We welcomed back Drs. Jurist and Logan to this CLASSROOM program which addressed many issues of the 2 hours 1 minute broadcast.  We started out with Dr. Logan discussing fantasy or magical thinking going back to the influence of a 2001 Space Odyssey movie poster had on him.  From there, Jim went into a discussion about Constellation, then the Space Shuttle as examples of what he was talking about and as to how programs and faulty ideas grow and multiply.  He also talked about life science challenges.  A listener asked him about space politics, then Dr. Jurist offered additional examples with a focus on air launch.  Our guests then discussed thinking based on agendas and ideology.  One of the keys suggested for breaking out of this magical thinking mode involved surrounding yourself with really smart people.  Later, I offered my perspective on that given my own experiences early on in Space Show time and before.   Both Jim and John said a few times that one needs to know his or her limitations.  Our guests then talked due diligence with assumption building, fact checking, disclosures, and more.  I relayed my own wake -up call experience due to Al Zaehringer who was on the show several times years ago before he passed on.  Before the segment ended, Jim told us a story about the Wright Brothers and their Wright Flyer experience.  In our second segment, John Hunt called in to talk about Jim’s Space Shuttle comments.  This was a lengthy discussion with John, Jim, & John Jurist.  Jim talked about advantages with Saturn V including economic advantages over shuttle to LEO.  Subjects of reusability came up along with issues of getting a specific payload to orbit which our guests suggested advocacy often glosses over with facts and trades for payload mass fractions involved in reusability.  Dr. Logan brought up and discussed what he called NASA Brinkmanship Strategy.  Jim then talked about the reality of sending payloads to the ISS using shuttle.   Trent in Australia sent a message about magical thinking with Mars One.  Our last caller was Alan from St. Louis who said John and Jim were too negative in their discussion.  Alan then talked about using smaller rockets over heavy lift and was working to make the case that we have to work with what we have.  He also talked about evolving up from smaller, not starting off with the biggest.  Each of us responded to Alan.  It’s a discussion you do not want to miss.

William (Bill) Mellberg, Tuesday, 1-31-12


Guest:  William (Bill) Mellberg.  Topics:  Comparing aviation to commercial space regarding markets, safety, and more. Explorer 1 54th anniversary.  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 welcomed Bill Mellberg to the program to compare the early days of aviation with today’s commercial space industry. We also honored the 54th anniversary of Explorer 1.  Mr. Mellberg started the discussion with Explorer 1 by talking about the early history of Vanguard, Explorer 1, Werner Von Braun, Ernst Stuhlinger & more. Richard Easton called & we talked about timing, GPS, clock synchronization, his Dad’s work, and Vanguard early history.  Turning to our main topic, comparing the early days of aviation history to the commercial space industry today, our guest said it was a flawed comparison.  During the first segment, he explains in detail his reasoning which has to do with commercial markets, what the government is paying for regarding commercial space as compared to what it paid for with aviation, specifically the Kelly Air Mail Act of 1925.  We also talked about the early history of Fokker Aircraft Company which he tied into our discussion on markets, market timing, and production capabilities.  Mr. Mellberg addressed human spaceflight safety from the point of view that it would be extremely hard for the commercial companies to master safety given the complexities & costs of human spaceflight & the potential damage or even ruination of the company should there be a fatal accident.  Before the segment ended, our guest drove home the lack of commercial markets for human spaceflight.  There must be HSF markets other than the government market for the ISS.  

In our second segment, our guest cited some airplane examples that were ahead of the market and suffered from bad market timing.  He then used the SST as an example of the points he was making about high operating costs, no or limited markets, government subsidies, etc.  He went over the economics of why the Boeing SST was killed by our congress and what happens when the ticket price is so high that a broad market cannot be realized.  Listeners and callers asked about government regulation crippling innovation.  Bill then suggested the path to commercialization was with a program such a what Dr. Spudis and Dr. Lavoie have proposed in their paper “Using the resources of the Moon to create a permanent, cislunar space faring system” as well as on The Space Show. You can read their paper at www.spudislunarresources.com/Bibliography/p/102.pdf.  Bill said that eventually as cislunar economic develop evolves, so would commercial markets and opportunities.  He also recommended the NASA reorganization plan proposed last year by Dr. Harrison Schmitt. You can read his plan at www.spaceref.com/news/viewsr.html?pid=37176.  Our guest suggested that we should use the money being invested in commercial human spaceflight to do space exploration projects because commercial space today is an unnecessary diversion of scarce resources in a tight economy.  Throughout our discussion, he talked about government contracting and why it is different today, not commercial, and unlike what was done in early aviation and with airmail.  At the end of the program, our guest treated us to some of his political humor and impersonations per his program, “An Evening With The Presidents.”
