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.

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

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 Howard Bloom back to the program to discuss his new book, "The God Problem: How a Godless Cosmos Creates." Remember, if you buy the book using this Amazon URL, Amazon will make a contribution to The Space Show/OGLF: www.amazon.com/The-God-Problem-Godless-Creates/dp/161614551X/ref=onegiantlea20. Howard started the discussion by telling us about the five heresies he points out in his book. That is what we see is not actually correct. A large part of the first segment takes us through the five heresies in detail in the very interesting, informative, & captive way only Howard Bloom can master. Later in the first segment, we talked about the need for O'Neill Colonies, space art, and the caption factor. In the second segment, Howard discussed his Big Bagel Theory of the Universe. (www.howardbloom.net/big%20bagel.htm and also www.youtube.com/watch?v=wdJyafSBCb0). Note that the YouTube video addresses the five heresies talked about in the first segment. Later in this segment, Howard talked about visionary space leadership, SpaceX, Elon Musk, SLS, commercial space, and the initial Obama Space Program. He also mentioned space solar power as a viable option and how to make space happen sooner, not later. He also talked about how important space development was and is to the United States, but that we are not following through on making space a priority. He said that Asia seems to understand this more than we do in the States and is acting on this truism. His new book ties in very nicely to space development, exploration, and expansion here and on a global basis. Please post your comments/questions on The Space Show blog. Howard can be reached by email at HowlBloom@aol.com. Selected by: David Livingston [ stations ], Tue, 20 Nov 2012 17:09:48 UTC

Open Lines, Sunday, 11-18-12 (71.89MB; download) -- Guest: Open Lines with Dr. David Livingston. Topics: Space Show surveys & feedback, SatCon 2012, post election space policy & more. 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.

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. Welcome to our nearly 2.5 hour Open Lines discussion on a wide range of topics. Most of our topics covered the entire show so this summary is in just one segment. In addition to a few talking points at the beginning of the show, I stressed the need for more Space Show listener feedback and the use of possible surveys. The survey issue came up with several callers and many ideas for surveys were put forth. If you have ideas or suggestions for better Space Show feedback including the use of surveys, please post your ideas on The Space Show blog. In addition, we had some strange phone line issues throughout this program. We are working to track down what happened but since there is no call waiting at our end, I'm not sure the problems were with our equipment. Regardless, The Space Show apologizes for the phone line distractions. Daniel, a first responder, called in with a brief summary of the recently completed SatCon 2012 Conference in NYC. He had some very interesting things to share with us, especially about national security satellite issues. Check out this conference at www.satconexpo.com. Tim called to talk about our recent program regarding JP Aerospace. Tim said he was working the numbers and does not feel that an airship can make it to orbit. Let us know if you agree with Tim. By the way, others on earlier programs have made it clear that they do not believe JP can get an airship to orbit. In the meantime, John continues to work the problem and best of luck to him and his crew in figuring out how to reach his goal. Doug called in and we talked post election space policy. A few other callers did the same thing including John from Atlanta. I really had no great insights to bring to the table but I suspect that more likely based on how things go with the economy and sequestration, the status quo will prevail on space policy. That said, the SLS program might actually be a target of NASA budget cuts over the next few years but it is way too early to tell. Some listeners seemed to want a partisan discussion on policy and I did my best to avoid it though I did disclose my dislike for our two main political parties. I was also clear that the private sector engaged in capital acquisition was at risk through increased regulation, taxes, inflation, etc. Like everyone, I am hopeful that risk capital will remain strong and space ventures will be able to grow in their share of this unique investor market, but it is a fragile market given our economic situation and the uncertainties ahead of us at this time. John from Winterhaven called about my comments regarding doing something with one's ideas and concepts over and above just speaking the words or writing a paper. I referred to this throughout our discussion as "breathing life" into one's concepts/ideas. I am also planning a full Space Show on this subject. Other topics included news stories on the Falcon engine problems and EML2 NASA missions. Please post your comments/questions on The Space Show blog above.

Frank Stratford, Friday, 11-16-12 (45.77MB; download) -- Guest: Frank Stratford. Topics: Human spaceflight to Mars. 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 Frank Stratford of Mars Drive (www.marsdrive.com) to update us on his latest thoughts regarding human Mars missions. You can read his latest Space Review article, "Which Way To Mars" from Oct. 22, 2012 at www.thespacereview.com/article/2174/1. In this article and during our first segment, Frank put forth two options for HSF to Mars. The first option he called the "miracle gift." The second option he refers to as "step by step." During this segment, Frank discussed both options in detail. He talked at length about what is realistic and plausible compared to being in the realm of fantasy regarding humans to Mars. A listener asked him if the less than plausible ventures were a distraction or even if they were destructive to the effort to put humans on Mars. Frank did not think so and citied YouTube hits for Mars advocacy & other groups as compared to a YouTube viral Korean song that is approaching 750 million hits (www.youtube.com/watch?v=9bZkp7q19f0). This made the point very clearly that space and even humans to Mars does not command the interest or attention of the public in any way like our pop culture. Frank also stressed the need for collaboration with the Mars advocacy groups rather then each one going its own way. He mentioned several different organizations and one that he is supportive of, The Mars Initiative (http://marsinitiative.org). Callers asked Frank about the Mars Direct plan as the segment was ending. In our second segment, we talked about how to finance a humans to Mars mission. Frank used a $10 billion price tag saying there were only a few ideas that would come in less than that but given so many unknowns about a humans to Mars mission, it was almost impossible to budget such a mission. He talked about using a Falcon Heavy, fewer flights using the SLS, a flexible financing path, and more. He also mentioned the upcoming Mars Expo 2013 in the UK which you can read about on the Mars Drive website. As the program was ending, we talked about Mars Drive and the spin-off by one of the Mars Drive supporters, Mars Drive Lab. At the end, I challenged Frank for his action plan, that is how to bring to life what we had been talking about. You will find this a most interesting discussion. Frank left us with a final selling point: "A humans to Mars mission brings us the technology and jobs of tomorrow today." If you have comments/questions for Frank Stratford, please post them on The Space Show blog. Selected by: David Livingston [ stations ], Sat, 17 Nov 2012 19:15:13 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 Dr. Sean Casey back to the show. Our first topic dealt with updates to the SOFA Project (Space Research Association for NASA's Stratospheric Observatory for Infrared Astronomy). You can find out more by visiting the SOFIA website, www.sofia.usra.edu. Dr. Casey talked about upgrades, new science programs, and more for SOFIA, plus he addressed issues specific to airborne observatories. After the SOFIA update, we turned our attention to California's Silicon Valley and the new Silicon Valley Space Center (SVSC) which is a non-profit business accelerators focused on connecting entrepreneurs with NewSpace leaders and other commercial opportunities. Visit their website for more information, www.svsc.org. The balance of our discussion centered on the activity of the SVSC with a focus to developing cubesat, nanosat, and other NewSpace opportunities. Dr. Casey mentioned several companies that suggested what he was focused on including Nanosatisfy (www.nanosatisfi.com), Skybox Imaging (www.skyboximaging.com), and GLXP Teams. In the second segment, we talked more about the SVSC and Silicon Valley in general, especially for projects outside of California. He talked more about the companies already mentioned and told us about additional entrepreneurial companies doing cubesat, nanosat, and other startup space ventures. We talked about classroom opportunities with cubesats, ways to help in commercial space projects at the classroom level, and how to engage students early on in exciting and doable NewSpace projects. Near the end we talked about human spaceflight opportunities as opposed to the science missions. If you have comments/questions for Dr. Casey, please post them on The Space Show blog.

George Sowers, Monday, 11-12-12 (40.87MB; download) -- Guest: Dr. George Sowers. Topics: United Launch Alliance, Atlas 5, Delta IV, human rating Atlas and Delta. 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 Dr. George Sowers, VP of Human Launch Services at ULA back to the show for a special one hour report on Atlas, Delta, human rating rockets, and much more. Dr. Sowers started off by letting us know that ULA recently created the Human Launch Services Division with Dr. Sowers as the Vice-President. Dr. Sowers then updated us on some of their more visible ULA activities since his last visit to The Space Show in January 2011, including probable SLS and Dream Chaser time lines, commercial crew participation and Orion tests in 2014. We talked about the ULA role in commercial crew and what was needed to human rate the Atlas as well as the Delta IV. I also asked about needed pad modifications for HSF with an Atlas and Dr. Sowers told us about modifications to Launch Complex 41 at the Cape for the upcoming crewed flights. Listeners asked our guest lots of questions about safety, pad modifications, range safety issues, and the difference in human rating the Atlas as compared to a Delta. Another question asked of our guest was to understand the contributing factors to the impressive launch success and safety rate for the Atlas rocket. Dr. Sowers answered this in some detail with attention being paid to what is known at the 3 P's. Charles wanted to know about the Russian RD-180 engines & another listener wanted to know if ULA was feeling competitive "heat" from SpaceX. Yves in Montreal asked about the dual centaur having uses other than for commercial crew and Barbara wanted to know about the role of an Atlas for possible orbital tourism with a Bigelow space station module. We talked about ULA's potential interest in new spaceports which seem to be developing around the country, then I asked Dr. Sowers about what constituted a commercial space project. Here, we learned that commercial implies largely financed by private funds, not government money. He said that EELV was developed by 80% private sector funding. We also talked about the Arianne family of rockets and their pricing which is subsidized by European governments. Dr. Sowers explained why it was so hard to compete against government subsidized pricing. Another topic of interest in our discussion was launch vehicle market and pricing elasticity and how to drive up launch rates and lower launch costs. We also talked about human spaceflight having the government as the primary leader for the market and cargo as having only an ISS market at this time. On orbit propellant depots were discussed as was SLS and heavy lift. As we neared the end of the hour, we talked about SRBs for the human rated Atlas. In our brief second segment, I went over the near term Space Show schedule and our last caller John from Florida called in to wonder if a real emergency came up if we would launch a crewed rocket/vehicle to try to save the ISS for example or would we be unwilling to take the risk and let the ISS deorbit in the example given. Hopefully such a predicament does not arise. If you have comments/questions about our discussion with Dr. Sowers, please post them on The Space Show blog.

Frank White, Sunday, 11-11-12 (51.72MB; download) -- Guest: Frank White. Topics: The Overview Effect 25 years later, still growing and expanding strong. 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 Frank White back to the program to discuss The Overview Effect twenty-five years after he identified it in his famous book by that name. Frank both described and explained what is meant by the Overview Effect, he talked about the astronauts he interviewed, their own work, and the new updated version he is working on for the AIAA. He also told us about the Overview Institute (www.overviewinstitute.org). In this first segment, the listeners asked him questions about long duration spaceflight and being unable to see Earth as the astronauts move further away from our planet, they asked about gender differences with the Overview Effect, and the difficulty that seems to exist for many people in taking their experience from space and communicating it to others. Frank told us about the upcoming film produced by a UK group, "Overview" and that it might be streamed live from Harvard at its premiere on Dec. 7th. Frank will provide The Space Show details about this and I will be sure to announce the details on future Space Show programs. In our second segment, Frank told us about his work regarding educational outreach with the Overview Effect with a UK group, Space Synapse (www.spacesynapse.com). We talked about possible use of the overview concept by NASA and national space agencies as well as in private/commercial space activities. Frank then told us about his Kindle book on Amazon, "The New Camelot." You can find it at www.amazon.com/The-New-Camelot-Volume-ebook/dp/B008WQ22RI/ref=onegiantlea20. Please remember if you purchase the book with this URL, Amazon makes a contribution to The Space Show/OGLF. Frank explained how he came to write this particular book and the significance of Camelot with President Kennedy and our Moon program. In this book, Mr. White puts forth a new interpretation of the Apollo Moon program by comparing our early astronauts to the Knights of King Arthur's Round Table. Frank suggests that the Overview Effect might just be the "holy grail" of our lifetime. We talked about the possibility of the Camelot analogy spilling over to both LBJ and Nixon. Near the end of the program, Tim called to give us a thumbs down on international cooperation in space missions, particularly if they are designed mainly for diplomacy. The three of us had an interesting discussion about international cooperation in space. Toward the end, we talked about looking forward to the private sector as the main driver for HSF and going out into space. Please post your comments/questions on The Space Show blog. You can reach Frank White through me if you want to send him an email. Selected by: David Livingston [ stations ], Mon, 12 Nov 2012 04:22:19 UTC
