We welcomed Jay Wittner and Gary Bickford to the program to update us on changes and new developments with The Integrated Space Place (see www.thespaceplan.com). During the first segment of our 93 minute program, Jay introduced us to The Space Plan and explained the layout of the plan, how to enlarge it on our computers, then explained why it was a view of a detailed future for space development. Jay mentioned that the center column was the critical path of movement for the industry toward our space future in the year 2100. He talked about the continuing online work with the plan which Gary was doing and the fact that one could click on any part of the plan for specific information related to that mode.
Additional topics discussed in the first segment included their wanting to incorporate different perspectives from different players in the industry such as SpaceX, the need to present factual information and to over time present an evolving path to full space development. Paul sent in a question about the upcoming ISDC conference. Our guests had much to say about their two hour presentation at ISDC but we talked about this event in more depth during the second segment. Jeff asked if the plan was more focused on human spaceflight or science missions and another guest wanted to know if the plan was U.S. centric. In the second segment, our guests talked about the constant need to update and modify The Space Plan given the growth and changes in the space industry. Our guests cited several examples of ways in which the plan could be used. They used the example of how to get to the moon. Listen to what they had to say about this and the application to the question of The Space Plan. 3 D printing served as another example.
A listener asked our guests for the qualification for volunteers to help with Space Plan updates and changes. Our guests listed several areas of interest for potential volunteers. If you are interested, you can email them for more information at info@thespaceplan.com. Harry from Boston wanted to know if the group had any contact with NASA, DARPA and other government agencies involved in space. BJohn sent in a note asking if the first human mission to the Mars could take advantage of shorter travel time during the close conjunctions 2033 and -35 which was earlier than suggested by the Plan. BJohn also suggested the use of a 12 year cycle of launch windows for gravity assist from Jupiter to time missions beyond Jupiter. Don't miss what our guests said in response to BJohn's question. In addition, I got in a comment or two abut budgets and advanced propulsion. As the program was nearing the end, our guests focused on the center part of the Plan or what they refer to as the critical path. They also talked about policy and economics which will play a bigger part as they expand their website. Please read the rest of the summary @ www.thespaceshow.com.

We welcomed back Richard Easton with his guest, Dr. Bleddyn Bowen from the UK. Richard was the co-host for this program as he chose this as an Indiegogo perk during our recent website modernization campaign. Richard selected Dr. Bowen as the guest and was with us from Wales. During the first segment of our 94 minute discussion, Richard explained why he chose this particular topic and introduced us to Dr. Bowen. Dr. Bowen explained his space power theory as well who Carl Von Clausewitz was and what he was known for since his work influenced our guest and his academic work on developing his space power theory. Don't miss this early part of our discussion as it provided the foundation for the rest of our very thorough discussion on space warfare, security issues, strategies, and the use of space power.Some other topics discussed in the first segment included responsive space strategy, severe consequences for offensive behavior and actions, Cold War analogies, cyber warfare, space war games, beyond geosynchronous orbit, other space locations of strategic interest such as L4 or L5, and the HGEO orbit. In the second segment, Bleddyn was asked about space based weapons. Mike Listner called in with his thoughts on space weapons and space power per the discussion in the first segment. Bleddyn made the comment that his theory was not for the battlefield but more of a tool for studying the issue. BJohn asked many questions during our program. He wanted to know if the space solar power beam could be weaponized and on another he wanted to know if N. Korea could set off an EMP bomb. He also expressed his concern about the use of nuclear rockets and propulsion in space. Don't miss what our guest said in response to these questions. As our segment was winding down, I asked Bleddyn for a prediction of things ten years out. He suggested I was asking the wrong question, then he asked my question in a different way. Listen to what he said and how he responded to it. What do you think?Another listener question came in from Don asking about the influence on space power by a U.S. President, especially once our 2016 election is all over and done. Our guest had much to say on this subject, don't miss it. Chemical weapons, arms control agreements and conventions, WW2 and more came up leading us into a summary statement by both co-host Richard and our guest, Dr. Bowen. In their respective summary statements, Dr. Bowen spoke to the differences in space power and space security and the need for more awareness and what is known as space normal. Richard mentioned GPS vulnerabilities and new software upgrades to the system with more needing to be done to add to the security of the system. Please post your comments/questions in the comments section for this show when it is archived. You can reach either guest through me.

We welcomed back Henry Vanderbilt to update us on this year's Space Access Society Conference to be held in Phoenix, Arizona from April 7-9. Find out more about the conference, speakers, registration and more at http://space-access.org/updates/sa16info.html. During the first segment of our 92 minute discussion, Henry provided us with a short but detailed history of the Space Access Society conferences, then suggested the theme for this year will be looking at what will likely unfold over the thirty years along with what should unfold over the same future time period. One thing that he stressed for the future was expanding BLEO to cislunar development, specifically cislunar transportation. He said he was not opposed to going to Mars but he thought it best to be incremental in moving forward and first create the conditions and infrastructure to Make Mars possible in the future. For the balance of this segment, Henry highlighted many of the speakers and their topics. I suggest you follow along with the agenda which you can see at the above Space Access event website. Near the end of the first segment, Marshall called to talk about the commercial crew program and buying RD 180 engines. At one point Henry compared the cost of the RD 180 to the cost of buying a seat on the Soyuz to send American astronauts to the ISS. He said today's price was around $70 million per seat but when Dennis Tito did it years ago, the cost was about $20 million. In the second segment, Henry went over the variety of panel discussions planned for the event. He said a panel discussion is brain storming about the future. Refer to the agenda for the specifics on the panel discussions Henry mentioned. A listener asked about the event being live streamed. It is not but I brought up the bloggers that would be there so that those not attending can follow what is happening. If you are interested in following the bloggers, listen for the details in this segment. Henry also went through conference location and hotel information. While the main hotel is sold out, he said there might be some cancellations in a few days regarding people who had to make last minute changes in their plans. He also said alternative hotels are listed on the Space Access website. Nearing the end of the program, we talked about the exhibit area for the event which still has space available. If this interests you, email Henry through the Space Access website. Don in Las Vegas asked if there would be a memorial for Charles Pooley. Don't miss this short segment. I suggested having the Happy Hour in memory of Charles. Maybe that will happen. For the balance of our discussion, Henry mentioned other speakers, student projects, and a few additional concepts that would be discussed at this year's event. Please post your comments/questions in the comments section of this archived show. You can reach Henry Vanderbilt through the Space Access website.

We welcomed Rob Manning back to the show to discuss landing human-scale landers on Mars with supersonic retro-propulsion (SRP) or with other tools. During the first segment of our 1 hour 42 minute discussion, I asked Rob to define the problem regarding landing large payloads on Mars and to provide us with the definition of a large lander. A good portion of the first segment was a comprehensive discussion of these issues. Some of the topics included previous Mars landers, Martian atmospheric considerations, supersonic parachutes and Earth testing of them, vehicle entry mass, flying engines backwards as it is called, heavy lift, Mars landing areas and why, reusability, what is being learned from the SpaceX flyback booster reusability tests, and lots more. It was an information packed first segment and I suggest careful listening attention. In addition, you will likely find Rob's recent paper with several co-authors, "A High-Heritage Blunt-Body Entry, Descent, and Landing Concept for Human Mars Exploration" of interest and helpful in understanding the challenges for putting large payloads on Mars. You can download the paper at www.ssdl.gatech.edu/papers/conferencePapers/AIAA-2016-0219.pdf. Other topics in this segment included a question from Ralph about space advocate mission planning designs and if the actual mission planners ever pay attention to advocate proposals. Don't miss what Rob had to say in response to Ralph's question. It might surprise you. More was said about this in the second segment. Before the beak, Rob talked about the deceleration curve for g's regarding the return to Earth. He talked about how this can impact the crew and force significant design and engineering changes on the mission. In the second segment, Doug sent in a provocative email asking our guest "Might it be easier to accomplish great things in space than many assume?" Don't miss Rob's response to this question. By the way, part of Rob's response focused on the different ways SpaceX could do something and test it as compared to NASA. Later, Doug called in to ask our guest about deployable heatshields which might allow Mars landings to take place at higher up elevations. Again, don't miss what Rob had to say in response to Doug's heatshield question.Linda from Las Vegas asked for more information about the differences in landing large payloads or humans on the Moon or an asteroid compared to do it on Mars. Rob had much to say about EDL for all three destinations. Near the end of our discussion, our guest was asked about space advocate papers for planning missions or engineering and if such papers or proposals were considered by those actually doing the mission. Rob talked about the need for such papers to have some sort of critical feedback for the author as technical criticism is essential.

We welcomed back John Strickland for the third part of his three part series. For the third in the series, John focused "on Mars operations with high mass expeditions and robust bases, using the Oberth effect to massively lower propulsion needs for Mars. This also covered aero-capture, how to reduce propellant mass and increase expedition mass, base-first policy, crew safety, new interest in reusable ferries, and much more." During the first segment of our 97 minute discussion, John started out by talking about how to get to Mars, the use of cislunar infrastructure, especially at L1, and the use of multiple expeditions. Much of what he talked about in this segment was technical, especially when he addressed km/second needs for orbit, launch, orbit, landing. He was asked about ISRU by Dr. Doug so he spent time discussing that. Near the end of the segment, he was asked if he had a Power Point or otherwise written document summarizing what he was talking about as that would probably make following the discussion easier. He referred us to his 2011 publication which is on the NSS website, ACCESS TO MARS: (Part 1) EARTH TO MARS TRANSIT LOGISTICS ALTERNATIVES, an ISDC presentation from May 18-22, 2011. You can follow along by using this 109 slide document, www.nss.org/settlement/mars/AccessToMars.pdf.
John discussed getting to the Martian surface with cargo as well as with humans, the use of different fuels, robotic missions and uses, ISRU, aero-capture, and even the use of advanced propulsion such as Vasimir. He also talked about his space ferry idea. In the second segment, we started with a question from BJohn about crew safety, suggesting that a "crewed Mars lander will carry its ascent stage fully fueled, and not use ISRU. This gives the crew the option to abort to orbit anytime during the landing sequence." John did not agree with his suggestion and explained why his plan provided better safety than what BJohn was suggesting. What do you think? Post your ideas on TSS blog. About seven minutes into the second half, John stopped the discussion to answer his cell phone. This provided an interesting first of a kind break on The Space Show as we heard John's side of the conversation. Moving on after John's phone call, Doug emailed in a question about John's reliance on reusability when it was yet to be proven. See what you think of John's reply. Again, let us know by posting your thoughts on TSS blog. John explained the Oberth Effect and "swing by maneuver." Doug sent in a follow up question asking John how long he suggested crews remain on Mars. John said around 500 days but it would depend on the transfer back to orbit. He then talked about both a conjunction class mission and an opposition class mission. In addition, he referenced zero boil off conditions or ZBO.

We welcomed Dr. Mike Griffin back to the show to discuss US space policy and much more. In the first segment of our 92 minute program, I asked Dr. Griffin for his view of US space policy per his recent House Science Committee testimony. We spent most of the first segment talking about our space policy now and for the future. One point that our gust made related to the ISS and the fact that we should continue using it but most of all, we should be planning on the continued use of the station. He said given how much time it takes to plan and finance space experiments, many potential ISS users won't make the investment given the long term use of the station is in flux. He made the case for continuing with the ISS and making that part of our policy to drive even more experiments and use of the station. Our guest then proceeded to outline three separate steps which he said should constitute our space program moving forward. See what you think of his three steps, then post your comments about them on TSS blog. Before leaving this subject, I asked how we would finance the robust space policy and program he was talking about. Again, don't miss his response to this question. What do you think? I asked our guest the same question I have been asking many other Space Show guests and listeners which was what was in it for the American taxpayer to finance the extended space policy and program he was advocating. Mike's response might surprise you. He focused on establishing American pre-eminence and what that would mean for each of us. He also talked about updates to our industrial capability along with our way of lie. Mike said that 70% of a Americans support space but obviously they don't dwell on it as we do in the community. Jeff from Tucson sent in a question asking about safety for crew and cargo regarding SLS which does not separate cargo and crew as did Aries 1 and Aries 5. Mike had much to say in response to Jeff's question so don't miss his comments on crew safety. Jack, referring back to Mike's testimony, asked about space settlement and why it seemed that at the hearing, there was no interest in settlement. Mike disagreed and said the difference was more semantics than anything else as they spoke to having a permanent presence on the Moon and elsewhere in the solar system. By the way, if you want to see the House Science Committee hearing, visit www.youtube.com/watch?v=Zebh4UXovq4. Robert Jacobson sent in a note asking about reliable economic and investor information for making space investments. Mike said it was very difficult to get accurate financial, economic, and investment information in space investments. He also provided us with his opinion and thoughts on the new interest of venture capitalists in investing in commercial space companies and sectors.

Chris Carberry, Rick Zucker, Monday, 3-21-16 (20.64MB; download) -- Guests: Chris Carberry, Rick Zucker; Topics: Humans two Mars, the Explore Mars, Inc. upcoming summit, Affordable Mars Workshop & more. Please direct all comments and questions regarding specific Space Show programs & guest(s) to the Space Show blog which is part of archived program on our website, www.thespaceshow.com. Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use.

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed Chris Carberry and Rick Zucker to our 90 minute discussion. During the first segment, I asked our guests about three recent topics discussed on The Space Show that were relevant to humans going to Mars. The three topics included planetary protection, why go to Mars first rather than learning and proving out technology by first returning to the Moon, and where was there a viable policy for humans to go to Mars? We spent most of the first segment addressing these three areas. On the topic of planetary protection, Chris had some interesting things to say. The subject is taken seriously, it is continually discussed and he and others see it as an evolving issue. He believed that there would have to be risk adjustments and modifications as more information about humans to Mars becomes known. He also said that were humans permitted to go to Mars but only to places of little or no interest, one would have to determine if it was worth doing a human Mars mission to such a location. This was a fascinating discussion, don't miss it. As for the Moon, as I said to Dr. Benaroya on Sunday, Mars advocates do not see the Moon as an essential first step for going to Mars. While Mars first advocates do not oppose going to the Moon, they say by landing humans on the Moon, the risk is that the program to Mars gets sidetracked, maybe even for decades. Chris advocated cislunar development without landing on the Moon. As I suggested to our Sunday guest, Mars first advocates believe that if the goal is to go to Mars and they say that is the goal, then one should go to Mars, not some other destination.
Regarding the absence of a Mars policy, both Chris and Rick talked about how the issue for humans to Mars has been improving along with more and more interest in congress as confirmed by their recent legislative blitz. Our guests also referenced the upcoming third edition of the Affordable Mars Report, out in about two weeks, as further evidence of a humans to Mars policy that is evolving for the better each year. During this segment, our guests talked about the upcoming Humans 2Mars Summit planned for May 17-19 at GWU in Washington, DC. Several of the main speakers and events were discussed. You can find out more about this event and the free streaming of it by visiting http://h2m.exploremars.org.
Before the segment ended, Bonnie in Atlanta wanted to know if Explore Mars was reaching out to the presidential candidates. Our guests talked about their outreach activities in this area plus they said that after their big May event, they would have teams going to congress for more legislative educational efforts for the eventual humans to Mars mission. The final questions of the segment dealt with our TRL for going to Mars at this time, plus a time line for a realistic launch date for a humans to Mars mission.

We welcomed back Dr. Haym Benaroya to the program for a two hour discussion regarding humans to the Moon and advanced technology. I started the discussion by following up with a comment our guest made the last time he was on TSS when he mentioned he had an idea for a self-deploying lunar space elevator. I asked him to explain his idea which he did in detail. Thus, a significant part of the first hour discussion was focused on the lunar space elevator subject. Not only did Dr. Benaroya go into details, listeners with their questions did as well. For example, Kim called in suggesting a rotating tether might be a better idea. Other listeners emailed in suggestions for where on the Moon the lunar space elevator would be located. Dr. Benaroya did say his idea for a small, self-deploying lunar space elevator would be a demo model as much has to be learned about doing this prior to building a fully capable and operational lunar elevator. Don't miss this discussion which does address needed technology to make such a device happen.
Throughout our discussion questions came in about going to Mars without going to the Moon first. Haym said going to the Moon first was essential to pave the way for being able to go to Mars. He also talked about how much easier it would be to go to the Moon over Mars, suggesting the challenges for taking humans to Mars are too big for us at this time. He mentioned that only 50% of the spacecraft sent to Mars were successful and none carried humans on board. He also said astronauts did not make good construction workers so we to develop 3D printing technologies, inflatable structure and more by first doing so in an "easier" environment on the Moon. Radiation shield came up and this was also a topic Dr. Benaroya addressed in some detail. He questioned why Mars first advocates have their positions and thought some might not really believe what they are proposing. I gave him my impression of the Mars first advocates based on my interviews with them over the years. I think they believe that if Mars is the goal, Mars is where we go. End of story.
One of the big topics of the first segment came about due to Joe's email question asking Dr. Benaroya if he was at all optimistic about our doing some of the lunar things he was talking about given the current lack of US policy, leadership, and our economic conditions. Haym provided an answer to Joe's email question but so did others. Dr. Doug sent in a very good email reply but I was unable to read it until the second segment. See what you think of this discussion and let us know with your blog comments.
In the second segment, John from Ft. Worth called to discuss the lunar space elevator and the use of autonomous lunar structures. John and Haym also had a discussion about private funding for missions versus public mission funding.

John Batchelor and I welcomed Dr. Lyle Whyte, astrobiologist from McGill University, to discuss the recently launched joint Russian and ESA ExoMars mission to Mars. We discussed the instrument package including the Trace Gas Orbiter and the definitive search for and analysis of methane on Mars. Dr. Whyte described the ExoMars drill which can penetrate up to 2 meters in the Martian surface and they hope to find using this drill. We talked about the Schiaparelli EDM lander, the choice of Oxia Planum for the 2018 ExoMars mission landing site, and the division of responsibility for the mission between the Russians and ESA.
