We welcomed Charlie Precourt back to the show to discuss SLS-Orion progress and milestones, human spaceflight, technology advancement, & much more. During our one segment 63 minute discussion, I first asked out guest about the Orbital ATK merger and business under the combined companies. We soon shifted to the SLS-Orion discussion which included information on the 5 segment solid rocket booster (SRB), tonnage to escape which our guest explained, possible missions, and opportunities that will become available as a result of having this heavy lift rocket available for missions that need the lift & high energy capacity of SLS. We talked about shorter travel times, larger payload mass & volume, plus higher energy transfer orbits using SLS as compared to an EELV. Charlies was asked about SRB safety for human spaceflight. Don’t miss his comments on this issue. He talked at length about the benefits of marrying the SRB for lift out of a gravity well to liquids for propulsion once in space. Our guest provided statistics on SRB launches and uses to support what he was telling us. Charlie also talked about his Space Shuttle flight experience and the Shuttle’s SME, especially when there was an SME problem on one of his shuttle flights. We talked about going BLEO and he introduced us to the concept of One Space. As a result of listener questions, our guest talked about SLS costs, its design for multiple destinations and missions, and the launch “sweet spot” that it would fill. BJohn asked if there were uses for an SRB or solid rocket motor in space. Charlie said for liftoff from a gravity well, yes, but otherwise the SPI for a solid was likely too low for in-space propulsion. I asked our guest about Orbital ATK meeting the SLS -Orion milestones and upcoming flight testing. Jeff from Tucson called in about the use of modern technology including light weight epoxy material for SRBs & other spaceflight hardware. Near the end of the program, I asked Charlie about the justification for HSF to see what he had to say about it. Don’t miss his reply. We then talked about technology challenges in going to Mars, choices that were made to do the shuttle and ISS over deep space missions, and destinations that were still Earth dependent as compared to those being Earth independent such as Mars. Jack emailed in a question based on a show earlier in the week where the guest said that for putting SPS infrastructure in space, SLS was too sophisticated. What was needed was big rockets that had a 2% failure rate as that rocket would be lots cheaper than an SLS. Charlie did not specifically comment on SPS infrastructure but did take issue with the notion that it would be fine to have a rocket with a high failure rate to make it cheaper than something like SLS. Listen to how he explained this. Tell us what you think on TSS blog. As the show was about to end, a listener ask Charlie, based on his F15, Air Force, and test pilot experience, what he thought of the new F35 Joint Strike Fighter and the shortcomings of the new fighter that are reported in the press. Charlie had interesting comments about this so don’t miss them.

We welcomed back Dr. Jim Woodward to the program to discuss the Mach Effect, Mach thrusters and drive, and breakthrough propulsion. During our discussion, Dr. Woodward mentioned his book, “Making Starships and Stargates which you can order at http://ssi.org/exotic-propulsion-initiative as this allows SSI to get a royalty payment on the sale of the book. If you buy the book through Amazon using TSS/OGLF portal, The Space Show gets a percentage of the sales price of the book. In addition, the Charles Platt article, “Strange thrust: the unproven science that could propel our children into space” can be found here: http://boingboing.net/2014/11/24/the-quest-for-a-reactionless-s.html. Finally, Dr. Woodward mentioned the paper written by Dr. Heidi Fearn, “New Theoretical Results for the Mach Effect Thruster.” You can download this paper at www.researchgate.net/publication/280134421_New_Theoretical_Results_for_the_Mach_Effect_Thruster. Note that in the final minutes of our program, Dr. Woodward spoke very softly and we were unable to get some of what he said as part of his final comments. While the 1 hour 56 minute program was divided into two segments, this summary will be in one segment only and short as the papers above tell the story. I urge you to read them and become familiar with Dr. Woodward’s work either before or after listening to this discussion which was at times very technical and heavy in the theoretical physics fields for gravitational forces, electromagnetic forces and more as he described the Mach Effect. In addition to the physics, since Dr. Woodward’s work is dependent on funding so he spent a good amount of time in both segments answering questions and telling us what it was like trying to get funding, approved proposals, etc. for cutting edge work or even work considered to be out of the box or on the fringe. His realistic assessment of the challenges posed by his and similar work goes to the point of why we don’t see more out of the box science & advanced projects being financed. In addition to the physics and funding discussions, we talked timelines for his having commercial uses for small Mach thrusters which would start off servicing satellites. This discussion covered both segments.

Please post your comments/questions on TSS blog above. You can contact Dr. Woodward through me at drspace@thespaceshow.com or his Cal State Fullerton website.

We welcomed Dr. Eligar Sadeh back to the show to discuss his recent Astropolitics published article, “Report: Public Private Partnerships and the Development of Space Launch Systems in the United States.”  You can find this report on The Space Show blog for this particular program. During the first segment of our 92 minute program, Dr. Sadeh introduced us to the topic and the Report subjects which you can read on TSS blog.  He addressed the traditional aerospace contracting model, the problem with cost overruns which hurt the traditional model and some of the issues with fixed price contracts, especially with technology and commercial opportunities.  We talked about risk reward and he cited SpaceX and Orbital Sciences as examples of the success of the private public partnership type of arrangement.  In addition, Eligar suggested that such partnerships were supportive of developing programs such as space transportation services.  Other topics in the first segment included SLS, National Security Space, big science programs, planetary missions, and others that still use the traditional model.  Our guest introduced us to the Better Buying Power approach which he referenced several times during the show.  Tim called from Huntsville to talk about risk, profits, and cubesats.  Eligar then went into some detail about the competitive launch environment, specifically for national security payloads and how that is now changing and opening up.  Jake emailed us to inquire if Congress was fully on board with these new public private partnerships.  Jennifer wanted to know how international participation might change the public private partnership relationship.  Next, I asked Eligar to explain the Acquisition Death Spiral which was in Fig. 4 of his Report paper.

In the second segment, John from Ft. Worth was our first caller & he wanted to address the risk in a fixed price contract.  John and Eligar had an interesting discussion on controlling costs and risks so don’t miss it.  Later, I asked Eligar to explain the New Entrants Certification Guide (NECG) which was issued in 2011.  This document provides the guidelines for the competitive launch environment for national security and other launch competitors.  Our next caller, Doug, wanted to talk about public private partnerships beyond LEO, specifically the Moon.  Eligar talked with Doug about leveraging assets for the private sector, citing the ISS and a few of the commercial users as examples.  Both Doug and Eligar had a very interesting and comprehensive discussion on this topic which considered cislunar transportation, a lunar hab, possible commercial incentives to drive commercial involvement, and more.  Policy and leadership were part of this discussion as was the fact that there currently is no lunar hab, Lunar Cots, or cislunar transportation policy nor is one being considered.  After the discussion with Eligar ended, we used the balance of our time to discuss the likelihood of a fast moving lunar based Chinese space program influencing the US to fast track developing a lunar hab and cislunar transportation.  Prior to our discussion ending, I asked Eligar how listeners could get copies of the journal Astropolitics as Eligar is the editor for it.

Please post your comments/questions on TSS blog above.  You can each Dr. Sadeh through me or his email address on his Report on the blog.

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.

Welcome to this two hour webinar regarding the choices and considerations that can be made in designing and configuring launch systems.  TO VIEW THE WEBINAR VERSION OFTHIS PROGRAM, GO TO https://vimeo.com/126223310.   Note that on the blog for this program are two Power Point presentations for your use.  Dr. Jurist referred to both of them during the webinar, especially the presentation titled “Choices: Some Considerations in Configuring Launch Systems.”  I urge you to follow along with them during the webinar.  During the first segment, Dr. Jurist explained the target market for the webinar and his two presentations.  He then talked about how hard it was to go to Mars and do other missions.  Then he got to the point by saying in designing or configuring the launch system for a mission, you started with the payload requirements which then provide additional constraints once the payload has been defined.  He also talked about the application of the basic rocket equation and explained the importance of exhaust velocity, the Delta-v, and the mass ratio.  Listeners started asking questions so two stage compared to single stage was discussed.  John pointed to the Choices presentation, slide 8.  He talked about propellant and pressures, both in a pressure fed system and with a turbo pump system.  Another listener asked about solids versus liquids, then Marshall called to talk about rocket g forces.  Dr. Jurist talked about designing the rocket envelope environment to the payload specifications.  He then brought in and discussed the vibration envelope.  Helen asked how things would be different with a human payload rather than a satellite or cargo.  Reliability was a big concern.  Near the end of the segment, Dr. Jurist talked about payload mass in Leo and BLEO.  Doug inquired about the gravity loss during the launch, then the segment ended talking about heavy lift, solids and proportional cost factors for SRBs.

 

In the second segment,  Penny asked how the variable that had been discussed would change were one launch from the Moon or Mars.  Adrian emailed in about the NERVA rocket and nuclear propulsion.  Dr. Jurist used the German V2 as an example of launching from the Moon.  Specific impulse and exhaust velocity came up again, then the focus turned to rocket motor cooling systems.  Questions continued coming in asking about 3D printing of rocket motor parts to lower the cost and the use of hybrid rocket fuels with their advantages and disadvantages.  Regulatory issues came up in this segment as did political issues, plus our guest got a question about amateur rocketry.  A listener asked about environmental concerns over rocket fuel . Dr. Jurist directed the audience to the Choice presentation, slide 22, and talked about ways to possibly shed some weight such as dumping the payload shroud.  Near the end, John got questions about the Falcon Heavy, Doug called in with questions about lunar lander economics and more.  In closing, Dr. Jurist said “the fundamental theme of the presentation was the many variables that come into play in designing or configuring a space launch system, how the many variables are inter-related, and how every decision in the process constrains or narrows the remaining options.”

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.

Welcome to our Open Lines discussion.  In the first segment of this 2 hour 2 minute program, I put forth some suggested topics and once again, I explained phone line issues for listeners regarding land lines, VoIP, compression, cordless phones, cell phones, digital phones, and even fiber lines.  Phone line issues remain the number one problem faced by The Space Show in delivering quality audio so once again I went over the requirements and the restraints based on our equipment and broadcasting equipment in general.  Several listeners did comment on the phone line issues via email.  John from Florida was the first caller and he talked about Ernst Stuhlinger and his work plus he requested Dr. Jeff Hoffman of MIT return as a guest to the show.  During our conversation, I mentioned ULA CEO Tory Bruno recent & his lecture at Stanford on the pros and cons of rocket reusability (www.youtube.com/watch?v=9DMb2yHh5CA).  Marshall was the next caller who talked about cell phones and the DSP computer in the phone. He also talked about SOHO and replacing old satellites with new ones. We talked about the cost of doing that and Marshall said he would gladly pay 5% more in taxes if he was guaranteed the money would be used for satellite replacement. I asked other callers if they would do that but nobody bothered to respond.  Marshall said we needed a satellite replacement program so jokingly, I suggested a Cash For Old Clunker Satellites modeled after the Cash for Clunkers car program several years ago.  Michael Listner called to talk about recent news articles suggesting the FAA was going to regulate lunar business.  He clarified this for us.  Emmet sent us a note suggesting Doug had a video on the net which had gone viral thus making Doug an internet star (www.youtube.com/watch?v=Rzy63276GEg).

In the second segment, Doug called the show & explained the video as a product of http://www.moonandback.com.  Doug talked about the planned SpaceX launch later in the day, the recovery of the first stage and the Falcon Heavy as part of his overall heavy lift discussion.  He also raised some questions about the Dawn Mission and its potential findings regarding Ceres.  Turbo pumps came up as did other issues with liquid rocket motors such as which fuel to use given my promoting the late April webinar addressing these and other rocket issues.  Ken from Dallas called to talk about Moon Day set for July 18, STEM, and he also mentioned Asteroid Day set for June 30.  As Ken is a sci fi movie authority, we talked some movies and TV shows.  John from Ft. Worth called and mentioned a movie and the satellite being launched by SpaceX nicknamed the Al Gore Satellite for Climate Change.  John briefly mentioned The Telegraph article showing how temperature data had been tampered with and calling it the biggest scandal ever (www.telegraph.co.uk/news/earth/environment/globalwarming/11395516/The-fiddling-with-temperature-data-is-the-biggest-science-scandal-ever.html).  John put forth some growth and population statistics as part of his argument against global warming.  Other subjects mentioned during this open lines by listener emails included why there was no live streaming of the first stage recovery attempt for the Falcon 9, why drones were not suitable for live streaming as they were with the Orion flight, plus many listeners emailed in about Cash for Clunkers & old satellites and the projects and work of Ernst Stuhlinger.

 We welcomed Dr. Andrew Rader to the show to discuss his aerospace engineering lectures and other material on his website, http://www.andrew-rader.com as well as his YouTube channel.  You can access all his material, his YouTube channel and his book through his website.  During our one segment one hour discussion, Andrew talked about his Mars cooking video regarding his eating bugs.  We had quite the discussion about this.  Crickets anyone?  Next, we talked about going to Mars and he introduced us to his YouTube channel which has 74 videos and more on it.  His aerospace engineering class lectures are there too and very popular with students, especially those wanting to see if aerospace engineering might be the path for their studies.   Joe asked our first email question about the necessity for a flyby or human orbital mission of Mars prior to humans landing on Mars.  We then discussed Mars, why a one way mission, and the Moon vs. Mars.  Other topics included spacecraft and rockets in general, Apollo, robotic missions, and more about human spaceflight.  At one point I asked Andrew how he stated the purpose for our going into space.  Bethany asked Andrew to explain what was meant by the term ecliptic. In response, Andrew offered a short explanation using basic orbital mechanics.  We talked about several specific videos on his YouTube channel including the Sagan Darkness video, the Ambien Space Music videos and the Star Trek and Darth Vader videos.  I asked him what he liked best and he said it was systems engineering because he liked putting and seeing how everything works together.  Human factors came up and he made an interesting statement to the effect that if we require 21st century medical care on our space missions, the technology itself may be an impediment to the mission.  We talked about the multi-systems failure risk being the biggest risk in his opinion and the steps taken to mitigate this risk.  I also asked about crew failure risks including medical and psychological issues.  Andrew offered us interesting observations about crew risks and issues so don’t miss what he said.  As the show was drawing to a close, we talked about his introduction to spacecraft videos.

This program which originally aired on Dec. 31, 2012 as Tom Olson gave us his annual Space Show year in review analysis with a look forward to 2013 for space development. We started our 1 hour 36 minute discussion by remembering those in our space community that are no longer with us. We specifically mentioned three dear friends though we know that others have also left us. Our program was dedicated to Neil Armstrong, Jesco von Puttkamer, and Reda Anderson. We certainly miss our friends but space development marches on like everything else in life. A few of the early issues Tom brought up in the 2012 annual overview of space included the Falcon 9 launches and Dragon missions. He also talked about ISDC and birthing of Dragon during the keynote by NASA Administrator Charlie Bolden. While on the subject of SpaceX and its mission to the ISS, Paul sent in a question asking if SpaceX dropping out of the Stratolaunch project indicated that perhaps they had “bitten off more than they could chew.” Tom and I have no inside information about SpaceX and Stratolaunch but we both thought that Paul’s comment was reasonable as SpaceX is certainly busy enough with game changing projects & technology. Cubesats were discussed given their rise in popularity and importance in 2012. It seems as if their potential is more than on the rise! Cubesat growth also cuts across many diverse space industry segments and niche markets. Bev asked about the future of 3-D printing and its potential impact on future human spaceflight (HSF). 3-D printing is certainly experiencing space industry growth & there will soon be a small 3-D printer on the ISS. Heavy lift came up and much was said about the Falcon Heavy and SLS, both looking back over 2012 & forward to 2013.

 

In our second segment, I asked if fuel depots would evolve from the Power Point & rhetoric stage to something more tangible in 2013. We talked about depots as many of the projects announced in 2012 use depot technology to enable their plan. Tom talked about warp drive becoming more possible due to the 2012 work of Dr. Sonny White. Dr. White will be a guest on The Space Show Friday, January 4, 2013. Tom next brought up NASA budget issues & possible cuts. He talked about science mission cuts, the JWST, and on the HSF side, SLS eating up much of the budget with commercial crew still needing funding. I asked Tom how he thought space advocacy made out during 2012. Mixed was a one word summary of this discussion. Next, we talked about space settlement being made part of the U.S. space policy in 2013. Tom went over the pros & cons surrounding this effort. Doug called in about space settlement & I referred him to earlier programs with Steve Wolfe who authored the Space Settlement Act of 1988 which is part of public law. Tom said space settlement was SLS dependent & that makes the potential policy controversial to many space enthusiasts since many oppose SLS. Tom said 2012 was a good year for new commercial space grandiose missions such as Golden Spike, Planetary Resources, Mars One, a lunar base, Shackleton Energy, even EML2 missions. He kept asking the questions regarding objectives, who pays, the reasons for the missions, and more. He said most of these missions rely on some form of large launcher, either the Falcon Heavy SLS. Tom talked about ITAR reform that has been signed by both houses of Congress & is applicable to the U.S. satellite industry. Human rating of the Atlas came up for a 2012 progress report, then Dave in San Antonio inquired about cyber warfare & the space industry in 2012 & the future. 2012 marked the year the space shuttles went on display in museums & Tom talked about the Russian space program investments for modernization over the coming decade. He also talked about other national space programs. Near the end of our program, we brought up the Spaceport America liability issue & the risks facing the New Mexico spaceport. Tom updated us for 2013 on the NewSpace Business Plan Competition & his work with the Exodus Group for space business consulting.

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.
