We welcomed Anthony Young to the program to discuss his book “The Saturn V F-1 Engine: Powering Apollo into History. This is an excellent book which I strongly recommend. Remember, if you buy it through the OGLF Amazon portal, Amazon makes a contribution to The Space Show. During the first segment of our two hour program, Mr. Young started out talking about the book and why he wrote it. Since our guest had also written books car engines, I asked him if there were comparisons to be made with the F-1 & the large, complex, & powerful car engines. We also talked about potential plans to rebuild and modernize the F-1 for either the SLS or as a possible engine replacement for the Air Force RD-180. Anthony did say that it would not be a rebuild of the F-1 but a complete remake of it with modern manufacturing, materials, etc. Another topic discussed was the F-1 thrust for a new engine. Marshall called to talk about fuel propellants for the F-1 and air pollution. This gave Anthony the opportunity to talk about ATK and their efforts to modernize the SRB & solid rocket propellant. Anthony suggested that we need advanced propulsion for humans to Mars to significantly reduce the transit time, not a new F-1. Michael called in & talked about SLS being needed to preserve the expertise & knowhow for making large rockets & flying them. He also spoke about some of his upcoming Space Review articles on the Code of Conduct & other subjects. He brought to our attention a YouTube video, “The Engines That Came Out Of The Cold” (www.youtube.com/watch?v=MZnYr94aa9E). Mr. Young was asked about the existence of NASA lunar programs. He mentioned several including Lunar CATALYST but suggested they were small robotic missions. He did not think there were NASA human flights planed for the Moon. Dwayne called to shed further light on NASA and lunar programs. He also spoke about the F-1 thrust for a new engine.
In the second segment, John called from Ft. Worth. He spoke about technology and performance for the engine, other programs now cancelled & the logic of having stayed the course. He brought up good points on our losing our technology capability, then Anthony addressed many of the NASA KSC infrastructure changes going on to partner with the commercial industry. Doug called to talk about some of the lunar program comments, to offer a different perspective on SLS, & public/private partnerships as well as international participation. Anthony was asked for his thoughts on where our space program might be today had the Saturn V & F-1 not been cancelled. In responding to this, he talked about how complex the F-1 was & how many parts were in it.

Guests: Tabitha Smith, Gwyn Rosaire. Topics: Nuclear propulsion, Project Bifrost, Icarus Interstellar.

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 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.
