During our discussion, Dr. Woodward mentioned his book, "Making Starships and Stargates which you can order at http://ssi.org/exotic-propulsion-initiative as this allows SSI to get a royalty payment on the sale of the book. If you buy the book through Amazon using TSS/OGLF portal, The Space Show gets a percentage of the sales price of the book. In addition, the Charles Platt article, "Strange thrust: the unproven science that could propel our children into space" can be found here: http://boingboing.net/2014/11/24/the-quest-for-a-reactionless-s.html. Finally, Dr. Woodward mentioned the paper written by Dr. Heidi Fearn, "New Theoretical Results for the Mach Effect Thruster." You can download this paper at www.researchgate.net/publication/280134421_New_Theoretical_Results_for_the_Mach_Effect_Thruster. Note that in the final minutes of our program, Dr. Woodward spoke very softly and we were unable to get some of what he said as part of his final comments. While the 1 hour 56 minute program was divided into two segments, this summary will be in one segment only and short as the papers above tell the story. I urge you to read them and become familiar with Dr. Woodward's work either before or after listening to this discussion which was at times very technical and heavy in the theoretical physics fields for gravitational forces, electromagnetic forces and more as he described the Mach Effect. In addition to the physics, since Dr. Woodward's work is dependent on funding so he spent a good amount of time in both segments answering questions and telling us what it was like trying to get funding, approved proposals, etc. for cutting edge work or even work considered to be out of the box or on the fringe. His realistic assessment of the challenges posed by his and similar work goes to the point of why we don't see more out of the box science & advanced projects being financed. In addition to the physics and funding discussions, we talked timelines for his having commercial uses for small Mach thrusters which would start off servicing satellites. This discussion covered both segments. Please post your comments/questions on TSS blog above. You can contact Dr. Woodward through me at drspace@thespaceshow.com or his Cal State Fullerton website.

This will help me bring better programming to the audience. We welcomed Dr. Jack Burns to the program to discuss lunar policy, public and commercial missions, the international momentum for going to the Moon and more. During the first segment of the 1 hour 23 minute show, Dr. Burns responded to my initial question as to why we have not returned to the Moon since Apollo ended. He provided us with a comprehensive overview going back to the Cold War period, our technology readiness level at the time, the costs involved in going to the Moon, and much more. He also talked about the unique drivers at the time for space, drivers which don't exist today. We then discussed today's drivers for both public and private/commercial programs along with today's economic and technology readiness level. Don't miss his analysis. Dr. Burns did say (several times during our discussion) that international support for lunar missions, both robotic and human, was growing. He also referred to The Global Exploration Roadmap (www.nasa.gov/pdf/591067main_GER_2011_small_single.pdf) several times during the discussion. Later, lunar exploration was discussed and Dr. Burns talked about scientific drivers and the stepping stone concept. He said the Moon was a crucial stepping stone to other solar system projects and destinations. Listener Jerry sent in a note based on the YouTube video of our guest about using the Moon for the exploration of the cosmos (https://www.youtube.com/watch?v=8BrhYOaAkko). Dr. Burns took time to describe his DARE project (The Dark Ages Radio Explorer). For information on this project, see http://lunar.colorado.edu/dare/mission.html. Listeners asked our guest to explain why the lunar farside was so good for communication and various arrays. Don't miss his explanation. Later in the segment we talked about cislunar space, Orion missions, timelines, and even lunar communication latency. We also talked about Mars missions and at one point our guest said going to Mars without first learning things on the Moon increases risk for the mission and those going to Mars. Doug called with a series of comments, then BJohn asked why lunar landings were so rare (from his perspective). In the second segment, Catherine asked Dr. Burns for his top three science missions and commercial mission were he in charge of lunar policy. After Dr. Burns responded to Catherine's question, Connie wanted to know about new theories on how the Moon was created. BJohn asked about the launcher selected for the DARE project plus other lunar related propulsion and primary/secondary payload requirements. I asked Jack about the use of cubesats in lunar missions and just how it important was it for the general public to support a return to the Moon policy.

This will help me bring better programming to the audience. We welcomed Dr. Doug Plata back as our guest to discuss his paper which is on TSS blog for your perusal, "Achieving Early Earth Independence Through ISRU and Sufficient Supply. During the first segment of our 1 hou 45 minute program, Doug told us the genesis of his ideas and concepts culminating in his submitting his paper to the NASA Challenge InnoCentive Challenge (www.innocentive.com/ar/challenge/9933746). After referencing the NASA Challenge, Doug started describing his ideas in detail. Much of what he described he said was summarized in the Introduction of his paper. We talked about both the Moon and Mars but Doug explained that the competition was focused on Mars so he also focused on Mars though he still supports the Moon and cislunar development as the rational and initial starting points. Issues he discussed included supplies, types of potential habitats, the definition of and clarifications for mass independence including defining both self-sufficient and self-sustaining. He also brought up the earth return option and more. BJohn sent in several questions but his initial one asking about becoming 90% Earth independent led to a most interesting discussion. While Doug's paper does not have page numbers, check out Table 3, "Estimated Equivalent Mass Independence. Doug took us through the critical numbers and his analysis so don't miss this important discussion. In the second segment, Doug suggested three rationales for the settlement. One was to push technologies needed for sustainable living in space. The second was the big one according to his perspective and focused on reducing the resupply costs for the settlement. The third one was also big and focused on assuring survival of the human species. He discussed each rational in detail. As part of the discussion, he referenced a space settlement as an insurance policy for humans, he talked about the earth return option, radiation, GCRs, and more. He also showed that by leaving the crew on Mars for an extra year, the mission would be less costly. Listen to his discussion about this and see if you concur with him. Doug was asked about the previous program with Al Globus and LEO settlements, especially over the equator. He said that such settlements, while potentially interesting, cannot be self-sufficient or Earth independent and his focus was on gaining Earth independence. Again, don't miss this discussion. Gravity, artificial gravity and spin rates were discussed as was the concept of self-sustaining versus self-sufficient for a colony. Doug advocated for using the word colony rather than settlement but I took issue with that, especially if one hopes to communicate with people including Congress outside the space industry.

Al Globus, Sunday, 7-12-15 (60.06MB; download) -- Guest: Al Globus; Topics: Space settlement in LEO and radiation over the equator. 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.

For those listening to archives using live365.com and rating the programs, please email me as to why you assign a specific rating to the show. This will help me bring better programming to the audience. We welcomed back Al Globus to discuss his plan for LEO space settlement about 500 km above the equator to minimize radiation, shielding, and to improve the mass ratios to make settlement easier than in other locations. During the first segment of our 1 hour 49 minute program, Al put forth his hypothesis that radiation over the equator was very light meaning that any space settlement would need minimal shielding or possibly no shielding. This vastly improved the economics of developing and resupplying the settlement given its close proximity to Earth and the lower mass needed for the settlement and transportation. This would be a "free space settlement" meaning it would be in orbit. During this segment and the entire program, Al explained the radiation issues but you should read his paper on the subject, "Space Settlement the Easy Way." You can find this paper at http://space.alglobus.net/presentations/Easy.pdf. Al spent lots of time explaining the radiation issues and talking about the initial settlements which may not have an economic purpose. Al did go into the technical side of the radiation issues and his analysis for this location so don't miss what he had to say about it plus as I suggested above, be sure to read his paper. Later in the segment, he brought up space tourism and space hotels as a type of initial space settlement but one that would pave the way for actual settlements in LEO. In the end, Al said that a LEO settlement is an easier way to get started with space settlement but stated many times that even a LEO space settlement above the equator would be challenging. He did get several listener emails, some of which challenged his radiation analysis and the idea that little or no shielding would be necessary. Al was also asked about space exploration but he was very clear that he was focused on space settlement. In the second segment, we talked space policy, the U.S. congress and even the issue of space debris removal. Marshal called to talk about radiation shelters from solar storms, Alexander wanted to know more about space solar power. Adrian sent in a series of notes challenging Al and using the December 2004 Magnetar event. Al was not familiar with it. I inquired of the listeners to tell us what happened to the ISS during the event. After the show, I got a follow up note from Adrian regarding the event and the ISS: "Thanks to the magnetar's great distance, the super flare posed no threat to humanity or Earth's biosphere. The International Space Station was on the opposite side of Earth when the flare hit our planet, but even if the astronauts had faced the full fury of the blast, they would have received a radiation dose less than a dental X-ray.

For those listening to archives using live365.com and rating the programs, please email me as to why you assign a specific rating to the show. This will help me bring better programming to the audience. We welcomes Dr. Robert Kooima to the program to discuss his 3D imaging and software work, especially for the Moon and planetary bodies. Visit his website and www.kooima.net, then click on Applications, then click on Panoptic. This will enable you to follow along with our discussion. In the first segment of our 1 hour 22 minute program, Dr. Kooima started out by telling us how he developed the software he uses for his 3D renderings and images. Note that the software is freely downloadable from his website on the Panoptic page. Also, its Open Source and Dr. Kooima is interested in your feedback if you use it. His email address is on most pages of his website. Keep in mind if you do download the software, you still have to download the database & those are very large files as you will hear toward the end of the first segment. Dr. Kooima shared with us his motivation for doing this, then he explained the pixels and resolution and why the object needed to be spherical. Our guest was asked about side effects using 3D including Oculus Rift and here, our guest had much to say, plus he explained many of the problems by helping us to understand human brain perception. Listeners asked about computer power and faster speeds, latency and rover motion. In the second segment, our guest told us about his YouTube channel and how to find it. He suggested we watch the "LRO & The Real Time 3D video as well as the "Tour of the Moon on the Oculus Rift." BJohn wanted to know about the ability to image irregularly shaped objects such as Comet 67P. Be sure to listen to what Robert said about this. Other listeners wanted to know the ease of rendering 3D from the Moon or Mars, then someone asked about using all the radar and other data to create a 3D image of the surface of Venus through the clouds. Our guest talked about the complexities of atmospheric rendering and the fact that Moon had much more data available so it was by far the easiest to render. Dr. Kooima then brought up issues revolving the focus of an object as this is very important to the imaging. Another listener wanted to know if the path to this work was through computer science and graphics or astronomy. You might be surprised by his answer. Our guest also mentioned other software available including the USGS Isis Planetary Image Processing Software and the Celestia Planetary Software. near the end, I asked or guest where this field might be in ten years from now. Don't miss what e said about the future, the time table, even the investment. Don't miss his closing comments. Please post your questions/comments on TSS blog above. You can reach our guest through his email address which is on most pages of his website. Selected by: David Livingston [ stations ], Sat, 11 Jul 2015 17:23:38 UTC

Dr. Charles Limoli, Tuesday, 7-7-15 (46.78MB; download) -- Guest: Dr. Charles Limoli. Topics: We discussed space radiation in the context of his paper, "What Happens To Your Brain On The Way 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.

For those listening to archives using live365.com and rating the programs, please email me as to why you assign a specific rating to the show. This will help me bring better programming to the audience. We welcomed Dr. Charles Limoli to the program for this 90 minute discussion on space radiation and astronauts, especially flying in deep space, going to Mars or back to the Moon, evening residing on the Moon or Mars. You can read his paper which has been uploaded to The Space Show blog for this program. During the first segment, Dr. Limoli outlined the basics of his research. Before going deeper into the topic, I asked him several questions about the use of rodents and mice for the experiments, the possible use of other animals, the constraints and limitations of radiation simulation experiments, plus how these radiation experiments and doses differ from humans getting radiation treatment for cancer or other medical problems. We had quite the discussion on rodent brains compared to human brains, animal experiments in general, plus the protocols used in his experiments which were all carried out at Brookhaven. By the way, Dr. Limoli is a space advocate, he has received NASA funding for years, and he and his team have a great interest in radiation issues for human spaceflight. Dr. Limoli then took time to tell us how the experiments were conducted. Some of the discussion is technical so I suggest you read his paper which has been placed on TSS blog. Dr. Limoli went into significant detail to tell us how they conducted the experiments, applied the low dose radiation to the subjects, and how they evaluated the results. Don't miss his description and analysis of the experiments. He said the changes were subtle measured 6-8 weeks out but he also said future papers may show that the cognitive changes continued to happen over a much longer period of time. In response to one of my questions, he said there was no sign of recovery. The primary changes that were observed and reported in the paper had to do with cognitive impairment which we discussed in detail throughout this program. I asked our guest about age, gender, race, and cultural differences. I also asked if NASA was now doing or might do in the future some genetic screening to find those best suited for a high radiation environment. Space settlement risks were talked about as was childbirth and pregnancy. Dr. Doug from S. California called to talk about GCR shielding. He wanted to inquire about using the stuff on the mission, food, water, supplies, etc. for shielding. He suggested the strategic placement of the stuff to maximize shielding. Dr. Limoli did say this was all factored in but that GCRs are non-directional so they come in from everywhere so such "stuff" shielding would only be partially helpful in protecting against radiation.

This will help me bring better programming to the audience. We welcomed Jim Muncy back to the program to discuss current space policy and budget issues before the U.S. Congress, company updates, and much more. During the first segment of our 1 hour 50 minute discussion, Jim provided us with the groundwork for most of our discussion by going back to the Commercial Space Launch Act of 1984, then the update to it known as the Commercial Space Launch Amendments Act of 2004. He talked about both the House and Senate versions of the NASA and space budget bills and some of the differences between the two bills. One difference which he explained in detail early in the second segment had to do with the learning period which is important for the developing industry. Another difference between the two revolved around extending the ISS commitment to 2024 plus issues relating to BLEO space. When asked if he thought the final bill would be signed or vetoed by the president, he said it was nonpartisan and he did not see problems getting it signed into law. Listeners asked about funding SLS. Much was said about SLS in both segments but one listener asked Jim why so many supported SLS given its shortcomings. Jim explained the mindset of many SLS supporters in congress. As you will hear, SLS is hardly a black or white issue. This discussion led to a related discussion on developing a new rocket engine, the issues involved, the competitors, methane versus other fuel, and more. In particular, he used Alabama Congressman Mike Rogers as an example supporting is analysis of the situation. Jim was asked about the impact of the Falcon 9 failure which led him to address the need for multiple launchers and competition. Later, Alex asked him about his areas of concern regarding the pending budget legislation. He talked about sequestration, spending caps, delays, and the problem with operating on a CR which is likely. This is a lengthy but important discussion so don't miss it. Before the segment ended, Jim was asked about the lunar lander. Jim then talked about the Flexible Path, Google Lunar XPrize, cislunar space development and Mars. Jim advocated the need for public private partnerships, then he was asked about international partnerships. In the second segment, we started with an email question from Doug inquiring about the Augustine Commission presenting an option for returning to the Moon with landers developed in a public-private program context. After Jim's response, I asked him to refer back to a comment he made in the first segment and to explain what was meant by the learning period. This was an important discussion so don't miss it. As part of his response, he also provided a short overview of the suborbital industry and participants plus the orbital industry.

John Batchelor and I welcomed back space attorney Michael Listner to the program to discuss the significance of the U.S. National Space Policy. We talked about some of the choices the next administration might have in formulating a new national space policy including the continuation of subsidies to the commercial space industry, to finally take up space debris removal policy for U.S. debris, and even to start formulating policy on space property rights. Michael also discussed the trend toward transparency and confidence building measures which are a product of the Executive Branch as compared to treaties which need approval from the Senate. I asked Michael if he thought we might start seeing policy emerge as to the usage of cubesats plus I asked how human spaceflight might be impacted by a new national space policy. Please post comments and questions on The Space Show blog, http://thespaceshow.wordpress.com. You can email Mr. Batchelor or Michael Listner through me at drspace@thespaceshow.com.

Dr. Clark Lindsey, Tuesday, 6-30-15 (56.26MB; download) -- Guest: Dr. Clark Lindsey. Topics: We reviewed current issues and happenings across the full spectrum of the space industry. 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.

For those listening to archives using live365.com and rating the programs, please email me as to why you assign a specific rating to the show. This will help me bring better programming to the audience. We welcomed Dr. Clark Lindsey back to the program for a wide ranging discussion on space industry news and issues. During the first segment of our 1 hour 47 minute program, Clark started out by talking about the changes over the years in the small satellite industry. He referenced several companies making news such as One World, Spire, Planet Labs, Skybox, Rocket Lab, Firefly, plus others. This brought him to an interesting cubesat discussion. Next up was the Falcon 9 launch failure from a few days ago. He did not have any new information and we are all still waiting for the cause of the mishap to be stated. He did clarify some of the confusion around the Air Force having sent a destruct signal to the Falcon 9. He said such a signal was sent but about 90 seconds after the event. We then talked about other rocket launch failures in the early days of the Arianne, Atlas & Delta history. Clark was asked about policy issues surrounding the RD-180 engine buy, Senator McCain, commercial crew, and congressional leanings at this point in time. Listeners asked him if he thought SpaceX was seriously hurt by the Falcon 9 accident. He said he thought the company was definitely wounded but it was too early to determine how badly the wound might be. He mentioned the Google billion dollar investment in SpaceX, their commercial manifest and more. Joe in Dallas wanted to know how he thought the Falcon Heavy schedule might be altered as a result of the launch failure. Clark talked about other work being carried out by SpaceX plus he offered some ideas on how testing of any new Falcon 9 systems might be integrated into testing other SpaceX projects including the Falcon Heavy. Jack in Boston wanted to know if Clark had any information on Virgin Galactic. Clark talked about XCOR in his answer and said the companies would likely be adopting a very slow go time table to assure no further mishaps. In the second segment, we started discussing Clark's slide presentation on the satellite industry per his talk at Space Access 2015. You can find these slides on The Space Show blog post for this program as I uploaded them to the blog with Clark's permission.
