We welcomed back Dr. Doug Plata to the show to discuss his selected trades for his Cis-Lunar One Transportation Architecture.  You can find Doug’s Choices of Selected Trades document on The Space Show blog at http://thespaceshow.wordpress.com under the summary for this particular program and date.  In the first segment of our 2 hour 6 minute discussion, Dr. Plata started out giving us an overview of his project, mostly by reading to us the “Overview of the Cis-lunar One Architecture” which is part of his document on our blog.  In addition, Dr. Plata wants your feedback regarding his project, including constructive criticism.  You can email Dr. Plata at dougspace007@gmail.com.  After discussing the project overview with us, Doug started addressing the trades listed in his document.  We started with Trade 1 Launcher.  Doug went through all of his considerations for launchers, was clear that he was not ruling any particular rocket out of the question.  Make sure you note his “Table1: Choice of Launcher & Fuel.”  The led us to discussing payload issues for the mission.  Also note that Doug has named his lunar craft the Condor upper state LL as you will see that name show up throughout our discussion.  Doug then went to Trade #2 and discussed propellant choices.  Note his Table showing the specifics of his Choice of Fuels assuming 53 tons at LEO and a 15% dry mass.  He received several listener questions, including questions about where to on the Moon.  See Trade 8 Initial Landing Sites for his choices and reasoning.  We skipped to Trade 12 Power in Shadows.  He discussed power options in some detail and went through the four options listed in this trade.  Mary Beth sent in some questions asking Doug about his propulsion discussion and Marshall called in with a series of questions about ice and the regolith.  Doug then took us to Trade 17 Repairs.

In our second segment, Doug started with Trade 17 repairs, focusing on redundancy, spare parts, & surface equipment easy designs.  Later in the segment, Dr. Plata was asked about lunar dust and maintenance/problems for the equipment.  A listener emailed him about market possibilities, our guest fielded other listener email questions and then Doug addressed Trade 9 Landed Configurations including belly landings and tail landings. Trade 14 Surface Equipment was discussed, then John called in to talk about a needed detailed lunar surface survey.  I asked our guest for his detailed cost projections for his mission followed by his next step in promoting his architecture.  He talked about having called his Congressman, Representative Mark Takano.

Please post comments/questions/feedback on TSS blog per above.  You can also email Dr. Plata at his above email address, plus its on his trade document which is on TSS blog.

We welcomed Rick Tumlinson back to the show for this 1 hour 53 minute program to discuss Rick’s commercial space ventures, space advocacy, NASA, space development and exploration challenges & methods for moving the “revolution” forward.  In the first segment, Rick opened up with updates for Deep Space Industries (DSI), asteroid mining, NEO defense, and more.  We also talked about Rules of the Road and possible industry regulation that the FAA is now talking about.  Much time was spent on possible NEO impacts.  We also started discussing the “opposition” to commercial space and new space directions over traditional aerospace programs and directions.  Following our discussion regarding DSI, we turned to another of Rick’s entrepreneurial companies, Orbital Outfitters.  Rick talked about their new & advanced spacesuit design version IS3, their opening R&D offices in Midland, Texas, plus he mentioned upcoming news with which the company will soon take public.  I asked Rick about modern day advocacy hurdles as compared to when the Space Frontier Foundation was first started.  This provoked lots of interesting comments and discussion points that crossed over into the second segment of our program.  However, he did say it was harder now so don’t miss the discussion and talking points.

In the second segment, we talked about the overall Texas commercial space development strategy, possible new spaceports for Texas, and their understanding of how the space industry is changing and becoming profitable.  We also talked about his most recent Huffington Post Op-Ed which will appear within a few days which was a reply to a Slate.com article by NYU Journalism Professor Charles Seife titled “What Is NASA For.”  You can see the article at
www.slate.com/articles/health_and_science/mysteries_of_the_universe/2014/02/nasa_s_mission_its_search_for_meaning_has_limited_its_science_and_damaged.html.  While Rick pointed out the problems with the article, he also talked about the author’s perspective being valid.  Don’t miss this discussion.  We also talked about public/private partnerships with Doug & the need to be commercially profitable. Lots was said about HSF to Mars and Deimos, plus returning to the Moon.  Rick also talked science & robotic missions along with HSF missions.  As the program was ending, Rick talked Big Picture with us and being caught up in space advocacy battles & the path forward.  He talked about culture, space exploration & development benefits for all of humanity, benefit sharing, and more.  He repeated many times that we are at the cusp, a turning point, a paradigm change moment.

Please post your comments on TSS blog.  Rick provided his email address for contact during the show or you can reach him through me.

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.

Welcome to this 2 hour 2 minute Open Lines discussion.  Jeff was our first caller regarding propulsion, SLS, Orion, SRBs, ATK, advanced technology as compared to existing or old technology, composite materials, and much more.  I also asked him about sequestration in the defense side of space.  Todd sent an email to Jeff to inquire what he thought about the possibility of an SLS cancelation.  We talked about the possibility of canceling the SLS project due to economic issues with the government.  Jeff also spoke about XCOR, ULA, Rocketdyne, pumps, and lower cost options with NewSpace companies.  Charles Pooley called in to talk about the Indian Mars mission, the 4 stage PSLV rocket, and his forthcoming book due out before the end of the year.  Tim sent in a STEM article & he called so we talked about the article but both of us did not think much of the author’s comments on the subject.  Next up was Doug from Southern California regarding articles about Bigelow and Lunar Cots.  The use of SLS was discussed for commercial missions or public/private partnerships and I parted company from his analysis and conclusions.  The articles suggested by Doug included www.parabolicarc.com/2013/11/12/50647 and www.newspacejournal.com/2013/11/12/bigelow-report-calls-for-use-of-cots-model-for-cislunar-transportation.  As frequent listeners know, Doug is a strong advocate of lunar cots.  I also asked him what the profitable commercial mission would for lunar cots.  Mostly Doug talked about selling rides to NASA except with the SLS, they would be using a gov. vehicle. It’s an interesting discussion.  What do you think about the ideas we talked about?  Andrew from Tucson was our last caller and we learned he has been busy with precision tool and engineering for rocket parts.  We also talked about the need for cultural changes in the country and he talked specifics in this area, not with generalizations.  We also talked about astronomy, career paths, and telescopes.

We welcomed Dr. Taylor Dark to the program to discuss his chapter on space advocacy, “Reclaiming The Future: Space Advocacy And The Idea Of Progress.” Dr. Dark’s chapter appeared in a NASA book around 2007, The Societal Impact of Spaceflight.  The .pdf version is a free download at http://history.nasa.gov/sp4801-part1.pdf.  You can read Dr. Dark’s chapter at www.taylordark.com/NASA%20Chapter.pdf.  For more information about our guest, please visit his website, www.taylordark.com. I urge you to read Dr. Dark’s chapter before listening to this program.  During the first segment of our 2 hour 1 minute discussion, Dr. Dark told us about his space advocacy background given that he started the first high school L5 organization when he was around 14 years old.  From there, we talked about aspects of space advocacy and specific personalities such as Dr. Zubrin and Taylor’s early fascination with O’Neill colonies.  He then described his shift to a different view of advocacy during his undergraduate college days.  Taylor went into detail about advocacy being connected to the idea of progress for humanity and listed three major space advocacy claims: (1) No limits on growth or human capacity; (2) All good things go together meaning elements of progress are linked together & are reinforcing; (3) Innate Directionality meaning progress is always probable.  He discussed these claims on air but he goes into them in detail in his chapter.  The utopian or messianic view of some advocates was discussed.  Dr. Dark also pointed out that space advocacy was not the only outlet for science, progress for humanity, etc.  Next, he talked about the frontier idea which he said was a weak argument.  He cited many national experiences that had had no frontier and have done well with their space program.  A listener asked our guest for his three top space arguments which were space exploration for more understanding of the universe, planetary defense of potential NEO hits, & commercial activity that was really profitable.  John called in to talk about the need for low cost space access and RLVs which would in turn cause space advocates to engage in lots of potentially profitable ventures. 

In our second segment, Doug called to talk about the probable costs of the O’Neill vision including the lunar base, SSP, & the habitat.  He suggested space tourism was a potential scalable profitable venture and he talked about space and lunar settlement.  Doug also talked about propellant in Earth orbit and satellites from LEO to GEO.  I spoke with Doug about project financing and how commercial or public sector project viability is analyzed which was different from what Doug talked about.  Taylor suggested that advocates don’t typically engage in something like project financing, instead opting for solutions that fit their advocacy agenda.  Taylor talked about the challenges of many advocacy claims including HE3 and fusion and the need for large space settlements.  As we were ending the discussion, Taylor was asked about the possible impact of microbial life being discovered, past or present, or ET.  We also talked about advocacy for inspiration & education and the impact of the Chinese program on advocacy and civil/commercial space. 

Please post comments/questions on The Space Show blog above. Dr. Dark can be reached through his website.

We welcomed Dr. Haym Benaroya, mechanical and aerospace engineer at Rutgers University, back to the show to discuss lunar thermal and seismic analysis, space policy, human spaceflight, Mars, and more.  Our intention was to do a one hour program but due to incoming listener phone calls, this program lasted for 1 hour 39 minutes without a break!  In addition, the discussion at times with callers was quite heated, very passionate and ripe with disagreement, especially between callers and myself.  Frankly, there were times I just had enough of the gloom and doom and the la la land fantasy stuff so I blasted back on what the callers more than the guest were saying.  We started the program with an update from Dr. Benaroya on thermal and seismic analysis of lunar data collected from sensors left on the Moon by the Apollo missions.  The data has been run through new models for up to date processing.  As it turns out, for seismic activity, an igloo like structure which Dr. Benaroya described is probably the best for the habitat. Also, he said only flimsy items such as an antenna would like be risky structures due to lunar seismic activity.  I asked him to compare lunar seismic activity to the seismic activity of California and Japan.  We have it much worse here on Earth!  We talked about radiation issues & Haym suggested about 10 feet of regolith on the top of the hab would probably be OK other than for a solar event.  He also said much more data was needed for actual lunar structural engineering.  I asked him what the first lunar settlers would do during their day and this took us to HSF to Mars issues, microgravity concerns, and the Moon as a stepping stone to Mars.  John Hunt was the first of the callers, focusing on policy with the politicians.  Haym talked 3D printing with him, then I asked John if the program he was describing could be done in 10 years.  After forcing him to provide us with a yes no answer, he said no. Haym said the same but both agreed technology was not the problem, leadership was the problem.  We talked the need for profits for private ventures and opened up public/private partnerships for discussion on the show.  I asked both how to start implementing their plans & that was the opening salvo of the fireworks that unfolded for the rest of the show.  Doug called next and talked about his ideas for what astronauts on the Moon would do and his lunar development ideas.  I then challenged both caller and guest to outline their steps for making their happen.  I thought their implementation plans were severely lacking and opened up on each of them but more so on Doug for the balance of his call.  Haym said the first step was to rebuild U.S. launch capabilities. Doug had a different first step & talked about government funding as in a private/public partnership similar to what SpaceX has with NASA for Falcon.  I asked Dough how he intended to sell the importance & value of the program he suggested to those controlling policy and funding.  See what you think of this discussion & post your comments on our blog.  After Doug cleared the line, Charles Pooley called in & at one time I said he was the longest playing broken record in Space Show history! I told him he was full of doom and gloom and other people see things differently and I did not want is view of things to be right or prevail, suggesting others see things differently than he does. Again, your comments are welcome.  Near the end, I simply was rejecting the “dismal situation” facing our space program. While Haym agreed that things were not good today, he talked about how he inspires and works with his students so they can create a positive space environment during their careers and for our future.  Just before the show ended, Tim called at the last minute and I promised to send him a Timex given his rotten sense of timing show after show. With Tim, we talked propulsion, Zubrin’s thoughts on going to the Moon, & the two private Mars missions on the drawing board.  In his concluding remarks, Haym explained why he was not supportive of either Inspiration Mars or Mars One.

Please post your comments/questions on The Space Show blog. Haym can be emailed through me or his Rutgers website.

We welcomed Trent Waddington to the program to discuss his take on the recently concluded NewSpace 2013 Conference.  Check out the conference website for information, video archives and more:  http://newspace.spacefrontier.org.  In the first segment of this 2 hour five minute program, Trent went day by day, speaker and panel in his critique of the NewSpace Conference as he took elaborate notes during the sessions.  For this analysis, Trent commented on most of the programming starting out with his initial comments on public/private partnerships & the successful role of the Space Frontier Foundation (SFF) over the years in influence and possibly winning in the commercial space policy debate.  Rather than telling you what Trent had to say about the speakers and panels, I urge you to listen to his comments so nothing is taken out of context in terms of what he said and thought about conference specifics.  During the first segment, Trent covered the first two days of the conference.

In the second segment, Trent started with the early morning talk given by Rick Tumlinson, then the talk about 3D printing regarding Made in Space, then we talked about the video the Foundation made, “There Is Another Way,” to support the Foundation’s perspective of commercial space development, heavy lift, etc.  You can see the 6 minute plus video at http://spacefrontier.org/thereisanotherway.  I read one of the Foundation’s promotion letters regarding the video and then Trent and I discussed it.  I reported on the feedback I’ve received via email since the video was first shown at the conference Saturday morning up to the start of this Space Show program.  Trent had a different take on the video from having seen it at the conference and also having talked to those present for their perspectives.  I urge each of you to watch it. Post your comments on it on The Space Show blog.  After the video discussion, Trent commented on the balance of conference speakers throughout the day, then he reported on space work in Australia which focuses on research and on scram jet development and testing.  His conference conclusions and assessments were interesting, including his use of the term “NewSpace Fanatics.”  Listeners asked him for his takeaways from the conference for which he offered us three so don’t miss what he had to say.  When Trent left San Jose, he drove to Hawthorne and toured SpaceX.  He had much to say about touring SpaceX which I must say, having done it several times myself, is really impressive and inspiring.

If you have comments and questions for Trent, post them on The Space Show blog.  You can email Trent through me.

Guest:  Frank Stratford.  Topics:  Commercial space and space travel business models and revenue generation.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://thespaceshow.wordpress.com.  Comments and questions should be relevant to the specific Space Show program.

We welcomed Frank Stratford back to the program to discuss various commercial space business models, including nonspace revenue generating goals and objectives.  Frank is the founder of MarsDrive so for more information, visit their website at www.marsdrive.com.  During the first segment of our 1 hour 42 minute program, Frank introduced us to the topic in his April 22, 2013 Space Review article, “The Business of Space Travel” (www.thespacereview.com/article/2281/1).  Frank talked about the need to generate nonspace revenue while building up the space company & space revenue R&D, activities, & markets.  He cited SpaceX, Bigelow, & Blue Origins as examples.  This led to a discussion about markets & financing, plus estimated costs for a human spaceflight mission to Mars. Frank compared the Mars One $6 billion estimate to his own estimate from his research to be $15 billion.  Our first caller asked if big name investors associated with these early commercial space ventures created an expectation of success and may in fact turn out to not have been such a good idea.  The detailed discussion included ROI, Stratolaunch and the revenue cycle gap from up front/early capital needs to revenue generation later on in the project’s cycle.  We talked about the nonprofit or charity model and Inspiration Mars came to mind.  I entered the discussion with comments about the need for repeat customers, a commercial space success to model, unrealistic assumptions, the lack of due diligence, and the difficulty in cost estimates, especially when the cost of getting to the destination (the Moon for example) is unknown at this time.  Surrey Space & Technology was also brought up as an example of a good business to model.

In the second segment, our called pointed out a Moon & Back interview with Robert Bigelow in which our caller said Bob said he went into the r/e business to fund his space activities.  Later, he email in additional comments suggesting that just because a space venture or idea is not funded does not mean it’s a bad idea or concept. He then advocated NASA support such as with COTS and Commercial Crew.  Public/private partnerships were advocated as a good way to move forward with space development and exploration.  Frank was then asked if a failed commercial project would hurt the industry.  He said it was possible.  Another question came in regarding paying attention to human factors and if solutions would be available at the same time as engineering technology, financing, and maybe markets.  Frank said only if work moved forward on human factor solutions at the same time and at a similar rate.  He also advocated his own organization working the problems.  Listen to his reasoning behind this.  As the program was nearing close, Frank was asked if Curiosity found proof of life in the past or now, even the most basic life, if it would make HSF to Mars more of a priority.  Don’t miss Frank’s response.  In summary, Frank talked about the need for continuous incremental development.
