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. Hannah said the new breed of space entrepreneurs and advocates are not promoting space settlement and issues the way it was promoted in years past which is what Linda was describing. We talked about the diversity among the NewSpace attendees which is vastly improved from the past, especially with women and Asians. In this context, we discussed technology, space settlement, Manifest Destiny, and much more. Hannah indicated that this new group of advocates was looking to establish more collaborative space eco-systems. Listeners emailed Hannah about diversity issues and finding ways to involve more minorities in space advocacy. Space attorney Michael Listner called to talk about advocacy and related issues from his perspective which was different than what Hannah was describing. Don’t miss this discussion. Hannah left us with closing comments you will certainly want to hear.

We welcomed Damian Peach, well known amateur astronomer from the UK to the show.  Visit his website for more information and to see his work, www.damianpeach.com.  During the first segment of our 90 minute program, Damian talked about his early interest in space and the definition for an amateur astronomer. We learned most are self taught as was the case with Damian, that the field was not as math intensive as a professional astronomy career and that amateur astronomers significantly contribute to the field of astronomy and work well in harmony with professional astronomers.  During this segment, listeners had many questions for our guest including asking if he had sponsors, the cost of amateur equipment, his typical viewing schedule on the South Coast of the UK where he lives and his other location, Barbados.  In fact several questions came in about viewing conditions in Barbados and the effect of weather and humidity on his viewing in that location.  Damian likes to photograph Jupiter and Saturn and the bigger outer planets.  Don’t miss the why behind this.  As you will hear and you can see on his website, he has also done lots of excellent imaging of the Moon.  I asked him about his interest in going to Mars, human spaceflight, and more, all of which he said he was interested in.  Other first segment topics included wanting to know more about his techniques, amateur spectroscopy, and amateur peer review.  Regarding his interest in Jupiter, he talked at length about the always changing Jupiter weather that he liked to document in his Jupiter photography.

 

In the second segment, he talked about the upcoming JUNO Mission to Jupiter & the need for amateur astronomers to take images and submit them to the JUNO team.  Other topics in this session included cubesats, amateur astronomy groups in Europe, the U.S. and elsewhere, plus Pluto and New Horizons.  Listeners asked about amateur solar and deep space astronomy, cosmic rays, and more.  Science fiction came up as did the movie Interstellar.  Later, Ben sent in a note while looking at Damian’s Mars images on his website and asked about color enhancing and photo touchups.  Imaging Mercury and Venus came up in the discussion as did light pollution, viewing & searching for comets & NEOs.  Near the end of the program, we talked about Ceres and the Dawn Mission from the amateur perspective.  Near the end, I asked Damian his first choice mission were he the space mission guru.  I bet you will be surprised by what he said.  Dr. Dewar asked about making space access available with space based telescopes through nuclear propulsion given the cost of launch would be so much cheaper. Don’t miss Damian’s response.  Marshall called at the end to talk about technology advancement & more.

We welcomed Dr. Bruce Damer back to the show to discuss his new concept for enclosing an asteroid with a Xenon gas filled enclosure, the Shepherd concept, to help make human spaceflight sustainable. During the first segment of our 83 minute program, Dr. Damer introduced us to the concept, compared it to the NASA ARM baggie option as well as the boulder option, plus the private sector potential for the mission even without NASA. You can read the paper we talked about during the show which was recently published in New Space, “Shepherd: A Concept for Gentle Asteroid Retrieval with a Gas-Filled Enclosure” at http://online.liebertpub.com/doi/full/10.1089/space.2014.0024. During this segment, Dr. Damer talked about capturing fuel in space and talked about a demo project, possibly in LEO. Doug emailed in several questions and comments about the NASA ARM video, then asking if Dr. Damer’s idea could be used to extract the most valuable volatile thus only having to bring back a portion of the asteroid. Don’t miss what Bruce had to say in response to Doug’s comments and questions. Claire in Boston emailed in to voice her unhappiness with ARM and the fact that many others like her did not like the mission. She asked Bruce what the value was even with his idea rather than using the resources for returning to the Moon or going to Mars. Bruce suggested the mission would produce excellent science and enhance commercial spaceflight. Again, don’t miss his full answer to Claire’s question. One of the later topics in this segment dealt with forces on the asteroid in the baggie concept that could possibly destroy the asteroid. He explained why Shepherd would probably be different.

In the second segment, Dr. Damer talked about the Shepherd mining variant, the Shepherd biological variant, and the Shepherd fuel variant. I asked him if this was similar to 3D printing in space and he said it was, then he explained his answer. He also said the founders of the Shepherd idea were putting it out to everyone as Open Source as he said would be valuable to give it away to industry. Later he said the most likely to develop this technology would be NewSpace entrepreneurs. Jim in Denver emailed in about the applicability of Shepherd to human spaceflight to Mars. Here, Bruce talked about orbiting Shepherd models supplying the surface group below. He also said being on the surface may not be the best way to set up a settlement but listen to the total scope of his comments on this subject. He even cited Von Braun, Bonestell, Willy Ley and others for depicting this idea using a Mars transfer orbit. Tim called in with several questions about short period asteroid. When asked for concluding comments, Bruce said he was very excited about Shepherd as it represented 35 years of simulation and other work and now he was meeting with the right people with the right skills to make a project like this happen.

We welcomed Dr. Richard Binzel to the show to discuss asteroids, the NASA ARM, and completing the NEO survey.  During the program, Dr. Binzel referenced two items. The first, his article in Nature is at http://www.nature.com/news/human-spaceflight-find-asteroids-to-get-to-mars-1.16216.  The National Academies study he mentioned is at http://www.nap.edu/openbook.php?record_id=12842.  During the first segment of our 90 minute program, Dr. Binzel introduced us to the asteroid topic, the asteroid belt, 1 km size asteroids and he responded to my questions about Asteroid UR 116.  Our guest then addressed the NASA ARM and explained why he is not supportive of it.  He referenced his above article in Nature on the subject.  You can get this article at the above URL.  He talked about visiting asteroids in their natural orbit rather than bringing a small one back to orbit the Moon.  He had much to say that was positive about visiting an asteroid, explaining as well why such a visit is on the path to HSF to Mars.  He then explained his program for completing the NEO survey which is to find and catalog specific NEOs.  Listeners asked him many questions including if radar was a good tool for finding asteroids.  He said no because it uses a very narrow beam.  He also said that were the NEO survey completed, most of the most accessible destinations for HSF and science missions would be cataloged and would open up space.  He goes into detail on this near the end of our show.  We talked about international NEO survey and planetary defense issues.  While the U.S. remains the leader, ESA is doing more and more.  He also said that rather than spending just $20 million on asteroid detection, we should be spending $200 million annually until the survey is completed.  Joe in Houston sent in a series of questions starting in this segment and ending when the show ended.  His questions, all of which were read on air, centered around ways to bring an asteroid into orbit around the Moon.  Listen to what our guest had to say about his multiple suggestions/questions.  Professor Binzel clearly likes and welcomes fresh ideas & also insists on running the numbers and doing the trade analysis.  John called from Ft. Worth asking about the size of an asteroid that should be getting our attention.  Time lines were brought up as we need time for the best way to deflect an asteroid on an Earth collision trajectory.  Near the end of the segment, our guest talked about a NASA Grand Challenge Mission around asteroid detection and intervention methods starting first with the survey, the concepts on how best to deflect an asteroid and then about 30 years out, a contest on an ISRU test for resource extraction on an asteroid.

 

In the second segment, Doug sent in multiple questions, then after I asked our guest a few of them, he called in to talk about some of the other questions on his list.  Doug asked Dr. Binzel good questions so listen carefully to their discussion.  One thing of note was that the size of an asteroid presenting the greatest risk to Earth is 140 meters.  Joe continued emailing evolutions of his initial three questions from the first segment.  Asteroid ISRU was again discussed in this segment, so was the likelihood of a comet impact on Earth, & a privately funded mission to complete the NEO survey was also discussed. As the program was ending, Dr. Binzel spoke to the issue of the NEO survey being a game changer and opening the gateway to our future.  This is important so do listen to his comments on this issue.

 

Please post your comments/questions on The Space Show blog above.  You can reach Dr. Binzel through me or his MIT faculty page.

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.

We welcomed Bruce Pittman back to the show to discuss the emerging commercial space industry. During the first segment of our 90 minute program Bruce said this was the most exciting time every for commercial space, certain in his 30 plus year career.  He talked about there being a paradigm shift underway, NASA challenges and the progress made in just five short years.  He cited examples with COTS, commercial payloads to the ISS, SpaceX, and lots of smaller companies working with small satellites.  Other examples included the 3D printer on the ISS, the growth of spaceports, the industry spreading out into multiple states, and investment capital coming to the industry.  I asked about human spaceflight (HSF) and he said it was more challenging and demanding but was optimistic that launch costs would come down, especially if reusability enters the market.  Reusability would greatly assist in bringing more commercial options to the table even for HSF.  Jerome in the UK emailed to ask about a commercial space industry outside the U.S.  Both Bruce and I commented on Jerome’s question.  Harry emailed Bruce to inquire if going public was essential for pushing the emerging commercial space industry forward.  Bruce was also asked what excited him the most in the industry.  Listen to his choices. I asked our guest if he saw SLS as an asset to the emerging commercial space industry, being neutral, or being a detriment.  He believes there will be synergistic enhancements for both SLS and the commercial space industry through the development of SLS.  Don’t miss his full comments. Bruce was asked about commercial space ventures being able to finally close a business case and having more than just government as the customer.  Allison emailed us asking Bruce to define paradigm shift.  This also proved an interesting discussion.  Near the end of the segment, our guest was asked bout NEOs and commercial opportunities.  We also talked about two NASA papers in this segment.  The first, “Pioneering Space: NASA’s Next Steps on the Path to Mars” from May 29, 2014 can be downloaded at http://www.nasa.gov/sites/default/files/files/Pioneering-space-final-052914b.pdf.  The second paper, “Emerging Space:  The Evolving Landscape of 21st Century American Spaceflight,” can be downloaded at http://www.nasa.gov/sites/default/files/files/Emerging_Space_Report.pdf.  Just before the break, Paul asked about fuel depots for the commercial space industry.

In our second segment, we started talking about space settlement, pioneering, and space exploration.  Bruce explained the differences with pioneering making it possible to have a permanent presence in space by getting in place needed infrastructure and the basics for living in space.  Space settlement would be established after pioneering.  Exploring goes forth to find out what is out there and to return to tell about it.  A listener asked if going to the Moon was a pioneering step on the way to Martian settlement.  Later, Bruce said that pioneering will be driven by economics. In this segment, we also talked about property rights and benefit sharing plus the impact these two issues might have on the emerging commercial space industry.  Risk averseness came up as well.  As we were drawing to a close, Bruce mentioned how all of the industry was in a transitional period, including traditional aerospace.  He suggested things to look for over the coming months included more commercial activities on the ISS, the upcoming Bigelow module for the ISS, & the Google Lunar XPrize.  In closing, we talked about Silicon Valley and the industry as well as the lowering of barriers to entry for emerging commercial space companies.  Bruce also mentioned the Next Giant Leap Conference in Hawaii, Nov. 9-13, 2014.  For more information, see http://2014giantleap.aerospacehawaii.info.

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 Dr. Martin Elvis to the program to discuss asteroid mining, commercial space, NASA & more.  In the fist segment of our 91 minute discussion, after telling us about an asteroid being named after himself, Martin responded to my question about what he sees as our future in space.  Dr. Elvis answered this question throughout both segments of today’s program, making it clear that he sees solutions and development through astronomy & commercial space, not NASA.  He began talking about our great space telescopes and the fact that the budgets are not there for such great tools and instruments to continue and be sustained, even to the tune of not being able to properly support the JWST.  He had much to say on rising costs, budgets and when I asked about priorities, he said how much is the right amount to make space exploration, science, even HSF, a priority?  What is their information worth compared to other worthy causes and uses for federal money?  This analysis has led him to understand the future rests with commercial space to pay for space programs and ventures rather than relying on government funds.  We then jumped into mining asteroids and the commercial potential of this emerging industry.  He talked about initial small markets, maybe 10 worthy asteroids for mining or possibly doubling that number given uncertainties and risks associated with the formula for estimating the number of commercially viable asteroids.  Do not miss this discussion as I am sure we will be referring to it frequently in future Space Show program discussions.  The size and type of asteroid matter as you will hear with mining needing at least a 100 meter wide asteroid in the billion dollar range with Delta V requirements that are cost effective for getting to and from the target.  Primarily we talked about water and PGM re asteroids.  Listeners asked questions about trillion dollar asteroids per press reports, he looked them up and said the Delta V to get there, land, etc., was simply too high, a fact often ignored by articles referencing potential asteroid value.  Doug emailed in about smaller asteroids, say 20 meters.  Dr. Elvis had much to say about the smaller asteroids and their mining potential as well.  Toward the end of the segment, we talked about regulatory and legal-illegal acts including the possibility of a competing company hijacking an asteroid for commercial purposes.  Don’t miss what he said about this.

In the second segment, we started with a call from Doug.  Doug and Martin had a log discussion as Doug wanted to compare mining potentials for asteroids and the Moon.  Later, we talked more about space telescopes and Doug wanted to know if Hubble could be pointed in the direction of the sun for specific reasons.  Later, we talked about Rosetta and P67.  B John in Sweden sent in lots of questions about why not mine the Moon rather than an asteroid.  Martin explained the value of going to an asteroid for mining and getting virgin scientific info over the Moon so listen to this discussion.  Other topics included economics, depressing prices of PGM here on Earth by bringing this material back to Earth, zero G issues, Pluto, Kuiper Belt Objects and more.

Welcome to this 2 hour 1 minute program.  In our first segment, we started with the first caller, Richard Easton who told us about the passing of his Dad, Roger Easton, the father of GPS.  Richard has been a guest on the show several times &we were most fortunate to have Roger as a guest as well several years ago.  We took this opportunity to honor Roger Easton & talk about the early days of Roger’s timing work which formed the backbone of GPS.  Richard went through some of the early history with us as he has done on previous shows. I urge you to listen to this call plus go back and listen to Richard’s earlier shows, including his first one when Roger was with him. You will hear oral history at its best & from the major scientist/engineer who brought us GPS.  After Richard’s call, we took our first break.

In the second segment, I read a NASA PR announcement about the successful recovery of Dragon bringing back 3,500 lbs. of cargo from the ISS.  Congratulations to SpaceX and NASA!.  John from Ft. Worth called to talk about the U.S. sanctions on Russia regarding the Crimea/Ukraine, the Atlas 5, the RD-180 engine and various straggles that might unfold for the ISS.  John was asking thought provoking questions which neither of us could answer but we do know the situation is largely political rhetoric and posturing right now but could easily change.  I asked John if he thought we might fast track the development of HSF and Dragon.  As he said, we wait and see.  Next, I took a very short break to return with my attempt to respond to the questions about Russia, the ISS, and sanctions asked by Kelly in his email which I read on air.  Our next caller was first time caller John from New Jersey who took us through to the end of the program.  John’s call was an excellent one & I urge you to listen to what he had to say.  We talked about the old shuttle policy, the possible use of depots, lunar settlement & using the Moon for training and experience to go further out in space.  We also talked about Mars and asteroid mission, then the issue of leadership came up regarding policy & in particular, space.  Like so many of us frustrated by our current situation, John was unable to find answers to how to advance policy.  I asked him if the militarization of space by another state actor might be a driver for the type of space activities we had been talking about.  He did not think so but listen to his answer.  One of his favorite comments  was to the effect that “we are having Star Trek dreams in a wagon train universe!”  Prior to ending our program, I went over our upcoming Space Show schedule.

We welcomed back Dr. Clay Moltz to the show to discuss his new book “Crowded Orbits: Conflict and Cooperation in Space.”  Please remember to buy this book through the OGLF/The Space Show Amazon portal so Amazon will contribute to The Space Show.  Our Amazon instructions are in every archive summary and on each Space Show blog entry.  During the first segment of our 90 minute discussion, Dr. Moltz told us why he wrote the book which was to address orbital crowding, possible conflict in space and to bring these issues and others to the attention of the general public as space impacts everyone everyday.  A major topic for our discussion was space debris.  Using this field as an example, Dr. Moltz  made a very strong case for rules of the road, space traffic control issues, and responsible behavior by both governments and the private sector.  We talked about entrepreneurs and private groups resisting a more regulated environment and he made the case for the need for cooperation to avoid conflicts.  Early in his book, he outlined three significant points of view regarding the debate over space policy, ranging from conflict & the military use of space was inevitable so prepare for it to avoiding problems by piecemeal global engagement to increasing the use of international space projects through international governance.  Dr. Moltz received many email questions challenging a regulated environment and the need for more controls on space businesses and operations.  We talked about the cubesat technology and growth of the industry, the lack of registration, & as the industry grows, possible crowding problems.  We also discussed the U.N. treaties that seem to cover what we were talking about so why the need for more agreements & regulations?

In our second segment, we continued our human spaceflight discussion from the end of the first segment, plus we looked at space in other countries.  We mostly focused on China, India, Iran, and North Korea among others.  We talked about large scale industries that may develop over time such as SSP.  GPS was an example, then a listener asked about cyberwarfare & the impact on space policy.  Toward the end of the program, I asked about space interest among students at the Naval Postgraduate School. Students are very interested space and the subjects discussed in Clay’s book and on today’s show.
