Co-Host Heather Archuletta


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

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.

Rick Searfoss (Col, USAF RET.), Monday, 6-18-12


Guest:  Rick Searfoss (Col., USAF, RET.).  Topics: Rocket Flight, XCOR, Lynx, flight safety, leadership.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, https://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright.  We welcomed back to The Space Show Rick Searfoss to discuss spaceflight flying, XCOR Aerospace, the Lynx, and much more.  You can learn more about Rick Searfoss by visiting his website, www.astronautspeaker.com.  For more about the Lynx and XCOR, visit www.xcor.com.  We started our discussion with an overview of a successful test flight program.  During this discussion, our guest made it clear that flight tests are supposed to detect the unknown and to catch problems in time for them to be fixed prior to surfacing during commercial operations.  The test pilot is prepared for the unknown and this is why he later said that future XCOR pilots would need to have U.S. military test pilot school experience along with their military flight experience.  Also, the testing starts out very slow and escalates based on the progress and analysis of the tests.  One crawls before one runs, so to speak.  I asked him to compare a spaceship test flight program to information I had on a new Boeing 747-8 Intercontinental Jetliner that Boeing was putting through 600 flight hours of flight tests (www.examiner.com/article/new-boeing-747-8-intercontinental-maiden-flight).  Don’t miss this discussion, its interesting, important, & relevant.  Col. Searfoss received an email from Jeremy asking about humans riding on solid rocket boosters (SRB) and the safety in doing that.  This resulted in another interesting discussion.  We then talked about piston pump technology, suborbital flight, turbo pumps, and the XCOR program working with ULA regarding hydrogen pumps.  I asked Rick to describe the Lynx flight from the passenger perspective.  Doug wanted to know about the first flight timeline for later this year and then Christine wrote in asking if the Lynx cockpit would have dual controls similar to an airplane.  A question came in about the Chinese rendezvous & docking per their current mission & Rick’s take on the process given his space shuttle pilot experience.  Rick talked about this with the shuttle in some detail.

In our second segment, Terry called in to ask about the XCOR flight software.  As you will hear, XCOR flight software means humans.  Listen to what he had to say about this, including issues with space shuttle software.  Our guest then talked more about the flight readiness process including the Technical Review Board and Safety Review Board process.  Other topics discussed included citizen science on board the Lynx, ITAR issues, additional Lynx pilot qualifications, and defense dept. applications for Lynx and the suborbital industry.  Lee called in to ask about an evolution to an orbital vehicle, other questions came in regarding runway requirements, passenger height & weight requirements, and spaceports.  Near the end of our discussion, we talked about an emergency exit from the Lynx, spacesuits and bailout.  Also discussed throughout the program were suggestions for the passenger to better prepare for his/her flight.
