We welcomed Gerald Driggers to the program to discuss his theories about Mars settlement but his science fiction book series Earth-Mars Chronicles.  You can find out more about his work and books by visiting http://earth-mars.com.  During the first segment of our 100 minute program, Mr. Driggers talked about his early interest in space exploration, his early work in the industry & then his becoming a space age dropout as he described it.  He told us why he embarked on the Earth-Mars Chronicles series.  Listeners sent him email questions asking him why Mars was so important & why it should be the choice for human settlement off the planet.  Gerald responded to these early “why” questions.  A listener asked if he would do a one way mission to Mars. You might be surprised by his answer.  Next up was Mars One given Gerald was one of the early supporters of the organization.  Gerald had much to say about Mars One and the Mars One model for humans to Mars.  He also discussed other HSF to Mars Models but their was lots of listener interest in discussing Mars One with our guest.  Later, Gerald said we would need to be at the Technical Readiness Level 7 (TR7) to go to Mars, be it the private sector or with the government.  June emailed to ask about the minimum viable size for a Martian settlement,  including genetic screening.  Evon emailed about landing large payloads on Mars & how Gerald addressed that problem in his books.  Gerald  brought up the need for humanity to be off Earth in case Earth is destroyed so I asked him if we needed to be in a hurry to develop an off Earth presence on Mars.  Our guest suggested it would be a very long time in coming as there was no forcing function for HSF to Mars, nor is fundamental research being done regarding human survival on long duration spaceflight trips.  Doug called to ask about the economic justification for settlements on Mars & to ask if the Moon was not a better and more economic choice than Mars.

In the second segment, Kirk from Trinidad phoned in to ask about the online presence for Mars One.  We also asked him about space in Trinidad and if it was a hot topic or area of interest.  More emails came in & Christine wanted to know what was next for Gerald in Earth-Mars Chronicles.  Tony wanted to know if there was a spiritual component to HSF to Mars.  Our guest responded in the context of religions.  Judith’s note  inquired if one of greatest blockades to space exploration were the entertainment options today including video games, computers, & other forms of entertainment.

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 welcome you to today’s 2 hour 15 minute Open Lines discussion covering a wide range of topics.  Since both segments of the discussion overlapped and covered the same topics, this summary will not be divided into the typical part one and part two segments.  At the beginning, I threw out some possible discussion topics. These topics included my thoughts on the cubesat market becoming saturated due to the very low barriers of entry.  This typically happens in the business cycle leading to failures, buyouts, mergers, etc.  I posed the question if this could happen in the cubesat industry.  I also commented on the FATW issued to Mars One deeming it a suicide mission.  These seemed to be the two most frequently discussed topics on today’s show though SLS and Falcon did enter the discussion.  Regarding the cubesat industry, most callers thought that cubesats would not go the way of traditional businesses with low barriers to entry because the launch side of the industry has a choke hold on deployment of cubesats and so far does have low barriers to entry. The reasoning went something like this:  One could have all the cubesats in the world they wanted but only so many can get launched per year and this puts limits on the potential cubesat market. Many callers and a few email listeners had much to say on this discussion during the entire program.  Now as for the FATWA issued against Mars One deeming it a suicide mission, that too was a popular topic.  Many listeners commented on it as did I though I suggested it probably did not matter since I’m a skeptic that the venture will ever launch, especially given the stated time tables it is working against.  But there were lots of views on the FATWA. Most listeners agreed that Mars One would likely be something on the order of a suicide mission but calling for a FATWA seemed extreme. There were several sarcastic comments and SLS John objected to why we would even spend time talking about it given all the important things going on in space and the space related world.  Later in the second segment, Jeff called in and extended the discussion to SLS which is always volatile on TSS!  Jeff offered us some interesting observations and “givens” regarding SLS as a government program.

We welcomed back Drs. Jurist and Logan to this CLASSROOM program which addressed many issues of the 2 hours 1 minute broadcast.  We started out with Dr. Logan discussing fantasy or magical thinking going back to the influence of a 2001 Space Odyssey movie poster had on him.  From there, Jim went into a discussion about Constellation, then the Space Shuttle as examples of what he was talking about and as to how programs and faulty ideas grow and multiply.  He also talked about life science challenges.  A listener asked him about space politics, then Dr. Jurist offered additional examples with a focus on air launch.  Our guests then discussed thinking based on agendas and ideology.  One of the keys suggested for breaking out of this magical thinking mode involved surrounding yourself with really smart people.  Later, I offered my perspective on that given my own experiences early on in Space Show time and before.   Both Jim and John said a few times that one needs to know his or her limitations.  Our guests then talked due diligence with assumption building, fact checking, disclosures, and more.  I relayed my own wake -up call experience due to Al Zaehringer who was on the show several times years ago before he passed on.  Before the segment ended, Jim told us a story about the Wright Brothers and their Wright Flyer experience.  In our second segment, John Hunt called in to talk about Jim’s Space Shuttle comments.  This was a lengthy discussion with John, Jim, & John Jurist.  Jim talked about advantages with Saturn V including economic advantages over shuttle to LEO.  Subjects of reusability came up along with issues of getting a specific payload to orbit which our guests suggested advocacy often glosses over with facts and trades for payload mass fractions involved in reusability.  Dr. Logan brought up and discussed what he called NASA Brinkmanship Strategy.  Jim then talked about the reality of sending payloads to the ISS using shuttle.   Trent in Australia sent a message about magical thinking with Mars One.  Our last caller was Alan from St. Louis who said John and Jim were too negative in their discussion.  Alan then talked about using smaller rockets over heavy lift and was working to make the case that we have to work with what we have.  He also talked about evolving up from smaller, not starting off with the biggest.  Each of us responded to Alan.  It’s a discussion you do not want to miss.
