We welcomed back Dr. Madhu Thangavelu for a 1 hour 45 minute discussion on a wide ranging set of topics from space visionary concepts to HSF to Mars, radiation and other issues, fantasy vs. reality thinking, and the synthetic mind. Madhu provided us with these links relevant to our discussion: 1. AIAA talk slides:
https://info.aiaa.org/Regions/Western/LA/Lists/Presentations/DispForm.aspx?ID=6 ; 2. AIAA Space Architecture panel video on YouTube : www.youtube.com/watch?v=ig3FzB0bQnA, 3. USC Space Concepts Studio website : http://denecs.usc.edu/hosted/ASTE/527_20111, 4. latest USC Eng. magazine carries an article, p16-17: http://viterbistorage.usc.edu/Public/USCVITERBIMAG.pdf. In our first segment, Madhu opened up by talking about students and space inspiration. Based on his own USC teaching experience, he said students were fired up. Our guest was asked to compare robotic missions to HSF missions and Madhu spent some time on this discussion. He also talked about the NASA plan to capture an asteroid, referring to this as a possible wild goose chase. He talked about the ISS and using it more and more to accomplish important space goal. Madhu received several questions about Tito’s Inspiration Mars flyby mission. Here, he had much to say, especially about radiation, deep space communications, food & nutrition, and even physiology degradation. We talked about using nuclear propulsion for such a mission & he suggested a better mission profile using two Falcon rockets.
In the second segment, Paul asked about using nuclear electric propulsion as compared to the two Falcon rocket idea. Madhu talked about the nuclear propulsion history with NERVA & the use of nuclear fuel on many of our robotic missions. Michael called in and said there was no real political will for nuclear so it probably would not happen anytime soon. Later, Madhu was asked many specific radiation questions regarding the Mars flight. Madhu suggested possible mitigation strategies, including his favorite, self cellular repair. Allison emailed in to inquire about his Studio students and how he holds the line from reality thinking as compared to Kool Aid thinking. Madhu talked extensively about this issue, discussed the philosophy of idea generation, visionary thinking with some fantasy while at the same time being grounded in engineering, physics, financial and other subcomponents of the concept. Don’t miss this important discussion. We also talked about disruptive technologies. At the end, we talked about the synthetic mind.
Please post your comments/questions on The Space Show blog above. You can contact Madhu through me.

Guests: Dr. Madhu Thangavelu, Jake Dodd. Topics: This program discusses Jake’s concept of placing a nuclear fuel plant in space in support of nuclear propulsion/space needs.

We welcomed back Dr. Madhu Thangalevu and his student Jake Dodd to discuss the concept of SNAP-X: The Space Nuclear Activation Plant. I have uploaded his AIAA paper by the same title and his Power Point slide presentation to The Space Show blog which should provide you with more specific information about Jake’s concept. Essentially, the plan calls for putting a breeder reactor in space to supply nuclear fuel for space needs safely rather than launching from Earth all the time. During our first segment, both Professor Thangavelu and Mr. Dodd explained the concept in detail. We talked about weapons proliferation in the process, the breeder reactor and why that was the chosen technology, the safety in place for this technology, and the use of it in the EML1 location and why. Part of our conversation focused in on projected time lines and development costs as I tried to get an idea of what would be involved in bringing this project to at least an Earth-based demo status. Listeners emailed and called in about the problems given the amount of fear within the public and parts of the government every time the word nuclear is mentioned, then saying that the use of a breeder reactor heightens that societal fear level. We discussed ways of dealing with this during our discussion. In addition, listeners questioned the safety of a breeder reactor and the use of Thorium as a non-weapon nuclear fuel.
In our second segment, we talked more about tight budgets, private and public partnerships, and international cooperation to bring this project to at least demo status. Charles called in to challenge our guests on their Thorium comments regarding conversion to U-233 which he said was an effective fuel for weapons as was U-235. I believe you will find this exchange most useful in understanding many of the issues regarding this project. Our guests brought up the nuclear rocket history and the NERVA project, plus we asked Jake for his plan of attack in getting his project going. As our program was ending, Madhu talked about his next Design Studio Class which culminates with new student projects on Dec. 18th.
I look forward to talking about many of these projects on The Space Show in 2013. Post your comments/questions on The Space Show blog. If you want to email either of our guests, please do so through me.
Here are the two documents we talked about during the show regarding Jake’s concept.
