We welcomed Henry Kenyon to the show to discuss the subject of hybrid airships.  Mr. Kenyon wrote an article on this subject in the October issue of Aerospace America, a publication of AIAA. His article is titled “New life for an old hybrid (www.aerospaceamerica.org/Documents/Aerospace%20America%20PDFs%202015/October2015/AA_Oct2015.pdf.  Scroll down until you come to the article of interest).  In the first segment of our 85 minute program, Mr. Kenyon talked about modern airships, some of the differences from older style airships, plus he talked about different kinds of airships such as blimps, tethered vehicles, Dirigibles, Zeppelins and the hybrids, noting their differences from one to another.  Mr. Kenyon then talked about the Lockheed experimental P-791 airship which is discussed at length in his article.  He also has some very good pictures of the P-791 in the article.  He talked about its hover ability, how it works, size, speed and cargo capability.  We also learned that if fully loaded, it actually has to make a short take-off run to get off the ground.  Mr. Kenyon noted the military uses for a modern airship, then we talked about commercial uses but as you will hear, the commercial side of the project seems to still be emerging.  Henry was asked about UAVs as a competitor to airships.  We also talked about the recent Raytheon tethered vehicle that broke away from the tether due to high winds.  Our guest noted that the hybrid airship such as the experimental P-791 did not use a tether or mooring tower.  A listener asked our guest about cybersecurity given it was part of his bio that I read as I as I introduced today’s guest.  We had a short but very interesting discussion on cybersecurity issues which you will not want to miss.  Before the segment ended, we talked about the cargo capacity of the modern hybrid airship, comparing it to a large jet such as a C-130 or 747,  plus cargo transport times, cost overruns, and technical problems still needing to be resolved.

In the second segment, Henry told us the P-791 was on display at Palmdale, Ca.  I changed the subject and asked him based on his expertise and observations again from his bio, what type of programs were most likely to be cut or eliminated by congress.  You don’t want to miss his analysis on this subject.  Returning to airships, he was asked about the gas used for buoyancy.  This led to a listener questions about why helium over other gasses.  Our guest replied by talking about helium, hydrogen, and market concerns for helium as it is in limited supply since it is a naturally occurring element and not manmade.  Several listeners asked him about the commercial potential, include general delivery of Fed Exp or UPS type packages.  He explained the competition airships would face from existing low cost surface transportation options.  Before the show ended, listeners asked him about commercial business projects wanting to use airships for internet and communication platforms.  Adrian emailed in saying weather would destroy any real serious use of airships though our guest disagreed with Adrian.  Henry said with advanced weather radar and the speed of a modern airship, weather issues were not the same as with older airships that did not have radar or good weather forecasting services.  Henry said a modern airship could maneuver around a storm given their speeds and if they were grounded due to weather, much of aviation would probably be grounded as well.  Henry offered salient concluding comments you will want to hear.

We welcomed Paul Szymanski to the show to discuss military space, space warfare, cyber issues and more.  In the first segment of our 1 hour 58 minute discussion, Paul introduced us to the topic and told us how he got his interest in the field. We also talked about military space matters in history and how they impact what is happening in space development today, including commercial space.  He talked about the attitude he saw with the Air Force as well as other parts of the government and mentioned that some of our military space data and information goes over commercial satellites and systems.  He explained why this made such systems legitimate military targets and he talked about the risks associated with carrying military data.  He went over historical incidents regarding satellite kills, disruptions, & tests.  He also spoke to U.S. laser weapon work, our ASAT weapons including the F15 efforts, the role of DARPA, and more.  Paul took many listener emails.  They ranged from weapons and war plans for the Moon and Mars to army programs for troops in space or using space to get to a battlefield destination.  He also spoke to the issue of  space to Earth weapons,.  BJohn inquired about Iran and Paul took several questions about U.S. readiness. On this subject, our guest had much to say. He spoke about other countries including China and Russia, but did address the situation in the Ukraine and at one point in our discussion, suggested there had already been a space war regarding the Ukraine.

In the second segment, Paul fielded additional questions on space junk and this time he talked about hiding weapons in space junk that were really ASAT weapons. A listener wanted to know about the cislunar trade routes and while Paul said that was off in the future, the more current focus would be GEO and LEO.  At one point the GEO-Moon area was referred to as a possible battle ground.  Another listener wanted to know about choke points. He referred us to papers on his website, http://spacecontrol.info.  He said GEO was a chokepoint and so were the GPS satellites.  A listener wanted to know about a possible larger role for the Army and Paul agreed that the Army should have a larger role in space warfare issues.  Don’t miss his explanation.  In response to a question by Gabriel, he talked about the 1970s and CSAT, booster failures in the 80s, and the current Ukraine-Crimea crisis.  While some of the reports he mentioned were regarded as rumors, he did do some dot connecting with regards to the Ukraine and the Russian Glonass GPS disruption plus Proton launch failures.  He explained how he connected the dots.  Tell us what you think on the blog.  Cyberwarfare  was discussed as was the effectiveness of a missile defense system.  Later, we talked about space war rules per his July 22, 2013 presentation, “Space Policy Issues:  Top 40 Rules for Space War.”  Near the end of our discussion, we talked about situational awareness , how to prevent defeat, space war game training, responsive space and more.

We welcomed Michael Belfiore back to the show to discuss a variety of space news and current events items, plus trends in the industry.  During the first segment of our 1 hour 41 minute program, Michael talked about DARPA given his recent book on the agency, then we turned to the recent commercial crew down select NASA announcement naming the Boeing CST100 and SpaceX Dragon as the two companies that NASA will continue supporting for commercial crew.  We spent lots of time talking about Boeing and SpaceX plus everyone was wondering if Sierra Nevada and Dream Chaser would find a way to stay in the game.  The next topic was the Google Lunar X Prize challenge. Michael pointed out that a government had gotten to the Moon fist with a rover, the Chinese, thus the rules of the contest were changed to allow the contest to continue.  Marshall called to talk about the down select process and winners. SLS John called to tell us that he thought Dream Chaser and SpaceX would be the winners.  He and others suggested Boeing was the conservative choice.  He also asked about the news that a Boeing-Bezos deal was in the making for the new American made RD180 engine replacement.  Michael suggested throughout our discussion that the old guard or the traditional aerospace industry and participants were under lots of pressure from NewSpace.

In the second segment, we took a call from Doug who commented on the down select process.  Michael then talked about the Tesla deal for Nevada and their proposed gigafactory for electric car batteries.  We talked about electric cars in general, then Tim called to suggest a conversion kit for conventional autos to turn them into electric cars.  I questioned that from a market perspective.  Michael then introduced space manifesting and we talked about the 3D printer on the way to the ISS.  Michael mentioned Maven which was to be inserted into Mars orbit Sunday evening, 9:37 EDT.  News update:  Maven’s orbital insertion was a big success!  Congrats to NASA and the entire Maven team.  We also talked about Comet Siding Spring,  Suborbital flights came up and we heard Michael express concerns about Virgin Galactic & confidence with the Lynx and XCOR.  He talked about the early spaceflight participants and the risks they would be taking.  Visit his website, http://www.michaelbelfiore.com. You can also subscribe to his email newsletter and join him on social media, all through his website.

We welcomed Michael Belfiore back to the show to discuss his recent XCOR Aerospace article (see www.airspacemag.com/space-exploration/The-Lynxs-Leap-223968551.html).  For more information, visit Michael’s website,  http://michaelbelfiore.com.  During the first segment of our 1 hour 44 minute program, Michael talked extensively about XCOR Aerospace and the Lynx per his above Air and Space Magazine article.  Michael has been a long time follower of XCOR and it shows in this discussion.  We also talked about the other suborbital companies and space tourism in general.  Michael was asked about XCOR’s plans to go orbital from suborbital which was another topic Michael had much to say about.  He said his preference was to fly on a Lynx for the more personal and intimate space experience, including wearing a space suit.  Michael said he was bullish about the overall space tourism industry, he is attracted to the growing small satellite industry but remains partial to human spaceflight.  We talked about SLS which he tends to ignore and discount, SpaceX and Orbital Sciences.  The topic of Cislunar space development came up and while Michael said he was supportive, he is drawn to asteroid economic development.  Before our segment ended, he updated us on the Google Lunar XPrize and I congratulated him for winning the NewSpace Journalism Award this year.

In the second segment, Michael was asked about DARPA which he follows. We talked about Starship 100, the DARPA management style & out of the box operations, the Dec. 20th robotic competition that Michael will attend, plus other important attributes of DARPA.  He mentioned upcoming magazine articles he will be writing for Popular Mechanics and AEON Magazine.  Michael was asked about other national space programs including China’s, Russia’s, and more. Doug called to talk about interstellar DARPA activities, and his cislunar economic ideas.  We also talked about returning to the Moon for settlement.

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm.

Our first interview is with Robert (Bob) Meurer, Director of the ATK Business Development Division in Beltsville, MD.  During this 33 minute segment, we talked about how the small satellite market has changed and evolved since we talked with Bob at last year’s conference, plus we got updates on the DARPA Phoenix project, ViviSat, commercial opportunities and issues, the hot new market for on-orbit satellite servicing and the leadership role of ATK in this rapidly developing industry.  For this interview, Dr. John Jurist was co-host.  We focused on commercial development and related issues such as space tugs, even Moore’s Law as a metric, distributive satellite networks, the need for competitive ROIs, and more.  Bob spent more time with us regarding ViviSat and geo telecommunication two ton satellites.  We also addressed the emerging competition, the impact of sequestration and lots more.   ITAR came up as did the relevance on the ATK business of the Small Sat Conference.

Our next segment featured George Torres, Vice President of Communications for the ATK Aerospace Group in Salt Lake City, UT.  George talked about the announcement for ATK being awarded the ALV first and second stage contracts for the boosters for the Stratolaunch project.  George described the boosters, their proposed capability, and more.  We also talked about the high energy solid rocket propellant used by ATK for this project, then I asked George about the five segment booster from the Aries 1 which was cancelled a few years ago.  The five segment booster is interchangeable with the sections of the four segment booster used by the shuttle and now these boosters are being used for the SLS.  We talked about the upcoming static firing tests for the new SRBs for Stratolaunch and SLS.  George then talked about the ATK work in the field of composites and how they are a leader in the industry, doing the composite work for many other companies.  He described the ATK Aerospace Group which includes two launch groups, two satellite groups, and the composite group.  Before our segment with George ended, we returned to the subject of the five segment booster and SLS, focusing on the previous development motor static tests and the upcoming static firing tests actually being qualification motor tests.  Near the end of the segment, George updated us on the Liberty Launch Vehicle. ATK is now positioning Liberty for the cargo market but this will depend on the market for the capacity Liberty offers.

Please post your comments on The Space Show blog per above. You can email either of our two guests through me.

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, https://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.

Guest:  Jon Goff.   Topics:  The Lunar Patent concept and Altius Space Machines company updates.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, https://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 Jon Goff, President and CEO of Altius Space Machines, back to The Space Show for this 60 minute discussion focusing both on the idea of a lunar patent and Altius company projects and updates. I suggest you read and follow along with these websites and blogs:  http://selenianboondocks.com; http://altius-space.com, and Jon’s blog article about the lunar patent concept http://selenianboondocks.com/2013/01/random-thoughts-columbus-article-link-and-lunar-patents.  For the first part of our hour long discussion with Jon, we focused on the lunar patent idea.  Jon got the idea to write about it on his blog from Mike Mealling’s own blog post on his RocketForge blog, “Lessons in exploration from Columbus and the Spanish Crown” at http://rocketforge.org/2013/01/10/lessons-in-exploration-from-columbus-and-the-spanish-crown.html.  Jon spent time with us going over the history of how and why the Spanish crown put forth the Columbus expedition which he said was all about getting patents along the trade routes.  Jon applied this concept to lunar development explaining how it might work.  He also suggested this might be an end run around the absence of property rights and the terms of the U.N. space treaties.  Listeners asked questions about how a patent might work, would it need to be issued by an international entity to be enforceable, and how could it be enforced.  This brought up the question of benefit sharing and terms & concepts such as those found in the Moon Treaty.  Jon said he was interested in feedback, especially from the space legal community so please share your thoughts on The Space Show blog.  During the balance of our time with Jon, he told us about his company plans, new ideas, SBIRs, and SAA agreements to develop a new breed of robotic arms.  We talked about tools for satellite service and possible ISS free flyers.  Jon told us about their project with Nanoracks, DARPA, and JPL.  He also described MINION which is a project with NASA LArc for an extendable/retractable arm that could operate inside the ISS. You can read about this project on Jon’s Selenian Boondocks blog.  A listener asked him about using Kickstarter for funding new projects and another listener was interested in hearing more about Jon’s plans for Altius in the future.

If you have comments/questions for Jon Goff, please post them on The Space Show blog.  You can reach Jon through the Altius website, his blog, or through me at drspace@thespaceshow.com.

Guest:  Dr. James (Jim) Vedda. Topics:  Dr. Vedda’s new book addressing cislunar development rather than destinations.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, https://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed Dr. Jim Vedda back to the program to discuss his new book, “Becoming Spacefarers: Rescuing America’s Space Program.” If you order the book using this Amazon link, Amazon will make a donation to The Space Show:  www.amazon.com/Becoming-Spacefarers-James-A-Vedda/dp/1477130918/ref=onegiantlea20. Dr. Vedda started our discussion by responding to my question about what he meant by “rescuing America’s space program.”  This opened the way for most of the first segment to lay out the recent history of our space program and how we arrived at where we are today, Sept. 29, 2012.  Issues talked about during this narrative included Obama Space, Constellation, SLS, congressional actions, partisan divides, space vision, goals, timelines, space telescopes, Orion, Earth/Moon libration points as a destination, and much more.  We talked about the purposes of various missions & plans and if the stated purpose was sufficient or not for spending public money on it and carrying it out to completion. We then shifted to the Romney Presidential Campaign Space White Paper (www.scribd.com/doc/106652769/Space-Policy-White-Paper?secret_password=a0i3o1yj25ed5ycop3w). Dr. Vedda mentioned that space policy has not always been bipartisan & he provided examples to support his statement.
    We started the second segment by talking about our being in the training or initial phase of his three stages of space development.  The other two phases include cislunar development followed by space settlement & expansion throughout the solar system.  Dr. Vedda made the case for proximity operations in our space development program plus the need for strong public/private partnerships and when warranted, international cooperation with space projects.  Later in this segment, I asked Jim to outline for us his action plan, just how he would initiate a space development program per what he outlines in the book & discussed with us.  In response to my question, Jim outlined several initial steps that need to be taken to get the ball rolling.  See what you think of them and let us know with your blog comments.  We also talked about the general public, how Jim would make his case were he speaking at a Rotary lunch, and the best way to have a say & impact policy makers.  One of our final topics included the newly proposed bill to do multi-year congressional funding of space projects, make use of a to be created space project oversight panel, and have the Administrator serve a ten year term.  As you will hear, we supported the multi-year funding part of this proposed legislation.
Note below that you will find a special PDF slide presentation supporting Dr. Vedda’s book.  I strongly urge you to follow along with it during our discussion.

Listeners wanted to talk about the New Scientist interview with Elon Musk entitled “I’ll Put Millions of People on Mars, says Elon Musk.”  You can read the full interview on The Mars Society website, www.marssociety.org/home/press/news/illputmillionsofpeopleonmarssayselonmusk.  Callers honed in on the reported development costs for the Mars spaceship ranging from the $2-$5 billion.  Those that called the program thought this was inadequate funding.  At one point I looked up the development costs for the Boeing 787 Dreamliner which so far was estimated at $32 billion.  Since all of us thought a Mars spaceship was more complicated and involved in R&D than a new Boeing jetliner, listeners seemed to be more convinced that the projected costs were too low.  One listener brought up the costs of military projects such as the F22, the JSF, nuclear powered carriers and submarines, etc.  Another listener wanted to know if Space X was planning to open up additional launch sites to those that are publicly known.  In the second longer segment, not only did the military hardware come up for cost comparisons, but John in Atlanta wanted to talk about the Space News Op-Ed by Christopher Kraft (http://spacenews.com/commentaries/111219-nasa-needs-wake-reality.html).  Mr. Kraft wrote about the need to internationalize projects and make use of publicly available international hardware rather than build the SLS.  Tim called in from Huntsville to talk about the Musk interview, the rocket development costs, and using space resources to lower the costs.  He even suggested Elon make use of the QuickLaunch idea to put lox/kerosene in orbit for refueling.  Dr. Jurist called in to talk about the human factors for a Mars mission and that they seem to be understated by the Mars advocates.  Dr. Jurist speculated that it might take 5-10 years just to be able to address most of the human factor issues, not including what might be involved in implementing solutions.  We then talked about Stratolaunch and air launch.  We talked about the small payload capacity of the proposed vehicle and the need for multiple flight depending on the mission and the needed total payload.  Our next topic was yet another Soyuz failure and what this might mean for the ISS if the Soyuz problems are not fixed.  Terry called in again from Corpus Christi to talk about the Falcon 9 & Dragon flight in early February and how the success of the flight might become a driver for more commercial crew funding from the government.  With Dr. Jurist, we also explored the idea of inviting a certain UC Davis aerospace engineering professor to the program to discuss horizontal versus vertical launch and reusability.  I concluded this program with my own wish list for more civility within our space advocacy family and for real leadership with responsibility and accountability to emerge at all levels in Washington, DC, not just for space, but for the future of our nation.  If you have comments or questions, post them on The Space Show blog URL above.
