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 Emily Lakdawalla to the program to discuss space science missions, The Planetary Society, space & outer planet geology.  During the first segment of our 90 minute program, Emily went over her background and how she came to have an interest in space and in particular space science and geology.  Some of our topics included the tectonics of Venus, asteroid mining, her interest in the outer planets of the solar system, and science missions either ongoing or to be conducted in the future.  I mentioned a possible Europa mission which led to a Europa discussion and Emily talking about the ESA JUICE mission (JUpiter ICy moons Explorer).  We talked about being able to cut the travel time to the outer planets for science missions and our guest mentioned the possible use of SLS to do that.  Don’t miss this discussion.  Also in this segment, we talked about upcoming comet and asteroid mission, then we switched gears to discuss robotic challenges.  Here, Emily pointed out the time lag for communications to Mars and beyond makes telerobotic control difficult at best.  We talked about having a Mars orbiter to control surface robots.  Were we doing this, the robots could be simpler as they would not need as much autonomous capabilities as they need now based on Earth communications.  Emily told us about Planetary Society projects and programs, we talked about man in the street interviews regarding space & our guest shared her experiences with us when Shuttle Endeavour came to Los Angeles.  Near the end of this long segment, Kepler came up, questions came up about Earth geology being similar to the geology of the planets, the lack of fossil fuels on other planets, then Doug called with a question about coalition building & the NASA science budget.  As the segment ended, we asked Emily about robotic exploration as compared to having a human geologist on the surface of the planet. BJohn from Sweden sent us emails about Curiosity on Mars and Venus.

In our second segment, we talked about relevant time spans and how missions get prioritized.  Emily went over the Venus challenges.  She was asked if the Planetary Society would try another Phobos-Grunt mission and we talked about their project, the Mars Microphone to bring back to Earth the sounds from Mars.  Toward the end of the program, Emily was asked about the importance of lowering launch costs for science missions and the promotion of space advocacy.

Please post comments/questions on TSS blog above.  You can reach Emily through The Planetary Society or me.

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.

Please post your comments/questions on The Space Show blog above.  You can reach any of our callers/participants through 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 Dr. Philip Metzger to the program to discuss the topic of a coming space resource revolution because of the prospects for a rapid advancement of robotic industry in space.  Please visit his website at www.philipmetzger.com. During our first segment of this two hour five minute program, Dr. Metzger explained the need for space resource usage as a result of a growing Earth population, increasing energy demands, industrialization & an overall feeling of being “squeezed” regarding future demand and resource usage.  From this point, he took us through the technologies, advancements and some visionary plans for setting up a commercial industry in space for space mining robotics and ISRU technologies which are available today.  Dr. Metzger was clear in telling us that the NASA charter was about exploration, not starting up space industry.  We then talked about the ways that industry can access the advance technology created by the NASA exploration and science programs.  Our guest provided us with several robotic examples, including the possibility of making heat shields from Phobos materials which could go a long way toward making a Mars mission affordable.  We talked about technology readiness levels, TRL 1-9.  Phil explained what the various levels meant & how the technology development is passed on to the next development group as the level advances.  I asked our guest to describe a typical day in his lab.  Starting at 6:45AM, Dr. Metzger described his duties and functions and those of the rest of the lab workers.  As you will hear, it’s a mixture of administrative, design, computer work, testing, retesting, & equipment manufacturing.  3D Printing was discussed in some detail and was actually a discussion topic throughout the entire program.  We talked about our being able to repair robotics as compared to building the robotics to avoid needing repair.  Listener Mike sent in an email to inquire about 3D printing, teleoperated & AI robotics for self sustaining lunar/asteroid economies. He also wanted to know how human space exploration fit into the robotic model.  Phil had much to say in response to Mike so don’t miss this discussion. Near the end of this segment, we talked about robotics & the communications time delay, even for the Moon, and what this means for HSF & robotic development. Another concept introduced to us was that of self-sustaining robots that do not need to continue being launched to their destination! Near the end of this segment, Phil introduced us to Lizard Scale Robotics & the different categories going up the scale of robotic development to the top level human scale.

In our second segment, Doug called in from S. California to inquire about starting an affordable industry, financing, and the use of lunar propellant ice.  This took us to a discussion of setting up profitable ventures for space industry development. Phil talked about a new spaceport concept starting with spaceports here on the ground, then in LEO, on the Moon, & then moving out to Phobos.  For a profitable venture, he did say the time line was still too long for capital investment so we discussed public/private partnerships. Also in this segment, we talked hardware designs, the need to start with low technology, even clumsy robots and evolve upward, but avoiding launches & most everything being made in space. We talked about launch capabilities, heavy lift, & getting a specific mass to where it needed to go.  Closing the business case came up & our guest talked about the old “impoverished view” as compared to a new, expanded, multi-potential global view. Don’t miss this discussion.  Mike sent in another note about what it might mean to be second & the value of the exponential potential.  Phil took us through this discussion which made it crystal clear why maintaining our space leadership or being part of it on an international partnership level was so important for our future.  In this context, Dr. Metzger talked about widespread participation in space development for multiple co-owners.

Guests:  John Batchelor, Dr. Chris Impey, Dr. David Livingston.  Topics:  The origins of our Moon, life on Mars, Earth analogs to Mars.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming.

Please visit the John Batchelor Show website for more information about this fine program, www.johnbatchelorshow.com. The topics in this 11 minute segment focused on the origins of our Moon and finding microbial life on Mars.  We talked about the lunar impact theory and why it is still preferable to competing theories for the origins of our Moon.  After exploring the lunar origin theories, we focused on finding microbial life on Mars and talked about Earth analogs including asteroid craters, the Antarctic dry valleys, methane plus a few others.  Toward the end of the segment, John asked Chris about our technology for finding life, comparing what robots of today and the near future can do versus what humans can do at this time.  Chris provided a most interesting response, including a brief analysis of the cost benefits of each type of mission.  If you have questions or comments, please post them on The Space Show blog.  If you would like to send an email to either Mr. Batchelor or Dr. Impey, do so through me at drspace@thespaceshow.com and I will forward it for you.

Robert (Bob) Zimmerman, Monday, 2-13-12

Guest: Robert (Bob) Zimmerman.  Topics: NASA FY13 budget & space policy. White Nose Syndrome bat update.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com.  Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright.  We welcomed Bob Zimmerman back to the program for his preliminary analysis of the NASA portion of the FY13 budget just released by the White House.  You can obtain more information about Mr. Zimmerman and the issues he writes about at his blog, http://behindtheblack.com.  Bob also provided an analysis of the NASA budget at http://behindtheblack.com/behind-the-black/essays-and-commentaries/a-transitional-budget. Bob started out by saying the NASA part of the budget was flat.  That said, he also said the Mars and planetary programs faced serious cuts.  He pointed out that missions in progress were still being funded, new missions such as the EuroMars missions were being scrapped though in the case of Mars, a new program was being created, the Mars Next Decade Program.  Bob went on to say the astronomy budget was being squeezed to finish the James Webb Space Telescope (JWST) which has its own line item in the budget.  The JWST was decimating the astronomy budget. He pointed out that the Kepler Space Telescope (KST) was being zeroed out in another year or so after it has completed its primary mission.  Turning to manned space, Bob described it as contradictory.  Commercial Crew would receive $830 million but of course congress may change that.  Also, SLS and Orion continue getting around $3 billion.  Bob talked about the flight plan for SLS & Orion and like many others, predicted the program would ultimately be cancelled.  Bob received lots of listener questions by email & phone addressing topics including a nuclear rocket, Mars Direct, DOD space funding issues, and the PR value for NASA for the HSF program.  Bob then suggested that history has shown that if the HSF program suffers, all of NASA suffers and pointed out that is happening now. Later, Marshall called to suggest that ESA might not be able to fund their part of the Mars programs due to European economic problems.  Bob speculated that our cutting participation may actually have been in anticipation of this to avoid problems down the road because of the European economic woes.  At the end of this segment, we talked about the successful European Vega rocket launch. 

In segment two, Bob talked about new information regarding sun spots and climate per a recently reviewed paper.  Check out the story at http://behindtheblack.com/behind-the-black/essays-and-commentaries/the-link-between-sunspots-and-climate. We also talked about the 2012 plan proposed by the Large Hadron Collider (LHC) in its search for Higgs boson.  Listeners brought up the nuclear rocket, the Cassini mission in the budget, and more on JWST.  Bob also reported some new developments with LightSquared, the FCC, and GPS issues.  Tim called in with questions about the sun and an electro magnetic pulse (EMP). As the program ended, I asked Bob for another update on the White Nose Syndrome which has killed lots of bats in the northeast.  Bob closed by saying the upcoming Falcon 9 & Dragon launch plus the Orbital Antares launch may prove to be the most important events of the year.  He said they were risky ventures, especially the Antares launch and program.
