Dr. John Jurist, Dr. Haym Benaroya, Tuesday, 9-13-11 (67.04MB; download) -- Guests: Dr. John Jurist, Dr. Haym Benaroya. Topics: Creating the perfect U.S. Civil Space Policy, Part 1. 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 Drs. Jurist & Benaroya to help design the "perfect" U.S. Civil Space Policy. Part way through the program, we realized that we would need a Part 2 so our guests will return in a few weeks to propose our Action Plan. During Part 1, we thrashed over the problems, how to deal with them, and we took listener calls & emails with their important feedback. All in all, the three of us were very satisfied with how Part 1 unfolded. We still want your feedback so post your comments & ideas on the blog. In our first hour long segment of our two our discussion, our guests along with listeners went over some of the common problems faced in designing space policy. We had a focus on connecting with the general population and at times, listeners said we were doing the same thing we said others do such as say/propose the same thing over and over again expecting a different outcome. We talked about ways to break the "Ground Hog Day Loop Model. During our first segment, we talked about R&D and Dr. Jurist proposed an idea for an independent committee to oversee space and remove congress from its micromanagement, especially with technology. Listen to his proposal and let us know what you think of it. We also talked about the very long term nature of space projects, usually lasting 5-20 years or so, while Congress funds annually, not long term. Our guests suggested ways to address this problem. At one point I introduced the iPhone, consumer electronics comparison. See what our guests had to say about that one! We also talked about ways of expanding and building the economy, even in times of constrained budgets. This discussion included comparisons with space, infrastructure & entitlement program costs and benefits. As we started the second segment, Ben from New Jersey called us with the idea that the large goal should be space colonization. We had a terrific discussion with Ben and by the time I summarized his call, we had a clearer idea of how to structure the action plan. John called in from Atlanta suggesting the first step was to return to human spaceflight ASAP and preserve our HSF lead. Once this is done, the space policy follows. Each of our guests commented on John's idea and all of us had much to say about U.S. leadership and space leadership in particular. Kelly called, agreed with John Hunt and talked about commercial space customers other than NASA, plus R&D & more. We talked about investment capital and situations that encouraged private sector investment. In closing out Part 1, each guest summarized their takeaways from the discussion and agreed to be back to deliver the Action Plan (policy) we talked about throughout our discussion. Feedback is crucial, we want your comments, ideas, questions on The Space Show blog. Selected by: David Livingston [ stations ], Wed, 14 Sep 2011 16:41:28 UTC

Robert (Bob) Zimmernan, Monday, 9-12-11 (77.99MB; download) -- Guest: Robert (Bob) Zimmerman. Topics: Space science missions, NASA budget constraints, civil space policy issues, commercial space, space politics. 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 Bob Zimmerman back to this two hour program. We took a break at the end of one hour so there are two segments to our discussion. In addition, there was an audio glitch at the start of the second session so you will notice some rough editing cuts. All of the substance is there but I had to cut out segments that were dominated by background noise to the point that the discussion was unclear at best. Finally, while The Space Show works very hard to avoid partisan politics, with Bob as the guest, that is not always possible and that was the case with this interview. That said, Bob was largely going after incumbents of all parties in his policy and economic comments, saying people wanted a change from do nothing members of Congress to those that support the status quo. He did talk about the two special elections being held today in NY and in Nevada, saying that people are changing how they vote due to their unhappiness with things in the country. When I tried to pin him down about space being a major component of the unhappiness, as you will hear, even from the NY caller who got in just before we shut down the program, space is simply not a factor. Our first discussion topic was the James Webb Space Telescope (JWST) and its funding problems. Bob had much to say on this issue, the fights within NASA and he referenced the excellent Space Review article of this week by Jeff Foust which zeroed in on the issue: http://www.thespacereview.com/article/1926/1. We then talked about space workforce issues. Bob thought this was a false issue. Since he does not believe in gov. space programs nor does he want them, he thinks the space workers will go to work for the privates & be unleashed from NASA & gov. constraints so their creativity & productivity will be substantially greater. Throughout the program, Bob expresses his displeasure about gov. space programs, repeating that he did not want a gov. program, not even for basic research. We talked about the ISS and the Soyuz rocket failure. Bob had much to say about this and said the policy leading up to this was idiocy spread over many administrations & congressional sessions. Caller Tim asked why NASA was a failure (he assume it was) & if we would get back to the Moon soon. Bob responded to both questions, see what you think of his answers. Our first topic in the second segment was the bat situation with the white nose fungus. Bob is an expert on this issue & I always get a bat update from him. The news is not good & you will hear him say we are seeing natural selection at work and the species extinction process. Tony asked about funding SSP & a pilot energy plant at the Canton Atoll in the South Pacific and Trent called from Australia to talk about the recent Falcon 9 engine anomaly. Near the end of the program, I asked Bob what he thought space policy would be like if we actually elected a space enthusiast president. He said he did not want that because he does not want a government space program. As the program was nearing its end, we talked about specific & very successful science missions, Blue Origin, space tourism, & suborbital spaceflight. Bob brought up the special elections & how people wanted change. Post your comments/questions on the blog URL. You can contact Bob through his blog, http://behindtheblack.com.

Laurie Wiggins, Sunday, 9-11-11 (46.06MB; download) -- Guest: Laurie Wiggins. Topics: Systems Engineering for space projects and development. 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. For more information about our guest, visit her website at www.ljwenterprises.com. In addition, visit the International Council on Systems Engineering (INCOSE) website for more specific information on SE at www.incose.org. We welcomed Laurie Wiggins back to the show and learned about her new businesses including LJW Enterprise. Ms. Wiggins updated us on her space activities and then jumped right into to a discussion on the importance of systems engineering (SE) across many disciplines, including space projects. Among the early discussion points for SE, we learned that it meets customer needs, looks at the big picture, and has grown substantially in its uses and applications since it was first introduced in the classroom in 1950 at MIT. We also learned that SE is a separate engineering discipline as are the other engineering fields such as mechanical, structural, electrical, and aerospace. Ms. Wiggins was asked about its use in other national space programs and she told us that ESA had a strong SE program as does Russia and other nations as well. We started our second segment asking Ms. Wiggins if a small start up company building rockets or something similar could afford to use SE. Laurie's response was most interesting so don't miss it. Also, she referenced two examples directly related to space, one with the Arianne V back in 1996 and another citing NASA's Lewis Spacecraft failure. Do not miss this discussion. Later in the segment when talking about SE benefits, Ms. Wiggins pointed out that were there a software error, in the early stages using SE it could be fixed for $100 in our example. If the error was not discovered until the test stage, the cost could be $400 to fix it. If the error needs fixing in the operational stage, it could cost upwards of $10K for repair.. For hardware, the ratio is 30:1 and even many times higher if the hardware is in operations when an error is discovered. As we started our final segment, Laurie was asked about SE and the recent Blue Origins failure. While she could not shed any more light on the failure than what has been reported in the news, she did say that she knew SE was in use with the company. As for the future of SE, it is very bright. It is expanding into medical equipment devices and even showing up in student internships and high school classes. Toward the end of the program, I asked Laurie about SE as part of a Power Point rocket project. She suggested we ask penetrating questions to determine if there is substance behind the theoretical rocket or if its vaporware, indicating that one would need to go at least three levels deeper in analysis than what is on the slide to detect a real project. Some of the questions she suggested included asking if there were any wind tunnel tests available with complete data. Another was to ask if a systems requirement review (SRR) was available and if there were any preliminary design milestones identified to date. We also talked about the Space Launch System, the Booz Allen Hamilton cost estimate for the heavy lift launcher of $38 billion and using that money for CCDEV2 companies as a potentially more cost effective option. If you have comments or questions for Laurie Wiggins, post them on the blog URL above. You can also email Laurie through her website at www.ljwenterprises.com/Contact.html.

Open Lines, Tuesday, 9-6-11 (62.70MB; download) -- Guest: Open Lines with Dr. David Livingston. Topics: Wide ranging topics including the Soyuz, ISS, specific film reviews, AIAA & 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. Our two hour OL program was divided into 3 segments but the topics crossed segments so this summary will reflect discussion topics but not specific segment details. Our first caller was Daniel calling from a hospital in NYC. As a Columbia student, he was interested in the AIAA, Cessna, & Raytheon sponsored Student Design/Build/Fly competition. To learn more about this program, visit www.aiaadbf.org. Daniel next talked about the possibility of the need to vacate the ISS as a result of the Soyuz accident a short time ago. Daniel had much to say about this subject, as did most every caller on the OL program this evening. After Daniel, we continued talking about the ISS and rocket safety. As you will hear, we provided statistics for flying AF combat missions as compared to riding on a rocket. According to recent Space Show interviews, AF combat missions are 1/20,000 in terms of risk while the rocket ride is around 1/70 - 1/80 for an accident. We took calls from Kelly who was critical of my positive support for Space X. Kelly also provided stats for how long the ISS could remain relatively trouble free without a crew. John Hunt called from Atlanta to talk about the Orion and SLS. We also talked about Blue Origin and their recent launch failure, their NOTAM, and Blue Origin patents. There was a discussion per a recent article in Pajamas Media by Rand Simberg about Dragon being used in an emergency to get crew to the ISS. The callers thought that was unlikely and that should a dire emergency exist, NASA & Russia would be more likely to fly the Soyuz, hoping for the best, rather than the Dragon. Kelly also pointed out that autonomous docking was not planned for Dragon. A few callers talked about the new sci-fi movie Apollo 18 and the reviews were mixed. This brought up a discussion of other recent movies that I recommended, Cowboys & Aliens as well as Captain America. Tim called in from Huntsville re the ISS issue, possibly higher launch prices than predicted for the Falcon 9, & RLVs & doing something other than destroying the vehicle if it has a problem. He suggested launching from the ocean on a drilling platform or someplace where debris fields and other issues were not as critical as launching from a land spaceport. He also talked about the Chinese SSP program as well. Our last caller was Sean Casey to tell us about an upcoming event in Silicon Valley at the Stanford Business School on Tuesday, Sept. 20. I will be there, check it out at www.vlab.org/article.html?aid=423. The event is titled The New Space Race Is On! Companies are launching in 10, 9, 8, 7.... Post your comments & questions on the blog URL. Send emails for callers to me & I will forward them. Selected by: David Livingston [ stations ], Wed, 07 Sep 2011 15:31:38 UTC

Dr. Jeff Bell, Sunday, 9-4-11 (78.05MB; download) -- Guest: Dr. Jeff Bell. Topics: Space Shuttle retirement, safety, and mythology. U.S. space policy, NASA, U.S. Congress. 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. Jeff Bell back to the show for a two hour plus discussion regarding the retirement of the space shuttle. Dr. Bell started out discussing shuttle safety and frequently referenced a recent NASA study found at http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20110008208_2011007983.pdf. Several listeners have contacted me that this report is highly controversial & statistically flawed, but these people did not call or email in during yesterday's discussion. As always, trust but verify. Jeff's discussion on safety was wide ranging and covered all segments of the interview. He focused on various risk factors, SRBs, liquid SSMEs, & shuttle operations. As we started the second segment, Jeff was asked about the Space Launch System (SLS) re safety since it is to be derived in part from using shuttle components. Jeff had much to say about this, not particularly positive either. He then went into a lengthy discussion about SRBs , their safety, different technology, liquid rocket engines and Space X. He also talked about the Challenger accident and SRBs. His discussion then switched to cost plus contracting as compared to the Space Act Agreement (SAA). Later in the segment, he talked about X-37B and said that there was no real justification for a government manned space program. He repeated this statement a few times during the balance of the interview. He mentioned secrecy in the NewSpace sector and Tim called in from Huntsville to explore that with him. We talked about lunar tourism, the space elevator, and space solar power with the news of interest coming from China. Jeff returned to shuttle topics such as the fly back booster and Phase B shuttle plans. Jeff talked about the recent Blue Origin launch failure, the CCDEV companies & was unaware of the effort to bring CCDEV participants under a form of the FAR, thus doing away with the SAA. He continued talking about Space X and Dragon, more on space tourism including lunar tourism, and had much to say on the suborbital industry, including his thoughts that it would not compete for science missions with sounding rockets which he also suggested were not doing much anyway. Don't miss his comments on this. Regarding policy, he said over and over again during the interview that congress was making decisions on pork for their districts. He also expressed his concern as did I that human spaceflight was very much at risk given our policy confusion and economic situation. As the end of this program was upon us, we fielded a few more listener questions but I also brought up the uniqueness of Steve Jobs and that we needed more gifted people in space like him, Elon, & others. We also talked about the contributions of Silicon Valley and Jeff had much to say about the Valley & its contributions, mentality, etc.. Jeff is not great at responding to emails but if you want to send him a question, do so through me and I will forward it to him. Please do post your comments and questions on the blog URL above.

Matt Bille, Tuesday, 8-30-11 (44.13MB; download) -- Guest: Mat Bille. Topics: The SmallSat evolution, microsats, and cubesats now and in the future and the relevance to us all. 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. The Small Sat Conference PPT presentation and paper by Mr. Bille and his co-authors will be posted on The Space Show blog at the end of this write up. We welcomed Matt Bille back to the program to discuss his Small Sat presentation entitled "Distant Horizons: SmallSat Evolution in the Mid-To-Far Term. We started our first segment with Mr. Bille offering a general definition of a microsat at about 100 kilograms or less. We talked about new uses for microsats, exoplanet exploration, even the possibility of a wider and more commercially valuable personal satellite industry. Also in this segment, we talked about the interest in microsats at the student level, even down to the high school level. Our guest said microsats were now on everybody's radar when in the past, that was not so. We talked about the history of the microsat industry and what our guest and his co-authors suggested in their presentation as a rebirth of the industry with waves of interest. Mr. Bille took a listener question about microsat orbits saying most are used in LEO but beyond LEO uses are emerging. Much was said about launch availability and launching as a secondary payload. A question also came in regarding the use of composites in the satellite manufacturing process. Additionally, Matt pointed out how even the large satellite manufacturing companies were getting involved with microsats and offered us several examples of this to illustrate his point. At the end of this segment, we asked about international interest in microsats and how that has and is changing. In our second segment, we talked about what is causing so much interest and attention from organizations that earlier on were not paying attention to this industry. Our guest focused on DOD as an example of just such an agency given that microsats can offer Earth imaging of about 1.5 meters resolution. Dwayne called in to discuss Operationally Responsive (ORS) Space and microsats. He pointed out the increasing value of UAVs and possible competition to microsats, and that their is even an interest in a stealth UAV. Later in the segment, we talked about thermal control and structural issues plus microsat swarms. A listener expressed concern about small satellites being used as weapons by more and more people having low cost space access. We talked about using the satellites for debris mitigation and our guest suggested where microsats might be on into 2020 and 2030. In our final segment, we talked about the DARPA 100-Year Starship Symposium as Mr. Billie is part of the organizational committee panel. The website for this DARPA program for more information is www.100yss.org. Our guest had much to say about this program and our future which is what the DARPA study attempts to address. You definitely want to hear this discussion and if you can attend the event in Orlando from Sept. 30-Oct. 2, 2011. Post your comments and questions on the blog URL above.

Deep Space-Mars Life Support Panel, Monday, 8-29-11 (57.83MB; download) -- Guests; Dr. John Jurist, Brian Enke, Dr. Vadim Rygalov. Topics: This is a webinar discussion concerning the comprehensive human factors requirements for a manned deep space or Mars mission. 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. Note the webcam video will be uploaded the URLs added to this summary and the blog upon completion of editing. In addition, on the blog post, you will find a PPT by Dr. Rygalov & one submitted by Brian Enke so refer to them during the discussion. We welcomed Drs. Jurist & Rygalov and Brian Enke back to the show for this two hour panel discussion focusing on the life support needed for safely conducting a manned mission to deep space/Mars. In our fist segment, after panel member opening statements, we zeroed in on the issue of radiation. This topic consumed most of the first segment. We talked about the types of radiation astronauts will experience, the difference between LEO and beyond LEO radiation, methods for shielding today and in the future, lifetime doses for radiation workers (astronauts) & the general population, plus the possibility of a private group disregarding the regs & laws to do a Mars flight regardless of radiation crew issues. Our guests pointed out the essentials needed to understand the radiation issue in full, including the mass of the crew vehicle & the flight time to & from the destination. Each of our panel members had lots to say on radiation and the subsets of information we discussed in this segment .As we started the second hour, microgravity issues were our focus, starting with artificial gravity and a long arm centrifuge using a tether. Dr. Rygalov spent considerable time talking about what happened with the person who has been in space the longest of anyone, Cosmonaut and medical doctor, Dr. Valeri Polyakov. As a medical doctor who knew how to protect himself in space, his routine was unique, but to this day he still has problems from his 438 days on orbit. We talked about partial gravity, how to do artificial gravity, spin rates, but also what to do while on the surface of Mars as that will be 0.38 of Earth's 1 gravity with no centrifuge. We also addressed mental and psycho-social issues. Dr. Rygalov took us through the four phases of time & conditions leading to mental breakdown needing constant Earth intervention as a requirement. Dr. Rygalov was asked to compare this to the Chilean miners trapped underground last year. Don't miss what he had to say about this. Crew size was the next topic & our guests had much to say on this issue with behavioral & clique issues heavily influenced by crew size.. Martian & lunar dust issues came up briefly. Many critical aspects of manned mission to Mars were not discussed because of the lack of time. One example would be the stability of Life Support technologies & equipment remaining stable, including hardware, bio-regenerative life support materials, etc. Also, most consumable supplies are only usable up to about 6 months or 1/3 of a Martian trip.. Post comments on the blog above. If you want to contact either of our panel members, do so through me. Selected by: David Livingston [ stations ], Wed, 31 Aug 2011 00:26:22 UTC

Josh Hopkins, Sunday, 8-28-11 (63.48MB; download) -- Guest: Josh Hopkins. Topics: Mission planning, design for crew hardware for deep space missions. 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 Josh Hopkins back to The Space Show for this special webinar broadcast. Note: for video streaming we used Adobe Encoder Live & we believe it failed to record the video. At this time, we only have the traditional Space Show audio for archiving. If we recover the video recording, we will archive the video URL along with the audio URL for this program. This program with Josh Hopkins is very important. Josh took us from the theoretical regarding the primary human factors issues including radiation, bone loss, muscle atrophy, and mental/psycho-social issues, and told us how they were designing & building the Orion crew capsule referred to as the Multi-Purpose Crew Vehicle (MPCV) for deep space. In our first segment, Josh introduced us to mission planning, both for near term and longer term missions & the differences in the planning process. Here, he is referred us to www.lockheedmartin.com/data/assets/ssc/Orion/humanexplore/SteppingStonesBrochure-FINAL.pdf for their outline of Human Exploration Stepping Stones. Check out their main website for even more information: www.lockheedmartin.com/products/Orion/humanexploration.html. We talked about NEO mission planning for a 5-7 month mission using an Open Loop Environmental Systems. From here, he briefly outlined the radiation risks & the related mission planning: Trapped particles in the Van Allen Belts, Solar Flares, Cosmic Rays. He described how they use calculation paths to model radiation of each type in each part of the crew capsule & how they design to protect & shield the crew from the radiation risks. I asked Josh how they plan, design, & build in protections against the problems associated with microgravity. We learned about "trades" that need to be designed for as there are microgravity requirements that are contradictory with radiation requirements. Josh spoke to these contradictions. Also in this segment, much was said about closed loop environmental systems re a Mars mission. One way to avoid recycling, its mass, & costs would be to use lots of mass for a Mars mission. The crew would take more supplies & materials with them. He explained all the trades in doing these evaluations. I asked if this scenario negated smaller rockets/ propellant depots. This was a comprehensive discussion. In the second hour a caller focused on nuclear submarine analogs. This led to my asking about gender issues for planning & operation in the subs as compared to the capsule. We also talked about the mental issues in this segment, crew planning & development around these issues, plus the trades with microgravity and radiation. Another listener asked about Demron for shielding & antioxidants to combat radiation damage. Josh talked about issues re the size of space for crew repairs, health concerns, even spacesuit egress & repairs. We talked about Orion being built to operate in a depressurized state. Crew communications with each other as well as with Earth for longer missions were discussed. We discussed artificial gravity. Final topics included Orion time line to operations, Apollo crew volume compared to Orion's, capsule vs. lifting body, reentry speeds from Mars & risk factors with a fast return speed. Post your comments on the blog URL above. If you want to email Josh Hopkins, send it to me & I will forward it. Selected by: David Livingston [ stations ], Mon, 29 Aug 2011 15:50:17 UTC

Dr. Chiao began our discussion with an overview of the NSBRI User Panel which helps NSBRI focus on high-yield research areas leading to effective strategies to enhance mission success & improve crew health. Dr. Chiao identified User Panel members and the seven NSBRI research areas. We talked about NASA funding, U.S. universities & research institutions, and international cooperation. Dr. Chiao was asked about microgravity issues & progress in the field in the absence of a variable gravity research station on orbit. Our guest had some interesting research & facts on this issue to share with us so don't miss them. He was asked by another listener about medical researchers and research just for the sake of research instead of being geared to flying missions. We talked about distributive research, the Russians on the ISS, the Mars 500 Study, & his visit to the Chinese space center. A listener brought up one way missions to Mars & our guest had much to say on this topic. This is an important & comprehensive discussion so again, don't miss it. Also in this first segment, Dr. Chiao told us about his ISS mission and food rationing, plus we talked extensively about space radiation, followed by exercise programs with the Russians & the U.S. astronauts and how they differed from each other. Space tourism came up as did spaceflight participants. The first topic in our second segment included a question from Clark in Sand Diego regarding astronauts as radiation workers. We talked about lifetime radiation levels at length, Mars and lunar missions & ISS long duration missions, all in the context of radiation which Dr. Chiao listed as the top challenge/priority for long duration human spaceflight. The idea of using older people for manned deep space missions was presented as a way to mitigate radiation issues. We then talked about the issue of using older people & what that really meant. This discussion opened the way for our discussion of an ISS medical event & the treatment for such an event, including space surgery which is non-existent at this time, & a fast emergency return to Earth. The issue of comparing long term human spaceflight to early American and European explorations like Lewis and Clark and the Shackleton Expedition. Dr. Chiao clearly stated why human spaceflight cannot be easily compared to these early explorations. Listen & see what you think. I agree with Dr. Chiao & have said so on air many times. Dr. Chiao told us about the new NSBRI facilities at Rice, then we talked about using SRBs for human spaceflight. Leroy had much to say about SRBs and liquids. Don't miss this important discussion, it may surprise you. Space suits were also discussed & at the end of the program, we talked about the shuttle retirement, U.S. space leadership, & space policy. Leroy was also a strong advocate for China becoming an ISS partner. If you have comments or questions for Dr. Leroy Chiao, post them on the blog. If you want do email him, do so through me.
