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 Sir Martin Rees to discuss his chapter in the new book Starship Century: Toward the Grandest Horizon, edited by James & Gregory Benford.  Sir Martin’s chapter, titled “To the Ends of the Universe,” looks forward through time and centuries to address human spaceflight, eventual interstellar travel, life extension & more.  In looking forward, he levies criticism on the past. We talked about several of his comments regarding our past & current space program. Dr. Rees mentioned the need for life extension though for Mars he said we could do that without life extension but we should not fool ourselves as it will prove far less comfortable than Mt. Everest or the South Pole.  We talked about finding planets & the possibilities for life, then we switched to the discovery of quasars soon to celebrate its 50th anniversary. Listeners asked our guest about his comments that the political impetus for current & future space work seems to have been lost, especially in contrast to the Apollo era.  In his response, our guest suggested we need low cost and reusable launch vehicles given how costly everything is today.  He commented that mining asteroids did not make sense other than for ISRU purposes. Before going to break, he was asked about the UK government investment in Skylon which he supported.

In the second segment, we spoke about changes in the UK space activity over the past decade.  Sir Martin made comparisons with the UK, ESA & NASA, especially regarding long term planning & our very short one year budgets.  He suggested our budget process makes us unreliable partners in many respects.  Quasars were again a discussion topic, plus Sir Martin fielded a question from a high school student wanting to know how we know the laws of physics are the same throughout the universe.  Another listener wanted to know about science fiction as a leading indicator for science.  Dr. Rees suggested some excellent books for those interested in reading specific science fiction works. James Benford, editor Starship Century called to point out the excellent reading list in the back of the book, plus he offered us important comments about the book & authors. Near the end, Sir Martin was asked to look forward 10-15 years & tell us his thoughts.  His response focused on finding even more planets around the stars, identifying more threatening NEOs, & even more attention given to life extension issues.  The last two questions asked our guest dealt with the ISS living beyond 2020 asking if that was valuable and also the recent podcast by Dr. Neil deGrasse Tyson that SpaceX would not be able to go to Mars.  Throughout the discussion, he mentioned the private sector doing things government could not, especially due to less risk averseness.
