John Batchelor and I welcomed back Doug Messier of Parabolicarc.com to discuss the NTSB Virgin Galactic accident investigation report. Doug summarized the report for us, addressed key findings mostly directed at Scaled Composites regarding the failure to anticipate pilot and human failure. He also explained the feather mechanism, how its early deployment caused SpaceShip2 to breakup and what the remedy is going to be for SpaceShip2 going forward. John asked Doug about ongoing safety issues with Virgin Galactic, we talked about planned timelines for the renewal of test flights leading to commercial flights, and that many still have doubts regarding the Virgin Galactic operation. Doug was also asked about reports that there was pressure from Branson on AST for experimental permits and cutting oversight corners which many claim allowed an unsafe spaceship to fly.You can email Mr. Batchelor or Doug Messier through me at drspace@thespaceshow.com. Doug can also be reached through his excellent news blog, www.parabolicarc.com.

Follow us at www.lunarinitiatives.com. Russell began the discussion by providing us with the background that led him to create the Lunar Initiatives workshop series. The start goes back to 2009 with the lunar missions that showed there was water ice at the poles. He said this changed the Moon and science for all time and opened up an entirely new realm of lunar possibilities and opportunities. He spent some time discussing the key lunar missions & their significance. Next, we turned our attention to the Lunar Workshops, Lunar Art, and the Lunar Challenges. All are described on his website so check them out. Regarding the workshops, he has a LunarCubes workshop, the Lunar Surface Applications workshop, the Lunar Scientific Opportunities in Cislunar Space (SOCS) workshop, and the Lunar Conference. Read about all of these events on his website but for our discussion, we mostly talked about LunarCubes and cubesats, Cislunar space, and near the end of the show, LunarArt. In addition to discussing The Lunar Initiatives events, Russell talked about returning to the Moon, lunar hackathons, prizes and contests, entrepreneurial efforts to go to the Moon, the Google Lunar XPRIZE, cubesats, the Do It Yourself (DIY) emerging markets, and more. Listeners asked him questions about lunar exploration, the technology readiness level of the entrepreneurs wanting to develop a business for going to the Moon, lunar settlement, lunar habitats, and using the Moon as a stepping stone for other solar system destinations. Don't miss his response to these questions. In the second segment, Russell spent more time on human lunar exploration and settlement and the need to push the technology today to do what we can today rather than waiting to be able to do more in future years. He said the road to the Moon is open! Russell described several existing opportunities including one by Space Systems Loral that you will find interesting. A listener asked him if we needed to focus on developing cislunar transportation, then our conversation switched to Lunar Art and their programs and contests in this area. He said poetry and short stories were included in this category and the contest. Late in the segment, Tim called in to raise questions about settlement given the possibility of gamma ray bursts plus comments from Dr. John Lewis regarding the Moon. Before the show ended, our guest addressed a few more listener emails, then spoke more about the LunarCubes program and website, www.lunarcubes.com. Please post your comments/questions on TSS blog above. You can reach Russell through his website or me. Selected by: David Livingston [ stations ], Wed, 12 Aug 2015 15:28:17 UTC

We welcomed back Jeremy Straub with several of the student participants in this summer's UND undergraduate research program for small spacecraft satellites. Jeremy was joined by Delia, Davila, Wentong Zhang, Samuel Jackson, Alexander Layton, Emily Jenkins, and Matthew Russell. During the first segment of our 82 minute program, Jeremy introduced us to students Samuel Jackson, Matthew Russell, Wanting Zhang & Delia Davila. Each student spent a few minutes going over their research project and interests. I've listed each student & their project in the bio section of this archive program but we did focus on issues dealing with cubesats and higher orbits with the need to deorbit them without causing debris. Neural networks were discussed along with adversarial examples and training problems using a grass and a cow as an example. Don't miss this discussion. Samuel talked about cryptographic algorithms and picture encryption, then Matthew talked about the adaptive attitude control systems for a small satellite or cubesat. He said he was focusing on intrusion detection security for existing satellite security solutions. Jeremy added in details for each of the student research projects and tied the focus to smallsats, especially since all were attending this year's SmallSat Conference in Logan, Utah. In the second segment, Alex Layton led off with his project to find new ways to measure distances with cameras using image processing techniques. He addressed X-Y coordinate issues and more. Emily focused her research on astrodynamics for maintaining orbits and deorbiting small satellites and cubesats from much higher altitudes such as 600 miles above Earth. She had much to say about cubesat orbits today and how they were evolving to higher orbits in a very short period of time. Throughout both segments, Jeremy and the students spoke about various NASA programs and funding opportunities, getting a launch and being placed on a ride share launch manifest. We also had quite the discussion on cybersecurity issues, at times comparing a cyber attack to a physical attack on a satellite. Don't miss what Jeremy had to say on this subject. As our program was nearing the end, we talked about the SmallSat Conference this year, networking opportunities for the students and their future plans. Please post your comments/questions on TSS blog above. You can reach Jeremy Straub through me and any of the students through Jeremy.

We welcomed Spencer Austin-Martin back to the show for the launch of our Indiegogo crowd funding project to modernize The Space Show website and to create a fully searchable and archival quality database for our more than 2,500 Space Show programs. Our Indiegogo campaign launched just before airtime and this was our coming out program for both the campaign and the detailed plans for the new website and archives. Here are the important websites for our campaign: 1. Our support site: www.supportthespaceshow.com; 2. Indiegogo project site: www.indiegogo.com/projects/oglf-and-the-space-show-modernization-campaign; 3. Our YouTube video: www.youtube.com/watch?v=z3DQmpIqi_M&feature=em-upload_owner and our Space Show Facebook page: www.facebook.com/oglfthespaceshow. During the first segment of our 97 minute program, Spencer and I introduced The Space Show website modernization program including the development of a fully searchable and archival quality database. See the links above for our actual crowd funding site on Indiegogo, our Support The Space Show support site, our YouTube video, and our Space Show Facebook fan page. I started off talking about the 501C3 status for our project and what this might mean for you the donor as The Space Show is a nonprofit corporation through One Giant Leap Foundation, Inc. In the early part of our discussion, we talked about having listeners beta test the new website as its developed, plus the Honor Roll for Space Show donors which will be a part of the new website. I also talked about the new Space Show logo designed by my son Jordan. Together with a special autograph, the autograph new logo is the Special Edition Logo that for this campaign only will be on the Perk Space Show gear including the external hard drives. Next, we discussed each of our 17 Perks (incentives), going through each one and explaining the terms or certain issues regarding a specific Perk such as hosting your own Space Show program or webinar. We also talked about domestic and international shipping rates. I went into detail on the host your own Space Show Program perk to let everyone know how such a program would work. I also mentioned that were we to discover really good Space Show hosts, we would develop a substitute host program for future Space Show programs when a substitute host was needed. Spencer and I talked about the logistics for both the Space Show Program Collection Perks using external hard drives to give those wanting their own special collection of Space Show programs and webinars, plus a five year annual subscription to all Space Show programs and webinars.

This will help me bring better programming to the audience. We welcomed Charlie Precourt back to the show to discuss SLS-Orion progress and milestones, human spaceflight, technology advancement, & much more. During our one segment 63 minute discussion, I first asked out guest about the Orbital ATK merger and business under the combined companies. We soon shifted to the SLS-Orion discussion which included information on the 5 segment solid rocket booster (SRB), tonnage to escape which our guest explained, possible missions, and opportunities that will become available as a result of having this heavy lift rocket available for missions that need the lift & high energy capacity of SLS. We talked about shorter travel times, larger payload mass & volume, plus higher energy transfer orbits using SLS as compared to an EELV. Charlies was asked about SRB safety for human spaceflight. Don't miss his comments on this issue. He talked at length about the benefits of marrying the SRB for lift out of a gravity well to liquids for propulsion once in space. Our guest provided statistics on SRB launches and uses to support what he was telling us. Charlie also talked about his Space Shuttle flight experience and the Shuttle's SME, especially when there was an SME problem on one of his shuttle flights. We talked about going BLEO and he introduced us to the concept of One Space. As a result of listener questions, our guest talked about SLS costs, its design for multiple destinations and missions, and the launch "sweet spot" that it would fill. BJohn asked if there were uses for an SRB or solid rocket motor in space. Charlie said for liftoff from a gravity well, yes, but otherwise the SPI for a solid was likely too low for in-space propulsion. I asked our guest about Orbital ATK meeting the SLS -Orion milestones and upcoming flight testing. Jeff from Tucson called in about the use of modern technology including light weight epoxy material for SRBs & other spaceflight hardware. Near the end of the program, I asked Charlie about the justification for HSF to see what he had to say about it. Don't miss his reply. We then talked about technology challenges in going to Mars, choices that were made to do the shuttle and ISS over deep space missions, and destinations that were still Earth dependent as compared to those being Earth independent such as Mars. Jack emailed in a question based on a show earlier in the week where the guest said that for putting SPS infrastructure in space, SLS was too sophisticated. What was needed was big rockets that had a 2% failure rate as that rocket would be lots cheaper than an SLS.

This will help me bring better programming to the audience. We welcomed back to the show Hannah Kerner for this 61 minute discussion about here recent space.com op-ed, "The Space Destination Debate Gets Us Nowhere…Literally." You can read her op-ed at www.space.com/29659-debating-space-destination-is-grounding-exploration.html. Hannah is also the incoming new Executive Director of The Space Frontier Foundation (SFF) so we talked with about her ideas on space advocacy as well as SFF. We started out with a focus on the space destination debate which Hannah said was frustrating, not productive, and helped to create the situation where nobody goes anyplace. She also suggested that regardless of the destination, all space destinations benefit one another. The Stepping Stone Approach was discussed, especially in terms of what makes most sense from both the TRL and economic perspectives. Later in the segment, Hannah talked about the impact of the current go nowhere human spaceflight program on young people or millennials in school and entering the job market. This was a very interesting discussion from the millennial perspective so don't miss it. As an example, our guest compared career options with NASA to those with companies such as Microsoft, Google, Apple, and other tech giants. We talked about their quick turnaround time with projects as compared to really long space projects, maybe up to a decade or more, with the risk of delays and even cancellation. Using the Europa mission as an example, I asked her how that would be viewed by a person in school wanting to do something important but seeing how long it would take plus the risks of delays or even project cancellation. She talked about devoting one's career to a life long project like that and how that might be viewed by today's students and graduates. For the balance of the program, we turned to The Space Frontier Foundation (SFF) and space advocacy in general. Hannah told us about an informal survey SFF conducted at the recent NewSpace Conference asking people how they viewed space players like Russia, China, India, the US, etc., either in terms of tension or innovation. She said 70% of those responding viewed participation by these players as spurring innovation, not adding to national or global tensions. The Linda Billings Scientific American article came up and Hannah gave us a different perspective than we have been hearing. She did not think it was an attack on SFF but rather the author was not that well informed about the Foundation or NewSpace. We then talked about the changes in the Foundation and space advocacy in general, diversity which is improving, the increase of women in the movement, having access to advocacy organizations, ideas, and information.

This will help me bring better programming to the audience. We welcomed Brent Sherwood back to the show to discuss the rational, potential, and economics for the use of space solar power (SSP). During the first segment of our 1 hour 27 minute discussion, Brent first introduced us to Dr. David MacKay from Cambridge University who in 2009 was appointed Chief Scientific Advisor to the Department of Energy and Climate Change. Brent talked about Dr. MacKay's book during our discussion, "Sustainable Energy-Without The Hot Air" which is available for free on the internet. You should follow along in the book with Brent's discussion, especially in the first segment, as our guest referred to pages and visuals frequently. Check it out at http://withouthotair.com. Most of the first segment was spent using information from Professor MacKay's book to explain the current energy and climate situation on Earth and to justifying moving away from petroleum, eventually to SSP. Brent talked about CO2, energy disruption, the transition to something other than fossil fuels, and how to develop SSP. Dr. MacKay used modeling for the UK which Brent referenced, especially from page 215 with the UK map. Brent then talked economics, again referring to the work by Dr. MacKay suggesting an SSP system costing $1.4 trillion! Spread out over a number of years, that price was not much different from what is spent on several government departments and policies, including NASA at this time. Brent listed several examples of this so don't miss this discussion. Brent then suggested the least path of disruption would focus on the key which would have to be electricity. This took us to our next topic which addressed how to generate the amount of electricity needed, including his identifying several newer technologies that could lower some industry costs. He talked about some of the main challenges including transportation, storage, transmission, & operations. Later in the segment, Brent delved into the cost per kWh for electricity. Marshal called to talk about key new technologies including advancements in related and applicable photo voltaics and more. In the much shorter second segment, Brent talked about macro engineering projects and huge platforms in GEO space. He said that such SSP GEO platforms would be around 7,000 sq. km. or three times the size of the paved U.S. national highway surface. Brent then addressed why none of this ever happens and he pointed to this not being a purpose of NASA as an example. To counter this, he advocated for a serious demo project, even suggesting the use of the ISS for the demo. Our guest talked about the challenge in attracting private capital to this because it is so futuristic right now.

This will help me bring better programming to the audience. Welcome to hour two hour twelve minute Open Lines program. In the first segment which was 70 minutes in length, besides throwing out some potential topics of interest, I introduced everyone to Spencer Austin-Martin. Spencer, a Space Show listener, stepped forward earlier this year to help us out with our website problem. Since then, Spencer has designed both our support website for our upcoming Indiegogo crowdfunding project to design and build a new website plus develop a fully searchable and archival quality database. Today we launched our support website, www.supporthespaceshow.com which will compliment our Indiegogo site once we take it public next Sunday, August 9 as Spencer will be with us for the full program that day. Today, Spencer explained the basic plan for the new site, what we can do with our archives, what the benefits will be for you the listener and for researchers. We also talked about some of the specifics of our Indiegogo project & incentives. While the support site is now up and running, it will likely be tweaked a bit before next Sunday. We answered many listener questions about the new site and our campaign Later, the topic of written transcripts for the new site came up for now and the future. I understand this would be a valuable benefit for listeners and researchers but for now there are legal, financial, and other constraints associated with doing this. I spent some time explaining the issues but I did say that the new website and archives will be able to deal with written transcripts down the road if we can find out way to get over constraints, of which there are many. Dr. Doug called to promote his idea regarding key words, we had a heated discussion and we certainly disagreed as Doug would like to see a real time notation available for guest usage of key words. I have asked Doug to post his idea (succinctly I hope) on the blog so that you can fully understand what he would like and so that you can chime in on it, tweak it, love it, hate it, or all of the above. In addition in this segment and the next one, I put out a call for help with voice recognition software that I can use to help me out as I recover from major hand surgery and the lack of use of my right hand for six week, plus for down the road use with transcripts. Listen to my call for help in both segments concerning a need for a quality voice recognition program and if you can suggest one, post it on the blog or email me direct. In the second segment, John from Ft. Worth called to talk about the recent program with Dr. Woodward as he has been reading Dr. Woodward's book on Mach thrusters.

John Batchelor and I welcomed back Dr. Marc Rayman to the show to discuss the latest news coming back from the Dawn Mission regarding dwarf planet Ceres. We talked about the Ceres topography including the bright spots, the haze in crater Occator, the three mile high pyramid peak which may be remnants of a volcano, plus the dust layer over Ceres, ice, and oceans under the ice. Dr. Ryman talked about some of the processes that might have created these characteristics and conditions on Ceres but as you will hear, much is still unexplained. Dawn will make a close pass of Ceres at 900 miles from the surface in early August. Its closest pass will be in December 2015 at about 232 miles above the surface. Check out the new Dawn color coded topography map at http://dawn.jpl.nasa.gov. You can email Mr. Batchelor or Dr. Rayman through me at drspace@thespaceshow.com.
