We welcomed back Ken Murphy to discuss space current events, his coming articles and stories, and reasons for returning to the Moon and developing cislunar space.  During the first segment of our 2 hour 2 minute discussion, Ken started out by telling us about his upcoming Jan. 4, 2016 Space Review article regarding the July 2016 Moon Day celebration in Dallas.  He provided the logistical details for the event throughout our discussion, plus he described the event, the Lunar Sample Bags, the educational outreach, and their ham radio connection to the ISS via the ARISS Program.  This discussion was followed by our talking about the SpaceX Falcon 9 launch and first stage recovery.  Ken then talked about making significant changes in NASA to advance space development, especially getting younger employees at NASA with an average age in the 30’s by getting rid of the older NASA employees.  This comment caused John from Ft. Worth to call to remind Ken of anti-age discrimination laws, wondering just how Ken would get rid of the older people at NASA.  We shifted our discussion to cislunar development and international lunar development efforts.  We talked about the need for public private programs to do cislunar and lunar development.  Betty emailed Ken to ask him if he thought all the lunar advocacy made a difference and helped the cause of our getting back to the Moon.  Ken’s response to Betty might surprise you so don’t miss it.  Before the break, we talked about education and the public’s space educational level.  You definitely want to hear what Ken said about the average person’s space knowledge and teachers in our K-high school grades.  Tell us what you think about Ken’s education and teacher analysis and comments by posting your thoughts on TSS blog.

In the second segment, we talked about going back to the Moon, then Ken brought up lunar dust issues, then in response to the typical Moon or Mars question, he said the Moon was our sand box made to order to train us for solar system exploration and even settlement.  He also said while he is interested in Mars and space settlement, his near term focus was on cislunar development and returning to the Moon.  During our program, he often referred to talks he has given to the general public so he talked at length about both space and STEM being a hook for getting young people interested in space and the STEM topics.  He again mentioned that on Moon Day, they would be talking with the ISS crew via the ARISS program,.  Preston from Chicago asked him if he had seen The Martian or the latest Star Wars movie.  His response and what he said about the movies will have to be a surprise for you.  Near the end of the program, Jerry asked him about his support for advanced propulsion and Jack asked him what he thought of Elon’s plans to go to Mars in 15 years or so.  Ken was also asked for his opinion on space solar power and about using water ice on the Moon for fuel.  Ken said it would be better to work the Moon from L1.  In conclusion, he offered us a good takeaway message and a good set of closing statements you will want to hear.

Make sure you post your comments/questions on TSS blog.  You can reach Ken through The Space Show or The Moon Society (www.moonsociety.org).  Finally, Merry Christmas everyone.  The Space Show team and I wish you a very good holiday season.

We welcomed Dr. Paul Spudis back to the program for a 2015 space year in review. During the first segment of our 1 hour 31 minute discussion, we covered much ground reviewing key events of 2015 including European, Russian, & Chinese space accomplishments & missions. Dr. Spudis got several emails on a wide range of topics from space advocate rhetoric to Orion, CST 100, Dragon V2 and more. Regarding advocate mission plans and projects, he said the technology people talk about and want to use in their various space mission designs does not really exist. He used going to the Moon to harvest water ice for water and fuel as an example of where we are today. That said, he indicated that there are only so many wants to do certain types of space projects so it was likely that which advocates called for could end up in actual mission plans and real projects. Budget issues were also discussed as well in this segment. Listener Christa asked if the return to the Moon and cislunar development will become a future policy priority. Dr. Spudis had much to say on this topic so don’t miss it. This included the possible impact of the 2016 presidential election on space policy. Jeff in Boston inquired about the aging process and other human factors as challenges/obstacles to doing BLEO projects. Dr. Spudis offered us an interesting perspective on the human factors issues. Jack in Portland inquired about our guest’s views on asteroid mining and the language used in the new commercial space law recently signed b the president. Our guest shared his views with us on these issues. We talked public-private partnerships and government procurement. Kim called from Mexico to inquire about the Lalande Crater on the Moon & the cracks or fissures seen in the photos, plus impact melt and more. She also talked about young and old craters which Paul defined for us upon my request. A young crater would be less than a billion years old! Near the end of the segment Paul talked about the challenges in closing a business case for going to the Moon at this time, plus the proper role for government in this situation. Sandra asked about the lunar space elevator.

In the second segment, Kim called back to inquire some more about Lalande crater, thorium bright spots, and more. BJohn emailed in asking about lunar landers, then Rodney brought up space settlement. Paul had interesting comments on space settlement you will wan to hear. A good portion of the second segment was spent on Mars. Back to the budget, he said the challenge was to do more in the most efficient ways possible while reducing the need for more funding. The Mars-Moon debate came up again with Paul explaining why returning to the Moon before going to Mars was important Solar power for missions and habitats was discussed along wit ISRU usage. Don’t forget to reach Paul’s article on Air and Space about the asteroid mining section in the Commercial Space Law just signed into reality by President Obama. See Paul’s writings at www.airspacemag.com/author/paul-d-spudis/?no-ist as well as at www.spudislunarresources.com. While there, check out his “Close but no Cigar” article we discussed on air (www.spudislunarresources.com/blog/the-new-space-resources-law-close-but-no-cigar).

We welcomed back Dr. Jim Dewar to the show to discuss his plans for the use of nuclear rockets specifically from Earth to LEO.  In addition, Jim’s book (it is out of print) “The Nuclear Rocket: Making Our Planet Green, Peaceful And Prosperous” is being made available as a Space Show fundraiser and we thank Jim for this great gift.  You can get a new paperback autographed copy of this book for a $50 contribution to The Space Show.  Please make your contribution using Pay Pal on TSS or OGLF websites or mail a check to TSS as instructed on the donation page of the websites.  Also, send me an email telling me your $50 contribution is for Jim’s book, provide your full name and your mailing address.  I need this email to know you want the book in exchange for your donation.  As of the time I am archiving this show, I have only ten remaining copies of the book to give away so act fast as once they are gone, this offer ends.  During the first segment of our two hour show, Dr. Dewar outlined his plan to break the nuclear rocket ban on using a nuclear rocket from Earth to LEO.  Jim spent some time explaining the history behind this ban which is not law!  The ban came to be in 1960 as a result of a luncheon meeting.  Listen to his telling of this story.  Do you find all of this frustrating?  I asked Jim how nuclear propulsion would work from Earth to LEO.  As you will hear, he said it was applicable to second or third stages on the rocket, not the first stage of the rocket.  He explains this in detail so don’t miss it.  Most of the first segment was devoted to discussing this ban, the early nuclear rocket history and tests, questions about the Soviet Union nuclear rocket program, the U.S. Congress, and cost comparisons with chemical rockets figuring in the cost for permits, dealing with protestors, time delays, etc. Jim also explained the economic benefits of his unique public private partnership he wants to see created to do nuclear propulsion to LEO and why.  His methodology for making this happen is potentially doable.

In the second segment, we continued talking tech about the nuclear rocket including core issues, the possibility of gas cores, specific impulse for the NTR, then a question came in about supporting the NewSpace agenda of NASA supporting space settlement and low cost space access.  He was asked if the NTR plan he was proposing supported these NewSpace goals.  Don’t miss what he had to say about this as I believe it was an important part of the discussion.  Jim repeated often during the show that as a nation we were nearly $20 trillion in debt and bankrupt. He then explained the economics of his program and why they would benefit NASA and the country in this challenging economic time rather than be deleted as a program that was just too costly.  Quite the opposite, he stated his program was made to order for these tough economic times.  See if you agree.  I do and we talked about it some more at length as we neared the end of our program. I suggested a sales approach that was much broader than just the space industry.   John in Ft. Worth called to discuss many technical issues and core temperatures.  BJohn wanted to know if the NTR should be reusable and refuelable.  Joe wanted to know how to start the program to advocate the public private partnership Jim was talking about and which he fully describes in his book.  Comments came up regarding Dr. Zubrin and the nuclear salt water rocket,  (see http://path-2.narod.ru/design/base_e/nswr.pdf).  Near the end of the show when we were talking about creating the needed policy for the partnership, Dr. Dewar referenced Admiral Rickover as a model for the type of leadership needed to make the NTR project happen.  As the program was ending, questions came up about Thorium and U233.

Please post your comments/questions on TSS blog per above.  You can reach Dr. Dewar about his first book or anything else through me at drspace@thespaceshow.com and I will send you his email address or forward your note.

We welcomed back Jim Keravala, COO of Shackleton Energy Company, to update us on the latest news with Shackleton and their lunar plans. Visit their website for more information, www.shackletonenergy.com. During the first segment of our 1 hour 47 minute discussion, Jim introduced us to the Shackleton Energy plans for space development by solving the terrestrial energy problem facing Earth. The program Jim outlined is expansive and at times complicated so you will want to pay extra careful attention to our discussion. Jim talked about creating the Off World Foundation and the Off World Consortium which he fully explained in this segment. He also said the real path for space development required solving the earth’s terrestrial energy problem. He then explained his multi-billion dollar program which is in three phases starting with propellant depots, then lunar mining and manufacturing, followed by the establishment of space based solar power. Our guest talked about the many challenges but noted that investor caution was prevalent along with risk uncertainty. In this segment, he talked about the market, consortium participants, timelines, business and industrial challenges, and more. He also outlined the assumptions used in designing this program.

 

In the second segment, Jim talked about the Outer Space Treaty, regulatory barriers, rectenna placement, power distribution to the poorest and most needy of countries first, space advocacy, space settlement, the traditional space industry, and technology readiness levels (TRL) for the development of Off World program. Jim answered questions about program costs, suggesting that the first phase mentioned earlier would cost around $18 billion! He outlined the additional program costs and timelines, plus revenues received along the way being reinvested in the program. We talked about comparisons with other industries such as the oil and gas industry and their support for the Off World program. Several times in this segment Jim said this was the best way to drive the development of space and eventually space settlement. At the end of the segment, Jim offered a detailed conclusion & summary for the Consortium to solve the issue of terrestrial energy through the use of space.

 

Please post your comments/questions on TSS blog above. You can reach Jim Keravala at the email address he gave us at the end of our program.

We welcomed Dr. Lewis Dartnell to discuss his book, “The Knowledge: How To Rebuild Civilization In The Aftermath Of A Cataclysm,” then applying it to starting up a space settlement regardless of where the settlement might be located. During our 68 minute discussion, Dr. Dartnell started out by giving us the background to his having written the book, some of the applicable constraints for the book, and that it was written for terrestrial events though there were ways to extrapolate some of it to space settlement issues. Dr. Dartnell explained what it would take to reboot civilization depending on why it was destroyed. He listed three possible sources of destruction. One was a viral epidemic or pandemic, another was nuclear war, and another was being hit by a large asteroid or something similar. He also said it might be easier to reboot after a pandemic because infrastructure would still be standing and largely available for use whereas with the other two, destruction would be overwhelming. We talked about skill sets needed to reboot, then we talked about the minimum size for a new community to start over. Here we extrapolated to space, exploring what it would take to start a space settlement. The initial numbers were high but not as high as what would be needed later on. The need for genetic diversity was also high. Several times he referred to needing more women than men for breeding to seed the new settlement, but without genetic diversity and in light of possible in-breeding to get the early numbers up, generations of humans might be born that were genetically weak and that could be a problem. Genetic diversity, needing more women than men, microgravity and radiation issues were just a few of the challenges for the new space settlement. Past the initial number to get the settlement going, to sustain it there would be a need for thousands in the community. You don’t want to miss this discussion as it was an eye opener. Don’t miss why he said he would rather start a new Earth settlement even after a horrific cataclysm than a Martian settlement. He said the Earth settlement would be far easier no matter what the challenges than the Mars settlement. Dr. Dartnell then talked about the possibility that someday an Earth-like exoplanet would be discovered so we compared starting a settlement there as opposed to Mars. To make this comparison, we zeroed out all issues relating to space transportation. You might be surprised by what Dr. Dartnell concluded. Later we compared a lunar settlement with the other two. Much of our discussion revolved around the fact that Earth was and is habitable and even after the horrific event, would remain habitable. Mars is not habitable nor is the Moon. That fact alone is a huge contributor to complexity and challenges. Listeners emailed and called to ask Dr. Dartnell questions ranging from the number of skilled people needed to start a space colony to having sperm banks in space for the genetic diversity required for the new settlement to how free floating habitats might be different in their requirements as compared to planetary settlements. Questions were asked about the problems resulting from human exposure to unfamiliar biology, human contamination of the planet, and the planet contaminating the humans. These were all interesting discussions so you definitely want to hear the full 68 minute program.

We welcomed Dr. Julie Robinson, ISS Chief Scientist, to the program. During our 71 minute discussion, Dr. Robinson provided us with an overview of science on the ISS, specifically identifying two goals: 1: Research for BLEO; 2: Developing LEO for long term space use and for benefiting life here on Earth. We discussed the logistics of science on the ISS, the ISS international partnership and how ISS resources are allocated to the partners for science as well as other projects. Our guest further broke this down between Russian and the U.S. and then said that for the U.S. segment, the U.S. has about a 76% usage allocation of ISS resources. We talked about the science done on the ISS, the mix with government and commercial projects, then we started talking about the 1 year study with the Russian cosmonaut and American astronaut while at the same time doing the Twin Study with astronaut Scott Kelly on the ISS with his brother Mark Kelly here on the ground. Dr. Robinson spent much of the balance of our interview time going into the specifics of these concurrent studies, the investigation categories for each study, and more. Our guest fielded questions about the length of time for the study being fixed at one year rather than being longer and objective oriented. As you will hear, ISS logistics, using the Soyuz as a lifeboat, and the overall ISS operations and other experiments going on all contribute to why a one year study was settled on rather than a long duration study or one based on achieving certain accomplishments or objectives. Dr. Robinson talked about the possibility of future studies given that they anticipate issues and information from this first study suggesting more refined studies to be undertaken in the future. Listeners emailed our guest several questions including asking her about the assumed low science productivity on the ISS, a statement Dr. Robinson refuted with evidence. BJohn also asked about low gravity issues. Later, in a follow up question, BJohn asked about a Phobos mission and doing human spaceflight mission simulations on the station. Don’t miss Dr. Robinson’s response to these questions. Dr. Bill Rowe called to talk to her about CO2 buildup, oxidative stress, EVAs, and possible magnesium deficiencies in astronauts while in space. We talked radiation issues, the OSHA rules for maxing out on radiation, and finding astronauts for the long mission that would not be disqualified due to the OSHA radiation rules. Vision problems, fluid shifts and other complications were discussed throughout our interview with Dr. Robinson. A listener commented that both participants in the 1 year study were men and wanted to know about gender differences which Dr. Robinson addressed. Another listener wanted to know about shared access of the information and if it would be made available to the commercial industry, the space tourism industry, even Mars One as an example. Later in the segment, Dr. Robinson went into much more detail regarding the investigation categories for both the 1 year and the Twin Study. When talking about fluid shifts, she was asked about differences in the Russian approach as compared to the American approach. One example that she provided us was the Russian use of their Chibis suit which sucks fluid back down to the legs. In making additional points in reference to space settlement questions, Dr. Robinson talked about comparisons with space to early oceanic exploration and said that people are not living at sea for their entire life even today. Don’t miss this discussion. Based on other questions, the human gravity RX was discussed along with the use and challenges regarding centrifuges in space, alternative propulsion to get to a destination much quicker, and the fact that even a low gravity body is better for people than no gravity. Again, don’t miss the discussion. We talked more about behavioral studies, Dr. Doug asked a series of three questions that took us through to the end of our program with other listeners asking questions in-between Doug’s. For example, cognitive issues came up as did timelines and influences to making rapid research progress including money and financing. As we were about to end, I did ask about genetic screening, experimentation, and modification. Don’t miss what our guest had to say about this and why. As we were ending, I inquired about research plans once the ISS was deorbited. Again, don’t miss the options that were discussed with us. Dr. Robinson left us with thoughtful concluding comments you will want to hear, plus she provided us with the social media contact information to follow ISS research on a regular basis.

Please post your comments/questions for this show on TSS blog above. You can reach Dr. Robinson at NASA or through me.

We welcomed Michael Mackowski to The Space Show to discuss his book “Adventures in Space Advocacy,” space advocacy in history through to the future, spacecraft model building and much more. During the first segment of our 90 minute program, Michael talked about growing up as a “child of Apollo” and being inspired by our early space program. He went on to get an EE degree and to work in the industry. He said it was an exacting time, especially when the Galileo Jupiter mission finally happened. He talked about the start of organizations such as L5, The Planetary Society, AIAA, and his own early ventures into space advocacy which are detailed in his book, available at Amazon at www.amazon.com/Adventures-Space-Advocacy-Personal-Activism/dp/1511564911/ref=tmm_pap_swatch_0?_encoding=UTF8&qid=1438189701&sr=8-1. He talked about moving, heading to Phoenix and engaging in space advocacy once again after a brief pause when he was in Washington, DC. This led us to a discussion about individual advocacy efforts as compared to group or organizational efforts. Michael was asked how he has sold human spaceflight to a general audience, his most receptive audience, and lobbying congress. Our guest spent some time discussing the challenges in advocating human spaceflight to the general public so don’t miss this discussion. Space tourism came up as a probable kick starter once the industry starts commercial operations. Michael thought that space tourism could provide a crucial boost for industry support even outside the space community.

 

In the second segment, we talked about Michael’s interest in spaceflight models. If you visit his website, www.space-city-mike.net, you can click on scale models on the right side menu bar (http://space-city-mike.net/modeling). Michael described the industry, licensing challenges, specialty model builders and more. He also talked about using models in the form of make and take kits when talking to young students about space. Model building through 3D printing was discussed, then I switched the topic to inquire about his success in outreach with adults and children. He said 5-7th grade was the best group to talk with as high school was probably too late. As for speaking to adult groups, he said it was usually about entertainment but that it seldom produced advocacy action on the part of the adults hearing the talk. I seconded that experience given my talks with adults on space this and that. Near the end, we talked trends, the increasing influence of social media, passion, and connecting pace to our future.

We welcomed Rex Ridenoure back to the show to discuss Ecliptic Enterprise, LightSail, the NewSpace Conference & more. During the first segment of our 1 hour 33 minute discussion. I started our discussion by asking Rex how Ecliptic got the LightSail contract from The Planetary Society. Rex relayed the story to us of their involvement with LightSail & I am sure you will find it interesting. This discussion led Rex to update us on Ecliptic activities with their size reduction program for their avionics and their work on cubesat projects. Rex talked about their customer and project base and why they don’t have foreign launcher contracts or relationships. ITAR!! He talked about their having been denied ITAR clearance in the past so they don’t even bother obtaining it anymore. Rex talked about some of their camera space projects including LCross, transmitting data back via the DSN and the limitations because their cameras could work all the way to Pluto and beyond but the data transmission rate and capacity to do that for video is not available. We then returned to the LightSail project which Rex described in some detail during the balance of our segment. Rex also has suggested we read the blog articles on LightSail via Jason Davis on The Planetary Society website. www.planetary.org/about/staff/jason-davis.html and look for his posts on LightSail. By the way, it is an excellent blog and I recommend you add it to your regular reading list.

 

In the second segment, Rex provided us with an overview of the SFF NewSpace Conference and I totally agreed with what he said having also attended it. In my opinion, it was the very best of all the SFF-NewSpace conferences I’ve attended since the late 90’s. As part of his summary of the conference, I asked his opinion on the Dr. Linda billings Scientific American article that attacked SFF, NewSpace, space settlement, etc. Here is the article in case you missed it: www.scientificamerican.com/article/the-inexcusable-jingoism-of-american-spaceflight-rhetoric. Let us know on TSS blog what you think of Dr. Billing’s article and what Rex had to say about it. Please be respectful and civil, no name calling, even if you strongly disagree with either Dr. Billings or Rex. Since our show ended, Shubber Ali, the original Space Cynic, posted a reply to Dr. Billings on the Space Cynics website. Check it out as I will add all of this to the Open Lines discussion for Sunday, August 2: https://spacecynic.wordpress.com/2015/07/27/the-inexcusability-of-poor-reading-comprehension. As the show neared the conclusion, Rex summarized key points & highlights of discussion.

We welcomed back Al Globus to discuss his plan for LEO space settlement about 500 km above the equator to minimize radiation, shielding, and to improve the mass ratios to make settlement easier than in other locations.  During the first segment of our 1 hour 49 minute program, Al put forth his hypothesis that radiation over the equator was very light meaning that any space settlement would need minimal shielding or possibly no shielding.  This vastly improved the economics of developing and resupplying the settlement given its close proximity to Earth and the lower mass needed for the settlement and transportation.  This would be a “free space settlement” meaning it would be in orbit.  During this segment and the entire program, Al explained the radiation issues but you should read his paper on the subject, “Space Settlement the Easy Way.”  You can find this paper at http://space.alglobus.net/presentations/Easy.pdf.  Al spent lots of time explaining the radiation issues and talking about the initial settlements which may not have an economic purpose.  Al did go into the technical side of the radiation issues and his analysis for this location so don’t miss what he had to say about it plus as I suggested above, be sure to read his paper.  Later in the segment, he brought up space tourism and space hotels as a type of initial space settlement but one that would pave the way for actual settlements in LEO.  In the end, Al said that a LEO settlement is an easier way to get started with space settlement but stated many times that even a LEO space settlement above the equator would be challenging.  He did get several listener emails, some of which challenged his radiation analysis and the idea that little or no shielding would be necessary.  Al was also asked about space exploration but he was very clear that he was focused on space settlement.

In the second segment, we talked space policy, the U.S. congress and even the issue of space debris removal.  Marshal called to talk about radiation shelters from solar storms, Alexander wanted to know more about space solar power.  Adrian sent in a series of notes challenging Al and using the December 2004 Magnetar event.  Al was not familiar with it.  I inquired of the listeners to tell us what happened to the ISS during the event.  After the show, I got a follow up note from Adrian regarding the event and the ISS:  “Thanks to the magnetar’s great distance, the super flare posed no threat to humanity or Earth’s biosphere. The International Space Station was on the opposite side of Earth when the flare hit our planet, but even if the astronauts had faced the full fury of the blast, they would have received a radiation dose less than a dental X-ray. An SGR super flare’s pulse of high-energy radiation could seriously damage a planet’s atmosphere only if it occurred within about 6 light-years, according to Adrian L. Melott (University of Kansas)”  See more at:www.skyandtelescope.com/astronomy-news/the-brightest-blast/#sthash.VvmrtqKH.dpuf & www.skyandtelescope.com/astronomy-news/the-brightest-blast. I believe the point Adrian was trying to make was that no shielding even for a LEO settlement above the equator leaves the occupants w/o protection in case of an unexpected radiation related event. To this point, Al spent some time talking about risk and risk taking. Toward the end of the program, Al brought up the subject of space mining, Biosphere 2, and the size of the space station. During the show he also talked about artificial gravity and increased spin rates for people at 4-6 RPMs.

We welcomed back Dan Adamo to the show for this 2 hour 36 minute comprehensive discussion regarding HSF to Mars, the Second Mars Affordability and Sustainability Workshop report and much more.  During the first segment of our program, Dan started out by telling us the process used to engage him reviewing said report and writing his critique of it which is on The Space Show blog (https://thespaceshow.wordpress.com). Topics discussed in this segment included the use of Low Latency Telepresence (LLT) as compared to High Latency Telepresence (HLT), the absence of human factors and aerospace medical personnel in attendance and said issues missing from the workshop report.  Dan said the key missing information included radiation as well as microgravity concerns.  Dan then questioned the existence of a compelling rational for humans going to Mars.  This became a recurring discussion topic throughout today’s program.  Space settlement came up & so did a possible space race with China.  The subject of a rescue mission came up but there was a detailed rescue mission discussion near the end of the program in the second segment.  Dan was asked about the minimum crew size to operate an LLT program from Deimos or in orbit around Mars.  Several emails were sent in including one by Dr. Jurist addressing high acceleration upon return from Mars.  Dan then suggested the stepping stone approach, starting with cis-lunar space.  Doug sent in questions about heavy lift versus using already large commercial rockets.  Dan and Doug discussed this, then later in the second segment, Doug asked more questions on this topic.  For now they talked about going to Deimos with a Falcon Heavy.  Dan pointed out the need for many more launches and rendezvous missions as compared to one or two SLS type rocket launch.  He questioned if we can’t afford SLS launches, how do we afford even more launches and rendezvous missions.  Marshal emailed us wanting to know about the possibility of lava tube plans .  BJohn asked this guest about a possible Mars cycler & then we moved to the second segment.

In the second segment, I asked Dan what he thought the impact on space policy might be vis a vis the workshop being discussed on this program.  Don’t miss his reply.  Doug asked a question inquiring if for the same cost it would take to send humans to either Deimos or to the Martian surface, one could send many high-latency rovers to multiple locations far from each other to give the rovers many chances to discover evidence for life in different types of places?  This brought us several exchanges comparing LLT with HLT, heavy lift versus smaller rockets and more.  Doug and Dan has several exchanges during this segment, especially when the topic of rescue missions came up.  Ted in Boston asked about the rational for going to Mars, referenced the recent program with Dr. Zubrin, and the payoff or benefits for a human Mars mission.  Dan had much to say about this so don’t miss it.  John from Ft. Worth called to say we were not yet technically ready for Mars and we should use the stepping stone method and focus in cis-lunar development and exploration.  As an example, Dan & John talked about the need to know the actual gravity RX for humans. Dan said we should have a short arm centrifuge on the ISS helping to figure this out but that there was no policy to do that.  We turned to the topic of rescue and I told listeners what I found out about who pays for rescues when I did some quick and dirty research on this a few weeks ago.  The issue of rescue and how it might happen on a Mars mission or even in cis-lunar space came up with many listener emails including several by Doug putting forth various rescue scenarios.  For the most part, since we have no launch on demand, no rockets, pads or hardware sitting around ready to be used at a moments notice and we have to contend with launch windows, it does not seem feasible that a Mars rescue mission could be implemented, possibly not even a lunar rescue mission.  Doug suggested a scenario where multiple ships left for Mars at the same time and then if one got in trouble, the others could rescue the problem ship.  Dan talked about the physics and mass of what would be needed to do that. You decide if it might be feasible for such a rescue scenario to be implemented. Let us know your thoughts on the blog.  If the rescue party is already on Mars, rescue will be unlikely given the state of the art today.  Michael Listner suggested the absence of a realistic rescue plan may hinder the issuing of a launch license.  In his closing comments, Dan focused on the workshop critique saying that the sponsors would have been better served if participation had been opened up and had including human factors and aerospace medicine professionals.
