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.

We welcomed Bob Zimmerman back to the show for this two hour discussion.  Bob started the first segment with an overview of commercial space progress to date in 2014 which includes Space X Falcon 9 launch, Orbital’s launch to the ISS, the recent Virgin Galactic demo test plus other events.  SLS came up again and unfortunately took up time throughout the show.  As you will hear me say, I am sick of the pro and anti-SLS comments on the show and really need an SLS break as I imagine most listeners do as well. Unfortunately, callers and email questioners kept bring it back to our focus and Bob was not shy on commenting on SLS as he wants it cancelled.  We talked some about Virgin Galactic and XCOR, then I asked about Dream Chaser given the news it has been seeking international partners to continue the project.  Bob was next asked about the Chinese policy and their lunar lander.  He started comparing the Chinese program of today to the early Soviet Union program and suggested that like all space programs, they will make a significant contribution to changing the culture of the country.  We talked about the new Omnibus 2014 Budget Bill before congress and the increases to NASA, planetary science, commercial crew and more.  As we neared the break, Bob in Berkeley asked Bob the guest to opine on Inspiration Mars and Mars One.  Doug from S. California called with multiple questions before the break, starting out asking about Bob’s comments on the negatives for taking government money and wanting to know if that applied to Space Act Agreement recipients.  His last question directed to Bob and me was based on our being part of the space media and about influencing policy, culture, programs, etc.  Bob’s and my response continued into the second segment.

During the second segment, Trent chatted in from Australia, then Dave called in from Chicago to asked about the J2X engine.   Bob and I talked some more about making a policy impact, then I asked Bob for key issues that will emerge for the balance of the year.  He talked about Russia competing with private companies, HSF and Dragon, astronomy, ground based telescope improvements, and NASA science programs.  At the end, I asked about the new mission for Kepler Space Telescope to have it continuing doing useful and productive research for the rest of its life.
