We welcomed Dr. James Dewar and Dr. John Jurist back to the show to discuss nuclear propulsion and rocket. During the first segment of our 1 hour 40 minute discussion, Both Dr. Dewar and Dr. Jurist talked about the nuclear rocket technology, fuel, cores, past experiences, and how best to modernize the nuclear rocket and move forward with new development. Most of the callers talked technology so this first segment is very technology heavy. Space attorney Michael Listner sent in emails suggesting it would never happen due to the regulatory side of things plus he provided us with the UN Committee on the Peaceful Uses of Outer Space policy on using nuclear power in space (www.unoosa.org/oosa/SpaceLaw/nps.html). Listener Kristopher spoke to our guests about core options and fuels. Check out this site that he sent us: http://www.projectrho.com/public_html/rocket/enginelist.php#ntrvapor. Toward the end of the first segment, I said that after the break the second segment would focus on what to do to make the nuclear rocket policy and to start the program and develop this form of advanced propulsion. Both Dr. Dewar and Dr. Jurist agreed.

In the second segment, we did focus on the need for leadership and organizational structure for developing the nuclear rocket and starting with nuclear propulsion. We had several callers and emails addressing how to sell a nuclear rocket program. Dr. Dewar talked about the economic benefits, jobs, opening up more of space to economic growth and access. I asked about chokepoints and both our guests suggested the biggest chokepoint was the absence of young, passionate, and competent leadership. Related issues that came included how best to get the support of congress as well as the American people, plus why a nuclear rocket was important and should be developed.

We welcomed Les Johnson back to the show to discuss his latest books on popular science & science fiction, solar sails, and much more. In the first segment of our 1 hour 45 minute show, Les began talking about solar sails and their use to go to go around our solar system and eventually to the stars.  There was much interest in the solar sail subject so Les gave us a terrific somewhat technical lesson on solar sails.  We fielded many listener questions and we all learned much about solar sails, their potential, today’s capabilities, materials used, and more.  This was  an exceptional discussion so don’t miss it as solar sails are a very exciting technology for robotic spacecraft.

In the second segment, Les mentioned the Lunar Flashlight and Scout missions.  I asked our guest about the track record for solar sail missions.  If the mission launch was a success, the solar sail mission has been pretty good but there have been issues with the launches on some of the past solar sail missions.  I also inquired about solar sail work, research, and interest around the world and with other space agencies.  A listener emailed wondering if the use of a solar sail made a satellite or a mission more vulnerable to an ASAT type weapon.  We switched gears to talk about the science fiction work Les has done with Ben Bova  regarding mars with his book “Rescue Mode.”  Les talked about his parameters when writing science fiction plus I asked him about the feedback he gets as an author from both his popular science books as compared to his sci-fi books.  You might be surprised by his answer.  Nuclear propulsion came up for discussion and a few listeners wanted to know the human spaceflight awareness level of people when he gives lectures on the topic.  Interstellar flight was discussed as was the movie “Interstellar.”  As we were moving toward closing the program, Less said he believes HSF is going through a golden age and he explained why.

Please post your comments/questions on TSS blog above.  You can email Les at the address he gave out, through his website at http://www.lesjohnsonauthor.com, or me.

Welcome to our first ever Space Show New Years Resolution and Wish List program.  During both segments of our 1 hour 48 minute discussion, listeners phoned in and emailed their wish list for space development projects for 2015 and even beyond.  During the first segment, Michael Listner started us off with a wish to see a space policy thinker type of website started to open and support a high level discussion on what our space policy should be.  He did not know how to implement the idea but we talked about some possibilities and he suggested a few participants.  Ideas are welcome.  We next heard from Jon in New Jersey who wanted to see Dream Chaser continue on to success along with commercial crew.  We talked about returning to the Moon and using the Moon as a stepping stone to Mars, plus various paths on the way to Mars.  Chris from Wyoming called in and suggested peace between all sides on the SLS debate.  We also talked about lowering launch and access to LEO costs and baby step methodology for getting to Mars.  He also wanted to see strong support and growth for the private sector.   John in Florida called with a wish list item of stopping throwing away the boosters.  He said his extended wish was for ULA, Orbital and others to begin working on reusability.

In the second segment, Andrew from Tucson called.  We talked about Kitt Peake and his projects with Jeff that he has been working on that he wants to continue,  including hardware demonstrationd.  Doug called from S. California and wants to publish his Cis Lunar One paper & move forward on his conference or TED talk concept.  He mentioned the need to spend less time posting on blogs and making more direct contact with leading space policy people.  Tim called wanting to see full Falcon 9 reusability among other things.  John from Ft. Worth called and said his wish list was for more SLS funding and to see a successful Falcon 9 first stage recovery landing on the barge.  Rick sent in emails about fusion energy and more, all of which I read on air.

Please post your comments/suggestions, and your own resolutions and your wish list on TSS blog above.  If you want to contact any of today’s participants, you can do so through me.

Welcome to our first Open Lines show for 2015.  During the first segment of our two hour program, I made a few topic suggestions as usual.  In my suggestions, I asked for listener ideas for both debate and webinar topics plus guests to invite for the suggested programming.  In the second segment listeners sent in many good suggestions but for those of you listening on archives, please send in more.  Sending in guest suggestions for the debate and webinar topics would be very helpful.  The first call was from John in Florida.  He wanted to talk about several topics including the SpaceX effort to land the first stage on the barge.  He also talked about Blue Atlas, Orion, Apollo, the NASA risk averseness and more.  Dr. Lurio called next to tell us where we could see photos of the barge after the crash landing of the first stage.  He also commented on news relating to Blue Origin & the Elon Musk interview on Bloomberg.com.

In the second segment, John called from Ft. Worth, commented on my comments re the email I read about the movie “The Principle” and his thoughts on doing a show with the people behind the movie.  John also asked about the SpaceX refurbishment plans for the first stage once they recover it.  Furthermore, he talked about Elon’s plan for satellites and more.  He asked if SpaceX might be overextending with all the ventures and projects it and Elon are involved in or announcing.  Several listeners sent in debate and webinar topic suggestions including nuclear propulsion, Is Mars The Goal, Mars vs. Europa, National Competition versus International Cooperation, Space Shuttle debates and more.  Pooley called in and we talked about Microlaunchers and other issues.

Please post your comments/questions on The Space Show blog above.  You can reach any of the participants through me at drspace@thespaceshow.com

We welcomed back Marc Millis to discuss the needed advanced physics for interstellar spaceflight plus his take on the new hit movie, “Interstellar.”  During our 90 minute program without a break, Marc debriefed us on his take on the science behind and involved with the new movie, “Interstellar.”  He said there were things about the science and the movie that he liked and that they did a good job with and other things that got a less than positive grade.  For example, he said the way the movie depicted the worm hole was nicely done & he explained why.  One area he did not like was the shuttle like craft being blasted to space on a Saturn V like vehicle but then going back and forth to the other planets.  He said this raised serious fuel issues & questions.  He also said the time dilation effects were confusing and inconsistent.  We talked about black holes, then Marc mentioned the Incessant Obsolescence Postulate which suggests that should a probe or occupied spaceship be launched to the stars, eventually a more modern one will pass it in the future enabling it to reach the destination a lot sooner than the initial ship.  Marc returned to discussing worm holes and the negative energy needed for them to be useful tools for interstellar spaceflight.  A listener from Boston asked about nuclear propulsion and if that was the advanced propulsion needed for interstellar flight.  Marc talked about both fission and fusion propulsion & their respective applicability & usefulness for interstellar flight.  SLS John called for an advanced physics discussion which included the inertial frame of reference and gravity discussion, Mach’s principle, the Equivalence principle, the Higgs particle and more.  This is a great discussion, don’t miss it.  Another listener asked Marc what the minimum advanced physics and propulsion would be to get started with an interstellar flight, then evolving to more advanced tools over time.  Marc outlined a plan he talked about earlier for doing small steps at a time as opposed to a giant leap needing far more advanced technology than what is available now or will be in the near future.  Another listener asked a similar question focusing on the minimum amount of knowledge needed to get started with interstellar spaceflight.  Pooley called in to talk about the Equivalence Principle.  Marc talked about the Tau Zero Foundation and its needs, and then Beth asked why we don’t focus on Mars or the clouds on Venus, both of which are more doable than interstellar flight.  Marc said we need to focus on both at the same time so don’t miss his excellent answer.

Please post your comments/questions on The Space Show blog above.  Marc can be reached through me.  To learn more, visit http://www.tauzero.aero.

We welcomed Bob Zimmerman back to the program for a wide ranging discussion of space news, space companies, projects, programs and more.  During the first segment of our two hour seven minute show, Bob started off promoting his book on Apollo 8, “Genesis” as we are coming up on the anniversary of this famous flight orbiting the Moon on Christmas eve at a distant time in our past.  After Bob’s infomercial was complete, he did have much to say about the everlasting importance of the Apollo 8 mission.  I asked Bob for end of the year space events to keep our eyes on so we talked about the upcoming SpaceX Falcon 9 launch and the attempt to recover the first stage on a barge as part of the SpaceX reusability plan.  We also talked about the Russian Angara rocket test flight.  A listener asked Bob for updates on the NTSB accident investigation for Virgin Galactic.  Bob also talked about SLS (it was yet another recurrent theme throughout the program) and as predicted, he had nothing good to say about it or Orion.  BJohn emailed us to ask about nuclear propulsion.  Both Bob and I responded and while we support it, there does not seem to be a business case for it or demand for it so there is no significant push to make it happen.  Marshall called to talk about the impact of falling oil prices on the space economy.  I had much to say about this as did Bob who in the end talked about trusting capitalism, freedom, and private enterprise to do the right thing.  We also talked about the impact of falling oil prices on the Russian economy, specifically their space program.  I then brought up the interest rate risk which is a huge potential danger for the US economy.  Luis emailed in about Falcon 9 prices of $5-7 million per a January 2014 Parabolic Arc article.  Note that this was clarified early in the next segment.

In segment two, Dr. Charles Lurio called to explain more about the SpaceX launch cost referenced by Luis in the previous segment.  Charles also talked about the Orbital effort to replace the Antares  rocket motor with another Russian motor, the RD 181.  Joe emailed in a note about the compact fusion plans for Lockheed.  Bob used the opportunity to criticize the large companies, their projects, pork, you name it.  Doug emailed in about some Boeing YouTube videos which Bob completely dismissed as having zero relevancy on anything.  Bob also took some slams at Orion and the recent test flight.  Next, we talked about the new announcement about Curiosity finding methane on Mars.  Bob added more to the story and said it was a wait and see situation but ultimately we would have to there to really answer questions about it.  SLS John called and said the program of record was going forward and made the point that for private enterprise to do something in space as Bob kept talking about, there needed to be a profit motive and he doubted that existed other than for some orbital and comsat missions.  Bob disagreed leaving the door open for a private company to pursue something not previously considered, again saying he trusted in the ingenuity of the private sector.  John reported that he had modeled the Falcon Heavy and could show it would take 53 metric tons to LEO.   Bob then talked about Falcon Heavy being cheaper than SLS (planned that is) so there really was no need for SLS.  Henry emailed a question about a possible Europa mission & Bob suggested if they would kill SLS, money could be directed to the planetary science department for things like a Europa mission plus they could still reduce the NASA budget.  In his concluding comments, Bob said he was skeptical about the suborbital industry and that its time had come and gone given the emerging orbital capsules and flight plans.  He concluded saying he was looking forward to the upcoming SpaceX launch abort tests.

Please post your comments/questions on TSS blog.  You can reach Bob through his website http://www.behindtheblack.com or me.

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.

Please post comments/questions on The Space Show blog.  You can reach the panel members through me.

In the first segment, Anatoly said the Russian program was at a crossroads wanting to develop new systems for the lunar mission & BLEO, building a new launch site ,Vostochny, while maintaining existing programs including the ISS.  He talked about programs falling behind schedule, proposed timelines followed by delays.  I asked him about the Russian tax system. Anatoly told us it was a flat tax system but that it was driven by their natural resources, especially energy.  In response to many questions, we learned that the Russian program has some struggles that make it similar to what is happening with NASA.  Anatoly talked about the new rocket Angara.  The Angara 5 is supposed to have its test flight on Dec. 25.  He also said there was a super SLS type rocket being planned but specifics were unknown at this time.  When asked for the biggest challenge to the Russian space program, he said it was the budget.  A listener asked about a possible joint China-Russian lunar or Mars program.  Anatoly suggested that were something like that to happen, China would probably be  behind it.  We talked some about the second printing of his book, “Russia In Space: The Past Explained, The Future Explored.”  Another listener wanted to know the origins of the Russian program.  We talked politics, sanctions, and the ISS relationship with NASA.  Returning their Proton rocket to flight was mentioned & Anatoly talked at length about their quality control problems.  SLS John called to talk about Russian nuclear propulsion.  The last caller of the segment, Richard Easton, talked about Russian GPS, GLONASS, timing & the early days with the Russian navy.

In the second segment, Anatoly talked about the Russian planetary program including EXOMARS with ESA for searching for life on Mars, their proposed HSF lunar program plus other missions on the planning table.  In response to a question, he did say their was lots of competition between the planetary side and HSF.  Roger wanted to know about becoming a cosmonaut, & Barbara wanted to know about space tourism to the Moon.  For the balance of the year, Anatoly said eyes were on the Dec. 25th test flight for the new Angara 5 heavy rocket.  Re the ISS, he expected it to remain as it is today.

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

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

We welcomed back to the program Dr. Mike Griffin.  During the first segment of our 90 minute discussion, Mike talked about human spaceflight (HSF) and the commercial space market.  He said exploration would be a government project or at least with government in the lead, especially if the commercial market was not there.  He threw water on the argument that our space policy was budget driven.  Instead, he talked about it being based on choices we make. It was not and is not about the money.  His comments throughout or discussion on this topic supported his argument.  He even said the cost of space for the U.S. taxpayer was around 15 cents/day.  This discussion evolved to one on the importance of leadership which we agreed was in short supply today.  Included in this discussion was Mike’s vision for our space policy & program, plus he explained its importance and value to our nation both today and for the future.  He spoke to the issue of what society wants and the choices it makes that shape our future.  Space should be part of our national policy debate and hopefully such a debate would enable quality choices to be made that keep us on the leadership edge with all nations.   Mike was asked who he thought would be next on the Moon and he said China.  We also talked about the private sector taking us back to the Moon with HSF.  He said that the private sector could do this, capital was not an issue, but for the private sector to do it there needs to be a closing of the business case which he did not see at this time.  SLS John called in & asked about space advocacy diversity which he said seemed to be at war with NASA & whatever the program of record might be.  Mike had much to say about this, especially about inefficiencies in government organizations and projects.  He also said if the private venture or industry cannot make money, then it should be a federal project. Many times during our discussion he said that there are things that a society should do just because they are hard & they don’t have to look good on the balance sheet.  John also asked about the RD-180 engine, Mike offered us his conclusion as to why we should be a new version of the RD-180 so that we do not continue being dependent on Russia for space related hardware, etc.  Later, he was asked about cislunar space development which he said should be a public enterprise.  He cited many examples and models supporting the public development of this important space infrastructure.  SLS was discussed.  Mike very clearly articulated the case for SLS today and again repeated that SLS future missions are about choices, not the budget.  Don’t miss his comments.  As the segment ended, Randy emailed a question asking for the rational & silver bullet for HSF.  In my opinion, Mike gave an excellent response to this question so don’t miss it.

In the second segment, Mike got some questions about NASA doing more R&D and even forming a NACA-like division or program.  We talked about NASA R&D, the need for a NACA-like program and more.  Dave, our caller, commented on leadership, then Bill in Denver emailed in a question about using fuel depots and smaller launch vehicles rather than heavy lift vehicles like SLS.  Again, Mike had much to say about heavy lift, including that while possible to do smaller vehicle launches., the numbers don’t pan out for efficiency.  You need to listen to this full discussion which also addressed some bogus assumptions regarding inefficient heavy lift decision making.  Nuclear propulsion and Vasimr came up, , then we again focused on vision that takes on big challenges because we can!  More was said on lunar colonies evolving to longer BLEO missions plus cislunar commerce, especially cislunar cargo missions.  Another listener asked about being dependent on the Russians for HSF to the ISS and if shuttle was retired too early.  Mike talked about having wanted to fly shuttle at a minimum rate annually until a new vehicle was operational.  We talked about the role of the congress and White House as compared to the role of the NASA Administrator.  Later, we talked about the role of public support and individuals petitioning congress on space policy.  Listen to his story about the Hubble repair mission.  I even asked if poorly written and fantasy driven letters to informed staffers helped or hurt the cause.  Listen for Mike’s response. In summary, Mike said his wish was that people would share is view that there are important things for society to do but that don’t look good on a balance sheet.  In the end, he said he was optimistic that his positive views on space would prevail and that when policy makers realized that China was going to put people on the Moon and what that would mean for the US, it would not be allowed to happen.
