We welcomed Dr. Julie Robinson, ISS Chief Scientist, to the program. 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.

We welcomed Dr. Kim Binsted and Simon Engler to the show to discuss the Hawaiian Space Exploration Analog and Simulation (HI-SEAS) project.  During the first segment of our 90 minute show, Dr. Binsted and Simon introduced us to the HI-SEAS project, described its ideal location in Hawaii, and the physical site itself.  Simon was on the first mission which was a four month simulation.  He described the simulation, his experiences and perspectives throughout our discussion.  Kim also described her FMARS at Devon Island experiences in this segment.  We learned that for the HI-SEAS projects, the first focus was on food and the food system which they explained in detail.   Crew dynamics were discussed  plus our guests took us through the crew screening process.  Also talked about were crew issues, conflict resolution and crew leadership.   I asked about the relevance of analog research to a real Mars mission then our guests brought up the need to retire risks, especially team risks.  Mars One came up as did a listener question asking if the Mars simulation was applicable to the Moon.  Another listener asked how talking about HI-SEAS and Mars simulation went over with the non-space community and did they think humans to Mars was important.  Hawaii as a space state was discussed along with issues based on possible conflicts with sacred Hawaiian culture.   More questions came in about the food used for the simulations, the crew cooking, and resupply.

In the second segment, we talked about opportunistic research plus comparisons of HI-SEAS to Biosphere.  I inquired about their using submarines as models which they did in their basic habitat research plus Kim shared with us a prison story as a prison can also be a model for habitat simulations.  Judy asked a question about spiritual life and connections while on the habitat and the simulation.  Note how our guests responded to this question.  We talked about the crew EVA missions, spacesuits, and possible gender differences on the missions.  Doug sent in a note about crew cohesion, the possibility of a single gender crew, and issues of flirting, jealousy, etc.  Don’t miss both Kim’s and Simon’s discussion on this subject.  Simon did say he thought the relationships were like brother-sister on his simulation.  Crew medical concerns and issues came up as did the habitat systems and the crew developing their own strategies and protocols for dealing with issues.  Todd inquired about an exercise routine similar to what might be done on a Mars mission, then Doug emailed again about life support issues & recycling for the simulation.

We welcomed Dr. Mark Shelhamer, Chief Scientist of the NASA Human Research Program to the show to discuss the critical risks associated with BLEO long duration HSP. You can hear his FISO talk on this topic from April 2, 2014 at http://spirit.as.utexas.edu/~fiso/telecon/Shelhamer_4-2-14/Shelhamer.mp3.  His associated Power Point can be downloaded at http://spirit.as.utexas.edu/~fiso/telecon/Shelhamer_4-2-14/Shelhamer_4-2-14.ppt.  During the first segment of our 95 minute discussion, Dr. Shelhamer started off saying  we would be talking about beyond low earth orbit only and that many of the risks are unknown since we have very little experience with BLEO.  Much of what we do know is extrapolated from our current knowledge base plus our Apollo experience.  Next, our guest defined three major areas/issues.  First he listed medical issues which he later described as onsite medical treatments for various complications, illnesses, surgical needs and such.  He classified physical deconditioning issues such as muscle and bone loss issues, cardio vascular issues in a different category.  The second group he identified had to do with radiation, and the third group included psychological-social issues.  I asked about Microgravity not being in the top three and he said because those issues are likely a constant for both LEO and BLEO missions.  He then talked at length about the challenges needing countermeasures/mitigation.  He did not say these were showstopper challenges but they do require effective countermeasures.  For example, he said humans could probably survive a trip to Mars today providing the hardware & life support was up to the job but their goal is to get the crew there in good condition, to be able to do effective work, and to return safely.  He did not think those goals could be obtained today.  I asked if money was a primary issue and it was not though he said more money is always helpful. He talked about the time needed for some human studies, team studies, and research, sometimes extending even longer than a year.  He then took us through the three categories to tell us what NASA was doing & how it was doing in that research area. You might be surprised by what you hear.  I certainly was.  Later, we talked about ocular/vision issues which are now getting front page attention.  He explained the latest theory causing the problem as possible fluid shifts.  Listen to this discussion.  Note that once we start with BLEO HSF, we may find other problems that do not now show up now.  Also, we may develop a countermeasure for one problem but that opens the door to lots of other problems currently unknown.  One tool he talked about that was being tested on the ISS Russian sector was lower body negative pressure.  Artificial gravity was a big part of our discussion.  While everyone is enthusiastic about it, he made the point of saying we don’t know the needed spin rate nor do we know what level of gravity is needed for humans or for how long. Just spinning a spacecraft without knowing this information is unlikely to be successful let alone cost effective or economic. He also pointed out that artificial gravity is costly, requires lots of energy, a huge spacecraft which means lots of mass to orbit, & to do it, it needs to be done in a way that maximizes the benefits for the crew.  Without knowing the precise spin rate and gravity needs for humans plus how long the crew needs to be in artificial gravity, it is likely it won’t be done just for cost and economic reasons alone.  Charles emailed in about bed rest analog studies.  Joe sent in a question about lower back pain & spine issues.  As the segment ended, I asked him if humans were lousy candidates for BLEO spaceflight.  Don’t miss his answer.

In the second segment, we took a call from Dave about nuclear submarines as an analog for HSF studies.  Our next topic was space radiation which our guest discussed in detail.  I then took two email questions from B John in Sweden.  He asked about the benefits of microgravity for disabled folks, then I read a longer email from him suggesting solutions for the microgravity, psychology, and radiation issues already existed and why was NASA not proposing and developing “these simple non-medical solutions to the problems you describe.”  Dr. Shelhamer responded to his email item by item. For the most part, he agreed with what B John was saying except that his information and perspective were limited and missing key components of the scenarios he was talking about.  Mark explained why our listener’s comments were way too simple and cited some scenarios to illustrate this.  It was a fascinating reply to what many of us believe are already effective countermeasures.  Unfortunately, while what many of us suggest is correct, what we suggest does not go far enough and does not contain the specifics and details of what is actually required to make a specific countermeasure work.  Otherwise, the countermeasures are far more complex than what B John asked about in his email which you will hear me read on the program.  I asked Mark about genetic modification and that took us to the subject of personalized countermeasures.  We talked about pioneering/space settlement, childbirth & children in the space environment, even gender differences for BELO HSF.  I asked about the differences from his perspective of doing HSF to the Moon, an asteroid, Mars, or Deimos.  There are differences, don’t miss his response.  As the program was ending, I asked if a commercial company without gov. funding could decide to do a BLEO mission without all the costs and safety concerns of NASA.  Mark said it might be possible though the costs of the missions and the technology needed would make it very hard for a commercial company to carry out.  He said a short cut bare bones mission might be achieved by a commercial company but the risks for the crew would be extreme.  If you were running a commercial company and funding such a mission, would you accept these risks, plus the risk the crew might not be able to do much or be effective once they got to their destination? As the commercial company CEO, would that be a good use of company money or would you dismiss what people like our guest today have to say about these issues.  Let me know your thoughts by posting them on the blog.
