Welcome to our Open Lines discussion.  In the first segment of this 2 hour 2 minute program, I put forth some suggested topics and once again, I explained phone line issues for listeners regarding land lines, VoIP, compression, cordless phones, cell phones, digital phones, and even fiber lines.  Phone line issues remain the number one problem faced by The Space Show in delivering quality audio so once again I went over the requirements and the restraints based on our equipment and broadcasting equipment in general.  Several listeners did comment on the phone line issues via email.  John from Florida was the first caller and he talked about Ernst Stuhlinger and his work plus he requested Dr. Jeff Hoffman of MIT return as a guest to the show.  During our conversation, I mentioned ULA CEO Tory Bruno recent & his lecture at Stanford on the pros and cons of rocket reusability (www.youtube.com/watch?v=9DMb2yHh5CA).  Marshall was the next caller who talked about cell phones and the DSP computer in the phone. He also talked about SOHO and replacing old satellites with new ones. We talked about the cost of doing that and Marshall said he would gladly pay 5% more in taxes if he was guaranteed the money would be used for satellite replacement. I asked other callers if they would do that but nobody bothered to respond.  Marshall said we needed a satellite replacement program so jokingly, I suggested a Cash For Old Clunker Satellites modeled after the Cash for Clunkers car program several years ago.  Michael Listner called to talk about recent news articles suggesting the FAA was going to regulate lunar business.  He clarified this for us.  Emmet sent us a note suggesting Doug had a video on the net which had gone viral thus making Doug an internet star (www.youtube.com/watch?v=Rzy63276GEg).

In the second segment, Doug called the show & explained the video as a product of http://www.moonandback.com.  Doug talked about the planned SpaceX launch later in the day, the recovery of the first stage and the Falcon Heavy as part of his overall heavy lift discussion.  He also raised some questions about the Dawn Mission and its potential findings regarding Ceres.  Turbo pumps came up as did other issues with liquid rocket motors such as which fuel to use given my promoting the late April webinar addressing these and other rocket issues.  Ken from Dallas called to talk about Moon Day set for July 18, STEM, and he also mentioned Asteroid Day set for June 30.  As Ken is a sci fi movie authority, we talked some movies and TV shows.  John from Ft. Worth called and mentioned a movie and the satellite being launched by SpaceX nicknamed the Al Gore Satellite for Climate Change.  John briefly mentioned The Telegraph article showing how temperature data had been tampered with and calling it the biggest scandal ever (www.telegraph.co.uk/news/earth/environment/globalwarming/11395516/The-fiddling-with-temperature-data-is-the-biggest-science-scandal-ever.html).  John put forth some growth and population statistics as part of his argument against global warming.  Other subjects mentioned during this open lines by listener emails included why there was no live streaming of the first stage recovery attempt for the Falcon 9, why drones were not suitable for live streaming as they were with the Orion flight, plus many listeners emailed in about Cash for Clunkers & old satellites and the projects and work of Ernst Stuhlinger.

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.”
