We welcomed Dr. Richard Binzel to the show to discuss asteroids, the NASA ARM, and completing the NEO survey.  During the program, Dr. Binzel referenced two items. The first, his article in Nature is at http://www.nature.com/news/human-spaceflight-find-asteroids-to-get-to-mars-1.16216.  The National Academies study he mentioned is at http://www.nap.edu/openbook.php?record_id=12842.  During the first segment of our 90 minute program, Dr. Binzel introduced us to the asteroid topic, the asteroid belt, 1 km size asteroids and he responded to my questions about Asteroid UR 116.  Our guest then addressed the NASA ARM and explained why he is not supportive of it.  He referenced his above article in Nature on the subject.  You can get this article at the above URL.  He talked about visiting asteroids in their natural orbit rather than bringing a small one back to orbit the Moon.  He had much to say that was positive about visiting an asteroid, explaining as well why such a visit is on the path to HSF to Mars.  He then explained his program for completing the NEO survey which is to find and catalog specific NEOs.  Listeners asked him many questions including if radar was a good tool for finding asteroids.  He said no because it uses a very narrow beam.  He also said that were the NEO survey completed, most of the most accessible destinations for HSF and science missions would be cataloged and would open up space.  He goes into detail on this near the end of our show.  We talked about international NEO survey and planetary defense issues.  While the U.S. remains the leader, ESA is doing more and more.  He also said that rather than spending just $20 million on asteroid detection, we should be spending $200 million annually until the survey is completed.  Joe in Houston sent in a series of questions starting in this segment and ending when the show ended.  His questions, all of which were read on air, centered around ways to bring an asteroid into orbit around the Moon.  Listen to what our guest had to say about his multiple suggestions/questions.  Professor Binzel clearly likes and welcomes fresh ideas & also insists on running the numbers and doing the trade analysis.  John called from Ft. Worth asking about the size of an asteroid that should be getting our attention.  Time lines were brought up as we need time for the best way to deflect an asteroid on an Earth collision trajectory.  Near the end of the segment, our guest talked about a NASA Grand Challenge Mission around asteroid detection and intervention methods starting first with the survey, the concepts on how best to deflect an asteroid and then about 30 years out, a contest on an ISRU test for resource extraction on an asteroid.

 

In the second segment, Doug sent in multiple questions, then after I asked our guest a few of them, he called in to talk about some of the other questions on his list.  Doug asked Dr. Binzel good questions so listen carefully to their discussion.  One thing of note was that the size of an asteroid presenting the greatest risk to Earth is 140 meters.  Joe continued emailing evolutions of his initial three questions from the first segment.  Asteroid ISRU was again discussed in this segment, so was the likelihood of a comet impact on Earth, & a privately funded mission to complete the NEO survey was also discussed. As the program was ending, Dr. Binzel spoke to the issue of the NEO survey being a game changer and opening the gateway to our future.  This is important so do listen to his comments on this issue.

We welcomed back Mark Bray to the program to discuss the role of space policy in his congressional campaign.  During the first segment of our 91 minute program, Mark explained why he was running for congress as an Independent candidate for the 5th District in Alabama.  We quickly focused in on the role of space in his congressional race.  In addition, is space a priority issue, how much of one, and in his district, how space aware are the voters.  I asked Mark about aerospace engineers and other engineers in the U.S. Congress.  I doubt you will be surprised the demographics Mark shared with us.  I also asked Mark for his committee choices should he win and how easy it might be for him to get a seat on one of the science, technology & space committees.  Mark talked about commercial space, the support for it in the Huntsville area, and public/private partnerships.  The art of compromise was discussed & our guest noted the absence of it in congress.  Mark explained the assets a engineer brings to the table in complex decision making and why that background is well suited for being in congress.  Since Mark works on SLS in his engineering job, of course he got a few questions about it.  I wanted to know if members of the public asked or commented to him one way or the other on SLS & its future.  He said SLS comments, when he got them, were more general.  Judy sent in a note about a video on his website, http://www.brayforcongress.com, which focused on the NASA culture of the 60s.  Mark said he was focusing on the new, young NASA that could take on the near impossible and do things because it was not yet a tried and proven member of the government bureaucracy. Today, NASA is the bureaucracy and because of that, it operates differently.  His comments were interesting, don’t miss them.  Bob asked Mark about the private sector creating jobs as opposed to the claims that the public sector creates the job.  Again, don’t miss his reply.  Dr. Rowe asked a question about making astronaut medical data more freely available to researchers, wanting to know if Congress could make such data more readily available.

In the second segment, Mark said he wanted to establish himself as the go to guy on space issues for congress.  Greg called in to talk about why space matters as a national issue.  Tim from Huntsville was the last caller on the program.  He brought up needed ITAR reform to which Mark said there were meaningful reforms on the table that he supports.  He then brought up spaceports and launch restrictions, then I asked our guest to rank campaign priorities including the economy, healthcare, foreign policy, Ebola, ISIS, Russia, and space.  Mark said the economy trumped all issues but listen to see where space is on this list.

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 back Rex Ridenoure to the show for this 96 minute discussion containing Ecliptic Enterprises updates, commercial space programs and business models,  plus much more. In the first segment, our guest provided us with updates for Ecliptic from the time he left the company to do consulting for private missions and then his return to the position he left.  Government sequestration happened about the same time and hurt Ecliptic as you will hear, plus it caused Rex to come back to Ecliptic. You will also hear how business has come back for Ecliptic since sequestration ended.  Rex talked about new contracts, the focus of their business and more.  He spoke about RocketCam and updated us on some of its new market potential plus features and advancements.  We talked about the emergence of cubesat companies as potential Ecliptic customers given the advancements in this field.  Rex talked about a new emerging business line for the company in the form of being an integrating contractor rather than only a subcontractor to a prime.  Export control and ITAR were discussed when I asked if RocketCam was being sold to foreign launchers.  The short answer was no but listen to what Rex had to say about export control and the hope for new rules in the near future.  Rex introduced us to the concept of experiment control on the ISS.  This pertains to experiments on board the ISS being controlled by ground personnel rather than by the ISS crew.  Doug called to ask about the purpose of the Ecliptic projects plus goals for Rex with his work.  Don’t miss the killer reply Rex gave Doug.  Other topics in this segment dealt with rad tolerant hardware as opposed to radiation hardened hardware and streaming data back to Earth on the DSN or another system.

In the second segment, Rex spent most of the time talking about commercial space and his years in service to developing commercial space including early in his career. See the career time table for Rex that I have posted on the blog.  Rex identified a few of the early commercial space projects he was involved with, then he said we had finished the first wave of reconnaissance of our solar system.  Listen to his explanation for this statement.  Rex next talked about one of the next big commercial areas for development which he said would be bringing  space resources to the Earth economic system.  Listener Paul emailed a question asking about commercial space efforts in other countries.  Following that discussion, Rex told us about attending the 10th anniversary XPrize event at Mojave which was an invitation only event.  I asked Rex if people were disappointed that ten years had gone by without commercial spaceflights.  He did say that their was an air of disappointment in the room among those attending the event.  Near the end of our show, Rex was asked about HSF to Mars.  He also talked about the early program Elon Musk wanted to do, Mars Oasis.  SLS came up for discussion, then Rex provided us with a list of take away points for our discussion.  He ended by saying that commercial launch dated back to 1963 and the trend was for more commercial launches and space projects.  He said commercial space was based on a 50 year old proven model.

We welcomed back Ken Murphy for a wide ranging discussion on multiple space topics including cislunar films, space economics & due diligence, capital acquisition, Boy Scouts & more.  In the first segment of our 1 hour 29 minute program, Ken talked about Cislunar Cinema which he also wrote for The Space Review (see http://www.thespacereview.com/article/2518/1.  We went through several of the films in his article but also others. We talked about foreign films, Hollywood focusing on special effects, and movie trends.  He suggested several films for us to find and view.  Next, we talked about the Boy Scouts Space Exploration Merit Badge (see http://thespacereview.com/article/2552/1.  Later, we talked about commercial space.  Ken pointed out there is still a serious lack of adequate capital for the emerging industry.  He mentioned the need for something like crowd source equity funding and he talked about supportive legislation such as the Jobs Act though the rules are not yet in place.  We talked about recent successes such as Skybox, Google, etc.  Our guest had interesting comments about these events.  He then told us stories where people told him NASA and HSF was being disassembled.  Listen to what he had to say about general population views.

In the second segment, we talked about the Dallas Moon Day which takes place at the Frontiers of Flight Museum at Love Field this Saturday, 10-5 PM.  He talked about STEM outreach, the kids getting space gift bags, the events, lectures, etc.  Ken got a listener question about the Google Lunar XPrize on which he had much to say.  Ken was then asked about various lunar commercial projects.  We talked due diligence for space projects including financial and market analysis plus assumption making..  This brought our guest to talk about general economic trends in the country and he said we were “still in a looting mode.”  After an interesting economic discussion, we turned our attention to the Moon Society (www.themoonsociety.org).  I asked Ken about the NRC Pathways HSF study with the goal of Mars.  Ken explained the Moon first position and said the real goal should be to explore the solar system, not just go to Mars.  Before closing, Ken told us about EML1, the Earth-Moon Lagrange 1.  For more information here, visit http://www.thespacereview.com/article/2033/1.  As we were closing, Ken had important comments to say about STEM and told us about his work on the Solar System Cinema.

We welcomed back to the show Dr. Paul Spudis to discuss the NRC Human Spaceflight Study report recently released. You can download the report for free at http://www.nap.edu/openbook.php?record_id=18801.  Please note that this program was broadcast and recorded live on Wednesday, June 18, 2014.  It is being archived on Friday, 6-20-24 as there will be no live show on Friday due to the host travel schedule.  During the first segment of our 1 hour 36 minute program, Dr. Spudis first walked us through the NRC nearly 300 page study, hitting the highlights, raising questions, talking about what was good in the report and disappointing in it.  We talked about the rational for human spaceflight, for Mars, also the Moon.  We noted the absence of economic development in the report and this gave Dr. Spudis several openings to talk about his ideas for cislunar economic development.  Listeners asked lots of email questions ranging from budget issues, to SpaceX and rocket reusability.  Paul described much of what the study suggested as a form of “Apollo to Mars.”  Near the end of this segment we talked about public/private partnerships and learned that the Pathways study was only addressing public programs.  A listener asked Dr. Spudis what he thought the impact of the study might be and sitting on a shelf somewhere seemed a plausible answer.

In the second segment, Dr. Spudis focused on the response to the report and ways to actually develop a quality space program.  He talked about the need for a space transportation system, space infrastructure, and to use an incremental approach.  Robotics were discussed, we talked about the space media, and Dr. Spudis reminded us a few times that if there is no infrastructure, there can be no institutional use and capability.  We also compared the Apollo period and JFK’s goal for the Moon compared to now.  Its an interesting discussion, especially since we no longer have many of the skill sets we had back then.  The value of the Moon and commercial space came up & we talked about promoting the value to policy makers.  In supporting his incremental approach, Paul referenced a bit of US naval history.

Please post your comments/questions on TSS blog.  Check out Paul’s blog, http://www.spudislunarresources.com.  You can contact Dr. Spudis through his blog or me.

We welcomed Alan Boyle back to the show for this 1 hour 42 minute discussion on numerous space news items & topics.  During our first segment, Alan talked about the “two year rule” which suggests space tourism & suborbital commercial flights are just two years away.  Throughout the program Alan kept suggesting that 2014 might be the end of the two year rule!   Alan gave us an overview of the spaceflight companies building vehicles.  Our next topic was the Yamato Meteorite, a Mars meteorite that may indicate past life on Mars.  He compared this to the 1996 meteorite announcement and said that some of the Yamato team members were the same as those addressing the 1996 “discovery” (www.nbcnews.com/#/science/space/tiny-blobs-tunnels-meteorite-revive-debate-over-life-mars-n38431).  In talking about Mars, I brought up the Viking experiments by Dr. Gil Levin , then a listener emailed in a question about the UK Tom Bower book on Branson, “Behind the Mask.”  Georgia followed with a question about the forthcoming NASA commercial crew down select, then I asked Alan for his view of SLS.  Alan said it definitely had a role to play.  Allison called from her car to inquire about private space stations & microgravity issues.

In the second segment, we discussed Planet Labs & their recent launch of cubesats from the ISS.  Alan also explained how the cubesats were launched from the station, plus since he had seen some of their images, we got a report on image quality.  Todd emailed in a additional question about cislunar transportation/lunar settlements.  Alan had several questions pertaining to what would actually be done in a lunar settlement.  Elon Musk & his Mars plans came up and we spent a few minutes talking about that subject.  Alan said the biggest dud story of 2013 in his opinion was Comet Ison.  John called from Ft. Worth & I queried him again on SLS but he actually wanted to discuss Mars & present day capabilities.  He then talked about the need for advanced propulsion for Mars flights.  He said he would back off his SLS support had there been plans for a second generation shuttle, depots or something that would be a real program.  He said SLS was a real program & any program was better than no program.  Alan then said he was looking forward to 2015 with New Horizons, Dawn, & SpaceShip2.  He also mentioned the ESA Rosetta mission,  then as the show was ending, he was asked about the Chinese lunar rover.  The final question from Sara was about the value & importance of human spaceflight.

We welcomed back Chris Carberry to this special one hour program to discuss the recently concluded Explore Mars Workshop, “Affording Mars” that was held in early December 2013.  Chris explained the purpose of the workshop and we talked about the conclusions and the plans to move forward and build upon the success of this program.  To learn more about this workshop, visit www.exploremars.org/wp-content/uploads/2014/01/Affording-Human-Exploration-of-Mars-1-12-14-final.pdf.  Listeners asked questions about defining affordability, advanced propulsion for Mars, the use of SLS, and if Inspiration Mars and Mars One contributed to their efforts.  You might be surprised by his answer to this last question.  At the midway point, we switched to other programs in play for Explore Mars, Inc.  Visit their website for information on the programs we discussed plus other information on this organization, www.exploremars.org.  In particular we talked about the upcoming legislative blitz in Washington, DC plus the April main conference, Humans 2 Mars Summit 2014.  While the conference will be in Washington, DC, it will be live streamed and we can all watch it wherever we are around the world.  One of my questions to Chris was how in a very short time, four years, he has built and made Explore Mars one of the most credible advocacy organizations and policy influencing organizations.  I also commented on the quality of their programming, attendees, speakers, all of it.  Chris did provide an explanation for this which I think all of us could benefit from.  Listen to how he said they communicate and work with others, even those opposed to Mars.  As I said, we could all learn from the Explore Mars playbook.  We also talked about robotic, science and human missions and how all are needed working together.  Chris also talked plausible timelines for HSF to Mars.

Welcome to this two hour one minute Open Lines discussion on what turned out to be mostly about artificial gravity.  While there were actually two breaks in this program, since the topic was the same throughout the full show, I am archiving this as a single segment summary.  We started the program by my making announcements, then reading parts of an article that recently appeared in the Turlock Journal (www.turlockjournal.com/section/26/article/23874) that talked about the green efforts by actor Leonardo DiCaprio but also pointing out his having arranged to be an early passenger onboard SpaceShip2.  The author of the article, Dennis Wyatt, then pointed out the hypocracy of Mr. DiCaprio by examining the carbon footprint of SpaceShip2 & comparing it to cars & other things, pointing out the enormous consumption and carbon footprint that will be unloaded on Earth by Mr. DiCaprio’s flight.  I read parts of the article to point out the hypocracy among those that preach to us to do as they say yet they seldom if ever walk their own talk.  I also mentioned articles in the informative menu of The Black Bear Diner Gazette from their Emeryville, CA menu, one of which was an old news article saying that NASA Administrator Thomas Paine predicted & had a goal of doing a HSF mission to Mars by 1981-82.  Some of the callers for today’s discussion did offer comments on both the DiCaprio article as well as wondering if we could have gone to and from Mars with astronauts back in 1981-82.  However, by far, the topic of the day was artificial gravity, a topic which really surprised me.  The callers and those sending emails wanted to talk about artificial gravity, their understanding of it, how to achieve it, their analysis of it, and more.  The callers talked 2 RMs, 3 RPMs, 4 RPMs, we talked about some of the comments by the life scientists on this subject on previous shows, much of which was discarded by the callers who had a focus on engineering and physics and their own perspectives.  We also talked about the difference between partial gravity & full 1 g artificial gravity.  I mentioned that many were unsure that 1 g of artificial gravity would be the same as 1 g here on Earth but that was quickly discarded by all callers and those sending in emails.  Our callers also talked about experiments that should take place using free flyers adjacent to the ISS to study some of the artificial gravity questions in preparation for long duration human spaceflight.  Because of the unexpected interest in artificial gravity, I have decided to arrange for updated programming on the subject with “experts” representing aerospace medicine, life scientists, engineers that would be designing space based centrifuges, and more.  I will be announcing these programs as they are scheduled & they will appear in the weekly newsletters.

Please post your comments/questions for this show on TSS blog above.  You can reach any of the callers to this program by sending your email through me at drspace@thespaceshow.com.

We welcomed back Dr. Roger Launius to discuss his new book, “Space Shuttle Legacy: How We Did It and What We Learned.”  During the first segment of this 1 hour 25 minute discussion, Dr. Launius provided us with the background behind this book which Dr. Launius and two other co-edited as a result of a suggestion Dr. Vigor Yang, chair of the School of Aerospace Engineering at Georgia Institute of Technology and James Craig, emeritus professor the school.  Dr. Launius took us through the book’s contents including the title, subject, and authors of the contributions to this book. Our guest talked about the time we spent in LEO, that it was frustrating to many but it did create the situation where LEO is no longer a space frontier.  We also talked about how the shuttle paved the way for development of NewSpace and the emerging commercial industry.  This pertains to the Washington Post article we discussed. See the URL for this article at the end of this summary.  Listeners asked him questions about the Constellation program, the use of shuttle derived architecture for Constellation rockets, and capsules versus winged spacecraft.  We also talked about commercial opportunities emerging in LEO.  A listener asked about the cost of the Soyuz for American astronaut rides to the ISS and that it was still cheaper than launching a shuttle.  Roger brought up other concerns regarding the use of the Soyuz for transport to the station.  John from Ft. Worth called and said he thought shuttle was a creation of compromise. Dr. Launius was then asked about SLS & Orion which took us into human spaceflight and the difficulty in identifying a compelling reason for HSF.  We talked about inspiration as a compelling reason but our guest said it did not hold up as there were other ways to inspire students and people.  We spoke about the Inspiration Mars mission and Mr. Tito’s recent congressional testimony.  We then talked about Dr. Zubrin’s plan to partner up with Russia for a manned mission to Mars.

In our second segment, we talked about the ISS, NANORACKS and its success, emerging ISS commercial opportunities.  However, the possible retirement of the station around 2020 is worrisome.  John emailed in wondering if the Chinese landed humans on the Moon if it would make a difference in our space program.  I asked our guest for a few of the Lessons Learned from the shuttle and we talked more about it having been an experimental aircraft and what that meant.  We got questions about new technology, advancing using new technology, and then more comments about capsules and winged spacecraft.  Roger was asked to speculate on what would happen with a subcortical accident with injury or death and an orbital accident causing crew injury or death.  As the show was nearing its end, we talked about space advocacy, its effectiveness, and the lack of a unified voice in the space community. Finally, I asked our guest for specific positive and negative lessons learned from the shuttle years.  Note that the WaPo article referred to in the discussion comparing old space with NewSpace is at www.washingtonpost.com/sf/national/2013/11/23/which-way-to-space.
