We welcomed back David Vaccaro and Jonathan Beland to discuss the Futron 2012 Space Competitive Index (SCI). You can freely download the SCI Executive Summary at www.futron.com/SCI_2012.xml. The SCI provides annual statistical benchmarks, analysis, and business intelligence for both commercial and national space activities for fifteen countries, examining markers in the Government, Human Capital and sectors. Five new countries were added for the 2011 data which is used for the 2012 report. The list of countries analyzed includes the U.S, Brazil, Canada, China, Europe (all of Europe, not the individual European countries), India, Israel, Japan, Russia, S. Korea, Argentina, Australia, Iran, South Africa and the Ukraine. The five new countries added include Australia, Argentina, Iran, S. Africa, and the Ukraine. While this program was conducted using two segments, this summary is written without regard to the segments as our discussion points crossed segments throughout the program. As we started out, our guests provided us with a brief history regarding the SCI and clearly stated its purpose. Note that it is self-financed by Futron and remains completely independent of any & all pressures. Also, note that again, the U.S. remains the only country of those examined that consistently declines year by year but because our government spending is so huge and our economy, despite our problems is so huge, the U.S. remains in first place as the space industry leader of all those countries studied. Our guests told us about the benchmarks and how the SCI was constructed. They responded to lots of listener questions, including questions about why the report is not used by candidates in political campaigns, its potential influence among those in Congress and other policy makers, and the same in other countries. We talked about the impact of space industry workforce layoffs, the termination of Constellation and the shuttle showing up in the analysis and how such events might impact the U.S. score. As you will hear, our team expects the 2012 data in the 2013 report to reflect these changes in our space program. A listener asked if the SCI tracked the growth of space advocacy in the U.S., wondering why it is growing but not that much in policy impact. Other listeners asked about the growth of cubesats, especially in the U.S. and how that was reported. Also, if ITAR was a limiting factor for the U.S. Yet another asked our guests if the SCI viewed SpaceX as commercial or government subsidized in the context of the report and its analysis. When asked about a future country watch list, we talked about Viet Nam, S. Korea, South America and Mexico. In addition to lots of questions about the U.S., we talked about space in many of the other countries, why they kept investing while the U.S. seemed to be retreating. Another issue talked about was global positive view of space, embracing more and more countries, views not always held here at home. Please post your comments/questions on The Space Show blog. Both our guests gave out their Futron email addresses as the program was ending. Selected by: David Livingston [ stations ], Tue, 04 Dec 2012 17:41:24 UTC

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. Please post your comments/questions on The Space Show blog above. Keith can be emailed at hkeithhensonATgmailDOTcom. Selected by: David Livingston [ stations ], Mon, 03 Dec 2012 17:09:53 UTC

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 welcomes Dr. Roger Launius back to the program to discuss his latest book, "Coming Home: Reentry and Recovery from Space" which is a free download at www.nasa.gov/pdf/695726main_ComingHome-ebook.pdf. During our first segment, our guest provided us with a short history of resolving challenges with reentry from space with human spaceflight. We discussed winged vehicles and capsules from a historical, practical, and engineering perspective. We also talked about DOD influence and the advantages as well as disadvantages of both types of space vehicles. One listener question asked about winged vehicles evolving from suborbital to orbital HSF. Terry called in with ballistic reentry questions about the V2 rocket & we mentioned museum locations where people can see a complete V2 on display. Another listener wanted to know if there were any winged vehicle concepts for Mars. Here, our guest talked about some science fiction examples but nothing for real on the drawing board. Our guest then introduced us to magical thinking and we talked about reality in space exploration as compared to fantasy. As this segment was ending, we talked about RLVs and reentry issues. In our second segment, we started off talking about the NASA budget and the potential impact of sequestration. Our guest said human spaceflight is the biggest challenge and in fact at one point he said we were just one banana peel away from losing HSF! This was in the context of access to the ISS with only the Soyuz and how fragile the access was until we had multiple ways of getting to the station. We then discussed risk and some of the issues raised on this subject by other Space Show guests that believe we need more risk to advance human spaceflight. Risk was also discussed in the context of hypothetical ISS recue missions with HSF vehicles not yet ready for prime time. We also talked about the value and purpose of HSF, including should settlement really be the purpose of it. We had a lengthy discussion on this subject. Both Roger and I suggested the purpose of HSF is a challenge, can be illusive, and is probably something larger and broader than space settlement. Don't miss his explanation behind his thinking. We also talked about spinoffs as a reason for HSF, the we addressed the lack of needed infrastructure, radiation issues, etc. Toward the end, we took some questions about SLS and heavy lift. Jane asked our guest about the visitors to the Air and Space Museum at the Smithsonian & if Roger could infer an increase or decline in the interest in space by the visitors or if the visitors had an awareness of the challenges facing NASA and HSF. Please post your comments/questions on The Space Show blog. You can email Dr. Launius through me. Selected by: David Livingston [ stations ], Sat, 01 Dec 2012 17:56:39 UTC

Please visit the John Batchelor Show website for more information about this fine program, www.johnbatchelorshow.com. During our 11 minute discussion, Clara Moskowitz, science writer and editor at Live Science and Space.com, wrote an excellent article on the relationship of James Bond movies relative to the history of NASA with both human spaceflight as well as science missions. You can read her excellent article at www.space.com/18394-james-bond-space-movies-50-years.html. During our Hotel Mars segment, John wanted to know if government agents were pork and old fashioned in a way similar to NASA/civil space programs. Moonraker was discussed (for obvious reasons) plus we took a look at how Bond films evolved from the early days of Mercury with Dr. No to the latest movie, Skyfall, which uses advanced satellite and GPS technology as a natural part of our society and culture. We noted how the Bond space component evolution in many ways mirrors the reality with our space program. We also speculated that there might be a future James Bond on a Virgin Galactic SS2 space vehicle or a Dragon and become part of the commercial space movement.

Dr. Madhu Thangalevu, Jake Dodd, Monday, 11-26-12 (47.11MB; download) -- Guests: Dr. Madhu Thangavelu, Jake Dodd. Topics: This program discusses Jake's concept of placing a nuclear fuel plant in space in support of nuclear propulsion/space needs. 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 back Dr. Madhu Thangalevu and his student Jake Dodd to discuss the concept of SNAP-X: The Space Nuclear Activation Plant. I have uploaded his AIAA paper by the same title and his Power Point slide presentation to The Space Show blog which should provide you with more specific information about Jake's concept. Essentially, the plan calls for putting a breeder reactor in space to supply nuclear fuel for space needs safely rather than launching from Earth all the time. During our first segment, both Professor Thangavelu and Mr. Dodd explained the concept in detail. We talked about weapons proliferation in the process, the breeder reactor and why that was the chosen technology, the safety in place for this technology, and the use of it in the EML1 location and why. Part of our conversation focused in on projected time lines and development costs as I tried to get an idea of what would be involved in bringing this project to at least an Earth-based demo status. Listeners emailed and called in about the problems given the amount of fear within the public and parts of the government every time the word nuclear is mentioned, then saying that the use of a breeder reactor heightens that societal fear level. We discussed ways of dealing with this during our discussion. In addition, listeners questioned the safety of a breeder reactor and the use of Thorium as a non-weapon nuclear fuel. In our second segment, we talked more about tight budgets, private and public partnerships, and international cooperation to bring this project to at least demo status. Charles called in to challenge our guests on their Thorium comments regarding conversion to U-233 which he said was an effective fuel for weapons as was U-235. I believe you will find this exchange most useful in understanding many of the issues regarding this project. Our guests brought up the nuclear rocket history and the NERVA project, plus we asked Jake for his plan of attack in getting his project going. As our program was ending, Madhu talked about his next Design Studio Class which culminates with new student projects on Dec. 18th. I look forward to talking about many of these projects on The Space Show in 2013. Post your comments/questions on The Space Show blog. If you want to email either of our guests, please do so through me.

http://thespaceshow.files.wordpress.com/2012/11/adamo-eml2roundtripr2.pdf. We welcomed Dan Adamo back to the program and Dr. John Jurist as co-host for this special webinar addressing trajectory analysis for an EML2 mission and more. On The Space Show blog, you will find Dan's PDF document used during the webinar, a link to the movie he played in the second half of the webinar, and his Phobos-Grunt analysis paper we discussed near the end of the webinar. During the first hour of the webinar, Dan took us through the trajectory analysis to Earth-Moon L2 per his PDF document. We talked about why EML2, libration points in general, and how such missions are planned. If the resolution on the webinar video for the charts and tables used during this segment are difficult to read on your computer, please bring the document up on the PDF on The Space Show blog and follow along that way. Dan took us through Table 1, HALO orbits, and the HOI as well as the Trans-Lunar Insertion points. We talked about orbital characteristics, delta V, rocket size, and more We also talked about the position of the Earth, launch windows, the Moon, & other factors influencing the planning of the mission. While at times the discussion may seem a bit technical or overwhelming for those of us having never done mission planning at this level before, all of us will certainly have a better understanding of the factors considered and influencing both robotic as well as human spaceflight missions. Near the end of the segment, we talked about the SLS and heavy lift & how payload capacity interacts with mission & trajectory analysis. In the second hour of our webinar, Dan took us through his HD movie of the orbital trajectory talked about during the first segment, stopping it at intervals for specific explanations and questions. The movie is in the QuickTime format but you can see it both on the webinar or by using the URL provided on the blog. We took several listener calls & questions. One asked Dan about the differences in planning for the robotic vs. the HSF mission using MSL & Curiosity as an example. Dan pointed us to a YouTube video he made a few years ago with Dr. Logan using these tools for a Deimos mission (www.youtube.com/watch?v=X10GAqA4Ky4). Another listener called wanting to know the likelihood of an EML2 mission actually happening. Dan explained why he believed this mission to be the next stepping stone in HSF. More was discussed about SLS with Dan raising some concerns about its real capabilities & wondering if Congress is being sold unrealistic expectations. We talked about heavy lift in general & with the support of properly placed depots. SLS and the difference with a Falcon Heavy were also discussed in terms of what the differences would mean in payload, number of launches, costs, risks, etc. Please post your comments/questions on The Space Show blog. You can contact either guest through me. Selected by: David Livingston [ stations ], Mon, 26 Nov 2012 17:17:49 UTC

Dr. Marcelo Vazquez, Friday, 11-23-12 (45.45MB; download) -- Guest: Dr. Marcelo Vazquez. Topic: Galactic cosmic radiation & human spaceflight in deep space. 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 back Dr. Marcelo Vazquez for deep space radiation updates since his last visit to the show on August 22, 2006. In our first segment, Dr. Vazquez updated us with new information about Martian surface radiation due to the instruments on board Curiosity now roving on Mars. We talked about the meanings of the findings so far and the good news for astronauts visiting Mars as we are learning that being on the surface will likely be doable. We then talked about transit times to and from Mars and why that presents a different set of radiation challenges. For our discussion, we only referenced existing, operational propulsion - chemical propulsion. We did not talk about advanced propulsion travel times or nuclear propulsion travel times as our focus was on what was available today, not what may be available in the near or intermediate term. The Galactic Cosmic Radiation (GCR) is a problem with lots of unknowns. A further complication is a solar event but that could probably be shielded for with an onboard shelter. Not so with the GCR. Dr. Vazquez even pointed out that GCR may cause an incomplete mission as it impacts the central nervous system & that might be a bigger risk than cancer at the end of the mission. Listeners emailed & called with radiation questions, even asking about the difference in GCR and radiation here on Earth. Other topics addressed in this segment included the use of older astronauts given they might suffer less radiation damage than a younger person, cell damage and division, timelines for potential solutions, & space settlement/family issues in light of what we know about space radiation today. In our second segment, we talked about Cislunar space, EML1, EML2, the lunar surface and NEOs in light of radiation dangers for astronauts. The ISS was discussed within the context of Martian surface radiation, along with the South Atlantic Anomaly and polar/equatorial radiation on Earth. Listener Bruce emailed about Marcelo "slightly over stating space radiation." I read the email on air so do listen to the response given to Bruce. Dr. Vazquez then talked about the NASA guidelines & the number of safe deep space radiation days for an adult male and an adult female (they differ). Near the end, a NYC first responder called in about possible radiation incidents in NYC & treatments available, including new medicines. At the end, I asked out guest for success indicators. We were directed to note the biologic focus given GCR can directly impact a molecule. We concluded with a short update on radiation used in cancer treatment including proton and carbon ion therapy. In summary, no show stoppers but lots of challenges that Dr. Vazquez believes will be resolved through future research. Please post our comments/questions on The Space Show blog URL. If you want to reach our guest, you can do so through me. Selected by: David Livingston [ stations ], Fri, 23 Nov 2012 23:47:37 UTC
