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

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

We welcomed Dr. Tom Matula back to The Space Show for a 1 hour 46 minute discussion about Tom’s concept for space settlements known as astrosettlements.  His Power Point presentation given at the ISDC 2013 has been uploaded to The Space Show blog for your review.  In the first segment of today’s program, I started out asking about one of Tom’s previous theories, the Space Development Bank.  From there, we jumped to astrosettlements which Tom believes will be market driven so we discussed some of the market factors that could drive these settlements.  Astrosettlements are orbital and would be designed for 500 to 1,000 inhabitants.  He listed three characteristics for the astrosettlements and we discussed each one.  The three included the need to be autonomous, mobile, and expandable.  Doug called from S. California to talk about and clarify market demand.  This led Tom to discuss the potential of the SpaceX Dragon Lab.  He also talked about suborbital with his understanding that the killer part of suborbital would not be space tourism but instead atmospheric research.  I asked Tom for timelines for the astrosettlements and he said 2-3 decades. This sparked further discussion.  When I asked for the starting point to develop the astrosettlements, Tom said we would need to develop virtual world models.  This resulted in a rather comprehensive discussion of modeling in the virtual world with Charles calling in to disagree across the board with our guest.

In the second segment, I read a lengthy email from Carl in San Antonio that deal the lunar development, the Moon Treaty, Common Heritage of Mankind and benefit sharing issues.  Don’t miss this discussion. Paul Turner both emailed in and called regarding how to profitably develop real estate in orbit, and why it is financially sustainable.  Paul has a book coming out on this topic so we will hear more about this later on.  More timeline questions came up regarding astrosettlements and the potential early market drivers which might include intellectual property, early materials manufacturing, and raw materials.

Please post your comments/questions on The Space Show Blog URL above.  Tom has a blog you should check out, www.wealthofspace.com.  You can reach Tom through me or his blog.

We welcomed Howard Bloom back to the show for this two hour 6 minute complex space policy, leadership, commercial space and more discussion.  During the first segment, Howard worked us into discussions about space and pop culture, space leadership and policy issues, commercial and private space issues, and the SLS as representative of extreme pork taking down the space program.  This conversation included many side tracks including space art for inspiration, Von Braun, Chesley Bonestell, and more.  We talked about The Space Development Steering Committee, their focus on private space as well as space solar power (SSP).  As you listen to this program, you will realize this is not an ordinary Space Show discussion on these topics as Howard brings to us very unique and very broad important perspectives with important information.

In the second segment, Chuck Lauer called in to talk about the Darpa XS1 suborbital program and his company submission.  Later, Howard talked about Dragon and Cygnus plus the significance difference between the two.  He advocated for fuel depots and space infrastructure.  I asked Howard about a timeline for realizing the development/implementation of the project he was talking about.  He also talked about the ISS, Mars, Phobos, and L1.  Near the end of the discussion, Howard talked about his two Kindle books available on Amazon, “How I Accentually Started the Sixties” and “The Mohammed Code:  Why a Desert Prophet Wants You Dead.”

Please post your comments/questions on TSS blog.  Howard provided his social media and email address during this show for contact and for joining The Space Development Steering Committee.

We welcomed Tom Olson back to the show for his 2013 space year in review.  Note that this program was pre-recorded on Dec. 19, 2013 for play today, Dec. 31, 2013.  During the first segment of our two hour program, Tom began the review by talking about the Chinese lunar lander now on the Moon.  He expressed concern that Russian and the U.S. may be left behind though we did talk about the private U.S. lunar missions working on getting back to the Moon ASAP.  Tom next talked about NewSpace successes during the year, the successful completion of the COTS program with both the Orbital and SpaceX launchers taking supplies to the ISS.  Tom suggested commercial crew was on time for 2017 and that SpaceX was making good progress with Grasshopper and potential reusability.  He talked about controversy over Pad 39A evelopment, the recent Dream Chaser accident, and the emergency of commercial markets for the ISS with CASIS and Nanoracks. Before this segment ended, Tom talked about the impact of sequestration and space politics for the industry as a whole, then he addressed SLS.  As the segment was about to end, he named a few of the 2013 busts including NASA Redirect Mission, Inspiration Mars, and Mars One.

In our second segment, we talked about space advocacy during the year and the success of the 2013 NewSpace Business Plan Competition. Space settlement was discussed and as was NewSpace outreach, including congressional outreach.  Tom talked about progress with the suborbital companies and Virgin Galactic.  This took him to the space tourism topic and the 2014 planned Virgin Galactic operational flights.  Our guest was asked about the regulatory issues in 2013 and what he thought they would be like for 2014. For the most part, he predicted no change.  We talked about financing space ventures and capital acquisition for 2013 as well as start-ups and space entrepreneurs.  He also mentioned Armadillo Aerospace going dark during the year and mentioned the risks to the emerging commercial industry if funds become scarce or hard to obtain.  Though this was a pre-recorded show, there were some advance email questions for Tom. One near the end of the program asked him about plans to do anything with his Colony Fund program.  Tom said it was a great idea but 12-15 years ahead of its time and may someday be brought back to life.  That said, he reminded us that the Colony Fund did advance the space scalable strategy.  Before our discussion ended, Tom updated us on the activities of Walt Anderson and his new ventures.

Welcome to the final program of our Golden Oldie series, The Space Decade In Review. For this program which originally aired on Dec. 31, 2012, 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 Bill Harwood, the CBS News space consultant to the show.  During the first segment of our 90 minute program, Bill told us about his press conference and briefing with Elon Musk, the CTO from SES, the company sending the first GEO bird to orbit on the Falcon 9 on Monday afternoon, 11-25-13, and Ms. Shotwell of SpaceX.  Most of the first segment was spent discussing the press conference, the comments about the launch made by all participants, the challenges of doing the first GEO launch for the new Falcon 9 V1.1 and more.  Not only did Bill go over the details of the launch and the SES satellite orbital insertion, plus the Falcon 9 plans for second stage firing and getting in position for the satellite to take over for its part, we talked about SpaceX launch costs, we compared the Falcon 9 costs as best we could to the Arianne and the ILS Proton costs.  Bill was asked about the thoughts of the Falcon 9 competition and what it might mean for a SpaceX success with their first GEO launch.  Also in this segment, Bill was asked about Inspiration Mars, SLS, & Orion.  Other topics included space settlement, suborbital flight, Virgin Galactic, robotic missions, and the why that justifies HSF.  As the segment was ending, a listener asked about the Florida space coast economy and its economic recovery.

In the second segment, Bill was asked if SpaceX was creating a new market or taking market share from the existing competition.  We talked about NASA story telling for a better space policy, the JFK legacy, & space being treated by many as a luxury.  I asked Bill about the private sector being able to kick start space industry development and Bill responded with information how hard space was, especially orbital space which requires speeds of 85 football fields per second.  Dream Chaser and its recent accident were discussed and there was lots of listener support for Dream Chaser as there was from our guest.  More was said about the potential market for suborbital tourism and flights.  Bill was asked about the biggest change over the years in his covering space issues and he said it was the change in politics.  I asked him about his reporting during both Challenger and Columbia. As the program closed, Bill was asked about the ISS, commercial development for the station, and the need to keep the station going beyond 2020.

We welcomed Dr. Taylor Dark to the program to discuss his chapter on space advocacy, “Reclaiming The Future: Space Advocacy And The Idea Of Progress.” Dr. Dark’s chapter appeared in a NASA book around 2007, The Societal Impact of Spaceflight.  The .pdf version is a free download at http://history.nasa.gov/sp4801-part1.pdf.  You can read Dr. Dark’s chapter at www.taylordark.com/NASA%20Chapter.pdf.  For more information about our guest, please visit his website, www.taylordark.com. I urge you to read Dr. Dark’s chapter before listening to this program.  During the first segment of our 2 hour 1 minute discussion, Dr. Dark told us about his space advocacy background given that he started the first high school L5 organization when he was around 14 years old.  From there, we talked about aspects of space advocacy and specific personalities such as Dr. Zubrin and Taylor’s early fascination with O’Neill colonies.  He then described his shift to a different view of advocacy during his undergraduate college days.  Taylor went into detail about advocacy being connected to the idea of progress for humanity and listed three major space advocacy claims: (1) No limits on growth or human capacity; (2) All good things go together meaning elements of progress are linked together & are reinforcing; (3) Innate Directionality meaning progress is always probable.  He discussed these claims on air but he goes into them in detail in his chapter.  The utopian or messianic view of some advocates was discussed.  Dr. Dark also pointed out that space advocacy was not the only outlet for science, progress for humanity, etc.  Next, he talked about the frontier idea which he said was a weak argument.  He cited many national experiences that had had no frontier and have done well with their space program.  A listener asked our guest for his three top space arguments which were space exploration for more understanding of the universe, planetary defense of potential NEO hits, & commercial activity that was really profitable.  John called in to talk about the need for low cost space access and RLVs which would in turn cause space advocates to engage in lots of potentially profitable ventures. 

In our second segment, Doug called to talk about the probable costs of the O’Neill vision including the lunar base, SSP, & the habitat.  He suggested space tourism was a potential scalable profitable venture and he talked about space and lunar settlement.  Doug also talked about propellant in Earth orbit and satellites from LEO to GEO.  I spoke with Doug about project financing and how commercial or public sector project viability is analyzed which was different from what Doug talked about.  Taylor suggested that advocates don’t typically engage in something like project financing, instead opting for solutions that fit their advocacy agenda.  Taylor talked about the challenges of many advocacy claims including HE3 and fusion and the need for large space settlements.  As we were ending the discussion, Taylor was asked about the possible impact of microbial life being discovered, past or present, or ET.  We also talked about advocacy for inspiration & education and the impact of the Chinese program on advocacy and civil/commercial space.

We welcomed Dr. John Cramer to the program to discuss his chapter in the book “Starship Century.”  Dr. Cramer titled his chapter Exotic Technologies for Interstellar Travel.  Remember, if you purchase this book using The Space Show/OGLF Amazon portal, Amazon will contribute to The Space Show.  Instructions for doing this are in all archived program summaries on our website and our blog.  Dr. Cramer’s website is http://faculty.washington.edu/jcramer.  During the first segment of our 90 minute discussion, Dr. Cramer talked about his chapter, interstellar spaceflight, exotic technologies, and the Quantum Grounded Theory.  He mentioned James Woodward and his work with Mach’s Principle.  I also asked him about the level of interest expressed by his students in interstellar travel and we talked about timelines for realizing interstellar travel.  Our guest said we needed breakthroughs and the progress in 100 years would depend on realizing key breakthroughs.  Dr. Cramer suggested that our challenges were still in the fields of theory as we needed much better understandings of lots of things associated with interstellar travel.  The issue of space settlement came up in terms of Mars and deep space.  We also talked about worm holes but we spent more time on that subject in the second segment.  I asked if finding the Higgs-Boson was helpful. Dr. Cramer had much to say on this as well as on the LHC and colliders in general.  Dr. Cramer was asked about his science fiction works and his writing for Analog.  We also talked about the impact of our having cancelled our collider to be built in Texas and the impact of that decision on American science for decades following that political decision.

In the second segment, Dr. Cramer went into more detail about worm holes, including an explanation of the “back reaction” issue.  Later, we talked about timelines, budgets and our political funding process.  Near the end of the program, NASA was discussed as was our reliance on large rockets.  Dr. Cramer said we would need to get away from rockets and propulsion thrust if we were to do anything with interstellar travel or deep space.  At the end, he was asked about ET based on the comments Dr. Davies made on his interview earlier this week.

Our first segment of this 2 hour 14 minute Open Lines program started with a few of my suggested topics including a recent John Strickland Space Review article on SLS followed by a response from NASA which was published in the Huntsville Times as well as on NASA Watch.  More about this later as a caller read the two articles, then called to discuss them.  However, our first caller was Dr. Jurist who called to mention and congratulate the UND Space Studies Department for the award they received from NASA: The JSC Certificate of Appreciation for 25 years of outstanding leadership in the interdisciplinary leadership of space studies.  During John’s call, I read the exact wording on the certificate and since John and I are both adjunct professors at UND SpSt, we had much to say about the program, faculty, subjects, students, founders, etc.  It’s a fine program and it was an honor to let all of you know about this well deserved award and the UND Masters and PhD program in Space Studies.  Next up was our friend Dr. Bryan Laubscher to discuss this year’s upcoming Space Elevator Conference to be held August 23-25 at the Museum of Flight in Seattle, WA.  See http://www.isec.org/sec for more conference information, registration, the agenda, and logistics.  We talked about new developments with the space elevator, and Bryan told us about two other projects, plus he mentioned launch loop for which you can get more information at www.launchloop.com.  John in Ft. Worth called as he read the two articles on SLS and the NASA response that I mentioned at the first of our program.  His bottom line observation on SLS did not change as he believes it’s a placeholder for both the space workforce and technology until better days favor the space industry.  We had much to say about what John Strickland said in his July 15 TSR article and the NASA response by Dan Dumbacher per his July 29th article.  You don’t want to miss this discussion.

In the second longer segment, Tim was first up to talk about Rand Simberg and his theories that space is not important and more risk is needed, not more risk averseness. Tim made comparisons to settlers coming to the New World and I challenged him on it but his bottom line is that most likely most of the population will not be interested in space or space settlement and eventually when technology advances and prices are significantly lower, private companies will take the lead into space.  This of course only related to human spaceflight.  Our next caller was Mr. Microlaunchers himself, Charles Pooley.  Charles was again making the case for his approach to space through Microlaunchers (www.microlaunchers.com) when Dr. Jurist called in on the guest phone line to challenge Charles, especially about financing, time lines, ROI, etc.  John kept pushing Charles for how he intended to go from A to B.  It was a good discussion with John and Charles, one you will certainly want to hear.  John from Ft. Worth called back to talk about a possible rocket shape modeled on the Aquapod water bottle used by Ozarka Water Company. When I told listeners how to see it on the web, Charles emailed back saying the design would not work for a rocket. Oh well, back to drinking the water from it, I guess.  Our final call was from Jeff in Tucson who talked about his recent tour of Surrey Satellite when he was visiting in the UK.  This is an extensive description with very good and important observations.  Since Jeff has also visited SpaceX, we did some compare and contrast analysis between these two state of the art companies, one in the UK and one here in the states in S. California.  Also, you will want to take note of Jeff’s keen observations regarding Surrey and what makes it tick, including the cost free relationship it has with the Surrey University and its undergraduate as well as graduate students, many of which eventually come to work for Surrey Satellite.  Again, this is a very interesting discussion.

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.
