Space Show 2000th Program & 12th Anniversary Tribute, Tuesday, 5-7-13

http://archived.thespaceshow.com/shows/2004-BWB-2013-05-07.mp3

Guests:  Dr. John Jurist and Dr. Doug Plata served as co-hosts.  Topics: This program honored The Space Show for its more than 2,000 programs and its upcoming 12th anniversary.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://thespaceshow.wordpress.com.  Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use.

This Space Show program stands out among all Space Show programs as it honors The Space Show for having passed the 2,000 program mark plus the upcoming 12th anniversary of the program later this month.  Dr. Plata and Dr. John Jurist organized this program, much of which was a surprise to me.  Dr. Plata set up a special tribute email address, honordrspace@gmail.com and they both contacted guests and listeners for their comments on the program and what they believe The Space Show has meant to them, the space world, and to our space development efforts.  Our 1 hour 47 minute program was in two segments but this summary will not be divided by segment as topics overlapped one another. Dr. Jurist asked me lots of questions about how the program started, how it has changed over the years, how the audience has changed, and how I’ve changed.  After asking one or two questions and getting my long winded responses, Dr. Plata read some great emails sent in by guests and listeners.  This was the format for the entire program.  Honestly, I was really surprised by the comments, the statements of support and meaning for The Space Show and by those of you that took time from your busy schedules to say a few words about the program.  It was a very humbling experience for me and I am glad it was an audio only program rather a webinar as I was really moved by the outpouring of support for the program and me.  Doug did not have time to read all the emails that came in but we intend to post them to the blog and will continue posting them to the blog as they come in.  Please use the special email address above but for those of you that use the regular program address, I will copy and post them to the blog as well.  John asked lots of questions about the economic impact on space, both here and around the world, about private space, NASA, human spaceflight, and such.  I spoke about public/private partnerships, the need, in my opinion, for American leadership in science and space, and why.  We also took phone calls from listeners wanting to comment on this special Space Show program.  As our program was drawing to a close, John asked me about library quality archives for research with a truly searchable, interactive academic data base.  We talked about this, what it might take to do it given the number and average length of Space Show programs.  If any of you have actual library, research and multimedia academic catalog search experience, we would like to hear from you to find out about creating a truly researchable, academic Space Show catalog/library.  If you have that type of specialized experience, please contact me using drspace@thespaceshow.com.  Perhaps we will create a funding mechanism to create the library for our archived programs and new programs coming up.

We welcome your comments/questions and more so post them on The Space Show blog.  I look forward to many more years with The Space Show, to continuing to provide a civil and credible forum for the discussion of all perspectives and points of view, and to give a voice to many of you that have much to say but are without a microphone. This program was number 2,004 and as I said on the air, the program would not exist without you the listeners and with you the guests who so freely give of your time to help us all learn more about space, science, and all that we talk about and share on The Space Show.  Thank you very much and as I said on the show and as many of you said as well, the next 2,000 shows will be even more valuable to us all than the first 2,000!  The Space Show only exists because of you the listeners and you the guests.  I never lose sight of that.  I never will.

We welcomed Dr. William (Bill) Farrand to the program to discuss Martian multispectral & hyperspectral remote sensing data, the same for the Earth and throughout our solar system.  To find out more about Dr. Farrand and his work, please visit his website at http://farrviewconsulting.com.  In the first segment of our 90 minute discussion, we talked about the Mars solar conjunction, what the rover Opportunity is doing during the conjunction, Opportunity’s longevity, and why Spirit quit working.  We also talked about Curiosity, then I asked our guest about both multispectral and hyperspectral remote sensing data for Mars.  Dr. Farrand explained the imaging and the instruments in addition what we learn about Mars and other solar system objects through the remote sensing instruments providing us with this data.  In fact, in response to a listener email, our guest talked about remote sensing data from the Messenger, Cassini, Dawn, and other missions.  I asked our guest about minerals on Mars and throughout the solar system and how they might differ from the same mineral here on Earth.  Doug sent in a question about trades with the science missions as compared to doing a human spaceflight mission.  Our guest expanded the discussion to include very expensive science missions as opposed to more missions but lower in cost.  Dr. Farrand talked about the proposed commercial space missions to the Moon, Mars, and for resource utilization.  He also talked about the prize system as being a good way to further commercial exploration and development.  A listener asked about getting timely data released to the public.  Our guest directed us to the Planetary Data System which houses all the mission data, usually about six months after it was first obtained. 

In our second segment, Doug asked that if Curiosity comes up empty, might that seriously put life on Mars into doubt?  Don’t miss the response, it might surprise you.  We then discussed Curiosity and what it was up to at this time plus more on Opportunity.  As for future Mars missions, we talked about Maven and then our guest was asked if the current Mars science and robotic missions were designed to pave the way for an eventual human spaceflight mission to Mars.  He said they were not so tightly linked but it’s a discussion you will want to hear.  Our questions then changed to NASA economics and sequestration as our guest was asked for his thoughts on cutbacks, sequestration, moral, etc.  I asked about Earth remote sensing and we talked about Landsat satellites and Landsat 8.  Also the commercial World View 2 and the coming World View 3.  We talked about buying commercial data as opposed to using government sourced data, plus AI, real time data acquisition and more.  Near the end, Karen asked about the role the scientist plays in designing & developing the satellites & tools on board it. 

Please post your comments and questions on The Space Show blog above.  You can email our guest through his website or me using drspace@thespaceshow.com.

Robert Sackheim, Monday, 4-1-13

http://archived.thespaceshow.com/shows/1986-BWB-2013-04-01.mp3

Guest:  Robert (Bob) Sackheim.  Topics:  Commercial space, propulsion, U.S. space policy & more. Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://thespaceshow.wordpress.com.  Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information.

We welcomed Robert Sackheim to the program to discuss NASA, commercial space, the current state of rocket propulsion and advancements in the field.  During our first segment of this 1 hour 47 minute discussion, Mr. Sackheim talked about his background and experience at TRW, NASA MSFC, and his current consulting.  I asked him several questions about the current state of rocket propulsion. Bob had much to say about this, focusing on chemical rocket propulsion, satellite propulsion, electric propulsion, and the need for nuclear propulsion.  He talked about booster rockets, various rocket stages and their propulsion, rocket engines, and even SRBs.  Several questions came in asking him if we had the current technology for HSF to Mars or even the Inspiration Mars flyby mission talked about so much in the recent press.  Listeners wanted to know if our current levels of propulsion were up to the task.  After a rather thorough propulsion discussions, Bob turned to commercial space, lowering total space mission costs, regulatory policy, and commercial spaceports.  He also talked about budget issues and raised the question a few times as to why ten NASA centers were needed given their often overlapping, competitive, and duplicate work.

In our second segment, commercial space took the lead with a discussion on public/private partnerships & the belief that Americans can do anything if we set our mind to it, including space travel.  Of course here the problem as we know lies in leadership and today it appears that leadership in space & other areas is sparse at best.   Bob then focused on geo satellites and the increasing development and capabilities applicable to cubesats.  HSF came up for discussion as did the robotic missions. You might be surprised by what our guest had to say about HSF.  Other issues in this segment included the lunar space elevator, the congressional and NASA track record in canceling ongoing projects & taking lessons from history, SSP, & ways to reform & move NASA forward.  Bob spoke about evolving toward the old NACA model.  I asked about the impact of space advocacy from his perspective given his leadership experience and past positions in leading organizations and projects.  We also asked him about space tourism and hybrid rocket engines. He had much to say about hybrids, don’t miss the discussion.  Bob talked about the Falcon rockets, testing including static fire tests, and SRBs as related to the Constellation project and safety.  Toward the end, our guest was asked about NewSpace, fuel depots, & cryo transfer.  For closing comments, he talked about commercial space being the way to go & the path to our space future.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information.

We welcomed Dr. Claude Piantadosi to the program to discuss his new book, “Mankind Beyond Earth: The History, Science, and Future of Human Space Exploration.”  If you buy the book using this Amazon URL, www.amazon.com/Claude-A.-Piantadosi/e/B001IU0QRS/ref=onegiantlea20, Amazon will contribute to The Space Show/OGLF.  During our first segment of this two hour discussion, we compared the space environment to the undersea environment, and live support and environmental issues with a nuclear submarine as opposed to what we have available today for space flight.  Our guest talked about the advantages of human spaceflight (HSF) over robotic missions, plus the contributions to advancing technology, science & our understanding of our own environment derived from HSF.  Radiation & microgravity issues were mentioned and listeners started asking detailed questions pertaining HSF and Mars missions.  Much of this segment focused the two planned Mars missions and the human factors challenges.  In addition to a comprehensive analysis from the medical perspective, listeners also pointed out that Inspire Mars would likely have indirect if not direct public money supporting the mission.  Most were less supportive of the mission if it included public money, direct or indirect.  Dr. Piantadosi talked about radiation & microgravity unknowns and variables. He also talked about our current time line for meeting human factors & life support challenges over the near term which was not good.

In our second segment, we talked about affordable space & how to achieve it. Heavy lift and SLS came up as did fuel depots and reusability.  A listener asked about older people being more radiation resistant or tolerant. Long duration spaceflight mental issues came up and our guest talked about them in the context of crew selection and training.  Procreation in space was discussed as was the mass needed for water radiation shielding.  Our guest suggested that since the shuttle retirement, our space program had lost its focus.  He said there were no plans to get us the next level of information needed for travel beyond the Van Allen Belts.  He also talked about a lunar first program to learn and get the needed information to go to an asteroid or Mars, suggesting this might be a 15-20 year research program.  In the context of lengthy missions, our guest addressed sequestration and the need for international projects and financing. When asked if the recently announced private deep space missions had an edge over public mission, he did not think so.  Don’t miss what our guest said about this.  In closing, he urged us to engage in critical reading and critical thinking about problems.  Space is essential & we need to move forward with it using a good development & exploration plan.

Please post your comments/questions for Dr. Piantadosi on The Space Show blog above.  You can reach our guest through me at drspace@thespaceshow.com.

Dr. Neil deGrasse Tyson, Friday, 3-8-13

http://archived.thespaceshow.com/shows/1968-BWB-2013-03-08.mp3

Guest:  Dr. Neil deGrasse Tyson.  Topics:  Dr. Tyson’s book, “Space Chronicles: Facing The Ultimate Frontier,” delusional thinking, space exploration, space economic power.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://thespaceshow.wordpress.com.  Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information.

We welcomed backed Dr. Neil deGrasse Tyson to this 60 minute discussion about the new release of the paperback version of his current book, “Space Chronicles: Facing The Ultimate Frontier.”  If you buy the book with this Amazon link, Amazon will make a contribution to The Space Show/OGLF:  http://www.amazon.com/Space-Chronicles-Facing-Ultimate-Frontier/dp/0393343626/ref=onegiantlea20.  The book is a collection of all of Dr. Tyson’s thoughts about the past, present, and future in space.  It consists of essays, tweets, op-eds and more, plus an appendix with important documents such as the original agreement creating NASA in the late 1950s.  Neil said that some of the points he made in the book were that space was expensive and that we do things in space for one of two reasons: 1.  As a result of military threat or war; 2: In support of economic growth of the country.  He then supported his argument with historical facts, making the point that we do not explore for the sake of exploring, that exploration is not in our DNA, that we do not go into space to inspire future generations of kids, and then he even mentioned that the famous JFK Rice University speech which he said was a lie in that weeks before in a speech before Congress, President Kennedy put forth the real reason we were going to the Moon which was to show the world a path of freedom over tyranny.  Dr. Tyson documents this on p. 192 of his book by saying that “Kennedy did adopt a military posture in his speech to Congress.”  Neil stressed this point during our discussion in support of the above reasons for developing.  More about this speech can be found at www.history.com/this-day-in-history/jfk-asks-congress-to-support-the-space-program.  The actual text of the speech can be seen at www.jfklibrary.org/Asset-Viewer/xzw1gaeeTES6khED14P1Iw.aspx.  Dr. Tyson also talked about the problem of delusional thinking among space enthusiasts, a theme we went back to several times during our discussion.  Another point he made was about the importance of innovation and having a culture of innovation with space goals supporting the economic growth of an innovative nation.  Kelly asked a question about the best way to increase NASAs budget in bipartisan support of space for STEM, inspiration, spin-offs, etc.  Our guest said all of the reasons cited in Kelly’s question were irrelevant.  Don’t miss what he said.  We also talked about the need for infrastructure and Neil said that governments have to pave the way for the frontier and the private companies follow and economically develop it.  He said the commercial companies do not and will not be able to open the space frontier with the needed infrastructure.  I then depicted government as sort of an advance man in space with the privates being able to capitalize that infrastructure development for profit & national wealth. A listener asked about China, a space race, and a possible space war.  Dr. Tyson also said that we should have launch vehicles that go everywhere for research and innovative reasons and we needed to shift our culture to seeing space as a long term national investment for creating wealth for the nation, far beyond the term of our elected officials.  He talked about SpaceX and the need for a rich and fertile collaboration between government and the commercial companies regarding space.  I asked our guest about testifying before Congress. You will want to hear what he had to say about that based on his experiences in do so.  We talked about space and grass roots movements. He talked about GDP economic growth during the Apollo period and then what happened each decade after that through the current period.  Jim sent in a question pointing out possible contradictions in his comments & suggested fuel depots as a way to minimize the quantity of rockets and launches. Dr Tyson said he was hardware agnostic and that in developing infrastructure and paving the way for the privates in space, fuel depots might very well be part of infrastructure but that government would be doing them, especially early on.  Later, Dr. Tyson talked about our system being a political system and that it was not going to change.  He used this as one of the examples of delusional thinking given many enthusiasts who don’t accept this reality & believe they can bypass or work around the political nature of our government and systems.  Near the end of our discussion, he was asked about the Inspire Mars mission which he said was probably a stunt but that it might serve the purpose of showing the government that lots of people are interested in an HSF to Mars.  Another listener wanted to know if the Inspire Mars mission turned out bad, would it derail human spaceflight.  He did not think it would do that given other space accidents with the loss of crew.

Please post your comments/questions on The Space Show blog and I will call them to the attention of our guest.

Dr. Henry Hertzfeld, Tuesday, 3-5-13

http://archived.thespaceshow.com/shows/1964-BWB-2013-03-05.mp3

Guest:  Dr. Henry Hertzfeld.  Topics:  Commercial space, Mars, human spaceflight, regulations & economics.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://thespaceshow.wordpress.com.  Comments and questions should be relevant to the specific Space Show program.

We welcomed Dr. Henry Hertzfeld back to the show for a fascinating 90 minute discussion regarding commercial space, human spaceflight (HSF), recently announced HSF Mars missions, increasing the launch rate, and more.  During our initial segment, Dr. Hertzfeld addressed my question about lowering launch prices to increase the launch rate.  Dr. Hertzfeld did a classic economic study on this subject several years ago and I asked him if today’s current market and commercial space progress had altered his earlier conclusions.  He said no. Later, I asked if space solar power (SSP) could drive launch rates down.  The short answer was no but don’t miss what he had to say about SSP economics, launches, and debris issues.  Jerry emailed in a question about SpaceX being a commercial company given its receipt of government money.  Henry had much to say about what makes a company commercial or not and if it is even an important issue.  Another listener wanted to know about the deep space commercial ventures announced in 2012 and in 2013.  The listener wanted to know if these were really commercial ventures, if regulations could stop them, and what would happen re the ventures needing property rights or the equivalent.  One of the things our guest reiterated several times during our discussion was the need for stability and predictability for the commercial industry.  Questions came in about benefit sharing and he mentioned the likelihood that some sort of international system would develop on these issues. I asked what constituted an acceptable ROI and the example of controlled ROIs as in the utility industry came up.  Doug wanted to know about rocket reusability and its impact on launch costs.  We also talked about both Mars One and the new Inspiration Mars mission.  As part of this discussion, astronaut rescue and the rescue treaty were discussed.  In the second segment, Doug called to discuss property rights for a NEO as opposed to the Moon, wondering if the Moon might be more valuable.  Doug & Henry talked about our having returned lunar rockets as a model for commercially returning lunar products but Henry suggested there might be a difference in returning something for science as compared to commercial exploitation.  Later, we addressed human spaceflight and its challenges.  The Chinese space program was brought up as was the risk of a space war.  Dr. Hertzfeld was asked about putting 10,000 people on Mars, space migration, species survival, space settlement, and the need to explore as possible drivers for HSF.  My final question pertained to our evolving to a business friendly environment in space.  Simply put, we are not there yet.

We welcomed back Dr. John Lewis to discuss recent meteorite impacts, NEO flybys, asteroid minding, the Chinese space program and more.  In the first segment of our 90 minute program, Dr. Lewis talked briefly about accepting the position of Chief Scientist for the new company, Deep Space Industries.  He also spoke in general terms about this emerging industry.  Our initial caller asked Dr. Lewis about his writing science fiction so you will hear about that as well.  We then turned our attention to the Chelyabinsk meteorite and the flyby of Asteroid 2012 DA14.  Visit www.johnslewis.com for detailed information on these events plus much more.  The Russian meteorite  was estimated to be about 10,000 tons or the mass of a U.S. Navy cruiser.  Dr. Lewis explained why it was not detected before hitting the atmosphere.  We then speculated on what would have happened had it come in over a large city such as London.  Dr. Lurio called in to talk about his joining Deep Space Industries as the Chief Scientist.  Charles also wanted to know about the previous announcements that he would be an advisor for Planetary Resources.  Dr. Lewis explained this and corrected misunderstandings regarding the issues addressed by the question.  Jack sent in an email seeking mining comparisons here on Earth to those in space given his being in mining country in Virginia.  Another listener asked about the potential dollar value of the Chelyabinsk meteorite.  In his response, John suggested the best value for using asteroids in space re ISRU.  Another question came up about hollowing out an asteroid and using it for HSF travel.  Dr. Lewis talked about this idea dating back to 1918 and Robert Goddard.  Kelly asked about moving an asteroid to a low lunar orbit and if a human mission to a NEO was a good stepping stone for a human flight to Mars. John had much to say to us on both of Kelly’s questions.

In the second segment, we opened with my asking John about the Chinese space program and their high launch rate.  Don’t miss John’s comprehensive answer about both the Chinese military space program and their quasi-civil space program.  It was most informative.  Next, John told us about an incident when he was 13 years old living in a Boston suburb with what was probably a meteorite coming in overhead that disturbed his entire neighborhood.  It’s a fascinating story that illustrates events like we just saw in Russia are fairly common throughout history.  Don’t miss this story!  Another topic in this segment was the low quality science and news reporting in this country. Dr. Lewis expressed concern about this with some explanations to help us understand the reality of today’s news reporting services.  Listener Bruce sent in an email asking about nuclear explosions to deflect a larger asteroid and doing such tests in space.  Again, Dr. Lewis had much to say and offer us on this issue.  This led to a discussion on detecting Earth-bound NEOs, what sizes we can and cannot detect today, the amount of warning time we might have and more.  Near the end of our discussion, Emma in NYC sent in a note asking John what the Chelyabinsk meteorite  would have looked like had it come in over a Martian settlement.  John’s response was fascinating and very descriptive.  Pooley sent in an email with the classic NASA NEO website, http://neo.jpl.nasa.gov/ca.
