Dr. Paul Hardersen, Monday, 1-24-11 (16.21MB; download) --
Guest: Dr. Paul Hardersen. Topics: The North Dakota Space Studies Department and UND Observatory. 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. Dr. Hardersen returned to The Space Show to update us on the UND Observatory and the new fundraising campaign for the observatory system. Visit http://observatory.space.edu/default.aspx for additional information on the observatory system. Also visit http://observatory.space.edu/donations/default.aspx for information on their new fund raising program, $120K in 12 Months: Bringing the stars to North Dakota. Dr. Hardersen described the observatory facilities and talked about the type of telescopes used, how students can access and control the telescopes over the internet from member colleges, and how the buildings cannot be heated due to the impact of heat on the lenses. As a result of this, the observatory is usually closed during most of the winter. Dr. Hardersen explained how students use the observatory and how it fits into the Space Studies curriculum for both on campus and distance students. This is a short half our discussion so if you want more information about the observatory or the Space Studies Program, please email Paul at hardersen@space.edu. You can also post a comment or question on The Space Blog URL listed above.

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. Selected by: David Livingston [ stations ], Mon, 24 Jan 2011 01:40:13 UTC

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.

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. Selected by: David Livingston [ stations ], Mon, 17 Jan 2011 04:29:29 UTC

Dr. John S. Lewis, Friday, 1-14-11 (44.02MB; download) -- Guest: Dr. John S. Lewis. Topics: China's space program, He3, fusion, the Moon, and more. 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. In our fist segment, Dr. Lewis began discussing the Chinese space program which was discussed in depth during the entire interview. One of the questions asked him was about China's possible membership in the ISS partnership. Don't miss his response but also note what he said about the Khrushchev Principle. In response to other listener questions, Dr. Lewis described the difference between urban and rural China as to space awareness and education. There were also listener questions pertaining to "Mining The Sky: Untold Riches from the Asteroids, Comets, and Planets," the famous book written by our guest. By the way, this book is available on the OGLF Amazon partners page. If you buy it using www.amazon.com/dp/0201328194?tag=onegialeafou-20, Amazon will make a contribution to OGLF/The Space Show. Listener Chris called in from Argentina and asked Dr. Lewis about faith and religion and how it had impacted his science and work. Our second segment started with a discussion on space resources and finding a market. For example, Dr. Lewis said we would not be returning hydrocarbons to Earth. Later, he talked about the Chinese program being a great source of national pride as was the Apollo program to the United States. Our discussion move to He3 on the Moon but as you will hear, we talked about it quite a bit during the balance of the interview. Dr. Lewis talked about He3 on the Moon, the outer planets, and fielded a question about it on Mars. During this discussion, he did say without fusion energy, He3 did not have that much value. That said, Dr. Lewis reported on the status of developing fusion energy using the ITER as an example and said progress was being made. Another thing Dr. Lewis pointed out was that to extract one ton of He3 on the Moon, you need to process 100 million tons of lunar regolith. As you will hear him say, we need to develop a very small test program to see if we can even process He3 from the regolith. Note what he said about the harsh conditions and environment that one will have to work in for both men and equipment to process He3. Toward the end of the second segment, a listener asked him for a comparison of the Indian lunar program with the Chinese program. Our third segment started with a question about He3 on Mars. You will hear Dr. Lewis explain why this is a non-starter. Charles called in to discuss the D-T model for fusion. Mark inquired some more about NEOs and co-orbitals and asked Dr. Lewis for his favorites for development. The Japanese program was discussed with Dr. Lewis saying it was a very serious program. The 2011 Chinese lunar schedule was mentioned with the approaching launch of Shenzhou VIII. Toward the end of our program, Dr. Lewis told us about his upcoming science fiction books, a few of which will be released this year. Check out www.johnslewis.com for more information about the topics we discussed today and the works and blog of Dr. Lewis. If you have comments or questions for Dr. John Lewis, please post them on The Space Show blog. You can also post comments and questions for Dr. Lewis on his website.

Mary Roach, Tuesday, 1-11-11 (32.35MB; download) -- Guest: Mary Roach. Topics: Her book "Stiff" and a discussion of human cadaver scientific testing and its history with human spaceflight. 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. Noted author Mary Roach returned to the show to discuss her book "Stiff: The Curious Lives of Human Cadavers." This book is available on the One Giant Leap Foundation Amazon Partners page at www.amazon.com/dp/0393324826?tag=onegialeafou-20. When you purchase the book through OGLF, Amazon contributes to The Space Show. During this one hour program with Ms. Roach, we not only talked about the scientific impact and usage of human cadavers, we talked about cadaver usage in the space program. Though limited, such research was used in Apollo capsule splashdown tests and in other areas. As you will hear, Mary, with her customary wit and humor, takes us through the various ways cadavers are used for scientific study and the impact these tests have had on safety that impacts all of us. Some of the chapters of Stiff that we focused on had to do with head research as well as what was learned from the TWA 800 plane accident. We were able to extrapolate much of this discussion to human spaceflight safety but as you will hear, for a variety of reasons, some of the safety studies, especially for race cars and automobile accidents don't transfer well to space because of need for severe restraint for safety which is not practical or possible for spaceflight passengers. One of the issues Mary told us about was the concept for how to return a body to Earth from Mars or another space location. Drawing on the Swedish burial system known as Promession to reduce the mass of the body, Mary described the plan on the show. You can read comments about this at http://deathreferencedesk.org/2010/09/12/prepare-for-death-and-follow-me-into-outer-space. Ms. Roach identified the system as the Body Back System. Our topics for tonight's show are seldom talked about let alone on a program primarily dealing with space issues. Despite this, the subject is interesting and has relevance for space issues. If you have questions or comments for Mary Roach, please post them on the blog URL above. You can email Mary through me at drspace@thespaceshow.com.

Dr. George Sowers, Monday, 1-10-11 (44.03MB; download) -- Guest: Dr. George Sowers. Topics: EELV for human rating, commercial space topics, space policy issues. 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. In our first segment, Dr. Sowers began with an assessment and description of the Atlas rocket & its role over the years, then moving to discussions with Bigelow and commercial crew with NASA re CCDEV. We talked about what would be required for human rating an EELV and then we talked about the testing program that would be used for such the new systems. Dr. Sowers explained this process in some detail so make sure you listen carefully to this segment. We talked about launches from Vandenberg as well as the Cape to the ISS and even beyond the ISS. I asked Dr. Sowers about the launch price increases I have been mentioning on air that were mentioned at the recent AGU conference in San Francisco. He explained this matter in some detailed. Here, we talked about the NASA Launch Services (NLS) and the new NLS 2. As you will hear, the price increase story is correct but Dr. Sowers cleared up lots of confusion surrounding the issue. As the segment ended, we talked about launch service being treated as a commodity. Don't miss what Dr. Sowers said about this. Our second segment started with a more detailed description of what Dr. Sowers meant by referencing our industrial base. As you will hear, this is a concise and excellent overview of our aerospace industry as of now. I then asked Dr. Sowers for his take on what constituted commercial space. We had a comprehensive discussion about this, including the types of contracts used, the nature of the customer, space markets, and more. A listener suggested that SpaceX was more commercial than ULA because of some misunderstandings of the origins of EELV so don't miss what Dr. Sowers had to say about this matter as ULA and EELV are absolutely commercial. Another topic that came up was the perceived but incorrect competition with Orion and CCDEV. CCDEV is really about going to LEO and the ISS. Orion is being built for beyond LEO and the ISS. He said it was a false competition. We then talked about the private sector capabilities for doing safe and reliable human spaceflight to the ISS. Not a problem but listen to the discussion. Later in the segment, space tourism came up as a subject followed by a listener asking about reusability. Toward the end of the program, I asked about new commercial markets and business opportunities arising form the commercial space policy debate in 2010. I wanted to know if our guest was seeing new opportunities coming to the forefront, even if just in the Power Point format. Here, Dr. Sowers referred back to Bigelow as the most real near-term opportunity. Please post your comments and questions on The Space Show Blog URL above. If you want to send a comment or question to our guest, please do so through me at drspace@thespaceshow.com. Selected by: David Livingston [ stations ], Tue, 11 Jan 2011 19:03:35 UTC

Open Lines, Sunday, 1-9-11 (70.86MB; download) -- Guest: Open Lines with Dr. David Livingston. Topics: Space policy, commercial space, the Moon's core, north pole movement, heavy lift and more. 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. This Open Lines program was about 135 minutes divided into two segments. I put forth several discussion topic suggestions including the Discovery Shuttle tank cracks, the Chinese stealth fighter, NASA's research suggesting that the Moon has an Earth-like core, layoffs taking place in the Huntsville area, issues regarding The Space Show Blog, and issues of civility with the space policy debate and stakeholders. Our first caller Sal wanted to talk about the movement of the North Pole and other related matters. Sal was followed by Kelly talking about Orion, commercial crew, and space markets. These discussions filled up the first segment. In the second segment, Marshall called in from Dallas to respond to the comments by Sal regarding the north pole. Marshall brought in the use of GPS for better navigation and suggested GPS was negating the three definitions commonly used for the north pole. Later, Tim in Huntsville called in to respond to my comment about the possible need for a destination with a fixed time table to have an effective civil space policy. Tim was advocating cheap access to space and I asked him how to achieve that goal. We then had a discussion about markets versus costs, the Field of Dreams scenario, and what we both might expect in the way of the space program moving toward low cost space access. Our discussion included our perspectives on emerging markets coming to the forefront as a result of the space policy and commercial space debate we saw take place last year. John from Atlanta then dialed in to talk some more about heavy lift and I kept asking him what it would be used for and we got into a discussion about possible funding cuts, the authorization bill ,and what the appropriators might do. We talked about Orion, Dragon, and what Boeing might do for a commercial crewed capsule. Toward the end of the program, we took another call from Kelly to discuss Congress and its micromanagement of NASA through the budget. Kelly thinks Congress may micromanage the funding going to NASA and I am more of the school that NASA will figure out its priorities within its budget and make the allocations. We also talked some more about the Chinese stealth fighter as well as stealth planes from other countries. Kelly thought that this international push toward stealth fighters might result in the U.S. going for a new fighter aircraft and rebuilding that segment of our industry. Our final call was from Sal to clarify what he was saying about black holes at the center of the Earth. If you have a question or comment, please post it on the blog. If you want to send a note to any of the callers, send it to me and I will forward it to the person of your choice. Selected by: David Livingston [ stations ], Mon, 10 Jan 2011 04:53:56 UTC

Jim Lewis, Friday, 1-7-11 (44.48MB; download) -- Guest: Jim Lewis. Topics: Deep Space Communications and Virtual Teleportation, a new business venture. 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. Check www.deepspacecom.net for more information. You can read more about virtual teleportation at http://news.yahoo.com/s/prweb/20101209/bs_prweb/prweb4878054_1. In our first segment, Jim introduced us to the Deep Space Communication Network he set up to send messages to space, including many Space Show messages over the years. He then discussed their new project, virtual teleportation. There is an EBay auction for the project so if interested, search EBay for Virtual Teleportation into Space. Jim took us through the process of being able to virtually teleport a person into space, including all the medical, historical, and psychological profiling done to make sure the DNA is supplemented by sufficient data to reassemble the person by an advanced intelligence, assuming such ET intelligence exists. He also mentioned that the data was being securely stored here on Earth for 30 years. Jim explained the make up of the $40,000 price for this service as it does entail many participants to make sure the message can be sent to deep space. Listeners asked Jim about family packages, doing this for pets, and more. He said they were open and flexible as this was very new for them too. It is being test marketed using an EBay auction. Charles called in to ask about transmissions using laser diode rather than RF and this brought up a discussion of transmitting off Earth. As you will hear, since the transmissions use RF, there is not much to be gained by doing it off Earth. We also talked about the power range of the transmissions, the fact that they travel about 4-5 light years, and that its estimated that it will take about twenty minutes to transmit the virtual teleportation data. In our second segment, we inquired about possible ITAR regulations and ideas for broadening the market appeal for those interested in doing virtual teleportation. We then switched topics for a health condition of the space coast since Jim is located at the Cape. He gave us a good summary of what was going on along the Space Coast, including shuttle, Falcon 9, commercial space, and layoffs. Later in the segment, Alice asked if there was anyway to get feedback once the signal was transmitted. Unfortunately, once its transmitted, there is no feedback or information as to what happens to it. I asked Jim about his space documentary TV making and if that business was changing or declining given the condition of the economy and the space industry. As you will hear, there appears to be a lessening of interest among the public and the networks for space programming. If you have questions or comments about the virtual teleportation, deep space messages, or anything else discussed, please post them on The Space Show blog. You can also email Jim Lewis at jlewis@cciflorida.com. Selected by: David Livingston [ stations ], Sat, 08 Jan 2011 18:11:41 UTC

Douglas Messier, Tuesday, 1-4-11 (48.95MB; download) -- Guest: Douglas Messier. Topics: ParabolicArc.com, space news reporting, space 201 and 2011 events. 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. For more information, visit www.parabolicarc.com. In our first segment, Doug briefly outlined some of his news sources and what he does to be able to report extremely current and often ground breaking news. After this discussion, he was asked for his choice of the best story for 2010 and he talked about the runway dedication for Spaceport America and Branson's flight to the runway from Las Cruces to open the runway. You will both enjoy and appreciate this story. We then talked about the new governor of New Mexico and possible spaceport audits and personnel changes. Another topic was Obamaspace and Doug said he thought it was about 80% right on. While a fan of commercial and NewSpace, he said it still suffers from limited commercial flight and simply too few flights, often requiring members of congress to have a leap of faith in the industry. Space workforce jobs then entered our discussion and since Doug is also in California, I spent some time asking him about the California national as well as state legislative officials and their views on space and their support of the California space industry. As you will hear, its not like what goes on in other states with a stronger human spaceflight presence such as Florida, Alabama, and Texas. Doug then talked about the shifts taking place in the industry and geographically due to the rise in commercial space activity. In the second segment, we talked about the NASA CRuSR program, COTS, and CCDEV. Doug was asked about the likelihood of 2011 being the year for a SpaceX IPO. You won't want to miss what he said about that. Space tourism came up and Doug was asked to tell us how the industry has changed over the past twenty years that he has been covering space news and exploration topics. During this discussion, Doug summarized what many of the space tourism suborbital companies were doing and their progress plus expectations for this new year. In our third segment, we talked about writing scripts for Star Trek as Doug had pitched a few scripts to several of the Star Trek franchise TV shows. He shared his experiences with us and explained the process for doing this. He then told us about visiting several of the Star Trek sets and meeting a few of the cast members from the different programs. Later in this segment, we spent additional time talking about CCDEV, NASA's commercial crew development program. We then moved on to talking about EELV human rating conversions and Doug said he had a post on the subject on his blog at www.parabolicarc.com/?s=human+rating+certification. Toward the end of the program, Brenda asked about changes over the past two decades in the public perception of space development and exploration. At the end of the show, Doug listed three areas of expectations for grand events for 2011. Listen and see if you agree with him. If you have a comment or question for Doug Messier, please post it on the blog URL above. You can email him at 21stcenturycomm@gmail.com.
