Welcome to this two hour discussion on a variety of space topics per listener emails and calls.  During the first segment, our first caller was Dr. Dough Haynes of Blue Ridge Nebula Airlines.  He wanted to talk about his books as well as his advanced propulsion vehicle in the form of a “flying saucer.” He also spoke about starting a drone business and his Open House later this month in the Denver area.  Visit his websites for more information, http://www.blueridgeairlines.com,  http://bluenebula.com.  Given we were at the 10th anniversary of the winning of the X Prize, I asked Doug about his progress as well as the industry’s progress in doing suborbital tourist flights.  He had some interesting comments specifically addressing his technology projects.  I also read an email from B John in Sweden who commented on the Boeing-SpaceX award for commercial crew based on the information I put out in the introduction of today’s show.
Doug from S. California called next and told us about his plans to develop and build an inflatable lunar hab module, perhaps at the UofA in Tucson,.  He went on to describe the hab including materials and size.  He also said this would be supportive of his lunar conference he is planning for Oct. 2015 in Flagstaff, AZ.  He wanted more information, possibly from listeners, regarding sanitation issues in space and recycling human waste.  Toward the end of his comments, we talked about the recent lunar tourism article “A Lunar Road Trip” by Dr. Spudis, http://www.spudislunarresources.com/blog/a-lunar-road-trip.

In the second segment, I read an email from Luis in Venezuela which I will post on the blog on his behalf.  Though it was addressed to Dr. Doug in S. California, others may be interested in it as well.  Our next caller was SLS John in Ft. Worth.  John wanted to talk about the Boeing-SpaceX NASA commercial crew award and why Boeing was rated higher than the other parties.  He spent some time explaining his thoughts, then Alan sent him an email asking if he had finally changed his mind on SLS.  John had not and again explained his SLS position.  I suggested an SLS debate on TSS show with him and Rick Boozer who I will invite for such a program. I did get John to agree to do it.  Before John ended his comments, he brought up the recent Dr. Don Lincoln show about alien contact and UFOs and such.  This turned into quite a discussion about the topic which I really like but admit to very little credible information and evidence existing.  After John left the phone, Marshall called in to say that both sides of this argument often come to the table with their specific interest at the top of the list and that makes it even harder to study as a serious issue.  I also went over the upcoming Space Show schedule during this segment.

Post your comments/questions on TSS blog above.  You can reach any of the callers or those sending in emails through me.

We welcomed NASA Astronaut Dr. Rick Linnehan to the program to discuss animals and their place in space in history, the present, and the future, plus human concerns for long duration spaceflight.  During this one hour program, we stared off by asking Dr. Linnehan for an overview of the role played by animals in space, including looking to the future for animals for agriculture, research pathology work, comfort, & other purposes.  We talked about microgravity issues and countermeasures, then I asked specifically about taking chickens to Mars for feed purposes.  Our guest talked about the effect of microgravity on chickens and the egg laying process.  He said a few times that while we might likely evolve over many years, decades or even longer to having a larger role for animals in space, most of the ideas and concepts today are pie in the sky.  We talked about some of the animals that had been and are in space including lab rodents, fruit flies, some small fish and others.  Our guest talked about the space acclimation process for animals, including the small fish, and we learned that in many instances the animals acclimate to microgravity faster than humans.  Our guest mentioned the need for advanced propulsion for long duration human spaceflight and suggested that Mars was on the edge of the possible using chemical rockets.  Rick mentioned some of the other human factors issues such as radiation and psychological challenges.  We also discussed astronaut exercise routines and the countermeasure exercise equipment currently being used with efforts underway to redesign the equipment to be more effective and lighter.  Several questions came up about private sector humans to Mars missions and crew health.  When asked if we could do a humans to Mars mission now or by the early 2020s, our guest said yes but listen to the details of this discussion.  Also, with regards to the private astronaut missions to Mars or elsewhere, several questions arose about the conditioning of the private astronaut crew, what microgravity countermeasures and exercise equipment they would have on board, what routines they would strictly follow and more.  Our guest was mostly referring to space agency astronauts in terms of our readiness to do human spaceflight to Mars now or the very near future.  He was unable to address private astronaut missions or their details because they are unknown.  We did talk about gravity and the absence of it in spaceflight, both for humans and animals.  Advanced propulsion questions and comments kept coming up during the entire show. At one point, I asked how essential advanced propulsion was for long duration human spaceflight and he said there would be no long duration spaceflight without.  Listen for the details regarding his opinion on this issue. Doug called to ask about bacteria, DNA, cat implants and more.  Artificial insemination came up with regards to surrogate species.  Doug also raised questions about the size for a minimum viable population.  After Doug’s call, I asked what our guest thought the priorities should be for Mars human spaceflight.  He listed advanced propulsion technology as first followed by human quality of life issues which he described for us.  I also asked questions about crew compatibility for psychological reasons as well as the probable command structure for the crew on a long duration human spaceflight.  One listener asked Dr. Linnehan about the differences in a zoo vet as compared to the typical vet we use for our dogs and cats.  Larry emailed in to ask if an animal had ever been on a space walk.  Rick said not his knowledge, talked about the need for an animal EVA suit of which there are none, and when I asked about taking an animal with an astronaut on an EVA for research purposes, he explained why that was impractical.  The microgravity simulation work in the NASA neutral buoyancy pool came up and our guest said that for about every hour he spends on an EVA, he would have spend about 12 hours in the pool.  Near the end of our hour long discussion, Jack emailed in for the best goals for human space flight.  Our guest suggested evolving stage by stage with cislunar, La Grange points, lunar settlement and out further and further to other destinations as our capabilities and technology improved.  B John had emailed in a few questions about microbes and the sea plankton announced by the Russians as existing on the outside of the ISS.  While we discussed these questions earlier in the show, near the end I asked our guest his question about microbes traveling greater distances in space than humans have and if our missions that have entered interstellar space carry microbes with them.  In his summary, Dr. Linnehan stressed the importance of continuing to explore space, to leave our planet, set up settlements, and to do what we can to keep pressure on the policy makers as we know the importance of space development and exploration.  He supports the private/commercial efforts and missions and even suggested he would do a one way Mars trip to help open up a Martial settlement.

Welcome to this two hour open line discussion covering a wide range of space topics.  During the first segment which was half an hour, I introduced the program and some possible topics, plus I spoke about having attended AIAA Space 2014, the SmallSat 2014 Conference which was held the same time as AIAA, and I referred back to my having also been at the NewSpace 2014 conference.  Some possible topics of interest for discussion included a recent news story about astronauts usage of sleeping pills while on orbit.  Nobody seemed interested in that topic as it was not discussed during this program.  I also noted the huge gap between those working SLS or having an interest in it and those on the side that hate it and think it’s a huge waste.  As I said, the gap was wider than the Grand Canyon with no signs of narrowing.  This issue was raised during the second segment of tonight’s program.  You can read Duane’s article on the lessons learned astronaut panel I mentioned on air at http://www.aiaa-space.org/Forum.aspx?id=24589.

We paused for a short break and we opened the second segment with a call from John in Ft. Worth.  John remained on the phone for quite some time and we covered lots of topics.  Initially, SLS John, as I like to refer to him, went over his SLS place holder theory again.  We did spend lots of time talking about SLS, the gap between supporters and haters of the project, its operational plan, congress, and more.  We also talked Falcon Heavy which John suggested was potentially less real than SLS though I countered that thought.  We talked about the RD-180 rocket motor problem, and I told him & the listeners about some of my AIAA discussions, interviews including my breakfast with Dr. Mike Griffin & Frank Van Rensselear of Schafer Corp.  We also talked Dream Chaser and the press conference SNV held at AIAA, plus I talked about my interview with Larry Price, Deputy Director of Orion.  John said his real interest in space was advanced propulsion, specifically nuclear. Somehow our conversation ended up talking about Area 51 and the Clinton era lawsuit against the government by workers exposed to toxic materials.  As soon as John got off the phone, Dwayne called in.  He clarified the Area 51 story for us as well as the old litigation that the workers won but then Pres. Clinton used an Executive Order to overturn the court decision.  Dwayne also spoke about 3D printing in space and the recently concluded NRC 3D Printing In Space(http://www.nap.edu/download.php?record_id=18871  note you may need to open a free account to download the report for free).  There are also lots of news stories about the report should you care to research it.  We talked about 3D printing in space, how it might be used, and the possibility of a later metal printer in space.  Dwayne then spoke to the old Coke and Pepsi wars in space several years ago and he addressed the gap with SLS supporters and those that are against it.  He said it was a huge gulf and that he thought both sides may have less than a firm grip on reality regarding SLS.  In addition to the two calls, we fielded an email from Doug who brought up space settlement, the value of attending space conferences, and the commercial crew down select process.  Tim was our last caller and he brought up SLS again, we talked about the congressional candidate on the independent side in the Huntsville district, Mark Bray in that Mark works on the SLS project and that it would be interesting to know his space policy views since he might win the congressional election.  Tim also mentioned a article about Elon Musk in the NextBigFuture.com re an eighty thousand person Mars City by 2040.  You can download the article at http://nextbigfuture.com/2014/08/elon-musk-timeline-and-extrapolation-of.html.  The final email was from Joe in Houston wanting to know the NASA down select process & who might be responsible for it.  I could not answer his question but please, if any listeners know the answer, post it on the blog.

As always, please post your comments/questions on TSS blog above.  You can reach any of the email listeners or the callers through me.

We welcomed both Dr. John Jurist and Dr. Jim Logan back to the show to discuss spacewalks (EVAs), spacesuits, human missions to the Moon and Mars, to the Martian Moon Deimos, the newly created Space Enterprise Institute, & the new Aquarius Reusable Human Spaceflight water based launch vehicle.  During the first segment of our 2 hour 5 minute program, our guests started talking about EVAs.  Early in the discussion, Dr. Logan provided us with important & interesting statistics regarding EVAs, then we discussed the challenges with them and spacesuits.  We talked at length about the difference in EVAs and spacesuits for the Moon, LEO, asteroids, & Mars.  We also talked economics for spacesuits given the need for a specific spacesuit depending on the destination/mission.  We talked about new designs for one size fits all & for mitigating dust problems.  Jim talked about the medical complications regarding both lunar and Martian dust.  Our guests then suggested that EVAs will likely be phased out for robotic missions.  Doug asked several questions about this via email.  Also, Jim suggested that EVAs will evolve to the concept of Forward Deployed Humans in the Loop for Telerobotic Operations.  This concept was discussed several times throughout our program.

In our second segment, Jim started with an announcement about the Space Enterprise Institute (SEI).  When it goes live in the next week or so, I will announce it on the show so you can follow it  He explained SEI, its purpose & goals.  He then talked about the concept that both Jim and Dan Adamo have developed over the past few years, Aquarius which is a reusable water-based interplanetary HSF transport.  As soon as the SEI website is online, listeners will be able to download their peer reviewed paper for free.  During this segment, Jim talked about Aquarius, John added in some details, we talked about the need for nuclear electric propulsion and why, plus the role of water with this launcher.  Both our guests explained the advantages of Deimos for the early missions, plus the return shielding and reusability as the return goes to a lunar orbit using existing water.  Radiation shielding was talked about, including the needed water and needed Radiation Protection (RP) levels.  John pointed out one advantage of Aquarius was the use of an open loop life support system.  John in Ft. Worth called about the temperatures that Jim said were needed.  Jim explained the need for 3,000 degrees C.  Both guests offered closing comments about EVAs & the direction we might be heading toward the forward deployed humans concept.  Both guests said the telerobotic concepts discussed would reduce risks, timelines, & overall mission costs.

We welcomed Anthony Young to the program to discuss his book “The Saturn V F-1 Engine: Powering Apollo into History.  This is an excellent book which I strongly recommend.  Remember, if you buy it through the OGLF Amazon portal, Amazon makes a contribution to The Space Show.  During the first segment of our two hour program, Mr. Young started out talking about the book and why he wrote it.  Since our guest had also written books car engines, I asked him if there were comparisons to be made with the F-1 & the large, complex, & powerful car engines. We also talked about potential plans to rebuild and modernize the F-1 for either the SLS or as a possible engine replacement for the Air Force RD-180.  Anthony did say that it would not be a rebuild of the F-1 but a complete remake of it with modern manufacturing, materials, etc.  Another topic discussed was the F-1 thrust for a new engine.  Marshall called to talk about fuel propellants for the F-1 and air pollution.  This gave Anthony the opportunity to talk about ATK and their efforts to modernize the SRB & solid rocket propellant.  Anthony suggested that we need advanced propulsion for humans to Mars to significantly reduce the transit time, not a new F-1.  Michael called in & talked about SLS being needed to preserve the expertise & knowhow for making large rockets & flying them.  He also spoke about some of his upcoming Space Review articles on the Code of Conduct & other subjects.  He brought to our attention a YouTube video, “The Engines That Came Out Of The Cold” (www.youtube.com/watch?v=MZnYr94aa9E).  Mr. Young was asked about the existence of NASA lunar programs.  He mentioned several including Lunar CATALYST but suggested they were small robotic missions.  He did not think there were NASA human flights planed for the Moon.  Dwayne called to shed further light on NASA and lunar programs.  He also spoke about the F-1 thrust for a new engine.

In the second segment, John called from Ft. Worth.  He spoke about technology and performance for the engine, other programs now cancelled & the logic of having stayed the course.  He brought up good points on our losing our technology capability, then Anthony addressed many of the NASA KSC infrastructure changes going on to partner with the commercial industry.  Doug called to talk about some of the lunar program comments, to offer a different perspective on SLS, & public/private partnerships as well as international participation.  Anthony was asked for his thoughts on where our space program might be today had the Saturn V & F-1 not been cancelled.  In responding to this, he talked about how complex the F-1 was & how many parts were in it.

Please post your comments/questions on TSS blog above. You can reach Mr. Young through me & you can read his articles published on The Space Review.

We welcomed Alan Boyle back to the show for this 1 hour 42 minute discussion on numerous space news items & topics.  During our first segment, Alan talked about the “two year rule” which suggests space tourism & suborbital commercial flights are just two years away.  Throughout the program Alan kept suggesting that 2014 might be the end of the two year rule!   Alan gave us an overview of the spaceflight companies building vehicles.  Our next topic was the Yamato Meteorite, a Mars meteorite that may indicate past life on Mars.  He compared this to the 1996 meteorite announcement and said that some of the Yamato team members were the same as those addressing the 1996 “discovery” (www.nbcnews.com/#/science/space/tiny-blobs-tunnels-meteorite-revive-debate-over-life-mars-n38431).  In talking about Mars, I brought up the Viking experiments by Dr. Gil Levin , then a listener emailed in a question about the UK Tom Bower book on Branson, “Behind the Mask.”  Georgia followed with a question about the forthcoming NASA commercial crew down select, then I asked Alan for his view of SLS.  Alan said it definitely had a role to play.  Allison called from her car to inquire about private space stations & microgravity issues.

In the second segment, we discussed Planet Labs & their recent launch of cubesats from the ISS.  Alan also explained how the cubesats were launched from the station, plus since he had seen some of their images, we got a report on image quality.  Todd emailed in a additional question about cislunar transportation/lunar settlements.  Alan had several questions pertaining to what would actually be done in a lunar settlement.  Elon Musk & his Mars plans came up and we spent a few minutes talking about that subject.  Alan said the biggest dud story of 2013 in his opinion was Comet Ison.  John called from Ft. Worth & I queried him again on SLS but he actually wanted to discuss Mars & present day capabilities.  He then talked about the need for advanced propulsion for Mars flights.  He said he would back off his SLS support had there been plans for a second generation shuttle, depots or something that would be a real program.  He said SLS was a real program & any program was better than no program.  Alan then said he was looking forward to 2015 with New Horizons, Dawn, & SpaceShip2.  He also mentioned the ESA Rosetta mission,  then as the show was ending, he was asked about the Chinese lunar rover.  The final question from Sara was about the value & importance of human spaceflight.

We welcomed Adam Crowl to the program for a one hour twenty minute discussion on interstellar travel, propulsion and technology potentials.  During the first segment, we talked about the book Starship Century and his chapter in it, “Starship Pioneers.” the early rocket pioneers and their thoughts on interstellar travel as the idea as it has has been with us and our imagination forever.  We talked about theoretical backing, actual capabilities, time lines, and more. Some of the technologies were addressed such as nuclear fusion plus some of the models he showed pictures of in his chapter in the book.  We also talked about solar sail and then I asked about human flights to Mars and the Moon as stepping stones for interstellar flight.  Antigravity was discussed along with antimatter, lasers, proton beams, and more. Our callers asked about these futuristic technologies and even the types of interstellar missions that could unfold down the road.

In the second segment, faster than light travel came up with Dr. Harold (Sonny) White and his work.  More calls came in regarding gravitational theory, particle physics, and beam propulsion.  Another John called in wondering about the accuracy of today’s interstellar speculation.  Multi-generational starships were discussed plus Adam made a point saying the profits from the book go to support interstellar research.  Check this out at the book’s website, www.starshipcentury.com.  As the program was ending, Randy sent in a note about the inspirational and motivational value of interstellar travel discussions.

We welcomed back to the program Dr. Dennis Bushnell, the NASA Langley Research Center Chief Scientist.  Dr. Bushnell discussed his paper, “Advanced-to-Revolutionary Space Technology Options-The Responsibly Imaginable.” which can be downloaded at http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20130011698_2013011376.pdf.  In the first segment of our 1 hour 26 minute show, Dr. Bushnell summarized the findings in his paper and talked about how we are still building on technologies from the 50’s and 60’s that were based on “living better with chemistry” and ICBMs.  We began talking about advanced propulsion including nuclear, but our guest made it clear throughout our discussion that what was needed was a reduction in the cost of space access by a magnitude of 10, not by two which is what is happening with new commercial rockets coming on line.  In fact, later in the show when discussing commercial space, Dr. Bushnell was clear that to close a commercial space business plan the reduction in launch costs by a factor of ten was absolutely essential!  I asked our guest to tell us where the bottlenecks were and he said it was in the culture & big cultural changes were required to move forward.  He also talked about the need to experiment and try lots of options and ideas, to triage them, down select, fly them, and choose the best based on the engineering process he described.  We talked about the low technology readiness level (TRL) of many of today’s space ideas and technologies, that we have become focused on instant or near instant gratification but that the process he was talking about would extend over a 25 year period.  Given this, his paper is a frank and factual discussion of many of our space industry segments, a no nonsense, no Kool Aid TRL analysis of much of what we talk about and say we can now do in space or will be doing in the near term.  Safety was discussed, including microgravity, radiation, plus a mention of unknowns regarding what we already know about gut bacteria exposed to radiation given our limited amount of research on this topic to date. A listener asked him about physics as a main reason for space exploration and contrasted that to settlement as the main reason for HSF. Another listener asked him about his mentioning USAF comments that indicated space was a mature and declining industry.  We began talking about commercial space, but we talked about it through the second segment as well.  In this segment, Dennis talked about how we have created economic growth in the past but now we have not only the challenge of economic growth but sustainable jobs and sustaining our standard of living.  Terraforming Mars was discussed as part of our discussion about Inspiration Mars and Mars One HSF missions to Mars.  As this segment ended, a listener asked him about suborbital space and citizen science projects.

In the second segment, John Hunt called in to talk about the high cost of many advanced space technologies, plus he wanted updates on LENR (this used to be called cold fusion).  Dr. Bushnell had much to say about LENR and it potential, we talked about Rossi, and the NASA work being done to better understand LENR effects. With an understanding of it, funding would not be as big a problem as it is today.  He also said LENR had the potential to be transmutational.  Our guest suggested that for more information, we visit the Larsen LENR slideshow:  www.slideshare.net/lewisglarsen/slideshows.  Again, he pointed to cultural issues as major stumbling blocks to this research.  In returning to the focus of his paper, he said there was no shortage of ideas but the culture was preventing them from being tried, tested, and exploited.  Rocket reusability was brought up, our guest mentioned the SpaceX Grasshopper work, and he was asked about SLS and fuel depots.  I asked about BLEO issues and radiation.  In response to another question, he said that were he the space guru, he would focus on “energy” and structural materials. You will want to hear this discussion. Later, Tim called from Huntsville about radiation and HSF to Mars, as well as the economics of the Big Dumb Booster.  I asked Dennis about the target audience for his paper and he said it was meant for NASA and the world since space fairing is a world endeavor. He again talked about potential revolutionary technologies which are needed and which would benefit all of us.  He repeated that we must do the difficult and take the risk and invest.  We also need to look forward with multiyear planning.  Near the end of the program, Dennis was asked about space elevators which he was not enthusiastic about.  Again, he repeated that we needed to make investments to raise our TRL levels.  At the end, I asked why space does not rise to importance in presidential campaigns & elections.  He said space was very good as an Earth utility but beyond that, there was no clear basis for most of it and that was the problem. Don’t miss his comments on this topic.  Our final topic was his assessment of commercial space given his years spent working on it with NASA including budgets into the hundreds of millions to find a way to close a commercial space business case for commercializing the ISS and other things.  This is a very important short discussion, don’t miss it.
