AIAA Augustine Commission Panel Discussion Held On Monday, 10/5/09 (58.83MB; download) -- Guests: Bob Dickman, Elliot Pulham, Dr. Scott "Doc" Horowitz, Frank Culbertson, Jim Muncy, Dr. John Klineberg. Topics: This program provided a comprehensive discussion of the Augustine Commission options for our human spaceflight program. This special program was produced by AIAA with help from The Space Show. Our panel members were with us for two hours (no break) to engage in an in-depth discussion of the Augustine Commission's "Review of U.S. Human Space Flight Plans." Bob Dickman, Executive Director of AIAA started off with an opening statement on behalf of AIAA and then each of our five panel members made an initial opening statement pertaining to their perspective for the Augustine Commission report and issues facing our nation's human spaceflight program. After the panel member opening statements, as moderator, I led off with the first question that had to with making the case with the American public for human spaceflight with a compelling reason for the investment of public money for this program. After the panel addressed this issue for several minutes, I brought in questions from listeners across the country. During our two hour panel discussion, we covered the options put forth in the Augustine Commission Executive Summary, commercial space and what it is, COTS, heavy lift, on orbit construction, potential fuel depots, Mars and beyond missions, returning to the Moon, international support and consortiums for our civil program, leadership issues, congressional appropriations, ITAR, and more. Again, this was a very detailed and comprehensive discussion representing diverse views on how best to move forward with our human spaceflight program in the context of the Augustine Commission report. I strongly recommend this program as a MUST LISTEN TO SHOW! In addition, I want to thank AIAA, specifically Bob Dickman, Klaus Dannenberg, Duane Hyland, and Craig Day. I also want to thank both Janet Stevens of The Space Foundation, and Sharon Smith of Orbital who helped make this program possible. Without the help, labor, and support of all of these people and their organizations, this special AIAA/Space Show program would not have happened. Please note that Dr. Harrison Schmitt who was originally scheduled to be part of the panel had to cancel at the last minute. We were all most appreciative of Jim Muncy coming on board at the 11th hour to fill in for Dr. Schmitt. If you have questions or comments for our panel members, please address them to me at drspace@thespaceshow.com. I will send them to our contact for this panel at AIAA and we will do our best to get a response to you from the person you want to hear from.

Thomas Gangale, Monday, 10-5-09 (50.40MB; download) -- Guest: Thomas Gangale. Topics, property rights in space, lunar commerce, space law, treaties. Thomas Gangale was our guest for this show regarding his new book, "The Development of Outer Space: Sovereignty And Property Rights in International Space Law." This book will soon be available through the One Giant Leap Foundation website Amazon book partnership page. If you buy the book through the OGLF link, Amazon makes a contribution to The Space Show/One Giant Leap Foundation so we appreciate your purchasing Tom's book through this OGLF Amazon partnership. As soon as the specific OGLF URL is available, it will be added to this paragraph. In segment one, Tom told us that researching and writing this book represented a personal journey of exploration into international space law. As a result of his research, he came to change his mind about the Moon Treaty as Tom was a member of L5 and had actually worked to prevent acceptance of the Moon Treaty back in the day. Listen to him describe his journey and process. We also spoke about the need to lower the costs for space access to facilitate commerce. We talked about using commercial rockets for Earth to LEO, freeing NASA to do deeper exploration from LEO and beyond. The issue of the Moon Treaty language came up, common heritage of mankind as well as benefit sharing. Tom explained the significance of this language, some listeners challenged him but in the end its an important discussion so don't miss it. In his book, its addressed in far more detail. In the second segment, Tom discussed natural law, common law, and customary law along with property rights as understood in the Outer Space Treaty (OST). He also put forth the argument for an international legal framework to support commercial space development. We talked about mini treaties and alternatives to treaties given how hard it is in today's world to get treaties accepted and ratified. During this segment, Tom received a listener question about his days with SDI. Don't miss what he had to say about that experience. Toward the end of this segment, a question came in about bioprospecting on Mars. This produced a most interesting discussion, don't miss it. In the third and final segment, we talked some more about the common heritage of mankind issue, capitalism as the dominant paradigm, and what needs to be in place to support a stable framework for commercial space development. The Augustine Commission was discussed relative to property rights and space policy. Natural law was brought up as was John Locke and the Lockean view with regards to property rights. Toward the end of the program, I asked Tom if he had an Action Plan or time line for establishing the type of framework needed to support space commercialism. He said first that the government needed to blaze the frontier development and NASA needed to get out of Earth to LEO transportation. We must drive down the cost, we likely needed new propulsion and even structural air frames and more. Tom suggested we are treading water right now. Another thing he called for was for the cessation of bashing NASA and to always include a positive with the criticism. Prior to the end of the show, Tom took us through some 1950's space history and went through the facts showing us that the US did not rush to ratify the OST! If you have a question or comment for Thomas Gangale, you can email him at teg@ops-alaska.com. Selected by: David Livingston [ stations ], Tue, 06 Oct 2009 03:02:15 UTC

Rick Tumlinson, Sunday, 10-4-09 (56.25MB; download) -- Guest: Rick Tumlinson. Topics: Space frontier development, private/public partnerships, Augustine Commission. Rick Tumlinson returned for this special two hour Space Show program. Each segment was one hour but an overriding theme went through the entire show. This theme was the need to develop the space frontier and that the private sector could do it, that the government civil space program should address space exploration from LEO and beyond, but Earth to Leo should be turned over to the private sector companies. As Rick said, NASA should buy the ride, not the rocket. We started the show in segment one with a discussion of Rick's family background in co-founding the Texas Rangers and in fighting for freedom at the Alamo. We then extrapolated this thirst for freedom to the freedom needed to develop the space frontier. Rick talked about his early days of getting started in space advocacy, the Benevolent Conspiracy, and then we addressed the importance of X-Prize and the five year anniversary of SS1 winning with its flights over Mojave. Rick told us some stories from those early days, from the X-Prize challenge and more. Don't miss it. Another issue that came up during this segment dealt with the use of the term space tourist. Adventure traveler or some other term seemed a better fit for riding on a rocket and doing something as trail blazing as these early space adventurers. Listener Richard Godwin called in to talk about SpaceX and the Dragon capsule and NASA's future challenge, COTS and more. Toward the end of this listener call, the subject of fusion reactors aboard Navy ships came up as evidence of changing and improving technology. Marshall asked a question about lunar water and a possible X-Prize for processing a gallon of lunar water. Rick addressed the issue of prizes by saying they were important but that the winning of the prize had to be followed up by the existence of long term commercial demand. Toward the end of the first segment, the subject of range fees came up during our discussion of the Mid Atlantic Regional Spaceport in Virginia. As we started segment two, a question was asked rick about the Chinese space program and including China in the ISS partnership. Don't miss what Rick had to say about this. We then talked about the Augustine Commission and Rick said it was a fork in the road regarding the government space program. He was very critical of Ares 1 and the money spent plus spending additional money on anything to do with Ares 1 or that program. In the context of the Augustine report, Rick again talked about the need to open the frontier and how Augustine was pointing the direction toward that goal. He said the big losers were those supporting the NASA status quo. He also suggested that this would be a test of the new NASA Administrator. For his concluding comments, Rick reiterated the need to industrialize orbital infrastructure. Don't miss his concluding words.

Dr. Erik Seedhouse, Friday, 10-2-09 (59.57MB; download) -- Guest: Dr. Erik Seedhouse. Topics: risk aversion, lunar development, leadership, space with a vision, bio ethical issues. Dr. Erik Seedhouse was our guest today to discuss his book, "Lunar Outpost: The Challenges of Establishing a Human Settlement on the Moon." As we started the program, we asked Dr. Seedhouse about Air Force Captain Joe Kittinger's parachute jump from the edge of space given that Dr. Seedhouse was with the legendary 2nd Battalion, the Parachute Regiment, the world's most elite airborne regiment. Erik explained the major risks and problems in jumping when there is no atmosphere to push off of and use to control your jump. He discussed the problem of the flat spin and why it’s fatal, the differences with HALO jumpers, and the use of a drogue chute. He predicted that Captain Kittinger's record would be broken next year, so don't miss this discussion. After talking about skydiving from the edge of space, we turned our attention to lunar outposts and development. One thing Dr. Seedhouse mentioned that would be helpful was more international collaboration on the part of NASA, specifically he referenced the ESA Aurora Program as a possibility for collaboration. We talked about the Ares-1 rocket and the thrust oscillation problem and then turned our attention to safety and the NASA safety record. Here Dr. Seedhouse had some very interesting observations so don't miss this discussion. We started the second segment with a continuation of the safety subject and then the need for education about space, science, and engineering. We talked about some of the major issues to be resolved for having a lunar outpost including lunar radiation and lunar dust. He received a question about lunar lava tubes for an outpost. You will certainly want to hear what he had to say about the lava tubes. We talked about inspiration, heroes, raising the human spirit and what he said was the core value of NASA, exploration. Ticker tape parades were mentioned as one of the ways we used to honor and reward our risk-taking pioneer astronauts. The subject of water on the Moon came up and he thought it might be overblown in terms of being a driving force for settlement at this time. In needing one ton of regolith to extract about two pints of water, much has to be done to improve the extraction process or find more water for it to be useful for a settlement. We also talked about astronaut training in a commercial environment versus what NASA does. Don't miss this discussion. The Chinese space program was brought up via listener questions and Dr. Seedhouse had much to say about China, potential ISS participation, and a future space race with the U.S. Another listener brought up the Augustine Commission report and Dr. Seedhouse suggested we might be back to the Moon around 2023 rather than 2020. Toward the end of this segment, we spoke about different types of propulsion including the nuclear rocket and plasma propulsion, specifically VASIMR. In our human factors discussion, medical standards for commercial astronauts were compared to NASA astronauts and we talked about many of the important bio ethical issues. Erik also brought up the idea of pre-emptive surgery for long duration space flight. As we moved into the third segment, Erik spent more time with us on the bio ethical issues such as what to do with a dead body, life support for a terminally ill crew member, should there be a straight jacket on board, should crew members under go pre-emptive surgery for gall bladders and the appendix, should their be genetic screening, and more. He said issues like this for long duration spaceflight were only now starting to be discussed. In the fourth segment, we spent some additional time discussing both physical and mental issues. Dr. Seedhouse told us about some of other space books and the two new space books about to be on the market. The balance of this segment was spent talking about the analog model for long duration, v Selected by: David Livingston [ stations ], Sat, 03 Oct 2009 04:37:15 UTC

Brent Sherwood & Dr. Scott Howe, Tuesday, 9-29-09 (49.23MB; download) -- Guests: Brent Sherwood; Dr. A Scott Howe. Topics: Space architecture, space development, life support systems, human spaceflight missions. Brent Sherwood and Dr. A. Scott Howe were with us to discuss their new AIAA published book, "Out Of This World: The New Field Of Space Architecture." During the first segment, space architecture was defined. This is important so make sure you hear it as it is applicable to our discussion of the subject. We talked about some of the issues that differentiate space architecture from its terrestrial counterpart. Among the many issues are the lack of gravity and even freefall of an object depending on where in space the object is located. Pressure, vacuum, radiation, and temperature cycling are important factors to consider and plan for as well. Later in this segment, the lunar dust environment was brought to our attention. Listeners asked about comments suggesting we were ready to go to Mars now with humans and that there were no technological or engineering show stoppers. Don't miss the response offered up by Brent and Scott. Another listener asked about the differences that would exist in the ISS versus a Mars Station. You will want to hear this! Toward the end of this segment, the subject of artificial gravity came up and we were pointed to Chapters 12 and 13 of the book which factually address this subject. In the second segment, which was extended to the end of the program, we led off with listener questions and then our guests made the point with us that knowing and understanding space architecture facilitated working in other space fields. The question came up as to how can we afford to be in space and build and do the things we were talking about on the show and that are discussed in the book. While there are chapters in the book that address this concern, Brent suggested the better question would have been how do we take the next step forward in space development given certain conditions we have to deal with rather than how can we afford any of it. Don't miss what our guests had to say in responding to this question. Studying space architecture was addressed and we learned about the SICSA program at the University of Houston School of Architecture ( http://www.sicsa.uh.edu ). The subject of remote control demo bases for the Moon came up and we were told about the Integrated Systems Health Management program that does work to develop habitat demos. We then discussed Antarctica analog sites and the degree to which the human interface with robotic structures is progressing. Toward the end of the program, Brent and Scott talked about the target audiences for their book which include their peers, aerospace engineers and designers, students, and the general public. There are 30 chapters with 36 professional contributors. At the end of the program, we discussed closed loop systems for space, advanced life support and overall life support closure.

Robert Zimmerman, Monday, 9-28-09 (43.20MB; download) -- Guest: Robert Zimmerman. Topics: Lunar water, Augustine Commission, space policy, climate change and sunspots. Robert Zimmerman returned to The Space Show as our guest for this program. We started the first segment with questions for Robert regarding the recently announced lunar water, Indian Space Agency (ISRO) and MIP reports of lunar water, the IndiaDaily.com article and how all this might impact U.S. space policy in light of the Augustine Commission report. Bob discussed in detail the lunar water announcements, the Indian contribution, and let us know what he thought the impact of all of this might be in light of Augustine, our economic situation, and the Administration in developing our new space policy. Listen to his analysis and conclusions and see what you think. His bottom line was that the lunar water announcement will turn out to be irrelevant regarding Augustine and the Administration. At the end of this segment, he introduced us to the key concept of Augustine and what appears to be an unfolding Administration interest and that is more focus and possible support for developing commercial space. In the second segment, we led off with two questions from Jack, the first being about the Chinese possibly joining in on the ISS and if NASA and U.S. Policy would encourage that development. Bob said China was not interested in this and wants its own independent space program. You don't want to miss his comments on the Chinese becoming part of the ISS partnership. Jack's second question focused on climate computer models and if such models incorporated sunspot activity in their analysis. This started a lengthy discussion on climate change that went through the entire rest of the program. In discussing climate change, we also introduced the National Review article about the very important climate temperature data having been lost and what this means for policy and legislation, plus toward the end of the program Bob told us about skewed tree ring data. You do not want to miss Bob's climate comments as he is a prolific writer on the subject and knows the science and policy from all sides. During the second segment, we returned to space topics and Bob updated us on what was happening with LCROSS and what it hoped to discover and more. Bob also talked about the upcoming initial launch of Falcon 9 and more. Toward the end of this segment, I asked Bob about our progress in the five years since Space Ship One had won the X-Prize. He said that we were still in a holding pattern. As we started the third segment, we asked Bob about Ares-1 if the press on it was bad or if the rocket in his opinion was awful. He pointed out the problems in developing any new rocket and thought that Ares-1 issues were overblown by the media. We discussed the economics of Constellation and referenced the recent GAO report on Ares-1 and its costs. This report is available on the internet and I urge listeners to download and read it if you have not already done so. You can find this report at http://www.gao.gov/new.items/d09844.pdf . During this segment, Bob also talked about the need for competition with rockets and put forth many advantages resulting from increased competition. A listener asked him about NASA prizes and Bob said they were a good idea and effective. Toward the end of the program, he was asked about heavy lift and took the position that it probably was not necessary given on-orbit construction possibilities. We talked about a panel discussion for The Space Show regarding heavy lift and that is being considered. At the very end of the show, Bob spoke about the need for freedom and choice in space and across the board in relationship to government policy and control. If you have questions or comments for Bob Zimmerman, you can find his email address through his website, http://members.bellatlantic.net/~vze3cxxp/zimbib.htm or you can forward it to me at drspace@thespaceshow.com .

Conrad Spirit of Innovation Awards, Sunday, 9-27-09 (40.34MB; download) -- Guests: Josh Neubert, Aaron Rusheen, Daniel Asturias. Topics: Spirit of Innovation Awards Program, Conrad Foundation, how to get an outstanding high school education. Today's Space Show program featured The Conrad Foundation and their Spirit of Innovation Awards ( http://www.conradawards.org ) for this year. Two first place winners were our guests, Aaron Rusheen who created the Final Frontier Apparel Company and Daniel Asturias who created the MotGen System. Also with us was the Conrad Foundation Executive Director, Josh Neubert. In the first segment, Josh introduced us to the Conrad Foundation and the Spirit of Innovation Awards, then provided us with a brief introduction to our student guests. Listen to what Josh had to say about this fantastic awards program because it clearly works and after you hear the two students, you will know why I say that. One listener asked if the Conrad Foundation was working with NASA in these awards and as you will hear, they have signed a Space Act Agreement with NASA and the organizations do work together. We also learned that 170 student teams competed for the awards! By visiting the above website and clicking on the Competition button at the top, you can see the student projects discussed on the show and learn about the different categories for the awards. Later in this segment, Aaron Rusheen began telling us about his mechanical counter-pressure space suit and the company formed for this project, Final Frontier Apparel. Listen to what Aaron had to say about the suit, his team, and the competition, as well as the engineering and design aspects of the counter-pressure suit. In the second segment which lasted until the end of the show, listeners asked Aaron some questions about his space suit design as well as the electro-muscular stimulation built into the suit to help prevent muscle degeneration. Aaron suggested that the value in this type of stimulation would be in saving money by not having to take heavy exercise equipment to orbit, plus it would save hours of time for the astronauts as they would not need to work out as much. During this segment, we had a surprise listener phone call from Nancy Conrad along with Rusty Schweickart. Do not miss our conversation with Nancy and Rusty about education, awards, rewards, and much, much more! We began our discussion with Daniel Asturias in this segment regarding his first place win in the renewable energy category with his team's MotGen system, a motionless hydrothermal vent generator. Daniel does an excellent job in describing this device to us, how it would be placed about 2 km under the ocean and how it would work virtually maintenance free since it’s made of very few parts. Daniel received some technical questions, including one about the precipitation of dissolved minerals. I believe you will be as impressed by the answer and knowledge of this student as was everyone else which is why his team won first place in this award category. Our discussion with Rusty, Nancy, and our two students led to a discussion of what makes these students special and how they were received by their peers. I believe this is an important discussion and listening to the perspective officered on STEM education issues for high school students from both Daniel and Aaron. I recommend you listen to this discussion. Notice how both students from different states, one from a public high school and one from a private high school focused in on the parental and family environment for pushing and leading students. Toward the end of the show, Josh talked about the next iteration of the Spirit of Innovation Awards and pointed out two key approaching dates for student entries. If you are interested, or if you know students who might be interested, direct them to the Conrad Awards website. If you have questions or comments for Josh Neubert about the Conrad Foundation, you can contact him through the website at www.conradawards.org/index.php?option=com Selected by: David Livingston [ stations ], Mon, 28 Sep 2009 03:12:31 UTC

Lynn Baroff, Friday, 9-25-09 (59.07MB; download) -- Guest: Lynn Baroff. Topics: Space education in public school, human-robotic systems integration, Mars, space policy. Lynn Baroff was the guest for this Space Show program. We started Segment one with a discussion of the upcoming NASA Lunar Lander Challenge to be held this year at NASA Ames the weekend of October 17-18. The public is welcome. Mr. Baroff is the leading judge for the event and my having been to the event last year, I know that this year's program will be even better. Mr. Baroff said there were 21 contestants this year, he described the rules of the Challenge and we also talked about the simulated regolith material. Several questions came in about the recent NASA announcement of lunar water and if this development would impact or add to the importance of this year's contest. This led us to a discussion about the lunar water announcement, the Augustine Commission, the U.S. Congress, and our plans to return to the Moon. Do not miss this discussion. During this first segment, Mr. Baroff stressed the need for there to be an international effort in space development to reduce costs. We also started the discussion regarding the California Space Education and Workforce Institute and public education in California and elsewhere re STEM, social studies and related space educational issues. In Segment two, we discussed education, students, parents, and teachers. We talked about the problem of teaching to the test and the fact that there are no tests for the science and space topics so they are not as heavily taught in the schools as those subjects used in the test, basic reading and math. Lynn spoke about the need for educational standards enforcement. Listeners asked about apprenticeship programs and Andrew in Tucson even suggested a novel video/YouTube type of program to assist parents in helping their kids with math and science homework. Again, don't miss this discussion and the listener questions.
In Segment three, Mr. Baroff was asked about the new badge security system at JPL for the Mars Rovers. As we learned, this was a NASA and actually a government wide security change that many people do not like. We also talked about how the media portrays technical experts on TV and in the movies, as nerds, socially maladjusted, and anything but a popular outgoing man or woman. Lynn suggested that this is a negative influence on school kids and may play a part in many turning away from the STEM subjects. He suggested a more positive portrayal of the technical experts across all media to change what has become a negative in our culture. In this segment, we started talking about the human-robotic interface and that for long duration missions or settlement, we would need to be able to trust and place significantly more reliability in our robotics and computers than we do now. It was said that everyone wanted a Hal 2000 but without all the problems and negatives. In Segment 4, I brought up the Dr. Spudis editorial on using space as economic infrastructure and the fact that it does not need to be in our consciousness. Dr. Spudis equated space development to the railroads. If you want to read the Spudis essay, you can find it here: www.spaceref.com/news/viewnews.html?id=1349. During the last part of this final segment, we talked about some of the major human factors needed for a human to Mars mission and why we are not yet ready to undertake such a mission. This is definitely a discussion you will want to hear. If you have comments or questions for Lynn Baroff, visit his website at www.csewi.org. You can email your comments or questions to him at info@csewi.org. Make sure to reference both his name and The Space Show in the email subject line.

Larry Williams, Tuesday, 9-22-09 (42.76MB; download) -- Guest: Larry Williams. Topics: Next Step In Space, Commercial Space, SpaceX, Augustine Commission. Larry Williams, the VP for Strategic Relations for SpaceX, was our guest today to discuss the newly formed commercial space organization, Next Step In Space (www.nextstepinspace.com). During Segment One, Larry provided us with the background and genesis for founding Next Step In Space and we discussed the commercial space members of the organization and the difference in ISS access and transportation versus going to the Moon, Mars, and beyond. We also talked about the recent Dr. Griffin congressional testimony regarding the Augustine Commission hearings and Mike's public email in which he put forth his comments regarding the Augustine Commission. If you want to read his testimony and the email, here are the respective URLs: Congressional testimony: http://www.spaceref.com/news/viewsr.html?pid=32378; Dr. Griffin email: http://www.spaceref.com/news/viewsr.html?pid=32351. In this segment, we started the discussion regarding using EELVs for ISS cargo and crew transportation and Larry explained to us the initial intent of the VSE in which ISS access was treated separately from visiting the Moon and going to Mars. Somehow these respective missions have become blurred and confused over time and with lots of rhetoric. This subject continued through the other segments of the program. In Segment Two, we started off with a question from listener Jack regarding the probability of the Obama Administration investing more in R&D, specifically space R&D. Jack offered a quote from President Obama to suggest his administration would be investing more in R&D than previous administrations. You do not want to miss this discussion. In this segment, Larry told us about the new White Paper published by Next Step In Space and available to the public at www.nextstepinspace.com/downloads/NSIS-White-Paper-Sept22.pdf. In many ways, this White Paper was a response for accurate education regarding the VSE, Constellation, etc. to members of Congress regarding the Augustine testimony, plus the public. I recommend you read this paper. We also talked about COTS, NASA using Soyuz to access the ISS, and the business/financial consequence of that decision on earlier COTS participants. The issue of extra money for NASA came up and as Larry clarified for us, to do all of the NASA programs talked about in Augustine, an additional $5 billion per year more would be needed, not the much referred to $3 billion annual increase. Don't miss this important clarification. The subject of inspiring others, students, and the population came up during this segment. In Segment three, we focused our attention on Next Step In Space, learned how it was funded, how each of us can join and participate in it, and we talked the need for heavy lift rockets. Near the end of the program, Larry was asked to summarize his years with SpaceX and talk about how the perception and reception of the company has changed from its early days to the current time with successes and amazing projects under its belt and on the way to implementation. Larry had much to say in response to this question so don't miss it. Clearly, SpaceX has and is achieving great things for breaking the paradigm of how we access space and undertake commercial space projects. Hear now how the view of SpaceX from outside the space community has changed over time as these programs have come to fruition. If you have questions or comments for Larry Williams, please email him at larry@spacex.com.

Al Reisz, Monday, 9-21-09 (43.66MB; download) -- Guest: Al Reisz. Topics: space exploration, ECR space propulsion engine, space policy, Augustine, LCROSS. Al Reisz was the guest for today's Space Show program. The first segment started with a look back at some of Al's earlier work with the Saturn V and the J-2 engine. We spent some time discussing testing and the need to learn by failing in order to have success. Mr. Reisz had much to say that was important on this subject, don't miss it. We then discussed the work he is doing on his ECR, the Electron Cyclotron Resonance Space Engine. We discussed ion propulsion and how it works, the VASIMR engine, and the timeline for bringing ECR online. Mr. Reisz was asked to explain the advantages and why people should care about developing this new technology for space travel. Listen to what he had to say. In the second segment, Al was asked about the case for exploring space and he talked about the need to develop new science for the benefit of humanity. We then linked this need to new technology such as the ECR. Mars human missions were discussed in the context of what the ECR would mean for rapid to and from trips to Mars and we also brought up space policy in light of the Augustine Commission findings. Listeners had many questions for Al including questions about his thoughts on the Ares 1 rocket given his Saturn V experience. You do not want to miss what he had to say about Ares 1 and Constellation. Toward the end of this segment, Al was asked about fusion space energy and his thoughts on space solar power. He also talked about our need to promote space better. In the third segment, we talked some more about the Saturn V and the J-2 engine and how to better involve the public in developing and implementing space policy. I asked about some of the comments I read in a recent essay on space development by Dr. Spudis regarding the use of space for our economy and wealth building, but that like the railroads and trucks on the highway, space does not have to be in our consciousness any more than railroads are in our consciousness. Al agreed, but said that since we first needed commercial space infrastructure, we still had to promote and work to get space to the point where it could support industrialization as did the railroads once their development was in full motion.

The scheduled impact is Oct. 9 of this year. To learn more about the work and ECR of Al Reisz, visit his website at http://www.reiszeng.com .
