We welcomed Patrick (Pat) Host to the program to discuss national security, defense, and military space. We started our 1 hour 47 minute discussion with a first segment that focused on the RD180 issue. While we have talked about it before, Pat provided us a different perspective for this thorough discussion which also went into civil space and issues over competition. You do not want to miss this discussion. Pat also talked about the main players on both sides driving the RD180 issue. Another topic covered in the first segment focused on protecting our existing space assets, including cyber issues and essential cyber protection. Our guest had much to say on this topic, including DoD priorities. Several listener email questions came in. Ben from Boston wanted to know about national security launches and SpaceX. Our guest supported multiple launch providers but listen to his comments for detail. Another listener asked about DOD and the potential threats posed by Iran and N. Korea. Unfortunately, our guest was not able to offer us much on this topic. For the second segment, note that there was an editing glitch as the segment started. I did pick up on the glitch quickly but could not restore the first few minutes. However, when I realized what had happened, I asked Pat the initial question over again so you did not miss anything despite the glitch. My apologies for this as the mistake was on me. That said, we started the second segment with Pat telling us about Rep. Jim Bridenstine from Oklahoma wanting more accountability for DOD and more. Our guest referenced the American Space Renaissance Act. Read about the Act which was introduced at the recent Space Foundation Conference in April at Colorado Springs, http://bridenstine.house.gov/space/?postid=710. I urge you to become familiar with this proposed legislation which covers national security, civil, commercial, and military space issues. I'm sure we will hear much more about it as time goes on. Satellite communication issues were discussed in this segment as they are very important and key for national security space and the Air Force. Pat did a good job of putting these issues in focus for us, helping to understand them and their importance. Richard Easton called to talk GPS OCS and GPS 3. This was a good exchange, don't miss it. Next, Pat introduced us to the issue of what to do with excess ICBM motors. DOD has kept retired ICBM motors in good condition and Orbital ATK wants DOD to sell them for commercial use,. This is very controversial with most commercial launch companies opposing the idea. Pat explained the issue to us, the role of Congress as congressional approval would be required to sell them. I also asked him what the success rate might be for using these retired engines. That remains an unknown but there is an expected failure rate with them. Burton from Montreal sent in two emails asking about DOD launches requiring bigger rockets than a Delta IV Hea Selected by: David Livingston [ stations ], Wed, 04 May 2016 15:31:43 UTC

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed back to the show Dr. Dan Durda to update us on commercial suborbital science research and space adventure (tourism) flights. During the first segment of our 90 minute program, Dr. Durda first talked about the Southwest Research Institute (SwRI) BORE microgravity payload experiment which recently flew aboard Blue Origin's New Shepard space vehicle April 2, 2016. The BORE experiment, otherwise known as the Box of Rocks Experiment, was explained by Dr. Durda plus you can read about it at this SwRI web page: www.swri.org/9what/releases/2016/bore-microgravity-payload.htm#.Vyi3OTf2ZD8. In learning about BORE, I asked how much zero g time the experiment had and what was typical for a commercial suborbital flight. His answer might just surprise you. Dr. Durda then addressed suborbital flight with Virgin Galactic, XCOR, and Blue Origin. Several listeners wanted to know when each company would go operational with their flights. Another listener wanted to know the approximate mix for science and tourism flights. Then later in the segment we talked about other experiments, Saffire-1 and Strata-1. If you Google those two terms, you can find the NASA websites for the two projects. Before the first segment ended, Helen asked if our guest was caught off guard by the advanced Blue Origin condition as exampled by their accomplishing reusability and then flying their rocket over again. Helen said that since Blue was not that public in their announcements lots of people were caught off guard by outstanding Blue achievements. Don't miss what our guest said about this but for the most part, he suggested that since they were working with the company, they had a good idea of just how advanced they were with their flight programs. In the second segment, we talked about the potential of simple life on small asteroid like o objects. When asked what he meant by life, he said "geologic" life. Listen to his explanation. We then talked about exoplanets, finding some that are in their star's habitable zone, then how we study those items plus what we can learn about them. In the context of this discussion, we talked about the use of different kinds of telescopes, including the upcoming JWST. Listener John sent in a note about the recent show with Dr. Seedhouse plus his upcoming book on XCOR. Our guest was very familiar with Dr. Seedhouse and his work. I also asked about the possible revenue mix between space tourism revenue as compared to science revenue. Our guest provided a comprehensive answer to this specific set of questions but based on what is known so far. Thus, about all one can do at this point is speculate. Another topic was the competition among SpaceX, Blue Origin, and Virgin Galactic. Dan had much to say about this competition and importantly, how it might change in the future as the commercial revenue starts to flow. This topic was a result of my asking if he thought all the suborbital companies would survive o Selected by: David Livingston [ stations ], Tue, 03 May 2016 15:08:23 UTC

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed back to the show Dr. Paul Spudis for a discussion about his new book, "The Value of the Moon: How to Explore, Live, and Prosper in Space Using the Moon's Resources," plus Dr. Spudis responded to many listener questions about returning to the Moon, going to Mars, and U.S. space policy. In the first segment of our 1 hour 45 minute discussion, Dr. Spudis introduced us to his new book, then I asked him to elaborate on his chapter that provided three reasons for our going back to the Moon. Paul went over the three reasons so let us know with a blog comment what you think of them. I do! I asked our guest why it has been so challenging to return to the Moon. You do not want to miss what Dr. Spudis said in response to my question. Listener emails started coming in with Karen asking why not first solve our economic problems before going into space or returning to the Moon. Dr. Spudis gave her a good answer, showing how important space has become to all of us. Listeners wanted to know the Spudis roadmap for returning to the Moon so our guest summarized it on air but for all of it, get a copy of his book as that is where the details are located. Listener John wanted to know about public private partnerships, could the Moon be developed totally by the private sector, or would it be developed by only the government. Again, don't miss what our guest had to say in response to this question. Another topic in this segment was Mars and going there as our priority. Dr. Spudis had much to say about going to Mars, using the Moon as a learning and testing base and being the only rational way to have human spaceflight to Mars. Mars was a major part of our discussion as it is a popular target for lots of people regarding spaceflight. We talked about SLS & Orion, , using the big rocket and capsule for going to the Moon, not Mars, and the need for a lunar lander. Dr. Spudis also talked about the important role of robots in returning to the Moon. In the second segment, Judith from Seattle asked what Paul thought of one way trips to the Moon, similar to what Mars One was planning for Mars. He did not think much of them but listen to all of what he had to say about a one way lunar mission. Cislunar transportation was discussed in some detail in this segment. So was the possibility of a lunar space elevator and the changing of US space policy to make space settlement a priority. In this context, our guest had much to say about ISRU.. Next up was an email from Luis in Venezuela asking about solar electric power (SEP). SLS John called to be supportive of Paul's comments about SLS being a placeholder for American labor, skills, and technology. Please read the rest of this summary @ www.thespaceshow.com.

We welcomed back Dr. Stuart Robbins for a space science discussion that addressed many topics and interests. During the first segment of our 96 minute program, Dr. Robbins talked about the recent gravitational waves discovery, then he talked about New Horizons and the incoming Pluto data. We talked about Pluto's status as a planet or a dwarf planet. Listeners asked several Pluto related questions. One thing our guest said was the surprise in finding Pluto to be so active. Dr. Robbins talked about the wide differences in age dating for Pluto ranging from 74 billions years for some surface and other features to just 1 billion years old. He said there was no explanation for this as of yet. At one point I asked him if a fleet of astronauts on the surface of Pluto could do faster and better research than robots of today. Don't miss his answer to this question.
Dr. Robbins has a specialty in studying craters so he was asked if craters were similar throughout the solar system. This was an interesting discussion which included the subject of Halo Craters so don't miss it. Following craters, our guest was asked about Pluto's mythology. He spoke to Pluto being the God of the Underworld. BJohn asked a question about the chaotic rotation of Pluto moons. Johanthon asked about an idea he had regarding the Higgs-Boson particle. In the second segment, Jennifer emailed in a question about some space projects being a waste of money compared to others. This prompted an interesting discussion with our guest, one you will want to hear. This discussion then led to our talking about the private sector doing science missions, returning to the Moon, or partnering with government on a purely science mission. Again, don't miss what Stuart said in response to these questions. Stuart took a listener question inquiring about weird or near crackpot ideas or theories now circulating and in vogue. Our guest talked about the scientific method and the subject of plate tectonics before it became an accepted theory. He pointed out that even when it was a fringe idea, promotors of it went through the publication and presentation format for scientific analysis and verification. As he said, "they played the game." Stuart said that if one is presenting a fringe or out of the box idea or theory, it still needs to go through the process to be taken seriously - most of the time. Listener Johnathon then called the show to ask Dr. Robbins about his theory he presented during the Feb. 28, 2016 Open Lines Show. Stuart could not comment on the theory but pointed to the type of research Johnathan needed to do to have scientists consider it and he suggested several resources for our caller. This included running numbers, examining actual data from Cassini through the PDS (Planetary Data System) and publishing and presenting in more or less official scientific publications and conferences. Publishing ideas on a website or a blog us Selected by: David Livingston [ stations ], Sat, 30 Apr 2016 16:51:20 UTC

John Batchelor and I welcomed Dr. Jim Green, NASA Planetary Science Director, to discuss NASA partnerships with national space agencies with a focus on the Japanese Space Agency (JAXTA). During our double Hotel Mars segment for about 20 minutes, we discussed the Japanese missions Hayabusa, Hayabusa 2, and Akatsuki which is now in orbit around Venus. Some of our questions dealt with the Hayabusa comet visit and sample return, plus the Hayabusa 2 mission now en route to asteroid 1999 JU3. We talked about the way NASA contributed to these missions, ground simulation models for mission problem solving, sample returns, and the art of planetary mission sample return. We also spoke about Akatsuki which after several years is now in orbit around Venus due to years of problem solving for a propulsion problem. Dr. Green explained this methodology to us plus we talked about some of the very early science discoveries regarding Venus given Akatsuki is now orbiting our sister planet. As the segment was ending, Dr. Green mentioned the next JAXTA mission, MMX Martian Moons. NASA is working with JAXTA on this mission as well. You can email Mr. Batchelor or Dr. Green through me at drspace@thespaceshow.com. You can also reach Dr. Green through.

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed Bob Zimmerman back to the program for a discussion of space news events, policies, and programs. Due to a classic Zimmerman rant on Orion-SLS, SpaceX, and the private sector as compared to the public sector, we missed our break timing so this 2 hour 2 minute discussion is in one long segment. For the first hour of the show, besides my regular Space Show announcements, Bob described a report he was writing that details the costs associated with Orion and SLS as compared to what he says the private sector can do, specifically SpaceX. During Bob's rant, Dr. Doug called from S. California to run some numbers through Bob's perspective regarding the NASA Roadmap to Mars plan which focuses on a specific number of SLS launches which Doug converted to Falcon Heavy launches for Bob to consider. Later, Tony sent in a series of questions including one suggesting Elon had said the same first stage could be used for 1,000 launches. Tony cited this video, http://youtu.be/VNygOavo2mY, at the 28 minute mark. Bob quickly dispatched question. One topic I introduced during this part of our conversation focused on the reports that I have been getting from other listeners that Fidelity, the mutual fund company, has invested $100 million in SpaceX, dispersing the investment in several Fidelity funds. I asked questions about how a public registered fund could invest in a private investment. Listen to the discussion and if you have any information on this, we want to hear it. Please post it on The Space Show blog.
John from Ft. Worth called to talk about the SpaceX landing of the first stage on the barge. He also referenced the S&P and some other economic concerns given Bob and I briefly touched on economics during the Zimmerman rant. The question came up as to how SpaceX secures the first stage on the barge to keep it from falling over. Doug and later Mac sent in clarification emails on this process.
For the next part of the show, I forced a change in topics. I asked Bob about the spreading of the bat White Nose Syndrome to the west for the first time. Bob was aware of this and offered us clarifying information. In addition, he let us know why this is important as bats are an important part of our environment. You can read one of the stories about white nose coming west here: http://hostswww.hcn.org/articles/white-nose-syndrome-comes-to-the-west.
Tony asked another question about delays in the development of the Texas SpaceX spaceport. Bob addressed the issues and the soil stabilization plan for the spaceport. Bob then turned his attention to the successes of Blue Origin and what we might expect from them in the near future. He also mentioned Rocket Lab and the development of their small sat launcher. Bob provided us with some short updates on Stratolaunch and the Bigelow BEAM Module now at the ISS. Read the rest of the summary @ www.thespaceshow.com.

We welcomed Michael Patterson to the program to discuss his work on advanced propulsion, mainly electric propulsion (EP). During the first segment of our 1 hour 52 minute show, Michael introduced us to a few challenging rules regarding advanced propulsion. One such rule was that progress usually move at a glacial rate. Another is that space propulsion and power are very expensive. Cost is usually more of a stumbling block than technology and at times, policy. In addition to talking extensively about EP throughout the program, we discussed nuclear propulsion and issues with it. Again, as you will hear, cost controls. We learned that the payoff for doing nuclear ma be suspect. Don't miss all of what Michael had to say on this topic. As for EP, Michael talked quite a bit about both ion thrusters and Hall thrusters, providing us with the advantages and capabilities of each.Our guest had much to say about bringing this technology to commercial markets and several times cited the importance, the value, and the benefits to the commercial U.S. satellite industry by having EP placed on satellites. Other topics in this segment included advanced propulsion for HSF using Mars as an example. Solar electric propulsion was discussed along with improvements in the technology in recent years. Power needs for spacecraft were discussed and contrasted with today's technical capabilities, plus what will be evolving in the near term. Later in this segment, Michael talked about Vasimir. He had much to say about this technology so don't miss this discussion which bled over to the next segment. One of the things he talked about was the inefficiency with Vasimir type propulsion. When asked in the next segment why bother with it then, he had a very powerful response as to why this type of R&D is valuable with a possible high end payoff. Don't miss this Vasimir discussion. Before the segment ended, we talked about advance propulsion in other national space agencies and space-fairing countries. Our guest specifically addressed propulsion in China and Russia.In the second segment, we talked about high powered EP and more on Vasimir. Our guest also provided us with a due diligence method for recognizing more plausible projects. He told us what to look for, to pay attention to efficiency rates, and to question if the physics and engineering is verifiable or out of the box and needing to be verified. Listeners kept asking about other more far out propulsion ideas such as FTL travel, Mach thrusters, Em drive, and more. Michael said that he thought NASA should have a broad view perspective and portfolio but then he talked about costs and making investments in projects that need the physics and engineering to be validated as that is both risky and very costly.

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed Rick Eyerdam to the program to discuss NASA's search for life which was the focus of his new book, "Exobiologists, Rocketeers, and Engineers: Inside NASA'S Quest For Life In Space." During the first segment of our 1 hour 53 minute program, Rick started out with a brief NASA history on the search for life in space. We spent a considerable amount of time talking about Viking 1 and 2, the experiments by Dr. Gil Levin, the instruments used to detect possible life on Mars, the Gas Chromatograph Mass Spectrometer GCMS), plus the history of this search for life from the beginning to current times. In presenting his information to us, we talked about the unique structure of the book, but also Rick said over and over again that all of this was new to NASA and that they were bumbling and stumbling around in this search because they did not know what to do. This was a general theme of the program so be sure to "get it" from Rick early on so you can put his comments in context throughout our discussion.
Other topics discussed in the first segment included methane on Mars, potential geological activity on mars, the Insight Mission, amino acids, organic compounds on Mars, and issues pertaining to Venus, SpaceX plans for Mars, and big rockets. In the second segment, Rick spoke more about Viking and organic chemistry along with the work of Gil Levin. One thing he focused on in both segments was the structure of his book which tells the story of NASA's search for life in space by telling the stories of key people since the dawn of the space age, what they did, and how they did it. Other key stories from important people who have contributed to this search over the past decades were in the book and certainly helped explain how NASA has gone about searching for life in space. The book is a terrific history book with information and stories you won't likely easily find elsewhere.
Rick stressed the importance of finding water on the Moon, Mars and elsewhere in terms of searching for life in space. Many times during our discussion he said to follow the water. Listeners sent in many email questions. For example, Carl wanted to know the cultural impact on us here on Earth for finding life in space. Other listeners asked similar questions of our guest including one religious based question.
Rick told us stories from the major people involved with Viking 1 and 2 and Gil so don't miss these contributions to today's show. Before the show ended, in asking Rick what else he was working on, he mentioned The Tardigrade Project which is explained on his website at http://marsnow.info/tardigradeproject.html. What do you think of this project? Let us know on the blog. Please post your comments/questions in the comments section for this archived show on The Space Show website.

John Batchelor and I welcomed back Dr. Jeff Foust to talk about the recent SpaceX success in landing the first stage on the barge in the Atlantic Ocean. We asked Jeff if there were hard numbers available on the cost and time it takes to refurbish a first stage to get it ready to fly again. We also wanted to know if there was any good information on just how many times a Falcon 9 first stage could be flown. Jeff did not have hard numbers but did say based on the other recovered Falcon 9 first stage that the repairs were minor. John wanted to know if there were plans to land the first stage at the new SpaceX spaceport under construction in Texas and I asked Jeff if SpaceX might be considering licensing their reusable technology given the increasing interest in rocket reusability from other companies. John asked if NASA was interested in reusability. Here, Jeff said no because the one rocket NASA was building, SLS, does not make use of reusability. As the segment was ending, I asked Jeff if there had been any additional SpaceX information made public on starting to introduce reusability to the Falcon 9 second stage. Jeff said it was a long range plan but there was noting going on regarding it at this time far as he knew.

We welcomed Dr. Bruce Cordell back to the show to discuss why he believes we are on the cusp of Maslow Window opening up, setting the stage for a big leap forward with space development and exploration. Our two hour three minute program was in one segment, no break. Also, while processing the program for archives, I accidentally deleted a few short segments which I could not recover. You will probably be able to detect where this happened as the transition cuts reflect the accidental deletes. We started the discussion with Dr. Cordell explaining Maslow Windows, then talking about the JFK (President Kennedy) Moon Mission Program and his policies that produced an economic boom. He said that the Maslow Window materialized over 2-3 years. Bruce talked extensively about the 60s geo political crisis, the Cold War, Soviet Union tensions, conflict and more, drawing some parallels to the global situation today. He even referenced several current news reports saying we were already back in a cold war with Russia and maybe China. Since Dr. Cordell works with trends, he connected the dots to back then and now and sees an opening coming up for a Maslow Window. Bruce talked about various AIAA sessions regarding Mars and other future space plans. He also talked about a possible 2033 Phobos mission and why that made sense. He went back to talking about the aftermath of 1972 and the decades of NASA being in the doldrums. Bruce and I both talked about the very positive impact on the modern space industry of both Elon Musk and SpaceX. He pointed out how they bring a totally different mindset to the game and that is a big part of seeing a Maslow Window open up. Bruce explained the relationship of risk to a Maslow Window along with space industry entrepreneurism. John from Ft. Worth called in citing all the problems and challenges of today, telling Bruce that he did not see anything grandiose in space happening anytime soon. Bruce had a different opinion on what John was saying so don't miss this give and take discussion. Bruce even referenced a recent Wall Street Journal opinion article by economist Martin Feldstein while making his points with John. Dr. Cordell used the term "tipping point" to explain where we are today in terms of the window opening up. Listeners asked him several questions about what was needed for the Maslow Window to appear. For example, listeners wanted to know if America needed to be united. They also wanted to know how dependent the Maslow Window was on having a pro space policy president as a result of the upcoming 2016 election. Listener Carla wanted to know if there was anything advocates could do to facilitate the Maslow Window process. Tim from Huntsville called to ask that if we blow our opportunity, do we get a chance for a do over to open up a Maslow Window. Don't miss how our guest answered Tim's question.
