We welcomed Bob back to the show for the last time in 2015.  During the first segment of the 2 hour program, Bob started our by remembering Apollo 8’s flight around the Moon on Christmas Eve, plus he talked about his new edition Kindle version of his classic book, “Genesis: The Story of Apollo 8.”  Bob spent some time retelling the full Apollo 8 story, how it came about that Frank Borman and crew decided to read the first twelve chapters of Genesis for the huge broadcast that was heard around the world, then he contrasted the astronaut’s freedom to choose their own words to what he expected would prevail today.  What do you think?  Post your comments about this on the blog.  After the Apollo 8 story, we discussed the return to flight by both Orbital ATK and SpaceX.  Bob shared his perspectives about this plus his rational for NASA wanting to work with possibly four companies for commercial spaceflight for cargo to the ISS.  Caller Richard Easton was next to talk about Apollo 8, then he wanted to know Bob’s thoughts on the need to first go to the Moon before going to Mars. This turned into a mini-discussion that included reference to the NASA Roadmap to Mars, the Elon Musk plans to go to Mars and why, along with giant rockets, with Bob commenting on why giant rockets would be inefficient and not necessary. His call consumed the balance of the first segment.

 

In the second segment,  I read an email from Doug asking about ISS plans and the possible impact on a Bigelow space station.  Jody emailed in a question asking about the space positions for the presidential candidates for both parties.  Bob limited his comments to Mrs. Clinton, Mr. Trump, Sen. Rubio, and Senator Cruz.  In the process of talking about their positions, he went after big government programs such as SLS and Orion.  Jack sent in a question asking about recent XCOR changes in management.  Bob had much to say about this, though it was more about the company in general and the industry.  He did take the opportunity to applaud Blue Origin.  Doug called the show and his call consumed almost all of the balance of the second segment.  Bob and Doug had a grand old time planning missions without heavy lift rockets using multiple launches of the F9, ion & solar propulsion.  I refrained from entering their discussion and let the two continue until we needed to move on near the end of the show.  Bob was again critical of SpaceX wanting to build giant heavy rockets for going to Mars saying FH was large enough and efficient.  The assumptions the two made were in my opinion very generous but at least we know where Doug and Bob stand on these issues.  If you have comments about their discussion make sure you post your comments on the blog.

We welcomed Rand Simberg back to the show to discuss his recent successful Kickstarter campaign, “Clearing The Roadblock To Mars.” Check it out at www.kickstarter.com/projects/1960236542/clearing-the-roadblock-to-mars. During the first segment of our 1 hour 32 minute show, Rand introduced us to the purpose of this campaign which was to show how much better and wiser NASA could use the funds now being spent on SLS. Or as Rand said throughout our discussion, to get more bang for the buck. Of course this assumes NASA would use the savings wisely. In this segment, Rand spent considerable time addressing the lack of SLS missions, the types of missions SLS might be used for but so far no such SLS missions have been settled on, plus he talked about having more efficiency by using smaller rockets, more launches and fuel depots. He also said we were not serious about space as evidence by the SLS program. Several listeners asked him about the trades between heavy lift and a smaller rocket, the risks involved, costs and more as this is a common debate topic in the industry. Rand said the debate would eventually be settled by market forces. I added in that the characteristics and performance of the rockets being used to settle the heavy lift or not question will also factor into any conclusions reached on this subject. Rand then talked about the Aerojet Rocketdyne announcement that they wanted to acquire ULA for $2 billion. This led to an additional discussion about the Atlas rocket, Russian rocket engines, Vulcan, and Blue Origin. He also answered specific questions about his Kickstarter project which he said was to show how much more could be done wit h the SLS money rather than spending it on SLS. In response to listener questions wanting him to compare SLS to Falcon Heavy, he said about three Falcon Heavy launches would equal one SLS launch. He advocated SpaceX do an Apollo 8 type of flight with the Falcon and Dragon but then said it probably would not happen because of their relationship with NASA.

As we started the second segment, Dr. Doug called from S. California to inquire about the technical capability of SLS and Falcon Heavy plus the ULA Vulcan medium to heavy lift rocket. In addition, Rand discussed the reusable Vulcan concept as compared to the SpaceX concept of landing on a barge. Rand was asked about the need for heavy lift for Mars. He made it clear he was not interested in Mars per se, instead, he wanted to lower the cost of space access to make it possible for anyone to go anywhere in the solar system, including Mars. Rand said over and over again that he was destination agnostic. He continued getting questions about heavy life vs. many smaller rocket launches. Rand said things like it was too risky to put all your eggs in one basket, i.e. the one big heavy lift launcher. Several listeners wanted to know the best path to try to influence the direction of space policy. Rand focused on congress and suggested visiting local congressional offices. Other listeners asked him about a possible increase in the NASA budget. He said money was not the issue for NASA. The issue was using the money wisely to do more with it than we are doing now. He repeated many times during the program that we were not going to have a replay of the Apollo program. Don’t miss his comments on this as they are scattered throughout our discussion. Near the end of the show, Rand was asked about the 2016 elections and space policy, rocket staging, even SSTO rocketry. When offering us concluding comments, he repeated we would not be repeating Apollo, that it was never that popular and much about it is a myth. Don’t miss what he had to say about the Apollo program and missions.

After a long absence, we welcomed Dr. Jeff Bell back to the show for a nearly 2.5 hour critique of NewSpace as well as traditional aerospace. In the first segment of our very long program, Dr. Bell started off talking about the SpaceShip2 accident and the NTSB report, then he went into a lengthy discussion about hybrid rocket motors. Later in the segment, he turned his attention to first stage recovery efforts regarding the Falcon 9, testing procedures, ground testing, and more. Jeff had much to say about these & other topics which covered the first hour of the program.

 

In the second longer segment, Jeff from Tucson was the first caller. He started off by talking about a book Dr. Bell had recommended on a previous Space Show program “Ignition.” Per our discussion, it is a free download book at http://web.gccaz.edu/~wkehowsk/ignition.pdf. Other topics in this segment included the Ranger Program, lots on cubesats as Dr. Bell questioned the usefulness of very small satellites. Later on, Dr. Bell recommended another book, this one by George Sutton, “History of Liquid Propellant Rocket Engines.” Another topic Jeff seemed to go after was what he referred to as, “NewSpace Patent Wars. He particularly zeroed in on the Blue Origin-Space X patent dispute over landing first stage rockets on a barge to achieve reusable first stages. Jeff then told how patent wars had been used over the years and he cited many different examples, including going back to Robert Goddard. Later in the segment, he suggested many of these influences were a result of the influence Silicon Valley has had on the space industry, particularly NewSpace. He then talked about booster recovery in general. Doug sent in a note asking Jeff which he preferred, the SpaceX’s propulsive recovery or ULA’s airborne recovery of just the engines. Before the segment ended, Jeff addressed Antares and the use of Russian rocket motors. More was said about cubesats, then Jeff took off on government subsidized programs. His last topic or target one might say was suborbital tourism. Don’t miss what he had to say about this part of the industry.

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

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

We welcomed Henry Vanderbilt back to the program to tell us about the upcoming Space Access Society Conference to be held in Phoenix, Arizona from April 30-May 2, 2015. For information, speakers, and program agenda, see www.space-access.org. During the first segment of our 91 minute program, Henry talked about the logistics of the conference to be held at the Radisson Hotel North in Phoenix. You can register for the conference and the hotel online. Henry then highlighted many of the sessions and speakers for this year’s event. See the Space Access website, www.space-access.org. I asked him what talk or event excited him the most and he said they all excited him. He then focused on a few main speakers including Dave Masten, Jeff Greason and the COTS 2 Return to the Moon track that Dr. Doug Plata will be chairing. Details for this special track within the overall Space Access track are on the Space Access Society website. Henry highlighted the special track with Doug and his track participants, then he focused on the Town Hall Program designed to solicit new and fresh ideas for cheap access to space and space development. Before the segment ended, Charles Pooley called and we talked about New Horizons and fast, high energy deep space issues and advanced propulsion as a result of Marshal’s phone call.

In the second segment, Doug called to talk about his track but also about the superb networking opportunities at Space Access. Doug, picking up on a first segment listener email question, said that the conference was not a space settlement conference but that with affordable space access, space settlement gets much closer to reality. Henry then spoke about Henry Spencer returning to talk and along with Doug, mentioned reusability and lunar landers. Henry will talk about rocket safety, reusability and more. Advanced propulsion technology was discussed when Ft. Worth John called us, then Henry talked about EML2, more conference speakers plus the need for fuel depots. At the end, he said that the Space Access Conference supports their political activism which Henry is really good at doing during the year on very important and key issues. He cited an example from last year. Henry also said there was still room for more speakers but you need to quickly contact him to see if your topic can work for the event. You can email Henry at space.access@space-access.org.

We welcomed Marcia Smith back to the program to discuss the proposed NASA FY 16 budget and process, sequestration, specific NASA projects and more.  During our one segment 69 minute discussion, Ms. Smith started out by stating that the proposed 2016 FY NASA budget was bigger than the 2015 NASA budget by about $500 million!  Ms. Smith continued saying the trend was upward with continued strong support for SLS, Orion, and even Europa.  Also, NASA remains largely bipartisan in its congressional support.  I asked our guest about the coming sequestration for 2016-2021 and here, uncertainty prevails.  We also learned that there would be more flexibility for targeted sequestration cuts than there were the first time.  Sequestration has a focus towards two categories, security and non-security projects and expenditures.  Bob in Tucson sent in our first email to inquire about a possible “war” within the NASA planetary science and human spaceflight directorates.  A question came in regarding congressional motivators with a focus on SLS motivators.  Among the SLS motivators mentioned by our guest were national prestige, global leadership, preserving and growing our industrial base, and keeping people employed.  Jerry emailed in asking about NASA educational outreach and support in the proposed FY 16 budget.  Our first caller was Michael Listner who wanted to expand on earlier comments about the private sector and NASA, specifically government programs.  Marcia and Michael had an interesting discussion focusing on these issues.  Both cited examples including ULA, the EELV program, and the concept of “skin in the game plus the opportunity for a private sector company to fail and maybe needing a government bailout if all our eggs were in that one private sector basket. The new Lockheed Jupiter commercial cargo space tug program was mentioned and Michael said it might be useful for removal of some space debris.  The subject of building LEO infrastructure came up multiple times during our discussion, especially the issue of who or what entity would pay for its development. Government or the private sector?  BJohn asked Marcia email questions about reusability thus providing NASA with more “bang for the buck” so to speak.  I asked Marcia several questions about the discretionary part of our budget, we talked more about the Europa mission and the best way to influence congressional space policy makers.  Our guest had some very interesting things to say about this so don’t miss the discussion.  Near the end of the program, I asked if there was any serious effort to move to ten year funding for space and other very long projects given the likelihood of a program not lasting ten years due to congressional changes and program cuts.  Marcia did mention that the shuttle and ISS programs survived so it was possible for a program to last a long time. She also did not think there would be ten year funding as congress would not give up its continue oversight responsibilities for such a long term obligation.  Peter in San Diego asked about the 2016 elections and if we were likely to see a radical shift in space policy.  Donald in Los Angeles asked if the one party congress would get the budget done or if we were likely to see a CR at the end of September.  BJohn sent in another email asking about possible congressional motivators to be even more supportive of space than they have been given their $500 million budget increase.  Beverly asked Marcia about international cooperation with space projects.  Marcia said she was a strong supporter of international cooperation.  She also provided us with a few of her excellent reasons for supporting international cooperation.  Before the program ended, we came back to the issue of LEO infrastructure and cislunar development.  Given the private sector’s reluctance to invest in these areas so far, a natural conclusion would be that the private or commercial markets are not yet developed.

Please post your comments on TSS blog above.  Visit Marcia’s site, www.spacepolicyonline.com for the latest in space new and policy developments.  You can reach Ms. Smith through her website or me.

Welcome to our Audition and Co-host program.  During the first segment of our nearly 2 hour program, we did not get any audition calls from people contacting me to put themselves on The Space Show as a guest.  Toward the end of the program I took a call from Andrew regarding his being a co-host and one from Tim with an excellent suggestion for how to be on the program.  More about those calls when we get to the second segment.  For the first segment, Marshall called and talked about three sci-fi books he is writing plus I asked about his daughter who won a Space Show contest years ago and she got a tour of Loral and their satellite mfg. business.  Pooley called and talked about SpaceX, then he talked about the next several books being planned in the Microlaunchers series.

 

In the second segment, John in Ft. Worth called to talk about seeing the video on rocket reusability with Tori Bruno at Stanford. Mr. Bruno is the ULA CEO.  The better link to use when seeing this hour long video is http://youtu.be/iVFz67WCPIw.  John and I strongly recommend it.  Doug began emailing questions to John about depots and his previous calculations regarding the Falcon Heavy.  John admitted to an error in his previous analysis which he discussed that with Doug who was communicating via email.  Our next caller was Tim in Huntsville who suggested blogtalker.com for people who contact me wanting to be on the show.  Clearly such people do not follow my suggestion which is to call an Open Lines show or call when I do the auditions show but with blogtalker.com, they can actually make a short demo talk on their subject or topic for TSS and send me the URL.  Based on how well they do, the interest in the topic plus other factors, that would help me decide if a self-invited guest should be on the show.  Andrew was our last caller and he talked about himself being a co-host for topics dealing with astronomy, telescopes, engineering, machine tools, and more.  Doug communicated with Andrew by email to discuss the role of machining in the setting of an initial base (Moon or Mars) when in situ metals are accessed.  What all could be made?  I am working on this show with Andrew.

 

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

We welcomed Dr. Bryn Laubscher back to the program for our 2 hour 22 minute discussion about carbon nanotubes and the Space Elevator.  During our first segment, Dr. Laubscher talked about carbon nanotubes, the manufacturing process, how to move the process and technology forward, end uses for the product, possible timelines for advancement and the current day use of Chemical Vapor Deposition (CVD) in the process.  Bryan talked about the need to find a better process for making carbon nanotubes than CVD.  Later is this segment, Dr. Laubscher was asked about the potential relationship to space other than with the space elevator.  This was an interesting discussion , don’t miss it.

In our second segment, Bryan talked about how hard and challenging the space elevator was and later in the segment, due to a call from Pooley, we went through many of the top challenges faced by the elevator with a status report on each one.  As this segment was opening, I did ask Bryan for a time line for space elevator advancement.  Our guest suggested that at some point, there would be significant demand for the elevator.  Next, we talked about the upcoming International Space Elevator 2014 Conference to be held at the Museum of Flight in Seattle, August 22-24, 2014.  For conference info, visit http://www.spaceelevatorconference.org. John from Ft. Worth called to talk about materials, composites and much more. We also talked about the strength needed for the elevator ribbon and John asked about SSTO.  Blaze emailed us about nuclear waste and Bryan had an interesting take on it. This was another valuable discussion, don’t miss it.  Dr. Laubscher talked about ribbon length, characteristics, strength needed, and its location in space, plus the counter weights it would need.  Adrian emailed several questions to us about the ribbon breaking and related issues.  He also asked our guest radiation issues.  Doug emailed about ways to climb up and down the ribbon.  Some of the other issues that came up were wind, lightening, ribbon oscillation, space debris, policy & regulatory issues.  As our program was ending, Bryan offered us words of wisdom and said his company website was http://www.odysseustech.com.  In addition, Dr. Peter Swan emailed us about his paper on the elevator which you can download and read at  http://www.virginiaedition.com/media/spaceelevators.pdf.

This will help me bring better programming to the audience.  We welcomed back Clay Mowry to the program to discuss Arianespace and the launcher industry.  During the first segment of our 90 minute discussion, we took on the subject of the upcoming last EASA ATV 5 flight to the ISS.  Mr. Mowry explained why this program to the ISS was ending and that after this last flight, there would be only one vehicle capable of boosting the ISS.  He talked about U.S. priorities in building up cargo capability to the ISS without boost capability over commercial crew.  We also talked about the life expectancy of the ISS amid the current controversies with Russia and the US.  I asked Clay for a brief history of the launcher Ariane 5 and we learned that they now have 59 successful launches for this rocket.  Our guest talked about Ariane 5 performance capabilities plus upgrades that are in progress for an Ariane 5 ME.  We talked about launch price/cost and its relationship to how customers determine what launcher to use.  As he said the last time he was on the show, customers need launcher reliability and the ability to launch on schedule.  Launch costs are an overall factor of the total risk of the launcher, the value of the satellite, opportunity costs, infrastructure costs, and more.  This is a very informative discussion and it continued into the second segment.  Our guest also said that human spaceflight poses different issues than launching telecommunications satellites and is more sensitive to launch costs.  Listeners asked about government subsidies to Arianespace and their not turning a profit despite their commercial success. This opened up a discussion about all forms of government subsidies, including the methods used in the U.S. to subsidize and support our launcher industry.  We talked about the planned new Ariane 6 rocket and its differences with Ariane 5.  We also talked about rocket development time lines.  Rocket reusability came up and this proved to be a great discussion topic that continued into the second segment.  Clay provided us with very important perspectives regarding reusability.  Dr. Jurist called to go deeper into the issue of launch pricing, insurance, and related items. Don’t miss it.  Clay referenced several studies on this subject including the Futron NASA Ascent Study which examined launch costs among other things.  Our guest talked about ways the satellite industry is working to reduce launch costs by making satellites more powerful and lighter.  They are also starting to use ion propulsion which can cut up to 40% of the mass of the satellite which makes launches lower in cost. With more efficient satellites, longer life spans, and other advancements, its possible to see launch cost improvements up to around 20%.

In the second segment, I asked Clay what it would take to human rate the Ariane 5.  After he explained the requirements, he said their company focus was on satellites.  He mentioned Liberty Rocket, then John from Ft. Worth called in to talk about costs, depots, reusability, & just how many flights can a reusable rocket make, plus insurance risk evaluation for reusability.  Clay talked about reusability economics and risks in depth in this segment, explaining the variables and unknowns. This is an important discussion so don’t miss it.  Later by email, Jim asked about increased satellite efficiency & advanced capabilities lowering the launch rate.  Clay did not think so due to content advances and increases that offset the satellite advancements.  Again, another important discussion topic. In fact, we spent most of the balance of the program on this subject.  In concluding, Clay said the business was even more exciting today than when he joined the industry and later Arianespace.  The final listener comment asked about the launchers being the unsung heroes of our modern society.  Clay summarized that reusability had many market, technical, & economic unknowns, that HSF probably was better suited for it than satellites, & that commercial communication satellite customers need reliability & on time launches as part of their business models.

We welcomed Dr. Ajay Kothari to the show to discuss first stage  and full rocket reusability.  During the first segment of our 1 hour 44 minute discussion, Dr. Kothari opened with references to his April 14, 2014 Space Review article, “Robust and Reusable.”  I suggest you read this article and have it handy as a reference as you listen, http://thespacereview.com/article/2490/1.  Dr. Kothari explained  his model and analysis process to evaluate the costs and economics for rocket reusability options.  Our guest goes through his models and scenarios for us, notes that they are only for TSTO rockets (2 stage to orbit), plus he identifies his analysis and software tools.  His analysis led him to understanding the importance of the First Unit Production Cost (FUPC) and how this is a killer without a high rocket launch rate.  Dr. Kothari then talked about the possibilities for space tourism.  As you will hear, he thinks much more of orbital tourism over suborbital tourism which is understandable when you see his costing, price points, percentage of net income being spent on the flight, & a few other parameters.  When asked if he thought orbital space tourism would be the economic driver for rocket reusability, he said he thought it had the potential to be a significant contributor to it.  Listener Paul asked him about the reusability penalty due to added mass for a reusable rocket.  Ajay said they addressed that in their model and suggested a reusable rocket capable of the same payload and destination as an expendable would need to be 2-4 times the size of the expendable!  John from Ft. Worth was a caller with many questions but near the end of this segment, he asked for Ajay’s thoughts on the SpaceX reusable system and process.  Our guest thought highly of the SpaceX effort, process, and concept.  We also talked about both flyback and boostback options.

In our second segment, Dr. Jurist called in and addressed efficiencies in the learning curve which benefit expendables over reusables though our guest was quick to point out that after decades we still cannot build on these learning curve efficiencies to move further out with expendables in technology and cost reduction.  Dr. Kothari and John spoke about the flight rate b/e point which is largely unknown.  I then asked our guest about full rocket reusability and his ideas for a hypersonic second stage to orbit and back.  Dr. Kothari spent time with us during the balance of our program discussing his concept.  We even discussed point to point transportation as a result of this model and he suggested the innovative idea of combining limited orbital space tourism with Point to Point to make it more acceptable. Don’t miss his explanation of this idea.  Tim called in wanting to know about landing large payloads on Mars , possibly using inflatables or magnetic fields generated by a hypersonic in the Martian atmosphere. Doug was our last caller asking about rarefied gas flow & possibly returning to Earth from the Moon with a lighter weight heat shield, even what bouncing off the Earth’s atmosphere meant for Earth capture of the incoming spacecraft.  Our guest talked with him about this along with steady flow or steady heat conduction.  To conclude our discussion, Ajay summarized his models that closed the business case for orbital space tourism, including the one model that could not close.  Note the parameters he talks about for each model.  For more information, check out Dr. Kothari’s website for Astrox Corporation (www.astrox.com).
