We welcomed Brent Sherwood back to the show to discuss the rational, potential, and economics for the use of space solar power (SSP). During the first segment of our 1 hour 27 minute discussion, Brent first introduced us to Dr. David MacKay from Cambridge University who in 2009 was appointed Chief Scientific Advisor to the Department of Energy and Climate Change. Brent talked about Dr. MacKay’s book during our discussion, “Sustainable Energy-Without The Hot Air” which is available for free on the internet. You should follow along in the book with Brent’s discussion, especially in the first segment, as our guest referred to pages and visuals frequently. Check it out at http://withouthotair.com. Most of the first segment was spent using information from Professor MacKay’s book to explain the current energy and climate situation on Earth and to justifying moving away from petroleum, eventually to SSP. Brent talked about CO2, energy disruption, the transition to something other than fossil fuels, and how to develop SSP. Dr. MacKay used modeling for the UK which Brent referenced, especially from page 215 with the UK map. Brent then talked economics, again referring to the work by Dr. MacKay suggesting an SSP system costing $1.4 trillion! Spread out over a number of years, that price was not much different from what is spent on several government departments and policies, including NASA at this time. Brent listed several examples of this so don’t miss this discussion. Brent then suggested the least path of disruption would focus on the key which would have to be electricity. This took us to our next topic which addressed how to generate the amount of electricity needed, including his identifying several newer technologies that could lower some industry costs. He talked about some of the main challenges including transportation, storage, transmission, & operations. Later in the segment, Brent delved into the cost per kWh for electricity. Marshal called to talk about key new technologies including advancements in related and applicable photo voltaics and more.

 

In the much shorter second segment, Brent talked about macro engineering projects and huge platforms in GEO space. He said that such SSP GEO platforms would be around 7,000 sq. km. or three times the size of the paved U.S. national highway surface. Brent then addressed why none of this ever happens and he pointed to this not being a purpose of NASA as an example. To counter this, he advocated for a serious demo project, even suggesting the use of the ISS for the demo. Our guest talked about the challenge in attracting private capital to this because it is so futuristic right now. However, private capital has flowed to the futuristic industry of asteroid mining. We both asked why to one and not to the other? The last email question of the day was from Carol who pointed out that government policy to regulate coal and CO2 over 30 years is off point. Instead, government policy should produce a serious demo project that confirms the technology and the potential market, then let the markets and industry self-regulate and invest for the future.

We welcomed back Al Globus to discuss his plan for LEO space settlement about 500 km above the equator to minimize radiation, shielding, and to improve the mass ratios to make settlement easier than in other locations.  During the first segment of our 1 hour 49 minute program, Al put forth his hypothesis that radiation over the equator was very light meaning that any space settlement would need minimal shielding or possibly no shielding.  This vastly improved the economics of developing and resupplying the settlement given its close proximity to Earth and the lower mass needed for the settlement and transportation.  This would be a “free space settlement” meaning it would be in orbit.  During this segment and the entire program, Al explained the radiation issues but you should read his paper on the subject, “Space Settlement the Easy Way.”  You can find this paper at http://space.alglobus.net/presentations/Easy.pdf.  Al spent lots of time explaining the radiation issues and talking about the initial settlements which may not have an economic purpose.  Al did go into the technical side of the radiation issues and his analysis for this location so don’t miss what he had to say about it plus as I suggested above, be sure to read his paper.  Later in the segment, he brought up space tourism and space hotels as a type of initial space settlement but one that would pave the way for actual settlements in LEO.  In the end, Al said that a LEO settlement is an easier way to get started with space settlement but stated many times that even a LEO space settlement above the equator would be challenging.  He did get several listener emails, some of which challenged his radiation analysis and the idea that little or no shielding would be necessary.  Al was also asked about space exploration but he was very clear that he was focused on space settlement.

In the second segment, we talked space policy, the U.S. congress and even the issue of space debris removal.  Marshal called to talk about radiation shelters from solar storms, Alexander wanted to know more about space solar power.  Adrian sent in a series of notes challenging Al and using the December 2004 Magnetar event.  Al was not familiar with it.  I inquired of the listeners to tell us what happened to the ISS during the event.  After the show, I got a follow up note from Adrian regarding the event and the ISS:  “Thanks to the magnetar’s great distance, the super flare posed no threat to humanity or Earth’s biosphere. The International Space Station was on the opposite side of Earth when the flare hit our planet, but even if the astronauts had faced the full fury of the blast, they would have received a radiation dose less than a dental X-ray. An SGR super flare’s pulse of high-energy radiation could seriously damage a planet’s atmosphere only if it occurred within about 6 light-years, according to Adrian L. Melott (University of Kansas)”  See more at:www.skyandtelescope.com/astronomy-news/the-brightest-blast/#sthash.VvmrtqKH.dpuf & www.skyandtelescope.com/astronomy-news/the-brightest-blast. I believe the point Adrian was trying to make was that no shielding even for a LEO settlement above the equator leaves the occupants w/o protection in case of an unexpected radiation related event. To this point, Al spent some time talking about risk and risk taking. Toward the end of the program, Al brought up the subject of space mining, Biosphere 2, and the size of the space station. During the show he also talked about artificial gravity and increased spin rates for people at 4-6 RPMs.

Welcome to our first May 2016 Open Lines program.  During the first segment of our very long 2 hour 26 minute program, I suggested 13 topics for discussion.  While we did manage to discuss most of them, the most popular included remembering Charles Pooley and talking about the EM drive.  Many listeners called in during both segments to remember Charles Pooley.  Also in the first segment, the EM drive came up for discussion with John in Ft. Worth.  He had much to say about the potential of the EM drive, plus he commented on why many traditional scientists say nothing is there, that any results are only on the margin.  I cited a recent article at www.nasaspaceflight.com/2015/04/evaluating-nasas-futuristic-em-drive.

 

In the second segment, we started off with Steve Nixon talking about Charles but it soon evolved to a discussion about space solar power and the upcoming ISDC conference.  In touting SSP, Steve referenced the work by Keith Henson and others, the SunSat Competition, and more.  I was extremely skeptical of his SSP claims which depended on Skylon working and significantly lowering the cost of space access. That claim made me even more skeptical.  I told him Keith was welcome back on the show to discuss his latest SSP analysis, assumptions, and claims so we will see if Keith wants to return after ISDC which is later this month in Toronto.  I recall earlier comments & analysis by Keith which were certainly in the skeptical range from my perspective.  I do hope he returns as we can have a good discussion with lots of listener participation.  Based on listener emails and some phone comments, I was not the only one skeptical about the latest SSP claims.  BJohn emailed us to say that Pooley’s idead were coming into their time, plus he commented on EM drive.  Dr. Dwayne Day called in and somehow we got to talking about high price art auctions and the Picasso that just sold at Christies for $179 million +.  I also referenced the Christies auction last year of James Bond movie items including the original Moonraker Space Shuttle model which sold for $89,000+.  Dwayne then addressed his reason for calling which was a recent Jeff Foust article reporting on the status of the NTSB investigation and report regarding both the Virgin Galactic and Orbital Antares accidents.  Dwayne’s comments on the investigation were interesting so make sure you hear them.  We talked more on the EM drive, then Tim called to refute SSP as well as terrestrial solar power. He also said the EM drive could be used as a doomsday weapon!  Dr. Doug called and said kind things about Charles, then he wanted to talk about home grown space experiments.  He briefly mentioned one he did regarding eating dried foods.  He will have more to say about this on the next Open Lines show at the end of this month.

We welcomed Bruce Pittman back to the show to discuss the upcoming ISDC 2015 Conference to be held in Toronto, Canada from May 20-24, 2015.  During our one hour program, Bruce talked about ISDC events in general, then the Toronto location for this year’s conference and the conference location, the Hyatt Regency Toronto.  ISDC is a multi-track conference with workshops and an excellent exhibit hall.  For more information, registration, hotel bookings, visit the ISDC 2015 website, http://isdc2015.nss.org/wordpress.  From time to time during our discussion, Bruce mentioned a separate event needing separate registration, The Space Innovation Business Summit (http://isdc2015.nss.org/wordpress/the-space-innovation-business-summit).  Bruce also went over the list of the keynote speakers, all of which are listed on the ISDC 2015 website.  In fact, I strongly suggest you open the website and follow along with us during our discussion about the event.  Bruce also said there would be upwards of 300 students present from around the world as a result of the Space Settlement Contest.  Bruce highlighted both India and Romania for their student participation in the contest and ISDC 2015.  Listeners asked many conference questions including networking, Q&A sessions, and inquiring if there was both a propulsion track topic and a human factors track topic.  Toward the end of our discussion we took a call from Doug regarding EML2, depots, fuel, Mars transportation, etc.  If you are planning to attend, remember you need a passport to enter Canada. Reserve early for the hotel, the conference and your transportation.  ISDC is a terrific event. If you attend, I want to hear from you about it on The Space Show.

Welcome to our Open Lines discussion program.  During the first segment of our 2 hour 7 minute program, I started the discussion with a few suggested topics and program announcements.  The only suggested topic that had anything like legs was the 19% budget increase for SLS/Orion in the new FY 15 spending bill just passed by Congress.  BJohn sent in an email asking about a possible Lunar Orbital Station, maybe with Orion, in lieu of the ARM.  Next, Doug called in from S. California to promote the concept of Bio Preserve, backing up Earth’s species.  He talked about the need for this and why and how it might be done.  I suggested he check out the Lifeboat Foundation as they have something of a similar plan though its not identical to what Doug was talking about.  I did ask Doug how such a backup plan would be paid for and like most good ideas, paying for them presents challenges though Doug had decent suggestions.  Brett then called in to talk about his online book, “How To Be A Rocket Scientist.”  Get more information about the book and the ten tips that we talked about by visiting his website, http://www.howtobearocketscientist.com.  He said the book is aimed at the high school audience but he has been hearing from adults and college students who also find the book valuable.  We highlighted a few of his ten tips for discussion.

In the second segment, SLS John called re the NASA budget and said there was plenty of money and the funding increase for SLS/Orion put us on the right path.  John continued to make the case that SLS/Orion is our best chance to avoid being stuck in LEO.  I asked him about commercial space options and he said continuing with SLS/Orion does not prevent the commercial industry from following its own path.  Doug sent in a few emails to John about his comments including one saying that continuing with SLS/Orion blocks the possibility of public/private partnerships.  I challenged Doug’s comment on this because it assumes that monies saved by not having an SLS/Orion program would be used on Doug’s chosen space projects.  In fact Doug did say that we need to better spend tax payer money. While we can all agree with that, the best use of taxpayer money is clearly subjective and would depend on who you were talking with about the use of the money.  Marshall called next to inquire about an update show on space solar power.  I told him I would attempt to get a quality and realistic guest on the program early in the new year.  We then heard from Charles Pooley.  Charles talked about the first year anniversary of his first Microlaunchers book, book two which is in progress and plans for book three.  He also said he was interested in the NASA Challenge dealing with laser communications from space.  Also during the show I went over the final end of the year schedule and the plan to play archived end of the report program with Tom Olson as I did last year leading up to our live program with Tom for end of the year on Dec. 30.  I also pointed out that we would have one more Open Lines program this year on Sunday, Dec. 28.

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

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

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

We welcomed Dr. Don Flournoy to the program to discuss the upcoming SunSat Design Competition (www.nss.org/news/releases/NSS_Release_20131028_SunSat.html).  Information about the SunSat Design Competition, the guidelines, prizes and all the details can be found at http://sunsat.gridlab.ohio.edu/node/7.  During the first segment of our 1 hour 25 minute program, Dr. Flournoy introduced us to the International SunSat Design Competition along with the concept of Space Solar Power (SSP).  We talked about the competition, the role of the NSS and also the SpaceJournal which our guest edits, www.spacejournal.ohio.edu (The Online Journal of Space Communication).  Specifically, Don referenced Issue 17, then later Issue 16.  He talked about the need to do proper story telling in a visual format, the need to have your design be technically doable, and include a business plan.  He described the top prizes of which there would be a few at $10K each.  We went over design contest logistics, due dates, the guidelines which are on the above URL and more.  Don then talked about the fundraising involved by the competition, the need to raise sponsorship dollars, crowd funding, and more.  One listener asked if an entry could focus on the launch problem related to SSP.  Yes, that was acceptable.  We talked about the rectennas and he pointed us to an article about this which was posted on Issue 17.  Randy wanted to know if the policy aspect could be an entry since that would be short on the technical component. Again, yes since policy and legal are clearly part of the solution to implementing SSP.  Demo projects came up, especially in reference to nanosatellites and cubesats. Don told about the presentations that take place at the ISDC meeting in May.  We talked about other countries interested in SSP& their role in the competition.

In the second segment, we started with a call from Seth who is member of Don’s Advisory Board.  Seth had additional information about the competition to share with us, plus he talked about the overall educational value of the design competition and work that Don was doing with his students and the online journal.  Don referenced his work with non-technical students, the need to do visualizations for the project, and the work coming out of the Grid Lab.  Don told us about the course he teaches which focuses on creative visualization for science & technology plus how to use social medial.  Our guest was then asked about the potential impact of a demo project and how that might change the project development timeline.  Near the end of the program, Dr. Flournoy was asked about using the Moon for SSP, then he again went over the requirements for entry, including the need to include a business plan. As we were ending, a listener asked him about outreach efforts to policy makers, Congress, staffers,& others, plus their overall interest in SSP.  He was also asked about his student’s reaction to the competition and the overall idea of SSP.

We welcomed Hu Davis and Bill Ketchum to the program to discuss the need for space infrastructure development, SSP, and a space leadership policy by the United States. In the first segment of our 91 minute program, we talked about the need for space infrastructure development, reusable rockets, and space solar power.  Our guest Hu Davis has a Power Point presentation on SSP that will be uploaded to The Space Show blog summary so don’t forget to check it out on the blog.  I will also upload to the blog Bill Ketchum’s pdf paper,  “What Will America Do In Space Now?”  We discussed the history of various space infrastructure studies and efforts and the same for SSP studies, pointing out how new technologies, engineering methodologies, and sophisticated manufacturing have made many projects cost effective today when that was not the case years ago.  Our guests fielded several questions from listeners about the SSP business case, reusability and the SLS compared to the Falcon Heavy.  Doug asked about the use of in space resources & our guests suggested that for SSP for example, using in space resources could account for 90% SSP components.  Questions were asked about the land cost and the use of rectennas.

In our second segment, we talked about nuclear propulsion and tax/economic subsidies to our current terrestrial energy industry which make it harder to develop SSP.   We talked about the problem and the lack of viability for SLS.  Questions came in regarding on orbit propellant transfer and cryogenic transfer development.  As our program was ending, our guests talked about space education outreach, persuading congressional leaders and the public to support space infrastructure development, SSP , and more.

Please post your comments/questions for our guests on The Space Show blog and I will make sure they know about them.  You can email either of our guests through me at Drspace@thespaceshow.com.

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.)

We welcomed Dr. Henry Hertzfeld back to the show for a fascinating 90 minute discussion regarding commercial space, human spaceflight (HSF), recently announced HSF Mars missions, increasing the launch rate, and more.  During our initial segment, Dr. Hertzfeld addressed my question about lowering launch prices to increase the launch rate.  Dr. Hertzfeld did a classic economic study on this subject several years ago and I asked him if today’s current market and commercial space progress had altered his earlier conclusions.  He said no. Later, I asked if space solar power (SSP) could drive launch rates down.  The short answer was no but don’t miss what he had to say about SSP economics, launches, and debris issues.  Jerry emailed in a question about SpaceX being a commercial company given its receipt of government money.  Henry had much to say about what makes a company commercial or not and if it is even an important issue.  Another listener wanted to know about the deep space commercial ventures announced in 2012 and in 2013.  The listener wanted to know if these were really commercial ventures, if regulations could stop them, and what would happen re the ventures needing property rights or the equivalent.  One of the things our guest reiterated several times during our discussion was the need for stability and predictability for the commercial industry.  Questions came in about benefit sharing and he mentioned the likelihood that some sort of international system would develop on these issues. I asked what constituted an acceptable ROI and the example of controlled ROIs as in the utility industry came up.  Doug wanted to know about rocket reusability and its impact on launch costs.  We also talked about both Mars One and the new Inspiration Mars mission.  As part of this discussion, astronaut rescue and the rescue treaty were discussed.  In the second segment, Doug called to discuss property rights for a NEO as opposed to the Moon, wondering if the Moon might be more valuable.  Doug & Henry talked about our having returned lunar rockets as a model for commercially returning lunar products but Henry suggested there might be a difference in returning something for science as compared to commercial exploitation.  Later, we addressed human spaceflight and its challenges.  The Chinese space program was brought up as was the risk of a space war.  Dr. Hertzfeld was asked about putting 10,000 people on Mars, space migration, species survival, space settlement, and the need to explore as possible drivers for HSF.  My final question pertained to our evolving to a business friendly environment in space.  Simply put, we are not there yet.
