We welcomed Bill Harwood of CBS Space News back to the show for this 80 minute discussion.  During the first segment, I asked Bill for a bit of his personal history going back to when he first started doing space news with UPI.  Next, I asked him what over the years has impressed him the most regarding space activities.  Don’t miss what he had to say about this as multiple space events were on his list.  In addition, I brought up the Planetary Society success with LightSail, their solar sail demo project.  Bill talked about the mission, what is planned next for a larger, more lasting solar sail project, and the fact that The Planetary Society funded the $4.5 million cost from contributions by Planetary Society donors.  Also in the news was the NASA “flying Saucer” which was really the demo of a new landing system for Mars using a huge (the largest ever) supersonic parachute 100′ across.  Bill went into detail on the mission, even how it got tagged a “flying saucer” which he said was the responsibility of the media.  Listener Robert sent in an email asking for Bill’s position on the Moon-Mars debate.  Bill talked about benefits from both positions but did not share his personal preference as he wanted to stay strictly with reporting the news, not offering an editorial.  That said, his discussion of the debate and the pros and cons of each side was most interesting.  We talked some about planetary missions but honed in on New Horizons and Pluto. Also mentioned was the upcoming Europa Mission, then listener Carolyn asked him what he saw for human spaceflight over the next few years.  Ben wanted to know if the private sector could take us back to the Moon.  Bill had much to say about the emerging commercial industry but in the end suggested that the costs were so high along with very high risks that government would be the one to do it for a long time to come.  Don’t miss what he had to say about both costs and risks.  Russia and their hardware issues came up, then we had quite a discussion on commercial crew, not fully funding it, and continuing to pay the Russians rather than getting the job done with American providers.  John from Ft. Worth gave us a call to talk about the SpaceX subsidies for Falcon 9, wondering if the price of a Falcon 9 launch was the true launch cost or a subsidized cost.  John and Bill had an interesting discussion on this with a few added comments by yours truly.  John also used the time to repeat his position that going to the Moon was essential before going to Mars and that SLS was likely a place holder for labor and technology until we have a different space policy with different space leadership.  Bill talked about variables and lots of unknowns, including wild cards from China and other sources that could end up driving U.S. space policy and progress.

 

In the second segment, we talked about public private partnerships citing SpaceX as a good example of such a partnership.  That said, Bill talked about the need for the commercials to have a destination such as the ISS for their goods and services but that is harder to realize with planetary missions.  He said their needed to be something to do with the means to do it. This brought us to a space infrastructure discussion and the possible role of the government in building and paying for space infrastructure, especially to support industrial growth.  Bill then address risk in much more detail.  This is a discussion you don’t want to miss.  We talked vehicle safety, Virgin Galactic, deep space missions, and much more.  Barbara in Chicago asked Bill about frustrations and how the frustration level has changed over the three plus decades he has been covering space news.  Bill took a few questions about the ISS and the potential closing of it in 2024.  He was asked if we were in a space race with China and did not realize it.  Carl inquired about the Indian space program, then Bill talked some more about the CST-100, the Dragon, remodeling the ISS for Independent Docking Adapters for the two vehicles  and he even responded to a question about Dream Chaser.  More was said about the ISS, plus he told us he met a person at NASA who was in charge of figuring out how to deorbit the ISS which weighs about 900,000 lbs. and moves at 5 miles a second.  This is in advance of a probable 2024 termination date.  In his closing comments, he said the public needed to let Congress know about their support for space.  He also reminded us that space was dangerous, costly, and very risky.  Before the show ended, I asked if he had seen rockets blow up on the pad.  He had and he shared a few stories with us.

We welcomed Joan Horvath and Rich Cameron to the show to discuss their new book, “The New Shop Class: Getting Started with 3D Printing, Arduino and Wearable Tech,” the importance of modern shop class training in our school systems, plus modern technology as a learning tool for students.  During the first segment of our 1 hour 42 minute program, Joan explained why they wrote this book, the problem caused by the absence of shop class in schools around the country and the void their book attempts to fill.  The book is targeted to both parents and teachers to assist them in being comfortable with the “new” shop class as the technology, the instruments & tools, and possibilities are totally different from the stereotype of a shop class from previous years.  Joan talked about their pilot project with the Windward School in Los Angeles (see www.windwardschool.org) including the upcoming two day seminar August 14-15,  Design and Maker Class Colloquium: Hands-on with Arduinos, 3D printing, Wearable tech (for details see www.windwardschool.org/design2015?rc=0).  The book is also appropriate for students starting around the 7th or 8th grade but the Foreword to the book was written by a 13 year old student, Coco, who called the show.  Coco was a most impressive caller who works this technology, has a keen interest in it, and I urge you to pay attention to her phone call.  Coco was with us for most of the first segment.  Additional topics discussed in the first segment included the use of Arduinos, STEM and STEAM, portable 3D printers, program funding, teacher and classroom issues. The portable Bukito 3D printer was discussed in some detail and even Coco told us how relatively easy it was to learn to use it.  A few listeners sent in notes asking about how to get a new type shop class started in the schools their kids attend.  Joan and Rich suggested starting small, work with kits, and use the open source world.  It was also suggested that people attend a local MakerFaire or visit a hacker space though the latter may be challenging for students under 18.  Jackie sent in a note asking about both wearable tech and implanted tech.  Rich had some interesting comments on this topic, don’t miss them.

In the second segment, Joan and Rich talked about actionable things by both parents and teachers.  Joan also talked about how students learn and the problems caused for some students when there is no shop class.  She also said there was some parental push back so don’t miss what she had to say about this.  Randy from Tucson emailed in a question about traditional vocational training including the subjects Joan and Rich were discussing.  Joan made a distinction with trade and vocational tech training and teaching young students in a modern school shop class.  Several questions came up for our guests about teacher acceptability of this type of program. Joan said that for teachers, time is a problem as they have to carve out more time to both learn and teach these subjects.  Also, if the teacher and the class are focused on teaching to the test, its an even bigger problem.  Near the end of our discussion, a listener asked about the software used in 3D printing. Our guests mentioned several programs, including freeware, that an interested listener might want to explore.  Prior to the show ending, our guests talked about their upcoming August colloquium per above and fielded one final question from BJohn regarding limitations.  Our guests suggested that in terms of limitations to the use, application, and results of working with this new technology, one’s imagination would likely be the biggest limiting factor.

We welcomed back Dan Adamo to the show for this 2 hour 36 minute comprehensive discussion regarding HSF to Mars, the Second Mars Affordability and Sustainability Workshop report and much more.  During the first segment of our program, Dan started out by telling us the process used to engage him reviewing said report and writing his critique of it which is on The Space Show blog (https://thespaceshow.wordpress.com). Topics discussed in this segment included the use of Low Latency Telepresence (LLT) as compared to High Latency Telepresence (HLT), the absence of human factors and aerospace medical personnel in attendance and said issues missing from the workshop report.  Dan said the key missing information included radiation as well as microgravity concerns.  Dan then questioned the existence of a compelling rational for humans going to Mars.  This became a recurring discussion topic throughout today’s program.  Space settlement came up & so did a possible space race with China.  The subject of a rescue mission came up but there was a detailed rescue mission discussion near the end of the program in the second segment.  Dan was asked about the minimum crew size to operate an LLT program from Deimos or in orbit around Mars.  Several emails were sent in including one by Dr. Jurist addressing high acceleration upon return from Mars.  Dan then suggested the stepping stone approach, starting with cis-lunar space.  Doug sent in questions about heavy lift versus using already large commercial rockets.  Dan and Doug discussed this, then later in the second segment, Doug asked more questions on this topic.  For now they talked about going to Deimos with a Falcon Heavy.  Dan pointed out the need for many more launches and rendezvous missions as compared to one or two SLS type rocket launch.  He questioned if we can’t afford SLS launches, how do we afford even more launches and rendezvous missions.  Marshal emailed us wanting to know about the possibility of lava tube plans .  BJohn asked this guest about a possible Mars cycler & then we moved to the second segment.

In the second segment, I asked Dan what he thought the impact on space policy might be vis a vis the workshop being discussed on this program.  Don’t miss his reply.  Doug asked a question inquiring if for the same cost it would take to send humans to either Deimos or to the Martian surface, one could send many high-latency rovers to multiple locations far from each other to give the rovers many chances to discover evidence for life in different types of places?  This brought us several exchanges comparing LLT with HLT, heavy lift versus smaller rockets and more.  Doug and Dan has several exchanges during this segment, especially when the topic of rescue missions came up.  Ted in Boston asked about the rational for going to Mars, referenced the recent program with Dr. Zubrin, and the payoff or benefits for a human Mars mission.  Dan had much to say about this so don’t miss it.  John from Ft. Worth called to say we were not yet technically ready for Mars and we should use the stepping stone method and focus in cis-lunar development and exploration.  As an example, Dan & John talked about the need to know the actual gravity RX for humans. Dan said we should have a short arm centrifuge on the ISS helping to figure this out but that there was no policy to do that.  We turned to the topic of rescue and I told listeners what I found out about who pays for rescues when I did some quick and dirty research on this a few weeks ago.  The issue of rescue and how it might happen on a Mars mission or even in cis-lunar space came up with many listener emails including several by Doug putting forth various rescue scenarios.  For the most part, since we have no launch on demand, no rockets, pads or hardware sitting around ready to be used at a moments notice and we have to contend with launch windows, it does not seem feasible that a Mars rescue mission could be implemented, possibly not even a lunar rescue mission.  Doug suggested a scenario where multiple ships left for Mars at the same time and then if one got in trouble, the others could rescue the problem ship.  Dan talked about the physics and mass of what would be needed to do that. You decide if it might be feasible for such a rescue scenario to be implemented. Let us know your thoughts on the blog.  If the rescue party is already on Mars, rescue will be unlikely given the state of the art today.  Michael Listner suggested the absence of a realistic rescue plan may hinder the issuing of a launch license.  In his closing comments, Dan focused on the workshop critique saying that the sponsors would have been better served if participation had been opened up and had including human factors and aerospace medicine professionals.

We welcomed back to the show Greg Meholic to speak about advanced propulsion concepts, rocket reusability, and much more.  During the first segment of our 84 minute program, Mr. Meholic first defined what he meant by the term advanced propulsion.  Given this definition, we moved forward to discuss various concepts, propulsion methods, and propulsion research. During this segment, we talked about several propulsion technologies and Greg said thumbs up or thumbs down to their being advanced propulsion.  When it came to nuclear, Greg classified it as an alternative propulsion method, not an advanced propulsion.  Again, don’t miss his definition.  We talked near and intermediate term advanced propulsion concepts though it does not appear anything is really close at hand.  His timeline for a possible advanced propulsion technology was around 20 years.  He said not only do we need to understand the physics much better,  but the propulsion method much compete with current systems and produce benefits including cost benefits.  As far as choke points on advanced propulsion, he said understanding the fundamental physics involved was a big one.  We then talked about funding which is now mostly from companies and other private investor oriented sources.  I asked lots of questions about funding, especially how does one know when the point is reached to either kill the project or keep it going.  Don’t miss what he said about this.  Listeners also asked many questions.  In replying to one listener, he said it would be hard to beat chemical rockets to LEO but the door opens up BLEO though the Moon can be done with chemical rockets.  When asked about the anti-nuke movement and the impact on the nuclear rocket, he had some interesting observations, especially regarding the views of younger people.  When asked for leading advanced propulsion people and concepts, he mentioned former Space Show guest Dr. James Woodward and his work with Mach’s Principle several times during our show.  Greg was also asked about the work of Dr. Sonny White at JSC for warp drive and M drive.  Greg had much to say about his work including Q thruster and M drive.  John from Ft. Worth called in to talk about M Drive & Mach’s Principle along with gravity and magnetic frequencies.

In the second segment, Ashley sent in an email asking about going to the Moon and Mars for settlement and sustainability, wondering if advanced propulsion was needed for either location.  You might be surprised by Greg’s response to this question so listen carefully.  He did say there would be different requirements for the Moon and Mars.  With Mars, he also spoke about radiation and travel times.  Greg then had some things to say about artificial gravity.  One of his comments was that if we understood more of the physics, an eventual advanced propulsion system might enable an artificial gravity system without spinning or the need for tethers.  Brad in Tucson sent in a note asking about reusable first stage rocket launch systems.  Greg was delighted with the question as he works on such systems in his day job and he had much to say and offer about reusable first stage rockets.  He went through a brief summary of some of his work plus those attempting to design such systems including SpaceX.  I asked about a payload penalty with reusability.  Don’t miss his answer.  Our next caller was Marshall and he took us back to the artificial gravity discussion.  Marshal was asking questions about the amount of time spent in 1g as opposed to various fractional gravity loads.  As the program was ending, Greg received the final question which dealt with comparing the quality of government research to private sector research.  He reminded the listener that there very little to no government research funding for advanced propulsion, that it was almost all private sector funding.  He said the private funding was investor based so it comes with a commercial profit focus.

John Batchelor and I welcomed back Dr. Alan Stern to discuss New Horizons which is now closing in on its flyby of Pluto after a nine year plus mission from Earth. We talked about the condition of New Horizons, the actual flyby, the collection of data and the transmission of the data back to Earth. We also discussed the Hubble Space Telescope findings about the strange tumbling of several of Pluto’s five moons with data from New Horizons starting to confirm the Hubble images. Alan talked about the formation of moons in the Pluto system and said it was similar to the Earth-Moon formation. He said Pluto was the only other place in the solar system like our Earth-Moon system and it lies on the far outer edge of our solar system billions of miles from Earth. New Horizons is an exciting mission with lots to look forward to as the flyby happens and we get the data back from the satellite.

We welcomed back Dr. Robert (Bob) Zubrin to discuss the upcoming Mars Society Convention in Washington, DC from August 13-16, 2015 (see www.marssociety.org/a/marssociety.org/www/conventions/18th-annual-international-mars-society-convention). During our 1 hour 45 minute program without a break, Dr. Zubrin not only told us about the upcoming Mars Society Convention for 2015, but talked about Human Spaceflight (HSF) to Mars by addressing many specific issues, concerns, and topics.  Starting off with the Convention, it is August 13-16, 2015 at the Catholic University of America in Washington, DC.  Special hotel prices are available at the Phoenix Park Hotel (see www.marssociety.org/conventions/18th-annual-international-mars-society-convention/hotel-and-transportation for reservation details).  Bob told us about the keynote speakers but also the special format this year for debates. Several topics will be debated including Moon vs. Mars, Mars One feasibility with the MIT team and Bas from Mars One, how best to achieve commercial space plus other topics.  Bob then started getting questions from listeners & myself on a wide variety of Mars HSF mission topics.  To start with, I asked Bob to comment on what several recent Space Show guests have said about our not being ready for HSF to Mars for a variety of reasons including radiation, other human factors, the costs, and the trip risk which would turn it into a survival mission and nothing more.  Before Bob responded to my specific question, he commented on the recent radiation paper, “How a trip to Mars would mess with your brain.”  Bob was very critical of this paper and spent time going through it and showing where he believed it to be bogus.  You can read Bob’s critique at www.marssociety.org/home/press/announcements/invalidclaimsmadeforwhathappenstoyourbrainonthewaytomarspublication.  Bob spent a good amount of time debunking the original article so don’t miss his comments.  Before moving on, I again asked Bob to respond specifically to what my guests had said as none of them mentioned the paper in question.  We had an interesting discussion on risk taking and the role of government as part of our discussion.  John in Florida called to ask about the concept of a nuclear explosion on Mars per Space Show guest Dr. John Brandenberg.  This led to questions about shortages of PU238, space policy & political leadership. Doug had questions about an Earth Return Mission and later he eventually called in to get a more precise answer to what he was asking.  We talked about one way missions, how best to explore Mars, and the responsible way to tackle the eventual settlement on Mars.  Emmet from NY called in to ask about Elon Musk Mars and NASA plans and why they seem to ignore going for artificial gravity.  Again, Bob had much to say about this issue which he said was different for Musk and NASA.  He felt Musk would address it as the challenge became more real for him.  As far as NASA goes, he said it was criminal to have avoided the issue for decades.  Don’t miss his comments.  Jackie emailed in a question about character in the book “The Martian,” wanting to know if crew were stranded on Mars could they actually do some of the things the character in the book did to survive.  You might be surprised by Bob’s answer.  Matt in Germany asked a question about Mars via the Moon, BJohn asked about the use of a cycler for Mars transportation & Kirk called to talk about an article he had read about fossil ice at Valles Marineris.  Kirk will post a comment about this on the blog after the show is archived.  Next up was the subject of terraforming Mars. Bob had much to say about this plus he offered a possible terraforming timeline. Doug then wanted to know if Bob was referring to paraterraforming when he mentioned the use of Domes on the Martian surface but Bob said no.  Tim called to talk about the radiation paper discussed earlier and mentioned a second experiment saying that antioxidants negated the radiation effects. Bob was not familiar with the second study but summarized his comments about the paper.

BJohn emailed in about rocket advances from the Saturn V for a Mars mission, we talked about what it would mean to use a Falcon Heavy for Mars missions, then Marshall called to inquire about sources of power on Mars, particularly nuclear and getting a large enough nuclear reactor to Mars.  Marshall and Bob talked about a Topaz like reactor.  Another question came up about using the Martian moons for the early human missions rather than Mars.  Bob explained why in his mind this was not a good idea.  He then compared the radiation dosage of long term ISS usage for ISS astronauts to the transit time and radiation dosage for a Martian crew.  Don’t miss what Bob had to say about this.  In Bob’s concluding comments, we focused on the upcoming convention but also on the importance NASA and a HSF mission to Mars in the context of the world today.  This is an important part of our program so don’t miss it.  In concluding, Bob said “It is time again for NASA to astound the world to show what free men can do.”  You will likely hear me use Bob’s closing statement on many future Space Show programs.

We welcomed Dr. Erik Seedhouse back to the show for a variety of timely discussion topics. During the first segment of our 1 hour 37 minute program, Erik started out making comparisons with past polar exploration and going to Mars. He also said that going to Mars anytime in the foreseeable future would be a survival trip. We talked about Erik’s books on Virgin Galactic, Polar Exploration and Mars which will soon be released, and additional books on Dragon, Mars One, Mars via the Moon, and XCOR, all to be released over the coming months. Erik then spoke about his ISDC talk re comparing polar exploration to going to Mars and commented on the speaker following him, Dr. Logan (he was not sure of the first name but we think it was our friend, Dr. Jim Logan). He talked about radiation shielding and water per what Dr. Logan had to say including the need for 10 meters of water shielding to equal the protection here on Earth. Erik had much to say about radiation and shielding which prompted multiple emails from Dr. Doug in S. California seeking clarification and adding to Erik’s comments. I read all of Doug’s radiation themed emails throughout the first and second segment of today’s program. Don’t miss Erik’s conclusions regarding the radiation risks and shielding needs for a Mars mission, how astronauts would live and work on Mars as well as the Moon. Erik next talked about Virgin Galactic and XCOR saying he thought XCOR would be the first to fly commercially. When asked about the biggest passenger risk on a suborbital flight, Erik said it would be the cardio-vascular risks. Erik got questions regarding SpaceX, Elon Musk, and the Mars Colonial Transporter. He again stressed the way to go to Mars was via the Moon and that would be his preferred space policy. He also put forth his Mars simulation study plan. Don’t miss it, I think it’s a good one.

In the second segment, John from Florida called to comment on delays and how long commercial suborbital flight was taking since the success of Spaceship 1. John seemed to compare the lack of progress with suborbital flight to how much progress was made with aviation and in particular jet travel. I took the first pass at responding to him, then Erik offered his comments. What do you think? Let us know on the blog. Erik was then asked about other human factor issues than radiation. Dr. Seedhouse went through a laundry list of health risks and concerns for astronauts in deep space and on long duration spaceflight. He was then asked about the regulatory regime for suborbital space, then he wanted to define space given Virgin Galactic may not flight beyond 50km which is not space. Don’t miss what he had to say about this and the overall health risks for astronauts in deep space. Near the end of the show, Erik addressed space settlement. He said it would be a natural expansion and would happen automatically with returning to the Moon and going to Mars via the Moon. In his concluding comments, he suggested that advocates and space enthusiasts need to adjust expectations and understand the technology involved because its harder and more costly to do things in space, including suborbital space, than originally thought and expected.

Welcome to our final Open Lines program for May 2015. During the first segment of our 1 hour 46 minute program, I threw out some suggested topics for discussion including Space Show website changes, our planned crowd funding project for financing the new website, a satirical article in The Onion, “NASA Announces Bold Plan To Still Exist By 2045″ (see www.theonion.com/article/nasa-announces-bold-plan-still-exist-2045-50398), and the possibility of the government regulating lunar and asteroid mining plus other topics as well. Tim from Huntsville was our first caller. He misunderstood my comment about The Onion article and wanted to know what bold plan NASA was announcing for 2045. I clarified the matter with him but he still seemed to think the article had more to do with the reality of NASA today rather than just a comedy article in The Onion. I disagreed with him but he did say that space policy based on a two term administration and then changing was not productive and should be changed. Later in my conversation with Tim I mentioned an LA Times article by Jerry Hirsch which was highly critical of Elon Must for taking government subsidies. Little did I know that this article would be the hot topic of the day on this Open Lines program. The actual article, “Elon Musk’s growing empire is fueled by $4.9 billion in government subsidies” can be read at www.latimes.com/business/la-fi-hy-musk-subsidies-20150531-story.html#page=1. As I sated on air with several callers and emailers, I thought the article was incomplete and a hit piece since it ignored the basic economic facts of government non-cash subsidies. Dennis Wingo called in to refute the article though Kelly Starks emailed us in support of the main theme of the article. During John’s call from Florida, I was asked to see if the article’s author would come on The Space Show. I commented that I was probably not that interested in talking to him and noted my experience with general audience journalists (not all of them) as compared to talking with space journalists. In the meantime, Marshall called to chime in on the presidential cycle and space policy and what it means for long term space projects. We did note several projects that have survived through various administrations such as Hubble, many of the planetary science missions, SLS and more.

In the second segment, Tom, a first time caller to the show from Seattle, wanted to talk about his view of the space industry being immature. By immature, he meant that doing only a hundred or fewer launches a year and not that much new being done in space indicated being immature to him. He also supported Rocket Lab, Planet Labs and the emerging cubesat industry. We talked about the need to lower the cost of space access to get more players and ventures in space. Michael Listner called into to talk in detail about the newly passed House commercial space bill. He said it was passed on party lines and would go to the Senate and there would have to be compromises for it to go to the President. He talked about problems areas including company liability for example. He also mentioned the new title for astronauts who will fly on the Dragon and CST 100, Government Astronauts. By giving the crew this title, they will not be designated spaceflight participants, thus their safety can be regulated NASA and the spacecraft will need some sort of certification or something to fly government astronauts on board. This will allow NASA to set crew safety standards. He referenced a Space Review article which you can read here: http://thespacereview.com/article/2759/1. Doug from S. California was our next caller. He introduced us to the term paraterraforming. Doug explained this to us in some detail. He also called it “reversible exploration.” This discussion included noting the ethical issues around any type of terraforming, radiation, energy requirements, and more.

We welcomed Dr. Ian Crawford to the program to discuss his work and paper “Lunar Resources: A Review.”  This paper can be found on The Space Show blog for this date and show, https://thespaceshow.wordpress.com.  In addition, Dr. Haym Benaroya co-hosted the program with me.  During the first segment of our 1 hour 20 minute discussion, Dr. Crawford explained the motivation behind his research plus I asked him about any surprises he came upon during his research.  Two areas that surprised him included Platinum Group Metals (PGM) and helium three (HE3).  He referred to HE3 several times but he discussed it in more detail in the second segment so I will defer until then.  We talked at length as to why the Moon was of interest. He talked about the scientific value of the Moon as well as learning how to do things in space that we will need later on gong to Mars or other destinations.  He said the Moon was resource rich but that we were only beginning to learn what we can do on the Moon and how to benefit from its resources.  Both our guests were asked if we were nearing the maximum point of benefit for remote sensing lunar operations.  The answer was yes but we were not there yet as more improvements in HD resolution and other areas are yet to be realized.  That said, robotic lunar exploration is now available as is human exploration.  Both Haym and Ian said the format for lunar exploration would likely need to be public private partnerships, even with international missions.  They also said we need to start doing it now. Haym said it was a bootstrap type of process and Ian said it was a learn as you do process.  On the job lunar training!  Haym also mentioned that 3D printing and robotic systems would lead the way before humans.  He also suggested they might evolve to the point that they can do construction so astronauts going to the Moon do not have to be “construction workers.”  As the segment was ending, Ian was asked about the needed legal infrastructure to commercialize lunar resources.  He had much to say about this before the segment ended.  As the segment was ended, an 11th hour question was asked about making rocket fuel from water ice & could we do it today.

In the second segment, Doug from S. California called & wanted to know if there was any resource needed for settlement on the Moon that was completely lacking or unavailable on the Moon.  Ian said it was a complicated answer given that a resource might be there but the needed energy to use it might make it impractical. He said for a long time to come we would be making things on Earth and importing Earth products to the Moon but as Haym said earlier, it would be a bootstrapping and learn as you go and do process.  Ian then talked about the solar wind and its deposits of material in the lunar soil such as nitrogen, HE3 and more.  He talked some about polar ice, then told us why he did not think there was an economic case for HE3 and that its claims were vastly overstated.  Doug got in a question about inflatable lunar structures and Haym said they would need to be made rigid but otherwise a good way to start.  Doug did not like the Caterpillar analogy for lunar mining equipment given such equipment would not look like Earth equipment, especially since here on Earth equipment works in 1G.  We talked about the likelihood that companies like Caterpillar would still have their orange paint and logo on the Moon because if there was an equipment business case to be made, existing companies would likely want to compete in that market & Caterpillar is an industry leader.  Near the end of the discussion, Frank sent in a question asking him about his comments in his paper about cis-lunar being the first market available for exploitation.  Ian responded to Frank’s question so don’t miss the answer.  Jane emailed in asking if there was a resource case to be made for HSF to Mars.  Another Frank emailed in from Dallas asking about U.S. space leadership and could the international community carry on a robust lunar development program with the U.S. sitting on the sidelines.  Dr. Crawford talked for some time addressing this issue.  He also pointed to additional resources by checking out the Global Exploration Strategy and The International Space Exploration Coordination Group.  The latter has a document on its website outlining the major benefits of space exploration, www.globalspaceexploration.org/wordpress/wp-content/uploads/2013/10/Benefits-Stemming-from-Space-Exploration-2013.pdf.  Before the program ended, he was asked about using asteroid resources so don’t miss his response on this timely topic.  In closing comments, Haym made the case for the Moon being the logical next step on our space development timeline.  Ian supported those comments adding even more rational to what Dr. Benaroya said.
