We welcomed Dr. Gruntman back to the show to discuss his new book, "Intercept 1961: The Birth Of Soviet Missile Defense" along with the subject of missile defense in both Russia and the U.S. today. During the first segment of our 1 hour 44 minute program, Dr. Gruntman first started out by telling us that the USC Department of Astronautical Engineering was now in its tenth year. He described the program & how it differed from other aerospace engineering programs at universities across the country. I asked Mike about the classes he teaches and has taught & as you will hear, his classes have been extremely popular with upper division and graduate students. Dr. Gruntman then turned his focus to his amazing and very unique book, "Intercept 1961: The Birth Of Soviet Missile Defense." While I took elaborate notes during our discussion to serve me in writing up the summary of the program for our archives (as I do with each show), Dr. Gruntman, listeners through emails and phone calls, plus my questions, covered so many important historical as well as current and strategic topics that doing any type of "blow by blow" summary would short change what you will hear on this program. As a result, I am choosing to summarize our discussing by referring to themes and big picture issues for the most part instead of reporting on the incredible detailed information Mike shared with us. We started out talking about the little known Soviet Union missile defense program starting in the 1950's. The program was not part of the space program or the Soviet military but instead was part of air defense. It was very secretive. The early Soviet program was significantly advanced over anything the U.S. had at the time, especially with the first Soviet intercept March 4, 1961. Mike then explained in amazing detail the Soviet program, the research and development, targeting, nuclear destruction as opposed to the direct hit. He talked about rocket and warhead as one unit, then the development of the capability to separate the warhead for its own incoming trajectory along with the intercept difficulty of figuring out what was the useless rocket body as compared to the warhead which was the intercept target. As we discussed this subject, listeners asked Dr. Gruntman about early US missile defense weapons and our program. Also in the first segment, we talked about using nuclear weapons for the intercept because guidance and targeting was not yet advanced enough for a direct hit kill. This led to several discussions about nuclear explosions and their effects in the upper atmosphere where the intercept would take place.

Please note that audio and transition issues are a result of copying the John Batchelor broadcast & are not within my control as they originate in the Batchelor studio. John Batchelor and I welcomed Dr. Robert (Bob) Zubrin to the program to discuss the NASA Road to Mars per the Evolvable Mars Campaign: Status Update as published Sept. 22, 2015 by NASA Spaceflight.com at www.nasaspaceflight.com/2015/09/sls-manifest-phobos-mars-2039. John and I asked Bob about parts of the plan including 41 SLS launches, cislunar development missions, a mission to Phobos and then finally in 2039 a Mars surface landing. Bob was highly critical of all stages of the plan. He also said it was the subject of a big debate at the recent Mars Society Conference. You can see the debate Dr. Zubrin referenced at www.youtube.com/watch?v=Oo4-ros2yEk&list=PLn0lnGc1SaimPHpRoH0XlwiCih-jYjC7F&index=11. Bob called the NASA plan absurd, was highly critical of plans to go to Phobos saying the science was at Mars, not on Phobos, plus he described orbital challenges and difficulties created by going to Phobos. Several times he said the plan was nothing more than a way to spend money on NASA projects. Near the end of the segment I asked Bob about the plan being sustainable and also leading to the settlement of Mars. You can imagine his response to my questions. In summary, he said a humans to Mars mission needs to be done from start to finish within the two terms of a president, not spread out over 25 years as is the case with the NASA Road to Mars program.Please post your comments/questions on The Space Show blog above. You can email Mr. Batchelor or Dr. Robert Zubrin through me at drspace@thespaceshow.com. Dr. Zubrin can also be reached through The Mars Society website, www.marssociety.org.

This will help me bring better programming to the audience. We welcomed back Gerald Driggers to discuss his August 10, 2015 Space Review article, "Reduced Gravity: The 400-kilogram gorilla in the room." You can read & download this article at www.thespacereview.com/article/2802/1. During the first segment of our 1 hour 42 minute discussion, Gerald talked about the old concept to put a centrifuge on the ISS but of course that never happened. Much of the first segment our guest and listeners lamented the lack of attention to mitigating problems caused by microgravity by developing some form of artificial gravity as the standard mitigation tool. Gerald referenced several studies in support of the need for artificial gravity, including one only a year or so old. Listeners asked him about minimizing travel time to a destination, say Mars, as a way of mitigating microgravity issues. We talked about that but Gerald pointed out that at the destination you would still be in a less than 1 G earth gravity environment so what then? I asked Gerald if being stuck in LEO for decades might have contributed to the lack of NASA progress in this area. Kelly sent in an email asking several things, including a question about spin rates. Kelly also wanted to know why artificial gravity had been ignored for so long, suggesting the possibility that advocacy groups disregard it. I did not support Kelly's contention as I have done many Space Show programs with advocates pushing for artificial gravity and even coming up with their own plans on how to achieve it. Gerald was asked about tethers. His response triggered a lengthy email from Joe Carroll on the subject which I will post for Joe on the blog for this program, then Joe called the show in the second segment. Gerald was asked about artificial gravity work going on in other countries & with other government space agencies. He also talked about the need to really just test for Mars and lunar gravity given the relationship of these numbers throughout our solar system to other planets and moons. In the second segment, Gerald talked about his science fiction book series, "Earth Mars Chronicles" plus the long scale settlement of Mars. At this point Joe Carroll called to talk about his email, tethers, and the artificial gravity issue. Don't miss the fine discussion with Joe and Gerald they brought up many facts about the situation, the 2010 National Space Policy and more. Joe referenced the Fresno Underground Gardens as a possible example of underground living which he said would be necessary due to radiation. There would be no on the surface living.

This will help me bring better programming to the audience. We welcomed back Anthony Young to discuss his new book, "The Twenty-First Century Commercial Space Imperative." During the first segment of our 92 minute discussion, Anthony talked about writing the book as part of the Springer Briefs In Space Development Series. He talked about commercial space emerging into a huge venue, then he outlined the format of his book which is for the most part the book's Table of Contents (check out the book's Amazon page to read the Table of Contents). You can follow along with us as our guest discusses the major topics and themes based on the Table of Contents. During this segment, I sked Anthony why he thought commercial space was the twenty-first century imperative. Don't miss his response to my question. Other topics discussed in this segment included entrepreneurism, start-ups, even NASA projects. In chapter 2, Anthony talked about game changers in the industry. Here, he specifically cited SpaceX and Stratolaunch. Later, he included the developing cubesat industry and then in a later chapter, he cited the personal spaceflight industry. Anthony talked about reaching students and addressing the issues surrounding STEM, plus he talked about what was happening with private space outside the United States. In the second segment, we talked about the upcoming movie, "The Martian" and the fact that it addresses a government mission and has nothing to do with commercial or private space. Anthony cited a recent headline he had seen saying the movie would do nothing to advance commercial space. Returning to the Moon came up next as did international projects which he said were a significant contributor to global peace. Near the end of the segment, a listener asked about the impact of the SpaceShip 2 accident and our guest talked about the NTSB findings. Despite the accident, he said their was significant potential for growth in the personal spaceflight segment of the industry, both for suborbital as well as for orbital flight. Anthony was asked about both the role and risk of government regulation in the emerging commercial space industry. As we were nearing the end of the program, I asked him for his thoughts on what the industry would look like ten years from now. Before our discussion ended, Anthony said he was working on a another book regarding the Apollo lunar samples. Please post your comments/questions on TSS blog per above.

Visit their website for more information, www.shackletonenergy.com. During the first segment of our 1 hour 47 minute discussion, Jim introduced us to the Shackleton Energy plans for space development by solving the terrestrial energy problem facing Earth. The program Jim outlined is expansive and at times complicated so you will want to pay extra careful attention to our discussion. Jim talked about creating the Off World Foundation and the Off World Consortium which he fully explained in this segment. He also said the real path for space development required solving the earth's terrestrial energy problem. He then explained his multi-billion dollar program which is in three phases starting with propellant depots, then lunar mining and manufacturing, followed by the establishment of space based solar power. Our guest talked about the many challenges but noted that investor caution was prevalent along with risk uncertainty. In this segment, he talked about the market, consortium participants, timelines, business and industrial challenges, and more. He also outlined the assumptions used in designing this program. In the second segment, Jim talked about the Outer Space Treaty, regulatory barriers, rectenna placement, power distribution to the poorest and most needy of countries first, space advocacy, space settlement, the traditional space industry, and technology readiness levels (TRL) for the development of Off World program. Jim answered questions about program costs, suggesting that the first phase mentioned earlier would cost around $18 billion! He outlined the additional program costs and timelines, plus revenues received along the way being reinvested in the program. We talked about comparisons with other industries such as the oil and gas industry and their support for the Off World program. Several times in this segment Jim said this was the best way to drive the development of space and eventually space settlement. At the end of the segment, Jim offered a detailed conclusion & summary for the Consortium to solve the issue of terrestrial energy through the use of space. Please post your comments/questions on TSS blog above. You can reach Jim Keravala at the email address he gave us at the end of our program.

This will help me bring better programming to the audience. We welcomed back Bob Zimmerman for a two hour discussion plus updates on the space industry, including commercial space and NASA's planetary science program. Bob started out by saying that the commercial space industry was heating up and getting more competitive, citing two significant stories. First, he mentioned the Blue Origin announcement about opening up a Florida launch site. Next, he addressed the SpaceX news regarding new commercial launch contracts with ARAB SAT and also the Falcon Heavy (FH) with demo launches to start in 2016. Bob spoke for some time on the FH, plus he talked about recent Russian Proton successes with their having said they found a systemic flaw in the Proton system but now that it was repaired, they expected more successful Proton flights. Virgin Galactic was next up for discussion and here Bob said the news was confusing. He spoke to the recent company announcements about Launcher One, then upon my asking, said that SpaceShip 2 seemed to be getting less attention for now. Bob mentioned the possible NASA use of a low cost Dragon capsule, then Jonathan Evans started in asking a series of questions, the first inquiring about what makes more business sense, Blue Origin's expansion plans in Florida at Kennedy or SpaceX's expansion plans in south Texas near Brownsville? After responding to Mr. Evans, Bob had much to say about ULA, the proposed Aerojet Rocketdyne buyout bid of ULA, plus the overall competitive nature of ULA in today's rocket environment. Bob got a question from Jim who wanted to know his thoughts on XCOR given what he had said earlier about Virgin Galactic. Bob was not that positive about XCOR, joking that Charles Lurio would probably call in to rebut his comments. This prompted Dr. Charles Lurio to call in to "correct the record" and the mistakes Bob was making regarding XCOR and their progress. When Charles called in, he had much to say to set things straight. In the second segment, our first call was from Dave in the Chicago area. Dave spoke about Blue Origin and ULA deals plus the ACES upper stage. Later, Bob went after the SLS again, mostly on its costs being too high. John from Ft. Worth called and the two of them had an interesting exchange on several related topics. Bob next mentioned the Rosetta mission and the Philae Lander, then he switched to the planetary science missions and programs. Bob had much to say that was positive on these missions including Cassini, New Horizons, and Curiosity. Later, Jane asked when space policy would enter the 2016 presidential race. Bob did not think it would enter the race, plus he did not want it to become a campaign issue. Listen to his comments and see if you agree with him.

This will help me bring better programming to the audience. We welcomed Dr. Pat Hynes back to the show to talk about this year's ISPCS to be held in Las Cruces, NM from Oct. 6-8, 2015. For detailed information about the Symposium, hotel & conference registration, please visit www.ispcs.com. Initially our program was to be on the 60 minute format but as our discussion progressed, it extended beyond our usual 90 minute plus program to 1 hour 37 minutes without a break. As a result of this, the program summary has been written for a one segment program. We started our discussion with Dr. Hynes talking about commercial space and how the industry and the Symposium had changed over the past eleven years. Dr. Hynes described the basic logistics and style of the Symposium as it is a complete package from morning to evening, including food, snacks, total hospitality and more. The agenda which covers two full days features 42 speakers, all speaking as keynotes, typically for 18 minutes with a 10 minute Q&A. The theme for this year's symposium is "Make A Difference" and Pat talked about this in the context of people wanting more than just a job, instead wanting to make a difference in what they do. Later as the program was ending, we talked diversity with women and minorities and again making a difference was a top priority. Unlike a traditional conference promotion Space Show program, we did not simply follow the agenda and the scheduled speakers and panels. While Dr. Hynes did highlight speakers and panels, she did so in a big picture way to stay focused on the theme and to let us know just what went on behind the scenes in selecting speakers and panel subjects for this year's Symposium. Pat honed in on specific topics such as the Virgin Galactic accident, the NTSB report, and human factors issues, plus the need for balanced risk taking in developing the commercial spaceflight industry. Pat also brought up the proposed Aerojet Rocketdyne bid to buy ULA for $2 billion. This led to a discussion about the ULA and Blue Origin relationship, the Boeing and NASA culture, and how this year's Symposium would be addressing these matters. Much more was said about this subject, including the use of Twitter and social media. Cargo resupply was brought up with the various players/participants as was the suborbital and orbital industry. We took a call from space attorney Michael Listner who talked about the need for balanced risk taking. Michael mentioned his Op-Ed in the current Space News issue titled "Space Has Its Place in U.S. Presidential Race." Pat mentioned large new players in the industry including Google, BlackSky Global and others.

This will help me bring better programming to the audience. We welcomed Dr. Doug Plata back to the show to discuss his space advocate projects that he has already done. In addition, he created a wish list of future advocate projects that he wants to do on his own or in collaboration with others. His 27 page Power Point Presentation detailing all of these projects has been posted to The Space Show blog so please take a look at it and follow along with us during the discussion. Dr. Plata's discussion follows the PPT page by page. You can see it at http://thespaceshow.wordpress.com. In the first segment of our 2 hour 7 minute discussion, Doug explained why he does these projects citing having fun as a major motivating factor. He does go through the PPT topics and slides in order so rather than going through each one here in the summary, follow along with the PPT presentation on the blog. Some of the project had a more detailed discussion than others such as the theme park ride, the Gravitron which came up in the second segment. Listeners asked him several email questions on a variety of topics including how he could open up his projects to collaboration with others that were not physically in the same location or area as Doug. Doug was also asked if one needed an engineering, physics or other specific background to do what he was doing and Doug said no. I asked Doug if he felt constrained by physics, engineering, human factors medical science, etc. with his projects. This resulted in an interesting and most practical discussion and repose. Doug also coined a great phrase in response to this question, "Physics does not work in Power Point!" Later in the first segment, he talked in detail about large landers and the Centaur upper stage. His PPT shows pictures of his projects and where applicable, he created images to help us along in our understanding. We continued talking about the projects he has already done for the balance of the segment. In the second segment, we finished the discussion of his already done projects but we spent some time on the Gravitron. Here, Doug talked about additional experiments he would like to do revolving around the Graviton but he was not sure that the ride operators would be all that cooperative with him in allowing him and others to do these experiments. It is an interesting discussion, don't miss it. Doug soon turned to his wish list projects which start on slide 11. As before, our discussion tracked the slide number so it is easy to follow along with us. Among the listener questions that he fielded in this segment, one asked him how he knew for sure that there was sufficient water ice on the Moon at the poles or anywhere for that matter. Don't miss his response. Read the rest of the review @ www.thespaceshow.com or http://thespaceshow.wordpress.com Selected by: David Livingston [ stations ], Mon, 14 Sep 2015 19:10:39 UTC

Check it out at www.kickstarter.com/projects/1960236542/clearing-the-roadblock-to-mars. During the first segment of our 1 hour 32 minute show, Rand introduced us to the purpose of this campaign which was to show how much better and wiser NASA could use the funds now being spent on SLS. Or as Rand said throughout our discussion, to get more bang for the buck. Of course this assumes NASA would use the savings wisely. In this segment, Rand spent considerable time addressing the lack of SLS missions, the types of missions SLS might be used for but so far no such SLS missions have been settled on, plus he talked about having more efficiency by using smaller rockets, more launches and fuel depots. He also said we were not serious about space as evidence by the SLS program. Several listeners asked him about the trades between heavy lift and a smaller rocket, the risks involved, costs and more as this is a common debate topic in the industry. Rand said the debate would eventually be settled by market forces. I added in that the characteristics and performance of the rockets being used to settle the heavy lift or not question will also factor into any conclusions reached on this subject. Rand then talked about the Aerojet Rocketdyne announcement that they wanted to acquire ULA for $2 billion. This led to an additional discussion about the Atlas rocket, Russian rocket engines, Vulcan, and Blue Origin. He also answered specific questions about his Kickstarter project which he said was to show how much more could be done wit h the SLS money rather than spending it on SLS. In response to listener questions wanting him to compare SLS to Falcon Heavy, he said about three Falcon Heavy launches would equal one SLS launch. He advocated SpaceX do an Apollo 8 type of flight with the Falcon and Dragon but then said it probably would not happen because of their relationship with NASA. As we started the second segment, Dr. Doug called from S. California to inquire about the technical capability of SLS and Falcon Heavy plus the ULA Vulcan medium to heavy lift rocket. In addition, Rand discussed the reusable Vulcan concept as compared to the SpaceX concept of landing on a barge. Rand was asked about the need for heavy lift for Mars. He made it clear he was not interested in Mars per se, instead, he wanted to lower the cost of space access to make it possible for anyone to go anywhere in the solar system, including Mars. Rand said over and over again that he was destination agnostic. Read the rest of the summary @ www.thespaceshow.com or http://thespaceshow.wordpress.com.
