We welcomed Dr. Don Lincoln back to the show to discuss his new book “Alien Universe: Extraterrestrial Life in Our Minds and in the Cosmo.”  During the first segment of our 1 hour 29 minute program, Dr. Lincoln discussed why he wrote this book, especially given his position as a senior scientist at the Fermilab plus his work in Cern at the Large Hadron Collider. After the introduction, he took us through major events, both physical and cultural that have fueled alien interest including the Betty and Barney Hill case, Roswell, and more.  He took us through these events with an actual historical timeline which put the events in a somewhat different perspective than we are used to hearing.  We also talked about the Drake & Fermi equations and the seven parameters of the Drake Equation, many of which have been upgraded due to new scientific information coming to light in recent years from the Kepler mission and other tools/events.  SETI was a topic of discussion as was the use of radio waves and light for ET detection.  The subject of alien abduction came up and Don pointed us to the 1835 media buzz known at the moon hoax appearing in the first tabloid style newspaper.  This was an interesting history lesson that was new to me and probably to many listeners as well.  Marshall called in to talk about Drake radio waves, the signal to noise ration, and a planet being either too close to the center of the galaxy or too far from the center of the galaxy which causes the planet to be a metal poor planet. Dr. Lincoln had much to on this subject.  Next, we talked about microbial life on Mars.  John from Ft. Worth called to talk about impractical physics given the need to cross interstellar space. Don agreed and talked about the possibility of using probes.;  The subject of technology & options such as a mother ship plus scout ships came up.  John and Don talked about the lack of objective studies and the difficulty in working with assumptions.  Don also talked about the high standards used in science which are hard to apply to the alien visitation theories.  Scientists are not usually inclined to lower their standards so true scientific studies on alien visitation are a challenge.

In the second segment, we talked about the Roswell event.  Our guest had much to say about this event so don’t miss this part of our discussion.  Some scientific studies were mentioned such as Project Blue Book. I asked about studies by other nations and scientists outside the U.S. We came back to microbial life off Earth which is an important study subject by scientists across many nations.  Near the end of the program, Dr. Lincoln talked about the idea of First Contact, Star Trek, and comments made by Professor Stephen Hawking.  In the concluding minutes of our discussion, I asked our guest about part of his subtitle, “Life in our Minds” & Don talked about how this subject has come to our minds.  He left us with a good summary and strongly urged us to separate sociology issues from astrobiology, the latter being a credible science in search of life off Earth.

Please post your comments/questions on TSS blog above.  You can reach Dr. Lincoln through me.

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.

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. 

Please post your comments on The Space Show blog.  If you want to send a note to Dr. Kipping, please do so through me at drspace@thespaceshow.com.

Guest:  Robert (Bob) Zimmerman.  Topics:  Space Act Agreement, private compared to government space, Kepler planet discovery, bats.  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. The Space Show/OGLF is now engaged in its annual fundraising drive. Please see & act upon our appeal at https://thespaceshow.wordpress.com/2011/11/21/space-show-2011-fundraising-campaign.  Merry Christmas to all of you from The Space Show.  We welcomed Bob Zimmerman back to the show for policy, news, and bat updates.  Make sure you visit his blog for interesting and timely news and posts, http://behindtheblack.com. We started our two hour discussion with Bob saying that NASA reverting back to using the SAA instead of the FAR was perhaps the most significant moment in space since the Apollo landings. Listen to his explanation which he talked about multiple times during the program. Do you agree?  In talking about the SAA, we also talked about the new NASA budget of $406 million for crew, including the amounts already allocated, leaving about $100 million less for the companies.  We talked about the need to have launch competition with at least two companies.  In addition, since NASA will “certify” the private HSF vehicles, we talked about what that might be like and the continued control over the companies by NASA.  As you will hear over and over again, Bob does not look favorably on government space programs and believes the future is to be found within the private sector.  Do you agree with Bob?  Another point Bob made in discussing the SAA was that it probably sounded the death knell for SLS.  Again, listen to what he had to say on this subject.  Kelly called in and sent us information about another effort to commercialize the remaining two space shuttles.  We talked about this and similar plans in detail.  The new Stratolaunch concept came up and Bob got a few questions about air launch and the performance gain from doing an air launch. Our discussion closed in the management team involved in the project as being a “dream team.”  In the second segment, we talked about the new Earth-like planet discoveries by the Kepler Space Telescope, including two in the habitable zone.  Later, we talked about human rating the Atlas and Delta rockets, and the DOD-ULA deal which may not happen.  Listeners asked Bob about the Russian space program in light of Phobos-Grunt, about SETI, and even possible one way missions to Mars.  Alistair asked about the possible impact on US policy makers if China was about to go to the Moon & establish a lunar base.  Later we talked about Telstar, ATT, airmail, and space politics..  We concluded with a bat update on White Nose Syndrome.  Bob suggested three areas to look for in 2012: the Falcon 9 launch, the test flight of Antares, and Virgin Galactic SS2 engine tests and flights.  Please post your comments and questions on The Space Show blog URL above.
