We welcomed Kelvin F. Long to the show to discuss both his new book, “Beyond the Boundary” and interstellar human spaceflight.  During the first segment of our 1 hour 51 minute show, Mr. Long introduced his book which has been published on http://www.lulu.com by The Initiative for Interstellar Studies.  We discussed the book and many of the contributing authors, then I asked our guest if we might have interstellar starships next century.  Mr. Long said it was possible but also a very big problem so you do not want to miss this comprehensive discussion.  During this segment, we addressed warp drive, worm holes, negative energy, and public sector responsibility for interstellar spaceflight.  Kelvin provided us with some interesting history going back to the 1930s and the British Interplanetary Society (BIS) early work about rockets to the Moon.  Later, nuclear propulsion came up in terms of both fission and fusion technology.  As part of this discussion, Kelvin mentioned problems caused by the Outer Space Treaty. In addition, we discussed Project Dragonfly which is a laser sail competition, robotic payloads, Project Daedelus, and more.  Listener Helen asked our guest about the plausibility of a hibernation ship and BJohn asked about gravitational forces of the Sun and interstellar travel.  John called from Ft. Worth to seek a clarification about the Outer Space Treaty comments and to talk about NTG usage in space.

In the second segment, Kelvin talked about Project Icarus and directed us to http://www.icarusinterstellar.org.  We also talked about the growing interstellar community and some of those in different industry segments working for and supporting interstellar travel.  Tim called to ask about the fission fragment rocket and Mach’s thruster.  BJohn asked about ET civilizations and the Fermi Paradox.  Kelvin had much to say on this subject.  Near the program’s end, I asked Kelvin for an action plan. He proposed one covering three areas:  Education, Business, and New Technologies.  Make sure you here the details of his plan.  Our guest offered us powerful closing comments.

We welcomed Dr. John Brandenburg back to the show to discuss his new book, “Death On Mars: The Discovery of a Planetary Nuclear Massacre” & the giant nuclear explosion on the surface of Mars.  Please remember to purchase the book through the OGLF/Space Show Amazon portal so Amazon will contribute to The Space Show. Contact me for added instructions if necessary.  In our first segment of our 1 hour 44 minute program, Dr. Brandenburg outlined the hypothesis behind the theory that there was a giant nuclear explosion on Mars a very long time ago that blew away most of the Martian atmosphere.  He cited evidence given the presence of Xenon 129 in the Martian atmosphere along with the presence of thorium and potassium around Mars.  He suggested listeners look at the Martian thorium and potassium distribution points by searching the maps that are widely available online.  Listeners had lots of questions about all of this, especially since Dr. Brandenburg estimated the size of the two explosions to be equal to something on the order of the Empire State Bldg, or a billion megatons.  We contrasted this explosion size with the largest nuclear bomb exploded on Earth, 50 megatons by the Soviet Union.  Furthermore, because of the size of the explosion, he suggested this was not a natural nuclear explosion but a weapon of some sort regardless of how impractical that might sound.  He also explained how the size and quality of the explosion could be calculated.

In the second half listeners had more questions.  Dr. Brandenburg agreed to send me his Journal of Cosmology article which I will upload to the blog when I archive this program.  The article is titled “Evidence of a Massive Thermonuclear Explosion on Mars in the Past, The Cydonian Hypothesis, and Fermi’s Paradox.”  Later in the segment Dr. Brandenburg did discuss the Fermi Paradox, the Cydonian connection and Mare Acidalium.  Before the show ended, John talked about his science fiction books and the latest one he is working on which will be out sometime this year.  John writes science fiction under the name Victor Norgard.

Please post comments/questions on TSS blog above.  Don’t forget to read Dr. Brandenburg’s reviewed paper on he blog.  You can contact Dr. Brandenburg through me.

We welcomed Lee Billings to discuss his new book, “Five Billion Years of Solitude: The Search For Life Among The Stars.”  During the first segment of our 90 minute program, Lee introduced us to the book and its main topic, plus he told us why he wanted to write this book.  He talked about his interest in the subject dating back to his childhood.  He also wanted to ask and explore questions like what makes exoplanets have a habitable zone, what about parallel universes, the multi-verse, and more.  He talked about finding O2 in the atmosphere and wondering if it would be replenished and does that mean life?  He talked about the need for big telescopes, in space on and Earth.  Listeners asked him several email questions about the Drake Equation, the Fermi Paradox and the Allen Telescope Array in N. California which is part of SETI.  Near the end of the first segment, Lee talked about competition in searching for exoplanets.  Also, we talked about the American public and policy makers under valuing space and the specific topics of today’s show.  Right before the break we took a call from John in Ft. Worth who put the search for life in the context of the laws of physics and the limits of technology.  John also brought up human factors, asking how that might impact the search for life.

In our second segment, Lee talked more about the Drake Equation and the old TPF program (terrestrial planet finder).  We talked about different possible pathways and the work of ESA and JAXTA,  Other topics in this segment included cross cultural analysis of who supports space and why, viewpoints other than the NASA viewpoint, then I asked him for his favorite interview in the book.  Lee mentioned several people included in the book but settled on Jim Kasting.  Listen as to why this person was his favorite.  Karen emailed in to ask if he asked his subjects how they thought confirmation of life other than on Earth might impact us here on Earth.  He was also asked for his view of progress ten years from now.  Our guest had much to say about this time line.  In his concluding comments, the question was asked about our being special or privileged.  Also, we need better opportunities for better stewardship of our planet.

We welcomed Dr. James (Jim) Benford to the program to discuss his book (he was the co-editor) “Starship Century,” and his chapter, Sailships, plus his editing of the book.  During our first segment of this 1 hour 26 minute discussion, Dr. Benford introduced us to Microwave Power Beaming, sailships, solar sails, terrestrial beamed power, in-space beamed power and more.  We talked about microwave beaming as a possible space weapon, the storage of beamed energy, and the use of the millimeter band width for beamed power.  Also in our first segment, we talked about possible time lines for development for interstellar travel.  In this discussion, our guest used Alpha Centauri B as a reference point.  Propulsion in general was discussed with a thumbs down for chemical rockets for doing anything like what we were talking about in this segment.  Listeners asked questions as to why interstellar travel was important at this time given it is so far into the future.

In our second segment, we talked about his goals in editing the book and the fact that if it is bought through the book’s website, www.starshipcentury.com, the proceeds are donated to legitimate interstellar organizations and research.   Jim listed several of the organizations being considered for receiving such proceeds and interestingly, most if not all have been guests on The Space Show over the years.  Dr. Benford mentioned conferences and the Arthur C. Clarke Center at UCSD.  We then talked about the Fermi Paradox and factor L as to the probabilities of finding intelligent life someplace other than Earth.  Faster Than Light Travel was a discussion topic, Jim was asked what his non-space friends thought of his microwave beam power work and interstellar travel.  A listener asked about students in these subject, particularly in the UK and the US.

We welcomed Dr. Paul Davies to this 65 minute discussion about his contribution to the excellent book, “Starship Century: Toward the Grandest Horizon.” Other topics included interstellar travel, microbiology, human spaceflight, Mars, ET and much more.  We started our discussion with his Afterword in the “Starship Century” book and I asked him about his comments regarding microbes.  One quickly learns from reading his Afterword that it is not the propulsion and engineering that presents the greatest challenge to interstellar travel but what happens to essential microbes needed for life in microgravity and the space environment.  We learned that even in LEO such microbes can transform and become toxic to life.  This is a fascinating microbiology discussion regarding deep space missions to Mars, the Moon, and long interstellar travel. Don’t miss what Dr. Davies said about microbes as it opens up an entirely new study in human factors for human spaceflight.  Other issues we talked about included planetary contamination, microbial ecosystems, figuring out the minimal needed for sustainability regarding the good microbial environment.  Also, what microbes are crucial and those that might be irrelevant for the spaceflight passengers as well as for animals and plants needed for sustaining the mission.  Dr. Davies was asked that given microbiology being a bigger challenge than propulsion and engineering, were we close to having propulsion and engineering for interstellar travel.  You will appreciate his very “witty” answer to this listener’s question.  Faster than light travel came up and so did the work being done around the Alcubierre Drive.  Dr. Davies had much to say about faster than light travel, the speed of light, physics, and related disciplines.  In this discussion, we also talked about both black holes and worm holes.  Later, we talked about the possibility of life in the solar system other than on Earth.  You might be surprised by some of what Dr. Davies said, including the probabilities that Earth might have been visited over 100 million years ago.  Don’t jump to conclusions, listen to the discussion first.  Helen of Atlanta asked why bother with interstellar travel when we can’t even return to the Moon. Again, another terrific response by our guest.  More came up on the Fermi Paradox, the need to stay grounded in fundamental science but to have a vision and healthy skepticism.  Viking and Gil Levin came up regarding the possibility of life on Mars and the reluctance of NASA to do biological experiments regarding the possibility of life on Mars.  A listener asked our guest about ET conspiracy theories and government cover-ups.  In closing, Dr. Davies reminded us to have and conduct healthy speculation which means always staying in tune with fundamental science.  That is what separates speculation from fantasy, Kool Aid, and La La thinking.  As the program was ending, we talked some about his work in cancer research.
