We welcomed back Dr. John Jurist to discuss some space program related medical and biotechnical advancements to illustrate some of the benefits and importance of human spaceflight. Listeners also asked him about radiation and one listener in particular answered my question as to why so many space advocates & enthusiasts dismiss the human factors when planning their versions of a humans to the Moon or Mars mission. During the first segment of our 90 minute discussion, Dr. Jurist talked about the former astronaut Deke Slayton’s experience with NASA and spaceflight during NASA’s early days when it was discovered that Deke had atrial fibrillation (afib) regarding his heart rate. Given that I’ve made it public that afib was the reason for my medical leave of absence plus I talked on air about my cardiac ablation procedure at UCSF Medical Center, it seemed appropriate for Dr. Jurist to open with that topic. Dr. Jurist showed how Deke’s afib experience was in many ways, with NASA research, the root of biotechnology and patient monitoring, wireless monitoring, and even the early days of afib research. He talked about early space and aviation companies making the monitoring devices for the patient & medical public though this is hardly ever mentioned when talking about NASA spinoffs. Listeners and I asked lots of questions about these advancements coming from sources other than NASA had NASA not been around. Would we have had them anyway and around the same time? Don’t miss what Dr. Jurist had to say in response to this line of questioning. Dr. Jurist also spoke about bone density issues and osteoporosis analysis and mitigation devices and drugs, many of which have been tested and used in space. Also, aerospace companies made the initial hardware used for bone density analysis. Other human factors issues came up and were discussed including vision problems such as a higher incidence of cataracts for astronauts, plus issues probably resulting from fluid shifts in the eye due to microgravity. John talked about the use of ablation procedures throughout the medical profession and Holter Monitoring for cardiac issues. He also noted that early bone monitoring was developed by lunar related companies. Our guest was asked just how important the medical advancements are to HSF and he said very important but they have been undersold to policy makers and the public. They are also complicated to explain and understand. Radiation was discussed and turned out to be a significant part of the discussion in Part 2 of our program. Toward the end of the segment, I asked why so many space enthusiasts seem to dismiss the human factors. Fortunately, B.John in Sweden provided what I think was an excellent answer to the question which we took it up in the second segment. However, his note said the following: “About 500 humans have been to space. No increase of radiation related health effects have been observed. No one have died in space, only during starting and landing. And that’s because of technical malfunctions with catastrophic explosions. That’s why most listeners think that Dr. Jurist grotesquely over estimate the imagined hazards of space flight. There exists no data at all to support his pessimistic claims.” While I disagree with his analysis and conclusions, I do think his reasoning is held by many and it does go a long way to explain why so often the human factors issues are dismissed by some in the greater advocacy community. Before the segment ended, I asked John to talk about the April 4, 2014 presentation at Rocky Mtn College by Walt Cunningham. The video of Walt’s talk is on our Space Show Vimeo channel and the audio is now archived on our website and blog.
In the second segment, Dave Ketchledge called to speak to the radiation issue as Dave was part of the nuclear Navy and worked in the nuclear power plan industry for years. He had much to say about the radiation risks that debunked B.John’s comments. Both he and Dr. Jurist spoke to beta and alpha particles, some shielding material ideas, & changes in the radiation standards used by NASA. Later, Dr. Jurist responded to a question about space being engineering driven with the medical issues not always receiving the top priority in architecture development and mission design. B.John sent us additional emails regarding radiation, supporting art. gravity, and suggesting why NASA does not want to do HSF. Don’t miss our responses to B.John’s emails though I said again I thought his explanation to my initial question was on the mark. In his summary, Dr. Jurist suggested the bio medical field received important benefits from our early and ongoing space program. He also said going to Mars, the Moon, or an asteroid would most likely produce huge benefits and medical advancements, and that should be reason enough to have a robust human spaceflight program.

We welcomed Frank Stratford back to the program to discuss various commercial space business models, including nonspace revenue generating goals and objectives. Frank is the founder of MarsDrive so for more information, visit their website at www.marsdrive.com. During the first segment of our 1 hour 42 minute program, Frank introduced us to the topic in his April 22, 2013 Space Review article, “The Business of Space Travel” (www.thespacereview.com/article/2281/1). Frank talked about the need to generate nonspace revenue while building up the space company & space revenue R&D, activities, & markets. He cited SpaceX, Bigelow, & Blue Origins as examples. This led to a discussion about markets & financing, plus estimated costs for a human spaceflight mission to Mars. Frank compared the Mars One $6 billion estimate to his own estimate from his research to be $15 billion. Our first caller asked if big name investors associated with these early commercial space ventures created an expectation of success and may in fact turn out to not have been such a good idea. The detailed discussion included ROI, Stratolaunch and the revenue cycle gap from up front/early capital needs to revenue generation later on in the project’s cycle. We talked about the nonprofit or charity model and Inspiration Mars came to mind. I entered the discussion with comments about the need for repeat customers, a commercial space success to model, unrealistic assumptions, the lack of due diligence, and the difficulty in cost estimates, especially when the cost of getting to the destination (the Moon for example) is unknown at this time. Surrey Space & Technology was also brought up as an example of a good business to model.
In the second segment, our called pointed out a Moon & Back interview with Robert Bigelow in which our caller said Bob said he went into the r/e business to fund his space activities. Later, he email in additional comments suggesting that just because a space venture or idea is not funded does not mean it’s a bad idea or concept. He then advocated NASA support such as with COTS and Commercial Crew. Public/private partnerships were advocated as a good way to move forward with space development and exploration. Frank was then asked if a failed commercial project would hurt the industry. He said it was possible. Another question came in regarding paying attention to human factors and if solutions would be available at the same time as engineering technology, financing, and maybe markets. Frank said only if work moved forward on human factor solutions at the same time and at a similar rate. He also advocated his own organization working the problems. Listen to his reasoning behind this. As the program was nearing close, Frank was asked if Curiosity found proof of life in the past or now, even the most basic life, if it would make HSF to Mars more of a priority. Don’t miss Frank’s response. In summary, Frank talked about the need for continuous incremental development.

We welcomes Dr. Roger Launius back to the program to discuss his latest book, “Coming Home: Reentry and Recovery from Space” which is a free download at www.nasa.gov/pdf/695726main_ComingHome-ebook.pdf. During our first segment, our guest provided us with a short history of resolving challenges with reentry from space with human spaceflight. We discussed winged vehicles and capsules from a historical, practical, and engineering perspective. We also talked about DOD influence and the advantages as well as disadvantages of both types of space vehicles. One listener question asked about winged vehicles evolving from suborbital to orbital HSF. Terry called in with ballistic reentry questions about the V2 rocket & we mentioned museum locations where people can see a complete V2 on display. Another listener wanted to know if there were any winged vehicle concepts for Mars. Here, our guest talked about some science fiction examples but nothing for real on the drawing board. Our guest then introduced us to magical thinking and we talked about reality in space exploration as compared to fantasy. As this segment was ending, we talked about RLVs and reentry issues.
In our second segment, we started off talking about the NASA budget and the potential impact of sequestration. Our guest said human spaceflight is the biggest challenge and in fact at one point he said we were just one banana peel away from losing HSF! This was in the context of access to the ISS with only the Soyuz and how fragile the access was until we had multiple ways of getting to the station. We then discussed risk and some of the issues raised on this subject by other Space Show guests that believe we need more risk to advance human spaceflight. Risk was also discussed in the context of hypothetical ISS recue missions with HSF vehicles not yet ready for prime time. We also talked about the value and purpose of HSF, including should settlement really be the purpose of it. We had a lengthy discussion on this subject. Both Roger and I suggested the purpose of HSF is a challenge, can be illusive, and is probably something larger and broader than space settlement. Don’t miss his explanation behind his thinking. We also talked about spinoffs as a reason for HSF, the we addressed the lack of needed infrastructure, radiation issues, etc. Toward the end, we took some questions about SLS and heavy lift. Jane asked our guest about the visitors to the Air and SpaceMuseum at the Smithsonian & if Roger could infer an increase or decline in the interest in space by the visitors or if the visitors had an awareness of the challenges facing NASA and HSF.
