We welcomed Howard Bloom back to the show for this two hour 6 minute complex space policy, leadership, commercial space and more discussion.  During the first segment, Howard worked us into discussions about space and pop culture, space leadership and policy issues, commercial and private space issues, and the SLS as representative of extreme pork taking down the space program.  This conversation included many side tracks including space art for inspiration, Von Braun, Chesley Bonestell, and more.  We talked about The Space Development Steering Committee, their focus on private space as well as space solar power (SSP).  As you listen to this program, you will realize this is not an ordinary Space Show discussion on these topics as Howard brings to us very unique and very broad important perspectives with important information.

In the second segment, Chuck Lauer called in to talk about the Darpa XS1 suborbital program and his company submission.  Later, Howard talked about Dragon and Cygnus plus the significance difference between the two.  He advocated for fuel depots and space infrastructure.  I asked Howard about a timeline for realizing the development/implementation of the project he was talking about.  He also talked about the ISS, Mars, Phobos, and L1.  Near the end of the discussion, Howard talked about his two Kindle books available on Amazon, “How I Accentually Started the Sixties” and “The Mohammed Code:  Why a Desert Prophet Wants You Dead.”

Please post your comments/questions on TSS blog.  Howard provided his social media and email address during this show for contact and for joining The Space Development Steering Committee.

We welcomed Dr. Don Flournoy to the program to discuss the upcoming SunSat Design Competition (www.nss.org/news/releases/NSS_Release_20131028_SunSat.html).  Information about the SunSat Design Competition, the guidelines, prizes and all the details can be found at http://sunsat.gridlab.ohio.edu/node/7.  During the first segment of our 1 hour 25 minute program, Dr. Flournoy introduced us to the International SunSat Design Competition along with the concept of Space Solar Power (SSP).  We talked about the competition, the role of the NSS and also the SpaceJournal which our guest edits, www.spacejournal.ohio.edu (The Online Journal of Space Communication).  Specifically, Don referenced Issue 17, then later Issue 16.  He talked about the need to do proper story telling in a visual format, the need to have your design be technically doable, and include a business plan.  He described the top prizes of which there would be a few at $10K each.  We went over design contest logistics, due dates, the guidelines which are on the above URL and more.  Don then talked about the fundraising involved by the competition, the need to raise sponsorship dollars, crowd funding, and more.  One listener asked if an entry could focus on the launch problem related to SSP.  Yes, that was acceptable.  We talked about the rectennas and he pointed us to an article about this which was posted on Issue 17.  Randy wanted to know if the policy aspect could be an entry since that would be short on the technical component. Again, yes since policy and legal are clearly part of the solution to implementing SSP.  Demo projects came up, especially in reference to nanosatellites and cubesats. Don told about the presentations that take place at the ISDC meeting in May.  We talked about other countries interested in SSP& their role in the competition.

In the second segment, we started with a call from Seth who is member of Don’s Advisory Board.  Seth had additional information about the competition to share with us, plus he talked about the overall educational value of the design competition and work that Don was doing with his students and the online journal.  Don referenced his work with non-technical students, the need to do visualizations for the project, and the work coming out of the Grid Lab.  Don told us about the course he teaches which focuses on creative visualization for science & technology plus how to use social medial.  Our guest was then asked about the potential impact of a demo project and how that might change the project development timeline.  Near the end of the program, Dr. Flournoy was asked about using the Moon for SSP, then he again went over the requirements for entry, including the need to include a business plan. As we were ending, a listener asked him about outreach efforts to policy makers, Congress, staffers,& others, plus their overall interest in SSP.  He was also asked about his student’s reaction to the competition and the overall idea of SSP.

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.

We welcomed back John Strickland for this two hour discussion on a wide range of topics of interest to the NewSpace, commercial space, and space settlement audiences.  John started out by talking about the upcoming NSS ISDC Conference in San Diego from May 23-27.  For more information visit the NSS website, www.nss.org and click on the ISDC link.  Some tracks are still open for submitting abstracts so if this interests you, click on the appropriate link at the ISDC site.  During this part of our discussion, John talked about the NSS Roadmap and the planned coverage of it at ISDC 2013.  John was then asked about the deep space commercial and Mars ventures announced in 2012 and so far this year.  He said they were helpful to the overall space settlement agenda and explained how in his discussion comments.  He added that the Mars missions and Golden Spike were “laudable” but suggested we may not be ready by the time the projects give for doing the venture. He later said he would have spent the money differently.  Don’t his miss all his comments on these new commercial and HSF missions to Mars.  Our conversation then focused on the problems of sequestration and then John talked about heavy lift and SLS.  Our next discussion topic was Space Solar Power (SSP).  Here, John took us through a detailed analysis of why terrestrial solar and wind is not the best way to go, then he went through some of the characteristics of SSP and why it is the preferred way to acquire much of our energy. This is a detailed and at times marginally complex discussion but one you will want to hear.  In the end, he suggested we delay until we have the bigger launchers such as Falcon Heavy or bigger to make the launch component more economical.  His analysis included total energy needs for a city, Texas, the U.S., globally, etc.  It is a very instructive discussion.  Near the end, he said we should not put all our eggs in one energy source basket.  Listen to his solid explanation for this suggestion.

In our second segment, John talked about launcher reusability and more regarding SSP.  He introduced us to space logistics, commercial docking with cargo to the ISS, & the need for reusable deliveries, thus the RLV.  From here, he talked about fuel depots, mostly at Earth-Moon L1 and L2.  He explained the boil off problem, the cryogenic transfer problem, and the need for good insulation plus a cryo cooler.  Other issues in this segment addressed a lunar base, plausible time lines for accomplishing much of what our guest talked about, the Chinese space program and the complicated US-China relationship.  Near the end, a listener asked about a possible Texas spaceport per suggestions of SpaceX.  Tim called just before the end of the show to talk fuel depots, types of propellant for the depots and then he mentioned the VAPAK process (see http://ralph.open-aerospace.org/PDF/2009.04.14%20-%20HCG%20White%20Paper%20-%20VaPak%20Overview.pdf.)

We welcomed Dr. Henry Hertzfeld back to the show for a fascinating 90 minute discussion regarding commercial space, human spaceflight (HSF), recently announced HSF Mars missions, increasing the launch rate, and more.  During our initial segment, Dr. Hertzfeld addressed my question about lowering launch prices to increase the launch rate.  Dr. Hertzfeld did a classic economic study on this subject several years ago and I asked him if today’s current market and commercial space progress had altered his earlier conclusions.  He said no. Later, I asked if space solar power (SSP) could drive launch rates down.  The short answer was no but don’t miss what he had to say about SSP economics, launches, and debris issues.  Jerry emailed in a question about SpaceX being a commercial company given its receipt of government money.  Henry had much to say about what makes a company commercial or not and if it is even an important issue.  Another listener wanted to know about the deep space commercial ventures announced in 2012 and in 2013.  The listener wanted to know if these were really commercial ventures, if regulations could stop them, and what would happen re the ventures needing property rights or the equivalent.  One of the things our guest reiterated several times during our discussion was the need for stability and predictability for the commercial industry.  Questions came in about benefit sharing and he mentioned the likelihood that some sort of international system would develop on these issues. I asked what constituted an acceptable ROI and the example of controlled ROIs as in the utility industry came up.  Doug wanted to know about rocket reusability and its impact on launch costs.  We also talked about both Mars One and the new Inspiration Mars mission.  As part of this discussion, astronaut rescue and the rescue treaty were discussed.  In the second segment, Doug called to discuss property rights for a NEO as opposed to the Moon, wondering if the Moon might be more valuable.  Doug & Henry talked about our having returned lunar rockets as a model for commercially returning lunar products but Henry suggested there might be a difference in returning something for science as compared to commercial exploitation.  Later, we addressed human spaceflight and its challenges.  The Chinese space program was brought up as was the risk of a space war.  Dr. Hertzfeld was asked about putting 10,000 people on Mars, space migration, species survival, space settlement, and the need to explore as possible drivers for HSF.  My final question pertained to our evolving to a business friendly environment in space.  Simply put, we are not there yet.

We welcomed John Strickland to the show to discuss cislunar space development, economics, transportation, SSP, and much more. You can read his latest The Space Review article, “Cislunar transportation: the space trucking system” at http://www.thespacereview.com/article/2221/1. We have also placed on The Space Show blog several images John referred to during our 96 minute discussion. We started the first segment by discussing what is needed in terms of supporting space infrastructure to establish a Cis-lunar space economy. In addition, we talked about heavy lift launch vehicles in general, expendable rockets, the need for RLVs and more. John said there were three basic vehicle needs, a crew vehicle, cargo vehicles, and tankers. At one point he said he would like to see a Dragon model as a tanker. This discussion then went to orbital fuel depots and our guest had much to say on the depot topic. Here, he brought up the idea of a lunar ferry and robotic missions using the RLV. A listener asked him for the biggest challenge to the ideas he was sharing with us and he said money!

     In the second segment, Doug called in and talked about John’s Space Review article per the above URL. Doug had several questions and challenges for John. Another listener emailed in questions relating to John’s trucking system comparisons. Later, Tim called to ask about electric propulsion and this took us to the Falcon Heavy topic, the need for RLVs, etc. Also, John referred quite a bit to Image #2 on The Space Show Blog, the LMO Waystation.

Guest:  Hoyt Davidson.  Topics:  Commercial space financing, markets, and risks.  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 Hoyt Davidson to the program to discuss commercial space from the perspective of markets and financing.  Mr. Davidson, founder and managing Partner of near Earth LLC (www.nearearthllc.com) shared with us his expertise and experience in a very instructive discussion on these important topics.  While much of the focus was on the commercial satellite industry, the applications apply across the board in the commercial space industry.  One of the topics we discussed in great detail was market risk. In fact, our gust suggested market risk was a bigger challenge and more of a possible road block than technical or regulatory risks.  Mr. Davidson also said what many others in the commercial space arena say and that is that the companies prefer to see themselves within their overall general industry such as media and communications rather than as a space company.  We talked about several popularly touted possible commercial space industries from a market perspective, the length of time needed for a return on investment, and what is referred to as Death Valley for space entrepreneurs.  Death Valley refers to an opportunity being too large for an angel investor but too small for venture capital.  In talking about market risks, we also talked about getting investor partners to strengthen the deal. XM Radio was cited as an example.  The pursuit of market research was discussed, both from the perspective of using a market research company and doing the market research in-house. Other potential commercial space industries were examined including space tourism, citizen science for orbital with cubesats as well as suborbital, space solar power, satellite internet services, and the use of public/private partnerships.

In our second segment, a listener wanted to know about space focused investment banking career opportunities for MBA graduates.  Next, we talked at length about public/private partnerships and being “pure” regarding what constitutes a commercial space company.  In this context, pure refers to not having a mix of government and private capital, instead being 100% private. SpaceX with Cots and Commercial Crew served as one of our company examples but we also noted that no such 100% pure private company was out there given the costs and challenges of space ventures.  Listeners asked about private capital financing for NASA science missions such as a Europa mission.  Other listeners wanted to know about commercial opportunities for human spaceflight. Here, our guest suggested the opportunities were more with the robotic missions that come before the human missions.  Toward the end, a listener asked how higher tax rates might impact risky commercial space investments.  We also talked about geographical areas of special investment expertise in the U.S. and in other countries. Silicon Valley is not the only player in this field.

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.

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.

Each of us mentioned some new themes we are interested in once the blog becomes active again, probably by September at the latest.  A new feature of the rebirth of the Cynics blog will be the opportunity to be a guest Space Cynic blogger.  Details on this will soon be posted on the Space Cynic blog but we did mention of few of the obvious guidelines during our discussion.  We also talked about making comments on the blog and opening up the Walking Eagle Award to a blog reader nomination process.  Note that I will archive this program on Space Cynics as well as The Space Show blog but do understand that The Space Show has no formal relationship to Space Cynics other than as an individual, I am one of the four space cynic contributors.  We welcome your feedback on bringing the Space Cynic blog back to active life.  Post your comments on either blog or both of them.

If you want to email either of the guests on this show or space cynic founder Shubber Ali, you can do so through me and I will forward your email to the person of your choice.

Guest:  Dr. Lewis Fraas.  Topic:  Mirrors in space for affordable solar electric power.  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 welcomed Dr. Lewis Fraas to the program to discuss his MiraSolar Satellite Concept for mirrors in space for solar electric power.  I have posted two of his presentation papers and slides on The Space Show blog for your review.  You can find more about his concept by visiting his website, http://jxcrystals.com/lendrupal.  At his website, go to the lower right corner for links to MiraSolar.  As our discussion addressed common topics throughout our 90 minute program, I’m writing this summary without regard to program segments.  We started our discussion by asking Dr. Fraas to provide us with an overview of his mirrors in space concept.  This he did, drawing from time to time upon comparisons with space solar power concepts placing their satellites in GEO while the mirrors would be in LEO around 1,000 km.  Dr. Fraas made comparisons with SSP and mirrors in space throughout our 90 minute discussion.  We talked about optics and physics as well as the power generating size of the ground stations used in his concept, comparing those to nuclear power plants and other power generating facilities.  I believe you will find the power comparisons most interesting.  We spent a considerable time going over the launch and project economics as well as due diligence from a mostly economic perspective.  As you will hear, there are some blanks yet to be filled in but since this project is a decade or so out in the future, it is challenging to project values and costs that far into the future, let alone what launch vehicles we will have along with their flight, payload, and price characteristics.  Another important part of the discussion focused on ground stations.  Dr. Fraas zeroed them out of the economics when the ground station was built for or was being used for terrestrial solar as the mirrors in space project can make use of the same station.  In cases where the mirrors program needs its own ground station, those costs would be factored into the total project costs.  Listeners asked about environmental issues, an EIR and its challenges. Dr. Fraas made a point of being clear that this was an international project, not just focused on the U.S.  He also suggested that there was a possibility of limiting or restricting U.S. regulations down the road but that other countries might be more interested in mirrors in space, including China, Japan, and India. We had an interesting discussion about the U.S. and the space progress being made in other countries.  Tony asked a series of questions pertaining to using more not fewer mirrors for terrestrial solar farms.  He also wanted to know the launch price that made the project viable.  Dr. Fraas referred to NASA and other studies and cited two reference launch prices.  See what you think when you hear this discussion.  Another topic dealt with radiation at the orbit Dr. Fraas discussed. Here, we talked about the inner Van Allen belt and thanks to a listener, we got some info on debris issues at the desired orbit.  Don’t miss this discussion.  As we heard, it might be advantageous to shift the orbit to 1200 KM for debris mitigation purposes.  Another discussion topic addressed competition with always improving terrestrial forms of energy under development and in the process of coming on line.

You can email Dr. Fraas for more information at lfraas@jxcrystals.com.  Please post your comments/questions on The Space Show blog and I will be sure to call them to the attention of our guest.
