Contact The Space Show for further information.  We welcomed Dr. Duane Graveline to the program to discuss bed rest simulation microgravity studies, the early days of pioneering of his having pioneered this research, aerospace medicine and much more in our 1 hour 23 minute discussion. Dr. Graveline is the father of this research dating back to the late 1950s.  Please visit his website, www.spacedoc.com.  Heather Archuletta, the Pillownaut Astronaut, returned to co-host with me for this important discussion.  Check out Heather’s blog posts about Dr. Graveline and his work at http://pillownaut.blogspot.com/2013/01/the-bed-pilot-pioneer.html.  Dr. Graveline has allowed us to use two specific pictures referring to his pioneering work and both are on The Space Show blog per the above URL.  Picture 1 is Dr. Graveline’s water immersion tank and Picture 2 is the LBNP device. He discusses both of these in the program’s first segment.  Dr. Graveline started out with an overview of his early work, how he got into the field, his decision to join the Air Force and why this area of medicine interested him.  He explained his early bed rest tests and talked about the challenges with the test subjects. Heather and Dr. Graveline compared those early tests to those of today that Heather has participated in.  It was a fascinating compare and contrast, especially regarding the discipline of test subjects then and now. Dr. Graveline talked about water immersion, the aerospace lab he used, and his water immersion tank.  Don’t forget to check out the picture of it on the blog.  Dr. Graveline is looking through the window at the floating test subject.  Would you like to float as Dr. Graveline explained for one full week nonstop?  Throughout our discussion, Dr. Graveline told us many interesting and sometimes funny stories from his past like his visit to the Today Show and their wanting him to wear “flippers!”  Our guest described the low body negative pressure device (LBNP) which you can see in the second photo on the blog.  He talked about it, the old Soviet program, Mir and tilt table tests.  Dr. Graveline talked extensively about the Soviet program, how he was able to monitor much of their data, & he told us about Alexi Leonov when he had serious problems when caught outside his spaceship.  Many questions were asked about early animal studies, Laika, and more.  He told us how they were able to do blood pressure readings on dogs & the Soviets bragged about it since Dr. Graveline was able to figure out, copy, & improve the Soviet system.  Mice and centrifuge studies were discussed in some detail & Heather and Dr. Graveline had comprehensive discussions about exercise in the bed rest studies of today as compared to none in the early days of the studies. Dr. Graveline talked with Heather about his idea to abandon exercise in space so the astronauts could concentrate on their work, then return in a hydropod and rehab completely back on Earth for a few months.  You don’t want to miss this discussion or explanation from Dr. Graveline as to why this approach should be considered and tested by NASA.

     In the second segment, we talked about bone density issues and the applicability of space research and findings to terrestrial medical issues for people with this medical problem.  He was asked about a long duration HSF to Mars and he said the bigger problem was galactic radiation which he talked about in some detail.  He said that as of today, there are no mitigation tools for this problem.  The discussion went back and forth about water immersion and the use of the hydropod for returning astronauts & Heather talked about prohibitive costs & that immersion is not used today.  One of our UK listeners asked Dr. Graveline about his being part of Group 4 – The Scientists.  As this was the first astronaut group that was not composed of test pilots, our listener wanted to know about the selection process & getting more scientists to the Moon & on missions.  Dr. Graveline had much to say about this subject & shared with us some terrific & historical stories from the past.  He talked about Spacelab, astronaut Bill Pogue, & shared science stories with us.  During our program, Heather, with her bed rest study experience & her recruiting work (listen to her Space Show program on the studies she has recent completed at http://archived.thespaceshow.com/shows/1926-BWB-2013-01-08.mp3 from Jan. 8, 2013), contributed greatly to the discussion and Dr. Graveline was equally interested in talking with her about the program today as compared to the program he started decades ago.  Dr. Graveline’s book, “From Laika With Love: Secret Soviet Gifts to Apollo,” is still available. If you order it from Amazon using this link, Amazon will make a contribution to The Space Show/OGLF:  http://www.amazon.com/From-Laika-With-Duane-Graveline/dp/1424338700/ref=onegiantlea20.  Dr. Graveline was also asked about the use of his research today and if young scientists & researchers interested in the field still study his early work.  He said yes and talked about how much easier it was to do that today due to the internet.

Guest: Heather Archuletta.  Topics:  NASA bed rest and simulation studies.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, https://thespaceshow.wordpress.com. Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information.  We welcomed Heather Archuletta to the program to discuss her first hand experiences with three NASA bed rest studies plus her recruitment work for new NASA study applicants.  Heather is known as the Pillow Astronaut.  Check out her website at www.pillownaut.com and her blog at http://pillownaut.blogspot.com. Our discussion was divided into two segments but this summary will not reflect segments since many of the same themes and topics overlapped the two segments. I believe this to be a very informative and a very entertaining Space Show program offering a comprehensive and insiders view of a subject we have not covered in any detail on any of our programs in our broadcasting history. We started out with Heather explaining the bed rest simulation studies, the different kinds of studies, and the basic qualifications to participate in a study.  We talked about studies ranging from 24 days to 100 days.  Heather was terrific about explaining the protocols to us, what each day was like, what the food was like, the ongoing medical testing, the helpers that did practically everything for the participants, plus the type of recreation they had given they all had to remain in their beds in the position required by the specific study.  We talked extensively about the recreation from reading to movies, to being able to get fresh air outdoors, to using computers, webcams, and phones.  Heather also explained the personal and privacy issues all the participants had to comply with and experience.  If you embarrass easy, these studies are likely not for you.  Diet was a big part of the study and our guest explained how tightly controlled the diet was and how it was made to order for each participant.  In response to questions about the application and process, we learned about the medical and psychological screening, bone scans, etc.  There was also outreach to family, friends, and significant others as there were strict rules about visiting and of course applicants did not need opposition by those in their lives.  The goal of these studies, as you will hear, was to work toward developing counter measures for the effects of microgravity on bones.  Physical intervention techniques such as exercise were tested as well as chemical mitigation techniques depending on the nature of any given study.  Several listeners asked why the participants chose to do this.  One listener asked how Heather talked with the general public to get them to see that spaceflight was worthwhile.  Don’t miss this discussion, it’s a good one.  Making a difference and helping to pave the way for long duration human spaceflight were important reasons given by the participants for enduring the study constraints and protocols.  Heather went over the basic medical and physical requirements for being a participant and she talked about her getting others interested in the studies given her own experience with three studies.  She uses social media for outreach and also various conferences and speaking engagements.  Heather also told us about the pictures on her blog, including pictures of her doing the studies in her bed.  Scroll down on her blog for more information and the pictures. Also, there are journals on the blog regarding the day to day activity in the study.  We learned that reading was a favorite activity as was working on laptops.  When Heather was asked about pets coming to visit them with family members when visiting was possible, we learned that some of the participants kept fish with them in their rooms but no dogs, cats, or birds.  Later in the discussion, she talked about the use of smart pills in some of the studies.  She mentioned the founder of the bed rest studies, Dr. Duane Graveline and she told us how the bed rest  and water immersion studies came about. Heather also said that the term “sleep study” was incorrect as the participants were not there to sleep!  We learned that when the study ended, there was about a two week rehab period for the person to be able to function again.  Sometimes the participants could not drive for up to three weeks after the study ended.  Listeners asked Heather how accurate the simulations were compared to what the astronauts experienced on the ISS and the space shuttle.  As you will hear, these studies appear to be excellent analog studies to actual spaceflight.

  One additional point and that is we talked about the Whitehouse.gov petition on nuclear propulsion. For those of you interested in this petition, you can get information about it at http://cosmiclog.nbcnews.com/_news/2013/01/08/16385852-nuclear-power-in-space-petition-asks-white-house-to-rekindle-project.
