Welcome to our Open Lines show. In the first segment of the program, I suggested a few topics and then talked about our Website Modernization Program and the new fully searchable database to deliver archival quality archives. I went over a few more of the benefits for everyone with the new site and urged listeners to not only participate in our campaign but to help spread the word through their own networks, Facebook, etc. Our support site is at www.supportthespaceshow.com and our campaign site address is www.indiegogo.com/projects/oglf-and-the-space-show- modernization-campaign/x/11584678#/story. By the way, the new site will use hyperlinks!!! John Hunt was our first caller to discuss the book “The Martian,” plus his take on Dr. Woodward’s mach thruster work given he had just finished reading Dr. Woodward’s book. John had much to say about “The Martian,” especially from a technical perspective. It is an interesting and fun discussion. His comments on mach thrusters were somewhat skeptical but he was still thinking about it and Dr. Woodward’s work as detailed in his book. He will give us a report when he has reached his “final” decision. John’s feedback on this is interesting given his knowledge of physics. He was asked what it might mean if Dr. Woodward’s work was to be verified and commercialized. He said it would be revolutionary and would open up the solar system to space travel. Near the end of the first segment, John also mentioned EM drive, the challenges for out of box theories and work when going up against science orthodoxy & related issues.

In the second segment, we heard from Jon in NJ about new uses for space shuttle main engines, SLS, and reusability which he said did not appear to be something NASA was interested in at this time given their engine use plans. Another discussion topic that came up was comparing a Return on Investment (ROI) to a Return on Exploration (ROE). I mentioned that government projects are not typically discussed in terms of an ROI and that it was very difficult to calculate a ROE because for government, that includes many things, variables, and ways of calculating outcomes. I mentioned an earlier Mars Society paper I did years ago on comparing Apollo to the school breakfast program and Hoover Dam. I addressed calculating benefits, outcomes and an economic return for each of those three projects. BJohn emailed in a comment about returns going back centuries for Mars exploration, then we got into discussing the technical knowledge and awareness of society in general. I mentioned the upcoming program with Dr. Lewis Dartnell on his book “How To Rebuild Civilization In The Aftermath Of A Cataclysm.” We talked about starting up space settlements from scratch, what it might take to be independent of Earth & how similar it might be to rebuilding a civilization after a disaster. This topic consumed the balance of the show with listener emails and calls.

We welcomed back Charles Miller to discuss in detail the recently released NASA Study, “Evolvable Lunar Architecture that Leverages Commercial Space Capabilities and Public Private Partnerships.” You can read and download the report, “Evolvable Lunar Architecture that Leverages Commercial Space Capabilities and Public Private Partnerships” at http://titan04.ksc.nasa.gov/shuttle/nexgen/Nexgen_Downloads/NexGen_ELA_Report_FINAL.pdf. During the first segment of our 1 hour 39 minute show, Charles introduced us to the study, the background as to why the need for the study, plus he said that to find an affordable way to move humans out into the cosmos there needed to be an affordable way to do it. He briefly summarized the history of efforts to return to the Moon since Apollo, then explained why this new approach, modeled after the COTS program, was so much better. Through the creative use of the public-private partnership program, returning to the Moon can be easier and more affordable. Charles was asked lots of listener questions including questions that addressed the TRL level of both NASA and the private companies to go to the moon, public and private risk taking, commercial competition, and the strategic use of fuel depots to further reduce mission costs. He explained their program step by step through three phases. Listener Dan asked a series of question about robots being serviced on the Moon, asking if the humans would be better placed elsewhere to control the lunar robots using low latency telepresence rather than humans on the Moon. Don’t miss how Charles responded to this series of questions that Dan emailed us. BJohn was also active with questions ranging from asking about the Lunar Mission One program to questions about the costs and assumptions used in the NASA study, even the use of GEO. Other listeners wanted to know about lunar settlement as part of this study, lunar habitats, and using L2 rather than the lunar surface. Listeners also asked Charles about lunar microgravity issues and radiation. Charles had the most to say about radiation issues. Later in the segment he said the plan called for a migration of the initial program to something like an international lunar authority modeled after CERN and modern airport authorities. Dan asked another question about getting astronauts off the moon in an emergency wondering if there would be greater safety margins if humans were not required on the lunar surface. Charles indicated that there would be a lunar escape system on the Moon. When questioned about the economics, it was clear that the study had in mind to facilitate human expansion BLEO so options not expanding the human presence BLEO were not options considered for the study. Todd asked if SLS was considered in their analysis. The answer was no as they only looked at commercial launch options, not government launchers. More questions came up about how the project would be financed relative to the NASA budget. Don’t miss this analysis and explanation.

In the second segment, BJohn asked about the Falcon Heavy regarding fuel depots. Charles said it was a LEO only launcher so not considered in their study. More listener questions came in regarding depots. BJohn also asked about the use of GEO. Charles explained why this was not an option. Eric and Charles had quite the email exchange about needing humans on the lunar surface. Charles said they were primarily there to repair and maintain the robots and equipment. Eric kept asking about using robots for the repair and maintenance but Charles said that technology was not available at this time. Their give and take was a good discussion of the subject. As Charles pointed out, since a commercial company would be on the moon with the robots, they would have every reason to advance their technology to be more cost effective so moving toward robotic servicing of the lunar surface robots would be something a company would be motivated to do to save on operating costs. However, that technology was not available today. Listener Josh wanted to know about other potential lunar businesses including lunar tourism. Charles was asked about lunar cubesats, then near the end he was asked about property rights and lunar resource exploitation. As the program was about to end, we talked about the political process and progress the study needed to make as it worked its way through the policy makers, Congress, and others. Please post your comments/questions on TSS blog above.

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 Michael Mackowski to The Space Show to discuss his book “Adventures in Space Advocacy,” space advocacy in history through to the future, spacecraft model building and much more. During the first segment of our 90 minute program, Michael talked about growing up as a “child of Apollo” and being inspired by our early space program. He went on to get an EE degree and to work in the industry. He said it was an exacting time, especially when the Galileo Jupiter mission finally happened. He talked about the start of organizations such as L5, The Planetary Society, AIAA, and his own early ventures into space advocacy which are detailed in his book, available at Amazon at www.amazon.com/Adventures-Space-Advocacy-Personal-Activism/dp/1511564911/ref=tmm_pap_swatch_0?_encoding=UTF8&qid=1438189701&sr=8-1. He talked about moving, heading to Phoenix and engaging in space advocacy once again after a brief pause when he was in Washington, DC. This led us to a discussion about individual advocacy efforts as compared to group or organizational efforts. Michael was asked how he has sold human spaceflight to a general audience, his most receptive audience, and lobbying congress. Our guest spent some time discussing the challenges in advocating human spaceflight to the general public so don’t miss this discussion. Space tourism came up as a probable kick starter once the industry starts commercial operations. Michael thought that space tourism could provide a crucial boost for industry support even outside the space community.

 

In the second segment, we talked about Michael’s interest in spaceflight models. If you visit his website, www.space-city-mike.net, you can click on scale models on the right side menu bar (http://space-city-mike.net/modeling). Michael described the industry, licensing challenges, specialty model builders and more. He also talked about using models in the form of make and take kits when talking to young students about space. Model building through 3D printing was discussed, then I switched the topic to inquire about his success in outreach with adults and children. He said 5-7th grade was the best group to talk with as high school was probably too late. As for speaking to adult groups, he said it was usually about entertainment but that it seldom produced advocacy action on the part of the adults hearing the talk. I seconded that experience given my talks with adults on space this and that. Near the end, we talked trends, the increasing influence of social media, passion, and connecting pace to our future.

We welcomed Dr. Robert Pappalardo to the show to discuss Europa and the upcoming Europa Mission by JPL which is now in the development phase. During the first segment of our 1 hour 27 minute program, Dr. Pappalardo talked about the origins of the NASA JPL Europa mission now in the development phase. He briefly described the experiments & instruments planned for the mission, then answered questions about the mission such as will the mission search for life. In response to this question, he said it would search for simple life through an indirect means which he described more fully in the second segment of the show. Our guest talked about having learned lots from the earlier Galileo spacecraft, especially about the Europa magnetic field and the likelihood of the oceans consisting of saltwater. Dr. Pappalardo also talked about the structure of Europa with the icy surface, oceans under the ice ad then a rocky base under the oceans. Dr. Pappalardo brought up the tidal heating of Europa and spoke to that quite a bit during the show. He talked about chemical energy and nutrients which may support simple life in the Europa oceans. Listener Joe asked how Europa could be in a habitable zone, even for simple life, given its cold temperatures. Our guest said Europa was expanding the definition of habitable zone & that the tidal heating was crucial to the possibility of finding simple life molecules. Don’t miss his complete response to this question. We talked mission timeline which was from about 2022 to the mid-2020s. We also learned that the Europa launch window was every 13 months. Our guest was asked about transit time to Europa. He said it depended on the rocket. With SLS it would be less than 3 years. Another rocket would take at least 3.5 years or longer. We also discussed bandwidth issues for getting data, images, and video back to Earth. I asked about the possibility of using cubesats as part of the Europa mission, then Bob talked about the radiation challenge which he said was significant because Jupiter acts as a giant particle accelerator. Don’t miss this discussion, especially the part abbot how much ice would be needed for effective shielding. Also, the Europa satellite will come as close as 25KM to the surface of Europa.

In the second segment, Bob went into detail about the scientific instruments that will comprise the Europa mission. He took us through each one in detail so don’t miss it. The radar pushes the technology envelope. So does the mass spectrometer. Harry wanted to know if a plutonium RTG would be used for power and if they were anticipating Cassini like protests. Bob said that they would be using solar power. Again, don’t miss the discussion. Cindy asked Bob about the length of the Europa day and year, another listener asked about Europa volcanoes and we learned that Europa has icy volcanoes. Amber wanted to know if the ice on Europa was the same as ice here on Earth. A UK listener wanted to know why Europa was not sucked into Jupiter by the planet’s huge gravity field. Don’t miss Bob’s explanation of this. Toward the end of the segment, he talked about the significance and importance of the search for simple life molecules/organics. Final questions concerned specific Europa classes at the college level & more on the European JUICE Mission and its plans for Europa. We agreed to stay in touch with one another regarding Europa and the upcoming mission so Dr. Pappalardo will be returning to The Space Show.

Please post your comments/questions on TSS blog above. You can reach Dr. Pappalardo through me or JPL.

We welcomed Jim Muncy back to the program to discuss current space policy and budget issues before the U.S. Congress, company updates, and much more.  During the first segment of our 1 hour 50 minute discussion, Jim provided us with the groundwork for most of our discussion by going back to the Commercial Space Launch Act of 1984, then the update to it known as the Commercial Space Launch Amendments Act of 2004.  He talked about both the House and Senate versions of the NASA and space budget bills and some of the differences between the two bills.  One difference which he explained in detail early in the second segment had to do with the learning period which is important for the developing industry.  Another difference between the two revolved around extending the ISS commitment to 2024 plus issues relating to BLEO space.  When asked if he thought the final bill would be signed or vetoed by the president, he said it was nonpartisan and he did not see problems getting it signed into law.  Listeners asked about funding SLS.  Much was said about SLS in both segments but one listener asked Jim why so many supported SLS given its shortcomings.  Jim explained the mindset of many SLS supporters in congress. As you will hear, SLS is hardly a black or white issue.  This discussion led to a related discussion on developing a new rocket engine, the issues involved, the competitors, methane versus other fuel, and more.  In particular, he used Alabama Congressman Mike Rogers as an example supporting is analysis of the situation.  Jim was asked about the impact of the Falcon 9 failure which led him to address the need for multiple launchers and competition.  Later, Alex asked him about his areas of concern regarding the pending budget legislation.  He talked about sequestration, spending caps, delays, and the problem with operating on a CR which is likely.  This is a lengthy but important discussion so don’t miss it.  Before the segment ended, Jim was asked about the lunar lander.  Jim then talked about the Flexible Path, Google Lunar XPrize, cislunar space development and Mars.  Jim advocated the need for public private partnerships, then he was asked about international partnerships.

 

In the second segment, we started with an email question from Doug inquiring about the Augustine Commission presenting an option for returning to the Moon with landers developed in a public-private program context.  After Jim’s response, I asked him to refer back to a comment he made in the first segment and to explain what was meant by the learning period.  This was an important discussion so don’t miss it.  As part of his response, he also provided a short overview of the suborbital industry and participants plus the orbital industry.  A good portion of this segment focused on the importance of the learning period.  Our last question of the evening was from Helen.  She asked Jim if it would be beneficial to ask political candidates in the 2016 races space related questions assuming they know nothing about space.  Jim supported the idea but he told us all to make the question broader than just what interests us in the space industry. He gave several examples of this.  What he said made sense to me so I urge all of you who get a chance to question a 2016 candidate, ask your space question the way Jim suggested.

We welcomed Dr. Clark Lindsey back to the program for a wide ranging discussion on space industry news and issues. During the first segment of our 1 hour 47 minute program, Clark started out by talking about the changes over the years in the small satellite industry. He referenced several companies making news such as One World, Spire, Planet Labs, Skybox, Rocket Lab, Firefly, plus others. This brought him to an interesting cubesat discussion. Next up was the Falcon 9 launch failure from a few days ago. He did not have any new information and we are all still waiting for the cause of the mishap to be stated. He did clarify some of the confusion around the Air Force having sent a destruct signal to the Falcon 9. He said such a signal was sent but about 90 seconds after the event. We then talked about other rocket launch failures in the early days of the Arianne, Atlas & Delta history. Clark was asked about policy issues surrounding the RD-180 engine buy, Senator McCain, commercial crew, and congressional leanings at this point in time. Listeners asked him if he thought SpaceX was seriously hurt by the Falcon 9 accident. He said he thought the company was definitely wounded but it was too early to determine how badly the wound might be. He mentioned the Google billion dollar investment in SpaceX, their commercial manifest and more. Joe in Dallas wanted to know how he thought the Falcon Heavy schedule might be altered as a result of the launch failure. Clark talked about other work being carried out by SpaceX plus he offered some ideas on how testing of any new Falcon 9 systems might be integrated into testing other SpaceX projects including the Falcon Heavy. Jack in Boston wanted to know if Clark had any information on Virgin Galactic. Clark talked about XCOR in his answer and said the companies would likely be adopting a very slow go time table to assure no further mishaps.

In the second segment, we started discussing Clark’s slide presentation on the satellite industry per his talk at Space Access 2015. You can find these slides on The Space Show blog post for this program as I uploaded them to the blog with Clark’s permission. As you will hear later in this segment, we got sidetracked by listener questions and calls so Clark did not get to finish going through the slide presentation so I urge you to view the slides on your own as they certainly clarify the commercial markets and more for many of the satellite markets and uses. Earlier in the segment, Clark did talk about the GEO communication market, also the small satellite market for both LEO and MEO. He was optimistic that commercial companies will start to emerge to address the launch market issues for the small satellites. Clark did talk about the market for these satellites for tracking maritime shipping. He has a special slide illustrating this but from what Clark said, it sounds like a potentially very lucrative market to exploit. Clark fielded some questions about the legal and regulator regime for commercial space and said that not only was the technology pushing the frontiers of development, so were the space law and regulatory issues pushing the frontier for moving the industry forward. He used space debris removal as an example. Tim from Brooklyn sent in a note asking about space tugs and Falcon Heavy which was followed by a good discussion on SLS, space tugs, fuel depots, and one’s space vision for the future as SLS John called in to talk SLS and more with Clark. Tim wanted to know just what we could do today and over the next 5 years with a space tug and the Falcon Heavy. Don’t miss what Clark had to say in response to this question. As we neared the end of the program, Clark provided a sort of short rocket industry overview for us, he talked deep space rocketry, & cost effective SpaceX manufacturing processes. He quickly summarized several of his slides that we did not have time to discuss, then we both offered summary statements about the positive direction commercial space has been going in recent years, despite setbacks, with both of us believing the growth and progress will continue.

We welcomed Bob Zimmerman back to the program to discuss a variety of commercial space, space news, and related topics.  During the first segment of our 1 hour 56 minute discussion, Bob started out with an historical overview of the progress made in developing the commercial space industry, a U.S. cargo capability to the ISS, and eventually the U.S. capability of carrying astronauts back to the ISS.  He started his timeline in 2004, specifically addressing the time since President Obama came to office.  For almost the entire first segment, Bob noted milestones, progress, company developments, the beginning of competition and much more. Later in the segment, he mentioned what he said was the lack of progress in the suborbital industry during the time period he had been talking about and suggested that the suborbital companies may be missing parts of the market given their continued delays.  He talked about this in more detail during the second segment.  He also talked about human spaceflight (HSF), SLS, Falcon and SpaceX as a game changer, the efforts of Sierra-Nevada to continue on with Dream Chaser, & his opinion that it will likely be the private sector that manages HSF to the Moon and Mars rather than a public program.  We talked about public opinion and space, then Marshall called to ask questions about China, their space program, plus a possible Chinese impact on our space policy.  Bob had much to say about the Chinese program, then he had about an equal amount to say about the Russian program. Sylvester emailed in to also ask about China, specifically if Bob thought we would soon be cooperating with one another in space.  Bob seized this opportunity to make it very clear as to why he disliked international partnerships, instead preferring competition. Before the segment ended, Beth asked Bob for his thoughts on the Moon-Mars debate.

 

In the second segment, Kristen started us off talking about LightSail.  Bob had much to say about the mission, The Planetary Society, how it was funded, and the fact that it was based around using cubesats.  He then spoke to the success of cubesats and how they are changing aspects of the industry. Bob jumped to Comet 67 P, the Rosetta mission and the Philae Lander.  He used this opportunity to provide an overview of planetary missions starting in 1957.  In talking about the success of planetary missions, he mentioned the Dawn mission to Ceres and Vesta plus many more.  I asked Bob about New Horizons and Pluto. Bob had much to say about Pluto, its moons, & specifically the moon Charon.  Other topics that came up as we neared the close of the show included the Europa mission and an effort to use crowd funding to make a porno film in space. This prompted Bob to say a few words about sex in space, plus he thought the porno film was just a PR stunt.  Before the show ended, Tim in Huntsville asked for Bob to share his thoughts on the company Interorbital Systems.  Bob then turned to the suborbitals having some things to say about Virgin Galactic, Blue Origins, and XCOR. He spoke to the need for redundancy, mentioned possible Stratolaunch problems with Orbital ATK no longer working with them on the rocket, then suggested some things to watch for in the second half of this year and closed out with a summary of key points he made during this program.  Check out Bob’s blog, www.behindtheblack.com.

We welcomed back Dan Adamo to the show for this 2 hour 36 minute comprehensive discussion regarding HSF to Mars, the Second Mars Affordability and Sustainability Workshop report and much more.  During the first segment of our program, Dan started out by telling us the process used to engage him reviewing said report and writing his critique of it which is on The Space Show blog (https://thespaceshow.wordpress.com). Topics discussed in this segment included the use of Low Latency Telepresence (LLT) as compared to High Latency Telepresence (HLT), the absence of human factors and aerospace medical personnel in attendance and said issues missing from the workshop report.  Dan said the key missing information included radiation as well as microgravity concerns.  Dan then questioned the existence of a compelling rational for humans going to Mars.  This became a recurring discussion topic throughout today’s program.  Space settlement came up & so did a possible space race with China.  The subject of a rescue mission came up but there was a detailed rescue mission discussion near the end of the program in the second segment.  Dan was asked about the minimum crew size to operate an LLT program from Deimos or in orbit around Mars.  Several emails were sent in including one by Dr. Jurist addressing high acceleration upon return from Mars.  Dan then suggested the stepping stone approach, starting with cis-lunar space.  Doug sent in questions about heavy lift versus using already large commercial rockets.  Dan and Doug discussed this, then later in the second segment, Doug asked more questions on this topic.  For now they talked about going to Deimos with a Falcon Heavy.  Dan pointed out the need for many more launches and rendezvous missions as compared to one or two SLS type rocket launch.  He questioned if we can’t afford SLS launches, how do we afford even more launches and rendezvous missions.  Marshal emailed us wanting to know about the possibility of lava tube plans .  BJohn asked this guest about a possible Mars cycler & then we moved to the second segment.

In the second segment, I asked Dan what he thought the impact on space policy might be vis a vis the workshop being discussed on this program.  Don’t miss his reply.  Doug asked a question inquiring if for the same cost it would take to send humans to either Deimos or to the Martian surface, one could send many high-latency rovers to multiple locations far from each other to give the rovers many chances to discover evidence for life in different types of places?  This brought us several exchanges comparing LLT with HLT, heavy lift versus smaller rockets and more.  Doug and Dan has several exchanges during this segment, especially when the topic of rescue missions came up.  Ted in Boston asked about the rational for going to Mars, referenced the recent program with Dr. Zubrin, and the payoff or benefits for a human Mars mission.  Dan had much to say about this so don’t miss it.  John from Ft. Worth called to say we were not yet technically ready for Mars and we should use the stepping stone method and focus in cis-lunar development and exploration.  As an example, Dan & John talked about the need to know the actual gravity RX for humans. Dan said we should have a short arm centrifuge on the ISS helping to figure this out but that there was no policy to do that.  We turned to the topic of rescue and I told listeners what I found out about who pays for rescues when I did some quick and dirty research on this a few weeks ago.  The issue of rescue and how it might happen on a Mars mission or even in cis-lunar space came up with many listener emails including several by Doug putting forth various rescue scenarios.  For the most part, since we have no launch on demand, no rockets, pads or hardware sitting around ready to be used at a moments notice and we have to contend with launch windows, it does not seem feasible that a Mars rescue mission could be implemented, possibly not even a lunar rescue mission.  Doug suggested a scenario where multiple ships left for Mars at the same time and then if one got in trouble, the others could rescue the problem ship.  Dan talked about the physics and mass of what would be needed to do that. You decide if it might be feasible for such a rescue scenario to be implemented. Let us know your thoughts on the blog.  If the rescue party is already on Mars, rescue will be unlikely given the state of the art today.  Michael Listner suggested the absence of a realistic rescue plan may hinder the issuing of a launch license.  In his closing comments, Dan focused on the workshop critique saying that the sponsors would have been better served if participation had been opened up and had including human factors and aerospace medicine professionals.

We welcomed back to the show Greg Meholic to speak about advanced propulsion concepts, rocket reusability, and much more.  During the first segment of our 84 minute program, Mr. Meholic first defined what he meant by the term advanced propulsion.  Given this definition, we moved forward to discuss various concepts, propulsion methods, and propulsion research. During this segment, we talked about several propulsion technologies and Greg said thumbs up or thumbs down to their being advanced propulsion.  When it came to nuclear, Greg classified it as an alternative propulsion method, not an advanced propulsion.  Again, don’t miss his definition.  We talked near and intermediate term advanced propulsion concepts though it does not appear anything is really close at hand.  His timeline for a possible advanced propulsion technology was around 20 years.  He said not only do we need to understand the physics much better,  but the propulsion method much compete with current systems and produce benefits including cost benefits.  As far as choke points on advanced propulsion, he said understanding the fundamental physics involved was a big one.  We then talked about funding which is now mostly from companies and other private investor oriented sources.  I asked lots of questions about funding, especially how does one know when the point is reached to either kill the project or keep it going.  Don’t miss what he said about this.  Listeners also asked many questions.  In replying to one listener, he said it would be hard to beat chemical rockets to LEO but the door opens up BLEO though the Moon can be done with chemical rockets.  When asked about the anti-nuke movement and the impact on the nuclear rocket, he had some interesting observations, especially regarding the views of younger people.  When asked for leading advanced propulsion people and concepts, he mentioned former Space Show guest Dr. James Woodward and his work with Mach’s Principle several times during our show.  Greg was also asked about the work of Dr. Sonny White at JSC for warp drive and M drive.  Greg had much to say about his work including Q thruster and M drive.  John from Ft. Worth called in to talk about M Drive & Mach’s Principle along with gravity and magnetic frequencies.

In the second segment, Ashley sent in an email asking about going to the Moon and Mars for settlement and sustainability, wondering if advanced propulsion was needed for either location.  You might be surprised by Greg’s response to this question so listen carefully.  He did say there would be different requirements for the Moon and Mars.  With Mars, he also spoke about radiation and travel times.  Greg then had some things to say about artificial gravity.  One of his comments was that if we understood more of the physics, an eventual advanced propulsion system might enable an artificial gravity system without spinning or the need for tethers.  Brad in Tucson sent in a note asking about reusable first stage rocket launch systems.  Greg was delighted with the question as he works on such systems in his day job and he had much to say and offer about reusable first stage rockets.  He went through a brief summary of some of his work plus those attempting to design such systems including SpaceX.  I asked about a payload penalty with reusability.  Don’t miss his answer.  Our next caller was Marshall and he took us back to the artificial gravity discussion.  Marshal was asking questions about the amount of time spent in 1g as opposed to various fractional gravity loads.  As the program was ending, Greg received the final question which dealt with comparing the quality of government research to private sector research.  He reminded the listener that there very little to no government research funding for advanced propulsion, that it was almost all private sector funding.  He said the private funding was investor based so it comes with a commercial profit focus.
