Guest:  Alan Boyle.  Topics:  Space news, space policy, budgets and insights.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://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 Alan Boyle to the program.  I recommend you follow and subscribe to his blog Cosmic Log at http://cosmiclog.msnbc.msn.com.  In our first segment, Alan shared his views on space policy and the presidential candidates, developments and issues with commercial space and crew efforts, and the space vision for BEO.  Specifically, we talked about Newt’s proposed policy, American statehood for a lunar colony, the Outer Space Treaty (OST) and Alan’s view that he thought overall Newt’s comments were not that helpful to his campaign.  To a lesser degree, we talked about the Romney space policy.  Also on the discussion table were large government projects and he referenced a few that seemed better than most such as the Large Hadron Collider and ITER.  We also talked about the fact that in the previous administration, having a lunar outpost that eventually was to become commercial was our national space policy up until the new administration cancelled the program.  Alan was asked several questions about commercial crew and he referenced comments made by Boeing that the business case for now does not close without government support.  We also talked about the gap and the readiness of commercial crew to the ISS.  During this discussion, I mentioned what I had heard about Space X and its schedule for flights prior to 2017.  During the show, I contacted Space X, got a clarification of what I had heard and read it on air near the end of the program.  I appreciate the timeliness of Space X in getting back to me with accurate information so make sure you hear their statement in the last segment.  Another topic Alan brought up was international cooperation with costly missions.  I asked him about Stratolaunch as he was at the initial press conference.  He said “it was like The Band got back together.”  Don’t miss his full comments on this project.  A listener wanted to know about human rating the Atlas V, Blue Origin, and NASA budget issues.  In this context, we mentioned Intrade and Alan told us about the Iowa Electronic Market. 

In the second segment, we talked about orbital fuel depots, SLS again, and the politics of these projects.  Listeners asked questions about Space X and their projects, and then he had much to say on NASA robotic missions.  Toward the end of the program, Alan talked about space leadership & in response to my questions said it has historically come from The White House.  We got a call from Andrew of the Tea Party In Space to advocate Newt’s space policy.  We addressed additional issues for JWST, its cost, its science value, and its possible crowding out Mars robotic missions planned for the future.  Alan referenced Jim Oberg regarding the problems with Russian space hardware and Dave sent in a note about the JWST budget concerns for future astronomy missions and wondered if we were risking too much on one rocket launch.

Guest:  Open Lines with Dr. David Livingston.  Topics:  Space policy programs of the presidential candidates and more.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://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.  Welcome to this 2 hour forty minute Open Lines program. We took one break during the program about 40 minutes into it.  My opening monologue was longer than usual, consuming about half an hour.  I put forth many possible discussion topics but as you will hear on the show, most everyone wanted to talk about the space policy statements by Newt and to a lesser degree Romney.  We held callers to a shorter time on the phone which seemed to work nicely as we had lots of new callers and lots of different input in addition to the Space Show regular listeners/callers.  I will continue holding callers to a shorter time on the phone for future programs based on this experience.  I also put forth some ground rules to avoid partisan politics and to focus only on the space policy of the candidates.  I also made it clear that there would be no character bashing but ideas were fair game.  Most of the discussion regarding Newt’s statement dealt with his having talked about the lunar colony and making it part of the U.S.  Callers kept referencing the Outer Space Treaty (OST) which prohibits territorial claims on celestial bodies.  We talked about property rights and one caller referenced the Northwest Ordinance of 1787 Population Threshold which Newt referenced in his policy comments.  This caller also took us to a discussion of weapons in space, specifically nukes, as part of his comments on the OST.  This led to a discussion and a factual call on why weapons in space are not practical though nobody was advocating weapons in space nor did anyone advocate withdrawing from the OST or modifying it.  As for the Romney comments, some callers had issues with the panel of advisors for Romney and I questioned why DOD was being included in civil and commercial space planning, mission design, etc.  Another caller was physically present at both the Romney and Gingrich meetings so  he gave us a first hand report on what he saw and heard.  Later in the program, a caller referenced some of the gender and microgravity issues raised in the recent show with Dr. Bill Rowe and we talked about the need for a variable gravity research station to answer micro and artificial gravity questions in support of long duration human spaceflight.  While not specifically mentioned by anyone during the discussion, it is important to note that up until the new administration took office, it was national policy for the U.S. to return to the Moon and establish a lunar outpost which would eventually be turned over to commercial interests.  I don’t recall the giggle factor back then but we did talk about the giggle factor which seems to have returned as a result of the Newt comments.  Also, as soon as the program ended, I received a note about an interview by Dr. Jeff Foust on his spacepolitics.com blog with Eric Anderson, one of the key members of the advisory panel on space for Gov. Romney.  You can read this interview at /www.spacepolitics.com/2012/01/29/anderson-romney-would-be-advocate-of-commercial-space.  Again, it came in too late to be mentioned during our program but in my opinion, it is relevant to the OL discussion for today’s Space Show program.  Please post your comments/questions on The Space Show blog per above.  If you want to send a note to any of the callers, do so through me and I will forward it for you if have the email address of the person you want to contact.

Dr. Harley Thronson, Friday, 1-27-12

http://archived.thespaceshow.com/shows/1699-BWB-2012-01-27.mp3

Guest:  Dr. Harley Thronson.  Topics:  “Accelerating the Future: The Importance of Human Achievements Beyond LEO Within a Decade.”  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://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. Harley Thronson back to the show to discuss the existing and future planning for human spaceflight beyond LEO (BEO).  We talked about two recent Space Review articles Dr. Thronson wrote which I believe you will find very interesting.  (www.thespacereview.com/article/1985/1 and www.thespacereview.com/article/1756/1.  In addition, Dr. Thronson discussed the Future In Space Telecon (FISO) series that he hosts every Wednesday afternoon at 3 PM EST.  To learn more about FISO and get on their mailing list visit http://spirit.as.utexas.edu/~fiso/fisowg.html and www.futureinspaceoperations.com.   In our first segment, we discussed the FISO telecons, then we switched to what’s next for human spaceflight (HSF) after LEO or BEO (beyond Earth orbit).  For this discussion, we referred to the two Space Review articles referenced above.  As we learned, there is considerable thought being given within NASA and among others at to what is next after the ISS and how do we start preparing for it.   Dr. Thronson talked about prioritizing what has to be done to move beyond the ISS and LEO.  Also in the mix were mission and even hardware design compromises that may enhance our ability to be ready to fly sooner, not later.  Those involved in this planning are of the opinion that we must compromise and also must fly soon, start something, otherwise we will lose opportunities and drive up costs even more than they will be.  Much of this has to do with being able to capitalize on the existing ISS workforce and those who know how to do space stations and HSF.  If we do not retain these people, then starting over again years later will be costly and will have a huge learning curve associated with it.  The goal of planners and thinkers Dr. Thronson is working with is to be BEO by the end of the decade.  We discussed where to go and here, our guest had much to say about Mars and the Moon, but said Earth-Moon libration points were best for starting out using a stepping stone approach.  Much of the first segment went into detail about these subjects and issues.

In the second segment, we talked about crew safety, using previously built but never used ISS modules as the basis for a BEO station, and compromises that can get us going quicker, not later but not adversely impacting safety.  Michael called in to talk about accidents and inevitable fatalities with HSF and the industry to properly handle them when/if they happen.  Both Dr. Thronson and I had much to say about safety, accident management, and this subject.  Another listener wanted to know when there would actually be work on BEO projects rather than just talking about them.  Dr. Thronson had much about getting started, time lines, mission readiness and more.

Dr. Steve Howe, Tuesday, 1-24-12

http://archived.thespaceshow.com/shows/1697-BWB-2012-01-24.mp3

Guest:  Dr. Steven Howe.  Topics:  space nuclear power for power & propulsion systems, & radioisotope power generators. You are invited to comment, ask questions, & discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com.  Comments, questions, & any discussion must be relevant & 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.  You will want to follow the websites along with our guest:  http://csnr.usra.edu/index.html &  www.usra.edu.  If you are interested in the CSNR 2012 Summer Fellowship Program, you can learn more & apply no later than March 9, 2012  from CSNR at  http://csnr.usra.edu/2012_summer_app2.html.  We welcomed Dr. Howe to the program to discuss space nuclear power.  We started out with an overview of both the Center for Space Nuclear Research & the Universities Space Research Association.  Dr. Howe then told us that they were working on nuclear rockets with the Aerojet Corporation, focusing on a new fuel form away from based on tungsten.  During our discussion, he had much to say about this fuel, its advantages, & its testing.  He also talked about ISP & thrust to weight ratios.  He was asked about testing & we learned they plan on doing ground tests at the Nevada Test Site.  Listen to why their tests will be different from earlier nuclear rocket engine tests & how they are expelling the exhaust into the ground.  You will hear There is no radiation, only hydrogen which bleeds into the rock strata.  We also talked about public concern for nuclear power in space, then we shifted our focus to a nuclear rocket mission to Mars.  Dr. Howe told us about the three year Mars mission but also said with a nuclear rocket a one year mission would be possible.  We also talked about the costs for developing the nuclear rocket as well as the possibility of other countries doing it before the U.S.  Next, we talked about the use of uranium & even the possibility of thorium, including why thorium is not useful for weapons. One listener question asked about the Mars Direct method & insitu resource utilization.  Dr. Howe supported the use of insitu but suggested it for later trips as it might be too risky for the initial trips.  He then described their Mars Hopper project which will certainly interest us all.  As this segment ended, we talked about using the nuclear rocket for going to the Moon & for a lunar & even Martian habitat. 

As we started our second segment, Dr. Howe was asked if QuickLaunch could be useful.  Dr. Dewar sent in a clarification note about U-233 as a byproduct of  thorium & why its a problem for weapons.  In talking about a lunar habitat, Dr. Howe told us about the NASA Fission Surface Power Program (FSP).  We also talked about using the new tungsten fuel for habitats.  He told us about the Nuclear Thermal Mars Sample Mission Study that compared the nuclear rocket to Delta IV launches.  Listeners asked about Vasimr & our guest was asked to clarify for us the differences between nuclear electric propulsion & nuclear thermal propulsion & why the latter is preferable.  Dr. Dewar sent in another note to talk about Y-12.  Later, much was said about plutonium & its pending shortage.  Make sure you hear what Dr. Howe had to say about this looming shortage. Near the end, Dr. Howe mentioned his efforts with Hbar Technologies, LLC, suggesting that possibly using these nuclear advancements for medicine, specifically cancer, might be a driver for space applications. As we concluded, Dr. Howe told us about his books on Kindle & the consolidated all in one book, “Earth Rise.”  Here is the Amazon URL & remember, if you buy it using this URL, Amazon contributes to The Space Show: www.amazon.com/Earth-Rise-ebook/dp/B005LD3LYS/ref=onegialeafou-20

http://archived.thespaceshow.com/shows/1696-BWB-2012-01-23.mp3

Guest:  Dr. Peter Shaver.  Topics:  Dr. Shaver’s boo, “Cosmic Heritage,” the universe, cosmology, consciousness, cognition.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://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. Peter Shaver to the show to discuss his new book, “Cosmic Heritage: Evolution from the Big Bang to Conscious Life.  Dr. Shaver started our discussion by telling us what motivated him to write this book as well as the search for answers to the Big Three questions:  (1) What are the origins of life; (2) What is the nature of life; (2) To understand consciousness.  We talked about the big bang, the microwave background and the early phases of the universe.  We also discussed cosmology & the inter-disciplinary nature of his book, including the fields of psychology, consciousness, and biology.  We talked about the age of the universe at 13.7 billion years.  Dr. Shaver then described the timeline by referencing the Sagan Calendar. I asked him about a section of his book, “Are There Questions That Science Can Never Address?” starting on page 238.  Dr. Shaver talked about taboos and the limits of science. Recurring events or experiences in the natural world can be subject to the scientific method.  A once-only event may not be due the inability to repeat the experiment.  Also, if something is outside the natural world, the paranormal for example, science would not likely be able to address that issue or question. Later, Dr. Shaver was asked what came before the Big Bang.  Here, he introduced us to multiverse theories.  He mentioned the work being done with the Large Hadron Collider and the search for the search for the Higgs-boson particle. Another project he mentioned was the European Space Agency Planck Satellite designed to observe the anisotropies of the cosmic microwave background.  A listener asked about the political nature of science, especially science funding.  Dr. Shaver had much to say in response to this question, including the use of peer review.  Other listener questions asked him about big science projects and their value compared to cost such as the James Webb Space Telescope.  Cognition and consciousness were discussed in the context of his book which addresses the field of neuroscience.  Terry called to ask we will see in telescopes as we get closer to the big bang. Will we still see stars, planets, or just matter in chaos?  Dr. Shaver then guided us through gazing through the dark sky at night and slowly removing from our view the sources of light until we reach the edge of the universe which he referred to as the Near Side of Dark Ages.  Another listener asked if we could actually see the big bang and he talked about the microwave background and fog that we cannot see through.  This brought up the Hubble Deep Field, then Andrew asked if we could use a telescope to see the first light from Earth when it was formed. As our discussion was drawing to a close, we talked about the rate of advancements in science, finding planets in the habitable zone and the future for those wanting to study science or have a science related profession.  Post your comments/questions on The Space Show blog URL above. You can order the book from Amazon using www.amazon.com/Cosmic-Heritage-Evolution-Bang-Conscious/dp/3642202608/ref=onegialeafou-20.

http://archived.thespaceshow.com/shows/1695-BWB-2012-01-22.mp3

Guest: Dr. William (Bill) Rowe.  Topics:  Space medicine issues, magnesium issues, microgravity, ISS experiments, and more.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://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 back to the show Dr. Bill Rowe for updates on his presentations in China and elsewhere, his continued research on the role of magnesium in space medicine, the role of telomeres and gender crew issues for long duration spaceflight including trips to Mars.  During the first segment of our two hour plus program, Dr. Rowe directed us to many of the pages, articles, and documents on his website, www.femsinspace.com.  I urge you to access the pages he directs us to at various times during his talk and follow along with him.  This is important.  In this segment, we talked about the latest telomere research and its application to space flight.  Bill proposed ISS rat experiments and what the experiments should tell us.  He also talked about the role of magnesium deficiency in cells in spaceflight.  He talked about the need to develop a subcutaneous replenishable silicon device/pump to deliver magnesium and explained why this was essential.  Dr. Rowe talked about cardio-vascular issues in spaceflight in the context of magnesium and the overall issues of vascular disease.  This took us into the area of gender lifespan differences and studies showing that an all female crew to Mars might be desirable.  Also in this segment, Dr. Rowe talked extensively about oxidative stress and referred us to his submarine diagram on his website, www.femsinspace.com/Oxidative_stress.htm.  Marshall called in to talk about the ISS and the need for artificial gravity, partial gravity, or 1 G.  Dr. Rowe said 1 G was essential for humans.  Dr. Paul Dear called in from the UK with several questions, including asking about the initiating events for the body to sense microgravity down at the cellular level.  Bill & Dr. Dear also talked about genomic selection for astronauts. 

In the second segment, Dr. Rowe continued his discussion of the first segment topics and his proposed rat experiment regarding telomeres. Many listener calls and emails came in and Dr. Rowe expanded the discussion to the role of calcium for space flight and the calcium/magnesium ratio or relationship.  He was asked why magnesium was not discussed by most human factors space medicine doctors. Dr. Jurist was also asked this question during his call, listen to what they said in response to this question.  Bill talked about exercise routines for spaceflight & said it was a challenge to know the right exercise RX.  Don’t miss his comments on this issue. Near the end, he used Columbus and sailing ships as an example saying we are not ready for long duration spaceflight or a trip to Mars.  Listen to how he and I explained this during the closing comments for the show as I helped Bill phrase his analogy.

Rick Tumlinson, Friday, 1-20-12

http://archived.thespaceshow.com/shows/1694-BWB-2012-01-20.mp3

Guest: Rick Tumlinson.  Topics:  Why Space, space vision, NewSpace, SLS, opening the space frontier.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://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 Rick Tumlinson back to the program for this nearly two hour discussion of space vision, leadership, programming, SLS, advocacy and more.  In hour first 70 minute segment, Rick opened by talking about his ongoing op-ed series in the Huffington Post titled “Why Space?”  So far he has two issues uploaded to the Huffington Post & I urge you to read them.  You can see all of Rick’s articles on the Huffington Post at www.huffingtonpost.com/rick-tumlinson. During our discussion, Rick stressed the need for space settlement and talked about this during the entire program.  Additionally, Rick focused on the big picture space vision throughout our entire discussion.  In the first segment, SLS came up but it was also talked about later in the show.  Rick explained why he thought it was the wrong project for this point in time and had much to say about private industry launch & space transportation systems as compared to government programs.  When asked if he thought SLS could be appropriate as a placeholder, he said no but listen to what he had to say about this idea.  He talked about not picking winners and advocating a common sense space plan.  I asked him for his plan and how to implement it.  He then outlined a plan in several steps during the balance of the segment.  Don’t miss it.  Listeners called & asked questions about the Chinese space program and cooperation and the same with the Russians. 

In the second segment, Rick started us off with a discussion about the Frontier approach for space development.  He also talked about going to the Moon and why, but also about asteroids & Mars.  He said we need to develop the skills and the insitu experience for living & working in space.  Several times he mentioned that on the Moon and Mars we would be living underground due to the radiation.  Rick then talked about space habitats including O’Neil like space stations/habitats.  Several listeners asked about the role of HSF in developing our understanding of the universe, specifically for 2012 and beyond.  John from Atlanta called in to talk about the lack of civility coming from the NewSpace community toward old space.  This produced a spirited give & take with Rick which in a way focused on “guarantees” for the commercial company success as compared to government rocket programs.  John suggested it was a bit risky putting all the “eggs” in unproven commercial company baskets when we know the government launch vehicle will work as long as the program is not cancelled.  Don’t miss what John and Rick had to say.. Toward the end, Rick talked about the Texas Space Alliance & his new organization, EarthLight Institute. He provided us with substantial detail about the EarthLight Institute plans, their website which is under construction,  plus the book on asteroids that he is working on and will be out around the end of the year.  He was asked about his continuing role with the Space Frontier Foundation & the activities of SFF.
