We welcomed back to the program Joe Carroll to follow up on his May 2011 Space Show Classroom program on the same subject.  Our panel members included Dr. John Jurist and Dr. Jim Logan. All of us were part of the May 2011 program on this same topic.  During segment one of our 2 hour 10 minute webinar, Joe Carroll went over his background, interest, and experience in the subject dating back to 1981.  Joe discussed his recent work and updates including his concerns for the rotation rate, Coriolis effect & the absence of any substantial progress in the area.  He directed us to Slide 2 & the specific language used in the 201 US National Space Policy introduction.  Our guests talked about missed opportunities by NASA & others to do the essential research needed to confirm the gravity prescription for humans.  Our guests also talked about the amazing amount of unknowns regarding the effects of microgravity or Zero G on humans as we are a 1 G species.  The issue of space settlements came up & I asked our guests if we were jumping the gun pushing settlements when so much of the human factors work remains unresolved and even unknown.  Joe talked about two extremes in the approach to settlements.  He said one extreme was to simply prove issues by walking.  That is, just try it.  The other extreme was to do “endless research and studies,” a critique often mentioned by space advocates.  Jim pointed out that essentially knowing nothing about the Gravity Prescription despite 53 years of human spaceflight experience doesn’t rise to the definition of “endless research and studies.” Apollo was the walking theory for the most part.  Our guests then talked about NASA plans for an outpost as compared to a settlement, specifically for the Moon.  During this segment, we received several listener emails which the guests responded to.  During this time, Jim continued to state that it was essential that we know at least the basic outlines of the gravity prescription for humans for long duration interplanetary spaceflight.  Our guests talked about the ISS and the role it could play in supporting gravity research.  Joe continued to discuss more of his slides and our panel members had much to say about the discussion. Toni called at the end of the segment to ask about 1 RPM spin rate and mentioned that SpaceX said it wanted to go to Mars by 2020.  Here is the article Tony referenced:  http://www.dailymail.co.uk/sciencetech/article-2634046/Elon-Musk-says-SpaceX-making-progress-Mars-colony-2020-plans-sell-tickets-500-000.html.

In the second segment, we decided to hold the listener emails until the end of the broadcast to allow Joe time to finish his slides and state his conclusions.  We started off with Slides 6, 7 & 8.  Joe progressed to talk about the inflatable tunnel, some of the technical aspects including specs and diameters and why one was better than the others.  Joe continued taking us quickly through the slides but for those interested in the details, pay close attention to them or contact Joe as his email address is on his presentation material.  Joe spent some time this segment talking about doing Gemini-like tether experiments and he also referred us to Robert Walker’s work.  Robert is a Space Show guest from the UK who has done excellent work on the issue of partial gravity based on Joe’s work with tethers, etc.  Check out Robert’s paper at
http://www.science20.com/robert_inventor/crew_tether_spin_for_artificial_gravity_on_way_to_iss_stunning_new_videos_space_show_webinar_on_sunday-137070.  Don’t miss the links to the tether spin videos in his paper.  The subject of rocket reusability came up and again, Joe and our guests had much to say about this so don’t miss it.  Also in this segment, there was more focus on spin rates.  Joe took us through is conclusion slide which is Slide 20.  He talked about the difficulty in selling space as the next stuff and said one never launches with cutting edge hardware.  We then fielded second segment listener emails on a variety of topics, then we talked about people wanting to go to Mars with the just do it concept mentioned in the first segment.  Several Dr. Zubrin comments were used as illustrations along with SpaceX plans to do Mars by 2020.  All of our guests said there was a significant difference in a short trip to the Moon with Apollo where the decision was made to take the risk for a few days but that going beyond LEO for a long trip to Mars for example was a totally different thing altogether.  Jim used long duration sailing voyages as an example of how the issues for the crew once the long duration trips were started turned out to be very vastly different than for short, easy, turnaround ‘sortie’ voyages. Once transoceanic voyages were attempted it didn’t take Captains, crews or their respective patrons long to realize long duration voyages came with radical new levels of complexity and increased human risk.  We talked more about tethers as well.  Jim made the point that the average time spent on the Moon per Apollo lunar moonwalker was only 2.06 days, a woefully inadequate time to ascertain increased risk.  Joe also talked about the possible study & use of 0.06 G as explained in Slide 8.  I asked each guest for their concluding remarks, starting with Dr. Logan.  His take away was that it is critical to know the gravity prescription. Dr. Jurist was next saying there was no useless research and that gravity research may very well benefit us here on Earth in ways we can’t even imagine at this time.  Joe summarized his concluding thoughts per his last slide, talked about his possible plans to be more proactive with his work and suggested easy experiments that could be done with a Dragon and the spent first stage even on an ISS mission.

Please post your comments/questions on The Space Show blog above.  You can reach all of the guests through me but as stated earlier, Joe lists his email address on his presentation material.

We welcomed Kevin Heath, CEO and President of Waypoint 2 Space, a new human spaceflight training company located near JSC near Houston, Texas.  Visit their website for more information, http://www.waypoint2space.com.  While our program was 90 minutes and covered two segments, since we talked about Waypoint 2 Space in both segments, along with their training program and plans, this summary will cover both segments as one.  We started our discussion with Mr. Heath providing us with an historical overview leading up to the creation of Waypoint 2 Space followed by the why of starting this business.  One of the important points made early in the discussion was the fact that Waypoint has received the FAA Safety Approval which is important, especially for the platform customers.  Kevin then went over their training plans and programs, explaining that they will have three main programs, a Level 1 Spaceflight Fundamentals; Level 2 Sub-orbital Training & Level 3 Orbital Training.  Waypoint also has a Commercial Payload Specialist Program which was explained to us.  Our guest went through the special equipment they have and will acquire as Kevin made the point throughout our discussion that Waypoint provided comprehensive spaceflight training.  As you will hear, the programs are being implemented as the markets appear. For example, the Level 3 Orbital Training Program will be delayed until there are orbital flights available for their customer base.  Kevin talked a lot about spacesuits in the training, having sizes for their customer base, and he described more regarding their comprehensive spacesuit training.  He also talked about making Waypoint broad to appeal to and serve a large and diverse market.  When asked, our guest went over the physical requirements for the program along with the guidelines for one’s health.  Listeners asked lots of questions, including wanting to know if training for focus, calmness, and on psychological concerns was part of the training.  Others asked questions about the training per se, space sickness, competition, and of course the pricing.  The price for the Level 1 Program is $45,000 & Kevin spent some time discussing pricing with us.  Later we learned that Waypoint has expansion plans that may even include a foreign type of franchise at various spaceport locations around the world.  Kevin was asked about special lunar or Mars mission profile and settlement training, plus I asked him if he used space tourism market studies in his creating the business.  Our guest had much to say about this particular subject.  Others wanted to know about class size, registration, & possible NASA endorsements to the training.

Dr. Erik Seedhouse, Sunday, 1-27-13

http://archived.thespaceshow.com/shows/1937-BWB-2013-01-27.mp3

Guest:  Dr. Erik Seedhouse.  Topics:  Dr. Seedhouse talked about his new book, “Pulling G: Human Responses to High and Low Gravity.”  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.

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 Dr. Erik Seedhouse back to discuss his latest book, “Pulling G: Human Responses to High and Low Gravity.  I strongly recommend this book as it is a terrific resource on the subject of G-force on the human body.  If you buy it using this URL from Amazon, Amazon will make a contribution to The Space Show:  http://www.amazon.com/Pulling-Responses-Gravity-Springer-Popular/dp/1461430291/ref=onegiantlea20.  Our 1 hour 42 minute discussion was in two segments but as our topics overlapped segments, there will be no part one and part two for today’s program summary.  Dr. Seedhouse began the discussion talking about the different types and sources of gravity on the human body.  This included acceleration, lateral, reentry, vibrational, and more. We talked about helmet restraint issues, Formula One race cars and taking corners at high speed producing a high lateral G force, jet fighters, rocket flight, roller coasters, and more.  Erik went over the proposed flight profile in g terms for Virgin Galactic and other proposed vehicles.  He also talked about centrifuge research and findings with the general public at the NASTAR facility.  He then switched to g-load force, fighter pilots and the Anti-G straining maneuver and breathing that they do to help counter excessive g’s.  Suborbital flight came up and here, Dr. Seedhouse had much to say given the small amount of suborbital human spaceflight history.  We also talked about bone loss and density issues, osteoporosis, and obesity.  Erik said the best physical profile for resisting high g force was short and stocky.  The worst was tall and thin.  Don’t miss his explanation for this. He also said smokers do better in high g’s over nonsmokers.  Erik got lots of question about the Bill Weaver SR-71 ejection.  Then he mentioned the Armstrong Line and said above that point, blood boils without a pressure suit. Erik also talked about orthostatic intolerance (OI) in the context of g tolerance.  He talked about professional astronaut training for suborbital missions such as with Astronauts4Hire.  We then discussed the financial problems hitting the Canadian aerospace industry with layoffs, closures, and the possible sale of valuable space hardware.  Listeners wanted to know about anti g countermeasures, if any, and laser eye surgery was discussed although Erik said it was no longer a problem.

Dr. Duane Graveline, Friday, 1-25-13

Co-Host Heather Archuletta

http://archived.thespaceshow.com/shows/1936-BWB-2013-01-25.mp3

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

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 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.
