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 Gerald Driggers to the program to discuss his theories about Mars settlement but his science fiction book series Earth-Mars Chronicles.  You can find out more about his work and books by visiting http://earth-mars.com.  During the first segment of our 100 minute program, Mr. Driggers talked about his early interest in space exploration, his early work in the industry & then his becoming a space age dropout as he described it.  He told us why he embarked on the Earth-Mars Chronicles series.  Listeners sent him email questions asking him why Mars was so important & why it should be the choice for human settlement off the planet.  Gerald responded to these early “why” questions.  A listener asked if he would do a one way mission to Mars. You might be surprised by his answer.  Next up was Mars One given Gerald was one of the early supporters of the organization.  Gerald had much to say about Mars One and the Mars One model for humans to Mars.  He also discussed other HSF to Mars Models but their was lots of listener interest in discussing Mars One with our guest.  Later, Gerald said we would need to be at the Technical Readiness Level 7 (TR7) to go to Mars, be it the private sector or with the government.  June emailed to ask about the minimum viable size for a Martian settlement,  including genetic screening.  Evon emailed about landing large payloads on Mars & how Gerald addressed that problem in his books.  Gerald  brought up the need for humanity to be off Earth in case Earth is destroyed so I asked him if we needed to be in a hurry to develop an off Earth presence on Mars.  Our guest suggested it would be a very long time in coming as there was no forcing function for HSF to Mars, nor is fundamental research being done regarding human survival on long duration spaceflight trips.  Doug called to ask about the economic justification for settlements on Mars & to ask if the Moon was not a better and more economic choice than Mars.

In the second segment, Kirk from Trinidad phoned in to ask about the online presence for Mars One.  We also asked him about space in Trinidad and if it was a hot topic or area of interest.  More emails came in & Christine wanted to know what was next for Gerald in Earth-Mars Chronicles.  Tony wanted to know if there was a spiritual component to HSF to Mars.  Our guest responded in the context of religions.  Judith’s note  inquired if one of greatest blockades to space exploration were the entertainment options today including video games, computers, & other forms of entertainment.

John Batchelor and I welcome Dr. Oliver de Weck, Sydney Do, Koki Ho, & Andrew Owens to Hotel Mars for our regarding their paper and analysis, “An Independent Assessment Of The Technical Feasibility Of The Mars One Mission Plan.” You can download their 35 page report at  http://web.mit.edu/sydneydo/Public/Mars%20One%20Feasibility%20Analysis%20IAC14.pdf.  We welcomed the MIT authors of the paper “An Independent Assessment Of The Technical Feasibility Of The Mars One Mission Plan.”  John recorded four segments for an hour broadcast on The John Batchelor Show which is why you will hear the archived version divided into four segment with their own introduction.  In addition, we used a conference calling system to bring all but one of the authors on the program so you will hear a tone difference in this show and perhaps a soft echo type sound.  We apologize for any inconvenience this might cause you.

 

We started our 40 minute program by John asking Dr. de Weck for the origin of this paper.  Dr. de Weck took us back to beginning in 2004 providing us with an interesting leading up to the present time.  Given the number of guests on the program, John and I directed our questions to each person by name.  Some of the issues we talked about were life support for being on Mars and other issues referenced in their report & analysis “An Independent Assessment Of The Technical Feasibility Of The Mars One Mission Plan.” We also discussed the Mars One plan to grow food and the possible O2 poisoning resulting from that effort.  Since Mars One said that all the technologies were here now and on the ISS, the authors used the ISS as a source.  They discovered that many of the needed life support technologies are not available or tested for space let alone the Martian environment even if used here on Earth.  Our guests took us through many of the assumptions of the Mars One Mission as taken from their own statements and website.  The authors concluded that most if not all the technologies needed for humans to survive on Mars per their mission plan were today at a very low TRL or Technology Readiness Level.  Other issues that we talked about focused on the need for spare parts with this need rapidly growing to a point beyond Mars One capabilities.  3D printing was discussed as a replacement for spare parts  as was ISRU, the possible need for a rescue mission, Martian gravity & artificial gravity, Falcon Heavy launches and Dragon’s lined up on the Martian surface for the habitat plus other parts of the Mission Plan.

We welcomed Dr. Kim Binsted and Simon Engler to the show to discuss the Hawaiian Space Exploration Analog and Simulation (HI-SEAS) project.  During the first segment of our 90 minute show, Dr. Binsted and Simon introduced us to the HI-SEAS project, described its ideal location in Hawaii, and the physical site itself.  Simon was on the first mission which was a four month simulation.  He described the simulation, his experiences and perspectives throughout our discussion.  Kim also described her FMARS at Devon Island experiences in this segment.  We learned that for the HI-SEAS projects, the first focus was on food and the food system which they explained in detail.   Crew dynamics were discussed  plus our guests took us through the crew screening process.  Also talked about were crew issues, conflict resolution and crew leadership.   I asked about the relevance of analog research to a real Mars mission then our guests brought up the need to retire risks, especially team risks.  Mars One came up as did a listener question asking if the Mars simulation was applicable to the Moon.  Another listener asked how talking about HI-SEAS and Mars simulation went over with the non-space community and did they think humans to Mars was important.  Hawaii as a space state was discussed along with issues based on possible conflicts with sacred Hawaiian culture.   More questions came in about the food used for the simulations, the crew cooking, and resupply.

In the second segment, we talked about opportunistic research plus comparisons of HI-SEAS to Biosphere.  I inquired about their using submarines as models which they did in their basic habitat research plus Kim shared with us a prison story as a prison can also be a model for habitat simulations.  Judy asked a question about spiritual life and connections while on the habitat and the simulation.  Note how our guests responded to this question.  We talked about the crew EVA missions, spacesuits, and possible gender differences on the missions.  Doug sent in a note about crew cohesion, the possibility of a single gender crew, and issues of flirting, jealousy, etc.  Don’t miss both Kim’s and Simon’s discussion on this subject.  Simon did say he thought the relationships were like brother-sister on his simulation.  Crew medical concerns and issues came up as did the habitat systems and the crew developing their own strategies and protocols for dealing with issues.  Todd inquired about an exercise routine similar to what might be done on a Mars mission, then Doug emailed again about life support issues & recycling for the simulation.

Please post your comments/questions on TSS blog above. You can reach either of our guests through me or the HI-SEAS website, http://hi-seas.org.

We welcomed back Chris Carberry, Executive Director of ExploreMars.org and for the first time Joe Cassady to discuss current and new ExploreMars.org projects including the ExoLance Mission and the Time Capsule.  During the first segment of this 90 minute program, Chris provided us with a brief overview of ExploreMars.org, then he got into the specifics of their new project, ExoLance.  For more information about it and the crowd funding financial program, see http://www.indiegogo.com/projects/exolance.  Both Chris and Joe spent most of this segment with the details of this mission which will flyto Mars on an existing NASA or ESA Mars mission in the 2020s, dropping up to six tungsten penetrators loaded with life detection experiments to penetrate the Martian surface by up to 1-3 meters.  Our guests answered many emails as well as phone questions including specifics about the penetrators, the locations they would search, the tungsten penetrators serving as ballast on the main spaceflight missions, the impact velocity, and much more.  Chris and Joe several times referenced the work of Dr. Gil Levin for his labeled release (LR) experiments on the Viking missions, plus the work of Dr. Chris McKay at NASA Ames.  Both are key to designing the mission and scientific instrumentation for the penetrators.  I hope you find this detailed discussion as interesting as I found it.

In the second segment, we talked about other ExploreMars.org projects including the student led Time Capsule.  For more information, visit http://www.timecapsuletomars.com.  According to the website, the Time Capsule project sends to Mars digital messages from tens of millions of people from all corners of Earth in the form of text, images, audio and video clips.  This will Enable tens of millions of people from every country on Earth to upload their pictures, short movies, text messages and other digital media to the time capsule for about $1.00 for 10 mb.  Joe and Chris described the project, the student leaders behind it, and they invited all to participate.  Later in the segment, our guests talked about the next Humans2Mars conference scheduled for early May 2015.  They also talked some about this year’s conference and the many people that attended it plus the thousands of others around the world who saw it via streaming.  As you will hear, more than a thousand schools worldwide logged in to see the speakers as well.  Clearly, going to Mars gets people’s attention around the world like nothing else in the space field.  We got an email about possible ITAR issues with the crowd funding program and I asked our guests for Plan B if life was not discovered by the penetrators.  You might find their response to this question interesting, perhaps even entertaining.  Several listeners suggested some more advanced technology for the penetrators but the guys want to keep the first round very simple and affordable.  Based on the success of the first round of penetrators, they might evolve for future experiments.

Please post your comments/questions on TSS blog above.  You can reach either guest through ExploreMars.org or me.

We welcomed back Rand Simberg for a 1 hour 36 minute discussion regarding our HSF dependency on Russia, risk taking space safety, and more.  In our first segment, Rand talked about his book, “Safe Is Not An Option” (see http://www.safeisnotanoption.com), as well as his pointing out that what he said in his book about our growing dependence on Russia for our HSF is coming to pass.  This led to a discussing of the Sen. Shelby language in the proposed NASA funding appropriations bill to account for fixed costs in a similar way such costs are accounted for in the FAR.  Rand summarized his HSF safety comments by repeating one of his better known statements that many of us agree with, that is HSF is not important!  He discussed his meaning of this statement throughout today’s program.  Rand talked about HSF being worth the risk, 16 years of ISS and only now starting to do useful things, one of which he identified as an important drug project for curing MSRA.  This discussion prompted several listener emails including one from Jim asking if we were seeing the end of NASA/government HSF?  Tony asked Rand what he would favor were he the supreme space dictator of the country.  Rand suggested returning to the old NACA model.  Later, he said HSF is not a mature industry and compared to the 1920s airplane design as that is where spaceflight design is today.  He had much to say about safety as a priority and safety regulations.

In the second segment, Ben asked him about SpaceX being qualified for AF spy satellite launches.  I asked Rand about the Dragon V2 as he was present at the unveiling.  He went inside the capsule and shared his perspectives with us.  Space settlement came up and Rand received many email questions referring to it.  He was asked about SpaceX fast tracking Dragon V2 depending on what happens with the Russians.  We talked about influencing congress and Rand suggested writing to members of congress as the count is totaled by the members.  Given the overall low numbers for the space advocacy community, getting letters to congress is important.  Near the end of the segment, he was asked about Inspiration Mars and Mars One, he talked about the serious need for a gravity lab to determine the minimal gravity prescription.  Before our discussion ended, we talked about the NRC Pathways study on HSF and Mars.

Please post your comments/questions on The Space Show blog above.  You can contact Rand through his book website, Transterrestrial Musings (www.transterrestrial.com), or me.

We welcomed both Dan Freyer and Tabor MacCallum to discuss the upcoming Space Tech Expo to be held in Long Beach, CA from April 1-3, plus Tabor told us about World View near space balloon rides and their work on HSF missions to Mars.  There was only one segment for this one hour program.  We started with Dan who gave us an overview of the Space Tech Expo (www.spacetechexpo.com).  He talked about the free program, the paid program, the exhibits, and the B2B focus of the conference.  We went through the paid Expo agenda which you can find at http://www.spacetechexpo.com/conference/conference-program-2014.  Dan stressed the business 2 business focus of the expo, talked about the mix of aerospace, defense, military, satellite, launch vehicle companies and executives that will be attending. We also talked about the exhibitors and their ability to tell attendees about their products and services.  Taber jumped in to talk about the World View near space balloon rides which they will be talking about at their booth #4042.  Dan also went over the conference logistics and fielded several questions asking about NewSpace representation at the expo, the possibility for students & interviews, networking opportunities, lunches with the paid program, plus more.  Later in the segment, Tabor received several email questions about his work on the life support systems for human spaceflight missions to Mars.  He talked about going to Mars, Inspiration Mars, Mars One and a stepping stone approach that might include going to an asteroid and the moons of Mars.  We discussed the possible need to first go to the Moon to learn how to go to Mars.  We talked about closed loop systems, radiation & microgravity issues, plus the complexity of landing large payloads on Mars. We concluded our hour discussion by reviewing the Expo logistics, registration on their website, and the strong business focus for this conference.

Please post comments/questions on TSS blog above.  Questions for our guests can go through me or if you have Expo questions, use the Expo website contact information.

We welcomed back Dr. Jeff Bell & was at his best for blunt talk, specifically the need for a winning rational for human spaceflight (HSF).  For those of you new to Dr. Bell, hold on tight for a ride that will likely be upsetting.  During the first segment of our 1 hour 58 minute program, Dr. Bell started with saying he was pessimistic over the future of human spaceflight.  In fact, this was an overriding theme throughout the full discussion.  He said it was more than just not properly telling the story either by NASA or space advocates.  He said there was no winning rational for the need or the urgency of HSF.  While he was pessimistic on HSF, he was just the opposite on science, robotic, & unmanned missions which he said were doing well & in a class of their own.  He also talked about the success of satellites & that part of the commercial industry.  Listeners challenged him during the show.  He got several emails regarding space settlement which Jeff addressed in terms of his perspective on HSF.  He also nixed the idea of leaving Earth as a safety valve for when Earth might be destroyed by an incoming NEO.  This led Jeff to talk about planetary defense.  Tony called with an idea to keep a Martian settlement from freezing at night, a point Jeff talked about re Mars settlements.  A listener asked about radiation & magnetic fields.  Jeff said the atmosphere was more of a screen for Earth, again in a discussion about lunar & Martian settlements.  Jeff talked about Orion & SLS, various ideas for Mars missions & the NASA asteroid mission.  I asked Jeff what he was positive about & he replied the Russian space program & SpaceX with Elon.  He then spoke about some of the Russian programs he follows.  He was asked about space tourism & suborbital flights, then he spoke about SpaceShip2 problems, hybrid engine issues, Richard Branson & more.

In the second segment, he had more to say re SpaceShip2 & Branson.  Next, he was asked about space debris cleanup ideas being skeptical of them.  He was also skeptical of propellant depots.  He spoke about small boosters costing much more than using one large booster.  Pooley called in to support everything Jeff was talking about.  Dr. Bell was asked about Dream Chaser.  In general, Jeff was very critical of lifting bodies & their CG problems.  Listeners asked for his assessment of Inspiration Mars & Mars One which was not positive.  In his closing comments, he said HSF was probably mature & needed radical new technologies to make it cheaper & feasible.  I told him he should come back on the show, invite only callers & emails suggesting radically new & different technologies & he could assess the ideas.  Dr. Bell agreed to do that so watch the newsletter for this upcoming program.

We welcomed back Robert Walker from the UK to discuss artificial gravity with us given our recent Space Show programs on the subject.  There was an audio issue with this program so listen carefully so you don’t miss anything.  During the first segment of our 90 minute program, Robert went over some of the basics such as the Coriolis effect, the gravity gradient, tethers, centrifuges, the vestibular effect, and more.  He also went over linear acceleration, spin rates, Russian experiments, issues facing space tourists, and spinning a Dragon capsule.  Robert has written many articles on artificial gravity which can be found at www.science20.com/space.  One such article was discussed yesterday. See  www.science20.com/robert_inventor/blog/ingeious_idea_soyuz_crew_tether_spin_way_iss_artificial_gravity_almost_no_extra_fuel-131278.  Also, check out www.science20.com/print/131279; www.science20.com/print/131278 & www.science20.com/print/129424.

In our second segment, Robert talked about both Inspiration Mars and Mars One as it relates to spinning to create artificial gravity, the number of revolutions per minute, simulate programs, and his favorite, a 2-3 year precursor mission at Earth L2.  He wants the mission designed to be a comprehensive test bed for artificial gravity.  Later in the segment while discussing Mars, he suggested we orbit Mars and not land on the planet.  Listen to his reasoning for this type of human Mars mission.  For one thing, he said its much safer to be in orbit.  We then focused on the possibility of microbial life on Mars, we talked about the Viking Labeled Release experiments.  Robert was asked a question about the sleeping centrifuge (you sleep horizontal as one does on Earth).  Partial gravity was discussed as well.  Robert said many times that we must find out what is going on with Mars. He mentioned the Phoenix mission which Mars One is planning to copy to some degree with its robotic mission to Mars in 2018.
