This will help me bring better programming to the audience.  Welcome to our 1 hour 55 minute Open Lines discussion.

 

I started off the first segment with suggested show discussion topics, then John from Ft. Worth was our first caller to discuss the Don Nelson recent show and his idea for a fleet of modern private and commercial space shuttle freighters.  John had some interesting things to say about this idea as well as potential market issues given Don wants his freighters to be privately built and operated.  During the call with John, we talked about the possibility of the Federal Reserve raising interest rates and what that may mean for the space industry as well as other segments of our economy.  Though the NASA part of the budget is small, it is visible and it could be adversely impacted by a rise in interest rates as more money will have to go to paying the interest on our national debt.  Our next caller was Jeff from Tucson.  Jeff pointed out large aerospace industry trends and addressed the recent NASA delay in commercial cargo awards though they told Boeing they were no longer under consideration with the CST100.  Jeff also spoke about other projects with SpaceX, Orbital ATK, ULA and Aerojet Rocketdyne.  He spent a good portion of his discussion time talking about problems facing Aerojet Rocketdyne, possible merger solutions and parts of the business which it may need to let go as compared to pursue and continue developing.

 

In the second segment, Tim called in with questions about Maven and the recent announcement regarding the Martian atmosphere.  Doug was our next caller. Doug is planning a debate at the upcoming ISDC meeting next year on cislunar plans starring himself with his plan and John Strickland with his plan.  Doug talked about the differences between his position and John’s, wanted to our thoughts on adding more people to the debate with their cislunar ideas, then I asked Doug what his expected outcome was for doing this.  Don’t miss what he said about his expectations.  I told him I would be glad to do a Space Show debate with John and him as a “warmup” to the ISDC event.  I hope that happens.  Doug concluded his call saying he still hoped to call The Space Show while riding and trying to eat on the Gravitron at his local theme park while spinning at 24 rpms.  If he manages to this, it should be an interesting call.

Guest: Don Nelson.  Topic:  Development of a fleet of privately operated Commercial Space Shuttle Freighters (CSS Freighter) for commercial space, NASA & Air Force.  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.

We welcomed Don Nelson back to the show for this 90 minute discussion regarding his Commercial Space Shuttle Freighter (CSS Freighter) concept.  During the first segment, Don provided us with an overview of our current launch and human spaceflight situation, he talked about safety and reliability, then he started describing his CSS Freighter Concept.  You can learn more about it at his website, www.spacetran21.org.  He spent time explaining why wings were needed despite the common misconception that they become worthless mass in space.  He said over and over again that if one does the trades, wings come out far better than carrying additional propellant for a vertical landing.  He also said he was a strong proponent of full reusability, not just first stage reusability.  In response to several questions, he said his CSS Freighter was modeled after the shuttle but with new upgrade designs and technology though to save money and reduce development time, the freighters were to be based on existing technology.  He had much to say about the difficulty they had in upgrading space shuttle systems so this time around he said upgrades would be modular and as close to plug and play as possible.  His idea is that the freighters will be built and operated by the private sector.  He suggested the extensive use of composite materials to save on mass and to use reusable Space Shuttle Main Engines (SMEs).  He referenced the Air Force X-37B program, he talked about the advance state of the thermal protection systems (TPS) for this top secret spacecraft suggesting it would be the TPS of choice for the freighters.  Our guest was challenged in both segments regarding other reusability options including the advancement toward success represented by SpaceX and the Falcon 9.  Don said it was first stage only, he was talking about full vehicle reusability and making the case for his approach with wings.  Don’t miss the challenges and the replies. Don also spelled out the advantages of horizontal as compared to vertical vehicle landing regarding reusability.

In the second segment, BJohn asked about the Soviet version of the shuttle, the Buran.  Don mostly talked about lessons learned by their not having a reusable space shuttle main engine (SME).  Don was asked about international vehicle participation in his freighter project. He said not with this Congress and referenced our policy on not talking with China.  Don was also asked for the rational for doing this and he focused on competition.  Make sure you hear this discussion.  He said he was including the Air Force in his plan given the rapid turnaround time for the vehicle (five days).  He explained the Air Force market in detail and is in touch with key Air Force people.  In addition, he has made presentations to members of Congress and their staffs plus key people at NASA.  I asked him how they responded to the concept.  You don’t want to miss what he said about that.  Alex asked an email question about launch pads and NASA having altered or gotten rid of the shuttle launch pads.  Don said launch pads were not an issue, even suggested foreign launch sites, but did say KSC was a prime launch location in the U.S.  Don attacked expendable rockets over and over again in both segments so Ben from Seattle pressed him as to why his reusable freighter would be more reliable than an expendable rocket.  He said each flight of an expendable rocket was a test flight.  Our guest received a questions about suborbital flight evolving to orbital flight, listeners asked about private Bigelow space stations, and one listener wanted his thoughts on the Skylon.  Tim called in and talked about chemical rockets and rocket fuel. He also inquired about scramjets and Big Dumb Boosters.  Doug called in to challenge his reusability comments citing the Falcon 9 to make his case that wings were wasted mass.  Don’t miss this discussion.  When asked if he thought things would change as a result of the coming elections, he suggested that a new congress would likely terminate SLS given our budget & SLS problems.  Don’t miss the balance of his concluding comments.

Please post your comments/questions on TSS blog above.  You can reach Don Nelson through me or his website.

We welcomed back Debra Facktor Lepore to this special one hour one segment program in which we discussed numerous space industry topics.  We started out getting an historical overview of Ball Aerospace, including our learning about some of their new projects with S. Korea and new technologies.  We did a 135  year overview in just a few minutes.  The company really does have a fascinating and most interesting history, including the Ball jars dating back to the 1880s when the company started.  The aerospace part of their history dates back 60 years.  Debra did a good job in summarizing their aerospace history, including moving forward with NewSpace, non profits, cubesats and more.  Listeners asked our guest many email questions including her view of the trends in the space industry, especially among the entrepreneurial segment.  Other topics discussed included disruptive markets and technology, the launch industry, SpaceX, ULA & others, plus the need for viable, productive space  markets.  One market she talked about that was in demand was the market for space data.  Debra had much to say on this subject so don’t miss it.  Debra was asked about human spaceflight which she classified as exploration, discovery, and human nature.  Listener Jack asked Debra about space projects based on the “coolness factor” rather than commercial or national security value.  This proved a very interesting conversation so again, I urge you not to miss it.  Another listener asked about trends toward public only projects, public/private projects, and international cooperative space projects.  Near the end of the show, we had a few listener questions about kids studying engineering but preferring something like an Apple employment to NASA or the space industry because space projects take so long and are often cancelled.   Debra had much to say about this subject plus the potential of space to impact so many other fields.  This prompted an email from a listener who drives part time for Uber.  She pointed out how it was disruptive and based on space technology.  This too was a most interesting discussion that I am sure you will appreciate.  In conclusion, Debra paid her respects to the late George Mueller who recently passed away.   George was a great influence on her life , her career, and the space industry as far back as Apollo.  You can read about Mr. Mueller at http://spacenews.com/george-mueller-apollo-manager-and-kistler-founder-dies.

We welcomed back Anthony Young to discuss his new book, “The Twenty-First Century Commercial Space Imperative.” During the first segment of our 92 minute discussion, Anthony talked about writing the book as part of the Springer Briefs In Space Development Series. He talked about commercial space emerging into a huge venue, then he outlined the format of his book which is for the most part the book’s Table of Contents (check out the book’s Amazon page to read the Table of Contents). You can follow along with us as our guest discusses the major topics and themes based on the Table of Contents. During this segment, I sked Anthony why he thought commercial space was the twenty-first century imperative. Don’t miss his response to my question. Other topics discussed in this segment included entrepreneurism, start-ups, even NASA projects. In chapter 2, Anthony talked about game changers in the industry. Here, he specifically cited SpaceX and Stratolaunch. Later, he included the developing cubesat industry and then in a later chapter, he cited the personal spaceflight industry. Anthony talked about reaching students and addressing the issues surrounding STEM, plus he talked about what was happening with private space outside the United States.

In the second segment, we talked about the upcoming movie, “The Martian” and the fact that it addresses a government mission and has nothing to do with commercial or private space. Anthony cited a recent headline he had seen saying the movie would do nothing to advance commercial space. Returning to the Moon came up next as did international projects which he said were a significant contributor to global peace. Near the end of the segment, a listener asked about the impact of the SpaceShip 2 accident and our guest talked about the NTSB findings. Despite the accident, he said their was significant potential for growth in the personal spaceflight segment of the industry, both for suborbital as well as for orbital flight. Anthony was asked about both the role and risk of government regulation in the emerging commercial space industry. As we were nearing the end of the program, I asked him for his thoughts on what the industry would look like ten years from now. Before our discussion ended, Anthony said he was working on a another book regarding the Apollo lunar samples.

We welcomed back Bob Zimmerman for a two hour discussion plus updates on the space industry, including commercial space and NASA’s planetary science program. Bob started out by saying that the commercial space industry was heating up and getting more competitive, citing two significant stories. First, he mentioned the Blue Origin announcement about opening up a Florida launch site. Next, he addressed the SpaceX news regarding new commercial launch contracts with ARAB SAT and also the Falcon Heavy (FH) with demo launches to start in 2016. Bob spoke for some time on the FH, plus he talked about recent Russian Proton successes with their having said they found a systemic flaw in the Proton system but now that it was repaired, they expected more successful Proton flights. Virgin Galactic was next up for discussion and here Bob said the news was confusing. He spoke to the recent company announcements about Launcher One, then upon my asking, said that SpaceShip 2 seemed to be getting less attention for now. Bob mentioned the possible NASA use of a low cost Dragon capsule, then Jonathan Evans started in asking a series of questions, the first inquiring about what makes more business sense, Blue Origin’s expansion plans in Florida at Kennedy or SpaceX’s expansion plans in south Texas near Brownsville? After responding to Mr. Evans, Bob had much to say about ULA, the proposed Aerojet Rocketdyne buyout bid of ULA, plus the overall competitive nature of ULA in today’s rocket environment. Bob got a question from Jim who wanted to know his thoughts on XCOR given what he had said earlier about Virgin Galactic. Bob was not that positive about XCOR, joking that Charles Lurio would probably call in to rebut his comments. This prompted Dr. Charles Lurio to call in to “correct the record” and the mistakes Bob was making regarding XCOR and their progress. When Charles called in, he had much to say to set things straight.

 

In the second segment, our first call was from Dave in the Chicago area. Dave spoke about Blue Origin and ULA deals plus the ACES upper stage. Later, Bob went after the SLS again, mostly on its costs being too high. John from Ft. Worth called and the two of them had an interesting exchange on several related topics. Bob next mentioned the Rosetta mission and the Philae Lander, then he switched to the planetary science missions and programs. Bob had much to say that was positive on these missions including Cassini, New Horizons, and Curiosity. Later, Jane asked when space policy would enter the 2016 presidential race. Bob did not think it would enter the race, plus he did not want it to become a campaign issue. Listen to his comments and see if you agree with him. Tim called and mentioned that not everyone believes that SLS is bad as Bob had been expressing all night. Bob talked about SLS and science missions, the Decadal Survey, and its high operating and launch costs which hurts planetary scientists. As our program was drawing to a close, I asked Bob about the future of the ISS, Arianespace & what to look out for regarding private/commercial space.

Guest: Rand Simberg. Topics: The Roadblock to Mars and Rand’s recent Kickstarter campaign success.

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.

Please post your comments/questions on TSS blog above. Rand can be reached through me or his blog, www.Transterrestrial.com.

We welcomed Dr. Pat Patterson back to the program to discuss the upcoming 2015 SmallSat Conference to be held in Logan, UT from August 8-13. During our one segment 60 minute discussion, Dr. Patterson not only provided us with the history of the SmallSat conference over nearly three decades, but we focused on many of the highlights for this year’s event. You can follow along with us at the conference website, www.smallsat.org. In addition to talking about the keynote speaker, the CubeSat workshop, student completion, ride sharing, exhibitors, and more, we also talked conference logistics for registration and hotels in and near Logan. Dr. Patterson talked about the social events, networking, and the side programs offered this year. Highlights of the social events take place Tuesday evening with the parties by Orbital ATK and then by SpaceX & Space Services. Toward the end of the discussion, Pat reviewed smallsat industry stats over the past four years documenting the growth and changes within the industry, plus future smallsat plans which if they actually happened, the launch capacity for small satellites would have to significantly improve and expand. Still, the growth stats are reflective of the exciting progress in this segment of the space industry. If you are able to attend SmallSat this year, let me know and please give us reports about it on future Space Show programs.

 

Post your comments/questions on The Space Show blog above. You can reach Dr. Patterson through me at drspace@thespaceshow.com. The SmallSat Conference support staff can be contacted through the SmallSat website should you need their assistance.

We welcomed Dr. Charles Limoli to the program for this 90 minute discussion on space radiation and astronauts, especially flying in deep space, going to Mars or back to the Moon, evening residing on the Moon or Mars. You can read his paper which has been uploaded to The Space Show blog for this program. During the first segment, Dr. Limoli outlined the basics of his research. Before going deeper into the topic, I asked him several questions about the use of rodents and mice for the experiments, the possible use of other animals, the constraints and limitations of radiation simulation experiments, plus how these radiation experiments and doses differ from humans getting radiation treatment for cancer or other medical problems. We had quite the discussion on rodent brains compared to human brains, animal experiments in general, plus the protocols used in his experiments which were all carried out at Brookhaven. By the way, Dr. Limoli is a space advocate, he has received NASA funding for years, and he and his team have a great interest in radiation issues for human spaceflight. Dr. Limoli then took time to tell us how the experiments were conducted. Some of the discussion is technical so I suggest you read his paper which has been placed on TSS blog. Dr. Limoli went into significant detail to tell us how they conducted the experiments, applied the low dose radiation to the subjects, and how they evaluated the results. Don’t miss his description and analysis of the experiments. He said the changes were subtle measured 6-8 weeks out but he also said future papers may show that the cognitive changes continued to happen over a much longer period of time. In response to one of my questions, he said there was no sign of recovery. The primary changes that were observed and reported in the paper had to do with cognitive impairment which we discussed in detail throughout this program. I asked our guest about age, gender, race, and cultural differences. I also asked if NASA was now doing or might do in the future some genetic screening to find those best suited for a high radiation environment. Space settlement risks were talked about as was childbirth and pregnancy. Dr. Doug from S. California called to talk about GCR shielding. He wanted to inquire about using the stuff on the mission, food, water, supplies, etc. for shielding. He suggested the strategic placement of the stuff to maximize shielding. Dr. Limoli did say this was all factored in but that GCRs are non-directional so they come in from everywhere so such “stuff” shielding would only be partially helpful in protecting against radiation. For now, it would have to remain an unanswered question pending getting more research data. In this discussion, Dr. Limoli did explain the components of GCR and what they do to the body and the brain’s cognitive ability.

In the second segment, we took listener questions including several from our friend Dr. Logan. One such question wanted to focus on how deep you would need to go into the Martian surface to equal the protection of Earth’s radiation shielding. Our guest was not sure of the actual calculation but estimated 4-5 meters. Tim in Boston sent in a note quoting what Dr. Zubrin said about Dr. Limoli’s research project per his critique of the paper published in The Space Review May 11, 2015. Dr. Limoli said that what Dr. Zubrin was saying was wrong regarding the details of the experiment. It was a very interesting discussion so don’t miss it. Rhonda wanted to know what Dr. Limoli would say to Elon Musk were he charged with consulting for Elon for his Mars plan and desired mission. Don’t miss what he said he would tell Elon. Later in the segment, I asked our guest to connect the dots with radiation issues and the other human factors medical conditions. This too proved to be an interesting discussion so don’t miss this one either. Charles was asked to talk in more detail about the observed cognitive changes and the actual tests used to reach their conclusions. In his closing remarks, he stressed how important continued research was and strongly urged listeners to support science research, write our congressmen and women, lobby for and advocate more research as it is the research that will give us more information to mitigate and resolve our spaceflight challenges.

We welcomed Jim Muncy back to the program to discuss current space policy and budget issues before the U.S. Congress, company updates, and much more.  During the first segment of our 1 hour 50 minute discussion, Jim provided us with the groundwork for most of our discussion by going back to the Commercial Space Launch Act of 1984, then the update to it known as the Commercial Space Launch Amendments Act of 2004.  He talked about both the House and Senate versions of the NASA and space budget bills and some of the differences between the two bills.  One difference which he explained in detail early in the second segment had to do with the learning period which is important for the developing industry.  Another difference between the two revolved around extending the ISS commitment to 2024 plus issues relating to BLEO space.  When asked if he thought the final bill would be signed or vetoed by the president, he said it was nonpartisan and he did not see problems getting it signed into law.  Listeners asked about funding SLS.  Much was said about SLS in both segments but one listener asked Jim why so many supported SLS given its shortcomings.  Jim explained the mindset of many SLS supporters in congress. As you will hear, SLS is hardly a black or white issue.  This discussion led to a related discussion on developing a new rocket engine, the issues involved, the competitors, methane versus other fuel, and more.  In particular, he used Alabama Congressman Mike Rogers as an example supporting is analysis of the situation.  Jim was asked about the impact of the Falcon 9 failure which led him to address the need for multiple launchers and competition.  Later, Alex asked him about his areas of concern regarding the pending budget legislation.  He talked about sequestration, spending caps, delays, and the problem with operating on a CR which is likely.  This is a lengthy but important discussion so don’t miss it.  Before the segment ended, Jim was asked about the lunar lander.  Jim then talked about the Flexible Path, Google Lunar XPrize, cislunar space development and Mars.  Jim advocated the need for public private partnerships, then he was asked about international partnerships.

 

In the second segment, we started with an email question from Doug inquiring about the Augustine Commission presenting an option for returning to the Moon with landers developed in a public-private program context.  After Jim’s response, I asked him to refer back to a comment he made in the first segment and to explain what was meant by the learning period.  This was an important discussion so don’t miss it.  As part of his response, he also provided a short overview of the suborbital industry and participants plus the orbital industry.  A good portion of this segment focused on the importance of the learning period.  Our last question of the evening was from Helen.  She asked Jim if it would be beneficial to ask political candidates in the 2016 races space related questions assuming they know nothing about space.  Jim supported the idea but he told us all to make the question broader than just what interests us in the space industry. He gave several examples of this.  What he said made sense to me so I urge all of you who get a chance to question a 2016 candidate, ask your space question the way Jim suggested.
