We welcomed Dr. David Crisp to the show to discuss the NASA Orbiting Carbon Observatory-2(OCO-2) satellite. During the first segment of our 94 minute program, Dr. Crisp started out by presenting a short overview of the OCO satellites, the first two of which did not make it to orbit due to fairing failure after their Vandenberg launch. For the third attempt, NASA switched rockets to the Delta 2 and the satellite made it to orbit without a problem. Dr. Crisp then explained how OCO-2 works, how it detects and measures CO2 in the atmosphere from the ground up. He explained the color intensity and why the information is so accurate. I asked him to compare OCO-2 data with climate models. Here, Dr. Crisp stressed the fact that he was not a climate scientist or policy maker. That said, he did compare and contrast OCO-2 data with climate models to the degree reasonable comparisons can be made. We talked about natural sources of CO2 on earth, both land and water (ocean, rivers, and lakes), as compared to manmade sources of CO2. Dr. Crisp explained the emitting and absorption capabilities from the natural CO2 sources, photosynthesis with plants, and the fact that manmade CO2 is only emitted, not absorbed. This CO2 can stay in the atmosphere for a thousand years or so. He talked about the total parts per million of CO2 in the atmosphere, how it has gone down and now is going up over the years and the amount of human created CO2 in the atmosphere and how that has increased over the years. Listeners asked about methane but OCO-2 was not designed to detect methane. He was also asked about water vapor. Dr. Crisp explained that water vapor in the atmosphere was detected and measured by other satellites, particularly weather satellites so it was not part of this genre of satellites. Jack emailed in a question to point out that a pause was going on for the past 19 years or so and the planet was not cooling despite human CO2 increases. Dr. Crisp offered an explanation for the pause so don’t miss it.   Jane from Seattle brought up the fact that warming and cooling on Earth has been going on since the beginning of time, without human produced C02. She asked how this could be given the conclusions many make regarding the increase in human produced CO2 levels for today causing global warming. Don’t miss how Dr. Crisp responded to Jane. Dr. Crisp also talked about solar warming and cooling cycles and said we are currently in a solar cooling cycle. Randy emailed in a question about the draught in California and its relationship to CO2 increases.

In the second segment, Becky in Las Vegas sent in a note asking about the climate and atmosphere on Venus and Mars given our guest has studied both planets. She was looking for a common link with Earth or maybe a common trend. Dr. Crisp had much to say about both Venus and Mars. Later in the discussion, I asked if humans were on Venus with advanced technology, could they have intervened in the global warming process and mitigated the impact of it. He said he doubted it, explained why and then the same question was asked about Mars though the situation on Mars was and is different than on Venus. For the most part, Venus was too close to the sun to do anything about it and Mars was too far to do anything about the Martian problems. This is why Earth is in the Goldilocks zone and why we search for exoplanets in this zone. Later, Dr. Crisp talked about today having the highest CO2 levels ever and the growing Earth population which is around 7.2 billion people having nearly doubled over the last 45-50 years. This led us to a discussion about energy, including coal, natural gas & nuclear power. He had some surprising comments about China and coal, don’t miss them. We also talked about India and its use of coal, then Dr. Crisp talk about the need to be able to store power, use solar and wind power, and to enlarge the grid to take wind or solar from areas where it was strong to be able to ship to areas that needed it. He also talked about the need to improve energy storage. Near the end of the program, I asked about any surprises discovered from the OCO-2 data. We then talked about how long OCO-2 would last and here, we talked about the design as a demo satellite without redundant or backup systems. A listener asked if cubesats could do such an OCO-2 type mission. Don’t miss his answer but the simple one was no because the technology for doing this requires hardware that is considerably larger than could be used by a cubesat. Before the show ended, we talked about the NASA Earth Science Budget, the cost per taxpayer, and our ability to freely download OCO-2 data off their website. He then identified the largest user and downloader of the data. I bet you will be surprised by what he said. NASA was the second largest downloader of the data.

We welcomed Dr. Judith Curry to the show to discuss climate science as Dr. Curry is a noted climate scientist from Georgia Institute of Technology. Follow Dr. Curry on her exceptional blog, Climate Etc. @ http://judithcurry.com. Her faculty page website at Georgia Tech is http://curry.eas.gatech.edu .

In the first few minutes of our 55 minute discussion with Dr. Curry, I asked her for a brief history & time line of when the issue of climate science got the attention of the public and started to be highly politicized. Dr. Curry traced it back to the late 90s and then the 2001 UN Assessment. I asked her about the partisanship, the public being confused, and more and she said these were normal states to be in regarding climate science which she said several times during the show was a “wicked mess.” Dr. Curry then gave us a brief history of warming trends going back hundreds of years, their possible causes and then she talked about the complexity of climate data and how hard it was to correlate, make assumptions with, and to draw useful conclusions for sound policy making. We talked about multiple sources of data collection from space resources to climate models. Regarding climate models, she said they run hot, everyone knows it, but it is very hard to fix the problem and then she explained why. Listeners asked about bias in the data, news reports, even with other scientists. Bias and the use of proxies to spread this or that perspective on climate science was all too common and is a problem. Another of Dr. Curry’s points was that given the problems with climate data, there are “deep uncertainties” regarding the state of climate science but that does not mean the risks should be ignored. The balancing act is to understand the data as objectively as possible to manage the risks in the best way possible. When asked by listeners about regulations, she said that a better way to mitigate possible climate problems was through the use of technology and innovation. Don’t miss her comments about this, especially as she applied them to the energy business. She also brought up the risk of serious unintended consequences to whatever we do, whatever policies we put in place, again because there is so much uncertainty with the data and the subject is very complex and not lending itself to simple solutions. Dr. Doug called the show to ask about solar cycles. Doug kept asking the question though our guest did respond. Specifically, I believe Doug was asking her how solar cycle length correlates with global surface temperatures. Listen to the exchange and see what you think about this mini-discussion. Later Doug sent me a graphical image related to his series of questions but our discussion had moved on plus I had no way of getting the graph to Dr. Curry for discussion. Listeners asked Dr. Curry about emissions, CO2, regulatory mandates and policy. Another question for Dr. Curry focused on scientific consensus regarding climate change issues. Don’t miss this discussion. BJohn asked about planetary science & solar system climate studies. Later, she was asked about testifying before Congress. Dr. Curry said there was a difference between testifying in the House as compared to the Senate. I asked if she had ever given a presentation to the UN or elsewhere. In response, she talked about her recent experience speaking before Parliament in the UK to the House of Commons. Compare what she said about the UK experience to her congressional experience. Near the end of our discussion, Dr. Curry spoke about her climate change and science blog, Climate Etc. per the above URL. If you are interested in these subjects, following her blog would be highly beneficial. Before the program ended, I asked if her graduate students came to the classes with a bias or if they were open minded in their climate science studies. I then asked if climate science in the U.S. was dependent on who the president was and what party was in power. Dr. Curry had very interesting comments on this plus she gave us the recent history of what happened to the field over the past several administrations, both Democratic and Republican. Finally, I asked how important it might be for the general public to have a good, bias free understanding of climate issues. Her response might surprise you so make sure you hear what she had to say about this and science education in general. A last minute question was asked about the famous hockey stick graph, then our guest provided us with good, solid closing comments.

We welcomed Jim Muncy back to the program to discuss current space policy and budget issues before the U.S. Congress, company updates, and much more.  During the first segment of our 1 hour 50 minute discussion, Jim provided us with the groundwork for most of our discussion by going back to the Commercial Space Launch Act of 1984, then the update to it known as the Commercial Space Launch Amendments Act of 2004.  He talked about both the House and Senate versions of the NASA and space budget bills and some of the differences between the two bills.  One difference which he explained in detail early in the second segment had to do with the learning period which is important for the developing industry.  Another difference between the two revolved around extending the ISS commitment to 2024 plus issues relating to BLEO space.  When asked if he thought the final bill would be signed or vetoed by the president, he said it was nonpartisan and he did not see problems getting it signed into law.  Listeners asked about funding SLS.  Much was said about SLS in both segments but one listener asked Jim why so many supported SLS given its shortcomings.  Jim explained the mindset of many SLS supporters in congress. As you will hear, SLS is hardly a black or white issue.  This discussion led to a related discussion on developing a new rocket engine, the issues involved, the competitors, methane versus other fuel, and more.  In particular, he used Alabama Congressman Mike Rogers as an example supporting is analysis of the situation.  Jim was asked about the impact of the Falcon 9 failure which led him to address the need for multiple launchers and competition.  Later, Alex asked him about his areas of concern regarding the pending budget legislation.  He talked about sequestration, spending caps, delays, and the problem with operating on a CR which is likely.  This is a lengthy but important discussion so don’t miss it.  Before the segment ended, Jim was asked about the lunar lander.  Jim then talked about the Flexible Path, Google Lunar XPrize, cislunar space development and Mars.  Jim advocated the need for public private partnerships, then he was asked about international partnerships.

 

In the second segment, we started with an email question from Doug inquiring about the Augustine Commission presenting an option for returning to the Moon with landers developed in a public-private program context.  After Jim’s response, I asked him to refer back to a comment he made in the first segment and to explain what was meant by the learning period.  This was an important discussion so don’t miss it.  As part of his response, he also provided a short overview of the suborbital industry and participants plus the orbital industry.  A good portion of this segment focused on the importance of the learning period.  Our last question of the evening was from Helen.  She asked Jim if it would be beneficial to ask political candidates in the 2016 races space related questions assuming they know nothing about space.  Jim supported the idea but he told us all to make the question broader than just what interests us in the space industry. He gave several examples of this.  What he said made sense to me so I urge all of you who get a chance to question a 2016 candidate, ask your space question the way Jim suggested.

We welcomed back Buzz Aldrin to discuss his Unified Space Vision (USV) including Martian settlement, plus his new book, “Mission To Mars: My Vision for Space Exploration.”  Leonard David was the co-author of the book.  Visit www.buzzaldrin.com for more about the book and new, upcoming projects related to the book and the Aldrin vision. The book is available as hardback and as an e-book. If you use either of these links with Amazon to buy the book, Amazon will make a donation to The Space Show/OGLF: (hardback) www.amazon.com/Mission-Mars-Vision-Space-Exploration/dp/1426210175/ref=onegiantlea20 and (Kindle) www.amazon.com/Mission-Mars-Vision-Exploration-ebook/dp/B008EDPMB2/ref=onegiantlea20.  During our 94 minute program in one long segment, Buzz started out by describing his Unified Space Vision (USV) and its five main components, exploration, science, development, commercial, & security.  Buzz also introduced us to the United Strategic Space Enterprise (USSE) which forms a integral part of his Mars vision.  We discussed the role of China, India, Russia, the ISS, and why we should not engage in a Moon race with China.  In fact, part of the USV includes an international lunar post but not publicly funded by American taxpayers.  John in Hawaii asked about PISCES validating INSITU technologies, then Buzz was asked to explain his Mars cycler concept and orbits.  Following this discussion, Dr. Rowe called in to raise specific human factors health concerns regarding dust issues, Moonwalker astronauts EKG results, and down the road genetic modification for long duration spaceflight and settlement.  I then asked Buzz about the role of space tourism in his vision as well as the need for SLS.  Dr. Paul Deer called in from Cambridge in the UK to ask Buzz about risk taking.  Listeners emailed Buzz about the proposed NASA asteroid retrieval mission which Buzz said was a distraction.  Don’t miss his comments on this issue.  Another listener wanted to know why Phobos rather than Mars.  We talked about the ILDC and the concept of the international lunar base as a stepping stone for going on to Mars.  We also talked about more uses for the ISS, including inflatables, to support the USV.  Near the end of the show, John called Buzz to inquire about the space exploration contribution to student7 youth inspiration, STEM, and science development.  Buzz confirmed all of these as beneficiaries of space exploration and development.  I urge you to read this book and check back at the Buzz Aldrin website for updates and book/USV related projects.
