We welcomed back Charles Miller to discuss in detail the recently released NASA Study, “Evolvable Lunar Architecture that Leverages Commercial Space Capabilities and Public Private Partnerships.” You can read and download the report, “Evolvable Lunar Architecture that Leverages Commercial Space Capabilities and Public Private Partnerships” at http://titan04.ksc.nasa.gov/shuttle/nexgen/Nexgen_Downloads/NexGen_ELA_Report_FINAL.pdf. During the first segment of our 1 hour 39 minute show, Charles introduced us to the study, the background as to why the need for the study, plus he said that to find an affordable way to move humans out into the cosmos there needed to be an affordable way to do it. He briefly summarized the history of efforts to return to the Moon since Apollo, then explained why this new approach, modeled after the COTS program, was so much better. Through the creative use of the public-private partnership program, returning to the Moon can be easier and more affordable. Charles was asked lots of listener questions including questions that addressed the TRL level of both NASA and the private companies to go to the moon, public and private risk taking, commercial competition, and the strategic use of fuel depots to further reduce mission costs. He explained their program step by step through three phases. Listener Dan asked a series of question about robots being serviced on the Moon, asking if the humans would be better placed elsewhere to control the lunar robots using low latency telepresence rather than humans on the Moon. Don’t miss how Charles responded to this series of questions that Dan emailed us. BJohn was also active with questions ranging from asking about the Lunar Mission One program to questions about the costs and assumptions used in the NASA study, even the use of GEO. Other listeners wanted to know about lunar settlement as part of this study, lunar habitats, and using L2 rather than the lunar surface. Listeners also asked Charles about lunar microgravity issues and radiation. Charles had the most to say about radiation issues. Later in the segment he said the plan called for a migration of the initial program to something like an international lunar authority modeled after CERN and modern airport authorities. Dan asked another question about getting astronauts off the moon in an emergency wondering if there would be greater safety margins if humans were not required on the lunar surface. Charles indicated that there would be a lunar escape system on the Moon. When questioned about the economics, it was clear that the study had in mind to facilitate human expansion BLEO so options not expanding the human presence BLEO were not options considered for the study. Todd asked if SLS was considered in their analysis. The answer was no as they only looked at commercial launch options, not government launchers. More questions came up about how the project would be financed relative to the NASA budget. Don’t miss this analysis and explanation.

In the second segment, BJohn asked about the Falcon Heavy regarding fuel depots. Charles said it was a LEO only launcher so not considered in their study. More listener questions came in regarding depots. BJohn also asked about the use of GEO. Charles explained why this was not an option. Eric and Charles had quite the email exchange about needing humans on the lunar surface. Charles said they were primarily there to repair and maintain the robots and equipment. Eric kept asking about using robots for the repair and maintenance but Charles said that technology was not available at this time. Their give and take was a good discussion of the subject. As Charles pointed out, since a commercial company would be on the moon with the robots, they would have every reason to advance their technology to be more cost effective so moving toward robotic servicing of the lunar surface robots would be something a company would be motivated to do to save on operating costs. However, that technology was not available today. Listener Josh wanted to know about other potential lunar businesses including lunar tourism. Charles was asked about lunar cubesats, then near the end he was asked about property rights and lunar resource exploitation. As the program was about to end, we talked about the political process and progress the study needed to make as it worked its way through the policy makers, Congress, and others.

Dr. Robert Farquhar, Sunday, 3-25-12


Guest:  Dr. Robert Farquhar.  Topics:  Our discussion centered around his memoirs in his new book and his space involvement over fifty years.  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. Robert Farquhar back to the program to discuss his new book, “Fifty Years On The Space Frontier: Halo Orbits, Comets, Asteroids, and More.”  If you purchase the book using the following Amazon link, Amazon will make a contribution to The Space Show/OGLF:  www.amazon.com/Fifty-Years-Space-Frontier-Asteroids/dp/1432759272/ref=onegiantlea20.  Dr. Farquhar started out by talking about his early interest and work in aviation and space, gradually taking us up to and including the missions he has described in his excellent book.  Among some of the points he made included that in the early years, there was much more independent freedom for those working on missions while today things are done by consensus, committees, etc. When asked if the missions were improved and the costs contained by the newer methods, he said he did not think so. Its an interesting discussion you will want to hear.  He highlighted several of the early missions and we talked quite a bit about the halo orbit and Lagrange points.  He also told us stories about plaques he snuck on missions, trying to arrange one mission arrival to coincide with his birthday and more.  Great stories and for sure you will have a smile if not an outright laugh when listening to Dr. Farquhar.  He also said all of the stories he was telling us were in his book.  Later in the longer first segment we talked about human spaceflight and why he supports SLS/Orion.  This discussion took us into a more extensive conversation about L1 and L2 missions in the Earth-Moon system.

In the second segment, listeners asked about L4 with the 2010 TK7 asteroid, New Horizons, Pluto, Mercury, and more.  Bob told us additional stories, including some about the photos used in the book.  The JWST came up as did additional funding for NASA.  Bob did not think more funding was needed but thought the existing money could be used better.  The Kuiper Belt was discussed as were asteroid issues in general along with specific missions.  Neat the end of the show, I asked Bob if his space work & expertise has given him perspectives on the existence of ET.  This is a brief discussion you do not want to miss!
