Here at the south pole, we get lots of visitors – and many of them are extremely interesting. This past week I had the honor of meeting NASA Astronaut Scott E. Parazynski, MD. Dr. Parazynzki is now working as the Medical Director of the United States Antarctic Program. Having dinner with both Dr. Parazynzki as well as Dr. Sean Roden, former International Space Station Lead Flight Surgeon and now South Pole Chief MD was extremely interesting. Among other things, we discussed the various missions that Dr. Parazynzki and Dr. Roden had worked together on, as well as a few of the more interesting logistics for Antarctic medicine.
