We welcomed David Steerman Scott & Richard Jurek to the show to discuss their excellent new book, "Marketing the Moon: The Selling of the Apollo Lunar Program" (www.marketingthemoon.com). This was a 75 minute show without a break. We started out talking about how the two authors met & decided to collaborate in writing this book. As you will hear, both are marketing experts and when they met they wondered why the marketing side of the Apollo program had not been written about so they decided to do it. Not only is their book & this discussion about lessons learned, possible extrapolation points, & seldom if never heard history, it offers answers to many questions asked of guests & listeners on TSS but this time we got some answers that make sense. Our guests talked about the massive NASA PR & outreach campaign launched to sell the early space program, plus the work the contractors did on their own with media kits, training the press how to handle the science/engineering to be able to explain it to us & more. We talked about the time period, the U.S. at the time of Apollo, television then and now as well as newspapers & print media then & now. Our guests also talked about the distribution today for PR & information which is radically different from the days of Apollo. Both our guests described important attributes for a space program to work. Some of these included a quest story, defined mission goals, targeted goals & timelines, the need to avoid mission design creep, the need for a global imperative, & a WHY for the mission that drives the mission. Examples were provided including the Red Bull Stratos jump which did all of the above & the VSE under President Bush which came up lacking. Listeners asked lots of email questions including asking if a mission could sell itself with demonstrated engineering, technology, and science. The answer was doubtful but listen to what our guests had to say about this issue. We talked about missed opportunities over time as great opportunities for audacious and daring projects seldom come around. They talked about a missed opportunity at the time of 9/11 by going for the Iraq War instead of an Apollo like world game changing program, even one not involved with space. Later in our discussion, our guests provided us with one of the best reasons for going back to the Moon & doing space programs, especially for human spaceflight. I'm referring to Apollo changing the world forever for the best by spawning youngsters to create Microsoft, Apple, Intel, etc. Read the rest of this summary @ www.thespaceshow.com or http://thespaceshow.wordpress.com.

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. Please post any comments/questions you might have on The Space Show blog.

During the first segment of our 1 hour 29 minute program, Brett introduced us to the concept of space burial and in particular the new start-up, Elysium Space Burial. He went over their services and their marketing to both customers in the U.S. as well as Japan where cremation is the common thing. He gave us some interesting funeral industry statistics for both the U.S. and Japan and we learned that they have a Japanese language website, http://jp.elysiumspace.com. We talked about their launch services which he said would likely be with SpaceX or Orbital but in any event they only plan to use a U.S. launcher. Also, they do not at this time have plans for suborbital launches, only orbital launches and from the established launch sites. We talked about their expansion plans to BLEO services and learned of their mobile app which you can get from their website for Apple and Droid products. The company has seven employees, some of which are part time. In the second segment, I asked Brett how his company differed from the competition. He talked about the personalized services they provide plus their intended use of dedicated spacecraft. He also talked about the media and PR received by the firm in their first year of operations. Listeners asked for his process when working with a completed kit, and if their memorial services were non-denominational which they are. Blair emailed asking about their plans to use smaller launchers such as Microlaunchers. Brett said not yet but possibly down the road. Alex asked about using government launches over private mission launches. Others wanted to know more about their future plans and what countries they had their eyes as future markets. India was mentioned as one such company. When asked for their 5-7 year plan, Brett spoke about driving the costs down and launching 5-7 memorial flights per year. Near the end, a listener asked about green funerals and Pooley emails us asking about their plans for a fast decaying LEO. Also in this segment and in the conclusion, Brett offered a special deal for Space Show listeners so don't miss it. Please put comments/questions on The Space Show blog above.

Our Open Lines discussion started with my providing scheduling announcements as there will be no live shows the week of April 21 due to medical issues I need to address. Rather than play specific OLDIE programs which I usually do in the absence of a live show, I suggested that listeners go through the archives and listen to an archived show or two of their choice, compare what you heard on the archived show to similar issues in space today, then call our next special Open Lines show which will probably be Sunday, April 27 and share your thoughts and perspectives with us. For this Open Lines program, I also suggested a few discussion topics including Russia's Putin saying "We are coming to the Moon FOREVER" as reported in the MailOnline on April 11, 2014. You can read the article I discussed on the show at www.dailymail.co.uk/news/article-2602291/We-coming-Moon-FOREVER-Russia-sets-plans-conquer-colonise-space-including-permanent-manned-moon-base.html. It reported Russia wanted to go to the Moon, colonize it and stay there as Russia was viewing the Moon as its own permanent colony along with similar colonies it wants to establish on Mars and asteroids. Putin also mentioned Russia was in a race to the Moon. TO READ THE BALANCE OF THIS SUMMMARY, PLEASE VISIT EITHER WWW.THESPACESHOW.COM OR HTTP://THESPACESHOW.WORDPRESS.COM. This summary review was too long for the Gigadial space but you can read it in full per above. Thank you.

Please remember to buy this book through the OGLF/The Space Show Amazon portal so Amazon will contribute to The Space Show. Our Amazon instructions are in every archive summary and on each Space Show blog entry. During the first segment of our 90 minute discussion, Dr. Moltz told us why he wrote the book which was to address orbital crowding, possible conflict in space and to bring these issues and others to the attention of the general public as space impacts everyone everyday. A major topic for our discussion was space debris. Using this field as an example, Dr. Moltz made a very strong case for rules of the road, space traffic control issues, and responsible behavior by both governments and the private sector. We talked about entrepreneurs and private groups resisting a more regulated environment and he made the case for the need for cooperation to avoid conflicts. Early in his book, he outlined three significant points of view regarding the debate over space policy, ranging from conflict & the military use of space was inevitable so prepare for it to avoiding problems by piecemeal global engagement to increasing the use of international space projects through international governance. Dr. Moltz received many email questions challenging a regulated environment and the need for more controls on space businesses and operations. We talked about the cubesat technology and growth of the industry, the lack of registration, & as the industry grows, possible crowding problems. We also discussed the U.N. treaties that seem to cover what we were talking about so why the need for more agreements & regulations? In our second segment, we continued our human spaceflight discussion from the end of the first segment, plus we looked at space in other countries. We mostly focused on China, India, Iran, and North Korea among others. We talked about large scale industries that may develop over time such as SSP. GPS was an example, then a listener asked about cyberwarfare & the impact on space policy. Toward the end of the program, I asked about space interest among students at the Naval Postgraduate School. Students are very interested space and the subjects discussed in Clay's book and on today's show. Please post your comments/questions on TSS blog. You can reach Dr. Moltz through me.

This will help me bring better programming to the audience. We welcomed Bob Zimmerman back to the program for a discussion on a variety of space new and policy topics. During our first segment of our 2 hour 5 minute show, we talked about the U.S. sanctions against Russia for their behavior in the Crimea/Ukrainian region and the instructions to NASA to halt all activity with Russia on space issues other than what is related to the ISS. As Bob pointed out about 98% of space activity with Russia is ISS oriented so Bob said the sanctions did not amount to much. He then talked policy, the idea that Russia wants its own space station and breaking the ISS agreement. He said nations break agreements like this all the time and cited our pulling of the EXOMARS agreements with Europe as an example. He then told us about the PLATO multi optical telescope being built in Europe for looking at exoplanets. Next, listeners wanted to talk with him about the upcoming Falcon 9 launch and reusability. Bob had much to say on the launch, the delay, and first stage reusability. Philip emailed in from New Brunswick about the Russians largely sticking to themselves on station. Bob spoke to cultural difference with the Russians, language issues, and said that they tended to their own experiments as we do our experiments. He also said the Russians need to keep the ISS going and need us to stay with it. Virgin Galactic was discussed and Bob went over some the test, engine, and personnel changes in recent times. A listener emailed in about a Fox News Show over the past few weeks in which space made up part of the show. The Fox News panel seemed to be traditional in nature and felt our space program was a mess and declining. Bob spoke to his usual position in that he does not want any government space program. Tony called from Seattle to talk more about reusability & the problems with the SpaceX first effort on this on a prior launch. In the second segment, we mentioned the role of satellites in looking for Flight 370 and Bob talked about rescuing people and such programs in general. We asked for suggestions for new space topics for discussion and Bob himself suggested underground oceans on Enceladus & LADEE's results from the Moon for lunar dust experiments. We talked about the emerging cubesat industry, Dream Chaser, then near the end of the show, I asked Bob for an update on the White Nose bat fungus problem. We talked about the possibility of space being a topic in the 2014 congressional elections and Bob spent lots of time telling us all why SLS was no good. Visit his website, www.behindtheblack.com. Please post comments/questions on The Space Show blog above. You can reach Bob through me or his email address at the end of his bio.

We welcomed Randa and Rod Milliron back to the program to discuss their successful March 29, 2014 Common Propulsion Module Test Vehicle launch plus updates on the overall Interorbital Systems (IOS) s progress. In our fist segment of this 91 minute program, we mainly talked about their recent launch which Randa and Rod took us through step by step. Lots of questions came in via email by listeners and later on by phone calls. Some of the questions focused on the PR given the John Frusicante’s (Red Hot Chili Peppers) album ENCLOSURE (The Record Collection, Malibu) payload which was incorrectly described by the non-space industry media. We also talked about IOS getting a Class 3 waiver for the launch & what that process involved. Rod took us through technical and design aspects for the rocket and we also talked about the larger Neptune Modular Rocket System that the company is developing for orbital spaceflight. Also of interest to listeners were the IOS TubeSat and CubeSat do it yourself kits which include a launch when the kit is completed. As we learned, IOS is rapidly filling up their third planned launch for these kits. Another point of interest was their upcoming launch for this summer which will be a guided launch for the first time. Both Randa and Rod talked about being vertically integrated and making and doing all the parts and engineering in house. One email listener asked for their plans to go suborbital and then orbital. Another listener inquired about the do it yourself satellite kits pricing & ease of building. Before the segment ended, we talked about the IOS plans for ocean launch. Neb called in from Bosnia to talk about the IOS success throughout Europe and the positive impact of the musical payload. In the second segment, we talked about IOS ITAR requirements, the number of payloads per rocket, the ongoing plans for a lunar mission, nuclear propulsion, and their guidance system. Neb call again from Bosnia to talk about how IOS was inspiring people around the world. Randa gave us an update on the plans for Olav Zipser to skydive from a rocket, then Doug emailed in to inquire about how the diameter of the common propulsion module was determined. Randa & Rod also talked about their future plans for visiting Venus. Don't miss this discussion. Please post your comments/questions on TSS blog above.

Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://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.

This will help me bring better programming to the audience. We welcomed Dr. Behrokh Khoshnevis to the program to discuss 3D Printing and Contour Crafting which Dr. Khoshnevis invented. For more information, visit www.contourcrafting.org, www.craft-usc.com, and www.bkhoshnevis.com. In our first segment of our 1 hour 45 minute discussion, Professor Khoshnevis provided us with an overview of 3D printing, its history, strengths and weaknesses. He also took us through the three main methods of fabrication and their subsets. We talked about state of the art manufacturing processes and several times during our discussion he said 3D printing would never replace modern manufacturing which would always develop along the cutting edge in advance of 3D printing techniques, processes, and speed. He talked about the materials being used for the printing and the strengths and weaknesses of them. We began talking about 3D printing in aerospace and he talked specifically about "layering." During this segment, he told us how he started looking for new processes for printing large structures which is what contour crafting is so good at doing. He explained contour crafting in construction and he identified multiple specific uses for it. Since he had already talked about how slow the process was with 3D printing, he made a point of saying that contour crafting could be hundreds of time faster than just regular 3D printing. In talking about aerospace, he explained why logistics can be a problem. Later in the segment, we talked about the significant power needs even in space, plus the high use of water. Because of the water, he told us about substitute methods that made it possible to not use water. He said meaningful structures could be made such as habs. He fielded several listener questions, including some that asked about 3D printing being a magic solution, especially for space applications. In the second segment, our guest was asked about the impact of microgravity and radiation on contour crafting and 3D printing. Doug called in and talked about inflatable structures rather than construction of structures. Our guest offered Doug important observations about the inflatable structures. We also asked about the high demand for water by these printing processes. Behrokh said that water usage might be a problem but by using sulfur and insitu resources, there would be alternatives to water. A listener asked him if a spacesuit could be printed. Our guest said not likely giving the reasons for that thinking. We talked about 3D printing of food, medical supplies & medicines. As we were ending, I asked the professor for the level of interest his students show in the contour crafting and 3D printing fields. His response might surprise you. Post your comments/questions on The Space Show blog above. You can email our guest through his websites or me.
