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.
