Al Zaehringer replay from 2005, Friday, 11-14-08 (84.61MB; download) -- Guest: Alfred Zaehringer was the guest for this replay program, first on Jan. 4, 2005 and then again on April 12, 2005. During the first segment of the show from January 2005, Mr. Zaehringer focused on rocket economics, explaining in detail why it is difficult and maybe impossible to substantially lower the cost of getting to LEO, the Moon, or anywhere in space with a chemical rocket. Mr. Zaehringer afforded Space Show listeners a unique opportunity to hear a different perspective, one steeped in science, engineering, and rocket know-how. We discussed commonly perceived lunar, LEO, and other space development projects, all of which fell to the sword of launch and rocket economics as explained by Alfred Zaehringer. Alfred did say that we need to be focusing on using space for transportation, i.e. going from one city to another or even another country by using rockets to save time, and also on space tourism. These ventures need to be done by the private sector, not NASA. When asked what he would do as the NASA Administrator, he said he would close some of the offices, carry out lots of consolidation, end the planetary science and exploration program by turning it over to universities, and stress space tourism and space transportation. He would also focus on building, flying, and testing vehicles. When asked for his thoughts about the Bush space policy initiative, he stated it was more political than substantive and that we do not have the technology, the vehicles, the know-how, the experience, nor the cash to take us back to the Moon. He does favor a heavy lift vehicle, but separate from shuttle components and infrastructure. Alfred covered many other topics ranging from space property rights to the space elevator and more. You will certainly want to hear what he has to say and give some thought to his comments and perspectives. He knows rocket science and economics so one must carefully consider the information he shared with us tonight. During the second segment of this program from the April 12, 2005 show, Mr. Zaehringer again focused on rocket economics during the program, explaining in detail why it is difficult and maybe impossible to substantially lower the cost of getting to LEO, the Moon, or anywhere in space using chemical rockets. In response to his earlier appearance on the program Jan. 4th of 2005, Mr. Zaehringer was asked a series of follow up questions exploring possibilities for reducing launch costs to the next lower level, $1,000 per pound to LEO. We discussed new and lighter materials, rocket motor design and pump changes, fuel, sustained high flight rates, range fees, insurance costs, and more. Mr. Zaehringer remained convinced that the price is not going to be that low with chemical rockets and he very clearly stated why, citing the realities of physics and the rocket equation which cannot be ignored. For those of you interested in this subject, in seeing commercial businesses open up in space, on the Moon, or on near-Earth objects, listen to what Al Zaehringer has to say. He believes that dealing with reality is much better than trying to ignore it.

Marianne Dyson, Tuesday, 11-11-08 (44.14MB; download) -- Guest: Marianne Dyson was our guest for this Space Show program as we discussed her role in the early days of NASA as one of the first ten female flight controllers. Since 2008 marks 50 years of the United States space program, there is much to learn by becoming familiar with our space history. Ms. Dyson worked on the first five shuttle flights and shared stories about these flights, plus what it was like working on them at the time. Not only do we learn insights about NASA in these early years of the shuttle regarding crews, the shuttle, and female employees, but we get an insider look at the type of problems that took place on the early missions and ways in which problems were solved. We also learned how the shuttle was tested first with a crew of two, then up to four, then five, and finally a full crew of seven astronauts. You will certainly want to hear what Marianne has to say about this part of our space history. There is laughter as well as fear. In fact, she told us that STS-5 was the scariest for her so listen to her story. Think back to Nov. 11, 1982, 26 years ago from this show, as the times were quite different then, the support was different and as you will hear, the technology was different. Listen through the perspective of the times of the day, 1982! Marianne shared many stories with us about employment back then and some issues that came up regarding the women employees. She mentioned the first space walk and STS-7 with the first woman astronaut on board. Marianne Dyson has a book that you can check out, "Space And Astronomy." Visit http://www.mariannedyson.com/publications.html for information on this and other books she has written. Her website is http://www.mariannedyson.com and if you want to send her a comment or question, you can do through the contact link on her website or emailing mariannedyson@yahoo.com.

Drs. Buckey, Cartreine, & Rose, Monday, 11-11-08 (43.11MB; download) -- Guests: Dr. James Cartreine, Dr. Jay Buckey, and Dr. Raphael Rose were the guests for this special Space Show program focusing on the NSBRI "Self-Guided Depression Treatment on Long-Duration Spaceflights." We began this discussion with our guests explaining the purpose and mechanics of the Self-Guided Depression Treatment computer program for use by the astronauts. Along with listener questions, we went into detail about this self-help program which will complete testing and studies by mid-2009 and then be put into service by the space program and possibly into general public distribution. We also talked about conflict management and stress management, how astronauts would use the program, its confidential nature, and how it could supplement more traditional therapy while being a true self-help, effective program. We talked about the application for the program to other sectors of the community, not just the space and astronaut community. One listener brought up the Eliza computer therapy program from the 60s, the effectiveness of self-help programs for addressing depression, especially when counselling was not available. The new program being designed is a multi-media program receiving input from 29 current and former astronauts. It can be used here on Earth and also in route to a space destination such as Mars. Depression and its impact on long duration spaceflight was explored in detail, including complications from other human factors issues such as radiation and bone loss. For more information on the NSBRI program, please email info@www.nsbri.org or you can send your comments and questions to me at drspace@thespaceshow.com and I will forward them to the doctor of your choice or the National Space Biomedical Research Institute.

Veronica Ann Zabala-Aliberto, Sunday, 11-9-08 (40.64MB; download) -- Guest: Veronica Ann Zabala-Aliberto, a senior undergraduate student in the School of Earth and Space Exploration at Arizona State University, was our guest for today's Space Show program. Our discussion started by having Veronica tell us the origins of her interest in space and how she became so involved and committed as she has and you will learn during this program. In fact, please visit her comprehensive experience website at http://www.linkedin.com/in/veronicaannzabalaaliberto to learn more about her space involvement and experience. We next discussed the LRO and the special LRO Narrow Angle Camera. Veronica explained how students can work on the project team. She even laid out a path for students if their school is not officially involved in a project such as this one that they may want to work on. Other topics discussed included Second Life, a virtual world one can access on their computer. We even discussed teaching university classes in Second Life. Veronica also told us about the Mars Desert Research Station in Southern Utah which is sponsored and managed by the Mars Society (http://www.marssociety.org). Another topic of interest was being politically involved to support and push for continued space exploration. Listen to what Veronica had to say about this and the phone tree and other tools available to those interested in this type of space involvement. Toward the end of the program, Veronica provided us with a glimpse of ISDC 2009 in Orlando, Florida and we talked about some of the programming and work she does for 4Frontiers Corporation. You can contact Veronica Ann Zabala-Aliberto with your comments and questions by using veronica.zabala@asu.edu .

Norman Gerstein, Friday, 11-7-08 (72.74MB; download) -- Guest: Norman J. Gerstein was the guest for this special Space Show program. Mr. Gerstein was deeply involved in Rover/NERVA and we discussed these programs in detail. He was part of the KIWI-TNT team and involved in the cleanup by picking up the debris with a wheelbarrow and tongs. Norm described these programs in detail along with the nuclear rocket which we compared to chemical rockets. Norm made it very clear that one needs a mission to do these programs. Another way of saying it, is to make sure there is a need. Since there was no need (no mission), the programs were cancelled. Today, a nuclear rocket exists for a manned mission to Mars, but listen to what he says about the probability of such a mission anytime soon. One way to not need the nuclear rocket would be to go to Mars by launching from the Moon as the nuclear rocket would not be advantageous for use in going to the Moon. You will find this discussion most interesting. Our discussion also led us to Norm's analysis and conclusions regarding the SSTO and its feasibility. Norm also suggested that a nuclear rocket might be launched from a suborbital position but this was not something that was highly sought after. Later in the show, we talked about the need or the mission for manned space flight. Norm was in agreement with many other Space Show guests this year in saying it was hard to make the case for manned space flight and the silver bullet for manned space flight remains elusive at best. Again, a discussion you will not want to miss. We talked about radiation, nuclear power plant accidents, waste storage and reprocessing, hybrid autos, electric cars, space solar power, and solving our energy crisis as a priority. Norm told us about his preference for vehicles using natural gas plus other ideas he had suggested over the years. We also discussed Norm's idea for a 200,000 ton manufacturing press. The Russians have a 75,000 ton press, so this would clearly be the largest. He thinks it could be a private sector business and would capture large scale manufacturing work from around the world. Reactor pressure containers and other high-end uses would benefit from a single sheet without welds. After listening to this discussion, tell us what you think. Many other topics were discussed including due diligence, running numbers for a comprehensive due diligence analysis of a project of interest. You can send your comments or questions to Mr. Norman Gerstein by using ngerstein@comcast.net.

Open Lines, Tuesday, 11-4-08 (56.07MB; download) -- Guest: Dr. David Livingston hosted an Open Lines Space Show program for this election night special program. The first segment featured my personal thoughts, opinions, and analysis regarding space solar power (SSP). If you want to know what I really think about SSP, listen to what I have to say about it. As this was election night, we talked some with the listeners about the election, about how space might fair with the new administration and Congress, and what U.S. space policy might be like in coming years. Several callers shared their views with us regarding SSP as well as space elevator, NASA, civil space, humans to Mars, NewSpace, and more. One listener sent in an email about the next possible NASA administrator. Toward the end of the program, we discussed space policy, nuclear weapons, and a host of related subjects. These are discussions you will want to hear even if you want to question or challenge the caller or me. If you do have questions for any of the callers, send them to me and I will forward them to the caller you want to receive your input. Please use drspace@thespaceshow.com for all questions and comments for this show. On behalf of all listeners, we sincerely wish President-elect Obama and Vice President-elect Biden a good term in office for all of America. We have our share of problems and we will require skilled, competent, and wise leadership over the coming months and years, not just for space, but for all matters facing our nation.

Paul Breed, Monday, 11-3-08 (42.27MB; download) -- Guest: Paul Breed of Unreasonable Rockets was the guest for this Space Show program. Please visit his blog http://unreasonablerocket.blogspot.com/ for more information. We started our discussion with Paul talking about the history of Unreasonable Rocket as to how he started it, how he got his son interested in working with him building rockets, and even why he named the company as he did. We also talked about his efforts to compete in the Lunar Lander Challenge over the years up to the current year and why he did not enter this year. You will find his story and experiences to be most interesting. We also talked about rocket testing and the facilities he used. Paul told us where the facilities are that he uses, he described them and the cooperative effort in building and maintaining them, and other facilities close by. In fact, we discussed some of the alt.space and armature rocketry infighting that resulted in the two rocket test centers. Paul's operation is very transparent and he even put all his AST papers, permits, and filings on the website. In response to his disclosures about his rocket and AST, he was asked about ITAR issues since one does not know who may or may not be seeing or reading this material. Paul said he posts everything in public domain and textbooks or other books used are all public domain so he does not have ITAR issues. We also discussed engineering and science education, out-of-the-box thinking and behavior, the necessity, or not, of having an advanced graduate degree, such as a doctorate, or more hands-on experience building and operating things. This is a very important part of our discussion, so listen carefully to what Paul has to say about this subject as well as our engineering education in general in the country. There is much to this interview that you will want to hear and I am sure that Paul Breed will be back on The Space Show as his work and projects continue. If you have a question or comment for Paul, please email him at Pau@rasdoc.com. You will have to comply with his spam filter ID process if you want to engage Paul Breed with a question or discussion.

Dr. Sam Dinkin, Sunday, 11-2-08 (42.70MB; download) -- Guest: Dr. Sam Dinkin was the guest for this Space Show program. We started our Q&A with Sam with an update on his start-up, Space Shot. Here, Sam took us through the game, its current status, and then, in response to a listener question, he did a "lessons learned" from starting this business. This is a must hear discussion and is applicable to more than just Space Shot. We also talked about space in the future. Sam mentioned that, in his opinion, we would likely develop the oceans first, including aquaculture and then develop habitable aerostats. On the latter point, he received several listener questions about the physics and engineering needed to have a functioning aerostat habitation at about 100,000 feet. Listen to what he said and see what you think regarding this futuristic vision. We also talked about future launch prices and how they might come down in price and over what time. Given that Sam is a PhD economist, we turned our attention to the concerns we all have about our economy, the global economy, and what it all means for space. In addition, I asked Sam for likely economic influences with our presidential candidates and if we could expect major differences from either. Listen to his analysis. You will find it interesting. Dr. Dinkin said he was most optimistic for the future of space, but one of the things he learned from his Space Shot experience was that there really was no hurry to settling space and that would likely unfold on its own time frame, much the way settlers settled the New World from Europe and the West. If you have a follow up question or comment for Dr. Sam Dinkin, please send it to sam@dinkin.com.

Brian Hanley, Friday, 10-31-08 (75.66MB; download) -- Guest: Brian Hanley was the guest for this Space Show program addressing the issue of bioterrorism. Our far ranging discussion covered not just the subject of bioterrorism and its agents such as anthrax, but how the health care system and public health are primary biodefense. As you will hear, natural disease is a far greater killer than bioterrorism has yet been, and a greater killer than wars also. Brian explained in some detail the risks we face because of our current public health system. We discussed the anthrax attacks, anthrax as a weapon, and listeners asked about likely targets: metropolitan cities, medium sized cities, or small town America. Listen to what he had to say about this. Mr. Hanley discussed bioterrorism attacks in recent years to put them in perspective. One listener asked him if he ever thought our world would be free of this threat or it was here to stay. Sad to say, here to stay was the response. I believe you will find his history of disease and its impact on society to be most interesting, also, the weak points for spreading disease in society now. Toward the end of the program, Brian introduced us to what he calls the Potemkin Perimeter. The former Russian Minister, Grigori Potemkin's Villages were not real but were designed to impress the Empress during the Crimean War. Brian compares this to the legislative and DOJ efforts regulate research work and prosecute offenders in order to impress the public that "action is being taken". He warns that these are counterproductive. Listen to his analysis and see what you think. You can contact Brian Hanley with your comments and questions using the email address, brian.hanley@ieee.org.

Dr. Gregory Berns, Tuesday, 10-28-08 (43.54MB; download) -- Guest: Dr. Gregory Berns, chair of Neuroeconomics and professor of psychiatry and behavioral sciences at Emory University in Atlanta, was the guest for this Space Show program to talk about his new book, " iconoclast: A neuroscientist reveals how to think differently." Parts of Dr. Bern's research on this subject for his book was conducted by studying the developing NewSpace community. In fact, Chapter Seven is titled "Private Spaceflight-A Case Study of Iconoclasts Working Together." Here, he uses space tourism, rocketry, and spaceflight participants to illustrate specific cases of iconoclasts. Not only will you want to hear this discussion, this book, in particular this chapter, are must-reads for The Space Show audience. In our discussion with Greg, we talk about not only what an iconoclast is, but the character makeup needed for one to be an iconoclast. He defines an iconoclast as a person who does something that others say can't be done and then he goes on to say three functions are necessary for the person to demonstrate or validate being an iconoclast: perception, fear response or management/containment, and social intelligence. Each of these characteristics are discussed during this show, but another element is needed as illustrated by the case of Howard Armstrong who has the credit for developing FM radio and more. This additional factor is the ability to sell the idea to others. Listen to the Armstrong story followed by a comparison with Bill Gates. See what you think of these two people as iconoclasts. We had several callers and we talked about being different, not with the program or movement, something that kids are teased about, but that adults in the developing space community are accused of all too frequently. Iconoclasts are different, they are not usually "belongers" to anything, so showing them in the different light portrayed by Dr. Bern can be reassuring as was mentioned by our listeners. This was a comprehensive discussion of this subject, both as applied to space businessmen and women, but also in other business, artistic, and development communities. If you have a question or comment for Dr. Gregory Bern, please send it to me at drspace@thespaceshow.com and I will forward it to our guest.
