Guest: Dr. Steven Howe. Topics: space nuclear power for power & propulsion systems, & radioisotope power generators. You are invited to comment, ask questions, & discuss the Space Show program/guest(s) on the Space Show blog,
. Comments, questions, & any discussion must be relevant & applicable to Space Show programming.

You will want to follow the websites along with our guest:
& www.usra.edu. If you are interested in the CSNR 2012 Summer Fellowship Program, you can learn more & apply no later than March 9, 2012 from CSNR at
. We welcomed Dr. Howe to the program to discuss space nuclear power. We started out with an overview of both the Center for Space Nuclear Research & the Universities Space Research Association. Dr. Howe then told us that they were working on nuclear rockets with the Aerojet Corporation, focusing on a new fuel form away from based on tungsten. During our discussion, he had much to say about this fuel, its advantages, & its testing. He also talked about ISP & thrust to weight ratios. He was asked about testing & we learned they plan on doing ground tests at the Nevada Test Site. Listen to why their tests will be different from earlier nuclear rocket engine tests & how they are expelling the exhaust into the ground. You will hear There is no radiation, only hydrogen which bleeds into the rock strata. We also talked about public concern for nuclear power in space, then we shifted our focus to a nuclear rocket mission to Mars. Dr. Howe told us about the three year Mars mission but also said with a nuclear rocket a one year mission would be possible. We also talked about the costs for developing the nuclear rocket as well as the possibility of other countries doing it before the U.S. Next, we talked about the use of uranium & even the possibility of thorium, including why thorium is not useful for weapons. One listener question asked about the Mars Direct method & insitu resource utilization. Dr. Howe supported the use of insitu but suggested it for later trips as it might be too risky for the initial trips. He then described their Mars Hopper project which will certainly interest us all. As this segment ended, we talked about using the nuclear rocket for going to the Moon & for a lunar & even Martian habitat.
As we started our second segment, Dr. Howe was asked if QuickLaunch could be useful. Dr. Dewar sent in a clarification note about U-233 as a byproduct of thorium & why its a problem for weapons. In talking about a lunar habitat, Dr. Howe told us about the NASA Fission Surface Power Program (FSP). We also talked about using the new tungsten fuel for habitats. He told us about the Nuclear Thermal Mars Sample Mission Study that compared the nuclear rocket to Delta IV launches. Listeners asked about Vasimr & our guest was asked to clarify for us the differences between nuclear electric propulsion & nuclear thermal propulsion & why the latter is preferable. Dr. Dewar sent in another note to talk about Y-12. Later, much was said about plutonium & its pending shortage. Make sure you hear what Dr. Howe had to say about this looming shortage. Near the end, Dr. Howe mentioned his efforts with Hbar Technologies, LLC, suggesting that possibly using these nuclear advancements for medicine, specifically cancer, might be a driver for space applications. As we concluded, Dr. Howe told us about his books on Kindle & the consolidated all in one book, “Earth Rise.” Here is the Amazon URL & remember, if you buy it using this URL, Amazon contributes to The Space Show: www.amazon.com/Earth-Rise-ebook/dp/B005LD3LYS/ref=onegialeafou-20.

Dr. John Brandenburg, Tuesday, 11-22-11
Guest: Dr. John Brandenburg. Topics: We discussed his new book, the GEM Unification Theory, gravity, propulsion and more. You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog,
. 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 check out our appeal at
. We welcomed Dr. John Brandenburg back to the program to discuss his new book, “Beyond Einstein’s Unified Field: Gravity & Electro-Magnetism Redefined.” I urge you read his paper published in the Journal of Cosmology. “A Derivation of the Newton Gravitation Constant and the Proton Mass From The GEM Unification Theory of Baryo-Genesis” at
. Dr. Brandenburg & I have been friends for a very long time & our discussions are informal, sometimes meandering, & always great fun. At times this discussion was heavy into the physic so do bear with us. In segment one, Dr. Brandenburg said that the GEM theory was a “theory of most stuff.” He referred to the Gravitational Constant & the Planck Scale as well as the Middle Scale throughout the discussion. He provided the groundwork relating to Einstein and quantum mechanics, hidden dimensions, string theory, the 5th dimension, electro-magnetism & gravity theory. He also referenced many times over the Kaluza-Klein theory & work by Sakharov. An early question asked our guest to explain why there were different intensities of gravity on different planets. Dr. Brandenburg talked about Big G, all matter being electromagnetic at the molecular level & ratios (with Earth) used to predict the surface gravity of a planet made of rock. In our second segment, Dr. Brandenburg went into more detail about his GEM theory which is also referred to as the Grandis et Medianis theory. The Big Bang was discussed as well as what happened in the second before the Big Bang. He also talked about string theory & its relationship to the GEM Theory. A listener asked about the recent faster than light neutrino experiments. The experiment named OPERA was very simple & basic & most interesting. In discussing this experiment & its results, he introduced us to tachyons which prompted a call from listener John in Atlanta & they spent some time discussing the physics of the GEM theory & what it might mean for propulsion. To simplify this review, we now move forward to the need for portable fusion power & using gravity modification for space transportation. While optimistic for gravity modification, Dr. Brandenburg was blunt in saying that without portable nuclear power, even with gravity modification, we would not leave the atmosphere & we would continue using big chemical rockets. Don’t miss this discussion. We talked more about string theory & dimensions & then a listener asked about parallel dimensions. Dr. Brandenburg had much to say on this topic as well. Near the end of our two hour discussion, I asked our guest about his next book & this opened up a different discussion line. Dr. Brandenburg is going to write about science, religion, the Middle East, Israel, ancient history, Greece, the Roman Empire & metaphysics before physics! Look for him to be a guest on the show about this one. We ended our show talking about thorium, thorium reactors, why thorium cannot be used for weapons, & natural nuclear events in Africa & on Mars which he discussed in detail when he was last on The Space Show.
