We welcomed Dr. Doug Plata back to the show to discuss his Return to the Moon (RTM) segment within the Space Access Society (SAS) meeting last week in Phoenix, plus space policy and other topical issues.  Due to a server glitch and phone line issues in connecting with Doug, this 100 minute show does not have a break as we took our breaks to reconnect to the server and Doug.  As we started out our discussion, Doug gave a shout out to Space Access and to the founder of it, Henry Vanderbilt.  Doug then turned his attention to his Return to the Moon conference within the Space Access Society conference. Doug also provided us with his specific definition for Lunar Cots.   He mentioned the key speakers including Jeff Greason, Jim Muncy, Erik Seedhouse, and Dave Masten.  He summarized each of their presentations, plus he mentioned the SAS lead in speaker to his segment, Dennis Stone of NASA JSC, and the speaker after the RTM segment, Bruce Pittman.  Doug said both speakers were so on topic that in reality they could have easily been part of the RTM segment.  Doug discussed lunar lander options, powering rovers on the lunar surface, especially after taking a call from Jon in New Jersey.  He went into some detail on the presentations within the RTM segment.  BJohn in Sweden asked several quality questions via email so pay attention to them when I read them on air.  Space policy and politics came u as Doug was concerned that a NASA RTM effort might be part of a larger international effort, not a public private partnership effort and it would result in footprints on the Moon all over again without sustainability.  Near the end of the program, he discussed this with Dr. Lurio who called in to raise issues around Doug’s comments & concern.  Doug also reported on the rest of SAS including the Virgin Galactic talk/update.  Again, I apologize for the streaming and phone line issues early in this show.

We welcomed Bruce Pittman back to the show to discuss the upcoming ISDC 2015 Conference to be held in Toronto, Canada from May 20-24, 2015.  During our one hour program, Bruce talked about ISDC events in general, then the Toronto location for this year’s conference and the conference location, the Hyatt Regency Toronto.  ISDC is a multi-track conference with workshops and an excellent exhibit hall.  For more information, registration, hotel bookings, visit the ISDC 2015 website, http://isdc2015.nss.org/wordpress.  From time to time during our discussion, Bruce mentioned a separate event needing separate registration, The Space Innovation Business Summit (http://isdc2015.nss.org/wordpress/the-space-innovation-business-summit).  Bruce also went over the list of the keynote speakers, all of which are listed on the ISDC 2015 website.  In fact, I strongly suggest you open the website and follow along with us during our discussion about the event.  Bruce also said there would be upwards of 300 students present from around the world as a result of the Space Settlement Contest.  Bruce highlighted both India and Romania for their student participation in the contest and ISDC 2015.  Listeners asked many conference questions including networking, Q&A sessions, and inquiring if there was both a propulsion track topic and a human factors track topic.  Toward the end of our discussion we took a call from Doug regarding EML2, depots, fuel, Mars transportation, etc.  If you are planning to attend, remember you need a passport to enter Canada. Reserve early for the hotel, the conference and your transportation.  ISDC is a terrific event. If you attend, I want to hear from you about it on The Space Show.

We welcomed back Brent Sherwood for updates to his human spaceflight analysis work previously presented on The Space Show.  During the first segment of our 1 hour 48 minute discussion, Brent started out with a brief discussion on scientific missions and the year 2015 being the Year of the Dwarf Planet.  He talked about the Dawn Mission and Ceres, New Horizons and Pluto, and the oceans on the outer planet moons.  Exoplanets and the habitable zone were also part of this discussion which included an assessment of just how our knowledge has changed regarding the compositing of the solar system.  To redirect the conversation to the purpose of today’s show, human spaceflight (HSF), I asked Brent when we would see HSF beyond LEO (BLEO). I asked about what seemed to be a new space advocacy push for space settlement. Brent then examined why HSF and referred us to his earlier work and the four reasons for HSF which were explore, exploit resources, to experience space, and settlement.  He said settlement was clearly part of the debate, talked about earlier workshops which would avoid the topic and then spoke to the recent Pioneering Space meeting held in Washington, DC where there was a consensus reach for space settlement.  He had good things to say about the meeting and the consensus resolution and talked about the broad space industry representation at the meeting as it was not just NewSpace.  Don’t miss what he had to say about it and space settlement.  Brent was also asked if our National Space Policy Act needed to be amended to reflect space settlement as the official goal of NASA.  Later, he was asked about the stepping stone or incremental approach to HSF development.  He supported this approach, spoke to the challenges for HSF such as life support and more.  As we were closing out the first segment, he offered us valuable insights on this topic so don’t miss what he had to say.

In the second segment, John from Florida called in to ask about grand space visions like an O’Neill orbital colony.  Brent proceeded to discuss grandiose visions in the context of how challenging they were plus their replacement cost.  Here, he used the replacement cost for Manhattan as an example of what he was talking about.  He cited a different type of example, the NASA Ames Space Settlement Contest that had nearly a thousand entries this year from 21 countries with the winner writing a 247 page grand space vision report.  Brent also spoke to the inspiration factor when talking about this contest.  A variety of listener emails were read on air for Brent to respond to, then I asked him if he thought Mars was the Holy Grail for HSF.  He said no so don’t miss why he said that.  He was asked about nuclear propulsion, then we talked about returning to the Moon , cislunar development, and then back to Martian settlement.  He was asked about going to the moons of Mars and he said there were two ways to settle Deimos.  Don’t miss his comments here either.  Near the end of the program, he said the physics of HSF were good but the problem was centered in being grounded in what he called program or budget math.  The budget math for HSF simply does not work, especially for a commercial venture.  He closed on the reality check of being grounded in budget math and the difficulty in going to Mars with humans.

We welcomed Eric Berger to the program for a wide ranging discussion on US space policy, NASA, our space future, commercial space and more.  During the first segment of our 1 hour 37 minute show, Eric started the discussion by talking about his early interest in space, his contacting NASA as a child, getting back a great set of photos and other information and being hooked and excited about space ever since.  Some of the early topics in this segment included his surprise that we are not yet beyond low earth orbit with manned spaceflight, then he addressed why it is taking so long to go to Mars , why Mars is the next big step for humans and why going to Mars is so hard.  In his discussion of these topics, he referenced Elon Musk and the SpaceX Mars plans, even Mars One.  I asked Eric for his perspective on the NASA ARM mission which led to one of many discussion of NASA budget constraints and the idea that this or that project is all that can be done within the budget permitted by Congress.  Eric started getting lots of listener emails.  Jenkins wrote in saying that its not the budget that is the problems, the choices we make as a country regarding how we spend money that is the problem.  Eric then referenced the human spaceflight study released last year by the NRC regarding the likelihood that we will be living with tight NASA budgets for the foreseeable future.  Paul in New Mexico asked Eric about the impact of commercial space on policy and NASA.  Eric said it was an important impact so don’t miss his full statement.  Later in the segment, we talked about his seven part “Adrift” series last year and I asked him what his biggest surprise was in researching the articles for the series.  He said it was finding a shift in his view on SLS and that SLS could very well be an important part of our spaceflight future but that it needs to be funded to launch real programs.  He also said that maybe Falcon Heavy could do most of what SLS could do, especially in the Earth-Moon systems but that remains to be seen.  We then talked about the time it took to do various parts of Apollo compared to how much time it takes to do just about anything in space today.  Michael Listner called to talk about needing both NASA & commercial space and some realities involved in policy and space issues.  As the segment was ending, a Portland listener asked if competition with China might develop and force the US to spend more and do more in space.  Don’t miss Eric’s answer.

In the second segment, Eric was asked about space settlement being the goal and the purpose of our National Space Policy through a change in law per March Storm and other groups who are advocating this.  Eric was OK with space settlement but listen to his comments for the full context of his message.  He also said it was hard to figure out what to do with SLS but that some changes might be a full ten years out from today.  We talked about space technology advancements and then Gerald Driggers called in to say we had lots more work to do. For example, we talked about the need to fly a centrifuge in space to determine the gravity RX for humans.  The issue of the lack of space leadership came up from the White House down to the congress.  Many times our guest said it would take a change in leadership to get a change in space leadership but that just changing leadership does not mean the new leader(s) will care about or prioritize space.  Regarding commercial space, he went a bit deeper in this segment.  He said there was lots of commercial space activity but that NASA was still the center of it.  He made the case for the industry needing a broader base than just NASA.  I asked about a Europa mission and another listener asked he could articulate the Senator Ted Cruz view on space policy.  We talked timelines for humans to Mars and for a return to the Moon, he was asked if NASA should be eliminated in favor for a return to something like the old NACA, then Benny in Denver asked about the Texas spaceport facilities being developed for SpaceX and the Blue Origin facility.  As we neared the end of the program, Eric again stressed the difficulty in going to Mars, he looked back at our space history including Gemini 4, and he talked about the Obama policy from 2010 about not going back to the Moon though many in NASA do want to go back to the moon.  Bottom line was Mars around 2050.

We welcomed Dr. John Jurist and Kobi Hudson to the program to discuss their recent experiences at the Orbital ATK 5 segment booster test in Utah and the ISS algae experiment Kobi and his teammates are working on at this time.  During the first segment of our 1 hour 58 minute discussion, John and Kobi talked about viewing the Orbital ATK 5 segment booster test this past March in Utah.  John has attended all the 5 segment booster tests but this was the first one for Kobi who is one of John’s students at Rocky Mountain College in Billings, MT.  Kobi described the test, what it looked like and how it felt from the viewing area, the networking opportunities he had with those attending the test including many executives from across our aerospace industry & NASA.  I asked John and Kobi if they sensed that the Orbital ATK team was aware of the controversy surrounding the final destination for the booster, SLS.  We talked about this for several minutes.  I think you will find what both John and Kobi had to say about this to be very interesting.  This discussion took us into an SLS discussion but from a slightly different perspective than our usual Space Show SLS discussions.  A listener asked our guests if either of them noticed a cultural difference in the test team given the Orbital and ATK merger.  Kobi was asked if the test and the experience inspired him to want to work in the aerospace field which it did.

 

In the second segment, Marshall called to inquire about the use of liquid rocket motors as compared to solids and wanted to know which type was more efficient. Both John and Marshall seemed to agree that it might depend on which type of propulsion system gets more launches and usage though the solids are far simpler.  As part of this discussion, the political dimensions of decision making were brought up as they play a role in the propulsion system and thus influence efficiencies.  Next, we turned to Kobi to explain to us the algae experiment he and others are working and which will fly to the ISS on the SpaceX 7 launch.  Behind this experiment is the goal of testing how well algae grows and how much carbon dioxide it consumes in a zero-gravity environment.  They want to see if it can influence the presence of oxygen in the spaceship.  The algae is grown in an agar solid media.  Kobi went into details on this experiment which I believe you will find of interest. When the team gets the data back from the 28 day test, Kobi will come back to the show to update us on what they found out.  Later in the segment, SLS John called in to follow up on our earlier SLS conversation and the proposed NASA ARM.  Several listener questions came in by email regarding both the issue of solids vs. liquids and the algae experiment.  Kobi also got a question or two about this work on the Firebird cubesat program.  He said it used a polar orbit , was then asked if cubesats could go to the Moon or elsewhere and he said probably but challenging. Doug called to talk closed loop life support and related issues.  The last question came from a high school senior asking Kobi about the need to attend a Tier One school and the consequences for going to a school not as well known and not as highly ranked.  All three of us, Kobi, myself, and John responded to this question saying about the same thing but in different words.  Both John and Kobi offered concluding comments you don’t want to miss.

We welcomed back Rand Simberg to the program. During the first segment of our 100 minute program, Rand discussed the Falcon 9 launch and barge landing attempt of the first stage. Before he finished his discussion, Dr. Lurio called in and joined in on the speculation as to why the landing was unsuccessful. Both Rand and Charles thought it might be wind but as you will hear, that was just their opinion. Next, the two of them turned to the ULA announcement about the Vulcan rocket and their plans to recover in air from a supersonic parachute using a helicopter. They want to recover the rocket’s main engine. This discussion between Charles and Rand dominated the first segment of the program. Near the end of the first segment, I asked Rand about the ARM and it being redirected to Mars and Phobos. Rand had much to say about this so don’t miss it.

In the second segment, in response to earlier comments made by Rand in the first segment, Sally sent in a note asking if the next NASA administrator might make a difference and actually matter. Again, don’t miss what Rand had to say about this plus bipartisanship and the work of Congressman Dana Rohrabacher who wants to change the our space policy to one of having the main purpose to settle space. Rand also said he would personally like to “ban” the phrase space exploration. Listen to his explanation on this point. Rand was asked about the Moon-Mars debate which he thought was absurd given that the issue was not about destinations but getting the needed infrastructure in space so one can go anywhere. Without the infrastructure, even a gravity lab, talking destinations makes no sense. Due to a few listener questions, Rand also had some choice comments for Mars One. Another listener asked Rand what parts of the commercial space industry impressed him the most. This led to a discussion about suborbital flight and markets. Becky asked him about his Transterrestrial blog (http://www.transterrestrial.com) and the non-space portion of it, I asked him about military space and then Tim called to talk about affordable small sat launches and to inquire if we were embarking on a space race over low cost launch opportunities that may be emerging. Rand also talked about the upcoming Space Access Society meeting and the talk he plans to give at the event. Rhonda in Petaluma asked Rand what caused his transition from traditional aerospace to NewSpace. Don’t miss this, it is really interesting.

Please post your comments/questions on TSS blog above. You can reach Rand through his blog or me.

We welcomed Dr. Erik Conway to the show to discuss his new book, “Exploration and Engineering: The Jet Propulsion Laboratory and the Quest for Mars,” JPL history, engineering, Mars missions, and much more all from the historical perspective.  In the first segment of our 1 hour 28 minute discussion, I asked Dr. Conway how JPL engineers did things that led to major Mars exploration breakthroughs.  He cited the Mars Pathfinder mission as an example and the decision to use airbags for the landing.  Dr. Conway took us through the process, the cost benefit analysis of the decision and the role played by budgets, the engineers, policy makers, and others contributing to the mission.  Our guest provided us with other examples as well from other Mars projects and missions.  Listeners asked our guest about human missions.  Here, Dr. Conway had much to say throughout our discussion focusing on the fact that humans are dirty with bacteria, planetary protection is a priority, and there is zero risk or near zero risk for a human mission.  When asked if the Moon required the same planetary protection policies as Mars, he said no though in the early days of lunar exploration, it did.  I asked our guest about the roles played by policy makers and engineers and this resulted is a very interesting discussion. Don’t miss it.  Listener Barbara in Seattle asked our guest about Curiosity cost overruns and how that would be reported on in history.  This led to a discussion about the impact of management and others on the initial design and budgets.  Later, Dr. Conway was asked why JPL had a focus on Mars in the first place.  Doug called in to ask about the humans vs. robot debate for science.  Don’t miss the response to this question by our guest.  Doug also brought up the issue of finding past or present life on Mars and what that might mean for future  Mars missions.  Dr. Conway agreed that probably all sides in the argument of avoiding Mars to avoid contaminating and disturbing life to the opposite perspective will be arguing the issues for a long time to come.  Dr. Conway addressed commercialization and while supporting reduced launch costs said the cost reduction needed to be magnitudes lower than even the lower costs of today.  Dwayne called and addressed planetary protection, then he turned his attention toward asking about the research opportunities at JPL for outside historical researchers.  Erik explained why these opportunities were limited, partly holding ITAR responsible.

In the second segment, Erik talked about the risk versus return on the costs.  He talked about there being almost zero tolerance for accidents and losses with Mars missions and human missions.  He also said the zero risk tolerance for these missions has been a significant cost driver.  Our guest had much to say on this subject with regards to Mars so don’t miss it as it covered most of the second segment. Later in this segment, Jake inquired about the early JPL history and its founders and their impact on the JPL of today.  Penny wanted to know about the Cal Tech-JPL relationship.  Dwayne sent in an email asking about the Faster, Better, Cheaper programs and what happened with the JPL programs using this approach.  This was an interesting way to wind up the show. As we were ending we learned that Goddard has no historian so their programs are not being recorded or document.  I sked Erik the difference in JPL and the APL.  Note how he explained the difference between the two labs, their risk tolerance, and decision process.

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. Tony Milligan to the show to discuss his new book, “Nobody Owns the Moon:  The Ethics of Space Exploitation.”  Note that at approximately 1 hour 47 minutes into the program we lost our guest.  I took a short break and was able to get him back with us for the final ten minutes of our 1 hour 58 minute discussion.  In the first segment of the show, Dr. Milligan introduced us to the book and the topic from a moral and ethical perspective.  He said that he was in the middle range from not wanting any space development activity for ethical reasons to uncontrolled commercial development as in free market activity.  He said we had an obligation to do it right but defining what right meant was challenging.  I asked him about enforcement and that turned out to be a significant discussion topic for most of our program.  I took an early call from Kris in Wyoming who challenged our guest on all levels given his wanting to put a thorium reactor on the Moon, dispose of thorium waste inside a crater, and fuel a lunar settlement.  Kris and Tony went back and forth on the issues, approvals that should be required, trivial versus non-trivial, who decides or makes the decisions.  Tony cited the Sphinx and Pyramids to make a point which Kris and others rejected during their give and take and the show.  One of the issues that kept coming up was that the celestial item in discussion had cultural significance which Tony worked to define.  Many emails were received and discussed regarding cultural significance issues, the comparisons to terrestrial monuments and a celestial body, plus the point that the development on the Moon or Mars would not be visible from Earth so why should it matter.  See if you agree with Dr. Milligan on the visibility issue.  We talked about Ch. 7 in his book on mining off world.  Trivial and non-trivial pursuits came up again as our guest would not be inclined to approve a trivial pursuit but if it was significant, it would probably be approved.  Of course who decides if a project is trivial or not and then attempts to enforce all of this remains an issue.  Michael Listner called in and largely supported our guest saying this discussion was highly relevant.  We also talked about the NASA ARM mission , lunar protection, and more.

In the second segment, Tim from Huntsville was our first caller. He misread the bio for our guest but wanted to talk about vandalism and other issues but they were descriptive used for another book written by Dr. Milligan.  More emails came in including from Doug wanting to know who or by what process the Moon was assigned value and are there other countries where one could go to do commercial activities in space without regard to the issues our guest was speaking about.  Don’t miss Tony’s response to both of Doug’s questions.  Kirk wanted to know if Tony thought there was a difference in speaking about these issues in Europe as compared to the U.S. , then Doug called to talk with Tony about striking a balance and getting Tony to say what he would and would not be willing to approve.  In this discussion the cultural value of the Moon came up as Doug asked if he would approve this or that project.  Of course this means that Tony, someone else or some organization would have the approval or disapproval power based on certain criteria that may or may not be objective or to the liking of the entrepreneur for reasons totally contrary to the project’s goals.  Doug talked about the rational man standard but even that can be subjective as everyone always believes they are being rational.  I used as an example the current nuclear talks with Iran.  From the Iranian perspective, their demands are rational and in keeping with their “rational man” standards but not ours.  Michael Listner emailed in about the Apollo landing sites NASA guidelines.  Other emails came in including one four part note from Ken.  Tony responded to Ken with one consolidated answer for all his four questions.  Perhaps Ken will post his questions on the blog though I read the email on air.  Tim called back about the time we lost Tony on the call. Tim wanted to talk about Common Heritage of Mankind and benefit sharing plus the UN but Tony was already off the call.  I paused the discussion to get Tony back on the line for the last ten minutes of our show.  When Tony came back on we talked about the differences in the Moon and Mars regarding ethical issues, settlement as being trivial or non-trivial, and that only non-trivial pursuits should be permitted.  In the end, our guest said his book was meant to open these discussions and that all sides should be represented and have a voice, even those poorer nations that cannot access or do anything with space though he did not say they should have an equal voice to the space fairing nations.  As the program was ending, I asked Dr. Milligan about his upcoming book which will be an edited volume on these issues featuring both sides to the argument.  For sure we will invited Dr. Milligan back when that book is available.

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

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