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 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.

Guest:  Dr. Scott Hubbard.  Topics:  Our Mars mission projects from the perspective of our first NASA Mars Czar.  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. Welcomed Dr. Scott Hubbard to the program to discuss his new book, “Exploring Mars: Chronicles From A Decade Of Discovery.”  If your buy the book using the following Amazon URL, Amazon will make a donation to The Space Show/OGLF:  www.amazon.com/Exploring-Mars-Chronicles-Decade-Discovery/dp/0816528969/ref=onegiantlea20.  In our first segment, Dr. Hubbard talked about being selected as the first Mars Program Director after we lost both the MarsClimate Orbiter (MCO) and the Mars Polar Lander (MPL).  He also told us the story of how he got dubbed the first Mars Czar.  His story is fascinating, from how he was asked to do this by then NASA Administrator Dan Goldin to what the Blue Ribbon Panels said about why we lost both MCO and MPL.  We talked at length about the lessons learned from these losses, the review panels, and from the Faster, Better, Cheaper program strategy.  Given Dr. Hubbard’s experience as the program director, I asked lots of questions about getting program approval and keeping that approval over time with Congress.  Dr. Hubbard was most insightful about this process.  Other related topics discussed in this segment included risk, planetary science budgets, private sector companies such as SpaceX, and mission oversight and its cost.  We talked about private missions to Mars and what is referred to as the Holy Grail for Mars missions, a sample return mission.  We went into some detail regarding the sample return mission and Dr. Hubbard let us know why it was so important as well as to outlining a three part strategy for doing a Mars sample return mission.  As our segment ended, we talked about internationalization of our Mars mission programs.
In our second segment, Dr. Jurist asked our guest for some comparisons with the robots versus humans to Mars missions.  You do not want to miss what Dr. Hubbard said in reply to this set of questions.  Doug called in to inquire about cost comparisons for more robots over one human mission.  Doug also raised some interesting points about the sample return mission planning.  I then asked our guest about advocate lobbying for Mars and space policy and if it was effective given his experience with Congress, staffers, and the legislative process.  The value proposition issue came up in this segment regarding both robotic and human missions.  A listener then asked about the focus on space settlement by several advocate organizations and many in the NewSpace community.  Don’t miss what Dr. Hubbard had to say about settlement as a goal, especially when compared to exploration as a NASA goal.  Toward the end, I asked about the follow the water theme throughout his book and why that was so important for the Mars missions to date.  As we learned, the next phase of Mars missions will likely focus on the fingerprints of life, following the signs that may lead to discovering organics or even more. As our discussion was ending, we did talk about finding life on Mars & educational outreach.
