Dr. Allan J. McDonald, Wednesday, 6-20-12 (50.41MB; download) -- Guest: Dr. Allan J. McDonald. Topics: "Truth, Lies and O-rings: Inside the Space Shuttle Challenger Disaster." You are invited to comment, ask questions, & discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, & any discussion must be relevant & applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed Dr. Allan McDonald to the program to discuss the Challenger accident from the inside. Visit his website for more important information, http://ethicskeynotespeaker.com. If you order his book from Amazon with the following URL, Amazon will make a donation to The Space Show/OGLF: www.amazon.com/Truth-Lies-O-Rings-Challenger-Disaster/dp/0813041937/ref=onegiantlea20. During our fist segment, Dr. McDonald provided the background on why he wrote the book & his information sources. He mentioned some of the difficulties he faced getting it published & his decision to work with the famous historian & author, Dr. James Hanson. During the remaining part of this segment, he went over the real story of what happened before, during, & after the Challenger accident. He told us about the three part conference call the night before to determine if Challenger should be launched, the requirement by NASA management for the engineers to prove that what they were saying about the o-rings & cold temperatures would cause failure rather than asserting it was unsafe to do the launch given the prevailing temperatures & winds. We learned about NASA management intimidation & compromises eventually made by Thiokol to support NASA management contrary to the engineering data that existed. Dr. McDonald explained what was behind launch "go fever" & the most probable source for it. Our guest talked at great length about the temperature parameters, the evidence they had from recovered SRBs leading to severe cold weather safety concerns, all of which NASA management ignored. We also learned about extremely cold temperatures, 6-7 degrees at the launch site, & that it was not reported by NASA personnel the morning of the launch. We fielded several listener emails & phone calls. Some questioned NASA management about their engineering knowledge & competence. We also talked about the lack of accountability for decision making within NASA at the time. In the second segment, questions about liquid rocket engines as compared to solids were answered, supported by facts. For those of you who disagree with Dr. McDonald on this issue, why not post questions for him on the blog? Later I asked about making the SRBs without segments & if they were segmented only to please the Utah delegation back in the day. Our guest had much to say on this, talked about the very large un-segmented SRBs that were made & ground tested near the Cape, & he explained several of the trade decisions that must be evaluated were we to go to one large booster without segments. Dr. McDonald explained his redesign & the fix implemented after the accident. He also talked about the oversight involved in the redesign process & why it was nearly impossible to come up with an approved & effective fix for the o-ring problem. We talked some about the Challenger litigation, then our guest was asked for the new SRB cold weather operating parameters. In his closing comments, he pointed out the lessons to be learned with one of the main points being that many people against the launch for solid engineering reasons never spoke out given they were intimidated by NASA management wanting to do the launch no matter what. He said that it was an ethical obligation to speak out in these matters. People must not remain silent & that was & is today an essential lesson to be learned from Challenger. Please post your comments/questions on The Space Show blog. Selected by: David Livingston [ stations ], Thu, 21 Jun 2012 16:20:47 UTC

Walter Cunningham, Tuesday, 6-19-12 (52.09MB; download) -- Guest: Walter Cunningham. Topics: An inside view of the American space program from Apollo to today. You are invited to comment, ask questions, & discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, & any discussion must be relevant & applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed Walt Cunningham to discuss our space program from Apollo through today's developing commercial space industry. For more information, visit his website, www.waltercuningham.com. You can buy "The All-American Boys: An Insider's Look At The U.S. Space Program" from Amazon & they will make a contribution to The Space Show/OGLF if you use this URL: www.amazon.com/All-American-Boys-Walter-Cunningham/dp/1876963247/ref=onegiantlea20. I started the discussion by asking Walt about his perspective on Apollo 7 today, 44 years later. Walt had some interesting things to say about perspective, especially over the past 10-20 years as compared to when he actually carried out the mission. A few times during our discussion, questions came up about the so called "mutiny" with the crew & NASA ground control so listen to how Walt described what was mostly a non-event despite media & blog reports to the contrary. He did talk about Wally Schirra, his head cold & the Actifed commercials, but there was far more to the mission & to the significance of Apollo 7. Dr. Jurist asked about the ride on a Saturn 1B, professors & experiences while both were at UCLA. We discussed risk regarding his ride on the Saturn 1B. Walt had much to say about risk during the Apollo era as compared to now. We extrapolated from this discussion to Columbia's foam issues. We talked about commercial space. Walt suggested that today's commercial space efforts were not purely commercial given government funding & missions. He also said that retiring the shuttle when we did was a big mistake. He then took us through a cost analysis process to illustrate that space is & always will be costly. At the end of the first segment, one way trips to Mars & reality TV show funding were mentioned. In the second segment, Terry called with questions about Von Braun. Walt had high praise & much to say about Von Braun & his experiences with him. Commercial space came up again & I asked him about asteroid mining. He did not think it would be a good investment & talked about the need to pay attention to the laws of physics. We talked about He3 on the Moon, fusion energy possibilities & more. I read an email from a London listener asking about the Apollo rocket & mission sounds on Apollo 7. We talked some more about the problems on board Apollo 7, this time regarding Wally & the TV broadcast delay & the wearing of the newly designed helmets during reentry. Walt talked about climate change & global warming, urging people to do their own research & examine the data rather than believing what people had to say regardless of their position. John in Atlanta called in about global warming & said that there was no practical mitigation strategy. Our guest shared what he perceived to be the true motivation of global warming extremists. John also talked about having built a next gen space shuttle from the old space shuttle to avoid retiring it or having to build an entirely new & very costly program. Walt supported that idea but history proved otherwise. Toward the end we discussed the pros & cons of international cooperation & competition, Ares 1 as a safe rocket for HSF, & the cost of the ISS being more due to international cooperation. Our final topic was risk versus reckless behavior & the difference between the two. If you have comments/questions, please post them on The Space Show blog.

Rick Searfoss (Col. USAF RET), Monday, 6-18-12 (51.97MB; download) -- Guest: Rick Searfoss (Col., USAF, RET.). Topics: Rocket Flight, XCOR, Lynx, flight safety, leadership. 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. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed back to The Space Show Rick Searfoss to discuss spaceflight flying, XCOR Aerospace, the Lynx, and much more. You can learn more about Rick Searfoss by visiting his website, www.astronautspeaker.com. For more about the Lynx and XCOR, visit www.xcor.com. We started our discussion with an overview of a successful test flight program. During this discussion, our guest made it clear that flight tests are supposed to detect the unknown and to catch problems in time for them to be fixed prior to surfacing during commercial operations. The test pilot is prepared for the unknown and this is why he later said that future XCOR pilots would need to have U.S. military test pilot school experience along with their military flight experience. Also, the testing starts out very slow and escalates based on the progress and analysis of the tests. One crawls before one runs, so to speak. I asked him to compare a spaceship test flight program to information I had on a new Boeing 747-8 Intercontinental Jetliner that Boeing was putting through 600 flight hours of flight tests (www.examiner.com/article/new-boeing-747-8-intercontinental-maiden-flight). Don't miss this discussion, its interesting, important, & relevant. Col. Searfoss received an email from Jeremy asking about humans riding on solid rocket boosters (SRB) and the safety in doing that. This resulted in another interesting discussion. We then talked about piston pump technology, suborbital flight, turbo pumps, and the XCOR program working with ULA regarding hydrogen pumps. I asked Rick to describe the Lynx flight from the passenger perspective. Doug wanted to know about the first flight timeline for later this year and then Christine wrote in asking if the Lynx cockpit would have dual controls similar to an airplane. A question came in about the Chinese rendezvous & docking per their current mission & Rick's take on the process given his space shuttle pilot experience. Rick talked about this with the shuttle in some detail. In our second segment, Terry called in to ask about the XCOR flight software. As you will hear, XCOR flight software means humans. Listen to what he had to say about this, including issues with space shuttle software. Our guest then talked more about the flight readiness process including the Technical Review Board and Safety Review Board process. Other topics discussed included citizen science on board the Lynx, ITAR issues, additional Lynx pilot qualifications, and defense dept. applications for Lynx and the suborbital industry. Lee called in to ask about an evolution to an orbital vehicle, other questions came in regarding runway requirements, passenger height & weight requirements, and spaceports. Near the end of our discussion, we talked about an emergency exit from the Lynx, spacesuits and bailout. Also discussed throughout the program were suggestions for the passenger to better prepare for his/her flight. If you have comments/questions, please post them on The Space Show blog.

Sir Martin Rees, Sunday, 6-17-12 (46.39MB; download) -- Guest: Sir Martin Rees. Topics: Science in our society, space development, political leadership, education & more. 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. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed back Sir Martin Rees to discuss his new book, "From Here To Infinity: A Vision For The Future Of Science." Please remember that if you order this book from Amazon using www.amazon.com/Here-Infinity-Vision-Future-Science/dp/0393063070/ref=onegiantlea20, Amazon will make a contribution to The Space Show/One Giant Leap Foundation. Lord Rees started our discussion by talking about the amazing things we have learned about the cosmos in a very short period of time. He also explained that this new book is based on a series of lectures he did with BBC Radio. We also talked about science reporting in the media but we focused on teacher issues, both in the UK and the U.S. Another topic covered in his book was religion and science conflicts. An example cited was creationism. We also talked about space as a spiritual experience. We then talked about commercial space development with companies such as SpaceX, the high risk averseness of NASA, and the fact that private companies can take on more risks. Lord Rees expressed the view that for human spaceflight for sure, we will see more and more of it being done by the private sector. Our guest was asked about science on the ISS & he said it was hard to justify the ISS on the grounds of science. Jack called in to ask talk about the outstanding history programs on the Royal Society website, http://royalsociety.org/Podcasts-of-Library-events. He also mentioned famous sci-fi author Neal Stephenson, www.amazon.com/Quicksilver-The-Baroque-Cycle-Vol/dp/0380977427. Jack's call was followed by John in Atlanta who talked about spirituality, consciousness, religion and the work of Roger Penrose. This led to an interesting discussion about the search for the unified theory and the difference in perspective with cosmology and fundamental physics. Our next topic was in response to a note from Fred about political leadership and space/science issues. Out last topic of the segment dealt with the Kepler Space Telescope (KST) and the search for extraterrestrial life. We asked questions about the impact on cultures were life off Earth discovered. Sir Martin had much to say about this subject. In our second segment, we started out talking about science fiction. Sir Martin is fascinated by the ideas in science fiction so don't miss his comments on this subject. Harold in Los Angeles asked if we might be slowing down in our rate of discovery of new science & space information. This is another terrific discussion. We then talked about the Earth's population growth and the intellectual shift to Asia away from the west. Lord Rees talked about the need to balance out science and development in the under developed regions, focusing on Africa for example Later in the segment, we talked about bringing space resources back to Earth & our guest said the economics of doing this are still up in the air. Space settlement and returning to the Moon came up as did private missions to Mars and the asteroids. Our guest suggested that one way Mars missions might be possible in the future, but the probability of doing it near term & funding such a mission remains somewhat low at this time. Our guest also mentioned genetic modification for those that do settle off Earth but thought the ethics of doing it on Earth would make it unlikely to happen here. If you have comments/questions for Sir Martin Rees, please post them on The Space Show blog. Selected by: David Livingston [ stations ], Mon, 18 Jun 2012 16:12:24 UTC

Dr. Madhu Thangalevu, Frankie Sharpe, Friday, 6-15-12 (50.40MB; download) -- Guests: Dr. Madhu Thangalevu, Frankie Sharpe. Topics: USC Moon Studio space & architectural project planning and design. 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. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed back Professor Madhu Thangalevu who was joined by Frankie Sharpe, one of the architectural graduate students in the USC Moon Studio program that just ended. Dr. Thangalevu started out by telling us about the USC School of Architecture program and their space studio classes including the Moon Studio, Space Studio, and the program with the engineering department for the Engineering Space Concepts Studio. Madhu then introduced us to Frankie Sharpe who talked about his lunar tourism project he did for the Moon Studio graduate class. You can see some of his slides for his project at http://cargocollective.com/frankiesharpedesign/Tour-the-Moon and http://uscmoonstudio.blogspot.com. In the process of Frankie telling us about his lunar tourism model, he talked about the learning process, the need to address engineering, cost, and human factors for his project, the solutions he developed for dealing with the new NASA guidelines for protecting and visiting the historical Apollo landing sites and more. You will see how he creatively used holographs for the visitor to experience the actual lunar landings, how radiation issues were resolved, and much more. I asked Frankie a series of questions about interest in his space work in the regular architectural firms has and is working for & you might be surprised by what he had to say. You will also find it interesting that prior to being given the opportunity to enroll in the Moon Studio, space was not on his graduate school agenda. In our second segment, Dr. Thangalevu talked about other USC space studio workshops and then we talked about space policy and the proper role for space in policy and our lives. Professor Thangalevu talked about large global space projects that involve people everywhere such as planetary defense and climate change research. We also talked about U.S. leadership in global space projects. One of his suggestions was to consider that it might be time for a U.S. Department of Space to deal with these issues but he did say a paradigm shift had to take place for space to be fully realized. He then introduced us to the cosmopolitanism concept. This led us to an interesting discussion about the space "elders" passing the torch to the younger generations for their leadership forward. During this discussion, we talked about the need to fail, to push to the design & function limits to failure so that something new & better comes from the lessons learned in the failure. Our last topics included suborbital space, producing nuclear fuel for propulsion on orbit, hydrogen from algae on orbit, a lunar super computer connected to the aging Deep Space Network, and space & spirituality. Please post your comments/questions on The Space Show blog. If you want to email our guests, do so through me & I will forward your email.

Open Lines, Tuesday, 6-12-12 (72.17MB; download) -- Guests: Open Lines with Dr. David Livingston. Topics: A short film - Angelfish, human factors for space travel, artificial gravity, space communications, science fiction movies & long term science projects, risk taking. 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. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. This is about a 2.5 hour Open Lines discussion. We started by talking to Michael Tyburski, an independent film maker who made a short film, Angelfish, and used The Space Show clips in the background. Michael described his film, why he put The Space Show in it, and more. Visit www.michaeltyburski.com for more information. Next, Dr. Jurist talked with us about artificial gravity & the chart he created to show just how big the radius would have to be to spin at 1G & other levels including lunar as well as Martian gravity. This chart is on The Space Show blog so you can follow along with what Dr. Jurist talked about regarding artificial gravity and spin rates. Our last caller for the first hour long segment was Jay who discussed the Space Literacy Foundation (www.spaceliteracy.org). Jay talked about the need for better space communications with the public as a way to facilitate more support for space. He also responded to questions I asked him about myths dealing with our early space program and the general population. If you are interested in what Jay is doing, contact him through his website. In our second longer segment, Ron called in to talk about the history of the wheels on the Lunar Rover and an ad campaign by Goodyear that incorrectly describes the history of the rover wheels. Ron talked about the use of piano wire, how the original wheels were made, who made them, and more. The paper about this important history that we mentioned on air can be read at www.hq.nasa.gov/alsj/lrv_historical_origins.pdf. We talked about the history of the lunar rovers, the cosmic radiation impact on them over time on the Moon, and their design which included harmonic drives and engineering to shield from lunar dust problems. He mentioned a good source of information, a journal edited by Eric Jones & Ken Glover, the Apollo Lunar Surface Journal. You can find this journal at www.hq.nasa.gov/alsj. Ron directed listeners to the document section for Apollo 15, 16, and 17. John from Atlanta followed Ron, had much to say about the recent success of the Dragon & Falcon 9, then he talked about human factors, one way Mars missions as being suicidal, the regulatory environment & the possibility of excessive or restrictive regulations. We also talked about the new sci-fi movie, Prometheus. The article I mentioned about the movie can be read at http://cavalorn.livejournal.com/584135.html. If you plan on seeing the movie, I suggest you see the movie first, then read the article which is titled Prometheus Unbound: What The Movie Was Actually About. It is written by Cavalorn. Tim was our final caller. He took issues with human factors medicine & Dr. Rowe. Also the risk of over regulation, especially if someone dies going to space. He expressed his thoughts on other things as well. While our discussion was civil, as you will hear, I did not agree with much of what he advocated. I urged him and other space enthusiasts to be more inclusive of other ideas for space exploration and development rather than just believing their way is the best or even the only way. If you have comments/questions, post them on the blog. If you want to email those that called us, send your note to me & I will forward it for you.

Dr. William (Bill) Rowe, Sunday, 6-10-12 (75.03MB; download) -- Guest: Dr. William (Bill) Rowe. Topics: Space medicine, magnesium, calcium & astronaut heart problems, oxidative stress & exercise protocols in space. 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. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed back Dr. Bill Rowe to further discuss certain aspects of human spaceflight (HSF) and space medicine. Please note that all Space Show programs are educational programs. This particular interview with Dr. Rowe is no exception. As an educational program, Dr. Rowe, at the end of the interview, offered to respond to your serious comments & questions posted on the blog and said you could email him through his website, www.femsinspace.com. Unlike most space medicine discussions, Dr. Rowe goes into lots of details on several key issues. I have no doubt that some of you will reject, challenge, and not like what you hear. Some of you will take issue with Dr. Rowe & be critical of this program. You might even see him as being negative though that is not the case, but he is definitely scientific. I urge you to discuss disagreements, challenges, & issues with him. Civility is the only requirement. During our first hour of this nearly 2.5 hour discussion, Dr. Rowe started out by going over astronaut cardiac issues, referring to former astronauts Jim Irwin & Dave Scott on Apollo 15 pertaining to issues with Irwin's hear rate. The articles he mentions on his website are in the upper left hand corner of the home page. Dr. Rowe then segmented into the first of many magnesium discussions & oxidative stress, using his submarine analog, (www.femsinspace.com/Oxidative_stress.htm. Microgravity exercise routines were discussed along with the need to get rid of excessive body heat. Dr. Rowe had much to say about the inadequacy of current on orbit exercise routines & heat. He also talked about plasma leakage, the loss of magnesium, & what this does in space. Also in this segment, he went over the Chinese Taikonaut requirements for female crew members, making the case for an all female crew. Don't miss what he had to say about this. Our last topic in this segment was 1G and artificial gravity. In our second longer segment, Dr. Rowe talked about recent studies pertaining to calcium usage & he brought this home to HSF. We talked about the importance of the calcium-magnesium ratio. Caller John introduced us to the issue of Vit. D3 & calcium. Tim called to make some good points about artificial gravity in terms of needed data points. He did not agree with the all female crew suggestion. Next, Dr. Rowe talked about the gastrointestinal lining, iron, & bone issues in space. Dr. Rowe also referred to anthropological studies to see how some groups habits might positively impact skeletal muscle issues in space. Issues with high adrenalin levels were discussed throughout the program along with possible treatment/intervention tools. At the end, we learned that resolving these complex issues is not just a matter of more money. I also asked Dr. Rowe about private Mars missions & one way trips with private crews ignoring space medicine factors. He called them dreamers but in the end if they want to go knowing the risks, they should be able to go. Dr. Rowe said his research & comments were focused on scientific HSF missions, not the dreamer type missions we often hear & read about in the media. Post your comments/questions on The Space Show blog. You can email Dr. Rowe through his website. Selected by: David Livingston [ stations ], Mon, 11 Jun 2012 16:23:34 UTC

Dr. Nader Elhefnawy, Friday, 6-8-12 (56.50MB; download) -- Guest: Dr. Nader Elhefnawy. Topics: Space warfare reality and hype. 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. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed Dr. Nader Elhefnawy back to the program to discuss his March 26, 2012 Space Review article, "Why we fall for the hype: contextualizing our thought on space warfare (www.thespacereview.com/article/2052/1)." This was about a two hour program with a break after the first hour. Dr. Elhefnawy also has two blogs which may interest you: http://naderelhefnawy.blogspot.com and http://raritania.blogspot.com. We started our discussion by talking about Dr. Elhefnawy's interest in the subject, his previous Space Review articles on the subject, and the issue of making accurate predictions. Nader suggested that there is much hype driving the technology predictions suggesting a possible space warfare outcome that also drive political policy in some instances. He talked about how technology development in the 19th century had more impact in changing the world than modern era technology. Our guest cited examples of this throughout our discussion but one example we talked about more so than others dealt with the development of the telegraph. Dr. Elhefnawy suggested that most of the hyped space weapons systems are not doable in the first place. Another document he cited about this issue was the Joint Vision 2020 report (www.fs.fed.us/fire/doctrine/genesis_and_evolution/source_materials/joint_vision_2020.pdf). Nader talked about space weapon systems vulnerabilities and again said that the expectations and hype do not match reality. Several callers engaged with Nader on cause and reaction, SDI, missile defense, anti-satellite warfare, and the pre-positioning of weapons platforms in space. In our second segment, I asked our guest how we in the public can best defend ourselves against hype, rhetoric, political agendas, and more given we do not have the expertise to always be able to pick up on the excessive claims and fears. As you will hear, we remain vulnerable to excessive hype not just on technology and space but on a wide range of things impacting our national and international policy. In this segment we did talk about technology being developed by China, inquiring if Nader thought this was all hype too. Nader cited some operational stats to drive home some of his points. Other issues and game changing technologies that came up in this segment included drones and the launch cost for space access. Nader also talked about the Eureka Paradigm and then he received a question from caller Mike about the European Code of Conduct that we have discussed many times on the show. Near the end, an interesting comparison was made with aerial warfare from 1914-1918. In just 7-11 years, aviation had advanced to fighting in the skies in WW1. More than fifty years after Sputnik, the point was made we are not even at the 1914 equivalent level for space warfare, thus supporting Dr. Elhefnawy's premise that we fall for the hype in this matter. Please post your questions/comments on The Space Show blog. If you want to email our guest, please do so through me and I will forward your note to him.
