We welcomed back to the program Dr. Mike Griffin.  During the first segment of our 90 minute discussion, Mike talked about human spaceflight (HSF) and the commercial space market.  He said exploration would be a government project or at least with government in the lead, especially if the commercial market was not there.  He threw water on the argument that our space policy was budget driven.  Instead, he talked about it being based on choices we make. It was not and is not about the money.  His comments throughout or discussion on this topic supported his argument.  He even said the cost of space for the U.S. taxpayer was around 15 cents/day.  This discussion evolved to one on the importance of leadership which we agreed was in short supply today.  Included in this discussion was Mike’s vision for our space policy & program, plus he explained its importance and value to our nation both today and for the future.  He spoke to the issue of what society wants and the choices it makes that shape our future.  Space should be part of our national policy debate and hopefully such a debate would enable quality choices to be made that keep us on the leadership edge with all nations.   Mike was asked who he thought would be next on the Moon and he said China.  We also talked about the private sector taking us back to the Moon with HSF.  He said that the private sector could do this, capital was not an issue, but for the private sector to do it there needs to be a closing of the business case which he did not see at this time.  SLS John called in & asked about space advocacy diversity which he said seemed to be at war with NASA & whatever the program of record might be.  Mike had much to say about this, especially about inefficiencies in government organizations and projects.  He also said if the private venture or industry cannot make money, then it should be a federal project. Many times during our discussion he said that there are things that a society should do just because they are hard & they don’t have to look good on the balance sheet.  John also asked about the RD-180 engine, Mike offered us his conclusion as to why we should be a new version of the RD-180 so that we do not continue being dependent on Russia for space related hardware, etc.  Later, he was asked about cislunar space development which he said should be a public enterprise.  He cited many examples and models supporting the public development of this important space infrastructure.  SLS was discussed.  Mike very clearly articulated the case for SLS today and again repeated that SLS future missions are about choices, not the budget.  Don’t miss his comments.  As the segment ended, Randy emailed a question asking for the rational & silver bullet for HSF.  In my opinion, Mike gave an excellent response to this question so don’t miss it.

In the second segment, Mike got some questions about NASA doing more R&D and even forming a NACA-like division or program.  We talked about NASA R&D, the need for a NACA-like program and more.  Dave, our caller, commented on leadership, then Bill in Denver emailed in a question about using fuel depots and smaller launch vehicles rather than heavy lift vehicles like SLS.  Again, Mike had much to say about heavy lift, including that while possible to do smaller vehicle launches., the numbers don’t pan out for efficiency.  You need to listen to this full discussion which also addressed some bogus assumptions regarding inefficient heavy lift decision making.  Nuclear propulsion and Vasimr came up, , then we again focused on vision that takes on big challenges because we can!  More was said on lunar colonies evolving to longer BLEO missions plus cislunar commerce, especially cislunar cargo missions.  Another listener asked about being dependent on the Russians for HSF to the ISS and if shuttle was retired too early.  Mike talked about having wanted to fly shuttle at a minimum rate annually until a new vehicle was operational.  We talked about the role of the congress and White House as compared to the role of the NASA Administrator.  Later, we talked about the role of public support and individuals petitioning congress on space policy.  Listen to his story about the Hubble repair mission.  I even asked if poorly written and fantasy driven letters to informed staffers helped or hurt the cause.  Listen for Mike’s response. In summary, Mike said his wish was that people would share is view that there are important things for society to do but that don’t look good on a balance sheet.  In the end, he said he was optimistic that his positive views on space would prevail and that when policy makers realized that China was going to put people on the Moon and what that would mean for the US, it would not be allowed to happen.

Welcome to this two hour open line discussion covering a wide range of space topics.  During the first segment which was half an hour, I introduced the program and some possible topics, plus I spoke about having attended AIAA Space 2014, the SmallSat 2014 Conference which was held the same time as AIAA, and I referred back to my having also been at the NewSpace 2014 conference.  Some possible topics of interest for discussion included a recent news story about astronauts usage of sleeping pills while on orbit.  Nobody seemed interested in that topic as it was not discussed during this program.  I also noted the huge gap between those working SLS or having an interest in it and those on the side that hate it and think it’s a huge waste.  As I said, the gap was wider than the Grand Canyon with no signs of narrowing.  This issue was raised during the second segment of tonight’s program.  You can read Duane’s article on the lessons learned astronaut panel I mentioned on air at http://www.aiaa-space.org/Forum.aspx?id=24589.

We paused for a short break and we opened the second segment with a call from John in Ft. Worth.  John remained on the phone for quite some time and we covered lots of topics.  Initially, SLS John, as I like to refer to him, went over his SLS place holder theory again.  We did spend lots of time talking about SLS, the gap between supporters and haters of the project, its operational plan, congress, and more.  We also talked Falcon Heavy which John suggested was potentially less real than SLS though I countered that thought.  We talked about the RD-180 rocket motor problem, and I told him & the listeners about some of my AIAA discussions, interviews including my breakfast with Dr. Mike Griffin & Frank Van Rensselear of Schafer Corp.  We also talked Dream Chaser and the press conference SNV held at AIAA, plus I talked about my interview with Larry Price, Deputy Director of Orion.  John said his real interest in space was advanced propulsion, specifically nuclear. Somehow our conversation ended up talking about Area 51 and the Clinton era lawsuit against the government by workers exposed to toxic materials.  As soon as John got off the phone, Dwayne called in.  He clarified the Area 51 story for us as well as the old litigation that the workers won but then Pres. Clinton used an Executive Order to overturn the court decision.  Dwayne also spoke about 3D printing in space and the recently concluded NRC 3D Printing In Space(http://www.nap.edu/download.php?record_id=18871  note you may need to open a free account to download the report for free).  There are also lots of news stories about the report should you care to research it.  We talked about 3D printing in space, how it might be used, and the possibility of a later metal printer in space.  Dwayne then spoke to the old Coke and Pepsi wars in space several years ago and he addressed the gap with SLS supporters and those that are against it.  He said it was a huge gulf and that he thought both sides may have less than a firm grip on reality regarding SLS.  In addition to the two calls, we fielded an email from Doug who brought up space settlement, the value of attending space conferences, and the commercial crew down select process.  Tim was our last caller and he brought up SLS again, we talked about the congressional candidate on the independent side in the Huntsville district, Mark Bray in that Mark works on the SLS project and that it would be interesting to know his space policy views since he might win the congressional election.  Tim also mentioned a article about Elon Musk in the NextBigFuture.com re an eighty thousand person Mars City by 2040.  You can download the article at http://nextbigfuture.com/2014/08/elon-musk-timeline-and-extrapolation-of.html.  The final email was from Joe in Houston wanting to know the NASA down select process & who might be responsible for it.  I could not answer his question but please, if any listeners know the answer, post it on the blog.

As always, please post your comments/questions on TSS blog above.  You can reach any of the email listeners or the callers through me.

Welcome to this 2 hour 11 minute Open Lines Show.  As we started our first segment, I made several announcements including the return to action for the Space Cynics blog.  This time we will be accepting guest editorials.  Watch for the guidelines/rules for guest editors and those submitting comments to the blog.  Once you see the guidelines/rules on the top blog menu bar, Space Cynics will be officially back. See http://spacecynic.wordpress.com.  I also talked about a recent NPR interview with the inventor of the Super Soaker water gun who just happens to be a top guy at JPL!  I’ll make an effort to invite this person to the show.  Our first caller was from Scott who wanted to talk about and promote his Droid platform app for orbital speed calculations.  If you are interested in downloading this app to your Droid device, search in Google Play for “Orbital Speed.”   Scott described his app and how it worked and since there was some history re the app and the Charles Pooley Microlaunchers book, that came up during the discussion.  This was probably the dominant topic in the first segment.  Pooley did call in regarding the app and the references to his book, but Charles, in addition to promoting Microlaunchers as he usually does, also spoke about himself as the SPACE Heretic.  You can read about this at the tiny URL goo.gl/vo7Ux7 (cut & paste to your browser or use the full URL http://www.linkedin.com/today/post/article/20140620023828-9942227-charles-pooley-heratic?_mSplash=1).  During this segment, we also talked briefly about hybrid rocket motors and specifically about escape velocity.  I read an email from B John in Sweden suggesting that going to the Moon or Mars was and is counterproductive for our HSF program.  I asked for listener comment but unfortunately this topic was not picked up by the listeners.  Perhaps some of you listening on archives will post a blog comment about B John’s ideas.

In the second segment, John Hunt called in to talk some more about escape velocity and the formulas for it.  He then asked a series of question about science and STEM education.  I shared what I knew about the topic but we were hoping for teachers or others involved in this field to call in with more information.  Perhaps those of you working in these fields can post some detailed comments in response to John’s questions on the blog.  We had several emails about American public participation for a better HSF policy and for influencing policy makers and Congress for space policy.  The email questions seemed to think some level of American public participation was needed but that the pressure in numbers was not there compared to non-space issues receiving funding.  Also, most thought that the next election was actually the focus of Congress so without the numbers and pressure pushing for this or that policy, other projects get priority funding.  John called back to talk about the need for competition and the lack of it.  Near the end, I read a series of emails with a space advocate saying those that disagreed with him on specific issues were wrong, uninformed, etc. I asked listeners what they thought of this my way or the highway space advocacy mindset.  John did talk about the upcoming NASA down select process and we both thought for sure SpaceX would be selected.  John then said NASA and the public program lacked vision but SpaceX had a vision.

Post your comments/questions on TSS blog per the above URL.  If you want to reach any of the callers, send your note to me and I will forward it to the person of your choice.

We welcomed Professor Henry Lambright of Syracuse University to the show to discuss his excellent book “Why Mars: NASA and the Politics of Space Exploration.”  During the first segment of this 1 hour 33 minute program, Dr. Lambright introduced us to his book and what prompted him to write it.  Dr. Lambright then described three main motivating factors for having our Mars program starting with before NASA with the belief and cultural components suggesting some sort of life on Mars.  Next as a motivating factor dating back from the Von Braun time frame of humans going to Mars.  His third motivating factor had to do with political issues and competition.  Since we were talking about the possibilities of life on Mars, I asked our guest about Viking and the more recent pronouncements by Dr. Gil Levin who has been on TSS several times over the past few years.  Later, Dr. Lambright had many good things to say about our science and robotic program but said our human spaceflight program was in disarray.  Dr. Lambright got several listener emails & phone calls.  He was asked for the WHY behind human spaceflight and that led to a discussion about Big Science. I asked him to define Big Science which he did.  We talked about the NRC Pathways HSF study, then our guest talked about triggers leading to big events and progress, plus the more typical method of moving forward which he called slow evolution.

Jumping forward to our second segment, we talked about the Clinton years in the 90s for policy, Mars Observer & how that loss was turned into a plus for our Mars policy.  Other topics included astronaut risk taking, the void in leadership for space, Mars, and things in general.  Doug called to consolidate all the motivating factors and issues to just one, the need for more money.  He made a good case for this consolidation.  We also talked about the challenges for getting alternative theories seriously considered by NASA, Congress, and policy makers.  The NASA to NACA suggestion came up, we talked about the privates taking over LEO with NASA focusing on BLEO & advanced technologies.  As the program was ending, I asked our guest about the Syracuse student interest in space and Mars, plus our guest left us with an important closing comment.

Please post your comments/questions on TSS blog. If you want to reach Dr. Lambright, you can do so through me.  Finally, if you buy his book from Amazon, do so through the OGLF Amazon portal so that Amazon will contribute to The Space Show.  Instructions are in each archive write up and on the blog, plus both The Space Show and OGLF websites.

Welcome to this 2 hour 1 minute program.  In our first segment, we started with the first caller, Richard Easton who told us about the passing of his Dad, Roger Easton, the father of GPS.  Richard has been a guest on the show several times &we were most fortunate to have Roger as a guest as well several years ago.  We took this opportunity to honor Roger Easton & talk about the early days of Roger’s timing work which formed the backbone of GPS.  Richard went through some of the early history with us as he has done on previous shows. I urge you to listen to this call plus go back and listen to Richard’s earlier shows, including his first one when Roger was with him. You will hear oral history at its best & from the major scientist/engineer who brought us GPS.  After Richard’s call, we took our first break.

In the second segment, I read a NASA PR announcement about the successful recovery of Dragon bringing back 3,500 lbs. of cargo from the ISS.  Congratulations to SpaceX and NASA!.  John from Ft. Worth called to talk about the U.S. sanctions on Russia regarding the Crimea/Ukraine, the Atlas 5, the RD-180 engine and various straggles that might unfold for the ISS.  John was asking thought provoking questions which neither of us could answer but we do know the situation is largely political rhetoric and posturing right now but could easily change.  I asked John if he thought we might fast track the development of HSF and Dragon.  As he said, we wait and see.  Next, I took a very short break to return with my attempt to respond to the questions about Russia, the ISS, and sanctions asked by Kelly in his email which I read on air.  Our next caller was first time caller John from New Jersey who took us through to the end of the program.  John’s call was an excellent one & I urge you to listen to what he had to say.  We talked about the old shuttle policy, the possible use of depots, lunar settlement & using the Moon for training and experience to go further out in space.  We also talked about Mars and asteroid mission, then the issue of leadership came up regarding policy & in particular, space.  Like so many of us frustrated by our current situation, John was unable to find answers to how to advance policy.  I asked him if the militarization of space by another state actor might be a driver for the type of space activities we had been talking about.  He did not think so but listen to his answer.  One of his favorite comments  was to the effect that “we are having Star Trek dreams in a wagon train universe!”  Prior to ending our program, I went over our upcoming Space Show schedule.

Please post your comments/questions on The Space Show blog above.  You can reach any of our callers/participants through me.

We welcomed Howard Bloom back to the show for this two hour 6 minute complex space policy, leadership, commercial space and more discussion.  During the first segment, Howard worked us into discussions about space and pop culture, space leadership and policy issues, commercial and private space issues, and the SLS as representative of extreme pork taking down the space program.  This conversation included many side tracks including space art for inspiration, Von Braun, Chesley Bonestell, and more.  We talked about The Space Development Steering Committee, their focus on private space as well as space solar power (SSP).  As you listen to this program, you will realize this is not an ordinary Space Show discussion on these topics as Howard brings to us very unique and very broad important perspectives with important information.

In the second segment, Chuck Lauer called in to talk about the Darpa XS1 suborbital program and his company submission.  Later, Howard talked about Dragon and Cygnus plus the significance difference between the two.  He advocated for fuel depots and space infrastructure.  I asked Howard about a timeline for realizing the development/implementation of the project he was talking about.  He also talked about the ISS, Mars, Phobos, and L1.  Near the end of the discussion, Howard talked about his two Kindle books available on Amazon, “How I Accentually Started the Sixties” and “The Mohammed Code:  Why a Desert Prophet Wants You Dead.”

Please post your comments/questions on TSS blog.  Howard provided his social media and email address during this show for contact and for joining The Space Development Steering Committee.

We welcomed Bob Zimmerman back to the show for this two hour discussion.  Bob started the first segment with an overview of commercial space progress to date in 2014 which includes Space X Falcon 9 launch, Orbital’s launch to the ISS, the recent Virgin Galactic demo test plus other events.  SLS came up again and unfortunately took up time throughout the show.  As you will hear me say, I am sick of the pro and anti-SLS comments on the show and really need an SLS break as I imagine most listeners do as well. Unfortunately, callers and email questioners kept bring it back to our focus and Bob was not shy on commenting on SLS as he wants it cancelled.  We talked some about Virgin Galactic and XCOR, then I asked about Dream Chaser given the news it has been seeking international partners to continue the project.  Bob was next asked about the Chinese policy and their lunar lander.  He started comparing the Chinese program of today to the early Soviet Union program and suggested that like all space programs, they will make a significant contribution to changing the culture of the country.  We talked about the new Omnibus 2014 Budget Bill before congress and the increases to NASA, planetary science, commercial crew and more.  As we neared the break, Bob in Berkeley asked Bob the guest to opine on Inspiration Mars and Mars One.  Doug from S. California called with multiple questions before the break, starting out asking about Bob’s comments on the negatives for taking government money and wanting to know if that applied to Space Act Agreement recipients.  His last question directed to Bob and me was based on our being part of the space media and about influencing policy, culture, programs, etc.  Bob’s and my response continued into the second segment.

During the second segment, Trent chatted in from Australia, then Dave called in from Chicago to asked about the J2X engine.   Bob and I talked some more about making a policy impact, then I asked Bob for key issues that will emerge for the balance of the year.  He talked about Russia competing with private companies, HSF and Dragon, astronomy, ground based telescope improvements, and NASA science programs.  At the end, I asked about the new mission for Kepler Space Telescope to have it continuing doing useful and productive research for the rest of its life.

We welcomed Dr. Jim Logan and Dr. John Jurist to this special 2.5 hour Space Show classroom in-depth discussion on space radiation. We focused our discussion on deep space, Mars, the Moon and BLEO missions. Note that on both The Space Show blog (see above) and The Space Show Classroom blog (http://spaceshowclassroom.wordpress.com),  Dr. Jurist has a Power Point presentation on radiation.  During the program, our guests referred to specific slides that you will want to check out.  In our first segment, Dr. Logan started out by telling us about his interest in the subject, why he has been writing a paper on the subject for publication, and how this Classroom show came about.  He cited our short duration spaceflight experience, the Apollo missions, Space Shuttle flights, and then how things started to change when we had six month ISS visits.  Dr. Logan also made it clear that space was not a benign emptiness type of environment.  He said the reality was that interplanetary space was a sea of disruptive ionizing radiation wrecking havoc on biologic systems.  We moved forward in our discussion from that point.  We talked about the findings of the MSL RAD instrument regarding radiation on the way to Mars and on the surface of Mars.  Both John and Jim spent some time putting the RAD numbers through analysis to let us know what this means for human missions to Mars.  We talked shielding, possible materials, passive and active.  We talked extensively about water and the use of hydrogen as well for shielding.  Our guests addressed the two types of radiation, the GCR (galactic cosmic rays) and the CME/solar flare.  Here, John suggested listeners look at his slide 13 as we talked about protons and neutrons.  Jim said there was no magic bullet and talked about shielding effects of Earth’s atmosphere.  Pay attention here as Jim introduced us to the  RP scale.  For being on the surface, he said nothing less than RP100 would suffice.  For the vehicle, an RP5 was required.  John introduced us to career limits for radiation for men and women astronauts of different age but the career limits are for LEO and not BLEO.  BLEO limits are expected to be more restrictive when made public in April 2014.  Earth Mars transit times were discussed, especially in the context of Brian’s email that suggested a 180 day transit time.  Both our guests said that was unlikely with chemical propulsion and all of us again stressed the need for nuclear thermal propulsion.  Microgravity was talked about, especially in the context of side effects due to the radiation environment.  Jim then brought up the EVA subject and spacesuits.  Briefly, Jim said that quite possibly the ISS construction represented the zenith of EVAs which may become a thing of the past.  Don’t miss why he said this plus his description of serious spacesuit limitations.  We talked about life support to Mars and here Jim suggested we should use Open Loop! Again, listen to the rational behind this recommendation.  Don’t miss what our guests said about theories & movies making it sound easy to go to Mars and that the radiation would be nothing more than just a few more cigarette packs a year.  Our last topic addressed informed consent issues.

In the second segment, I asked our guests for a readiness timetable were there sufficient funding and technology advancements.  I also inquired if Russia, China, and others assessed the radiation risks in a similar way to the U.S.  We then talked about radiation and space pregnancy, fetus development, birth, and informed consent for the fetus, a baby, and a child under 18.  Ethical issues regarding child birth and space pregnancy were talked about as well.  Curt had sent in email questions which our guests answered, especially about drinking irradiated water and microgravity DNA damage & what this may mean for radiation effects.  Next, I asked Jim and John to tell us their 2-5 steps for the start of designing a Mars human mission.  Jim went first and listed Day 1 and Day 2 activities, John listed his top three priorities which were different than those suggested by Jim.  Don’t miss this discussion as its very instructive as to how to do or at least start mission planning for a human mission BLEO.  Roger sent in a question asking if the crew should be senior citizens since they have more resistance to radiation.  Don’t miss what our guests said about this idea.  It may surprise you.  Our next topic was would going to Deimos be easier.  Yes, it would but it would be a very different kind of human  mission.  Jim had some great comments about Mars gravity.  Briefly, he said it was the “best.” Later, when asked to compare the Moon and Mars, our guests said lunar radiation was worse than Mars.  Also, the Mars atmosphere does provide limited shielding while there is no such thing on the Moon.  Jim had earlier talked about a sphere being the perfect shape for an interplanetary spaceship.  Shelia emailed in wanting to know if heavy lift made a difference and if the sphere was so good, why were capsules being used? Don’t miss the response.  We then talked about the complexities of rendezvous and docking, especially in the context of fewer launches (heavy lift) as compared to many more launches (smaller rockets).  Near the end, I asked our guests if either thought our nation, the public, NASA, our leaders and politicians were sufficiently motivated to do a human Mars mission.  Jim did not think so and had much more to say in reply to this question.  John was more pessimistic.  Both thought it was more likely that the private sector would mount a human Mars mission rather than our seeing a government mission, but raising the needed capital might turn out to be a show stopper.  The three of us then talked about what it was like growing up in the 40’s, 50’s, and 60’s as compared to today.  John and I (John is a bit more than 2 years older than me) were probably more harsh than Jim in our assessment of today, but we all realize that the younger generations will be taking us to space, building the next smartphone and more. I talked about my visits to Google, Apple, SpaceX, etc. and the excitement in the air in belonging in their work forces which does not seem to exist with NASA. This opened the door for Jim to put it on the line about his NASA experiences and the potential opportunities providing NASA can somehow reorganize.  He did not think the type of reorganization he was talking about would happen.  Both our guests left us with excellent takeaway points and concluding pearls of wisdom.

During the first segment of our 91 minute discussion with Mike, we talked about the lack of a coherent national space policy and how best to use tax payer dollars for the public good.  Mike discussed the fact that there was no credible alternative to the RTM program, no clear path to any set of discernible goals.  I asked Mike about NASAs asteroid redirect mission.  He did say it had interesting potential and it was better than nothing but as listeners agreed, it was not a grabbing and inspiring program.  Listeners asked Mike about Constellation which he said was a space system architecture.  We talked about a lunar base and access to Mars.  I asked Mike about the public’s interest in space & you don’t want to miss his response.  Daniel brought up budget issues, commercial ventures, and the current administration.  We also talked public/private partnerships and multi-year programs and policy challenges.  Mike was asked about the VSE and bipartisan support though Jon emailed in his disagreement on that issue.  Mike talked about goals as being important to congress and the need for an effective policy to have bipartisan support.  Mike was asked about the ISS and the potential for discovery and we he responded to a listener question about the mass needed in orbit to support a lower mass on the Moon.  The ratio is 10::1. 

In the second segment, June asked about economies of size in launch vehicles and heavy lift.  Barbara emailed in about a COTS like program for HSF.  Trent called from Australia to inquire about Stratolaunch.  Doug called to ask about cislunar development and what a program that supported that development might look like.  Mike had much to say on this subject, don’t miss it.  We talked extensively about the role of government and the private sector, including government subsidies.  A listener talked about scientific discovery and serendipity.  John asked about the Ares 1 vibration and solids in comparison to liquids for safety.  John in Ft. Worth asked Mike about SLS and Orion as a capabilities holding program and Mike agreed.  The idea is to maintain capabilities until the time they can be used.  During the entire program, I asked Mike about his public service, how he dealt with attacks and criticism, and how he got his interest in space.  This is an important discussion.
