Welcome to this 1 hour 53 minute program focused on auditions for possible new Space Show guests plus Open Lines calls from listeners.  While there were no audition calls, two callers checked in to talk about nuclear propulsion, reactors, fuels, ISP, etc.  Both calls were interesting and instructive.  I also promoted the upcoming Next Giant Leap Conference in Hawaii from Nov. 9-13.  For more information about this conference, visit http://2014giantleap.aerospacehawaii.info.  During the first segment, I went over the audition ground rules for the show and discussed the best way for self-invited guests to be on The Space Show.  The best way is to call an Open Lines program and let us know what you have to say and why you believe you should be on the program as a guest.  Long time Space Show guest and caller Dave Ketchledge called to talk about nuclear rockets and reactors.  We covered lots of information including what it takes to actually turn on and start up a nuclear reactor.  We talked core issues & I inquired about the possibility of a gas core.  Dave talked about new and exotic nuclear fuels, the nuclear waste problem, including how the waste is treated by the advanced design Westinghouse and GE reactors plus those in France.  I asked Dave for his thoughts on the timeline for a nuclear rocket. He said probably 20 years but were we to have leadership in the area and funding, perhaps as early as ten years.  Toward the end of his call, he shared with us a few horror stories where nuclear workers had done really stupid things.

In the second segment, again there were no audition callers so I talked about how to be a Space Show guest, especially if you are self-inviting yourself to the show.  As I said before, the best way to do it is to call an Open Lines show or come in recommended by a previous guest or somebody I know.  I also spoke about listener participation through emails and phone calls with live shows rather than emailing me complaints about the program or guest after listening to the live show.  The bottom line is that we want your feedback and exchange with the guests, not after the fact.  SLS John called to talk about the Classroom show from Sunday, specifically the nuclear component of the discussion revolving around the Aquarius project proposed by Dr. Jim Logan and Dan Adamo.  John was again questioning the 900 seconds of ISP with water as the fuel.  I suggested he post his comments on the blog for that show as I was not the one to respond since Aquarius was not my project.  I did ask John to explain some basics about nuclear rockets, especially the part about the dissociation of the hydrogen atom.  We went over T/M, chemical fuel bonding, molecular weight and what happens with the very high temperatures involved in the nuclear rocket.  I also asked John for his background in the subject and for his bio as he is part of the Great SLS Webinar Debate upcoming on The Space Show on Sunday, Nov. 16 with Rick Boozer.  Finally, during this segment I highlighted some of the upcoming Space Show programs on the schedule.

Please post comments/questions on The Space Show blog.  You can reach either of our callers through me.

Dr. Erik Seedhouse, Sunday, 9-30-12


Guest:  Dr. Erik Seedhouse.  Topics: Ocean outposts, living underwater, and the oceans as an analog to space.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, https://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. Dr. Erik Seedhouse returned to discuss his book “Outpost: The Future of Humans Living Underwater.  If you buy the book from Amazon with this URL, Amazon will contribute to The Space Show: www.amazon.com/Ocean-Outpost-Underwater-Springer-Popular/dp/1441963561/ref=onegiantlea20. In our first segment, Dr. Seedhouse introduced us to the subject of living underwater.  We discussed some of the basics per the outline suggested by the contents in his book.  You can see the book’s contents at www.amazon.com/Ocean-Outpost-Underwater-Springer-Popular/dp/1441963561/ref=onegiantlea20#reader_1441963561. Follow along for the general topic discussion. He received questions about comparing living underwater to living in space or perhaps on the Moon or Mars.  I asked our guest about human factors issues such as those experienced in long duration spaceflight.  Dr. Seedhouse talked about bone necrosis with the saturation divers.  Other issues in this segment dealt with scuba as a pre-requisite for spaceflight training, the recent deep dive in a small submarine by James Cameron, and the amount of money spent on ocean habitat R&D compared to that being spent in space.
      In our second segment, we went into detail on many of the topics in his book including biochemical decompression, liquid breathing, vasculoid, and artificial gills.  We compared space suits to dive suits, specifically the ADS2000 hard suit.  Several listeners called in asking about time lines for operational ocean outposts and habitats as well as many of the advanced technologies Dr. Seedhouse was telling us about.  Near the end of the program, our guest went into more detail about budgets for developing the capacity to live underwater as compared to the NASA budget and what the private space sector is now doing.  Erik also compared the amount of press, media , & PR given to space matters as related to ocean matters.
