We welcomed Dr. Bill Rowe back to the show for this nearly two hour discussion regarding medical risks for spacewalks and astronauts. During the first segment, Dr. Rowe focused on a possible astronaut magnesium deficiency that would cause cardiovascular problems, especially with a space walk. Dr. Rowe explained why, talked about the adrenalin levels being 2 times those on Earth plus decreased plasma levels. He spent some time explaining these issues, their relationships to one another and why he believes them to be risk factors. In his discussion, he referenced health conditions for some of the Apollo era astronauts, plus he talked about microgravity issues and a possible mitigation strategy of using I.V. saline with the astronauts in space. At times the discussion was medically and technically complex but Bill broke it down for those of us not in the medical profession. He also talked about his experience over decades of practicing medicine and being a diagnostician, referencing many of his relevant patient studies along the way, including for example his work with Sy Mah. Dr. Doug sent in an email regarding dehydration and a headward fluid shift. Toward the end of the first segment, Dr. Doug called in to suggest that if an astronaut did an EVA in a pressurized rover vehicle rather than an Apollo era spacesuit, adrenalin levels and other risks would be mitigated. This was an interesting discussion with Dr. Rowe who did not agree with Doug’s premise. Listen and let us know what you think by posting on TSS blog.

In the second segment, Dr. Rowe started off saying more about the use of I.V. saline with astronauts, a topic he discussed in the first segment. . BJohn had several email questions asking about spacesuit gloves and exoskeleton gloves given what Dr. Rowe was saying about finger tips and related items. Other topics discussed in this segment included the ISS, the one year Twins Study, Vitamin D usage in space, iron risks for spaceflight, plus the implication for some of these space risks to the problem of terrestrial urban pollution. As he has done before, Bill advocated for the need to have subcutaneous pharmaceutical administration for astronauts, then he addressed issues relating to the calcium-magnesium ratio. Bill provided us with a good set of concluding comments, plus he suggested healthy guidelines for our lives right here on Earth.

We welcomed Anthony Young back to the show to discuss the use of spacesuits in suborbital flight based on his Feb. 16, 2015 Space Review article, www.thespacereview.com/article/2695/1. During the first segment of our 1 hour 47 minute program, Anthony talked about his Space Review article and the Virgin Galactic accident from last year plus their goal of flying spaceflight participants in a short sleeve environment. We spent much of the segment talking about the pros and cons of using pressure suits as opposed to having a pressurized cabin and short sleeve environment. Anthony mentioned the other space vehicle programs and what he said were there plans to use pressure suits as opposed to non-pressure suit environment. Listeners asked him several questions by email. For example, BJohn wanted to know if the same spacesuit being talked about could be use for EVA purposes. Michael Listner took issue with Anthony comparing the early days of aviation to spaceflight saying the political, legal and media environment were completely different in the early days of aviation. He suggested that today a serious incident during a revenue-generating flight would raise a huge outcry and would probably kill the industry. Both Anthony and I disagreed with him on his conclusion.

In the second segment, we talked about work being done on a new generation of spacesuits for the commercial space tourism industry and Anthony mentioned several spacesuit companies and developers. He also talked about the special training Felix Baumgartner had to have to avoid panic attacks in the suit. Listeners continued with email questions including one asking if any airline companies had looked into suborbital flight. John in Florida called to talk about efforts to lower the cost for spacesuits. Toward the end, Anthony addressed his latest Space Review article which was about Sarah Brightman going to the ISS later this year (www.thespacereview.com/article/2724/1).

Guest:  Dr. John Jurist.  Topics:  High altitude sky diving, space vehicle crew escape, free fall from space.  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 Dr. John Jurist back to the program to discuss his latest research dealing with high altitude bail out, space vehicle crew escape, free fall from space, and more.  Dr. Jurist introduced us to the subject by talking about the history of experiments and research in the 50’s and the 60’s for high altitude bail out and the possibility of orbital speed crew escape.  He discussed many technical issues and jump/escape parameters so do listen carefully to our entire discussion.  Issues we addressed included aerodynamic stability, acceleration, deceleration, turbulence, spinning, heat dissipation, and the need to trust one’s equipment.  For example, he cited the famous Capt. Joe Kittinger jump as well as the latest effort to surpass the Kittinger jump by Red Bull and Felix Baumgartner.  Dr. Jurist discussed the differences in suborbital and orbital bailouts and we discussed the generic escape scenarios for upcoming suborbital flights.  John talked about the old Air Force Project Moose program and a listener asked about a free fall from orbital flight, perhaps from the ISS.  Dr. Jurist explained how this might happen and what would be needed for the person to deorbit, free fall, return to the atmosphere, and to survive the experience.  We also talked about the possibility of entering the atmosphere at too steep an angle and skipping off it with the potential of not ever returning.  He said this would not happen.  Don’t miss this fascinating discussion.

In our second segment, Carl asked Dr. Jurist to explain the SR-71 accident that he mentioned in the first segment. This is an amazing story.  You can read about the SR-71 incident described by Dr. Jurist at www.916-starfighter.de/SR-71_Waever.htm.  When asked for lessons learned, John said always trust your equipment and your training.  We talked about cabin pressurization in this segment and John got lots of questions comparing aircraft pressurization systems to those of a space vehicle.  This brought up the use of pressure suits, space suits, and possible shirt sleeve environments for space vehicles.  Later in this segment, John talked about spinoffs, specifically accident improvement with results showing up in the auto industry with safer cars.  Later, he was asked if he thought we were on the right track with HSF crew safety and escape issues and he said we were and that it was an evolutionary process.  Near the end of the program in response to a question, he said the most likely failures would take place in the boost phase of the flight.  Informed consent was mentioned as an issue to be aware of, then he concluded by saying that people are tough and can survive accidents and catastrophic events with the proper equipment and training.
