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 back Rick Boozer to continue discussing his premise that congressional mismanagement as adversely impacted NASA and that money going to SLS is money better spent elsewhere.  During the first segment of this 1 hour 45 minute program, Mr. Boozer reintroduced his book to us (he was a guest on TSS regarding his book on August 12, 2013), talking to us about adverse congressional management of NASA the why he believe SLS is damaging to NASA.  Mr. Boozer is very effective in sating his case, with lots of passion.  He references earlier proposals by ULA and SpaceX to build larger heavy lift rockets than the full size SLS for a fraction of the SLS cost but those proposals were dismissed, paving the way for SLS.  We also talked about private sector efforts in making rockets rather than the government doing it, also COTS and Commercial Crew.  At times I countered Rick’s perspective with a few of the better known pro-SLS arguments such as SLS is a place holder for key parts of the aerospace workforce.  Don’t miss what Rick had to say about this idea.

In the second segment, Doug called in with SLS questions based on the assumption that SLS does fly.  Our guest talked about a heavy lifter not needed for the Moon but most likely needed for human spaceflight to Mars.  Another listener asked Rick if he had a Plan B if SLS continued to be funded.  Rick said the Plan B is today’s status quo.  During both segments of this program, our guest mentioned SLS & competing private heavy lift vehicle studies carried out by Dr. Alan Wilhite of Georgia Tech.  Rick provided me with several URLs to this information.  Check out this information at www.newspacewatch.com/docs/IAC-12.D3.2.3.x15379-NASAStudy.pdf & http://spirit.as.utexas.edu/~fiso/telecon/Wilhite_2-13-13/Wilhite_2-13-13.pdf.  Also, Rick suggested a debate on the SLS topic.  I would be willing to do a Space Show debate with Rick opposing SLS.  If you have a suggestion for someone to represent support for SLS, please let know.  Toward the end of the program, we asked Rick about his future book plans and he talked about a crowd funding program regarding the preservation of valuable astronomical data.  Also, visit Rick’s own blog, http://astromaven.blogspot.com.

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.

Guest:  Dr. Dmitriy Tseliakhovich.  Topics:  Escape Dynamics microwave beam propulsion for launches.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://thespaceshow.wordpress.com.  Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information.

We welcomed Dr. Dmitriy Tseliakhovich, CEO & CTO of Escape Dynamics (http://escapedynamics.com) to discuss their work on making microwave beamed propulsion possible for space launch.  During our 1 hour 39 minute discussion, Dr. Tseliakhovich talked about his background and passion for space, including helping to open up commercial space.  His work and experience led him to creating Escape Dynamics in 2010 to find a better and more efficient way to space than by using chemical rockets.  Dmitriy then took us through many of the benefits of external launch, including a higher specific impulse, better payload ratios, and even the ability to use an SSTO frame for the vehicle.  During this segment, we also talked about safety issues and using the possibility of using the technology as a space weapon.  During this discussion, Dmitriy was very focused and precise in saying that their systems had to prove out as being safe on all of the issues we were discussing. Next, we learned that the initial beamed propulsion vehicles would be robotic but at some point in the future, eventually crewed launch vehicles would be possible.  We talked about their step by step incremental development and testing plan, including starting with suborbital launches.  I asked our guest about the probable cost of electricity and support from the existing electrical grid.  Our guest had much to say about the cost of electricity, the use of the grid for their power needs & the capability of existing systems to support their needs.  He also did not rule out partnerships with utility companies.  Listeners sent him emails asking about competition and markets as well as the use of hydrogen for fuel.  Our guest was also asked about their heat exchanger, a key component on the vehicle.

In our second segment, Dmitriy was asked about weather issues for launch & we learned that there were concerns and requirements suggesting launching in dry areas would be best.  Another listener asked about ocean launch possibilities & Charles called in expressing skepticism, to support chemical rockets, and to raise questions about the high g force, boost stations, and the size of the ground array needed for the beam propulsion launch system. Roger emailed us to ask about orbital fuel depots & beamed propulsion.  We then talked about the company timeline & learned about 2015 as a suborbital launch target date.  In response to an email about the main challenges, our guest said the challenges to the system were mostly non-technical.  John was our last caller asking about DARPA, project financing, fuels, and more. In closing we talked about available internships and the hiring opportunities at Escape Dynamics.

We welcomed back John Strickland for this two hour discussion on a wide range of topics of interest to the NewSpace, commercial space, and space settlement audiences.  John started out by talking about the upcoming NSS ISDC Conference in San Diego from May 23-27.  For more information visit the NSS website, www.nss.org and click on the ISDC link.  Some tracks are still open for submitting abstracts so if this interests you, click on the appropriate link at the ISDC site.  During this part of our discussion, John talked about the NSS Roadmap and the planned coverage of it at ISDC 2013.  John was then asked about the deep space commercial and Mars ventures announced in 2012 and so far this year.  He said they were helpful to the overall space settlement agenda and explained how in his discussion comments.  He added that the Mars missions and Golden Spike were “laudable” but suggested we may not be ready by the time the projects give for doing the venture. He later said he would have spent the money differently.  Don’t his miss all his comments on these new commercial and HSF missions to Mars.  Our conversation then focused on the problems of sequestration and then John talked about heavy lift and SLS.  Our next discussion topic was Space Solar Power (SSP).  Here, John took us through a detailed analysis of why terrestrial solar and wind is not the best way to go, then he went through some of the characteristics of SSP and why it is the preferred way to acquire much of our energy. This is a detailed and at times marginally complex discussion but one you will want to hear.  In the end, he suggested we delay until we have the bigger launchers such as Falcon Heavy or bigger to make the launch component more economical.  His analysis included total energy needs for a city, Texas, the U.S., globally, etc.  It is a very instructive discussion.  Near the end, he said we should not put all our eggs in one energy source basket.  Listen to his solid explanation for this suggestion.

In our second segment, John talked about launcher reusability and more regarding SSP.  He introduced us to space logistics, commercial docking with cargo to the ISS, & the need for reusable deliveries, thus the RLV.  From here, he talked about fuel depots, mostly at Earth-Moon L1 and L2.  He explained the boil off problem, the cryogenic transfer problem, and the need for good insulation plus a cryo cooler.  Other issues in this segment addressed a lunar base, plausible time lines for accomplishing much of what our guest talked about, the Chinese space program and the complicated US-China relationship.  Near the end, a listener asked about a possible Texas spaceport per suggestions of SpaceX.  Tim called just before the end of the show to talk fuel depots, types of propellant for the depots and then he mentioned the VAPAK process (see http://ralph.open-aerospace.org/PDF/2009.04.14%20-%20HCG%20White%20Paper%20-%20VaPak%20Overview.pdf.)

Guest:  Jim Keravala.  Topics:  Shackleton Energy’s cislunar economic development plans.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://thespaceshow.wordpress.com. Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information. We welcomed Jim Keravala to the program to talk with us about the Cislunar development plans for Shackleton Energy.  To learn more, visit their website at www.shackletonenergy.com. Jim started our discussion with an overview of Shackleton Energy and their Cislunar development plan.  As you will hear throughout our discussion, the plan involves the propellant depots near the ISS and in other locations, water ice development at the lunar north and south pole, the use of insitu resources and eventually Shackleton industrial astronauts.  Our guest spent most of the first segment describing the plan, the various stages of development, the use of robotic technology leading up to human spaceflight and benefit sharing ideas.  He talked about being able to solve or at least significantly contribute to solutions to our global energy usage problems which he said would be around 30 terawatt hours(TWh).  He talked about the viability of SSP at that point based on the cislunar Shackleton Energy development program. Jim also mentioned the risk of reaching the Kessler limits regarding space debris.  Ben sent in an email asking Jim for his thoughts on benefit sharing, a subject put forth on The Space Show by recent guest Dr. Edythe Weeks.  Jim was supportive of benefit sharing through technology exchanges and transfers as well as in helping under developed nations build an industry to allow them to compete and have a presence in the expanding space industry.  He cited his work with Surrey Satellite Company and their African space development program as an example, plus he talked about sharing to make sure everyone benefitted from space development which could significantly improve life in these countries.  We talked about government corruption problems and ITAR as issues that might get in the way of benefit sharing, but Jim was steadfast in the need to reach out to third world countries to engage them in space development for the commercial and industrial benefits.
     In our second segment, Doug called to ask about transitioning from telerobotic missions to human missions.  Here, Jim did a comprehensive explanation of the different phases of their development plan leading up to industrial astronauts in cislunar space. He talked about trades with humans based at EML1 as compared to the lunar surface regarding repair and maintenance missions of lunar surface hardware.  Charles wanted to know about their choice of launch vehicles.  Jim also got questions about their timeline and capital acquisition plans.  Randy wanted to know if they would be able to meet the 2020 timeline referenced in their website video.  Near the end, Jim got questions about the requirements for becoming an industrial astronaut.  In summary, Jim talked about their ambitious project, TRLs, and the importance of the project from many different perspectives.

http://thespaceshow.files.wordpress.com/2012/11/adamo-eml2roundtripr2.pdf.  We welcomed Dan Adamo back to the program and Dr. John Jurist as co-host for this special webinar addressing trajectory analysis for an EML2 mission and more.  On The Space Show blog, you will find Dan’s PDF document used during the webinar, a link to the movie he played in the second half of the webinar, and his Phobos-Grunt analysis paper we discussed near the end of the webinar. During the first hour of the webinar, Dan took us through the trajectory analysis to Earth-Moon L2 per his PDF document.  We talked about why EML2, libration points in general, and how such missions are planned.  If the resolution on the webinar video for the charts and tables used during this segment are difficult to read on your computer, please bring the document up on the PDF on The Space Show blog and follow along that way.  Dan took us through Table 1, HALO orbits, and the HOI as well as the Trans-Lunar Insertion points.  We talked about orbital characteristics, delta V, rocket size, and more  We also talked about the position of the Earth, launch windows, the Moon, & other factors influencing the planning of the mission.  While at times the discussion may seem a bit technical or overwhelming for those of us having never done mission planning at this level before, all of us will certainly have a better understanding of the factors considered and influencing both robotic as well as human spaceflight missions.  Near the end of the segment, we talked about the SLS and heavy lift & how payload capacity interacts with mission & trajectory analysis. 
 
     In the second hour of our webinar, Dan took us through his HD movie of the orbital trajectory talked about during the first segment, stopping it at intervals for specific explanations and questions.  The movie is in the QuickTime format but you can see it both on the webinar or by using the URL provided on the blog.  We took several listener calls & questions.  One asked Dan about the differences in planning for the robotic vs. the HSF mission using MSL & Curiosity as an example.  Dan pointed us to a YouTube video he made a few years ago with Dr. Logan using these tools for a Deimos mission (www.youtube.com/watch?v=X10GAqA4Ky4). Another listener called wanting to know the likelihood of an EML2 mission actually happening.  Dan explained why he believed this mission to be the next stepping stone in HSF.  More was discussed about SLS with Dan raising some concerns about its real capabilities & wondering if Congress is being sold unrealistic expectations. We talked about heavy lift in general & with the support of properly placed depots.  SLS and the difference with a Falcon Heavy were also discussed in terms of what the differences would mean in payload, number of launches, costs, risks, etc.

Guest:  Dr. George Sowers.  Topics:  United Launch Alliance, Atlas 5, Delta IV, human rating Atlas and Delta.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://thespaceshow.wordpress.com. Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information. We welcomed Dr. George Sowers, VP of Human Launch Services at ULA back to the show for a special one hour report on Atlas, Delta, human rating rockets, and much more.  Dr. Sowers started off by letting us know that ULA recently created the Human Launch Services Division with Dr. Sowers as the Vice-President.  Dr. Sowers then updated us on some of their more visible ULA activities since his last visit to The Space Show in January 2011, including probable SLS and Dream Chaser time lines, commercial crew participation and Orion tests in 2014.  We talked about the ULA role in commercial crew and what was needed to human rate the Atlas as well as the Delta IV.  I also asked about needed pad modifications for HSF with an Atlas and Dr. Sowers told us about modifications to Launch Complex 41 at the Cape for the upcoming crewed flights.  Listeners asked our guest lots of questions about safety, pad modifications, range safety issues, and the difference in human rating the Atlas as compared to a Delta.  Another question asked of our guest was to understand the contributing factors to the impressive launch success and safety rate for the Atlas rocket.  Dr. Sowers answered this in some detail with attention being paid to what is known at the 3 P’s.  Charles wanted to know about the Russian RD-180 engines & another listener wanted to know if ULA was feeling competitive “heat” from SpaceX. Yves in Montreal asked about the dual centaur having uses other than for commercial crew and Barbara wanted to know about the role of an Atlas for possible orbital tourism with a Bigelow space station module.  We talked about ULA’s potential interest in new spaceports which seem to be developing around the country, then I asked Dr. Sowers about what constituted a commercial space project. Here, we learned that commercial implies largely financed by private funds, not government money.  He said that EELV was developed by 80% private sector funding.  We also talked about the Arianne family of rockets and their pricing which is subsidized by European governments.  Dr. Sowers explained why it was so hard to compete against government subsidized pricing.  Another topic of interest in our discussion was launch vehicle market and pricing elasticity and how to drive up launch rates and lower launch costs.  We also talked about human spaceflight having the government as the primary leader for the market and cargo as having only an ISS market at this time.  On orbit propellant depots were discussed as was SLS and heavy lift.  As we neared the end of the hour, we talked about SRBs for the human rated Atlas.
     In our brief second segment, I went over the near term Space Show schedule and our last caller John from Florida called in to wonder if a real emergency came up if we would launch a crewed rocket/vehicle to try to save the ISS for example or would we be unwilling to take the risk and let the ISS deorbit in the example given.  Hopefully such a predicament does not arise.
     If you have comments/questions about our discussion with Dr. Sowers, please post them on The Space Show blog.

Contact Dr. Livingston for questions about our copyright and trademark policies. You can see the webinar at https://vimeo.com/channels/thespaceshow.  We welcomed Dr. Jurist to this special two hour webinar on rocket mission, planning, risk, & cost analysis.  Dr. Jurist developed a series of copyrighted spread sheets for this discussion. Callers had the opportunity to “massage” the numbers to see what happened with costs, success probabilities, & how many launches might be needed depending on the rocket being evaluated.  We relied upon published data for all rocket systems discussed, even when only theoretical.  Much of the discussion during this webinar focused on comparisons of Falcon 9, Falcon Heavy, SLS, and the Liberty Launch Vehicle. We also used a Falcon 1e as a baseline for comparison.  Dr. Jurist and the callers planned missions to LEO and the ISS, the Moon, and Mars.  We also looked at costs of total payloads delivered into LEO as a function of launch vehicle reliability and cost for multiple launches into the same position in LEO. Even with our two hour discussion, we did not get to cover several spreadsheet pages that rough out launch vehicle configurations and costs as a function of payload and total production runs. We will cover more of this material in the upcoming parts of this webinar series through early next year.  Dr. Jurist addressed questions dealing with simultaneous launches and third party depot operations including fuel sales and space tug services.  Some other subjects were also discussed in the webinar including the recent high altitude jump by Felix Baumgartner and combating the spin.  We also talked about the recent statement made by Felix about not spending money on Mars missions in favor of saving the Earth.

Please post your comments & questions on The Space Show blog.  Dr. Jurist and I will respond to your blog posts.  If you want to talk to Dr. Jurist about his spreadsheet and your possible use for it, you can email him at jmjurist@aol.com.

Cislunar Space Development

http://archived.thespaceshow.com/shows/1876-BWB-2012-10-19.mp3

Guests: CLASSROOM:  Dr. Paul Spudis, Dr. Jim Vedda.  Topics:  Cislunar space development and economics.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blogs, http://thespaceshow.wordpress.com and the Classroom blog, http://spaceshowclassroom.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming.

Contact Dr. Livingston for questions about our copyright and trademark policies which we do enforce.  For this Classroom Space Show two hour program, we welcomed Dr. Paul Spudis and Dr. Jim Vedda for a comprehensive discussion on the importance of undertaking Cislunar space development as a major focus of U.S. space policy.  Our program was in two equal segments but since our topics crossed segments, our summary will reflect the entire program, not each segment.  Also, at the end of this summary, I have listed several relevant URLs for cislunar space development and our guests.  If you want more information on the subject, I suggest you visit the recommended websites and blogs.  Our guests described cislunar space for us and did an excellent job in letting us know why it is important to focus on a cislunar space development program.  In the process of addressing this very important issue, we talked about policy, the railroad model, the need for space infrastructure, insitu resource development and understanding, lunar water, lunar ice, lunar polar robotic exploration, the need to learn to live and behave in space, and much more.  Listeners called and asked email questions that drew out both our panel members so that our discussion was sufficiently thorough.  Side issues were discussed such as budget cuts, tight budgets, how to do cislunar space in a belt tightening environment, small businesses and contractors, even sequestration.  Our guests were very clear as to why cislunar development was much more preferable than “space stunt accomplishment” types of programs and projects.  Our guests presented a good case in letting us know why cislunar development is preferable over a humans to Mars mission at this time. Another issue brought up by a listener was to ask about “Plan B” if for some reason there was no water or there was insufficient water/ice on the Moon.  Dr. Spudis explained why that was not likely but both panel members talked about why cislunar development was important to even without sufficient water/ice resources on the Moon.
