We welcomed Adam Crowl to the program for a one hour twenty minute discussion on interstellar travel, propulsion and technology potentials.  During the first segment, we talked about the book Starship Century and his chapter in it, “Starship Pioneers.” the early rocket pioneers and their thoughts on interstellar travel as the idea as it has has been with us and our imagination forever.  We talked about theoretical backing, actual capabilities, time lines, and more. Some of the technologies were addressed such as nuclear fusion plus some of the models he showed pictures of in his chapter in the book.  We also talked about solar sail and then I asked about human flights to Mars and the Moon as stepping stones for interstellar flight.  Antigravity was discussed along with antimatter, lasers, proton beams, and more. Our callers asked about these futuristic technologies and even the types of interstellar missions that could unfold down the road.

In the second segment, faster than light travel came up with Dr. Harold (Sonny) White and his work.  More calls came in regarding gravitational theory, particle physics, and beam propulsion.  Another John called in wondering about the accuracy of today’s interstellar speculation.  Multi-generational starships were discussed plus Adam made a point saying the profits from the book go to support interstellar research.  Check this out at the book’s website, www.starshipcentury.com.  As the program was ending, Randy sent in a note about the inspirational and motivational value of interstellar travel discussions.

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.

If you have comments or questions, post them on The Space Show blog.  You can reach Dr. Benford through his website, www.jamesbenford.com.

Guest:  Open Lines with Dr. David Livingston.  Topics:  This was a wide ranging discussion on many space topics & related issues.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://thespaceshow.wordpress.com. Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use. We do not permit the commercial use of Space Show programs or any part thereof, nor do we permit editing, YouTube clips, or clips placed on other private channels & websites. Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information.  We talked about many topics and issues on this 2 hour 40 minute program.  In the first segment, ITAR reform was discussed and Andrew of the Tea Party In Space in his discussion also advocated for the resumption of manufacturing Plutonium 238. We got caught off but he called back in the second segment.  Charles called to advocate for small markets & an incremental approach.  He continues working on Microlaunchers.  John from Atlanta called to talk about strange lights over Detroit.  We had a good time talking about the mysterious Detroit sightings which you can easily see pictures of & find out more if interested with a very simple Google search.  John also wanted to talk about our recent advanced propulsion program about warp drive and interstellar physics.  If you have not heard that program from Jan. 4, 2013, I strongly recommend you do listen to it.  Space budget, economic and sequestration issues came up in this segment as well. We also talked about the bankruptcy sale of special battery company A123 to China and the fact that this includes sensitive military technology.  Listeners expressed a variety of opinions about this matter.  Perri provided us with this Forbes story on the matter:  www.forbes.com/sites/greatspeculations/2012/12/12/china-wins-u-s-loses-in-a123-bankruptcy.  I also read a PR statement from a group opposing the sale to China.

     In our longer second segment, Andrew called back and we talked about economic issues in congress, SLS, Golden Spike, and building relationships with staffers in congress to better advocate for space.  Tim called from Huntsville to tell us about the absurd PETA, Elon Musk and vegetarian issue arising about the food people will eat on Mars. You can read about it at these locations:  http://rt.com/usa/news/space-mars-musk-people-595 and http://betabeat.com/2013/01/elon-musk-would-like-you-to-know-i-am-not-the-kale-eating-overlord-of-mars.  Based on this story, we got several listener comments on PETA, Martian food, and space nutrition.  In fact Doug called to say that he thought early Mars missions would likely be vegetarian just for mass and technical reasons.  Our last caller was Perri who wanted to talk about the need to refurbish and bring back to life the excellent Colorado teaching planetarium, the Robert H. Johnson Planetarium in Jefferson County.  Perri provided us with lots of good information on this planetarium and its refurbishment needs.  She also talked about food consolidation problems in the U.S. and globally, plus a host of other matters, including the plutonium issue which was mentioned in the first segment.  Here, she told us about the Rocky Flats Cold War Museum based on The Rocky Flats Nuclear Plant.  The museum is also in Jefferson County, CO. For more information, visit www.rockyflatscoldwarmuseum.org.  If you want to connect with Perri about the planetarium or any of the other issues she mentioned, you can email her through me.

     You can also email all our callers through me at drspace@thespaceshow.com.  Please post your comments/questions on The Space Show blog.

Guests: Dr. Richard Obousy, Dr. Eric Davis, Dr. Harold Sonny White.  Topics:  Faster Than Light (FTL) Travel, Warp Drive, Interstellar Travel. Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://thespaceshow.wordpress.com. Comments and questions should be relevant to the specific Space Show program.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information.  We welcomed our three guests, Drs. Obousy, Davis, and White to the program to discuss FTL travel, warp drive, and interstellar flight.  More information is available at the Icarus Interstellar website, http://www.icarusinterstellar.org.  We did not take a break during our program.  Also, at times our discussion was technical and scientific. I looked up many terms & used my search engine frequently during the discussion given the advanced nature of the subject and our discussion.  Don’t be shy about looking up that which you may not understand or know about. I promise, if you do it will be well worth your time.  We started with an introduction to Icarus Interstellar, FTL travel, and why interstellar propulsion & travel is important.  Our guests then suggested the two most common approaches to FTL travel included warp drive and worm holes.  For most of the program, we focused on the characteristics and research around warp drive.  Our guests explained their research, including how they were able to develop the theories that reduced the amount of energy needed for warp drive from Jupiter size energy requirements to energy requirements representing the approximate mass of Voyager 1.  Our discussion addressed the Miguel Alcubierre warp drive in light of the advanced work by Dr. White and others.  The concept of the McMonigal Fatal Flaw was addressed with our guests explaining why it was not applicable.  The workings of the warp drive were explained and though the discussion was heavy in physics, I urge you to take the time and embrace & learn about the advanced theoretical physics subjects discussed by our guests.  Later, a listener asked about the use of a sun gravitational lens telescope at a specific AU from the sun as perhaps an alternative to interstellar flight.  As you will hear, such a device would likely be a good tool enhancing FTL travel, not replacing it.  As our discussion progressed, or guests rebutted many of the warp drive criticisms. Near the end of the program, we talked about what was needed to go from the lab and theory to small scale demo experiments to prove out the concepts.  Our guests referenced to the Chicago Pile-1(CP-1) 1942 nuclear experiment & the subsequent step by step evolution of nuclear technology.  Our guests talked about starting small with a demo proof and evolving upwards with more and more discovery, technology, and engineering.  Another example cited for the typical development path included the discovery of the electron in 1897 followed by the discovery of the proton in 1917, and the discovery of the neutron in 1932. Throughout our discussion, our guests put forth compelling reasons why we should be developing FTL travel and interstellar spaceflight.  Their respective concluding comments reinforced the importance and why of our being interested in FTL and exotic concepts.

Please post your comments/questions on The Space Show blog per above.  If you want to email our guests, you can do so through me.

Guests:  Tabitha Smith, Gwyn Rosaire.  Topics:  Nuclear propulsion, Project Bifrost, Icarus Interstellar.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://thespaceshow.wordpress.com. Comments and questions should be relevant to the specific Space Show program.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information. We welcomed Tabitha Smith and Gwyn Rosaire to our program to discuss Project Bifrost and nuclear space propulsion.  For more information and to contact our guests, visit www.icarusinterstellar.org/projects/project-bifrost. If you are interested in joining Project Bifrost, or have suggestions, please use the “here” email link on the webpage. During our first segment, Ms. Smith started by giving us the origin and meaning of the project name, Bifrost (pronounced BEEFROST).  This discussion included Icarus Interstellar and mention of the Darpa 100 Year Starship Program (100YSS).  I asked Gwyn about our technical status in having a nuclear thermal rocket and he said we had more of an economic problem with nuclear propulsion than a technical problems.  We talked about the lack of a mission for a nuclear rocket and that such a mission would be generated from the White House on down.  Nuclear fuel was a topic as new research is focusing on tungsten fuels rather than graphite though our caller Dr. Jim Dewar suggested new opportunities existed with modern graphite fuels.  Other listeners emailed in both questions and comments about fuel.  Another topic included a discussion about a much larger payload to Mars with a nuclear thermal rocket (NTR) than a chemical rocket so I asked our guests about economic trades as to what would eventually be less costly, multiple chemical rocket launches or the use of a NTR.  Using the Saturn V for our chemical rocket, We carried our analysis to the point of including additional launches to cover for a launch failure and also the human factors side in that a shorter trip means less radiation for the astronauts, thus less shielding and potentially less mass.  I think you will find this discussion and analysis most interesting, including the NRC equation for astronaut exposure to radiation. In Dr. Dewar’s call, he also talked about the B4 core concept & the progress made with NERVA.  We got emails from Bruce in Canada plus other listeners advocating private sector development, a change in ITAR, and the radiation policy changing after Fukushima per this article, www.world-nuclear-news.org/RS_UN_approves_radiation_advice_1012121.html, and the UN Scientific Committee on the Effects of Atomic Radiation (UNSCEAR).

In our second segment, Michael called in to ask about Russian outreach and the Russian nuclear propulsion program.  We then asked our guests for the future Project Bifrost plans.  We learned of several major issues.  One issue centered on U.S. export control. Our guests also noted that the Russian economy was actually gaining in strength and this might cause them to think its better to go it alone than team up with a weak international partner.  Other listener emails inquired about time lines for operation.  It was suggested that about ten years would be needed for the NTR if all goes well.  As for more routine Mars flights, it was suggested that it would take about twenty years after the first human flights to Mars to really have the program operational. We talked about the private sector and our guests suggested that the private sector will play a strong role in developing and using nuclear propulsion.  Moving on, the second project our guests mentioned had to do with ablation technology using NASA Ames facilities.  The third and final project mentioned was at Huntsville, the Decade Module 2 fusion project at Marshall.  During both the first & second segments, our guests talked about Jupiter radiation and magnetic shielding. John asked about this when he called in the second segment.  Doug inquired about Dr. Zubrin’s Mars plans & possible trajectories that could be used with the pros and cons for each. Bruce inquired about fuel vibration problems, then Tim called wanting to know about tours at the Marshall facility & the level of power needed for interstellar travel.  As we were ending, our guests said we needed breakthrough propulsion or new physics for interstellar travel. Both our guests left us with important closing comments relevant to Project Bifrost & nuclear propulsion for our future with space development.  Don’t miss what each had to say as we brought our discussion to a close.
