We welcomed back Dr. Doug Plata to the show to discuss his selected trades for his Cis-Lunar One Transportation Architecture.  You can find Doug’s Choices of Selected Trades document on The Space Show blog at https://thespaceshow.wordpress.com under the summary for this particular program and date.  In the first segment of our 2 hour 6 minute discussion, Dr. Plata started out giving us an overview of his project, mostly by reading to us the “Overview of the Cis-lunar One Architecture” which is part of his document on our blog.  In addition, Dr. Plata wants your feedback regarding his project, including constructive criticism.  You can email Dr. Plata at dougspace007@gmail.com.  After discussing the project overview with us, Doug started addressing the trades listed in his document.  We started with Trade 1 Launcher.  Doug went through all of his considerations for launchers, was clear that he was not ruling any particular rocket out of the question.  Make sure you note his “Table1: Choice of Launcher & Fuel.”  The led us to discussing payload issues for the mission.  Also note that Doug has named his lunar craft the Condor upper state LL as you will see that name show up throughout our discussion.  Doug then went to Trade #2 and discussed propellant choices.  Note his Table showing the specifics of his Choice of Fuels assuming 53 tons at LEO and a 15% dry mass.  He received several listener questions, including questions about where to on the Moon.  See Trade 8 Initial Landing Sites for his choices and reasoning.  We skipped to Trade 12 Power in Shadows.  He discussed power options in some detail and went through the four options listed in this trade.  Mary Beth sent in some questions asking Doug about his propulsion discussion and Marshall called in with a series of questions about ice and the regolith.  Doug then took us to Trade 17 Repairs.

In our second segment, Doug started with Trade 17 repairs, focusing on redundancy, spare parts, & surface equipment easy designs.  Later in the segment, Dr. Plata was asked about lunar dust and maintenance/problems for the equipment.  A listener emailed him about market possibilities, our guest fielded other listener email questions and then Doug addressed Trade 9 Landed Configurations including belly landings and tail landings. Trade 14 Surface Equipment was discussed, then John called in to talk about a needed detailed lunar surface survey.  I asked our guest for his detailed cost projections for his mission followed by his next step in promoting his architecture.  He talked about having called his Congressman, Representative Mark Takano.

Please post comments/questions/feedback on TSS blog per above.  You can also email Dr. Plata at his above email address, plus its on his trade document which is on TSS blog.

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.

Guest:  Dr. Doug Plata.  Topics:  Taking action on one’s space advocacy ideas.  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 Dr. Doug Plata to the program to discuss taking action on one’s space advocacy ideas and plans.  For examples of this, visit Dr. Plata’s  www.lunarcots.com for more information on his Lunar Cots idea and to sign his Lunar Cots petition which he talked about throughout our two hour program.  Dr. Plata said he was not around in the Apollo era plus he only started getting interested in space about 3 years ago.  I commented that he did not bring to the table disappointment and unrealized, perhaps even foolish expectations that many of us who were around during Apollo have experienced, including an expectation of lunar colonies and trips to Mars by now.  Doug had a clean slate to build upon, no legacy issues or unrealized expectations or anything like that.  Doug said his interests are to go BLEO but how?  Based on his analysis, he decided lunar development was first, researched Cislunar development, and developed his Lunar Cots idea based on successes for NASA public/private partnerships such as COTS.  From there, he developed the idea of the Lunar Cots Petition for people to sign and to eventually give NASA and other key policy makers.  He also mentioned that were he to advocate something, he felt it was his responsibility to technically know about the issues so he could accurately represent them to people.  He also said that one person, even with very small steps, could make a difference and he clearly walks that talk.  Part of his Lunar Cots idea addresses the need for a Cislunar Transportation System.  The first John called (from Atlanta) and raised the question about there being sufficient water ice on the Moon.  In his response, Doug referenced the LCROSS mission.

In our second segment, Doug took calls and listener emails.  The discussion about there being sufficient lunar water ice on the Moon continued.  He also talked about automatic equipment for lunar mining as compared to telerobotics.  Doug was asked who he talks with about Lunar Cots and the petition. We heard everyone, from the general public to space enthusiasts.  In talking about space advocacy in general, he said there were many paths and people had to find a path that made sense to them & then figure out a way to act upon their individual advocacy.  John called from Florida and asked about heavy lift and fuel depots.  Another Jon called from New Jersey to ask about doing something, anything, and the use of prizes. Even Charles Pooley got in on the discussion to talk about starting small and his Microlaunchers concept.  Toward the end, Doug was asked by a medical school student why he was not doing aerospace and human factors space medicine.  Also during this segment, both Doug and I talked extensively about finding something to do regarding one’s advocacy, even if it involved stepping out of one’s comfort zone and seemed to be too small an effort.  The reality is that to make a difference, even a small effort can be and is usually beneficial.

Please post your comments/questions on the Space Show blog.  You can email Doug through the address he provided on air or through me.

Guest:  Dr. James (Jim) Vedda. Topics:  Dr. Vedda’s new book addressing cislunar development rather than destinations.  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. Jim Vedda back to the program to discuss his new book, “Becoming Spacefarers: Rescuing America’s Space Program.” If you order the book using this Amazon link, Amazon will make a donation to The Space Show:  www.amazon.com/Becoming-Spacefarers-James-A-Vedda/dp/1477130918/ref=onegiantlea20. Dr. Vedda started our discussion by responding to my question about what he meant by “rescuing America’s space program.”  This opened the way for most of the first segment to lay out the recent history of our space program and how we arrived at where we are today, Sept. 29, 2012.  Issues talked about during this narrative included Obama Space, Constellation, SLS, congressional actions, partisan divides, space vision, goals, timelines, space telescopes, Orion, Earth/Moon libration points as a destination, and much more.  We talked about the purposes of various missions & plans and if the stated purpose was sufficient or not for spending public money on it and carrying it out to completion. We then shifted to the Romney Presidential Campaign Space White Paper (www.scribd.com/doc/106652769/Space-Policy-White-Paper?secret_password=a0i3o1yj25ed5ycop3w). Dr. Vedda mentioned that space policy has not always been bipartisan & he provided examples to support his statement.
    We started the second segment by talking about our being in the training or initial phase of his three stages of space development.  The other two phases include cislunar development followed by space settlement & expansion throughout the solar system.  Dr. Vedda made the case for proximity operations in our space development program plus the need for strong public/private partnerships and when warranted, international cooperation with space projects.  Later in this segment, I asked Jim to outline for us his action plan, just how he would initiate a space development program per what he outlines in the book & discussed with us.  In response to my question, Jim outlined several initial steps that need to be taken to get the ball rolling.  See what you think of them and let us know with your blog comments.  We also talked about the general public, how Jim would make his case were he speaking at a Rotary lunch, and the best way to have a say & impact policy makers.  One of our final topics included the newly proposed bill to do multi-year congressional funding of space projects, make use of a to be created space project oversight panel, and have the Administrator serve a ten year term.  As you will hear, we supported the multi-year funding part of this proposed legislation.
Note below that you will find a special PDF slide presentation supporting Dr. Vedda’s book.  I strongly urge you to follow along with it during our discussion.

http://archived.thespaceshow.com/shows/1783-BWB-2012-05-28.mp3

Guest:  Dr. John Lewis.  Topics:  Asteroid mining, Chinese space program.  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 Dr. John Lewis to discuss asteroid mining and the Chinese space program. You can order Mining The Sky: Untold Riches From The Asteroids, Comets, And Planets by Dr. Lewis as we talked about his book throughout our program.  If you use this Amazon URL, Amazon will make a donation To The Space Show/OGLF:  www.amazon.com/Mining-The-Sky-Asteroids-Planets/dp/0201328194/ref=onegiantlea20. Our first segment focused in on asteroid mining, where are today, its future, legal issues to be settled, risks, and more.  Near the end of this segment, we also talked about the Law of the Sea Treaty, the common heritage of mankind and revenue sharing ideas, all of which would be detrimental to asteroid mining and expanding space commerce.  Earlier Dr. Lewis referenced the Keck study, The Asteroid Retrieval Feasibility Study which says we can capture a certain size NEO and put it in orbit around the Moon. Dr. Lewis carefully went through the pros and cons of doing this.

In the second segment, Tim called in and continued the revenue sharing and common heritage discussion.  Dr. Lewis then cited his family history dating back to 1625 coming from theNetherlands with the West Indies Company, then staying here and moving west rather than returning to theNetherlands.  He drew parallels with this and potential space settlement and risk taking.  Next, we talked about the Chinese space program, their space station, the upcoming taikonaut launch in June and the fact that they are actually “bending metal” in making hardware for going to the Moon, unlike the Indian program which is still largely talk.  Near the end of the segment, we talked about lunar mining, the needed future vision and leadership, the need to be a multi-planet species and why.  Our discussion with Dr. Lewis is full of important information so I urge you to carefully listen to this program and use the internet to follow up on many of the topics and issues he brings to our attention.  For example, you might find it interesting to see the 1926 Plan of Space Exploration as developed by Tsiolkovsky (www.informatics.org/museum/tsiol.html).

Homer Hickam, Friday, 4-13-12

http://archived.thespaceshow.com/shows/1751-BWB-2012-04-13.mp3

Guest:  Homer Hickam.  Topics:  We discussed his new book “Crater” & how he developed the technologies & systems to make living on the Moon credible.  You are invited to comment, ask questions, & discuss the Space Show program/guest(s) on the Space Show blog, https://thespaceshow.wordpress.com. Comments, questions, & any discussion must be relevant & 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 Homer Hickam to the program to discuss his new book “Crater” & his new Kindle book, “Paco: The Cat Who Meowed in Space.”  You can buy each book from Amazon using these special URLs & Amazon will make a contribution to The Space Show/OGLF:  For “Crater,” use www.amazon.com/Crater-Helium-3-Novel-Homer-Hickam/dp/1595546642/ref=onegiantlea20.  For “Paco,” use www.amazon.com/Paco-Meowed-Kindle-Single-ebook/dp/B007K1OC6K/ref=onegiantlea20.  Homer explained that Crater (set 120 years in the future) was a teenage orphan working to mine HE3 which was sent back to Earth as Earth desperately needed it for fusion energy.  While telling us about his book, we learned that Homer created solutions to many of the challenges to living on the Moon.  For example, microgravity & radiation – listen to how he solved the problems.  Muscle deterioration? He solved that one too.  Transportation back & forth between Earth & the Moon?  That one too.  Spacesuits, the use of one atmosphere, all sorts of other challenges to our having a lunar settlement have a solution to make the Crater story credible.  As you will hear, not only does Homer go into detail about the storyline, but he focused on the solutions & this makes the story both believable & credible.  Issues such as lunar dust, children on the Moon, even pregnancy, well, there is a solution.  Food & water too.  We did go off the topic of his books to ask about space policy.  As you will hear, Homer thinks the Moon will be developed by entrepreneurs for commercial value.  He sees companies such as Space X changing the game for our space policy & does not see government space programs being what they once were though development of needed infrastructure is part of what government can & should do.  The lunar transportation systems he talked about will be private commercial businesses.  When asked how he came up with solutions to problems encountered when living on the Moon, he talked about a study he did in the 1990s which is on his website, www.homerhickam.com. Homer was asked why the Moon & not Mars.  Don’t miss his response to this listener question. We also talked about the space programs for other countries such as China. Homer then told how he envisioned the world to be 120 years in the future. As you will hear, countries have broken up into smaller, more manageable nations, including the United States.  The world is not as we know it today.  Toward the end of the first segment, Homer was asked about the difference in times from when he grew up in W. Virginia to today given the listener said his son could not even fly an Estes rocket in their city. Part of his reply stressed the need to join rocket clubs today.  Before the break, we talked about insitu resources, water, food, law, & justice on the Moon.

During our short second segment, Homer was asked about strip mining on the Moon & he had much to say about it. Don’t miss this discussion.  He was also asked about other uses for the Moon besides HE3 including solar, radio telescopes, & manufacturing.  As the show ended, he commented on the need to have better political leadership to lead us forward in space development. He also had more to say about slime mold which plays an important part in his book.
