During our 71 minute discussion, Dr. Robinson provided us with an overview of science on the ISS, specifically identifying two goals: 1: Research for BLEO; 2: Developing LEO for long term space use and for benefiting life here on Earth. We discussed the logistics of science on the ISS, the ISS international partnership and how ISS resources are allocated to the partners for science as well as other projects. Our guest further broke this down between Russian and the U.S. and then said that for the U.S. segment, the U.S. has about a 76% usage allocation of ISS resources. We talked about the science done on the ISS, the mix with government and commercial projects, then we started talking about the 1 year study with the Russian cosmonaut and American astronaut while at the same time doing the Twin Study with astronaut Scott Kelly on the ISS with his brother Mark Kelly here on the ground. Dr. Robinson spent much of the balance of our interview time going into the specifics of these concurrent studies, the investigation categories for each study, and more. Our guest fielded questions about the length of time for the study being fixed at one year rather than being longer and objective oriented. As you will hear, ISS logistics, using the Soyuz as a lifeboat, and the overall ISS operations and other experiments going on all contribute to why a one year study was settled on rather than a long duration study or one based on achieving certain accomplishments or objectives. Dr. Robinson talked about the possibility of future studies given that they anticipate issues and information from this first study suggesting more refined studies to be undertaken in the future. Listeners emailed our guest several questions including asking her about the assumed low science productivity on the ISS, a statement Dr. Robinson refuted with evidence. BJohn also asked about low gravity issues. Later, in a follow up question, BJohn asked about a Phobos mission and doing human spaceflight mission simulations on the station. Don't miss Dr. Robinson's response to these questions. Dr. Bill Rowe called to talk to her about CO2 buildup, oxidative stress, EVAs, and possible magnesium deficiencies in astronauts while in space. We talked radiation issues, the OSHA rules for maxing out on radiation, and finding astronauts for the long mission that would not be disqualified due to the OSHA radiation rules. Vision problems, fluid shifts and other complications were discussed throughout our interview with Dr. Robinson. A listener commented that both participants in the 1 year study were men and wanted to know about gender differences which Dr. Robinson addressed. Another listener wanted to know about shared access of the information and if it would be made available to the commercial industry, the space tourism industry, even Mars One as an example. Later in the segment, Dr. Robinson went into much more detail regarding the investigation categories for both the 1 year and the Twin Study. When talking about fluid shifts, she was asked about differences in the Russian approach as compared to the American approach. One example that she provided us was the Russian use of their Chibis suit which sucks fluid back down to the legs. In making additional points in reference to space settlement questions, Dr. Robinson talked about comparisons with space to early oceanic exploration and said that people are not living at sea for their entire life even today. Don't miss this discussion. Based on other questions, the human gravity RX was discussed along with the use and challenges regarding centrifuges in space, alternative propulsion to get to a destination much quicker, and the fact that even a low gravity body is better for people than no gravity. Again, don't miss the discussion. We talked more about behavioral studies, Dr. Doug asked a series of three questions that took us through to the end of our program with other listeners asking questions in-between Doug's. For example, cognitive issues came up as did timelines and influences to making rapid research progress including money and financing. As we were about to end, I did ask about genetic screening, experimentation, and modification. Don't miss what our guest had to say about this and why. As we were ending, I inquired about research plans once the ISS was deorbited. Again, don't miss the options that were discussed with us. Dr. Robinson left us with thoughtful concluding comments you will want to hear, plus she provided us with the social media contact information to follow ISS research on a regular basis.
