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.

Dr. Farouk El-Baz, Friday, 8-24-12


Guest:  Dr. Farouk El-Baz.  Topics:  Apollo lunar landing site selection, lunar geology, Mars-desert analogs and more.  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 Dr. Farouk El-Baz to The Space Show.  Please visit his website for lots more information on the topics we discussed, lots of great pictures, plus many additional important topics, www.faroudelbaz.com. We started our discussion with Dr. El-Baz having a Star Trek shuttle craft named in his honor. Its a great story you will enjoy hearing. From Star Trek, we got down to business and wanted to know about the Apollo lunar landing site selection process. Dr. El-Baz told us how they did it, especially given the absence of any real information about the lunar geology and surface.  Three of the concerns he mentioned included the site being free of rocks, absolutely flat, and making sure the Lunar Lander would not sink in the lunar dust.  What’s more, Dr. El-Baz was 29 years old when he was in charge of doing this.  As you will hear, age is an important part of this discussion in the second segment near the end of the program.  I did ask Dr. El-Baz about selecting sites using Egyptian mythology as conspiracy theories suggest, plus his response to those who do not believe we ever went to the Moon. With the latter point, he had much to say about Moon rocks as proof of our lunar visits.  His comments on Orion and mythology were very interesting.  Another question asked him dealt with the shutting down of the program.  NASA risk averseness was the top reason.  Nels asked many questions about a possible Apollo polar orbit and lunar ice.  Our guest had much to say about this, the sun angles needed for landing, lighting, and more.  As we moved to lunar commerce, our guest talked about mining titanium and HE3 but not at this time.  I asked Dr. El-Baz about the Apollo-Soyuz Test Flight (ASTF) and working with the Soviets, then we returned to the plausibility of lunar commerce at this time.

As we started the second segment, we talked about commercial ROI opportunities for cargo to the ISS by the private companies but he suggested everything else was more distant and would probably need testing & seeding by the government.  I then asked him about his work studying deserts and using Earth deserts as analogs for studying Mars.  Dr. El-Baz had much to say about deserts, Mars, about their formation by rivers that had dried up & were buried under sand and how they know that.  We talked about Earth movement, especially the SaharaDesert, and the impact of natural geological events on climate change.  Imaging satellites were discussed & I asked our guest if we would have been able to have today’s knowledge were it not for the space program.  Don’t miss his fascinating answer.  At another point in our discussion, Dr. El-Baz mentioned 126 separate university research projects during Apollo.  The last listener question asked our guest about the extremely young age of the Apollo scientific & work force.  Dr. El-Baz had much to say about this, said that the work could only have been done by people in their 20’s and 30’s.  He said the older folks need to step aside and let the young people go forward, make the mistakes & solve the problems.  In the end, age made a huge difference for the good of the Apollo program.  Our guest also commented on our present day aging space & technology workforce.

Please post your comments/questions on the blog.  If you want to email Dr. El-Baz, send your note to me & I will forward it to him.
