Add this to another station Michael Belfiore, Friday, 2-4-11 (53.78MB; download) -- Guest: Michael Belfiore. Topics: Commercial space, technology and space, space innovation for the future. Please note that you are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Our discussion with Michael started off with Michael talking about technology innovation and specifically energy. I asked him about SSP and then we honed in on NASA. He said this time was a big turning point for NASA as it transitioned away from operating government launch vehicles to buying the services from commercial companies. Michael suggested much was on the table in this process and it was still not clear where space policy would end up. A listener asked him about a recent NY Times article about likely funding cuts for commercial crew and comments about the absence of a commercial market. You can read this article at www.nytimes.com/2011/02/01/science/space/01private.html?partner=rss&emc=rss. Michael was also asked about returning to the Moon and the need for destinations in our space policy. We started the second segment with a continued discussion on the European Code of Conduct for Outer Space and the likely objections to it by NewSpace on the grounds it may restrict commercial space. We talked about the rules of the road for orderly space commerce, collision avoidance, debris mitigation, etc. We then moved on to human rating EELVs, Orion, Bigelow Aerospace, and SpaceX. Later, Michael was asked if NASA should evolve into a more DARPA like organization. Michael spent some time with us discussing this issue. We then talked about possible FY 11 NASA budget cuts and the progress being made by many of the NewSpace companies. Michael promoted his blog which is at www.michaelbelfiore.com. We talked about space conferences and the important conferences for NewSpace. If you have questions or comments for Michael Belfiore, please post them on The Space Show Blog URL above. You can also email Michael at michael@michaelbelfiore.com.

Add this to another station Berin Szoka, Tuesday, 2-1-11 (45.50MB; download) -- Guest: Berin Szoka. Topics: Internet freedom and regulation with parallels to commercial space development. Please note that you are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. We welcomed back Berin Szoka to discuss the state of internet freedom, related issues, and the parallels with commercial space development. We started our first long segment talking about the new book published by TechFreedom (http://techfreedom.org) , a new technology policy think tank, titled "The Next Digital Decade: Essays On The Future Of The Internet." You can read or download it at http://nextdigitaldecade.com. Berin began this discussion by going through the book's introduction which can be found at http://nextdigitaldecade.com/summary. As you will hear, the book focuses on freedom and thought leadership by having brought together 26 thought leaders with expertise in internet law, philosophy, policy, and economics, writing 31 essays addressing the important issues surrounding the internet, its freedom, possible regulation, and even government control. Some of the issues talked about during this segment included the use of the internet kill switch (Egypt) and the pending congressional power giving a U.S. president similar types of authority. Berin talked about this pending U.S. legislation in some detail. In addition to talking about the cyber security bill, he provided us with information regarding the different schools of thought concerning support for technology. Later, he was asked about think tanks in general and we learned that the structure of a U.S. think tank was somewhat unique when compared to think tanks in other countries. Listen for this explanation. Another listener asked for clarification of net neutrality. Berin provided us with a detailed analysis of net neutrality, not just for the U.S. but how it was now playing out in Canada with the Canadian version of this concept. This took us to a discussion of what is referred to as regulatory capture. Berin said that net neutrality was the worst for innovation so don't miss this important discussion. We also talked about common carriage and how its being applied to the internet. In our shorter second segment, Berin told us about the upcoming NewSpace Conference which will be at NASA Ames July 28-31, 2011. Visit http://newspace2011.spacefrontier.org. As you will hear, Berin will likely have an internet freedom panel at the conference to discuss the very issues we have been discussing tonight, plus much more. I suggested to Berin that there also be a workshop to teach those interested how best to use social media tools to promote the NewSpace, internet freedom, or another cause. Stay tuned for details on this as I am sure I will do some NewSpace PR programming as we get closer to the conference date. As we moved toward the end of the program, we talked about the untapped potential of the internet and its power for helping to establish cultural change, something that many in the space community are also working hard to do. During the program, Berin suggested several books and authors for reading on the issues discussed tonight. Though these books are not listed on the OGLF Amazon partners webpage, if you intend on buying them, let me know and I will give you a special Amazon/OGLF code to use when ordering the book so that Amazon will contribute to The Space Show.

Topics: GTO/GEO potential satellite collisions and their impact, space and STEM educational outreach in Israel. Please note that you are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. During our first segment, we talked with Mr. Pariente about the Ilan Ramon International Space Conference in Israel and the paper delivered by our guest regarding GEO-GTO possible satellite collisions and the impact of such a collision on the GEO belts as well as on society. This entire segment is dedicated to discussing this potential problem which as you will hear, has potentially very serious consequences for us all should such a collision take place. In our second segment, we talked about space education and related programs in Israel. Our guest described the nano satellite program in Israel and the space engineering programs both in high school and college. These are bending metal programs, not theory. We learned that municipalities fund these programs, especially at the high school level through the three year course to launch of the student nano satellite. Listeners asked lots of questions about the high school program, including the gender mix of the students and the motivation behind the students engaging in these programs. We talked about space as an inspiring and motivating tool in Israel and learned that it was, along with technology in general. Later in the segment, listeners asked about space tourism interests in Israel and then we attempted to compare the Israeli educational programs with those here in the U.S. We started the third segment with an email from the African Space Institute concerning the interest from Israeli students in space and also what caused the increase in girls having an interest in satellite development in Israel. Another listener asked about ITAR issues in Israel and the Israeli GPS system under development. We concluded our discussion with a look at the probabilities of a GEO-GTO satellite collision.

Add this to another station Dwight Steven-Boniecki, Sunday, 1-30-11 (46.76MB; download) -- Guest: Dwight Steven-Boniecki. Topics: Lunar based television and technology. Please note that you are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. We welcomed Dwight Steven-Boniecki to discuss his new Apogee book, "Live TV From the Moon." You can buy this book from the OGLF website and Amazon will make a contribution to The Space Show. Please use this URL when ordering: www.amazon.com/dp/1926592166?tag=onegialeafou-20. During our first segment, Dwight told us about his early interest in the lunar and space program when he was a young boy in Australia. His story advanced to San Diego to working in the film and TV industry and to being very curious as to how some of the Apollo lunar TV footage was made, especially when Neal Armstrong came down the ladder to the lunar surface the first time and we could see it all on live TV. During this first segment, not only does out guest tell how much of the footage and TV video was done, he talked about the help he received in researching the subject for his book. He described the early technology of doing color using the Sequential Color Converter, color wheels in the cameras, and the cameras by Westinghouse and RCA. In the second segment, we talked about the astronaut training involved to work the cameras and broadcast the TV signal back to Earth. Listeners asked about the costs for the TV equipment, training and broacast, and we talked about the debate within NASA as to broadcasting live TV from the Moon. Later in the segment, our guest received a few questions about the Hasselblad still cameras used on the Moon and we talked about their thermal protection modifications. John in Atlanta called in to talk about the Transformer movie conspiracy and the missing 21 minutes and our guest even told us how the Transformer movie came up with the 21 minute gap! We started the third segment with a listener question about the famous golf shot on the Moon and how that was broadcast for TV. Listeners asked about the potential for a lunar reality TV show and as you will hear, Dwight was not too optimistic that such a program would be a sustainable financial success. Later in the segment we talked about Skylab and the use of multiple cameras on the station. Dwight also talked about the camera mounted on the Lunar Rover. As the program neared its end, we talked about going from analog to digital and the system of cameras and color broadcasts on the Space Shuttle through the 90's and then later. At the end of the segment, I asked about depth perception on the lunar surface as shows by a series of photographs in the book. Dwight had much to say about lunar depth perception or the absence of it so don't miss this discussion. Our guest directed us to the website www.livetfromthemoon.com as well as www.apollohoax.net. If you want to contact our guest, you can do so through www.apollohoax.net/contact or you can send your comment or question to me and I will forward it to him.

Add this to another station Todd Neff, Friday, 1-28-11 (44.26MB; download) -- Guest: Todd Neff. Topics: Ball Aerospace, Deep Impact, additional Discovery Class Missions. Please note that you are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. We welcomed Todd Neff to the program to discuss his new book, "From Jars To The Stars: How Ball Came to Build a Comet-Hunting Machine." This book will be on the One Giant Leap Foundation (OGLF) Amazon partners page and if you buy it using the OGLF link, Amazon makes a contribution to OGLF/The Space Show. Please see www.onegiantleapfoundation.org/books. We began our program by remembering the 25th anniversary of the Challenger accident. We then moved to topic of the day, the Deep Impact Mission, which was the subject of the new book written by our guest. Todd told us why he wanted to investigate and report on this story with Ball Aerospace and as you will hear, Todd provided us with an interesting and seldom discussed history of not only Deep Impact, but also solar pointing and more. For those of you who like space history, you will really appreciate this discussion. Todd starts around 1948 and takes us up to Deep Impact which was launched in 2005. During our second segment, Todd continued with the Ball Aerospace history and he focused on the Discovery Class Missions. He then explained why comets were such interesting targets and how Ball determined that doing Discovery Class Missions was the "sweet spot" for the company. Toward the end of this segment, we talked about the success of Deep Impact and how it was measured for the benefit of Ball Aerospace. In the third segment, we talked about offshoots of the various programs that Ball was involved in and Todd mentioned Digital Globe and Kepler along with other Discovery Class Missions. During the program listeners asked questions about the history we were discussing. Near the end of the program, Todd was asked for the method used to actually hit Temple 1. Also near the end of the program, we talked about mission creep, cost overruns, and the NASA culture. If you have comments or questions you can also email Todd Neff at todd@toddneff.com.

Add this to another station Declan O'Donnell, Tuesday, 1-25-11 (51.98MB; download) -- Guest: Declan O’Donnell. Topics: United Societies In Space (USIS), commercial space, treaty law, changing the law. Please note that you are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Note that this is Space Show number 1,500! We welcomed back Declan O’Donnell for updates with the USIS organization, The Buzz Aldrin Library, and commercial space legal issues based on the United Nations Treaties. We started our first segment with Declan telling us about the recent Boulder conference that both Buzz and he attended that addressed suborbital flight and suborbital flight training for the people wanting to participate in space tourism. He said there appears to be lots of people interested in the space experience as well as going to space and that so far from his perspective, money was not much of a roadblock, if at all. Declan then switched to discussing USIS. In this discussion, he put for the idea of the Space Development Authority as the way to accomplish the best legal regime to promote, manage, and develop commercial space. He cited two examples for the authority model, the TVA and the Chunnel Authority. Declan suggested that we create the Space Development Authority which would eventually be managed and funded separately from governments. At this point in our discussion, Declan talked about potential legal challenges to commercial space based on the benefit sharing language in the U.N. treaties, specifically in the 1967 Outer Space Treaty (OST). Declan told us about his having recently spoken about potential legal challenges to commercial space at a recent NASA meeting in Hawaii. Listen to what he had to say about this meeting and the reaction of those in attendance. This is an important discussion, listen carefully, and post comments to the blog as to what you think about the potential problem Declan points out. As we started our second segment, our guest went on to say that Article 11 of the Moon Treaty provided the solution to this problem. In addition to the Moon Treaty clause, Declan talked about the procedure for changing the law using the IAF to validate the concept that space can be inhabited and developed for people now and his IAF suggestion and procedure offered the legal proof needed based on the Moon Treaty clause. Listeners asked Declan why we don’t just withdraw from the OST and since the U.S. has not signed the Moon Treaty, why is it even applicable to us. Don’t miss his important answers to these questions. Other issues and listener questions that came up dealt with legal challenges, what courts would have jurisdiction and here, you will hear Declan say that any federal court in the U.S. would have jurisdiction and that such a case if and when it comes up will eventually go to the Supreme Court because of its wide ranging importance. Near the end of the program, Declan described a new USIS program underway with Boy Scout packs, the Aerospace Venture Club. We also talked about the forthcoming issue of the USIS publication, Space Governance. As you will hear, I offered to send to interested listeners a recent USIS email containing many of the documents Declan discussed during the show. If you are interested in this email, please send your request to drspace@thespaceshow.com. If you have comments or questions for Declan O’Donnell, please post them on The Space Show Blog per the above URL. Declan also invited listeners to join in with USIS. His email address is djopc@qwestoffice.net. Declan can also be reached at 1-800-633-2828. His fax number is 1-303-666-8595.

Add this to another station CLASSROOM Introduction, Sunday, 1-23-11 (37.25MB; download) -- Guests: Classroom: Dr. David Livingston, Dr. John Jurist, Dr. Jim Logan. Topics: The Space Show Classroom introduction for 2011. Please note that you are invited to comment, ask questions, and discuss the Space Show Classroom program/guest(s) on the Space Show Classroom blog,http://spaceshowclassroom.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show Classroom programming. The Space Show Classroom is back and this one hour program was our introduction to the 2011 semester. Co-hosts Jim and John and I went through our suggested course outline which I will finalize upon my return from Grand Forks and post on the Classroom blog as soon as possible. While we have a full agenda as you will hear, we are open to and we welcome your course and topic suggestions, as well as suggestions for possible expert guests for the Classroom programs. Today, listeners asked us some detailed questions about radiation, solar flares, and a few of our suggested discussion topics, but this introductory program was more about letting everyone know that the Classroom has returned and what we will most probably be covering during the year., We also introduced a few new rules for the Classroom. For example, we will not be using the toll free number for the Classroom this season. There are a few reasons for this including the need for more phone lines when we do point and counterpoint discussions which we want to do more often. In addition, we all thought that many of the listener phone calls last year took us off the Classroom main topic. Remember, the Classroom is different from regular Space Show programs in that we do a two hour simulated graduate school course discussion and we need to stay focused and on topic just as in a real classroom. The Classroom has its own blog per the URL above. All Classroom shows are archived on The Space Show website, Gigadial for podcasting, and on the Classroom blog. They are not archived on the regular Space Show blog. The Classroom blog is moderated and we do not post any comments or material not directly on point with Classroom programs and discussions. If you want to contact the Classroom co-hosts, all of us have our email addresses listed on the blog. Mine of course is drspace@thespaceshow.com. One other Classroom rule we used last year and it seemed to work fine so it will be used this year as well is that all emails and comments about the programs or for the guests directed to me need to be posted on The Classroom Blog so everyone can see them and participate in the discussion. If you do not post your comment yourself, I will post it on the blog under your name. For the Classroom, we want to expand our discussions to as many markets and interested people as possible and one of the best ways to do that is to make sure that we have a variety of points of view on the blog along with quality discussions. Finally, most all Classroom programs will be on a Sunday or Tuesday and just as we did last year, every Classroom program on the schedule, in the newsletters, and on archives will have “Classroom” at the beginning so these programs can be easily identified.. Thank you for participating in the 2011 Space Show Classroom series of programs.

Add this to another station Marc Millis, Monday, 1-17-11 (44.69MB; download) -- Guest: Marc Millis. Topics: Breakthrough propulsion, advanced technology development, interstellar travel, science and engineering development. Please note that you are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. We welcomed Marc Millis back to the program to discuss some of his new papers and developments dealing with advanced propulsion for space travel. Marc has two new papers to read: 1) "Progress In Revolutionary Propulsion Physics" at http://arxiv.org/abs/1101.1063. 2) "Energy, incessant obsolescence, and the first interstellar missions" at http://arxiv.org/abs/1101.1066. Be sure to visit the Tau Zero Foundation website at www.centauri-dreams.org/?page_id=2118. In our first segment, Marc talked about his new interstellar paper and that based on energy requirements, it might take between one and two centuries to be able to realize interstellar travel. He explained his theory based on energy but also talked about other ways of forecasting when interstellar travel might become a reality with each of the other ways suggesting similar time lines. Marc said that being able to realize interstellar travel was essential and was a survival imperative for humanity. We then talked about various projects that are pushing the technology window including the Japanese Project Ikaros and the Tau Zero Foundation Project Icarus. We talked about nuclear propulsion and undiscovered physics. As you will hear, Mr. Millis said the key to advancing technology was being able to ask the right question. We explored his comment in some detail. At the end of this segment, Marc talked about cultural trends in the space field and that often organizations start to develop outside the main one to fill a void. This discussion came about because he was asked if NASA should be doing breakthrough propulsion research and development and was it appropriate to spend public money on such projects. We started our second segment with a listener asking how to determine if an idea is a crackpot idea or not. Mark provided us with a range of factors to use so this is a discussion you will want to listen to and maybe even take some notes. He also told us about the famous paper, "Unskilled and Unaware of It" which as you will hear, appears to be applicable to the crackpot issue. Later in this segment, he was asked if we had the skills and abilities to back engineer an interstellar vehicle that was here on Earth. You might be surprised by Marc's answer so again, listen carefully to what he had to say. At the end of the segment, he was asked why Moore's Law cannot be applied to technology advancement and propulsion physics. Don't miss his response to this question. In the third segment, he talked about the DARPA/Ames study, the One Hundred Year Starship Study. Later, he was asked about timelines for propulsion development as compared for space projects like going to the Moon, a NEO, etc. As you will hear, we should not confuse the timeline required for a mission as compared to the timeline required for technology development. If you have comments or questions for Marc Millis, post them on The Space Show blog. You can also use the contact section on his website and reference The Space Show.

Add this to another station Dr. Paul Spudis, Tony Lavoie, Sunday, 1-16-11 (48.74MB; download) -- Guests: Dr. Paul Spudis; Tony Lavoie. Topics: Their paper titled "Mission and Implementation of an Affordable Lunar Return." Please note that you are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. We welcomed back Dr. Paul Spudis and as a first time guest, Tony Lavoie to discuss their recently published paper, "Mission and Implementation of an Affordable Lunar Return." You can download their paper here: http://blogs.airspacemag.com/moon/2010/12/can-we-afford-to-return-to-the-moon and www.spudislunarresources.com/Papers/Affordable_Lunar_Base.pdf. I urge you to read their paper before commenting on the blog or sending either guest an email. While our program unfolded in three segments, our entire discussion was focused on their program for returning to the Moon. Dr. Spudis started us out in the first segment with a history going back to Augustine when he was not satisfied with the conclusions from the committee and set out with Tony to see if they could develop a lunar return architecture that would work and fall within the NASA budget. During the first segment, our guests addressed the commercial potential of their suggested program as well as the incremental approach the program draws upon. Toward the end of the segment, we talked about timelines, both for the robotic and site exploratory missions, then followed by the human missions. We also talked about the use of telerobotics for this program as the Moon is close enough to allow for this while a NEO or Mars mission would incur substantial time delays rendering it difficult to use teleoperated robotics. In our second segment, Tony expanded the time line topic and carried it out to around year seven. We also talked about ways to assure long term congressional financing and project support. We took several listener questions including one from Marshall regarding a possible liquid core for the Moon. Spike both emailed and called in with questions about the paper, while there were several additional questions about the use of lunar water for fuel as well as for humans. Toward the end of this active listener give and take with our two guests, Jerry asked about the Moon having an increased value due to recent exploration and discoveries. You do not want to miss what our guests had to say about this. In fact, as you will hear from our guests, this increased lunar value with the discovery of water and more provides a significant part of the rational and the economics to return to the Moon. At the end of this segment, our guests fielded a heavy lift question. As you will hear, the paper suggests moderate heavy lift at approximately 65 metric tons. While the analysis was not made, the suspicion was that without heavy lift the mission costs would be higher. In our third segment, we continued with listener questions and calls on a range of subjects related to the paper. John inquired about reusability and engines. Tim inquired about nuclear propulsion & a liquid oxygen and aluminum powder as the propellant. I then asked Paul and Tony for their implementation plan for their program. We concluded the program with a discussion of the value of this plan and returning to the Moon for us to become space fairing, not just to quickly go to a destination and return as we did with Apollo. The plan is about making Cis-lunar space affordable and routine so we can continue expanding our presence in space. We talked about space development as a wealth building tool and investing in space development and not treating it as an expense. Post your comments and questions for our guests on The Space Show blog at the URL above. Dr. Spudis has a website, www.spudislunarresources.com & a blog @ http://blogs.airspacemag.com/moon. Guest email addresses are on the title page of their paper.
