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.

Please post your comments/questions on The Space Show blog above.  You can reach Dr. Crawford or Dr. Benaroya through their university websites or me.

We welcomed back Professor Haym Benaroya to take us through the steps necessary to establish a lunar settlement, the challenges, our initial TRL and more.  During the first segment of our 97 minute program, Dr. Benaroya advocated for the Moon before Mars and stated his reasons which he repeated several times during the interview.  We talked about the size of the launch vehicle needed for establishing a lunar outpost and then launch costs came up, especially with regards to the proposed Falcon Heavy.  Our guest was asked about one way lunar missions which he did not think possible anytime soon and here he referenced the history of psychological problems encountered by many in spaceflight.  At this point, let me say that we received a few cell phone calls with unacceptable audio on their phone.  Since Dr. Benaroya could get most of what the caller was saying (I could not), I tolerated the poor quality calls for as long as possible and then terminated them.  Listeners, please, use a quality phone line to call the show.  If your call is garbled, I will disconnect you.  Doug called from S. California to talk about consumables being the largest part of the mass. He talked about reducing the mass by using lunar water, recycling, etc.  Dr. Benaroya explained that would not happen right away so for the early stages of an outpost, mass from Earth will be the name of the game. Other topics in this segment included the use of lunar robotics, TRLs today and for the future, & incremental engineering. Dr. Bill Rowe called to talk about medical issues such a heart attack in space, mall absorption of drugs in the GI system, & the need for subcutaneous pharmaceutical administration in space.  Lunar dust was an issue & John from Ft. Worth called to ask our guest to talk about the dust & why it was so challenging to deal with re astronauts and equipment.

In the second segment, we talked about the role of structural and civil engineers, how they go about defining the environment they will be working with and more.  All of this was in response to the question of how does one actually go about building a lunar outpost given one does not exist.  Haym talked about radiation, microgravity and the likelihood that the first crews would be there for six month and return and live in a pressurized cylinder of some sort.  Lunar manufacturing was a discussion topic as was ISRU, 3D printing & the maintenance and repair of lunar equipment.  Haym responded to a question about possible Moon-Mars synergy.  Doug email in questions about inflatable structures and Haym talked about the need to make them rigid.  Doug also asked about duplicating 1/6th g here on Earth and the use of a short arm centrifuge.  Near the end of the show, Haym said the barriers were really political decisions, not the engineering, physics, medical, etc.  He also said it would a long time to build out a lunar outpost and we should be patient.

We welcomed back to Hotel Mars Dr. Haym Benaroya from Rutgers University. Dr. Benaroya discussed the NASA LADEE mission, lunar dust issues, the lunar surface, the importance our astronauts returning to the Moon and the Lunar Dust Experiment which so far has proven to be inconclusive regarding the questions it was to solve. Dr. Benaroya went over the toxic and corrosive nature of lunar dust to both humans and equipment, had similar things to say about Martian dust, and talked about how important it is for us to go back to the Moon. He also made the point that we should have a permanent settlement on the Moon and not just use it as a way station stepping stone to Mars, abandoning it again once we are on Mars. The three of us discussed the LADEE project in detail (as much detail as we could in this short segment). We also talked about its end which should come April 21 by crashing into the far side of the Moon.

We welcomed Dr. Haym Benaroya, mechanical and aerospace engineer at Rutgers University, back to the show to discuss lunar thermal and seismic analysis, space policy, human spaceflight, Mars, and more.  Our intention was to do a one hour program but due to incoming listener phone calls, this program lasted for 1 hour 39 minutes without a break!  In addition, the discussion at times with callers was quite heated, very passionate and ripe with disagreement, especially between callers and myself.  Frankly, there were times I just had enough of the gloom and doom and the la la land fantasy stuff so I blasted back on what the callers more than the guest were saying.  We started the program with an update from Dr. Benaroya on thermal and seismic analysis of lunar data collected from sensors left on the Moon by the Apollo missions.  The data has been run through new models for up to date processing.  As it turns out, for seismic activity, an igloo like structure which Dr. Benaroya described is probably the best for the habitat. Also, he said only flimsy items such as an antenna would like be risky structures due to lunar seismic activity.  I asked him to compare lunar seismic activity to the seismic activity of California and Japan.  We have it much worse here on Earth!  We talked about radiation issues & Haym suggested about 10 feet of regolith on the top of the hab would probably be OK other than for a solar event.  He also said much more data was needed for actual lunar structural engineering.  I asked him what the first lunar settlers would do during their day and this took us to HSF to Mars issues, microgravity concerns, and the Moon as a stepping stone to Mars.  John Hunt was the first of the callers, focusing on policy with the politicians.  Haym talked 3D printing with him, then I asked John if the program he was describing could be done in 10 years.  After forcing him to provide us with a yes no answer, he said no. Haym said the same but both agreed technology was not the problem, leadership was the problem.  We talked the need for profits for private ventures and opened up public/private partnerships for discussion on the show.  I asked both how to start implementing their plans & that was the opening salvo of the fireworks that unfolded for the rest of the show.  Doug called next and talked about his ideas for what astronauts on the Moon would do and his lunar development ideas.  I then challenged both caller and guest to outline their steps for making their happen.  I thought their implementation plans were severely lacking and opened up on each of them but more so on Doug for the balance of his call.  Haym said the first step was to rebuild U.S. launch capabilities. Doug had a different first step & talked about government funding as in a private/public partnership similar to what SpaceX has with NASA for Falcon.  I asked Dough how he intended to sell the importance & value of the program he suggested to those controlling policy and funding.  See what you think of this discussion & post your comments on our blog.  After Doug cleared the line, Charles Pooley called in & at one time I said he was the longest playing broken record in Space Show history! I told him he was full of doom and gloom and other people see things differently and I did not want is view of things to be right or prevail, suggesting others see things differently than he does. Again, your comments are welcome.  Near the end, I simply was rejecting the “dismal situation” facing our space program. While Haym agreed that things were not good today, he talked about how he inspires and works with his students so they can create a positive space environment during their careers and for our future.  Just before the show ended, Tim called at the last minute and I promised to send him a Timex given his rotten sense of timing show after show. With Tim, we talked propulsion, Zubrin’s thoughts on going to the Moon, & the two private Mars missions on the drawing board.  In his concluding remarks, Haym explained why he was not supportive of either Inspiration Mars or Mars One.

Please post your comments/questions on The Space Show blog. Haym can be emailed through me or his Rutgers website.

Space Show Webinar with Dr. Haym Benaroya, Dr. John Jurist, Sunday, 2-17-13

Behind The Scenes Engineering for Space Structures and Infrastructure

http://archived.thespaceshow.com/shows/1951-BWB-2013-02-17.mp3 (audio only)

http://vimeo.com/channels/thespaceshow  — Video

Guests:  Dr. Haym Benaroya, Dr. John Jurist.  Topics:  Engineering space structures, hardware, and habits for LEO, the Moon, and Mars.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, https://thespaceshow.wordpress.com.  Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information.

     We welcomed our main guest Dr. Haym Benaroya and co-host Dr. John Jurist to our first Space Show webinar for 2013.  As Dr. Benaroya is a mechanical and aerospace engineering at Rutgers University and well known for lunar architecture and engineering structures, we asked Dr. Benaroya to take us behind the scenes for a look into the engineering needed to have something in LEO, on the surface of the Moon, or Mars.  Dr. Benaroya prepared a special .pdf presentation for us which is on The Space Show blog per above.  I urge you to follow along with the .pdf slides as Dr. Benaroya discusses space engineering.

     During the first half of this two hour five minute webinar, Dr. Benaroya started out by discussing some of the basic issues in space engineering including gravity.  He started with Slide 2 and talked about each item and the engineering considerations associated with it, both here on Earth and in space.  As you will hear, not only are the engineering considerations significantly different between Earth and space, but many are also different from one another depending on if the project is in LEO, on the Moon or Mars.  Make sure you follow along with him using his slides.  Listeners, Dr. Jurist, and I asked Professor Benaroya many questions about lunar based habitats, LEO habitats, shapes, pressure forces, regolith issues, heat issues, and more.  Referring to Slide 5 Dr. Benaroya talked about gravity issues and concerns.  Slide 6 was about lunar dust issues, tidal forces, seismic concerns.  We compared seismic reinforcing in San Francisco or other terrestrial earthquake zones to what would be needed on the Moon.  The subject of engineering for extreme and rapid temperature changes came up for LEO, the Moon & Mars.  Dr. Benaroya suggested many times during our discussion that we would need to use ISRU given the high cost of getting materials to space.

     In this first segment, other topics included the potential afforded lunar engineers by having a Lunar Space Elevator available and even a lunar bulldozer!  The subject of heavy lift came up as it always does on these programs and all of us talked about fewer larger launches as compared to many smaller launches, even using depots. Doug called in to argue for the Falcon Heavy.  As Dr. Jurist pointed out, putting mass on the Moon is about 10% give or take of the rockets IMLEO mass capability.  In responding to Doug, both Dr. Jurist & Dr. Benaroya illustrated the difference between the Falcon Heavy and SLS regarding landing a specific mass on the Moon.  Just before the segment ended, in responding to a question from Dr. Jurist, Professor Benaroya suggested that each person on the Moon would need about 20 times his or her weight in mass on the lunar surface for around a six month stay.  To determine the most cost effective way to get the needed infrastructure and mass safely to the lunar surface, lots of issues go into the trade studies to determine the best approach, including launch vehicle choice.

     In the second segment of our webinar, we took a call from John in Florida who wanted to ask Dr. Benaroya about his earlier comment about using magnesium on the Moon as a type of rebar in lunar concrete.  We next talked about reliability, power sources, competing technologies and design issues.  One of the issues brought up was the need to design the structure to be successful during the design phase, not just the completion stage. This was a most interesting discussion, don’t miss it.  One of the points he made was that we can’t test structures in space like we can on Earth so engineering design issues must be considered & dealt with for space that would not be encountered on Earth.  He talked about the preferred shape for a lunar structure and advocated the arch as in Slide 21.  Our professor then talked about design standards here on Earth, the fact that we have none for space so all of the Earth standards are extrapolated to work in space though we have no history for doing this. Also, he talked about using four to five times for a safety factor where on Earth the safety factor might be more like 1.5 or 1.6.  We also talked about confidence intervals. While on Earth, something may be done with a CI of 95% or higher, he suggested that on the Moon or in space the CI would more likely be pretty low, around 70 or maybe 80%!  He cited dust design as an example of what he was talking about as dust is not a big factor in terrestrial engineering but it will be on the Moon or Mars.  Doug called again to advocate inflatable structures rather than the engineering and building of structures.  Prof. Benaroya suggested that they may be used early on but that most of the studies show their primary advantage to be in transportation because on the surface they have to be made rigid.  This is another discussion you don’t want to miss.  Near the end of our webinar, advanced manufacturing for the future was discussed.  Dr. Benaroya talked about advances in robots, layered manufacturing and 3D printing. He explained how these can really change the game for space structures, engineering, manufacturing, and costs.  Near the end, questions came in as to why the Moon instead of Mars, the 7-8 year time lines mentioned by the lunar companies and Mars One as well as wanting to know if space engineering was strictly an academic project or if it was being worked real time by companies that can actually make hardware.  As you will hear, it’s a combination of both at this time.  Dr. Benaroya kept talking about time lines 2-3 decades long and I asked him about speeding that up and the short time lines for the lunar and Mars One group.  He did not think the shorter time lines were feasible.  See what you think after you hear his and Dr. Jurist’s comments on emerging company time lines.  Dr.  Benaroya concluded by pointing out the popularity of these subjects in both undergraduate and graduate classes and the importance of student research and its benefits.

Guests:  Dr. John Jurist, Dr. Haym Benaroya.  Topics:  Space policy ideas as presented in our Op-Ed & Open Letter which you can read on The Space Show blog.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, https://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright.  We welcomed back Drs. Jurist and Benaroya to discuss our two articles to be published regarding U.S. space policy.  You can read the drafts of these two articles on The Space Show blog per the URL above for this particular program and date.  We are asking for your constructive feedback, comments, and questions as our intention is to refine both letters and submit them for publication.  All comments and feedback are welcome but the most useful feedback will offer suggestions for how to make our letters more effective in fostering space policy that supports economic, STEM, and space program growth on the civil side as well as on the private, entrepreneurial, & commercial side.  In addition, The Space Show suggests that listeners write their own 1,000 word Op-Ed and submit it to The Space Show.  I will put it up on the blog, plus offer you time on The Space Show to articulate your perspective and views. We know that some of you will disagree with what we have said and we do want your contribution to the discussion as you will hear during this program.  So do join in on the overall space policy debate.  Don’t just sit on the sidelines, get your ideas out there to advance the discussion.  During our discussion which was 90 minutes without a break, the three of us explained why we decided to write and publish our thoughts on space policy and our future in space, plus we went into some detail as to the content of leach letter.  We fielded several listener questions which offered suggestions as well as critiques of both our approach and our content.  Several of the listener comments offered no suggestions for making the letters more effective, opting instead to tell us where we were going wrong.  Please post your comments, suggestions, and feedback on the blog.  Any emails sent directly to me regarding our letters and this discussion will be posted on the blog in your name without any editing on my part.  If you want to send an email to Dr. Jurist or Dr. Benaroya, please send it to me at drspace@thespaceshow.com and I will gladly forward it for you.
