We welcomed Dr. Henry Hertzfeld back to the show for a fascinating 90 minute discussion regarding commercial space, human spaceflight (HSF), recently announced HSF Mars missions, increasing the launch rate, and more.  During our initial segment, Dr. Hertzfeld addressed my question about lowering launch prices to increase the launch rate.  Dr. Hertzfeld did a classic economic study on this subject several years ago and I asked him if today’s current market and commercial space progress had altered his earlier conclusions.  He said no. Later, I asked if space solar power (SSP) could drive launch rates down.  The short answer was no but don’t miss what he had to say about SSP economics, launches, and debris issues.  Jerry emailed in a question about SpaceX being a commercial company given its receipt of government money.  Henry had much to say about what makes a company commercial or not and if it is even an important issue.  Another listener wanted to know about the deep space commercial ventures announced in 2012 and in 2013.  The listener wanted to know if these were really commercial ventures, if regulations could stop them, and what would happen re the ventures needing property rights or the equivalent.  One of the things our guest reiterated several times during our discussion was the need for stability and predictability for the commercial industry.  Questions came in about benefit sharing and he mentioned the likelihood that some sort of international system would develop on these issues. I asked what constituted an acceptable ROI and the example of controlled ROIs as in the utility industry came up.  Doug wanted to know about rocket reusability and its impact on launch costs.  We also talked about both Mars One and the new Inspiration Mars mission.  As part of this discussion, astronaut rescue and the rescue treaty were discussed.  In the second segment, Doug called to discuss property rights for a NEO as opposed to the Moon, wondering if the Moon might be more valuable.  Doug & Henry talked about our having returned lunar rockets as a model for commercially returning lunar products but Henry suggested there might be a difference in returning something for science as compared to commercial exploitation.  Later, we addressed human spaceflight and its challenges.  The Chinese space program was brought up as was the risk of a space war.  Dr. Hertzfeld was asked about putting 10,000 people on Mars, space migration, species survival, space settlement, and the need to explore as possible drivers for HSF.  My final question pertained to our evolving to a business friendly environment in space.  Simply put, we are not there yet.

Guest:  Andrew Chaikin. Topics:  Neil Armstrong & his One small step for man lunar comment, space policy, space media, and more.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://thespaceshow.wordpress.com.

Contact The Space Show for further information.  We welcomed Andy Chaikin back to the program. Please visit his website for more information, www.andrewchaikin.com.  We started our discussion with Andy telling us about the BBC documentary with Neil Armstrong’s brother’s comments about Neil’s famous Apollo 11 landing statement, then the Guardian’s (a UK paper) calling Neil a liar.  Much of our first segment was devoted to this story and incident.  We then moved on and talked about Golden Spike as Andy is part of the Golden Spike team.  He had some very interesting nontechnical and general observations about the effort, the timing, and the Golden Spike team.  Also in this segment, we talked about the need for low cost space access, then listener Paul in Houston asked Andy about the impact on the new space business given the US and global economy.  This started an interesting conversation assessing where we are as a nation and culture today and the options we have for moving forward or not.  Both Andy and I talked about solutions going through space but neither of us could say which way we might end up going.  We also talked about the media and its problems, a discussions that was carried forward to the next segment.

     In the next segment, we started with a call from Doug who had additional comments on the Armstrong story.  We also talked about the need for sustainable commercial space, again focusing in on the need to lower the cost to space.  Andy then talked extensively about lessons learned at NASA over the years and the book he is writing for NASA on the subject which addresses the principles of success in spaceflight and management.  Our policy and historical overview and current assessment continued to the end of this nearly two hour program.
