We welcomed back Dr. Michael Schmidt for updates and more information regarding Personal Spaceflight Medicine. Note that the abstract referenced in the second segment has been uploaded to the blog for this show.  During the first segment of our 92 minute program, Dr. Schmidt defined personal spaceflight medicine for us & talked about targeting individuals for specific countermeasures to human factors risks for longer duration spaceflight safety.  We talked about artificial gravity and radiation with our listeners asking questions about both fields.  Our guest cited several examples to make his point.  At one point he talked about the current twin study underway on the year long plus ISS experiment with a Russian cosmonaut as well.  Questions were asked about using pharmaceuticals in space, how they might react with different people, and the distribution methods so far which are not great.  At one point, Dr. Doug emailed in asking about the use of omics for space travel issues and if in fact the use of omics would reveal even more questions that cannot be answered, ultimately delaying long duration HSF missions even longer than they are delayed now.  Don’t miss the guest response to Doug’s question.  Kris emailed in asking about the use of deliberate hypothermia to store Mars bound astronauts, and then another Doug question came in about selecting the best people based on omics for a mission.  Near the end of the segment, I asked our guest if he had done work for Mars One. He explained their limited capacity relationship which I assume ended.

In the second segment, BJohn asked about the possibility of astronauts sleeping in a small vertical centrifuge.  Dr. Rowe called to talk about the issue relating to pharmaceutical use in space.  he talked about delivery methods, malabsorption, etc.  Later, Dr. Schmidt brought up the damage done from sleep deprivation and showed how this is a potential problem for space missions.  Doug emailed in a question about GCRs and radiation, then Dr. Schmidt talked about his new paper on BDNF with his associate Dr. thomas Goodwin, “Protecting Neural Structures and Cognitive Function During Prolonged Space Flight by Targeting The Brain Derived Neurotrophic Factor Molecular Network.”  We talked about BDNF and spaceflight, exercises, mitigation measures, and more. He referenced Mars simulation, behavioral issues and more. You don’t want to miss this discussion.  Dr. Schmidt provided us with excellent closing remarks.

Please post  your comments/questions on TSS blog above.  You can reach Dr. Schmidt through me.

Also mentioned on the show were a couple interesting sounding shows about psychological problems reported in Russian cosmonauts on Mir. Worth listening to!


2. J Fincannon - June 2, 2015

What I would have liked to have asked was whether there was any way to assure that two separate biota (terrestrial and a potential Martian) can be guaranteed to remain separate. There is so much talk that we are going to send humans to Mars, but we have not yet ruled out existing Martian life forms, we seem to have few instruments to look for them. How different do they have to be to remain separate? Can humans life without their biota? Is there any possible filter to keep the biota from travelling either way?
