We welcomed back Rand Simberg and Bill Simon to the show to discuss the importance of July 20, 1969, our having landed on the Moon leaving Earth behind, and their ceremony, Evoloterra (www.evoloterra.com). During the first segment of our 1 hour 26 minute program, Bill and Rand talked about the creation of the Evoloterra ceremony, what it signifies and what it honors. They talked about the importance of storytelling and why they modeled Evoloterra on the Passover Seder. Both guests talked about the importance of leaving Earth’s gravity well for the first time for another planet though later Rand offered a correction to that statement since the Moon orbits Earth and the Apollo crew was always in the sphere of influence of Earth. Rand said going to Mars would be the first time humans will have left the influence of our home planet. This discussion covered a large part of the first segment. Next, we got into space policy and theoretical discussions such as what the world would be like, including US space policy, had the Soviets beat us to the Moon and established a permanent lunar base there. Both our guests offered speculative views of alternative time lines & realities had something like that actually happened. Getting into the Evoloterra relevance today, Rand took the lead and had much to say about our current space policy, how we should be doing things and why we should not be trying to recreate Apollo. In addition, our guests talked about going to Mars and at one point it was said that there was probably no path to Mars without going through the Moon. We talked about the press conference today announcing the new Return to the Moon plan. You can download and read the plan at www.scribd.com/doc/272096719/NexGen-report-on-leveraging-commercial-rockets-to-return-to-the-moon. Rand had interesting comments about it though given it had just come out a few hours before our show today, none of us had yet read the 100 page plus report. However, It will be the subject of our next Open Lines show. Rand made several points that doing great things in space did not have to come about due to a policy based on war, referring to Apollo and the Cold War. Skipping over to the second segment, we talked about previous reports regarding space policy and Rand noted that these earlier reports did not advocate a national policy for space settlement. We then discussed space settlement for a good part of this segment, with our guests explaining why it should be our national policy. For future missions, Rand kept saying they did not have to be based on battles and wars. Bill said we needed the challenges & to win. Several catalyst type events were mentioned including asteroid threats. Rand talked about addressing many issues including space mining, property rights and affordability. Both guests offered excellent closing comments, don’t miss them. Post your comments/questions on TSS blog above. You can reach Rand and Bill through me at drspace@thespaceshow.com.

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. Doug called to take issue with the missions Dr. Burns preferred because they would essentially eat up the budget leaving little or nothing for missions that Doug preferred. This led to a budget and choice discussion, then I chimed in with a minor rant from an economic perspective about using public money better so we did not have to make choices regarding this or that mission or project. I ranted on about the difference in an expense and investment at the federal level. I admitted to this being my space cadet fantasy as I know we are not headed for economic deployment as I wished for in my comments. Don’t miss the final questions of the program and the concluding comments offered by Dr. Burns.

We welcomed back to the show Dr. John Logsdon to discuss his new book, “After Apollo? Richard Nixon and the American Space Program.” During the first segment of our 90 minute discussion, Dr. Logsdon provided us with the multi-year history behind his researching and writing this book. We talked about the Space Shuttle but also the gap within NASA and parts of the space community including the advocate community between having great expectations but insufficient resources to support the great expectations. We talked about the likelihood of significant NASA budget increases in coming years and while possible, our guest said it was unlikely. President Nixon wanted space to be considered routine and NASA to compete for funding with other parts of the discretionary budget. What President Nixon set in motion is continuing through this day. Dr. Logsdon said policy normally comes from the White House but recently policy for SLS came from the Senate because they did not like what President Obama was doing. We talked about the long range impact of the Nixon space policy even through today and at one point Dr. Logsdon suggested that maybe Nixon got it right regarding American public sentiment about space. Our guest received questions about planetary science and its accomplishments and other listeners inquired about public/private partnerships. Still, our guest said that only governments really have the resources to carry out the type of space investment needed for exploration. Listeners asked about other forces of the time including the Cold War and space policy champions in leadership positions such as Tom Paine who was the NASA Administrator. Dr. Logsdon was asked how things might have been different had Hubert Humphry been elected president. Mars was also discussed, then Dr. Logsdon talked about the space shuttle history. In response to several questions, he shared his thoughts and experiences from his time spent serving on the CAIB. Another topic in this segment dealt with space advocacy. Our guest said we need advocacy to keep the dream alive until leadership makes it happen. He said talk about settlement and pioneering were mainly just words. Pioneering needed to answer two questions which he addressed before the break.

In segment two, we talked about the ISS and Shuttle having consumed the HSF budget and now the ISS does that with about $3 billion per year. Using the shuttle for national defense and security during the Nixon years was also a discussion topic as Nixon liked national security issues. Dr. Logsdon had much to say about the shuttle’s use by the military and for national security. You might be surprised by what you hear. As for human spaceflight, Dr. Logsdon referred her to the NRC Pathways Study which we have discussed many times on The Space Show. More questions came in regarding space advocacy which he said pushes the boundaries of realism and needs to be balanced between sober reality and pure fantasy. Tony emailed us to ask about SLS/Orion, private space over NASA, and Elon Musk and his Mars settlement plans. A question came in about being motivated by the Chinese space program. For closing remarks, Dr. Logsdon addressed the Nixon space policy and program legacy which still influences us today.

Please post your comments/questions on TSS blog above. You can reach Dr. Logsdon through me. When purchasing his book through Amazon, please use the OGLF Amazon link on the website and all archive programs as Amazon will then contribute a percentage of the sale price to The Space Show. Thank you.

We welcomed Dr. Asif Siddiqi to the show.  During the first segment of our 1 hour 53 minute program, Dr. Siddiqi started out with my question about what was going on with space in 1946, the year I was born.  He talked about the early days of space programs from the war, the Soviet Union and the US.  We soon jumped forward to 1969, NASA, Apollo, the Moon, and how many of us from that era thought we were “entitled” to move forward in space to Mars and more.  Our guest had much to say about this space entitlement culture, expectations, and the realities of the time.  We talked about making giant leaps forward rather than a step by step evolving process of moving forward.  Listeners asked him who got the better deal after WW2 with the German rocket scientists, the Soviet Union or the US?  This opened the door to an extensive discussion about Dr. Wernher von Braun.  Asif talked about robotic exploration and the excellent work other space nations and agencies were doing in this field.  John in Ft. Worth called in talked about the impact of the failures of the Soviet Moon Rocket, the N-1.  Our guest and John also talked about the impact of not having competition in the Moon program and how that may have negatively influenced our space program going forward.  Dwayne called and we talked about many topics including the recently concluded Pioneering Space National Summit held in Washington, DC this past week to Mars One, the German rocket scientists after WW2, Arthur Rudolph and Karel Bossart of Atlas rocket fame.

In our second segment, John in Florida called to talk about the conspiracy theory that says the Germans purposely slowed progress on rockets.  This was refuted for other reasons that caused some delays in our program and Russian launching Sputnik before we launched our first satellite.  Next, we turned our attention to the Indian space program which is ambitious but Asif suggested that for now it may be exceeding its capabilities.  Our guest noted they were starting a human spaceflight program and that India was concerned with China and possibly competing with them in space.  The Indian military space program was mentioned as well.  Marshall called and talked about Elon and SpaceX.  Asif had some important things to say about SpaceX, commercial space and government programs.  As we were approaching the end of our program, I asked him what he thought the space history would reflect if written in 2025 for the past decade, the time from now to 2025.  Dr. Siddiqi said it was hard to look forward but he thought some form of Orion would be flying, was not sure about SLS given the proposed low flight rate and suggested ARM won’t happen.  He mentioned many other possibilities for this theoretical ten year time period .   Dwayne called back to comment on Asif’s earlier comments about corporate space programs and policies.  Asif mentioned books and subjects that he liked to review for historical purposes plus he said new historical documents were in such different formats than earlier documents he was not sure how this might influence or impact the work of future historians.  As the show ended, I asked him if thought the Moon would be as hard to return to as going to Mars might be for humans.  He said no because the barriers for going back to the Moon were low compared to Mars and other destinations.

We welcomed Dennis Wingo back to the show to discuss his outstanding article, “The Quagmire of The Apollo Space Program” (see https://denniswingo.wordpress.com/2015/01/18/the-quagmire-of-the-apollo-space-program).  During the first segment of our 1 hour 58 minute discussion, Dennis started out by telling us about his interest in the subject and why he decided to research and write the article in question.  He methodically took us through many of his resources and research methods, highlighting a few resources along the way that were instrumental in his analysis and coming to his conclusions.  One resource he discussed was Ralph Cordiner, the former General Electric CEO.  He also cited many examples in support of his conclusions so I strongly urge you to read his article in association with listening to this program.  He also cited the references indicating that entrepreneurial activity was not what they wanted to happen as an outgrowth of Apollo as it was meant to be a national prestige program.  Given the dysfunction with government, Doug emailed in asking about public/private partnerships.  Dennis offered qualified support for them but listen to what he had to say on this hybrid model.  Dennis then talked about R&D tax credits but for start-ups, the Zero G Zero Tax program was better.  Much of our ongoing discussion in both segments focused on aspects of the Zero G Zero Tax concept.  Doug sent in several emails asking about Zero G Zero Tax before the segment ended.

In the second segment, Charles Lurio called and wanted to know if Pro Space or any organization would be pushing for Zero G Zero Tax this year.  Dennis did not think so but it might happen.  In response to other questions, Dennis explained how Zero G Zero Tax might work because it would only be applicable for new businesses, not existing businesses.  Don’t miss this explanation.  Later, Doug asked if we were running out of resources on Earth that might cause a need for space resource development.  Dennis had much to say on this, especially regarding rare earth elements.  This prompted a call from Kristophr about thorium as a reason the US does not develop its huge rare earth element resources while China does develop theirs plus they stockpile the thorium for future use.  Dennis and Kristophr had a very interesting conversation about this topic and I assure you, you do not want to miss it.  As the segment advanced, Dennis spoke to the commercial opportunities arising from the ISS which he said were very important.  SLS came up and he said it was a done deal but that the key was to focus on what was good and could be built by private enterprise to economically develop the solar system which should be the goal.  To this end, we talked about the need for a transportation system, cislunar development, the asteroids, etc.  In his summary comments, Dennis said that for the bottom line, there were lots of positive things going on at this time.  He spoke to free people and private enterprise leading the way to the economic development of the solar system.  I believe his closing comments spoke to the interests of almost all of us listening to The Space Show.

 We welcomed Dr. Andrew Rader to the show to discuss his aerospace engineering lectures and other material on his website, http://www.andrew-rader.com as well as his YouTube channel.  You can access all his material, his YouTube channel and his book through his website.  During our one segment one hour discussion, Andrew talked about his Mars cooking video regarding his eating bugs.  We had quite the discussion about this.  Crickets anyone?  Next, we talked about going to Mars and he introduced us to his YouTube channel which has 74 videos and more on it.  His aerospace engineering class lectures are there too and very popular with students, especially those wanting to see if aerospace engineering might be the path for their studies.   Joe asked our first email question about the necessity for a flyby or human orbital mission of Mars prior to humans landing on Mars.  We then discussed Mars, why a one way mission, and the Moon vs. Mars.  Other topics included spacecraft and rockets in general, Apollo, robotic missions, and more about human spaceflight.  At one point I asked Andrew how he stated the purpose for our going into space.  Bethany asked Andrew to explain what was meant by the term ecliptic. In response, Andrew offered a short explanation using basic orbital mechanics.  We talked about several specific videos on his YouTube channel including the Sagan Darkness video, the Ambien Space Music videos and the Star Trek and Darth Vader videos.  I asked him what he liked best and he said it was systems engineering because he liked putting and seeing how everything works together.  Human factors came up and he made an interesting statement to the effect that if we require 21st century medical care on our space missions, the technology itself may be an impediment to the mission.  We talked about the multi-systems failure risk being the biggest risk in his opinion and the steps taken to mitigate this risk.  I also asked about crew failure risks including medical and psychological issues.  Andrew offered us interesting observations about crew risks and issues so don’t miss what he said.  As the show was drawing to a close, we talked about his introduction to spacecraft videos.

We welcomed Dr. Bruce Cordell to the show for updates with his trend & Maslow Windows analysis suggesting a strong possibility for a boom ahead with a large space project.  During the first segment of our 1 hour 47 minute program, Dr. Cordell summarized his Maslow Windows theory over the economic history of the US showing how specific economic cycles lead to large, cutting edge projects approximately twice in a century.  He cited several examples but talked about the Panama Canal and our earlier space program culminating with Apollo and our lunar missions.  He said these projects are typically large exploration type projects, macro economic, and coming when there is a boom and the public is ebullient.  He said there are three precursors to the big project.  The three are economic, geopolitical, and space related.  Regarding the space precursor, he talked about the recent Chinese lunar rover mission and Chinese lunar orbiter and return mission.  He also said movies start tracking this too and he mentioned Gravity and Interstellar.  I suggested that many do not want a large government space project, instead opting for private projects and missions within LEO and even to Mars.  Dr. Cordell said it did not have to be a public venture and that it could also be a public/private partnership.  As a result of other questions, he said the next big space project might very well be a return to the Moon.  John from Ft. Worth called to talk about leadership issues, risk, and the lack of the 60’s spirit.  Bruce talked about the impact of the Sputnik moment.  John and Bruce continued their interesting conversation for the balance of the segment.

In the second segment, Bruce answered John’s question from before the break as to what may happen if China is the leader and commands the ebullience, not the U.S.  We also addressed BJohn’s question regarding China using older technology based on the Soviet space program while the US is cutting edge and would that not make a difference.  Don’t miss what Bruce had to say.  In the remaining minutes of the program, Bruce talked about his human spaceflight graduate class he teaches at USC in their Dept. of Astronautical Engineering.  The class will be taught again in the fall of 2015 and is available to qualified students as an online option.  As we were ending the show, I asked Dr. Cordell about timelines which he has connected to our 2016 presidential election.  He also said a major Apollo type project would need leadership from the US president.  I asked about a private sector leader and he had much to say about this possibility.  He mentioned that the economy over the next two years would be critical as we are not yet in a boom period.  He was unable to identify the political leader that would make this happen and said often during our discussion that JFK was not elected as a result of his space policy meaning that an interest in doing something great in space  might develop with a president after he/she is in office.

Welcome to this 2.5 hour Space Show Classroom discussion with Dan Adamo, Dr. John Jurist, & Dr. Jim Logan regarding the recently released NRC “Pathways To Exploration: Rationales And Approaches For A U.S. Program Of Human Space Exploration.”  You can download the report for free at  http://www.nap.edu/catalog.php?record_id=18801.  In addition, the project referred to in the last part of this discussion by Dan and Jim, the “Aquarius interplanetary HSF transport” paper can be freely downloaded at  http://www.spaceenterpriseinstitute.org/2014/07/aquarius-a-reusable-water-based-interplanetary-human-spaceflight-transport.  Please note that our panel members used cell phones which caused audio issues which you may hear during the discussion.  Finally, as this program will also be archived on both The Space Show and The Space Show Classroom blogs, there will be two papers uploaded to each blog, one by Dan Adamo & the other by caller Dr. James Dewar. I will mention both in the summary below.  In the first segment, our panel members opened with their perspective on the NRC Pathways HSF study.  While there were similarities in their perspectives, there were also noteworthy differences.  After this comprehensive introduction, I asked our panel members about the study and space settlement or pioneering.  Each panel member had much to say on the settlement issue, including the need to solve the gravity prescription for long duration HSF or settlement.  Our panel members  said that for the most part, space settlement was out of scope for this report.  In this part of the discussion much was said about microgravity issues & the need to do on orbit experiments to determine the HSF gravity prescription.  Deimos was discussed as an initial better choice that the surface of Mars re microgravity issues.  Our guests spoke to the need of a short arm centrifuge on the ISS.  Jim spoke to the specifics of such an experiment such as 1 G at the head., 2.5 g’s at the feet for two hours a day to see how it serves as a microgravity countermeasure.  Our panel members mentioned that there already was such a short arm centrifuge built years ago by NASA and Wiley, http://www.nasa.gov/centers/johnson/slsd/about/divisions/hacd/laboratories/short-arm_centrifuge_laboratory.html.  The guests talked about unknown human factor challenges for going to Mars and long duration spaceflight.  Jim provided us with interesting statistics on human spaceflight totals since the beginning in 1961.  The panel members had much to say about the budget issues discussed in the NRC study.  Another point brought up was the study’s assumption that if we are not going to the surface of Mars, why even do HSF?  Near the end of the first segment, listener Carl brought up the well known plans for Mars settlement with Elon Musk & SpaceX.  This sparked quite the discussion so don’t miss it.

In the second segment, our panel talked about the value of the Pathways study, international partnerships and what they saw as contradictory statements, especially regarding the mission cost impact of such partnerships.  John mentioned the study’s reference to NASA education & public outreach which he thought was more focused on STEM & the development of more engineers rather than on educating the general public to be more knowledgeable about science.  The panel members  noted that there was little attention paid to the societal impact of not even having a human spaceflight program.  Dan & Jim agreed on the importance of educational outreach and shared their experiences with us from the employment with NASA.  Adrian in San Diego sent in an email suggesting the panel was being pessimistic and that China would not overthink issues and just do missions without full disclosure.  All three panel members had much to say in response to Adrian’s charge of being pessimistic.  They talked about being reality based, not pessimistic & why it was so important to be reality based.  The panel hit back hard on the charge of being pessimistic.  Dan & Jim said to be other than realistic was reckless and irresponsible.  Jim also said that being called pessimistic suggested to him that reality had violated the person’s ideology.  Jim would be happy to debate the issues with anyone in open forum.  This discussion brought Jim and Dan to talking about their Aquarius project which you can download at the above URL.  They spent some time discussing the benefits of their approach, noting how it addresses & mitigates many of the problems associated with a HSF mission to Mars.  They also spoke to the need for nuclear propulsion and talked about using water as fuel and very high ISP ratings with high temperatures.  During this discussion, Dr. Jim Dewar called in to suggest their ISP ratings were low, he explained why, and he talked about starting small to start flying and then improving as you go.  We did not know it but we lost John from the connection but Jim, Dan, and Dr. Dewar spoke to the NERVA project, and specifics about nuclear propulsion.  This advanced nuclear propulsion discussion was close to a half an hour near the end of the program.  Dr. Dewar was a guest on the program in 2008 & 2009 regarding nuclear propulsion & its history. He also authored two books on the subject.  Use the GuestSearch tool on our website to find his interviews which I suggest you listen to if you have not already done so.  I will also upload to both blogs the paper Dr. Dewar referenced in his discussion.  After the nuclear discussion, Adrian sent in another email titled “rebuttal.”  He challenged the panel members to do the experiments, not just to talk about them.  Jim, Dan & I challenged Adrian for his solutions to doing many of the needed & essential experiments. All of the panel members supported doing the needed experiments & have said so for decades.  Getting funding for the experiments, NASA approval, etc. is a challenge.  I then challenged Adrian to come to The Space Show as a guest with his solutions for doing the essential work & experiments rather than his just talking about how badly they are needed per his second email.  I hope Adrian does have answers and will contact me about coming on the show to discuss them with us.  Jim & Dan each provided closing comments focusing back on the study report.  They thought the report was worth it from the taxpayer perspective and that it would be used for references.  Jim did think the report was not as good as other government studies he had seen because it was so speculative, something all three guests addressed in their opening remarks.  An 11th hour call came from SLS John to talk about the ISP formula & temperatures Dan and Jim used in their paper Aquarius paper.  Dan authorized me to upload to the blog his written comments on the NRC Pathways study so you will find that document on both blogs as well.

We welcomed Michael Annis to the program to discuss his series of space & rocket history podcasts at http://spacerockethistory.com.  During the first segment, Mike told us about his background, being inspired by Apollo, and being a strong space enthusiasts going forward.  He strives for one podcast weekly.  Visit http://spacerockethistory.com/?page_id=344 for his timeline for existing podcasts with the newest on top.  Note that he started his series with his first podcast covering “Ancient Rocketry:  Standing on the Shoulders of Giants.”  As you will hear, he is still covering the Gemini program as his podcasts represent a detailed oral history in chronological order of events & missions that happened.  He does cover Soviet events plus events & rockets from other nations as applicable.  His sources are referenced in the podcasts but he does have a Source page, http://spacerockethistory.com/?page_id=27.  For this segment, we started at the beginning, talked about the history of rocketry and our space program.  One thing that I liked was his mention of the Flying Steam Powered Pigeon by Archtytas about 428 BC (see http://kotsanas.com/gb/exh.php?exhibit=2001001).  Listeners asked Mike questions about NewSpace, the Saturn V rocket, and for his favorite missions.  In this segment, Mike talked about the space interest of his students & their knowledge level of space history which was not good.

In the second segment, Mike mentioned Newton’s laws, especially his Third Law of Motion, especially action-reaction as he said rockets were based on this.  Our guest was asked about Mars as the focus and goal of human spaceflight and if he thought the US would likely lead a humans to Mars mission.  Another listener asked him about failures and he mentioned what he called a Flopnic, the Vanguard TV3 launch and the Soviet R7 rocket.  When asked about challenges to our space program, he cited budget problems.  We talked about the U.S. private sector which he supports.  Mike told us how to get his podcasts as they are available on iTunes and Stitcher.  Near the end of our program, Mike was asked about the Moon-Mars debate and his thoughts on the overall condition of our human spaceflight program.
