We welcomed back to the show Dr. John Logsdon to discuss his new book, “After Apollo? Richard Nixon and the American Space Program.” During the first segment of our 90 minute discussion, Dr. Logsdon provided us with the multi-year history behind his researching and writing this book. We talked about the Space Shuttle but also the gap within NASA and parts of the space community including the advocate community between having great expectations but insufficient resources to support the great expectations. We talked about the likelihood of significant NASA budget increases in coming years and while possible, our guest said it was unlikely. President Nixon wanted space to be considered routine and NASA to compete for funding with other parts of the discretionary budget. What President Nixon set in motion is continuing through this day. Dr. Logsdon said policy normally comes from the White House but recently policy for SLS came from the Senate because they did not like what President Obama was doing. We talked about the long range impact of the Nixon space policy even through today and at one point Dr. Logsdon suggested that maybe Nixon got it right regarding American public sentiment about space. Our guest received questions about planetary science and its accomplishments and other listeners inquired about public/private partnerships. Still, our guest said that only governments really have the resources to carry out the type of space investment needed for exploration. Listeners asked about other forces of the time including the Cold War and space policy champions in leadership positions such as Tom Paine who was the NASA Administrator. Dr. Logsdon was asked how things might have been different had Hubert Humphry been elected president. Mars was also discussed, then Dr. Logsdon talked about the space shuttle history. In response to several questions, he shared his thoughts and experiences from his time spent serving on the CAIB. Another topic in this segment dealt with space advocacy. Our guest said we need advocacy to keep the dream alive until leadership makes it happen. He said talk about settlement and pioneering were mainly just words. Pioneering needed to answer two questions which he addressed before the break.

In segment two, we talked about the ISS and Shuttle having consumed the HSF budget and now the ISS does that with about $3 billion per year. Using the shuttle for national defense and security during the Nixon years was also a discussion topic as Nixon liked national security issues. Dr. Logsdon had much to say about the shuttle’s use by the military and for national security. You might be surprised by what you hear. As for human spaceflight, Dr. Logsdon referred her to the NRC Pathways Study which we have discussed many times on The Space Show. More questions came in regarding space advocacy which he said pushes the boundaries of realism and needs to be balanced between sober reality and pure fantasy. Tony emailed us to ask about SLS/Orion, private space over NASA, and Elon Musk and his Mars settlement plans. A question came in about being motivated by the Chinese space program. For closing remarks, Dr. Logsdon addressed the Nixon space policy and program legacy which still influences us today.

We welcomed Dr. Mark Shelhamer, Chief Scientist of the NASA Human Research Program to the show to discuss the critical risks associated with BLEO long duration HSP. You can hear his FISO talk on this topic from April 2, 2014 at http://spirit.as.utexas.edu/~fiso/telecon/Shelhamer_4-2-14/Shelhamer.mp3.  His associated Power Point can be downloaded at http://spirit.as.utexas.edu/~fiso/telecon/Shelhamer_4-2-14/Shelhamer_4-2-14.ppt.  During the first segment of our 95 minute discussion, Dr. Shelhamer started off saying  we would be talking about beyond low earth orbit only and that many of the risks are unknown since we have very little experience with BLEO.  Much of what we do know is extrapolated from our current knowledge base plus our Apollo experience.  Next, our guest defined three major areas/issues.  First he listed medical issues which he later described as onsite medical treatments for various complications, illnesses, surgical needs and such.  He classified physical deconditioning issues such as muscle and bone loss issues, cardio vascular issues in a different category.  The second group he identified had to do with radiation, and the third group included psychological-social issues.  I asked about Microgravity not being in the top three and he said because those issues are likely a constant for both LEO and BLEO missions.  He then talked at length about the challenges needing countermeasures/mitigation.  He did not say these were showstopper challenges but they do require effective countermeasures.  For example, he said humans could probably survive a trip to Mars today providing the hardware & life support was up to the job but their goal is to get the crew there in good condition, to be able to do effective work, and to return safely.  He did not think those goals could be obtained today.  I asked if money was a primary issue and it was not though he said more money is always helpful. He talked about the time needed for some human studies, team studies, and research, sometimes extending even longer than a year.  He then took us through the three categories to tell us what NASA was doing & how it was doing in that research area. You might be surprised by what you hear.  I certainly was.  Later, we talked about ocular/vision issues which are now getting front page attention.  He explained the latest theory causing the problem as possible fluid shifts.  Listen to this discussion.  Note that once we start with BLEO HSF, we may find other problems that do not now show up now.  Also, we may develop a countermeasure for one problem but that opens the door to lots of other problems currently unknown.  One tool he talked about that was being tested on the ISS Russian sector was lower body negative pressure.  Artificial gravity was a big part of our discussion.  While everyone is enthusiastic about it, he made the point of saying we don’t know the needed spin rate nor do we know what level of gravity is needed for humans or for how long. Just spinning a spacecraft without knowing this information is unlikely to be successful let alone cost effective or economic. He also pointed out that artificial gravity is costly, requires lots of energy, a huge spacecraft which means lots of mass to orbit, & to do it, it needs to be done in a way that maximizes the benefits for the crew.  Without knowing the precise spin rate and gravity needs for humans plus how long the crew needs to be in artificial gravity, it is likely it won’t be done just for cost and economic reasons alone.  Charles emailed in about bed rest analog studies.  Joe sent in a question about lower back pain & spine issues.  As the segment ended, I asked him if humans were lousy candidates for BLEO spaceflight.  Don’t miss his answer.

In the second segment, we took a call from Dave about nuclear submarines as an analog for HSF studies.  Our next topic was space radiation which our guest discussed in detail.  I then took two email questions from B John in Sweden.  He asked about the benefits of microgravity for disabled folks, then I read a longer email from him suggesting solutions for the microgravity, psychology, and radiation issues already existed and why was NASA not proposing and developing “these simple non-medical solutions to the problems you describe.”  Dr. Shelhamer responded to his email item by item. For the most part, he agreed with what B John was saying except that his information and perspective were limited and missing key components of the scenarios he was talking about.  Mark explained why our listener’s comments were way too simple and cited some scenarios to illustrate this.  It was a fascinating reply to what many of us believe are already effective countermeasures.  Unfortunately, while what many of us suggest is correct, what we suggest does not go far enough and does not contain the specifics and details of what is actually required to make a specific countermeasure work.  Otherwise, the countermeasures are far more complex than what B John asked about in his email which you will hear me read on the program.  I asked Mark about genetic modification and that took us to the subject of personalized countermeasures.  We talked about pioneering/space settlement, childbirth & children in the space environment, even gender differences for BELO HSF.  I asked about the differences from his perspective of doing HSF to the Moon, an asteroid, Mars, or Deimos.  There are differences, don’t miss his response.  As the program was ending, I asked if a commercial company without gov. funding could decide to do a BLEO mission without all the costs and safety concerns of NASA.  Mark said it might be possible though the costs of the missions and the technology needed would make it very hard for a commercial company to carry out.  He said a short cut bare bones mission might be achieved by a commercial company but the risks for the crew would be extreme.  If you were running a commercial company and funding such a mission, would you accept these risks, plus the risk the crew might not be able to do much or be effective once they got to their destination? As the commercial company CEO, would that be a good use of company money or would you dismiss what people like our guest today have to say about these issues.  Let me know your thoughts by posting them on the blog.

Please post comments/questions on TSS blog above. Mark can be reached through me or through his PPT presentation address.

Dr. Neil deGrasse Tyson, Friday, 3-8-13

Guest:  Dr. Neil deGrasse Tyson.  Topics:  Dr. Tyson’s book, “Space Chronicles: Facing The Ultimate Frontier,” delusional thinking, space exploration, space economic power.  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.

We welcomed backed Dr. Neil deGrasse Tyson to this 60 minute discussion about the new release of the paperback version of his current book, “Space Chronicles: Facing The Ultimate Frontier.”  If you buy the book with this Amazon link, Amazon will make a contribution to The Space Show/OGLF:  http://www.amazon.com/Space-Chronicles-Facing-Ultimate-Frontier/dp/0393343626/ref=onegiantlea20.  The book is a collection of all of Dr. Tyson’s thoughts about the past, present, and future in space.  It consists of essays, tweets, op-eds and more, plus an appendix with important documents such as the original agreement creating NASA in the late 1950s.  Neil said that some of the points he made in the book were that space was expensive and that we do things in space for one of two reasons: 1.  As a result of military threat or war; 2: In support of economic growth of the country.  He then supported his argument with historical facts, making the point that we do not explore for the sake of exploring, that exploration is not in our DNA, that we do not go into space to inspire future generations of kids, and then he even mentioned that the famous JFK Rice University speech which he said was a lie in that weeks before in a speech before Congress, President Kennedy put forth the real reason we were going to the Moon which was to show the world a path of freedom over tyranny.  Dr. Tyson documents this on p. 192 of his book by saying that “Kennedy did adopt a military posture in his speech to Congress.”  Neil stressed this point during our discussion in support of the above reasons for developing.  More about this speech can be found at www.history.com/this-day-in-history/jfk-asks-congress-to-support-the-space-program.  The actual text of the speech can be seen at www.jfklibrary.org/Asset-Viewer/xzw1gaeeTES6khED14P1Iw.aspx.  Dr. Tyson also talked about the problem of delusional thinking among space enthusiasts, a theme we went back to several times during our discussion.  Another point he made was about the importance of innovation and having a culture of innovation with space goals supporting the economic growth of an innovative nation.  Kelly asked a question about the best way to increase NASAs budget in bipartisan support of space for STEM, inspiration, spin-offs, etc.  Our guest said all of the reasons cited in Kelly’s question were irrelevant.  Don’t miss what he said.  We also talked about the need for infrastructure and Neil said that governments have to pave the way for the frontier and the private companies follow and economically develop it.  He said the commercial companies do not and will not be able to open the space frontier with the needed infrastructure.  I then depicted government as sort of an advance man in space with the privates being able to capitalize that infrastructure development for profit & national wealth. A listener asked about China, a space race, and a possible space war.  Dr. Tyson also said that we should have launch vehicles that go everywhere for research and innovative reasons and we needed to shift our culture to seeing space as a long term national investment for creating wealth for the nation, far beyond the term of our elected officials.  He talked about SpaceX and the need for a rich and fertile collaboration between government and the commercial companies regarding space.  I asked our guest about testifying before Congress. You will want to hear what he had to say about that based on his experiences in do so.  We talked about space and grass roots movements. He talked about GDP economic growth during the Apollo period and then what happened each decade after that through the current period.  Jim sent in a question pointing out possible contradictions in his comments & suggested fuel depots as a way to minimize the quantity of rockets and launches. Dr Tyson said he was hardware agnostic and that in developing infrastructure and paving the way for the privates in space, fuel depots might very well be part of infrastructure but that government would be doing them, especially early on.  Later, Dr. Tyson talked about our system being a political system and that it was not going to change.  He used this as one of the examples of delusional thinking given many enthusiasts who don’t accept this reality & believe they can bypass or work around the political nature of our government and systems.  Near the end of our discussion, he was asked about the Inspire Mars mission which he said was probably a stunt but that it might serve the purpose of showing the government that lots of people are interested in an HSF to Mars.  Another listener wanted to know if the Inspire Mars mission turned out bad, would it derail human spaceflight.  He did not think it would do that given other space accidents with the loss of crew.

Please post your comments/questions on The Space Show blog and I will call them to the attention of our guest.
