During the first segment of our 97 minute program, Dr. Sutter opened up with a detailed discussion of the big bang theory and the physics and science to go along with it and support it with scientific evidence.  Almost the entire first segment was devoted to this comprehensive discussion.  We talked about proof, theories, truth, alternative ideas and scientific evidence including the cosmological microwave background light which is the oldest light in the universe.  Paul described this in detail, explained that it was really microwave radiation and how it supported an expanding universe.  Rather than summarizing this segment in detail, I urge you to listen to this show because it is one of the best ever Space Show science shows and discussions.  In my opinion, Dr. Sutter is gifted in his ability to explain complex scientific theories and concepts in ways that those of us who are not scientists can grasp and understand facts, scientific evidence, and theories.  In addition to the science, several listener questions came up along with mine about the meaning of certain words in use by the general public as compared to a scientist.  This was a very illuminating discussion and I think you will agree when you hear how theory, fact, truth, plus other words are used in science and what they mean to a scientist  as compared to how we use the same words in our daily vocabulary and word use.  BJohn asked questions about star formation and John from Ft. Worth called and added to our scientific discussion given his physics expertise and knowledge.  I personally want to thank him for his two calls which advanced the quality of our discussion, especially about an open and closed universe.  Then our guest added a third possibility, a flat universe.  Don’t miss this part of our program.

In our second segment, we talked in more detail about Dark Matter.  This too was an example of the clarity given the topics by our guest so listen carefully and enjoy and appreciate how something so complex can be made so easy for us to grasp and understand.  Later in the segment, a listener asked about the impact a TV show like The Big Bang Theory might have on people given the way it portrays “scientists.”  As this was one of my favorite TV shows, I entered the conversation and had a different set of thoughts about its impact than did our guest.  Listen to hear what we both had to say about it.  As I said on the show, in the 2,571 programs I have done to date, plus with all the scientists and engineers that I have met in person at conferences and elsewhere, I have yet to meet a real scientist or engineer that even comes close to being in real life the way the four Big Bang TV Show guys are with their personalities and science.  They are extreme over the top whacky characters that I really enjoy.  We also talked about famous scientists coming on the show for cameo appearances and always playing a role supporting the four nerds.  Paul and I had a great discussion about the show and its impact so don’t miss it, especially if you watch this TV show.  Near the end of our program, we talked about real life science labs as compared to those seen in big hit movies and TV shows with lots of CGI and design added to them.  Dr. Sutter talked about science outreach, his target audience for his outreach, and why he chose his targeted audience.  Just before the show ended, Ft. Worth John called back to reference dark matter with gravity.  An excellent way to conclude our program.

We welcomed Emily Lakdawalla to the program to discuss space science missions, The Planetary Society, space & outer planet geology.  During the first segment of our 90 minute program, Emily went over her background and how she came to have an interest in space and in particular space science and geology.  Some of our topics included the tectonics of Venus, asteroid mining, her interest in the outer planets of the solar system, and science missions either ongoing or to be conducted in the future.  I mentioned a possible Europa mission which led to a Europa discussion and Emily talking about the ESA JUICE mission (JUpiter ICy moons Explorer).  We talked about being able to cut the travel time to the outer planets for science missions and our guest mentioned the possible use of SLS to do that.  Don’t miss this discussion.  Also in this segment, we talked about upcoming comet and asteroid mission, then we switched gears to discuss robotic challenges.  Here, Emily pointed out the time lag for communications to Mars and beyond makes telerobotic control difficult at best.  We talked about having a Mars orbiter to control surface robots.  Were we doing this, the robots could be simpler as they would not need as much autonomous capabilities as they need now based on Earth communications.  Emily told us about Planetary Society projects and programs, we talked about man in the street interviews regarding space & our guest shared her experiences with us when Shuttle Endeavour came to Los Angeles.  Near the end of this long segment, Kepler came up, questions came up about Earth geology being similar to the geology of the planets, the lack of fossil fuels on other planets, then Doug called with a question about coalition building & the NASA science budget.  As the segment ended, we asked Emily about robotic exploration as compared to having a human geologist on the surface of the planet. BJohn from Sweden sent us emails about Curiosity on Mars and Venus.

In our second segment, we talked about relevant time spans and how missions get prioritized.  Emily went over the Venus challenges.  She was asked if the Planetary Society would try another Phobos-Grunt mission and we talked about their project, the Mars Microphone to bring back to Earth the sounds from Mars.  Toward the end of the program, Emily was asked about the importance of lowering launch costs for science missions and the promotion of space advocacy.

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. Paul Abel to the program to discuss the BBC television show, The Sky At Night (www.bbc.co.uk/programmes/b006mk7h).  During the first segment of our 1 hour 31 minute program, Dr. Abel introduced us to the Sky At Night show which was started by Sir Patrick Moore in April 1957.  Dr. Abel described the focus and objectives of the program and we talked about some of their projects including the “Battle of the Forces” tug of war video which is on their website, plus their just completed Summer Solstice program which was filmed at Stonehenge.  We came back to talking about Stonehenge, mythology, rituals, and customs many times throughout the discussion.  I asked Dr. Abel about British commercial space companies such as Surrey Satellite but since they are publicly funded, their focus and goals are different as they address mostly space and science topics.  Dr. Abel talked about the many British astronomical societies plus the overall interest in astronomy and these societies within the UK.  We talked some about human spaceflight, including the Mars One venture.  Listeners asked about astronomy and telescopes and we learned that our guest is not in favor of what he called “go to telescopes.”  Instead, he suggested we should learn how to map the night sky and navigate our way around it with an equatorial telescope.  Listeners also wanted to know about observing and dark skies in the UK.  I asked questions about the relationship of astronomy and theoretical physics.  Another listener asked for a definition of Hawking Radiation.  Comets came up along with their mythology, plus the Kepler Space Telescope and Voyager 1.

In our second segment, Ben asked about SETI in the UK.  This started a rather involved and fun discussion about ET and the search for life using radio telescopes as well as by other means.  Also mentioned in this segment was amateur astronomy as compared to professional astronomy, Star Trek & its devices such as the transporter.  Paul received questions about his home observatory and telescopes.  A possible Europa mission was mentioned and we were both excited about that potential.  I asked our guest about STEM issues in the UK & observing in London’s Regis Park.  Sine we had spent some time talking about the search for life and ET, we talked about some ET sci-fi movies including Contact, Alien, & Star Trek.  As we were about to end, Tim called wanting to ask more about Skylon, a possible UK launch site near the equator, and the emerging UK Space Agency.

Guest:  Dr. Neil deGrasse Tyson.  Subject:  Dr. Tyson talks space policy along with his new book, “Space Chronicles: Facing The Ultimate Frontier” and his article in the current edition of Foreign Affairs, , “The Case For Space: Why We Should Keep Reaching for the Stars.” You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, https://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed Dr. Neil deGrasse Tyson back to the show for a comprehensive hour long discussion on space policy, the NASA budget, investment in our future, the space race, and many more issues as pointed out in both his Foreign Affairs article and in his new book.  Remember, if you order his book using the following Amazon link, Amazon will make a contribution to The Space Show/One Giant Leap Foundation: www.amazon.com/Space-Chronicles-Facing-Ultimate-Frontier/dp/0393082105/ref=onegiantleap20.  You can read his Foreign Affairs article at www.scribd.com/doc/82592118/The-Case-for-Space.  During our hour with Neil, we discussed the NASA budget and why it should be increased.  Dr. Tyson also pointed out why humor was so important and what it really means as I asked him about the joking and kidding around regarding space when he visits programs such as The Daily Show.  Neil also made the case for more space activity and talked about spinoffs but additionally he talked about the economic growth that comes from innovation and inspiration, along with unplanned and fortunate discoveries. Here, he cited the Hubble Space Telescope and mammograms as an example.  He also suggested that with a space program that is innovative and doing what it should be doing, the STEM education problems are solved in the process.  We talked about NASA not being one of the key scientific government agencies anymore and he was upset that this was and is not being corrected.  Dr. Tyson had much to say about the role of the private sector in space development in that government typically puts down the infrastructure and opens the industry door with the privates coming after, expanding the industry, operating more efficiently, and developing markets.  A listener asked about planetary defense and asteroids, another listener inquired about space enthusiasts running for political office, and Jon suggested that giving NASA a bigger budget would just be a waste as NASA is all about pork.  Neil addressed all of these questions and more.  I urge listeners to read his book and if possible, read the Foreign Affairs article before you listen to the interview. During our discussion, Dr. Tyson said some very powerful things.  For example, note our discussion on the NASA budget as an investment, not an expense.  Neil described himself as an educator so listen to what he had to say about how to influence people and create change through education by teaching real science and facts so people can make truly informed choices.  Pay attention to what he said about a country that does not invest in its future and why space should be the future getting the investment benefit.  Throughout this interview, Neil powerfully reminded us all that even in tough economic times like today, NASA has been instrumental in shaping our national identity, inspiring us, driving our economy, driving careers in the STEM disciplines, and bringing us landmark, groundbreaking new technologies.  I personally believe that Dr. Neil deGrasse Tyson makes a very good case for space.   Please post any comments/questions you might have for Dr. Tyson on The Space Show blog URL above.
