Tom Olson & Robert Jacobson for SIS 8, Tuesday, 5-4-10 (49.56MB; download) -- Guests: Tom Olson, Robert Jacobson. Topics: Space Investment Summit #8, commercial space investments. Our guests joined us for this program to talk about the upcoming 8th Space Investment Summit Conference to be held on Wednesday, May 26, 2010 from 8:30AM-6:30PM at the InterContiental Chicago Hotel O'Hare Airport in Chicago. For more information, please visit http://spaceinvestmentsummit.com. In our first segment, Tom and Robert provided us with a short history for the Space Investment Summit program and how each program targets a special niche in the market, aspect of the industry, and market. Our guests went through the proposed agenda, told us who the speakers were, some of the panels, and we talked about the content. The point was made that those in attendance learn how to make an effective "pitch" for your proposal. Networking opportunities were brought up and as you will hear, are exciting and dynamic. We talked about space R&D programs and at the end of this first segment, we talked about R&D as was carried out with the old NACA organization. Tom talked about related fields that were part of the focus for SIS 8 including alternative energy, biotech, nanotechnology, etc. As we started the second segment, a listener asked about the status of commercial space investment today, particularly in NewSpace, and if we should expect an investment bubble in this targeted investment community. You will want to hear what our guests had to say in response to this question. Another listener asked about the line between NewSpace and commercial space within the administration policy and FY11 proposals. Our guests and I agreed that the lines are fuzzy at best. Don't miss this discussion. Listener Reda asked what types of businesses were being overlooked or not yet part of the SIS series of meetings. Our guests thought that SIS was fairly inclusive. Tim called in from Huntsville to talk about point to point suborbital transportation and he eventually brought up the ramjet skipping model for point to point. This is another discussion you will want to hear though the guests and I were not so kind to point to point emerging from the suborbital industry. Later in this segment, Robert talked about his experiences in the morning at JPL for a business roundtable meeting and I asked about the commercial, private, and NewSpace awareness level of those at the meeting. No surprises in the response Robert provided us, but then we do understand the tight focus and time constraints for the type of work being done by these engineers at JPL as well as other NASA centers. Robert had some important observations for us to consider so please listen carefully. Our guests talked about investment in the COTS program and also Earth imaging which is showing how useful it is with regards the BP Gulf of Mexico well in addition to the Icelandic volcano. Toward the end of the program, Robert and Tom talked about the logistics for SIS 8 at the hotel, the registration process, and the registration costs. Before the program ended, we talked about the NANORACK project and Cubesats being part of SIS 8. If you want to send a question or comment to Tom, Robert, or both, for Tom, please forward it to me at drspace@thespaceshow.com and I will forward it to him. Robert can be reached through any of these websites: www.desertskyholdings.com;

Dallas Bienhoff, Monday, 5-3-10 (42.39MB; download) -- Guest: Dallas Bienhoff. Topics On orbit fuel/propellant depots. Dallas Bienhoff was the guest for this Space Show program to discuss orbital fuel/propellant depots. In our first segment, Dallas started out by describing the concept behind the orbital propellant depot which he said was similar in concept to a gas station for cars except it was in orbit. Dallas suggested that by using depots we could increase payload capabilities between 2-3 times were we refueling in LEO today. He also summarized the history of depots which goes back to the early days of the space age. He further said that depots would be an important part of a space transportation system. Another way of expressing the capability was by saying we could go from 20 tons to the Moon without using depots to about 51 tons landed on the Moon if filled up using LEO depots. A listener asked about cryogenic fuel transfer and Mr. Bienhoff explained this challenge to listeners. I asked him what would happen if the depot had a leak in space. Don't miss his answer to this question. Near the end of this segment, we talked about various orbits that could be serviced by a depot. He suggested putting the depots in orbits that most launch vehicles can reach to expand market potential. We also talked about technology challenges and possible show stoppers so don't miss his response to this set of questions. As we started the second the segment, we talked about docking and how the refueling process would be handled. A listener asked if the depots would be made available to private space companies, assuming the depots were government projects. We talked about the potential for offsite refueling using small tugs. We talked about launch and destination timelines using a LEO depot. Another listener asked if we could be a space-fairing nation without the use of depots. Dallas said they are not essential but they do increase what we can put into space. He said that depots are enhancers, not enablers. Listeners asked Dallas about the priority of depots within the Administration's FY2011 budget. Mr. Bienhoff suggested that the depot was a priority program, a flagship program. I then asked him to describe the next steps in the development project assuming the FY 2011 budget is passed as is by Congress later this year. Near the end of this segment, Dallas addressed the boil off issue and the life expectancy of a depot. As we kicked off the third segment, Dallas said that a depot could be located at the ISS as well as on the surface of the Moon or Mars but suggested the fuel be produced on the Moon and Mars rather than brought up from Earth. He also talked about the choice locations for a depot so listen to his suggestions on this. We talked about launch economics with the EELVs and the potential afforded the industry with the Falcon 9. We then applied some of these launch economics to developing SSP and it was said that the use of depots definitely facilitated SSP development. In talking about depot development, Dallas equated policy with needing a customer and that was a critical path to depot development. Much of this segment was focused on the critical path of needing a customer and the potential market. In the end, the depot must make economic sense and be lower in cost than the alternatives. If you have comments or questions for Dallas Bienhoff on orbital fuel depots, please send them to me at drspace@thespaceshow.com and I will forward them to our guest. Please be patient in waiting for a response to your email. Selected by: David Livingston [ stations ], Tue, 04 May 2010 14:50:01 UTC

Dr. Neville Marzwell, Sunday, 5-2-10 (63.16MB; download) -- Guest: Dr. Neville Marzwell. Topics: STEM, Aerospace industry recruiting and expansion for the future. Dr. Neville Marzwell was our guest for this program to discuss the findings and conclusions of his visit to 20 of the greatest universities in this country on an aerospace industry fact finding and recruiting mission. In our first segment, Dr. Marzwell explained the recruiting mission and then started sharing some of his findings, analysis, and conclusions with us. What you will hear during this show will likely startle, shock, and possibly even anger you. Dr. Marzwell talked at length about student expectations and entitlements, salary demands, at times, even wedding ring and car demands by those students getting married. As you will hear, our guest went into the detail of student attitudes and expectations but also talked about what the professors do and don't do and why type of classroom experience produces better trained and equipped students. Listeners brought up several related issues such at GPAs in excess of 4.0, why only visit 20 Tier 1 schools and none of the second or third tier schools across the country. As you will hear, the industry focused on wanting the "best" so they limited their tour to the top aerospace schools. Toward the end of the first segment, Dr. Marzwell talked about the nationality mix of students and where they were from and attitude differences among the foreign students as compared the American students. As we started the second segment, we heard that in many ways, the American aerospace industry was in a panic over what has been happening in higher education. The industry is now very concerned about what the future will be and what their place in the future will be. You do not want to miss this discussion as it takes a look at what is happening here in the States and the global economy and as you will hear, the industry is asking the hard questions. Dr. Marzwell did a superb job of connecting the dots and demonstrating what uncertainty, risk and the lack of strategic policy planning does to business planning. both at the company level and the industry level. During this segment, we also talked about government programs to improve education and asked which if any of the programs were working. We also focused on possible solutions to the problems being discussed. Dr. Marzwell suggested we needed to first figure out where the country will be in ten years and what type of country. Will we even want an aerospace industry or will we be outsourcing it, even for the Dept. of Defense as we do now in every increasing quantities. He suggested that getting jobs back in America was an important solution step and he said many times that we had to bite the bullet to get the jobs back at any cost. We talked about the absence of national leadership and he said there were a few leaders but they were emerging from the business community. As we neared the end of the program, he talked about space solar power as being a near term positive and his new work on developing SSP for the future. As we closed the program, our guest again said jobs were the starting point for turning our educational and aerospace industry problems around. If you have comments or questions for Dr. Neville Marzwell, please send them to me at drspace@thespaceshow.com. I will forward them to Dr. Marzwell but be patient in waiting for and expecting a reply as he gets hundreds of emails. Selected by: David Livingston [ stations ], Mon, 03 May 2010 15:49:47 UTC

Alan Ladwig, Friday, 4-30-10 (56.16MB; download) -- Guest: Alan Ladwig: Topics: Obama space policy, U.S. space policy, NASA outreach, NASA TV, NASA and politics. Alan Ladwig, Deputy Associate Administrator for NASA Public Outreach was our guest today. During this program, Mr. Ladwig referenced several useful and informative websites that I recommend for bookmarking. All of them start with a visit to www.nasa.gov. One site in particular that I suggest you visit often is their new video page, www.nasa.gov/multimedia/videogallery/index.html. In our first segment, Mr. Ladwig summarized the new approach to space policy recommended by the Administration in its FY 2011 budget proposal. To provide more detail on the policy, we learned about the study teams being formed to review and study many aspects of space policy and how to implement them in the new direction NASA is heading. Briefings to congress to provide them with more detail are in process. Alan spoke at length about the technology development program and listed numerous space technologies that will benefit from the new program. We also talked about the risk of the new policy and I asked him about IP ownership rights. During this segment, we talked about having a destination as a goal and Alan said we needed flexible destinations, not one fixed destination. To make his point, he referenced the robotic and science mission program which is very successful and does have multiple destinations as goals. He also told us that that having a single destination as has been the case for the past 40 years has proven unsuccessful. He fielded questions about extending shuttle and the GAP and said to do so takes money away from other programs. He also talked about having extended ISS to at least 2020. In our second segment, we led with a call from Stephen of the Direct 3.0 team who asked a series of three excellent questions that you will want to hear. After responding to Stephen's questions, Alan provided us with registration information for the coming Industry Day which will be May 25-26 in Galveston, Texas. Based on a question about stimulus money going for community organizing, the listener asked why NASA could not be properly funded. This resulted in a discussion about the politics of space versus competing government projects and interests, and the problems space has in connecting with the general public. Here Alan talked about extensive outreach programs. This is an important discussion and everyone is searching for answers. Later we took a call from Rick regarding heavy lift and the Direct launcher. We started our third segment talking about the recent Everett Group’s “Space Poll” from March 27-April 12, 2010 (http://www.spacepoll.com/sumreport041610.pdf). One thing our guest said was that NASA needs to do a better job of relating NASA work to STEM, the health industry, national security among others. This discussion went forward for the majority of this segment. Bruce called in to discuss nuclear rockets and power in space. Alan summarized the administration position on this so listen carefully. Toward the end of this segment, Alan talked about public outreach, including a Buzz Lightyear. Program. You won't want to miss his comments. In our fourth and final segment, we focused on NASA TV. Our guest told us it was a mission support technology and its communication venue was an added benefit. NASA TV has four channels which Alan described for us. He also provided us with some background on the restraints and operating parameters for NASA TV. He then told us about the new NASA Video website so see the URL for this site above. Toward the end of the program, I asked him to describe the budget process which he did. This was a most informative and important procedural discussion. If you have questions or comments for Alan Ladwig, you can reach him at alan.ladwig@nasa.gov. Your suggestions on how better to engage the public in space and with NASA are most welcome.

Dr. Robert Zubrin, Tuesday, 4-27-10 (54.19MB; download) -- Guest: Dr. Robert Zubrin. Topics: Human spaceflight, US space policy, Mars. Dr. Robert Zubrin was our guest for this non-stop two hour program to discuss the proposed changes in US space policy and why having a destination is so important for our national space program. For more information, visit The Mars Society website at www.marssociety.org. Note the coming Mars Society Conference which Dr. Zubrin told us about, scheduled for Dayton, Ohio from August 5-8, 2010. Dr. Zubrin started our discussion saying that we could go to Mars in about ten years as technology was not the issue. I then asked why even have a human spaceflight program and why Mars. Bob provided us with a comprehensive response and discussion to both of these questions. In fact, this nearly two hour discussion was action packed, covered lots of aspects of space policy, was very comprehensive, and while he was critical of administration policy, he also offered solutions to the problems he described. During our discussion, Dr. Zubrin had much to say about the Augustine Commission findings, Science Advisor John Holdren, the budget expenses earmarked for the ISS when the US will not be visiting the ISS except using the Soyuz, and more. Listeners asked him about nuclear rockets, specifically Vasimr. Dr. Zubrin who has his doctorate in nuclear engineering, had much to say about nuclear rocket propulsion including Vasimr and nuclear thermal which is quite different. Listen to what he had to say about these different types of propulsion and why one is doable and one is extremely hard and costly since it requires so much added power, the latter being VASIMIR. Dr. Zubrin dissected the administration plan, especially the part about heavy lift. Listeners suggested that the research called for in the administration plan for heavy lift was about getting affordable heavy lift. Listen carefully to what Dr. Zubrin had to say about this and the entire research program suggested in the administration plan. Bob went to great lengths to talk about why policy needs a destination and time line, be it the Moon, a NEO, or Mars. He offered us many insights about programs without destination goals and timelines. Do you agree with him? Other listeners asked him many questions about Mars Direct including a potential test flight program, tethers, artificial gravity, and needed milestones. He was asked about a Mars fly by mission or landing on Phobos, he talked about orbital propellant depots, the differences in radiation for an ISS crew as compared to a Mars Direct crew. Toward the end of the program, Bob explained the old but important political doctrine of Thomas Malthus known as Malthusianism and why this is the opposite of what space development is all about. Listen to what Dr. Zubrin had to say about this and its influence in the current administration. At the end of the program, I asked him for his thoughts on the use of commercial launch providers and he said he was supportive of that as long as they can meet the requirements and do it. He indirectly referenced the GAP in this discussion but again said a program without destinations and time frames is a flawed or no program at all. If you want to send a comment or question to Dr. Robert Zubrin, please do so through me at drspace@thespaceshow.com. Selected by: David Livingston [ stations ], Wed, 28 Apr 2010 16:19:28 UTC

Dr. William (Bill) Rowe, Monday, 4-26-10 (57.36MB; download) -- Guest: Dr. Bill Rowe. Topics: Long duration spaceflight human factors, gene modification. Dr. Bill Rowe returned for this Space Show program to discuss the concept of gene modification to permit humans to successfully engage in long duration spaceflight. Visit Dr. Rowe's website, www.femsinspace.com. In addition, two of the research papers Dr. Rowe mentions on the show can be found at these addresses:
http://eurheartjsupp.oxfordjournals.org/content/4/suppl_A/A8.full.pdf and http://content.karger.com/ProdukteDB/produkte.asp?Aktion=ShowFulltext&ArtikelNr=252852&Ausgabe=253992&ProduktNr=224091. In our first segment, Dr. Rowe put forth his thesis regarding long duration human spaceflight and some of the problems resulting from it that work against humans successfully engaging in this activity short of adapting to the environment. During this segment, Dr. Rowe outlines the issues and the problems and then sets the stage for the discussion potential solutions, specifically gene modification. This first segment is the foundation for this discussion. As we started the second segment, Bill summarized the magnesium deficiency and what it means and then identified four genes that might be the targets for modification. These four genes are ANP and N.O. regarding two vessel dilators and clot busters, Vessel Growth Factor (V.E.G.F), and Erythropoietin which builds up the blood supply. During this discussion, Dr. Rowe provides a detailed explanation of these genes and what they do and the reason why he believes these should be targeted for modification in human spaceflight. Dr. Rowe was asked questions about animal genetic research and its application to human genetic research, radiation, and ethical issues around human genetic research. He mentioned viruses being the most common vectors for genetic research but said the research was very much in its infancy. In the third segment, Dr. Rowe continued discussing the pharmaceutical problems when used in space and he was then asked about publications in the journals on these subjects. Our guest described the publication process as a political issue with lots of fear surrounding the publication of articles on this and related subjects. Later in the segment, the issue of cardiac atrophy came up in a question and G-force acceleration for people beyond age 30. You do not want to miss this discussion. Visit Dr. Rowe's website and if you have questions or comments for him, please send them to RoweRun@aol.com.

Dr. Jeff Bell, Sunday, 4-25-10 (62.36MB; download) -- Guest: Dr. Jeff Bell. Topics: space policy, space advocacy, human spaceflight. Dr. Jeff Bell returned to discuss space policy in light of the administration proposals. As you will hear in the this two hour interview, Dr. Bell had much to say that will irritate people on all sides of the issues and the space advocacy movement. So get comfortable listening to this program, listen carefully, and give thought to what Dr. Bell talks about. In our first segment, Dr. Bell referred to the Obama plan as Plan 1 and Plan 2. He even talked about the possibility of some of the issues in proposed policy changes finding their way to the courts for resolution. We then talked about Plan Bush and Jeff started speaking about the Orion part of Constellation. He referenced the Augustine Commission and said there simply was no funding levels for human spaceflight beyond LEO. He also said the five year time table in the Obama plan was too short and that we should probably defer human spaceflight for ten to twenty years to perfect new technologies that would get us to space at a significantly reduced cost. Dr. Bell took several listener questions about the impact of the US deferring human spaceflight for a decade or two. Listen to what he had to say about this action. When asked about the effort to go commercial, he suggested it was just paying different parties to do essentially the same thing. Toward the end of the first segment, the nuclear rocket came up for discussion. Jeff said it was not affordable and put forth a discussion detailing why the nuclear rocket was so costly. He addressed another listener question about policy taking too long, thus space policy has to be completed within a presidential term or the next president will change the policy again. Jeff disagreed with this listener and cited some examples of projects spanning different presidential administrations. At the end of this segment, he suggested there was no case to be made for going to Mars. As we started the second segment, he talked about robotic asteroid missions for planetary defense, not human missions. We talked about the Friday Washington Post editorial calling for the end of human spaceflight. In response to callers, Dr. Bell reiterated the need to stop human spaceflight until such time as new technologies exist to do it cheaper. During this segment, Jeff turned his attention to the space advocacy movement which he said had become more extreme and hostile as space policy becomes more questionable. He said there was no case for SSP and beamed power, going into this in some detail. We asked Dr. Bell about the X37B Air Force launch and then Dr. Bell talked about the need to move away from SRB boosters. He said the good thing in the Obama plan was the need to develop the kerosene engine which he thought might be possible within a five year time frame. As the show ended, he talked about space advocates having to learn to stop acting like 1960's sci fi programmed clones. Listen to his comments throughout the interview on this topic. He even urged space cadets to become deprogrammed by stopping to accept everything one reads and is told in the space news, on the space blogs, by organizations, etc. If you have comments or questions for Dr. Jeff Bell, please send them to me and I will forward them to Jeff. Be patient, Dr. Bell does not respond to all notes nor does he do so on a timely basis. Selected by: David Livingston [ stations ], Mon, 26 Apr 2010 03:53:29 UTC

Dr. Clay Moltz, Friday, 4-23-10 (59.15MB; download) -- Guest: Dr. Clay Moltz. Topics: Space Governance, Lunar Governance, space policy. We welcomed to the show Dr. Clay Moltz from the Dept. of National Security Affairs at the Naval Postgraduate School. If you are interested in downloading and reading the paper we discussed during the show, you will find it at www.au.af.mil/au/ssq/2009/fall/moltz.pdf. In our first segment, we led with the successful launch of the top secret Air Force X37 and the possibility that it might be a space weapons system. We also talked about why articles on this issue were coming out of Australia as well as other places. I believe you will find this to be a very interesting discussion. We then talked about lunar governance and our guest said we were not well prepared regardless of who goes first to the Moon and regardless of it being a commercial company or a government project. In this discussion, Dr. Moltz talked about the Antarctica treaty, the Outer Space Treaty (OST) and the Moon Treaty. The Law of the Sea Treaty was also referenced. As we started our second segment, I asked if each space destination would require a different set of governance standards. For example, how different would Mars governance be from lunar governance? We talked about the track record of US behavior in space and then took a look at the space behavior of other space fairing nations. The issue of space debris came up and Dr. Moltz told us about the 1960's Project West Ford. The subjects of nuclear power and nuclear rockets came up and our guest had some very interesting things to say about nuclear and space. This discussion then took us to the bigger question of space security. Dr. Moltz talked about DOD space guidelines, and the proposed space treaty by China and Russia which the US has not been supportive of to date. He explained some of the problems with it and then talked some more about the Law of the Sea Treaty which he believes we should have signed. In the third segment, we again focused on orbital debris. As a result of Marshal's question, Dr. Moltz defined space debris. If the item can be maneuvered, it would not be considered space debris. He also talked about the Chinese ASAT test and potential Chinese debris liability. We spent a major part of this segment talking about polluting the space environment and the efforts underway to avoid doing this. In the fourth and final segment, we addressed the US space vision. We asked Dr. Moltz if the VSE was dead and our guest summarized recent US space vision history. We talked about the Chinese vision and the role of the military with China. Toward the end of the program, our guest outlined probable components of the developing new US space vision which he believes will include a focus on commercial space, entrepreneurial development, international cooperation and partnership, and the modernization of ITAR. Before the program ended, I asked Dr. Moltz about nuclear proliferation and its potential impact on space development and if political sanctions against another nation actually work. You will want to hear what he had to say in response to both of these questions. If you have a question or comment for Dr. Clay Moltz, please forward it to me at drspace@thespaceshow.com and I will send it to Dr. Moltz.

Gwynne Shotwell, Thursday, 4-22-10 (32.88MB; download) -- Guest: Gwynne Shotwell. Topics: Commercial crew, Falcon 9, human spaceflight, commercial launchers, SpaceX. Gwynne Shotwell, President of SpaceX, was our guest for this special full hour program in which we discussed SpaceX, Falcon 9, Falcon 1e, commercial launchers, space policy, safety and so much more. To learn more about SpaceX, please visit www.spacex.com. Ms. Shotwell started our discussion with a SpaceX overview. We initially focused on the Flight Termination System and how the Air Force decides to use the system if the rocket flight needs to be aborted. Gwynne said the Falcon 9 launch window was around May 8-9 but it might be later depending on several factors. We also asked about the initial Falcon 1e flight so note the schedules, launch sites, and plans. We then approached the subject of safety for crew riding the Falcon 9 or for that matter any commercial rocket. Ms. Shotwell had much to say on safety issues, she clarified many misconceptions about this issue, and explained what SpaceX and others were already doing and must do to comply with space regs. This is a detailed discussion so don't miss it. We also talked about the COTS program, Bigelow space stations, using other rockets for Dragon, and orbital space tourism. A listener asked about the safety requirements for NASA astronauts being the same for orbital space tourism. As you will hear, they are two different markets serving different customer needs. Another listener asked about reusability and refurbishing which Ms. Shotwell spoke about in some detail. Additionally, Gwynne made it clear that SpaceX is selling a service, not hardware. You will want to be sure to understand this distinction. Yet another question asked about SpaceX designing an SSTO. What was interesting here was the fact made very clear by Gwynne that for a commercial company and project, engaging in long term R&D is not usually something that is done as the focus has to be on the product/service to generate profits. Gwynne was asked about new engine development, launching Dragon on other US as well as foreign launchers. At the end of the interview, I asked about SpaceX hiring of new college grads and internship programs. She gave us a resounding YES to both and suggested that those interested send their resumes to dolly.singh@spacex.com and visit their career page at http://www.spacex.com/careers.php. Applicants need to be US Citizens or legal residents. Before signing off, Robert in Los Angeles asked her if SpaceX would be doing an IPO or remaining private. Don't miss her reply to this final question. If you have a comment or question for Gwynne Shotwell, please be concise and send it to gwynne@space.com.

Open Lines, Tuesday, 4-20-10 (64.00MB; download) -- Guest: Open Lines with Dr. David Livingston. Topics: policy, Obama Space, commercial space, various space start-ups. This was a two hour plus OPEN LINES program with almost non stop listener telephone calls in addition to email and chat. We started our fist segment with a phone call from Bob Zimmerman. Bob did a 15 minute or so rant on Obama space, the April 15 space conference at the Cape and more so don't miss this energetic start for this program. At the end of Bob's comments, he spoke about some of the new Climategate issues that have come up and that he was going to discuss on national radio later in the evening. Mark Bray then called in and had much to say about our space policy, ISS, shuttle extension, and more. We fielded emails from Joe in Houston about parallels with canceling the Apollo program and today. Many listeners commented on Joe's question. Joe also introduced us to Vasimr as a discussion topic and it was brought up several times during this program, both as to being on the ISS and in deep space. As we started the second segment, Paul Graham of the open source Open Luna project called in. You can find out more about his project at www.openluna.org but he answered several questions and provided us with much information. If you are interested in more information about his open source project, contact him through their website or paul-spaceshow@openluna.org. Since he was calling in from Canada, I asked him for a Canadian perspective on the administration's space policy budget and suggested direction for NASA. You will want to hear his comments on this. John in Atlanta called in, spoke about shuttle, Orion, Vasimr and more. Amnon called in regarding Astronauts For Hire and suborbital space development. Dave Ketchledge called in to talk nuclear with us and human factors and engineering. We also fielded many other emails about the ISS, commercial space, space policy, and various companies such as SpaceX. At the end of the program, Terry phoned in to strongly urge the acceptance of the path that both NASA and Lockheed are presenting, he talked about his confidence in SpaceX which I shared and the fact that we are at an important crossroads regarding space. Listen to his suggested approach and see if you concur. Charles Pooley was our final caller just before I shut the program down for the evening and he talked about the new paradigm he promotes and Microlaunchers (www.microlaunchers.com). If you have a question or comment for any of the listeners that participated in tonight's show, send it to me at drspace@thespaceshow.com and I will forward it to the person of your choice.
