Dr. Jon Clark was the guest for this Space Show program. This show covers many issues and aspects of human factors for space, ranging from sport diving from high altitude or even space to the more common discussion topics of air sickness. We discussed the forces that one encounters when making this type of jump, we talked about the equipment needed, we compared it to SCUBA, and much more. Scattered throughout the program we discussed crew safety, ejection from a disabled spacecraft, and much more. Dr. Clark was asked many questions about suborbital space flight, centrifuge training, even airsickness and vomiting. Listen to his responses. We also talked about health screening needs, how medicines work or don't work in space and what type of R&D is being conducted to improve our understanding of pharmaceuticals in space. We also talked about the accident history in space and Dr. Clark noted that progress and evolution comes at a high expense, in blood, and we saw this again yesterday in Mojave. We talked about learning lessons from our mistakes and past history. Later in the program, space suits were discussed in some detail. We also went into detail about the National Space Biomedical Research Institute (NSBRI) and its work, including work available to the public at their website, www.nsbri.org. Here, you can find the contact information for Dr. Clark and an enormous amount of educational material on the subjects discussed today plus on the entire field of human factors for space travel. I urge you to visit this site and learn about NSBRI. Dr. Clark has also prepared a superb 5 mb Power Point presentation titled "Crew Survivability in Human Space Flight: Past, Present, and Future." I have permission to send this file to listeners by email but remember, its a 5 mb file so make sure your email account can receive it before requesting it. If you would like this presentation by Dr. Clark, please send your request with a valid email address and I will send it to you. This was a comprehensive two hour discussion with Dr. Clark on a wide ranging list of subjects, topics, and items of importance and interest for human space flight. Again, this is a must listen to show. You can communicate your comments and questions to Dr. Clark through the NSBRI website information or of course through me at drspace@thespaceshow.com.
