We welcomed Dr. Philip Metzger to the program to discuss the topic of a coming space resource revolution because of the prospects for a rapid advancement of robotic industry in space.  Please visit his website at www.philipmetzger.com. During our first segment of this two hour five minute program, Dr. Metzger explained the need for space resource usage as a result of a growing Earth population, increasing energy demands, industrialization & an overall feeling of being “squeezed” regarding future demand and resource usage.  From this point, he took us through the technologies, advancements and some visionary plans for setting up a commercial industry in space for space mining robotics and ISRU technologies which are available today.  Dr. Metzger was clear in telling us that the NASA charter was about exploration, not starting up space industry.  We then talked about the ways that industry can access the advance technology created by the NASA exploration and science programs.  Our guest provided us with several robotic examples, including the possibility of making heat shields from Phobos materials which could go a long way toward making a Mars mission affordable.  We talked about technology readiness levels, TRL 1-9.  Phil explained what the various levels meant & how the technology development is passed on to the next development group as the level advances.  I asked our guest to describe a typical day in his lab.  Starting at 6:45AM, Dr. Metzger described his duties and functions and those of the rest of the lab workers.  As you will hear, it’s a mixture of administrative, design, computer work, testing, retesting, & equipment manufacturing.  3D Printing was discussed in some detail and was actually a discussion topic throughout the entire program.  We talked about our being able to repair robotics as compared to building the robotics to avoid needing repair.  Listener Mike sent in an email to inquire about 3D printing, teleoperated & AI robotics for self sustaining lunar/asteroid economies. He also wanted to know how human space exploration fit into the robotic model.  Phil had much to say in response to Mike so don’t miss this discussion. Near the end of this segment, we talked about robotics & the communications time delay, even for the Moon, and what this means for HSF & robotic development. Another concept introduced to us was that of self-sustaining robots that do not need to continue being launched to their destination! Near the end of this segment, Phil introduced us to Lizard Scale Robotics & the different categories going up the scale of robotic development to the top level human scale.

In our second segment, Doug called in from S. California to inquire about starting an affordable industry, financing, and the use of lunar propellant ice.  This took us to a discussion of setting up profitable ventures for space industry development. Phil talked about a new spaceport concept starting with spaceports here on the ground, then in LEO, on the Moon, & then moving out to Phobos.  For a profitable venture, he did say the time line was still too long for capital investment so we discussed public/private partnerships. Also in this segment, we talked hardware designs, the need to start with low technology, even clumsy robots and evolve upward, but avoiding launches & most everything being made in space. We talked about launch capabilities, heavy lift, & getting a specific mass to where it needed to go.  Closing the business case came up & our guest talked about the old “impoverished view” as compared to a new, expanded, multi-potential global view. Don’t miss this discussion.  Mike sent in another note about what it might mean to be second & the value of the exponential potential.  Phil took us through this discussion which made it crystal clear why maintaining our space leadership or being part of it on an international partnership level was so important for our future.  In this context, Dr. Metzger talked about widespread participation in space development for multiple co-owners.

We welcomed our panel members and the live Rocky Mountain College student, professor, and community audience to our afternoon 1 hour 34 minute panel in which we focused on human spaceflight, the Saturn V, the Saturn 1B, and the Space Shuttle, along with space science, risk taking, and what each panel member thought was most valuable for scientific reasons in the solar system.  We took many audience questions on a wide ranging group of topics including why spend money on space, especially in this difficult economy, solar cells, Boy Scouts and space, and what it was like to walk on the Moon.

http://thespaceshow.files.wordpress.com/2012/11/adamo-eml2roundtripr2.pdf.  We welcomed Dan Adamo back to the program and Dr. John Jurist as co-host for this special webinar addressing trajectory analysis for an EML2 mission and more.  On The Space Show blog, you will find Dan’s PDF document used during the webinar, a link to the movie he played in the second half of the webinar, and his Phobos-Grunt analysis paper we discussed near the end of the webinar. During the first hour of the webinar, Dan took us through the trajectory analysis to Earth-Moon L2 per his PDF document.  We talked about why EML2, libration points in general, and how such missions are planned.  If the resolution on the webinar video for the charts and tables used during this segment are difficult to read on your computer, please bring the document up on the PDF on The Space Show blog and follow along that way.  Dan took us through Table 1, HALO orbits, and the HOI as well as the Trans-Lunar Insertion points.  We talked about orbital characteristics, delta V, rocket size, and more  We also talked about the position of the Earth, launch windows, the Moon, & other factors influencing the planning of the mission.  While at times the discussion may seem a bit technical or overwhelming for those of us having never done mission planning at this level before, all of us will certainly have a better understanding of the factors considered and influencing both robotic as well as human spaceflight missions.  Near the end of the segment, we talked about the SLS and heavy lift & how payload capacity interacts with mission & trajectory analysis. 
 
     In the second hour of our webinar, Dan took us through his HD movie of the orbital trajectory talked about during the first segment, stopping it at intervals for specific explanations and questions.  The movie is in the QuickTime format but you can see it both on the webinar or by using the URL provided on the blog.  We took several listener calls & questions.  One asked Dan about the differences in planning for the robotic vs. the HSF mission using MSL & Curiosity as an example.  Dan pointed us to a YouTube video he made a few years ago with Dr. Logan using these tools for a Deimos mission (www.youtube.com/watch?v=X10GAqA4Ky4). Another listener called wanting to know the likelihood of an EML2 mission actually happening.  Dan explained why he believed this mission to be the next stepping stone in HSF.  More was discussed about SLS with Dan raising some concerns about its real capabilities & wondering if Congress is being sold unrealistic expectations. We talked about heavy lift in general & with the support of properly placed depots.  SLS and the difference with a Falcon Heavy were also discussed in terms of what the differences would mean in payload, number of launches, costs, risks, etc.
