Guests: Dr. Duane Graveline, Heather Archuletta. Topics: Bed rest microgravity simulation studies. Dr. Graveline is the father of this research.

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. If you have questions/ comments for Dr. Duane Graveline or Heather Archuletta, post them on The Space Show blog per the URL above. If you want to email Dr. Graveline or Heather, you can do so through me. You can also comment and contact Heather through her blog which is mentioned earlier in this summary.

About our guests...

Heather Archuletta
Heather Archuletta was born and raised in San Francisco, and has degrees from Mills College in nearby Oakland, and the University of London, England. She loves to travel for both jobs and leisure, having lived in 7 US states and visited 47. After working in the tech industry for 17 years at large corporations like Oracle and Western Digital, she joined a NASA program for space flight simulations, which studies the long-term effects of weightlessness on the human body. These projects help Johnson Space Center scientists learn more about how to keep astronauts healthy in space for long duration flights, and she now works to find other qualified applicants for the programs. Her "Pillow Astronaut" blog (http://pillownaut.blogspot.com), which describes the flight sims in both personal and medical detail, has been featured in Wired, Popular Science and FOX news in America, as well as news outlets in Europe, India, Scandinavia and Russia.

Dr. Duane Graveline
Dr. Duane Graveline is a family doctor, aerospace medical research scientist, USAF flight surgeon and NASA astronaut, Duane Graveline MD MPH was born and raised in Newport, Vermont. He vividly recalls his idyllic life on a dairy farm and his eight years at the nearby one-room school where the same teacher guided him from the alphabet through algebra. Following graduation from the Vermont College of Medicine in 1955, Dr. Graveline interned at the famed Walter Reed Army hospital during the time our space pioneers were just beginning to study the medical effects of space flight. Becoming a flight surgeon and doing space medical research was almost inevitable to this young doctor with stars in his eyes. Soon came the Today show, international recognition for his research on zero gravity deconditioning, his unique position as medical analyst of the Soviet bioastronautics program, assignment as NASA flight controller and finally, in 1965, his selection as NASA scientist astronaut. Graveline still is affiliated with the space program as consultant to the special cosmic radiation hazards to man of “return to the moon and on to Mars.”
