Dr. Jay Buckey was the guest for this Space Show program, discussing space medicine issues and some insights into NASA psychological issues given the current news events with a NASA astronaut. We opened the program with the discussion psychological screening, could it be done more effectively and more routinely, especially given the fact we learned such screening or analysis is only given an astronaut when the candidate is selecting into the program. This is a discussion you will want to hear. We then talked about space medicine issues, specifically as they pertain to long term space flight. Here we also discussed psychological issues but also Dr. Buckey examined radiation and the issues surrounding it for the longer duration flights and programs. He suggested active shielding with magnetic fields will probably be better than passive shielding though much work needs to be done to create it and make it work. A listener asked about artificial gravity and Dr. Buckey agreed that it was important but explained to us the engineering and other trade offs with it. Other issues and topics we discussed included likely future advancements in medicine and technology, prescription drugs in space, and the National Space Biomedical Research Institute (NSBRI) and some of the projects Dr. Buckey work with as a Team Leader for NSBRI projects. Here we talked about commercial application to some of the research including detecting and sizing bubbles in the blood to prevent decompression sickness and other problems, lunar and Martian dust issues to protect the lungs, and more. Listeners should visit www.nsbri.org for more information about this organization and its work. Dr. Buckey's book, "Space Physiology," is widely available and suggested to listeners who want to know more about these and other issues. Listeners can also read his article in Dartmouth Medicine, "Taking a long view." Check it out at http://dartmed.dartmouth.edu/summer06/print/grand_rounds.php. You can send your questions or comments to Dr. Buckey through me at drspace@thespaceshow.com and I will promptly forward them to him.
