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 Chris Newman to the show to discuss British space policy, programs, their space industry and British space law.  During the first segment of our 88 minute program, Dr. Newman talked about space law and the space industry within the UK.  At times we compared British space law with that in the U.S., talked about the British interest in commercial space, space entrepreneurism and British government space as opposed to commercial space within the country.  As you will hear, British space is more about business and returns than government policy.  We also talked about social media and its value with some criticisms and supportive comments from me.  Mike Listner called and we did some comparisons with the British space law perspectives compared to American space law perspectives.  A listener asked if the British were fearful or concerned about the Chinese program and if they thought we might be in a space race with China.  Chris had interesting things to say in response to this question.  Chris talked about the role of the European Space Agency (ESA), competition from SpaceX with the Arianne rockets, and the ISS.  Toward the end of our segment, Alex emailed a question about the impact of our ITAR regulations on the British space, science, and technology industry.

In the second segment, I asked Chris how British citizens influence their government for space policy and matters as compared to what we do in the States.  Chris did explain the British system to us which is quite different , including their budget process.  Later I asked if the British government and people were enthusiastic about space companies, including Skylon with Reaction Engines.  You might be surprised by his response, especially when I asked if he thought the desired Skylon funding was possible.  We also talked proposed British spaceports and the possibility of British regulations on their developing space industry.  Later, George emailed in to ask if various segments of the British government competed for funding similar to what happens with the discretionary items in our budget.  Chris explained the process in more detail but the short answer was no as their budget process is quite different from ours.  Another listener asked more questions about competition in Europe from SpaceX.  Chris had much to say about this.  Other subjects discussed included a guess as to what future space missions will look like from the British perspective, more on the threat from NEOs, the global launch rate and Arianne making unrealistic market share projections, and the militarization and weaponization of space. Near the end, we talked about commercial space balloon/airship  projects like World View.  As for 2015 for British space, Christ told us to be aware of the May elections as that may set the tone for the space debate and programs for the future.  We agreed to follow up with Chris after the election to check on this.

We welcomed back Dr. Alan Stern for a quick New Horizons mission to Pluto update, that latest Uwingu projects, and a discussion of the ESA Rosetta mission and upcoming landing on Comet 67 P. Dr. Stern spent most of the time talking about Rosetta and 67P.  One of the things he stressed was how risky landing on the comet would be as this was the first ever attempt to land on a comet.  Its an interesting discussion that puts the landing in the proper perspective.  We also talked about differences with Kuiper Belt and Ort Cloud comets, the actual Philae lander, the drilling tool, taking samples from the comet, plus some of the other instruments on board.  Alan told us the circumstances under which the backup landing site would be used rather than the primary landing site.

We welcomed back Bob Zimmerman to discuss current and hot topics happening in space at this time.  During the first segment of our 2 hour 6 minute discussion, Bob asked me about the recent Bay Area-NAPA earthquake on Sunday morning, August 24, then we switched over to space topics starting with SpaceX and the Falcon 9R test launch explosion.  Next, Bob talked about the failure of the ESA Galileo GPS launch involving the Soyuz-Arianne.  Several questions came up regarding the ESA GPS system. We also talked about other regional GPS systems.  Bob moved us to the launch failure (booster rocket) for the Air Force Hypersonic vehicle, then to the decision by Sea Launch to take a break.  Bob had much to say about the Sea Launch partnership now involving mostly Russia and the Ukraine.  Russia and the ISS came up and here Bob also had much to say, including going over the news that Russia may now be interested in extending the life of the ISS.  Bob suggested some important Russian reasons for wanting to do this, see what you think.  The Atlas RD-180 rocket engine came up for discussion as did the upcoming NASA down select for commercial crew with Dream Chaser, SpaceX, and Boeing with their CST 100.  Next up was SLS which I permitted to be discussed for a while, including a call by SLS John in Ft. Worth, then I stopped it and said that SLS was a beaten to death topic on the show and that listeners and I were sick of it.  I said no more SLS talk unless there was something new on one side or the other of the SLS issue.  At one point I even assigned SLS John a new topic to research and call in about.  Let us know with your blog comments, are you sick of SLS discussions on TSS? Do you want to keep hearing them or not?  Luis emailed in about having GPS redundancy and backup systems re the European system as an example. Bob had specific ideas about this but thought the better route would be to be able to quickly replace a lost or destroyed satellite.  As the segment neared its end, Joe asked about CST and Falcon 9/Heavy & Bob had more to say about ISS modules & Doug asked a series of questions about the benefits of extending ISS to 2028.  Don’t miss Bob’s response.

In the second segment, Joe asked about small sats taking over market share from the previous big satellites.  Bob provided an interesting short discussion on this topic.  SLS John called back about the Falcon Heavy flying and then somehow the discussion focused in on presidential candidates and their space policy in upcoming elections.  After a short non-partisan review of what Bob thought might unfold depending on which party wins in November, we moved on to Rosetta and 67 P.  Bob talked about the lander and the landing sites.  Tim called in to talk about a proposal announced for space debris tracking with Lockheed and Electro Optic Systems in Australia (see http://www.lockheedmartin.com/us/news/press-releases/2014/august/0825-ss-electro.html).  Also discussed was nuclear propulsion, the Space Fence, then we got emails about fusion energy progress.  Near the end of the program, Bob talked about Curiosity, some of the electrical issues with using the on board drill, and of course the tire problem.  As the show was about to end, Kirk emailed about the recent Chinese ASAT test and Bob suggested we look for an end of the year Dragon abort test, another Falcon 9 flight and more flight tests, and the Rosetta landing on 67 P scheduled for November.

We welcomed Michael Listner back to the program for this update regarding specific space law issues and theories.  In the first segment of the this 1 hour 48 minute program, Michael talked about the proposed Asteroid Bill in Congress and how to maybe get some limited property rights for asteroid mining by being able to move a small asteroid as in the NASA ARM project.  Michael theorized that if one moves an asteroid, its no longer in its natural orbit and then no longer defined as a celestial body.  We spent most of the first segment and a good part of the second segment discussing this theory and why it might work.  When asked if it would apply to lunar property rights or other space property rights, Michael was clear that it only applied to a small asteroid that could be moved.  He also said it would require an administration to endorse such a plan and that it would be difficult to establish as customary and it would certainly be an uphill effort.  BJohn and others sent in email comments about this.  As you will hear from BJohn’s emails which I read on air, not every thought positively about Michael’s idea.  Michael also talked about other forms of international agreements being much easier to obtain than treaties.  He also said the property rights policy battles would be fought diplomatically.

In the second segment, we talked about the SpaceX-US Air Force litigation and the AF Motion to Dismiss.  Next, we covered the RD-180 rocket motor issue and Michael noted that a new shipment of RD-180 motors had been received.  He also said there was new information suggesting Russia might want to expand the mission time for the ISS (http://www.parabolicarc.com/2014/08/25/russia-agree-iss-extension).  Property rights and moving an asteroid came back as a topic in this segment & Michael again talked about treaties which he said were top down in policy making while transparency, etc. was considered bottom up policy making.  We talked quite a bit about property rights being US one sided and he said that the Asteroid Bill actually enabled those outside the U.S. to put their projects under U.S. law for U.S protection.  We moved on to cubesats and oversight/regulation issues.  Near the end, Michael updated us on the Code of Conduct in which there should be another draft emerging in the near future.  As the program was drawing to a close, I asked Michael for remaining 2014 legal issues that might get a 2014 resolve.  We looked forward to early next year & our guest commented on issues involving Russia, China, and ESA.

Please post your comments on TSS blog above.  You can reach Michael through me or using the email address he gave out on air as the program was ending.

We welcomed Mark Fisher, VP, General Manager & Director of Huntsville Operations for Schafer Corporation (www.schafercorp.com.  During the first segment of our 1 hour 25 minute discussion, Mark Fisher introduced us to the Schafer Corporation which has in excess of 40 years experience and activity in the civil, commercial, DOD, & the government space industry.  We honed in on civil and commercial and Mark talked about Bigelow Aerospace, Stratolaunch, the entrepreneurial community, and NewSpace.  This discussion took us to new technologies and here Mark said that NewSpace was providing lots of new technology.  We also talked about human spaceflight and its growth, particularly on the NewSpace side of things.  Listener Jack emailed in a question about the wisdom of international partnerships to which Mark had much to say.  I asked our guest about overlapping areas with DOD & commercial space, then about pursuing ROIs from space activities & projects & if that was a big switch from just a decade ago.  That brought up a discussion about business models and the role Schafer plays with clients in business as well as with engineering as Schafer is an engineering company.  One point made continuously by our guest was that space investment leads to results but its an ebb & flow over the long haul.  We talked about space technology, computer, and electronic advances, plus changes over time in materials and optics.  The subject of launch vehicles & the industry came up, especially with cubesats, SpaceX & Orbital.  Pooley called in to talk once again about small launchers & Microlaunchers.  At one point he commented that Leo, being too crowded, should be abandoned for escape orbital opportunities.  Both Mark & I had some interesting comments per what Charles was talking about.

In the second segment we talked about the U.S. capability to build new launchers & engines but we also talked about the high costs and long development & testing time in doing so.  Mark shared with us his rocket motor development experience.  We talked about Mark’s Schafer team, the development of an internship program at Schafer, and Shafer employment opportunities.  A listener asked about difference in approach to the public, civil, & commercial side of space projects & the need for commercial to fund itself.  We talked about wireless medial monitoring, miniaturization, & other space spinoff technologies.  Much was said about the biomedical push by NASA.  I asked about the once robust Huntsville space economy which has had some issues in recent years. An inquiry was made about DOD, Mars technology development, sharing tools with NASA, and if we needed to make weapons to advance technology.

Please post your comments/questions on TSS blog. If you want to contact our guest, you can do so through me.

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 Dr. Humberto Campins to discuss with John Batchelor and myself the recent discover of the dwarf planet Ceres water spout spewing 13 pounds of water per second into space.  Dr. Campins talked about the possible two sources of water for Ceres, what it means and why it is such an important discovery.  We also talked about Vesta and the Dawn Mission as well as the theory that Earth water came from the asteroids.  Ceres helps to validate that theory.  This is a fascinating discussion about asteroids, water, and finding out more about our early start and existence.

We welcomed back Sir Martin Rees to discuss his chapter in the new book Starship Century: Toward the Grandest Horizon, edited by James & Gregory Benford.  Sir Martin’s chapter, titled “To the Ends of the Universe,” looks forward through time and centuries to address human spaceflight, eventual interstellar travel, life extension & more.  In looking forward, he levies criticism on the past. We talked about several of his comments regarding our past & current space program. Dr. Rees mentioned the need for life extension though for Mars he said we could do that without life extension but we should not fool ourselves as it will prove far less comfortable than Mt. Everest or the South Pole.  We talked about finding planets & the possibilities for life, then we switched to the discovery of quasars soon to celebrate its 50th anniversary. Listeners asked our guest about his comments that the political impetus for current & future space work seems to have been lost, especially in contrast to the Apollo era.  In his response, our guest suggested we need low cost and reusable launch vehicles given how costly everything is today.  He commented that mining asteroids did not make sense other than for ISRU purposes. Before going to break, he was asked about the UK government investment in Skylon which he supported.

In the second segment, we spoke about changes in the UK space activity over the past decade.  Sir Martin made comparisons with the UK, ESA & NASA, especially regarding long term planning & our very short one year budgets.  He suggested our budget process makes us unreliable partners in many respects.  Quasars were again a discussion topic, plus Sir Martin fielded a question from a high school student wanting to know how we know the laws of physics are the same throughout the universe.  Another listener wanted to know about science fiction as a leading indicator for science.  Dr. Rees suggested some excellent books for those interested in reading specific science fiction works. James Benford, editor Starship Century called to point out the excellent reading list in the back of the book, plus he offered us important comments about the book & authors. Near the end, Sir Martin was asked to look forward 10-15 years & tell us his thoughts.  His response focused on finding even more planets around the stars, identifying more threatening NEOs, & even more attention given to life extension issues.  The last two questions asked our guest dealt with the ISS living beyond 2020 asking if that was valuable and also the recent podcast by Dr. Neil deGrasse Tyson that SpaceX would not be able to go to Mars.  Throughout the discussion, he mentioned the private sector doing things government could not, especially due to less risk averseness.

We welcomed Dr. Gilbert (Gil) Levin to the program for this 1 hour 25 minute broadcast.  For more information, please visit Dr. Levin’s website, www.gillevin.com.  We started our interview with a question from Leonard David asking “why is NASA running away from answering the life on Mars question?”  Dr. Levin said he had been asking the same question for 37 years and suggested several reasons including no organics, thus no life, religion, a conspiracy theory, and the most likely scenario in that such an announcement would delay or possibly prohibit human flights to Mars.  Dr. Levin went into more detail on each of these reasons, then later in the discussion Doug called in and suggested another reason, the fear of failure.  Dr. Levin talked about his experiments during this segment, the results so far, and the meaning.  He was asked many listener questions including one about perchlorates on Mars, liquid water, and searching for life via other Mars instruments including Curiosity.  Sandra emailed in a question about the religious paradigm he had mentioned earlier and Curt asked a series of questions including the subject of radiation. We talked about the private sector taking on more and more of the Mars searching for life missions, then Dr. Levin talked about the need for a fresh look at the Viking data by a truly objective panel.  He said all of the data was online and accessible.  John called with a series of questions/comments just before our break.

In the second segment, we talked about Complexity Analysis & the Wave Guide Theory.  Several questions came in regarding the Viking Labeled Release Experiments, then Gil was asked if initially he had anticipated the level of controversy resulting from Viking.   A listener asked about detecting DNA like molecules on Mars and Gil explained why DNA would not work.  Many other topics & issues were discussed including his patents & other research so don’t miss this interview. We also talked about using Kickstarter to fund a fresh, objective look at the Viking data.

Post your comments/questions on TSS blog per above. You can email Dr. Levin at the address he provided at the end of the program.  You can also see his Mars papers and work on his website.
