We welcomed Dr. Paul Spudis back to the program for a 2015 space year in review. During the first segment of our 1 hour 31 minute discussion, we covered much ground reviewing key events of 2015 including European, Russian, & Chinese space accomplishments & missions. Dr. Spudis got several emails on a wide range of topics from space advocate rhetoric to Orion, CST 100, Dragon V2 and more. Regarding advocate mission plans and projects, he said the technology people talk about and want to use in their various space mission designs does not really exist. He used going to the Moon to harvest water ice for water and fuel as an example of where we are today. That said, he indicated that there are only so many wants to do certain types of space projects so it was likely that which advocates called for could end up in actual mission plans and real projects. Budget issues were also discussed as well in this segment. Listener Christa asked if the return to the Moon and cislunar development will become a future policy priority. Dr. Spudis had much to say on this topic so don’t miss it. This included the possible impact of the 2016 presidential election on space policy. Jeff in Boston inquired about the aging process and other human factors as challenges/obstacles to doing BLEO projects. Dr. Spudis offered us an interesting perspective on the human factors issues. Jack in Portland inquired about our guest’s views on asteroid mining and the language used in the new commercial space law recently signed b the president. Our guest shared his views with us on these issues. We talked public-private partnerships and government procurement. Kim called from Mexico to inquire about the Lalande Crater on the Moon & the cracks or fissures seen in the photos, plus impact melt and more. She also talked about young and old craters which Paul defined for us upon my request. A young crater would be less than a billion years old! Near the end of the segment Paul talked about the challenges in closing a business case for going to the Moon at this time, plus the proper role for government in this situation. Sandra asked about the lunar space elevator.

In the second segment, Kim called back to inquire some more about Lalande crater, thorium bright spots, and more. BJohn emailed in asking about lunar landers, then Rodney brought up space settlement. Paul had interesting comments on space settlement you will wan to hear. A good portion of the second segment was spent on Mars. Back to the budget, he said the challenge was to do more in the most efficient ways possible while reducing the need for more funding. The Mars-Moon debate came up again with Paul explaining why returning to the Moon before going to Mars was important Solar power for missions and habitats was discussed along wit ISRU usage. Don’t forget to reach Paul’s article on Air and Space about the asteroid mining section in the Commercial Space Law just signed into reality by President Obama. See Paul’s writings at www.airspacemag.com/author/paul-d-spudis/?no-ist as well as at www.spudislunarresources.com.

We welcomed Professor Sara Seager of MIT to the program to discuss exoplanets and the science behind finding them along with the search for life and Earth-like planets.  For more information, visit her website, http://seagerexoplanets.mit.edu.  In addition, Professor Seager has a free ebook available for download on her website, “Is There Life Out There.”  You can download this ebook at http://seagerexoplanets.mit.edu/ProfSeagerEbook.pdf.  During the first segment of our 1 hour 27 minute discussion, Professor Seager started with a working definition for exoplanets and the techniques used to find exoplanets.  We also talked about planet habitability, the habitable zone, Kepler planets, ground based telescopes, direct imaging, the Gemini Planet Imager, and the potential involvement of amateurs & their telescopes in the search for exoplanets.  Many listener questions came in by email. One focused on SETI which led to an interesting discussion with our guest.  Professor Seager provided us with comparison statistics for various planets and their size and characteristics, and we talked more about the best exoplanet finding methods.  Our guest told us about “ExoplanetSat,” a 3U CubeSat capable of high precision pointing with a goal of detecting small transiting exoplanets orbiting bright, sun-like stars.  We then discussed CubeSat photography & cameras and more about the need for precision pointing.  Professor Seager received several questions about budget and NASA issues, then Doug called in with excellent questions about exoplanets that you do not want to miss.

In the second segment, we talked about Professor Seager’s ebook on her website, “Is There Life Out There,” plus our guest responded to an email question from Nathan about the “Rare Earth” hypothesis.  We then talked about the KST problems and the new mission for the space telescope referred to as K2.  John form Ft. Worth called to ask about conceptual and technological advancement & breakthroughs in the field.  I asked our guest what she thought the field might look like in ten years plus I asked her why rocky planets were important for finding exoplanets.  Charles Pooley called to ask about photometry, LEO, & related issues.  As our program was ending, I asked Professor Seager to share with us some of her media experience and thoughts about the quality of science reporting.

Please post comments/questions on TSS blog.  I will be happy to pass on your emails to her if you send them to me.

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 Kimberly (Kim) Arcand and Megan Watzke to the program to discuss their new book, “Your Ticket To the Universe: A Guide To Exploring The Cosmos” published by Smithsonian Books.  Visit their website for more information our guests and this amazing book, www.yourtickettotheuniverse.com/Index/Home.html.  Also check out this YouTube video for the book, www.youtube.com/watch?v=3-KamC0Plro.  If you order the book using this Amazon URL, Amazon will make a contribution to The Space Show:  www.amazon.com/Your-Ticket-Universe-Exploring-Cosmos/dp/1588343758/ref=onegiantlea20.

During the first part of our 90 minute discussion, our guests explained why they wrote this book and how they came up with its unique structure, format & famous person quote at the beginning of each chapter.  We talked about the pictures used in the book and a few of the items that stood out to me including “Taking an Alien to a Baseball Game” which helps us understand visible light along with all of the other types of light.  A listener with a copy of the book emailed in to ask about the use of the terms light second, light minutes, and light hours when describing objects in our Solar System.  Their discussion of Pluto as a dwarf planet came up in addition to my talking about the book as an excellent teaching tool for school libraries, students of all ages, even adults.  Our authors talked about art and I noticed the inclusion of the famous painting Starry Night in the book.  Don’t miss what Kim and Megan had to say about why Starry Night was used in their book and the overall subject of art, space science, aesthetics, and the night sky abundant with stars.  As our segment was ending, we talked about Mars analogs here on Earth such as Svalbard and Rio Tinto among the many Earth Mars analogs referenced in this book, plus the book’s astrobiology focus.

In our second segment, I asked our guests if space exploration was worth it and why.  Don’t miss what each had to say in answering the question.  We talked about the NASA budget, what is accomplished with the budget, and general population misunderstandings about the actual amount of the NASA budget.  I mentioned a TV documentary on the Dutch East Indies Company and the necessity of human exploration.  I asked our guests what they thought our world would look like had we sent robots out instead of humans in those very early and risky exploration missions.  A listener asked about the description of the book as both a coffee table book and a science book, and we talked about that hybrid description.  Near the end of our discussion, I asked each guest for their favorite place mentioned in the book where they would want to hang out.  You might be surprised by their choices.  Both Kim and Megan signed off with excellent closing comments that you will want to hear and remember.

If you have comments/questions, please post them on The Space Show blog.  You can contact both guests through their website, Twitter, and Facebook, as well as through me.

Dr. Chris Impey, Sunday, 4-15-12

http://archived.thespaceshow.com/shows/1752-BWB-2012-04-15.mp3

Guest:  Dr. Chris Impey.  Topics:  We discuss Dr. Impey’s new book, “How It Began: A time-Traveler’s Guide To The Universe” along with astronomy, physics, and cosmology topics. We also discussed space policy and the future of human spaceflight plus science missions. 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. Chris Impey back to the program to discuss his new book.  Remember, if you buy the book from Amazon using the following URL, Amazon makes a contribution to The Space Show/OGLF:  www.amazon.com/How-It-Began-Time-Travelers-Universe/dp/0393080021/ref=onegiantlea20.  For the Kindle version, use www.amazon.com/How-It-Began-Time-Travelers-ebook/dp/B005LW5J30/ref=onegiantlea20.  During the first half of the program, Dr. Impey talked about the book’s structure which is a bit different from other books addressing similar topics.  For example, the further outward in the universe you go via reading the book, the more backward in time you go which is why the book is a time-traveler’s guidebook to the universe.  Dr. Impey explains this to us and the going back in time is with us for the entire Space Show discussion.  Our first stop was our Moon and our guest had much to say about it, including its origins, why and how it orbits Earth at about 240,000 miles, and more.  We also learned what Earth would probably be like without the Moon.  As we went into deeper space after leaving the Moon, we talked about the Kepler Space Telescope (KST) and finding exoplanets plus searching for exomoons.  A listener asked about the delay encountered with supernova 1987A and our guest explained this to us.  I also asked our guest about his statement on page 19 at the bottom about time and Apollo becoming a “distant cultural memory.”  This turned into a lively discussion you don’t want to miss.  We then talked about human spaceflight (HSF) with Dr. Impey suggesting that due to the high cost of HSF and the constant improvements with robotics, we might very well see advanced robotic missions over the coming years rather than human missions which may prove unaffordable.  Don’t miss this conversation, it may very well be an accurate forecast for the future for HSF and robotic missions.

In the second half of our program, we moved out into the universe and talked about the Big Bang, First Light, and the James Webb Space Telescope (JWST).  We also talked about large Earth-based telescopes, Hubble, and looking back close to 13 billion years with JWST while the universe is about 13.7 billions years old.  We talked about why one cannot see the origins of the Big Bang with optical telescopes, but what we can “see” with microwaves.  A listener asked about the Cosmological Principle and another asked about human time travel.  This brought up the topic of black holes.  Questions came up about string theory and the Multiverse, and then John called in to discuss both dark energy and dark matter which turned out to be another fascinating discussion led by Dr. Impey.  Later, we went back to discussing HSF and we learned about the potential for nanobot probes for interstellar missions.  Fleets of such probes acting in a sort of relay fashion might just be real someday.  Near the end of the program, Dr. Impey discussed geopolitics as a driver for space exploration and said more about the early time after the Big Bang for the first 100 million years or so.

Guest:  Dr. David Kipping.  Topics:  Searching for Exomoons and Exoplanets with Kepler Space Telescope (KST).  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. David Kipping to the program to discuss the search for Exomoons and Exoplanets.  The primary tool for these searches is the Kepler Space Telescope (KST).  We talked about the methods used to search for the exomoons, mainly planet transits.  Later in our discussion we talked about the other methods including detecting wobbles and using pulsars.  Another discussion issue was the fixed field of view for the KST (about 10 degrees) and the benefit of having multiple KSTs to look at different and broader fields of view of the sky.  Dr. Kipping was asked several questions about finding exomoons in the habitable zone (Goldilocks zone). We also discussed the randomness of targets and the small number that are actually in the field of view from Earth.  Charles in an email brought up spectroscopy in the searches. 

In the second segment, we started out discussing pulsars and their role in these searches.  Dr. Kipping went into some detail to explain to us the radiation pulses and how they can be interpreted in the exoplanet/moon searches.  As you will hear, pulsars are not likely to be located in the Goldilocks zone but Dr. Kipping did give us an idea of the best targets for a visit were we to have interstellar space travel.  Later we talked about the JWST and infrared searches along with the potential the JWST brings to astronomy.  This discussion took into account the NASA budget, competition with the science missions and human spaceflight, and making hard choices for this or that funding.  Our guest took some listener questions about nanosatellites and swarms of mini-KSTs.  Dr. Kipping had much to say about this idea, including that it was a good one.  Another issue covered was the international effort in these searches.  I asked our guest about amateurs and planet searches. He told us about an interactive website, www.planethunters.org plus other programs that involved non-professionals in the searches.  Near the end of the program, Dr. Kipping discussed the differences with the KST public data and private data.
