We welcomed back Dr. Chris Impey for a one hour one segment discussion about his two recent books, “Dreams of Other Worlds: The Amazing Story of Unmanned Space Exploration,” and his newer book “Beyond: Our Future in Space.” We started our discussion with Dr. Impey describing “Dreams of Other Worlds” which describes 11 unmanned space missions that have made a difference in our understanding of distant worlds. We focused on a few of the 11 missions including Viking, Cassini, Voyager, & the WMAP mission. I asked Dr. Impey what would have been included had the book been written later. The Dawn Mission would have made it, so would the Kepler Space Telescope, New Horizons, Curiosity, and probably others. We then switched to the use of ground based telescopes and here Dr. Impey talked about how many of the telescopes are being repurposed for a new life doing different types of observation astronomy. Dr. Impey was asked about his favorite missions. He mentioned Viking and the WMAP microwave telescope mission and this led to his talking about The Big Bang, dark matter, and dark energy. I asked Chris about the recent article in The Economist about the two Chicago area scientists proposing a new theory on dark matter. Chris had read the article and had some interesting commentary on it and the proposed theory. Robert sent in an email asking our guest why there have been no life detection experiments on the NASA and other planetary missions. This sparked a good conversation on the subject which you do not want to miss. Chris proposed a very plausible reason why no suck experiments have been carried out but let us know what you think by posting on the blog. Another topic discussed was planetary protection. Linda from Austin asked our guest about the UofA astronomy and cosmology programs and students, then Bill asked our guest if he had read “The Martian” or seen the movie. Chris had both read the book and seen the movie which we discussed for several minutes. Don’t miss this discussion as Dr. Impey made some interesting points about both the book and the movie and the plausibility of the story line including the initial dust storm which caused the problems for The Martian. Before the end of the program, Chris fielded some questions about future missions. We addressed the Europa Clipper mission but he said many may be disappointed for what was not being included on the mission so again listen to what he had to say. He suggested a Titan mission would be interesting. In his book “Beyond” Our Future In Space,” Dr. Impey addressed the new commercial missions & human spaceflight. Chris guided us through all sorts of possibilities for future human spaceflight. Nuclear propulsion came up with Dr. Impey having much to say about how beneficial it would be if we had it though it was still futuristic. We spoke of advanced technology & the Decadal Survey and its impact on the type of science projects that get undertaken due to funding. Will sent in a note asking about the recent article about Elon Musk wanting to get to Mars in 10-15 years given the various risks Earth faced, including extremism. Dr. Impey also said it was probably unrealistic to think that one could have a $500k ticket price for Mars, another part of the Elon Musk article. Dr. Impey offered us good summary comments so don’t miss them. The last question dealt with a possible science backlash and referenced the following Huffington Post article: www.huffingtonpost.com/entry/solar-farm-suck-up-the-sun_566e9aeee4b0e292150e5d66.

Welcome to our Open Lines show and my return to broadcasting given my post surgery recovery from my Oct. 1 spinal sugary. It was great to be back on the air. During the first segment of our two hour show, I updated everyone as to my post surgery recovery progress, I dedicated the show to the memory of our near friend Declan O’Donnell who passed away October 1 of this year, then I updated everyone on the progress being made on our new website development project and my ability to start fulfilling Indiegogo perk orders. As I stated, there have clearly been delays due to the first two weeks post surgery but we are getting back on track and I expect reasonable progress moving forward. As I explained I continue to have mobility limitations and sitting issues but things are improving all the time so I expect the delays will soon be a thing of the past. Several times during the program I mentioned booking future guests now that I am back on the air and suggested those of you that selected the co-host perk or the host your own show or be your own guest perk take advantage of the available dates for the balance of 2015 to bring your co-host guest to the program, or your host your own show to the schedule. Let me know and I will support you in invitations, etc. to get these programs booked with you even before the new website is launched. I also read an email from Matt from Switzerland who wanted to follow up from the earlier show with Ally regarding some sort of online virtual space advocacy training. If this interests you, post comments and your ideas on The Space Show blog. Matt will see them and maybe interested parties can get something going. Our first caller was Dr. Rowe who expressed misgivings about all the talk about being able to have humans walk on Mars by 2030. Dr. Row cited some of his well known and highly regarded medical research in support of his statements but as usual, committed space advocates challenged him. One was by text message to me which I did not read on air but was highly critical of Dr. Rowe wondering who he was and why in the world he would be talking about such things. Via a reply text I did tell this listener who Bill was and briefly listed his credentials for his research. I know his work is controversial and many listeners to this show do not support Bill’s conclusions but that does not invalidate his work. Doug asked Bill about running the numbers for what propellant it would take to spin up a craft with a tether long enough to get one gee but relatively low RPMs as the subject moved to needing to be in 1g and maybe even marginally less gravity would not work for humans. Lots of discussions followed about the gravity prescription issue, the need to know it for BLEO spaceflight, then Doug expressed his ideas of why it was not so important to know the gravity prescription at this time. Don’t miss Doug’s full comments on this subject and see if you agree with his perspective or not. Bill had some other medical issues to talk about, especially cardiology issues with Irwin and Armstrong. I have tremendous respect for Dr. Rowe’s work though I am not qualified to do any type of due diligence on it as I am not a medical doctor. Still, knowing it is controversial, especially with segments of The Space Show audience, I urge space cadets to be more open minded rather than married to agendas. In the end, Dr. Rowe’s work may prove more valuable and important than many think or would like to think. After a decent discussion with Dr. Rowe and listeners on related topics to Bill’s phone call, we started talking about the movie “The Martian.” This discussion took us through the rest of the show with breaks here and there for different or related topics. Everyone who called to talk about the movie like it and we did have some fun discussions about the movie and maybe some different scenarios.

In the second segment, John from Freemont, CA called to talk about the movie. he also talked about the gravity prescription and the plans by the SSI to do some sort of gravity prescription experiment. I talked about that as I have done shows on it and spoken to Gary Hudson about their efforts to fund this experiment,. He also mentioned the SpaceGAMBIT Organization which sounds very interesting. Check it out at www.spacegambit.org. June from Tucson emailed us wondering why there was criticism of the NASA Roadmap To Mars. I started answering her somewhat reluctantly but Doug called and I passed the response to Doug who handled the reply to June with a few side comments from me. In the process of talking about the roadmap, we talked about going to Phobos, cislunar development, SLS launches & much more. Doug then spoke about the movie which was the main reason for his call. During the conversation I incorrectly referenced a Dr. Lurio text to me over the weekend but fortunately Charles was listening to the show, sent me the correct text which I read on air. Charles then called the show and we had a good discussion about the movie, sci fi in general, and certain issues surrounding the movie. He also went into detail on the three items that made him see Hermes in the context of 2001. Advanced propulsion came up and several us wondered why nuclear propulsion was not a NASA solution to the rescue of the Martian. Here, we talked about the movie being about a NASA government program, not focusing on commercial or Newspace. Dr. Lurio offered a reason for this and I reminded listeners of this topic on the interview we did with Andy Weir several months ago. John Hunt called and we talked about audience and age differences with the movie. The last caller was Tim from Huntsville who saw it with friends, including non-space cadet friends. The non-space cadet friends liked the movie as much as the space oriented people liked it.

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.

Welcome to this new regular series in support of The Space Show Website & Archives Modernization Program. The Space Show will be bringing you daily short interviews (10-15 minutes each) with listeners who will share with us why they believe the new website and archival quality database will be important to them and enhance their Space Show listening experience. For the fourth of these short programs, we welcomed back John Hunt who is both an avid listener to the program, a frequent caller, and he has been a guest as well. John spoke to the need of having a guest and topic search program, including covering the early shows before 2008 that are not part of the current GuestSearch tool other than by guest name. We talked about having rebuilt the database to given the 2007 and earlier shows key words so that they would be part of our new, fully searchable, archival quality database for the archives. John was clear on the benefits and advantages to himself and other listeners with these Space Show website upgrades. John briefly mentioned having finished “The Martian” and Dr. Woodward’s book on mach thruster physics. We will hear more from him on these topics on Space Show programs.

 

If you want to share your thoughts with us on one of these short programs, we want to hear from you. Email me at drspace@thespaceshow.com and we will set up an interview time to record your thoughts on what you expect and are looking forward to with our new website.

Welcome to our Open Lines show. In the first segment of the program, I suggested a few topics and then talked about our Website Modernization Program and the new fully searchable database to deliver archival quality archives. I went over a few more of the benefits for everyone with the new site and urged listeners to not only participate in our campaign but to help spread the word through their own networks, Facebook, etc. Our support site is at www.supportthespaceshow.com and our campaign site address is www.indiegogo.com/projects/oglf-and-the-space-show- modernization-campaign/x/11584678#/story. By the way, the new site will use hyperlinks!!! John Hunt was our first caller to discuss the book “The Martian,” plus his take on Dr. Woodward’s mach thruster work given he had just finished reading Dr. Woodward’s book. John had much to say about “The Martian,” especially from a technical perspective. It is an interesting and fun discussion. His comments on mach thrusters were somewhat skeptical but he was still thinking about it and Dr. Woodward’s work as detailed in his book. He will give us a report when he has reached his “final” decision. John’s feedback on this is interesting given his knowledge of physics. He was asked what it might mean if Dr. Woodward’s work was to be verified and commercialized. He said it would be revolutionary and would open up the solar system to space travel. Near the end of the first segment, John also mentioned EM drive, the challenges for out of box theories and work when going up against science orthodoxy & related issues.

In the second segment, we heard from Jon in NJ about new uses for space shuttle main engines, SLS, and reusability which he said did not appear to be something NASA was interested in at this time given their engine use plans. Another discussion topic that came up was comparing a Return on Investment (ROI) to a Return on Exploration (ROE). I mentioned that government projects are not typically discussed in terms of an ROI and that it was very difficult to calculate a ROE because for government, that includes many things, variables, and ways of calculating outcomes. I mentioned an earlier Mars Society paper I did years ago on comparing Apollo to the school breakfast program and Hoover Dam. I addressed calculating benefits, outcomes and an economic return for each of those three projects. BJohn emailed in a comment about returns going back centuries for Mars exploration, then we got into discussing the technical knowledge and awareness of society in general. I mentioned the upcoming program with Dr. Lewis Dartnell on his book “How To Rebuild Civilization In The Aftermath Of A Cataclysm.” We talked about starting up space settlements from scratch, what it might take to be independent of Earth & how similar it might be to rebuilding a civilization after a disaster. This topic consumed the balance of the show with listener emails and calls.

Please post your comments/questions on TSS blog above. You can reach any of the callers or those sending in emails through me.

Guests:  Sydney Do, Koki Ho, Sam Schreiner, Andrew Owens.  Topic:  This program provides a comprehensive discussion of the Mars One Mission Plan by the MIT student team.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, https://thespaceshow.wordpress.com.  Comments and questions should be relevant to the specific Space Show program.

This will help me bring better programming to the audience.  We welcomed the MIT team from the Department of Aeronautics and Astronautics to discuss their paper and work “An Independent Assessment Of The Technical Feasibility Of The Mars One Mission Plan.  Download their study at http://web.mit.edu/sydneydo/Public/Mars%20One%20Feasibility%20Analysis%20IAC14.pdf.  You can also download the Reddit discussion mentioned in the second half of our program at http://www.reddit.com/r/Futurology/comments/2irk1u/mit_study_predicts_marsone_colony_will_run_out_of.  In addition, check out the MIT Strategic Research Engineering Group at http://strategic.mit.edu.  During the first segment of our 1 hour 49 minute program, Sydney started with background on why the team undertook the Mars One Mission Plan analysis, told us their goals and objectives for doing the analysis, and the role that each team member played in examining the Mars One Mission Plan.  We addressed most of the issues brought to our attention by the MIT study, many in great detail.  We also asked the team about their feedback from the space community as well as Mars One. So far, they have not been in touch with Mars One though they did ask Mars One for information in doing their analysis but no reply was received.  What they have heard from Mars One to date has been through third party reports.  On the other hand, the public’s response has been both very good and helpful.  You will have a better understanding of this and the open source software the team used when you listen to Kirk’s call at the top of the second segment.  The MIT team did not seek out or interview any of the Mars One mission volunteers, advocates, or supporters.  Much was said about Mars One website claims that their mission could be done with current technology including technology used on the ISS.  The MIT team took a hard look at these claims and then evaluated the claims which fell short.  They explained the technologies, the TRLs, and why they fell short of Mars One claims and needs.  We also talked about the ever increasing launch mass every two years with a new crew, supplies, etc.  They showed how this was not sustainable and why.  We talked about the very high number of launches needed before the first crew ever got to Mars plus the increasing number of launches needed at each two year launch window using the Falcon Heavy and a modified Dragon as suggested by Mars One.  The number of launches and their close-in interval has never been done before, even on a global basis.  We talked about making parts on Mars with 3D printing but noted that was not a current technology but that it would evolve over time with no time line available as to when 3D printing could reduce launch masses on the resupply missions.  Much was said about growing crops on Mars, separating the crop environment from the human environment and why, the need for much larger crop space than suggested by Mars One, plus a host of other critically related issues revolving around CO2 and O2.  As you will hear, the logistics of the Mars One settlement are complicated, costly, and very challenging.  The MIT team also determined that it might prove cheaper to bring food up from Earth rather than trying to grow the needed food supplies on Mars.  The MIT team pointed out that the one way mission not only made the Mars settlement far more complex but significantly more costly given it does not have an ending point.  During both segments, our MIT guests pointed out many of the assumptions in play by Mars One, where they were able to work with Mars One assumptions, and when they had to go to the literature, including NASA, to work the problem.  In this segment, I asked out guests at what point would the Mars One settlement be independent from Earth.  Their answer might surprise you.  As the segment closed, a listener asked if they had read the book “The Martian” and what they thought of it.  A few team members had read it & they liked it.  Listen to what they said about that type of survival on Mars and how missions were plan to avoid such a predicament.

 

In the second segment, Kirk was first up with his call from Trinidad.  He talked about the plant models and open source files and the error the MIT team made which they briefly mentioned in the first segment.  This relates to a flaw in the open source program dealing with CO2 and O2.  It’s a good discussion which also took place offline with Sydney and Kirk.  The MIT team is working this problem and error.  This is important so do pay attention to the discussion with Kirk.  Food systems were talked about again with the team suggesting the colony would be better off bringing food from Earth.  INSITU Resource Usage was talked about as well as sustainability issues to get the settlement up to 12 people over several years.  Tim called in asking about a Mars One analog here on Earth and what drove the costs so high for Mars One.  Again, we heard the one way mission was a huge cost driver.  Tim also asked if the costs would be the same for a lunar settlement.  Surprisingly, our guests said the costs would be similar if the lunar settlement was a one way project as the same type of issues would then have to be dealt with just as is the case for Mars.  Our final call was from John in Montana who applauded the team for their realism.  He mentioned that the health of the crew on Mars was not considered but assuming the crew is healthy when it lands on Mars and can live their, as people age, their medical care and costs rise.  As we heard, no such analysis was made or considered for these issues or their ethical component which the MIT team brought up.  Here we learned that the main assumption was a healthy crew from landing on Mars all the way through the Martian settlement process.  Such an assumption is not realistic but to do the analysis, one has to decide at what level an illness or injury will be treated and at what level crew members will not get treatment.  As the team said, to answer these questions also requires a study of ethics.  In fact, given the extreme financial requirements for the mission plan and its continuation every two years, our guests were asked what would happen and who would pay to keep the Martian settlers alive if Mars One defaulted and could not come up with the needed funds to sustain the mission.  While our guests were familiar with this issue, it was not part of their study.  Nobody knows if governments would come to the rescue or if the Martian settlers would be left to their own survival efforts.  The MIT team said these types of ethical issues would need resolution for any Mars settlement mission. They also questioned if it would be sufficient to just sign informed consent documents that included their knowing there would be no rescue attempts for any reason.  They suggested the UN as the forum that might undertake this type of analysis and policy.  As the show was ending, our team was asked about animal food stocks brought from Earth.  Each of our guests offered us closing comments which you will want to hear.

We welcomed best selling author Andy Weir to the program to discuss his book “The Martian.”  For more information, visit his websites, http://www.andyweirauthor.com and http://www.galactanet.com.   During the first segment of our 100 minute show, Andy started out by telling us how he came up with the story idea, & his three years spent in writing the book.  I asked if he used consultants, NASA, or other aerospace experts.  He said no & that most of the feedback and help came through suggestions from people who read the chapters he put up on his website.  Andy also did his own research, math work, physics, and engineering analysis.  He talked about a few errors that were pointed out to him & indicated that the most challenging work were the times and orbits regarding Mars and the missions described in the book. During the show, Andy got lots of email questions and phone calls regarding certain story lines and sections of the book.  He was also asked about life on Mars but that issue was not relevant to his story.  He did get questions about the human waste recycling carried out on Mars & why he chose Mars and not the Moon or another destination.  Sandra asked him about the private space company plans to visit and/or settle Mars given how hard it was for Andy’s character, Watney, to survive.  Andy had very interesting comments on this question including the Elon Musk Mars plans and then Mars One.  Human factors were brought up including radiation, microgravity, vision problems, and more.  Andy did address these issues in the book so listen to his reply to this line of questioning.  As the segment ended, we talked about using Phobos and Deneb for Martian navigation along with Watney’s trek to get to Pathfinder to use its parts for communication.  NASA came up several times in the segment as readers get a pretty good “view” of NASA problem solving, information, data, and PR control, plus amazing creativity.

In the second segment, we had lots of listener emails and phone calls.  Andy was asked what science fiction had influenced him, then he got an interesting email from Andrew in Tucson who had actually worked on the Pathfinder hardware.  Andrew said Andy was spot on accurate!  Dr. Doug called on many topics including using the Hohmann Transfer Orbit which Andy did not use as he designed Hermes, the big spaceship, to work with constant acceleration using ion propulsion.  The Aldrin Cycler was also mentioned.  Listeners mentioned the new movie Interstellar and made some comparisons if they had read “The Martian” and seen the move.  In both segments, we talked about “The Martian” being made into a film for release in a year.  Andy said so far the scriptfollowed the book but he did say he has no editorial input to the movie.  We got a call from Curt in Taiwan who wished there was a PG version of the book given he wants his kids to read it and some of the language is course.  Sara emailed us from Denver asking if Andy had considered making the hero character Watney a woman instead of a man.  Tim was the last caller & he wanted to know if the hard science & engineering would be in the movie.  During this final segment, Andy was asked about how he got to Mars without a transfer orbit.  He suggested we view his animated video on this at http://www.galactanet.com/martian/hermes.mp4.  In addition, he referred us to his Google talk.  You can easily find it by searching for “Andy Weir Google Talk.”

We welcomed Mark Whittington back to the program for a wide ranging discussion on space news, policy, & technical matters.  You can follow Mark on his blog, http://curmudgeons.blogspot.com.  During the first segment of our 1 hour 46 minute program, Mark focused on the SpaceShipTwo accident, the Orbital Antares loss, the Mid-Term elections and what that may mean for space policy, Texas and the commercial space industry including the planned SpaceX spaceport, plus the space interest level of Texas Republicans taking over in the Senate and continuing in the House.  He also spoke the NASA Asteroid Redirect Mission (ARM) as a possible program to be cancelled referencing the work by Dr. Binzel at MIT who wants it cancelled in favor of finishing the NEO survey.  Later in the segment, Mark mentioned the Falcon Heavy to Mars, Inspiration Mars, and SLS.  He also talked about possible renewed interest in some sort of return to the Moon program.

In segment two, Dr. Doug called to talk about a Lunar Cots like program & a reusable lunar lander.  We addressed Dr. Dava Newman of MIT being nominated for the position of NASA Deputy Administrator.  Dava was a January 2014 guest on The Space Show and as you will hear, I think this was an excellent choice for the position.  We spoke more about SLS, then Mark mentioned the recent Whitehouse.gov call for feedback  on lunar & space policy by Tom Kalil, the Deputy Director for Policy for The White House Office of Science & Technology.  Dr. Doug and Mark talked about the ULA-Masten Zeus lander.  Mark updated us on the Lunar XPrize , we spoke about the book “The Martian” and concluded by talking about upcoming Sci-Fi TV channel space related programming .  As the program was concluding, Mark said space tourism will survive the Virgin accident but Virgin’s survival will come down to investors and customers.  He also suggested their might be congressional hearings which he thought would be fine providing they did not go to the extreme to strangle the industry with regulations & oversight.
