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/r.... 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. If you have comments/questions, please post them on The Space Show blog above.
