John Batchelor and I welcomed Dr. Jim Logan for a double length session focusing on the new study that appeared in Nature, "Apollo Lunar Astronauts Show Higher Cardiovascular Disease (CDV) Mortality: Possible Deep Space Radiation Effects on the Vascular Endothelium."  Dr. Logan said this was a seminal study because of the control groups used which were astronauts in the nonflying category as well as the orbital flying category and about half of those that walked on the Moon. I urge you read the full study which can be found at www.nature.com/articles/srep29901.  He talked about this being the only study ever of its kind, the significance of the samples even though the sample sizes were small, and the serious questions raised for long duration BLEO human spaceflight.  He discussed radiation levels, the results of the instrument readings on Mars journey and surface radiation from the Mars Science Lab and Curiosity, & how to understand the data from the study and what it means.  We talked about possible mitigation strategies and CVD treatments and risks for inflight disease development.
