss the use of laser powered rockets for launching space powered satellites to help eliminate the use of fossil fuels as well as lower the cost of space access.  To assist in your following our discussion, check out this laser rocket graphic at http://bit.ly/Uj9Vw9.  Also, Keith has several related published articles on the OilDrum blog.  You can download and read his articles at www.theoildrum.com/search/apachesolr_search/keith%20henson. Finally, our guest has permitted me to upload his recent PPT conference presentation to The Space Show blog, “Laser Propulsion and Space Based Solar Power.”  Please be sure to check out this presentation by visiting our blog, http://thespaceshow.wordpress.com. During our first segment, Mr. Henson talked about the need for low cost energy and said that by using laser rockets and his SSP ideas, the cost for electrical power generation could be as low as 2 cents/Kwh to GEO.  We spent a good portion of our discussion debating Keith’s assumptions behind the 2 cents/Kwh.  I referenced my costs per my PG&E invoice and other listeners emailed and called in regarding their electrical costs per their utility bills.  Keith has asked for people disagreeing to let him know where he may be going wrong so please post your comments on our blog and Keith will respond. He said several times that he wanted your critique and comments.  Many listeners as well as myself pushed him on his assumptions, wanting more factual information on how arrived at his conclusions.  He has this information pending publication with the British Interplanetary Society so for the moment, its under pre-publication boycott but as soon as Keith clears it, I will post his material on the blog and announce it on air. Later in our initial segment, we talked about the laser rocket being a weapon. This discussion sparked lots of listener participation. We also talked about SSP for insitu use rather than power beaming back to Earth.  Keith brought up the new developments with Reaction Engines out of the UK. Here is there recent press release in case you missed it: www.reactionengines.co.uk/news_updates.html. Listeners did call in to tell Keith that SSP did not make sense for a variety of reasons, including not closing a business case, with or without laser rockets.  Jerry offered such comments as did Charles. Also, without consent, AT&T installed call waiting on the toll free line. I finally figured this out & edited out several of the comments & my complaint.  The matter should be resolved for all toll free calls moving forward but about 1hr 30 minutes into the program, you will hear a rough edit where I removed the call waiting rants.
     In the second segment, we continued debating Keith’s costs plus his ROI assumptions. Fusion came up for discussion as well as already existent successful powered sat beamed energy back to Earth.  Toward the end of our program, Keith talked about his target of reducing dollars per gasoline by using laser rockets and SSP.

Guest:  Michael Listner.  Topics:  National and international space law issues including property rights, the Moon Treaty & more.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com.  Comments, questions, and any discussion must be relevant and 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 welcomes Michael Listner to the program to discuss national and international space law issues and related matters.  We started out discussing the new Austrian domestic space law and inquiring of our guest why we should take note of this Austrian law here in the U.S.  As you will hear from Mr. Listner, the new Austrian law relates specifically to the UN space treaties and plays a role in international space law.  Our guest wrote a recent article on this subject in The Space Review on Dec. 12, 2011.  You can read his article at www.thespacereview.com/article/1988/1.  Another interesting article of his you might value is in DefensePolicy.org from July 7, 2011 and titled “TCBMs: A New Definition and New Role for Outer Space Security.”  You can download it at www.defensepolicy.org/2011/michlis/tcbms-a-new-definition-and-new-role-for-outer-space-security. Our discussion then focused on launching country issues and liability, satellite operations in different countries and both the Liability and the Registration U.N. Conventions.  This discussion led us to talking about the European Code of Conduct for Outer Space Activities and Michael updated us on the status of this voluntary agreement, both on the international front as well as here in the U.S.  Other issues discussed in this segment included space debris and the Draft Russian Chinese Treaty On The Prevention Of The Placement Of Weapons In Outer Space (PPWT).  We also talked about the Chinese GPS system covering Asia, its military focus, and Chinese geo political intersects.  Michael then introduced us to Transparency and Confidence Building Measures (TCBMs) as alternatives to treaties. This prompted several listener questions and comments about “so called” government transparency, the word of governments, and their effectiveness so far.  This was an interesting discussion, especially when I asked our guest for his personal opinion on these types of agreements.  Space tourism became a subject and we spent some time on the liability issues and the states that have passed liability protection laws for the space companies.  Jack from Virginia was listening and provided us with important information about the Virginia law which he largely authored and which has become a model for the laws in Florida, Texas, and New Mexico.  We spent the rest of the first segment talking about liability and space tourism issues. In the second segment, Helen asked if funding levels for NASA and space interests correlated to up’s and downs in space policy.  As you will hear, most policy is driven by politics, not funding levels.  There were lots of questions about the legality of the Moon Treaty and its applicability to commercial space, even Google Lunar X Prize contestants.  We fielded questions on lunar mineral extractions as well as messing with Apollo artifacts on the Moon.  We then jumped over to property rights and what this actually means regarding space issues.  As we were nearing the end of our discussion, I asked Michael if space law was largely an academic field or if it was becoming a career choice field in terms of practical application.  He said it was becoming more and more practical and more and more schools were offering commercial law classes.  If you have comments or questions for Michael Listner, please post them on the blog URL above.
