We welcomed Dr. Erik Conway to the show to discuss his new book, “Exploration and Engineering: The Jet Propulsion Laboratory and the Quest for Mars,” JPL history, engineering, Mars missions, and much more all from the historical perspective.  In the first segment of our 1 hour 28 minute discussion, I asked Dr. Conway how JPL engineers did things that led to major Mars exploration breakthroughs.  He cited the Mars Pathfinder mission as an example and the decision to use airbags for the landing.  Dr. Conway took us through the process, the cost benefit analysis of the decision and the role played by budgets, the engineers, policy makers, and others contributing to the mission.  Our guest provided us with other examples as well from other Mars projects and missions.  Listeners asked our guest about human missions.  Here, Dr. Conway had much to say throughout our discussion focusing on the fact that humans are dirty with bacteria, planetary protection is a priority, and there is zero risk or near zero risk for a human mission.  When asked if the Moon required the same planetary protection policies as Mars, he said no though in the early days of lunar exploration, it did.  I asked our guest about the roles played by policy makers and engineers and this resulted is a very interesting discussion. Don’t miss it.  Listener Barbara in Seattle asked our guest about Curiosity cost overruns and how that would be reported on in history.  This led to a discussion about the impact of management and others on the initial design and budgets.  Later, Dr. Conway was asked why JPL had a focus on Mars in the first place.  Doug called in to ask about the humans vs. robot debate for science.  Don’t miss the response to this question by our guest.  Doug also brought up the issue of finding past or present life on Mars and what that might mean for future  Mars missions.  Dr. Conway agreed that probably all sides in the argument of avoiding Mars to avoid contaminating and disturbing life to the opposite perspective will be arguing the issues for a long time to come.  Dr. Conway addressed commercialization and while supporting reduced launch costs said the cost reduction needed to be magnitudes lower than even the lower costs of today.  Dwayne called and addressed planetary protection, then he turned his attention toward asking about the research opportunities at JPL for outside historical researchers.  Erik explained why these opportunities were limited, partly holding ITAR responsible.

In the second segment, Erik talked about the risk versus return on the costs.  He talked about there being almost zero tolerance for accidents and losses with Mars missions and human missions.  He also said the zero risk tolerance for these missions has been a significant cost driver.  Our guest had much to say on this subject with regards to Mars so don’t miss it as it covered most of the second segment. Later in this segment, Jake inquired about the early JPL history and its founders and their impact on the JPL of today.  Penny wanted to know about the Cal Tech-JPL relationship.  Dwayne sent in an email asking about the Faster, Better, Cheaper programs and what happened with the JPL programs using this approach.  This was an interesting way to wind up the show. As we were ending we learned that Goddard has no historian so their programs are not being recorded or document.  I sked Erik the difference in JPL and the APL.  Note how he explained the difference between the two labs, their risk tolerance, and decision process.

We welcomed Brian Altmeyer to the program to discuss his Oct. 6, 2014 Space Review article, “The Strange Contagion of a Dream: How Space Visionaries Hijack Governments to Change the World (see http://www.thespacereview.com/article/2611/1). During the first segment of our 1 hour 27 minute discussion, Mr. Altmeyer introduced us to the background behind writing this article, how he got the idea for it, plus he explained the overall impact space visionaries have had on him and his interest in space development.  Our guest took us back in time to the V2 program, Von Braun, and the politics of beating the Soviet Union to the Moon.  He made the case that both the Soviet Union’s and the US space program fed off each other in the form of competition to not only develop military space resources and ICBMs, plus our civil space programs as well.  I then asked our guest if he thought competition with China over their lunar and long range plans would result in a similar push for civil and commercial space.  His response was very interesting.  Ellen in Portland sent an email suggesting we did not have inspirational or effective leaders today like we had with Von Braun and others.  Brian disputed that and made reference to Elon Musk at SpaceX several times during our discussion.  Gerald Driggers called to talk about the impact of the International Geophysical Year on our early program.  Gerald worked in the early space program & had much to say about the main space personalities of the time along with the early rockets.  Our guest was asked about vision and Mars One, again he brought up SpaceX, and then he talked about exoplanets.  I asked him about the second to last paragraph in his paper regarding leadership issues and many waiting or expecting a new leader to come on the scene in a future election.  Don’t miss his comments on this issue.

In the second segment, Brian was asked about space budgets serving as a limiting factor & if SpaceX was carrying too much of the burden for our moving forward with space development.  Listeners asked him about sustainable space projects inspired & pushed by advocacy.  Do the projects continue or eventually die off?  Allison sent in a note asking our guest why we even needed HSF.  For his response, he cited reasons often provided by Elon Musk when he gets this question or one like it.  Near the end of the program, Ron emailed our guest to challenge his visionary outlook by asking if he had considered the reality of applying  human medical factors, engineering realities, orbital mechanics, & the known science for rockets & human spaceflight regarding the type of visionary statements made by Brian during the show.  This proved to be an interesting discussion as Brian said there were two ways to resolve such issues.  One way would be through testing and incremental progress to resolve or mitigate problems and the other way would be to just do the flight and sort of learn on the job, realizing there would be lots of casualties but at least we would be flying and learning.  I asked our guest if he was dismissing the known engineering &science including medical science.  He said he was not but clearly he preferred the second approach to problem solving. What do you think?

Please let us know by posting your comments/questions on TSS blog above.  You can reach our guest through me or the email address he provided at the end of his Space Review article.

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.

We welcomed back Dr. Jeff Bell & was at his best for blunt talk, specifically the need for a winning rational for human spaceflight (HSF).  For those of you new to Dr. Bell, hold on tight for a ride that will likely be upsetting.  During the first segment of our 1 hour 58 minute program, Dr. Bell started with saying he was pessimistic over the future of human spaceflight.  In fact, this was an overriding theme throughout the full discussion.  He said it was more than just not properly telling the story either by NASA or space advocates.  He said there was no winning rational for the need or the urgency of HSF.  While he was pessimistic on HSF, he was just the opposite on science, robotic, & unmanned missions which he said were doing well & in a class of their own.  He also talked about the success of satellites & that part of the commercial industry.  Listeners challenged him during the show.  He got several emails regarding space settlement which Jeff addressed in terms of his perspective on HSF.  He also nixed the idea of leaving Earth as a safety valve for when Earth might be destroyed by an incoming NEO.  This led Jeff to talk about planetary defense.  Tony called with an idea to keep a Martian settlement from freezing at night, a point Jeff talked about re Mars settlements.  A listener asked about radiation & magnetic fields.  Jeff said the atmosphere was more of a screen for Earth, again in a discussion about lunar & Martian settlements.  Jeff talked about Orion & SLS, various ideas for Mars missions & the NASA asteroid mission.  I asked Jeff what he was positive about & he replied the Russian space program & SpaceX with Elon.  He then spoke about some of the Russian programs he follows.  He was asked about space tourism & suborbital flights, then he spoke about SpaceShip2 problems, hybrid engine issues, Richard Branson & more.

In the second segment, he had more to say re SpaceShip2 & Branson.  Next, he was asked about space debris cleanup ideas being skeptical of them.  He was also skeptical of propellant depots.  He spoke about small boosters costing much more than using one large booster.  Pooley called in to support everything Jeff was talking about.  Dr. Bell was asked about Dream Chaser.  In general, Jeff was very critical of lifting bodies & their CG problems.  Listeners asked for his assessment of Inspiration Mars & Mars One which was not positive.  In his closing comments, he said HSF was probably mature & needed radical new technologies to make it cheaper & feasible.  I told him he should come back on the show, invite only callers & emails suggesting radically new & different technologies & he could assess the ideas.  Dr. Bell agreed to do that so watch the newsletter for this upcoming program.

We welcomed Dr. Bruce Damer back to the show to discuss his 3D real time simulations, the human NEO mission study & design project, planetary protection, astronaut safety and much more.  Here are the websites Bruce mentioned on air:  www.damer.com, www.levityzone.com, and www.digitalspace.com.  In addition, later in our discussion Bruce also talked about a Dave Brody YouTube video that was relevant to our discussion.  You can find this video at www.youtube.com/watch?v=UAm9escDxu0.   In the first segment of our 1 hour 31 minute discussion, Dr. Damer talked about the renewed interest in asteroid projects within NASA and by others, especially after the Russian event a few months ago.  Dr. Damer had lots to say about a recent meeting he attended at AMES, budgets, and the renewed interest in the subject.  Listeners started asking him questions early on, including questions about docking with an asteroid with little or no gravity, the use of aerogel to collect micrometeorite particles, plus the recently announced commercial asteroid missions being planned.  Robots versus humans came up many times, Curt asked about the use of the ISS, prioritizing budgets, lunar basis, etc.  Doug called in regarding the incremental approach Dr. Damer had mentioned or as referred to in our discussion, stepping stones.

In the second segment, we talked about the designs on www.digitalspace.com and the Brody YouTube video per the above URL.  Also discussed was planetary protection with the use of the gravity tractor. We talked about needed lead times to interfere with a potentially dangerous NEO that might be headed for Earth,  then more questions came in about a lunar base and what Bruce thought to be more important, the lunar base, Mars, or the NEO mission.  Doug called in to discuss and challenge some of the mission planning ideas Bruce put forth, especially around trial and error, R&D, incremental development and long time lines.  Near the end, we talked about human spaceflight safety & the ideas put forth by Rand Simberg & others that we needed to take more risks, not make safety the extreme priority.  Bruce had many relevant & important comments on this subject.  Final comments focused on 50-100 years in th future with asteroid & other capabilities but only if we keep moving forward today.

We welcomed Robert Sackheim to the program to discuss NASA, commercial space, the current state of rocket propulsion and advancements in the field.  During our first segment of this 1 hour 47 minute discussion, Mr. Sackheim talked about his background and experience at TRW, NASA MSFC, and his current consulting.  I asked him several questions about the current state of rocket propulsion. Bob had much to say about this, focusing on chemical rocket propulsion, satellite propulsion, electric propulsion, and the need for nuclear propulsion.  He talked about booster rockets, various rocket stages and their propulsion, rocket engines, and even SRBs.  Several questions came in asking him if we had the current technology for HSF to Mars or even the Inspiration Mars flyby mission talked about so much in the recent press.  Listeners wanted to know if our current levels of propulsion were up to the task.  After a rather thorough propulsion discussions, Bob turned to commercial space, lowering total space mission costs, regulatory policy, and commercial spaceports.  He also talked about budget issues and raised the question a few times as to why ten NASA centers were needed given their often overlapping, competitive, and duplicate work.

In our second segment, commercial space took the lead with a discussion on public/private partnerships & the belief that Americans can do anything if we set our mind to it, including space travel.  Of course here the problem as we know lies in leadership and today it appears that leadership in space & other areas is sparse at best.   Bob then focused on geo satellites and the increasing development and capabilities applicable to cubesats.  HSF came up for discussion as did the robotic missions. You might be surprised by what our guest had to say about HSF.  Other issues in this segment included the lunar space elevator, the congressional and NASA track record in canceling ongoing projects & taking lessons from history, SSP, & ways to reform & move NASA forward.  Bob spoke about evolving toward the old NACA model.  I asked about the impact of space advocacy from his perspective given his leadership experience and past positions in leading organizations and projects.  We also asked him about space tourism and hybrid rocket engines. He had much to say about hybrids, don’t miss the discussion.  Bob talked about the Falcon rockets, testing including static fire tests, and SRBs as related to the Constellation project and safety.  Toward the end, our guest was asked about NewSpace, fuel depots, & cryo transfer.  For closing comments, he talked about commercial space being the way to go & the path to our space future.

Guest:  Les Johnson.  Topics:  “Going Interstellar: Build Starships Now!,” and interstellar propulsion & advanced propulsion concepts.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, https://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 started our discussion by talking about interstellar travel, his new book, “Going Interstellar,” and advanced concepts, both for NASA and outside the NASA mindset.  Please remember that if you purchase this book from Amazon using this link, Amazon will make a contribution to The Space Show/OGLF:  www.amazon.com/Going-Interstellar-Johnson/dp/1451637780/ref=onegiantlea20. Les told us that both he and his co-editor, Jack McDevitt, had very little trouble getting the authors to contribute to the book which consists of a series of short stories from well known science fiction authors plus scientists.  There is a focus on the plausible and grounded physics so that the sci-fi is rooted in actual physics.  Les took several phone calls wanting to know about advanced concepts and propulsion at NASA and in general outside of NASA. We spoke about many concepts including solar sail technology, nuclear electric propulsion, the fission fragment rocket, faster than light (FTL) travel, antimatter, & the types of possible starships that might be used, plus the time intervals to travel from point A to point B.  We talked about the challenges from the laws of physics, political leadership, funding, & timelines. Les said that barring the discovery of new physics which he is not optimistic about at this time, he does not think FTL travel will be possible. When I asked about the discovery of Higgs-boson as an example of discovering new things, he talked about the discovery of that which is predictive as compared to something entirely new and unknown.  Other topics in this segment included artistic license in sci-fi writing, the role of physics & the imagination, & even questioning the possible role of ET in contributing to advanced propulsion concepts.

In our second segment, Marshall was our first caller & we talked about the French nuclear program, fusion, & the large ITER reactor program.  Les went over many of the fusion energy challenges & we talked about some fuel issues.  Les then told us about some of the future books he is working on & then he had more to say about solar sail technology which is his preference at this time for robotic interstellar missions.  We took a call about the huge Atlanta, GA sci-fi conference, DragonCon ( http://dragoncon.org) as Les will be a featured speaker there this year. As the program was ending, we talked about HSF NASA infrastructure, the Von Braun model for spaceflight, and more about the specific stories in his book.
