John Batchelor and I welcomed back Marcia Smith of spacepolicyonline.com to discuss the NASA 2016 budget per the recent decisions made by the House Appropriations Committee. We discussed SLS, Planetary Science, Orion, Commercial Crew, cuts to Earth Sciences plus the criticism against these allocations by both The White House and NASA Administrator Charles Bolden. We also talked about Mr. Bolden’s comments saying that if commercial crew were not fully funded, it would seriously delay the program. While the committee allocated a larger amount to the commercial crew program than before, it did fall short of what both The White House and NASA said the program needed. We also talked spending caps and sequestration. Marcia explained how that would work as overall the total spending for the agencies involved have to stay within the caps but the allocations within the agencies can differ which is why there are winners and losers. John questioned Marcia on SLS as he was not that supportive of it. Note what Marcia had to say about SLS but whatever one thinks about it, the program clearly has the support of many in Congress.

We welcomed Paul Turner to the show to discuss his new book “The Space Trade” and his concept for developing orbital real estate for profit. Visit his website for more information, http://www.thespacetrade.com.  In the first segment of our 1 hour 55 minute show, Paul introduced us to The Space Trade idea.  He first described what the mature space trade industry would look like, then he talked about how to develop a space trade.  He suggested the space trade would likely start with asteroid mining and he referenced Planetary Resources multiple times during our discussion.  He also mentioned the need for an orbital transfer vehicle and a spin ship which he described later in the discussion.  He talked about mining water and bring it back to LEO.  He recalled he had seen a suggested price for water at $50 million/ton in LEO which he said was on the Planetary Resources website at one time.  Later in the segment, this price was disputed by several listeners.  Listeners asked questions about the potential profitability of the space trade early stage since Paul thought it might not be profitable at the start.  Another early industry suggested by Paul was the servicing and refueling of satellites.  Joe then asked if a proof of concept could be applied to capturing small asteroids near Earth and bringing them back to Earth targeting their re-entry to land in Australia somewhere.  Paul said it was possible and it was important to have a proof of concept for people to see. John from Ft. Worth called to inquire about space manufacturing.  Paul had much to say about this part of his concept.

In the second segment, a listener asked about property rights and the national as well as international legal regime to make possible the space trade.  JP emailed in about manned vs. unmanned asteroid mining.  Benny asked Paul to describe a spin ship.  Later Robert inquired if lunar development might be the starting point for the space trade industry rather than asteroid mining. Listeners asked Paul many other questions including one about why establishing a space trade was important.  Paul referred us to chapter 12.1 of his book but he did mention a few of the reasons.  Later, he talked about the Carrington Event. I asked him what our TRL was for getting the space trade going and he said we could start today.  Don’t miss what he had to say about this.  In closing comments, he advocated doing something rather than just talking about it.  Pooley then called to talk about DIY space plus they discussed the old Conestoga project and JP emailed in on that as well.

Please post your comments/questions on TSS blog.  You can reach Paul Turner through me.

We welcomed Dr. Frank Martin to the program to discus the NRC human spaceflight study along with all aspects of human spaceflight including various destinations and missions.  During the first segment of our 1 hour 39 minute show, Dr. Martin introduced us to the NRC Pathways study which you can download for free by using Google.  He suggested it was a dose of reality as well as optimism.  He said the study was very clear in saying “show me the money” for those wanting to do humans to Mars missions now or fairly soon and then explained some of the high costs and trades involved in these missions.  One of his overriding themes throughout our discussion was the need to manage a very large mass in LEO in order to accomplish the goals of long duration human space mission.  During our segment, we kept coming back to the need to manage a large mass in LEO and how this translated to costs as well as the need for technology advancement.  Both myself and listeners asked our guest about doing human missions cheaper by using the private sector.  This subject kept coming up during both segments of the program.  We also addressed the rational for human spaceflight.  In addition, the issue of walking away from HSF was looked at for the US as a nation as that is an option. The report attempted to address this and related issues.   Joe sent in an email about the mice on the ISS and using them to determine the gravity RX for HSF.  He sent us several additional emails on this subject as well.  This prompted comments about the need to use the ISS for research in support of long duration HSF missions.  Dr. Martin said Mars was an horizon goal.  In this context, he talked about only a few other possible destinations near us, either the Moon or an asteroid.  He then proceeded to address the issue of managing the risk for a Mars mission.  Beverly asked a budget question and taking the lead from the most recent Mike Griffin interview, she asked Frank if it really was just a choice to be constrained by budget issues.  While Frank agreed it was a choice, he said there were very good ways and choices to spend taxpayer money so he did not see significantly more money for space in the future.  Another listener talked about nuclear propulsion which also crossed into the second segment.  Near the end of the first segment, we got a call from a New Zealand listener.  During his call, the idea of the Buzz Aldrin Mars cycler came up and there was a question or two about fuel depots.

In the second segment, I asked Dr. Martin why the study took 18 months, then SLS John called the program.  John wanted to talk nuclear propulsion thinking it would be a cost saver but what was not known was the accurate cost of the R&D program or the cost for jumping through political hurdles.  John suggested a new administration would make a difference and I challenged that.  I asked Frank given all his years of space industry experience if it was reasonable to expect big changes in space policy due to a change in administrations.  Don’t miss Frank’s reply.  Dwayne called back to question the HSF rational. One of the points made by Dwayne was that cooperation with the Russians on the ISS does not modify Russia’s behavior other than for space.

We welcomed Professor Henry Lambright of Syracuse University to the show to discuss his excellent book “Why Mars: NASA and the Politics of Space Exploration.”  During the first segment of this 1 hour 33 minute program, Dr. Lambright introduced us to his book and what prompted him to write it.  Dr. Lambright then described three main motivating factors for having our Mars program starting with before NASA with the belief and cultural components suggesting some sort of life on Mars.  Next as a motivating factor dating back from the Von Braun time frame of humans going to Mars.  His third motivating factor had to do with political issues and competition.  Since we were talking about the possibilities of life on Mars, I asked our guest about Viking and the more recent pronouncements by Dr. Gil Levin who has been on TSS several times over the past few years.  Later, Dr. Lambright had many good things to say about our science and robotic program but said our human spaceflight program was in disarray.  Dr. Lambright got several listener emails & phone calls.  He was asked for the WHY behind human spaceflight and that led to a discussion about Big Science. I asked him to define Big Science which he did.  We talked about the NRC Pathways HSF study, then our guest talked about triggers leading to big events and progress, plus the more typical method of moving forward which he called slow evolution.

Jumping forward to our second segment, we talked about the Clinton years in the 90s for policy, Mars Observer & how that loss was turned into a plus for our Mars policy.  Other topics included astronaut risk taking, the void in leadership for space, Mars, and things in general.  Doug called to consolidate all the motivating factors and issues to just one, the need for more money.  He made a good case for this consolidation.  We also talked about the challenges for getting alternative theories seriously considered by NASA, Congress, and policy makers.  The NASA to NACA suggestion came up, we talked about the privates taking over LEO with NASA focusing on BLEO & advanced technologies.  As the program was ending, I asked our guest about the Syracuse student interest in space and Mars, plus our guest left us with an important closing comment.

Please post your comments/questions on TSS blog. If you want to reach Dr. Lambright, you can do so through me.  Finally, if you buy his book from Amazon, do so through the OGLF Amazon portal so that Amazon will contribute to The Space Show.  Instructions are in each archive write up and on the blog, plus both The Space Show and OGLF websites.

We welcomed Brett Stroozas to the program to discuss the new space burial company, Elysium (http://elysiumspace.com).  During the first segment of our 1 hour 29 minute program, Brett introduced us to the concept of space burial and in particular the new start-up, Elysium Space Burial.  He went over their services and their marketing to both customers in the U.S. as well as Japan where cremation is the common thing.  He gave us some interesting funeral industry statistics for both the U.S. and Japan and we learned that they have a Japanese language website, http://jp.elysiumspace.com.  We talked about their launch services which he said would likely be with SpaceX or Orbital but in any event they only plan to use a U.S. launcher. Also, they do not at this time have plans for suborbital launches, only orbital launches and from the established launch sites.  We talked about their expansion plans to BLEO services and learned of their mobile app which you can get from their website for Apple and Droid products.  The company has seven employees, some of which are part time.

In the second segment, I asked Brett how his company differed from the competition.  He talked about the personalized services they provide plus their intended use of dedicated spacecraft.  He also talked about the media and PR received by the firm in their first year of operations.  Listeners asked for his process when working with a completed kit, and if their memorial services were non-denominational which they are.  Blair emailed asking about their plans to use smaller launchers such as Microlaunchers. Brett said not yet but possibly down the road.  Alex asked about using government launches over private mission launches.  Others wanted to know more about their future plans and what countries they had their eyes as future markets.  India was mentioned as one such company.  When asked for their 5-7 year plan, Brett spoke about driving the costs down and launching 5-7 memorial flights per year.  Near the end, a listener asked about green funerals and Pooley emails us asking about their plans for a fast decaying LEO.  Also in this segment and in the conclusion, Brett offered a special deal for Space Show listeners so don’t miss it.

Please put comments/questions on The Space Show blog above.  You can contact Brett Stroozas through his company website, his personal website (www.stroozas.com) or me.

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.

We welcomed Dr. Jim Logan and Dr. John Jurist to this special 2.5 hour Space Show classroom in-depth discussion on space radiation. We focused our discussion on deep space, Mars, the Moon and BLEO missions. Note that on both The Space Show blog (see above) and The Space Show Classroom blog (http://spaceshowclassroom.wordpress.com),  Dr. Jurist has a Power Point presentation on radiation.  During the program, our guests referred to specific slides that you will want to check out.  In our first segment, Dr. Logan started out by telling us about his interest in the subject, why he has been writing a paper on the subject for publication, and how this Classroom show came about.  He cited our short duration spaceflight experience, the Apollo missions, Space Shuttle flights, and then how things started to change when we had six month ISS visits.  Dr. Logan also made it clear that space was not a benign emptiness type of environment.  He said the reality was that interplanetary space was a sea of disruptive ionizing radiation wrecking havoc on biologic systems.  We moved forward in our discussion from that point.  We talked about the findings of the MSL RAD instrument regarding radiation on the way to Mars and on the surface of Mars.  Both John and Jim spent some time putting the RAD numbers through analysis to let us know what this means for human missions to Mars.  We talked shielding, possible materials, passive and active.  We talked extensively about water and the use of hydrogen as well for shielding.  Our guests addressed the two types of radiation, the GCR (galactic cosmic rays) and the CME/solar flare.  Here, John suggested listeners look at his slide 13 as we talked about protons and neutrons.  Jim said there was no magic bullet and talked about shielding effects of Earth’s atmosphere.  Pay attention here as Jim introduced us to the  RP scale.  For being on the surface, he said nothing less than RP100 would suffice.  For the vehicle, an RP5 was required.  John introduced us to career limits for radiation for men and women astronauts of different age but the career limits are for LEO and not BLEO.  BLEO limits are expected to be more restrictive when made public in April 2014.  Earth Mars transit times were discussed, especially in the context of Brian’s email that suggested a 180 day transit time.  Both our guests said that was unlikely with chemical propulsion and all of us again stressed the need for nuclear thermal propulsion.  Microgravity was talked about, especially in the context of side effects due to the radiation environment.  Jim then brought up the EVA subject and spacesuits.  Briefly, Jim said that quite possibly the ISS construction represented the zenith of EVAs which may become a thing of the past.  Don’t miss why he said this plus his description of serious spacesuit limitations.  We talked about life support to Mars and here Jim suggested we should use Open Loop! Again, listen to the rational behind this recommendation.  Don’t miss what our guests said about theories & movies making it sound easy to go to Mars and that the radiation would be nothing more than just a few more cigarette packs a year.  Our last topic addressed informed consent issues.

In the second segment, I asked our guests for a readiness timetable were there sufficient funding and technology advancements.  I also inquired if Russia, China, and others assessed the radiation risks in a similar way to the U.S.  We then talked about radiation and space pregnancy, fetus development, birth, and informed consent for the fetus, a baby, and a child under 18.  Ethical issues regarding child birth and space pregnancy were talked about as well.  Curt had sent in email questions which our guests answered, especially about drinking irradiated water and microgravity DNA damage & what this may mean for radiation effects.  Next, I asked Jim and John to tell us their 2-5 steps for the start of designing a Mars human mission.  Jim went first and listed Day 1 and Day 2 activities, John listed his top three priorities which were different than those suggested by Jim.  Don’t miss this discussion as its very instructive as to how to do or at least start mission planning for a human mission BLEO.  Roger sent in a question asking if the crew should be senior citizens since they have more resistance to radiation.  Don’t miss what our guests said about this idea.  It may surprise you.  Our next topic was would going to Deimos be easier.  Yes, it would but it would be a very different kind of human  mission.  Jim had some great comments about Mars gravity.  Briefly, he said it was the “best.” Later, when asked to compare the Moon and Mars, our guests said lunar radiation was worse than Mars.  Also, the Mars atmosphere does provide limited shielding while there is no such thing on the Moon.  Jim had earlier talked about a sphere being the perfect shape for an interplanetary spaceship.  Shelia emailed in wanting to know if heavy lift made a difference and if the sphere was so good, why were capsules being used? Don’t miss the response.  We then talked about the complexities of rendezvous and docking, especially in the context of fewer launches (heavy lift) as compared to many more launches (smaller rockets).  Near the end, I asked our guests if either thought our nation, the public, NASA, our leaders and politicians were sufficiently motivated to do a human Mars mission.  Jim did not think so and had much more to say in reply to this question.  John was more pessimistic.  Both thought it was more likely that the private sector would mount a human Mars mission rather than our seeing a government mission, but raising the needed capital might turn out to be a show stopper.  The three of us then talked about what it was like growing up in the 40’s, 50’s, and 60’s as compared to today.  John and I (John is a bit more than 2 years older than me) were probably more harsh than Jim in our assessment of today, but we all realize that the younger generations will be taking us to space, building the next smartphone and more. I talked about my visits to Google, Apple, SpaceX, etc. and the excitement in the air in belonging in their work forces which does not seem to exist with NASA. This opened the door for Jim to put it on the line about his NASA experiences and the potential opportunities providing NASA can somehow reorganize.  He did not think the type of reorganization he was talking about would happen.  Both our guests left us with excellent takeaway points and concluding pearls of wisdom.

Please post your comments/questions on the blogs. You can reach either of our guests through me.

We welcomed back to the show Bruce Pittman for a 1 hour 23 minute far ranging discussion on commercial space and related topics.  We started our first segment with the Planetary Sustainability Initiative.  More about this is available on the Sustainable Silicon Valley website, www.sustainablesv.org/ssv2013/index.php.  Bruce shared with us stories from the recent conference, including the fact that California Governor Jerry Brown attended and was involved in the discussions.  From this program, we talked about new technologies that could benefit life support for deep space missions including Mars as well as space technologies that could be used here on Earth.  Another example cited was the Bloom Box by Bloom Energy (www.bloomenergy.com).  Bruce also mentioned the SpaceX Raptor engine designed to use methane for BLEO missions.  In talking about 2013 commercial space, Bruce cited the successful end to the COTS program and we talked about emerging business opportunities on the ISS.  He also mentioned a change toward commercial space investments in the attitude of VC types in Silicon Valley.  In addition, he mentioned the blossoming cubesat and nanosat industry.  The Moon came up, especially in light of the recent Chinese lunar robotic lander and Bruce talked about the developing lunar and commercial space private ventures underway in the U.S. now.  Next, our guest was asked about public/private partnerships and here we had quite the discussion, especially with regards to some saying more government oversight was needed for commercial ventures.  Dave called in to continue the public private partnership discussion in light of the NASA Advisory Council and consideration toward applying such partnerships to heavy lift vehicles.  Bruce brought up the potential game changing technology for launch vehicle reusability.

In our second segment, our guest talked about the excitement ahead for 2014 given the advances with the suborbital companies, the potential start of space tourism, and more.  We talked about the Google Solve For X program focusing on fusion energy.  Bruce mentioned advances with LENR. Doug called to talk about the Space Act Agreement and budgeting issues for space and the private companies.  We concluded our discussion with a preview glance at the 2014 ISDC Conference to be held in Los Angeles in May.  The last listener question dealt with Mars One and Inspiration Mars. Bruce offered a few comments on both program.

We welcomed back to the program Dr. Dennis Bushnell, the NASA Langley Research Center Chief Scientist.  Dr. Bushnell discussed his paper, “Advanced-to-Revolutionary Space Technology Options-The Responsibly Imaginable.” which can be downloaded at http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20130011698_2013011376.pdf.  In the first segment of our 1 hour 26 minute show, Dr. Bushnell summarized the findings in his paper and talked about how we are still building on technologies from the 50’s and 60’s that were based on “living better with chemistry” and ICBMs.  We began talking about advanced propulsion including nuclear, but our guest made it clear throughout our discussion that what was needed was a reduction in the cost of space access by a magnitude of 10, not by two which is what is happening with new commercial rockets coming on line.  In fact, later in the show when discussing commercial space, Dr. Bushnell was clear that to close a commercial space business plan the reduction in launch costs by a factor of ten was absolutely essential!  I asked our guest to tell us where the bottlenecks were and he said it was in the culture & big cultural changes were required to move forward.  He also talked about the need to experiment and try lots of options and ideas, to triage them, down select, fly them, and choose the best based on the engineering process he described.  We talked about the low technology readiness level (TRL) of many of today’s space ideas and technologies, that we have become focused on instant or near instant gratification but that the process he was talking about would extend over a 25 year period.  Given this, his paper is a frank and factual discussion of many of our space industry segments, a no nonsense, no Kool Aid TRL analysis of much of what we talk about and say we can now do in space or will be doing in the near term.  Safety was discussed, including microgravity, radiation, plus a mention of unknowns regarding what we already know about gut bacteria exposed to radiation given our limited amount of research on this topic to date. A listener asked him about physics as a main reason for space exploration and contrasted that to settlement as the main reason for HSF. Another listener asked him about his mentioning USAF comments that indicated space was a mature and declining industry.  We began talking about commercial space, but we talked about it through the second segment as well.  In this segment, Dennis talked about how we have created economic growth in the past but now we have not only the challenge of economic growth but sustainable jobs and sustaining our standard of living.  Terraforming Mars was discussed as part of our discussion about Inspiration Mars and Mars One HSF missions to Mars.  As this segment ended, a listener asked him about suborbital space and citizen science projects.

In the second segment, John Hunt called in to talk about the high cost of many advanced space technologies, plus he wanted updates on LENR (this used to be called cold fusion).  Dr. Bushnell had much to say about LENR and it potential, we talked about Rossi, and the NASA work being done to better understand LENR effects. With an understanding of it, funding would not be as big a problem as it is today.  He also said LENR had the potential to be transmutational.  Our guest suggested that for more information, we visit the Larsen LENR slideshow:  www.slideshare.net/lewisglarsen/slideshows.  Again, he pointed to cultural issues as major stumbling blocks to this research.  In returning to the focus of his paper, he said there was no shortage of ideas but the culture was preventing them from being tried, tested, and exploited.  Rocket reusability was brought up, our guest mentioned the SpaceX Grasshopper work, and he was asked about SLS and fuel depots.  I asked about BLEO issues and radiation.  In response to another question, he said that were he the space guru, he would focus on “energy” and structural materials. You will want to hear this discussion. Later, Tim called from Huntsville about radiation and HSF to Mars, as well as the economics of the Big Dumb Booster.  I asked Dennis about the target audience for his paper and he said it was meant for NASA and the world since space fairing is a world endeavor. He again talked about potential revolutionary technologies which are needed and which would benefit all of us.  He repeated that we must do the difficult and take the risk and invest.  We also need to look forward with multiyear planning.  Near the end of the program, Dennis was asked about space elevators which he was not enthusiastic about.  Again, he repeated that we needed to make investments to raise our TRL levels.  At the end, I asked why space does not rise to importance in presidential campaigns & elections.  He said space was very good as an Earth utility but beyond that, there was no clear basis for most of it and that was the problem. Don’t miss his comments on this topic.  Our final topic was his assessment of commercial space given his years spent working on it with NASA including budgets into the hundreds of millions to find a way to close a commercial space business case for commercializing the ISS and other things.  This is a very important short discussion, don’t miss it.
