We welcomed Michael Annis to the program to discuss his series of space & rocket history podcasts at http://spacerockethistory.com.  During the first segment, Mike told us about his background, being inspired by Apollo, and being a strong space enthusiasts going forward.  He strives for one podcast weekly.  Visit http://spacerockethistory.com/?page_id=344 for his timeline for existing podcasts with the newest on top.  Note that he started his series with his first podcast covering “Ancient Rocketry:  Standing on the Shoulders of Giants.”  As you will hear, he is still covering the Gemini program as his podcasts represent a detailed oral history in chronological order of events & missions that happened.  He does cover Soviet events plus events & rockets from other nations as applicable.  His sources are referenced in the podcasts but he does have a Source page, http://spacerockethistory.com/?page_id=27.  For this segment, we started at the beginning, talked about the history of rocketry and our space program.  One thing that I liked was his mention of the Flying Steam Powered Pigeon by Archtytas about 428 BC (see http://kotsanas.com/gb/exh.php?exhibit=2001001).  Listeners asked Mike questions about NewSpace, the Saturn V rocket, and for his favorite missions.  In this segment, Mike talked about the space interest of his students & their knowledge level of space history which was not good.

In the second segment, Mike mentioned Newton’s laws, especially his Third Law of Motion, especially action-reaction as he said rockets were based on this.  Our guest was asked about Mars as the focus and goal of human spaceflight and if he thought the US would likely lead a humans to Mars mission.  Another listener asked him about failures and he mentioned what he called a Flopnic, the Vanguard TV3 launch and the Soviet R7 rocket.  When asked about challenges to our space program, he cited budget problems.  We talked about the U.S. private sector which he supports.  Mike told us how to get his podcasts as they are available on iTunes and Stitcher.  Near the end of our program, Mike was asked about the Moon-Mars debate and his thoughts on the overall condition of our human spaceflight program.

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.

We welcomed back to the show Louise Riofrio to discuss her new book, “The Speed of Light.”  Remember that if you order this book through Amazon to use the OGLF Amazon portal so Amazon will make a contribution to TSS.  Instructions are on both The Space Show and our blog’s websites.  For more information, visit Riofrio’ s blog at http://riofriospacetime.blogsot.com. During the first segment of our 91 minute program, Louise told us about new developments and her work since her first Space Show appearance on Oct. 27, 2008.  She told her about her science work and related travels at JSC and her work with the moon rocks.  She also explained how her work with the moon rocks was important to human spaceflight, especially a return lunar mission and an asteroid mission.  She talked about why a lunar return mission was so important for science & why it was better to have astronauts on the mission rather than only robotic.  Out of this discussion came another SLS discussion as Louise pointed out the need for heavy lift for a lunar or any BLEO mission.  I explored her thoughts and opinions on SLS, asking her about the perspectives provided by those not supporting SLS.  In my opinion, Louise put forth excellent arguments in support of SLS during the show.  I even suggested she become the spokesperson for SLS and lunar return missions given how well she articulated and explained the need for SLS.  Louise also spoke about the distance from Earth to the Moon and the lunar orbit, referencing the LLRE (The Lunar Laser Ranging Experiment) from the Apollo era.  She used information from this device in comparison with three other measuring methods to support her theory that the speed of light is slowing down.  Listen to her explanation behind her theory assumptions.  Louise then mentioned the very accurate atomic clock soon to go up to the ISS, ACES (see http://www.esa.int/Our_Activities/Human_Spaceflight/Human_Spaceflight_Research/Atomic_Clock_Ensemble_in_Space_ACES).  She said this would be very helpful in detecting and clarifying the change in the speed of light.  John from Ft. Worth called with several questions and comments about the speed of light.   Next, Paul asked a series of email questions about time travel.

In the second segment, we started off discussing time travel and speed of light changes for a multi-generational human mission.  Louise introduced us to time dilation.  John in Montana asked about GPS timing & the change in the speed of light.   Christine emailed a question about an RTM mission and asked what might change if the speed of light is slowing down.  Next, we talked about Planck units and the equation GM=TC^3 which is the same as M=R=t.  Peer review was discussed as were the challenges of getting new theories introduced into the literature.  As you will hear, old ideas do not go lightly into the dark, so to speak.  Louise then talked about having discovered a lunar orbit anomaly and referenced her paper, “Calculating a Lunar Orbit Anomaly” which you can download at http://www.lpi.usra.edu/meetings/lpsc2013/pdf/2436.pdf.  As the program neared its end, I asked our guest about her idea that there might be a mini black hole in our sun.  Louise told us about her theory & talked in general about mini black holes.  Our last subject dealt with her interest in positive pressure suits for IVA purposes.

If you have comments/questions, please post them on TSS blog. You can reach Louise through her blog or me.

We welcomed back Rand Simberg and Bill Simon, co-authors of Evoloterra which commemorated when we first left planet Earth and landed on another planet.  To follow along with us with the ceremony, visit http://www.evoloterra.com.  During the first segment of our 1 hour 51 minute program, Rand and Bill explained the significance of the July 20, 1969 date and their Evoloterra ceremony.  Rand also said that our earlier Moon program was a dead end path and that we will not be going back to the Moon the way we did Apollo. This comment provided an overriding theme throughout the program as Rand explained why large unaffordable rockets were not the way to do things when we could do smaller rockets, use fuel depots, and make space more affordable.  Bill explained the July 20th significance saying it was the turning point when humans were no longer bound by Earth.  Rand and Bill read the Evoloterra introduction which is a passage from an Arthur C. Clarke novel.  Bill also pointed out the significance of going to the Moon in peace and that the U.S. made no effort to nationalize or conquer the Moon.  Rand and Bill then took us back to the affordable and scalable space program needs and said that our current program was neither affordable or scalable.  I asked them both for lessons learned and I bet you won’t be surprised by the answer I got.  Rand cited SpaceX many times during the program, especially as a model for affordable space and for having a vision.  In response to listener questions, Rand said cost was a nonsense issue.  Don’t miss why he said this multiple times during our program.  Near the end of the segment, our guests talked about the myth of Apollo, space leadership issues, and Rand’s frequent statement that nobody cares about space which he then demonstrates by the space policies now in play.

In Part 2, Rand talked about his USA Today article, “Apollo Program A Flameout At 40″ (http://www.usatoday.com/story/opinion/2014/07/18/apollo-nasa-anniversary-moon-column/12734813).  Rand also mentioned Part 3 of the Brian Berger series on space in the Houston Chronicle (www.houstonchronicle.com/nasa/adrift/3).  During this segment, we talked more about the Evoloterra ceremony, how it was modeled on the Seder, & the importance of ritual in helping people remember historical and important events.  Later, space property rights came up for discussion, then our guests each gave us closing comments.  Rand’s summary was that there was a better way than the big rocket.  Bill Said Apollo 11 was a water shed event.

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

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

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

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 to Hotel Mars Dr. Haym Benaroya from Rutgers University. Dr. Benaroya discussed the NASA LADEE mission, lunar dust issues, the lunar surface, the importance our astronauts returning to the Moon and the Lunar Dust Experiment which so far has proven to be inconclusive regarding the questions it was to solve. Dr. Benaroya went over the toxic and corrosive nature of lunar dust to both humans and equipment, had similar things to say about Martian dust, and talked about how important it is for us to go back to the Moon. He also made the point that we should have a permanent settlement on the Moon and not just use it as a way station stepping stone to Mars, abandoning it again once we are on Mars. The three of us discussed the LADEE project in detail (as much detail as we could in this short segment). We also talked about its end which should come April 21 by crashing into the far side of the Moon.

We welcomed back Dr. Jeff Bell & was at his best for blunt talk, specifically the need for a winning rational for human spaceflight (HSF).  For those of you new to Dr. Bell, hold on tight for a ride that will likely be upsetting.  During the first segment of our 1 hour 58 minute program, Dr. Bell started with saying he was pessimistic over the future of human spaceflight.  In fact, this was an overriding theme throughout the full discussion.  He said it was more than just not properly telling the story either by NASA or space advocates.  He said there was no winning rational for the need or the urgency of HSF.  While he was pessimistic on HSF, he was just the opposite on science, robotic, & unmanned missions which he said were doing well & in a class of their own.  He also talked about the success of satellites & that part of the commercial industry.  Listeners challenged him during the show.  He got several emails regarding space settlement which Jeff addressed in terms of his perspective on HSF.  He also nixed the idea of leaving Earth as a safety valve for when Earth might be destroyed by an incoming NEO.  This led Jeff to talk about planetary defense.  Tony called with an idea to keep a Martian settlement from freezing at night, a point Jeff talked about re Mars settlements.  A listener asked about radiation & magnetic fields.  Jeff said the atmosphere was more of a screen for Earth, again in a discussion about lunar & Martian settlements.  Jeff talked about Orion & SLS, various ideas for Mars missions & the NASA asteroid mission.  I asked Jeff what he was positive about & he replied the Russian space program & SpaceX with Elon.  He then spoke about some of the Russian programs he follows.  He was asked about space tourism & suborbital flights, then he spoke about SpaceShip2 problems, hybrid engine issues, Richard Branson & more.

In the second segment, he had more to say re SpaceShip2 & Branson.  Next, he was asked about space debris cleanup ideas being skeptical of them.  He was also skeptical of propellant depots.  He spoke about small boosters costing much more than using one large booster.  Pooley called in to support everything Jeff was talking about.  Dr. Bell was asked about Dream Chaser.  In general, Jeff was very critical of lifting bodies & their CG problems.  Listeners asked for his assessment of Inspiration Mars & Mars One which was not positive.  In his closing comments, he said HSF was probably mature & needed radical new technologies to make it cheaper & feasible.  I told him he should come back on the show, invite only callers & emails suggesting radically new & different technologies & he could assess the ideas.  Dr. Bell agreed to do that so watch the newsletter for this upcoming program.

We welcomed Gwynne Shotwell, President & Chief Operating Officer of SpaceX back to the show for an hour discussion & Q&A from the listeners.  During the first hour segment of this 72 minute program, Ms. Shotwell started out with me asking questions prior to opening the program to the listeners.  I inquired about using Brownsville, TX as a spaceport, SpaceX qualification requirements & timelines to fly sensitive USAF costly spy satellites to orbit, reusability, the possible use of Falcon & Dragon for a lunar mission, and fast tracking Dragon for HSF given the problem with Russia, the Crimea, and the Ukraine.  Gwynne told us about New Dragon and modifications to it and theCRS-3 Dragon contamination concerns for the upcoming launch on March 30.  About 20 minutes into the discussion, I opened it up for listener emails and phone calls.  I did have some audio issues with the toll free line so I apologize in advance for them but all the callers were clear and understandable as the problems concerned the toll free line ringing.  Listner questions addressed launch pad modifications for larger rockets, the SpaceX Raptor, reusability, possible payload penalties with reusability, propulsive landings, and reusable launch vehicle trajectories.  One listener asked our guest about possible markets for the bigger Falcon heavy lift launcher, Falcon XX.  We learned that this size rocket was for human transportation to Mars.  Gwynne fielded several questions about Falcon and Dragon on lunar missions.  While not opposed to lunar missions, SpaceX does not want to be distracted from their primary objective which is Mars.  Another listener asked about pricing and secondary payloads, the launch abort system, then I asked about SpaceX near term challenges and longer out challenges to 10-11 years from now.  Our guest was asked about berthing and when SpaceX would dock with the ISS.  Later in the segment there was a question about competition in the launcher industry, if SLS was viewed as competition, using a Falcon for a Europa or Titan mission, & the difference between Air Force requirements and special NASA requirements.  As the segment was drawing to a close, a high school student asked about internships at SpaceX.  Gwynne also talked about how valuable & important their relationship with NASA has been and how NASA has been a large part of their success.

In the very short second segment, I went over the upcoming Space Show schedule and let the audience know several dates when there would be no programming due to Easter & my personal schedule.
