We welcomed back Dr. Madhu Thangavelu to discuss current graduate student design projects from his most recent USC class which had a theme dealing with NEOs and mitigation strategies.  During the first segment of this 1 hour 41 minute show, Dr. Thangavelu focused on the future of the ISS, lunar exploration and settlements, a bit on Mars but mostly on NEO issue and surveillance of dangerous items.  He summarized several of the student projects for us including one referred to as “Trojan” asteroids and another referred to as “space rocks to take care of rocks.”  Also in this segment we talked about nuclear rocket technology and propulsion, asteroid mining, and Directed Energy devices.  For the latter, we spoke about the ease of using the technology as a space weapon.  Toward the end of the segment we discussed how to enroll in Madhu ‘s class, especially if you are not a USC graduate engineering student.  Our guest summarized the segment saying that planetary defense will happen and his class helps to train and condition creative minds to deal with the problems.

In the second segment, Professor Thangavelu received a listener question about Earthship Houses and the Cal-Earth Institute.  Madhu also spoke about the recent NASA NIAC Conference held at Stanford University.  Regarding the conference, he spoke about many of the keynote addresses and speakers, plus extremely innovative projects.  One such project was Contour Crafting which he said was now in Phase 2 (see www.contourcrafting.org).  Another listener went into more detail with him on the USC application process to attend his class, then Madhu went back to sharing more with us regarding the NASA conference.  He said keynote speakers were from MythBusters, Google, SETI, SSI, and Dr. Pete Worden of NASA Ames.  Later in this segment, he talked about the space business model with Elon Musk, Stratolaunch, and more.  He fielded a few specific questions on asteroid mining which he did not think was ripe for investor action at this time.  He was asked about green technologies & the student design projects, then about his upcoming article in the Journal of Space Philosophy.  One of the last topics was the introduction to us of co-robotics, suggesting we check it out at the National Robotics Initiative ( Google co-robotics for more information).

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.  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 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.

Contact Dr. Livingston for questions about our copyright and trademark policies.  We welcomed back Dr. Madhu Thangavelu and our new guest, Perry Edmundson to discuss the Cosmic Mariner space cruise ship concept which Perry developed while a graduate student in Dr. Thangavelu’ s Space Exploration Architectures Concept Synthesis Studio.  You can find Perry’s slides and his presentation paper on The Space Show blog.  Our first segment of this nearly two hour discussion covered the basics of the USC class taught by Dr. Thangavelu, including prerequisites and needed student background.  Madhu talked about class objectives & goals along with explaining his methodology in teaching the class.  We then switched over to Perry who began explaining the Cosmic Mariner concept.  If you follow along with his slide presentation which is on the blog, you will see terrific illustrations plus his comments will be supplemented by important visuals.  Perry explained the concept, talked about his design incorporating inflatable modules, the three main elements of style he incorporated in his design, the role of the ISS, and why he decided to make use of the ISS.  As for challenges to bringing the concept to reality, he talked about radiation issues along with other human factors issues.  One issue he zeroed in on dealt with the psychological issues faced by crews on longer missions.  Life support was discussed along with the need for far more powerful propulsion such as nuclear electric propulsion.  Perry spent some time discussing nuclear propulsion and related issues.  Madhu brought up the benefits of using hosted payloads & both our guests talked about SpaceX & its progress toward human spaceflight.
     In our second segment, Perry talked about bandwidth issues and urged the use of optical transmission as a solution path.  Trent asked about the NASA Gateway Program & we talked about using his cruise ship concept to go to Mars.  Perry explained what some of the modifications would have to include to make his concept viable for Mars.  Again, he stressed the human factors challenges.  John from NJ called in to talk about funding issues & challenges.  He also asked why the ISS was being used given it may meet its end in a few more years.  Perry suggested that his concept would provide a new purpose for the ISS.  We talked about the development of new technology for problem solving & were introduced to the concept of “technology evaporation.”
