Welcome to our December 2012 Open Lines show.  As Open Lines programs go, this was a fairly quiet program.  I opened with a list of possible discussion topics and our first call dealt with one of the topics, the North Korean missile launch. Mike called in to update us on the latest with the launch and then he continued to give us updates during the program to the point of confirming orbital insertion for its satellite.  He also reported a successful 3 stage rocket launch for the N. Koreans.  We talked about the significance of the launch, how it surprised our intelligence services and more. We got an email from Darren in Canada telling us he liked the “passionate exchange between Zimmerman and me from the day before as that exchange was also one of the topics I suggested for discussion. After a short break, we took a call from John in Atlanta who picked up from the night before with our science fiction movie discussion.  We talked more about Forbidden Planet and John referenced the original War of the Worlds movie. John also talked about the UFO subject in the context of our sci-fi movie discussion, then he referenced the op-ed by Dr. Zubrin about Mars Sample Return missions and why Dr. Zubrin was not supportive of the EML2 mission.  From here, we went to the SLS subject and knowing John to be a strong supporter of the project, I asked him if he thought the project would be cancelled and when.  John suggested it might be slowed down before it was cancelled outright.  After another break, I mentioned the X-37B successful USAF launch and responded to two emails. One was about my Hotel Mars John Batchelor Show segments and the other asked me to explain how and why I connect the dots regarding our economic problems in the country to possible adverse impact on NASA and even in the private capital markets.  This opened the door for me to do a mini rant/lecture on how I see economics and why I connect these dots.  If you disagree, do post on the blog and share your information and perspective with us all.  Disagreement is always wanted and respected on The Space Show.  Next, Charles called in and talked about the doomed NASA Nanosat Challenge. He compared it to XPrize which he believes set the model and tone for such prizes. Charles next flung barbs at NASA, especially for the JWST, the ISS, & SLS.  At one point, he said NASA was “like a beached whale!”  Charles told us about Meetups in Las Vegas and on the national scene & he provided a brief update on the N-Prize contest.

http://thespaceshow.files.wordpress.com/2012/11/adamo-eml2roundtripr2.pdf.  We welcomed Dan Adamo back to the program and Dr. John Jurist as co-host for this special webinar addressing trajectory analysis for an EML2 mission and more.  On The Space Show blog, you will find Dan’s PDF document used during the webinar, a link to the movie he played in the second half of the webinar, and his Phobos-Grunt analysis paper we discussed near the end of the webinar. During the first hour of the webinar, Dan took us through the trajectory analysis to Earth-Moon L2 per his PDF document.  We talked about why EML2, libration points in general, and how such missions are planned.  If the resolution on the webinar video for the charts and tables used during this segment are difficult to read on your computer, please bring the document up on the PDF on The Space Show blog and follow along that way.  Dan took us through Table 1, HALO orbits, and the HOI as well as the Trans-Lunar Insertion points.  We talked about orbital characteristics, delta V, rocket size, and more  We also talked about the position of the Earth, launch windows, the Moon, & other factors influencing the planning of the mission.  While at times the discussion may seem a bit technical or overwhelming for those of us having never done mission planning at this level before, all of us will certainly have a better understanding of the factors considered and influencing both robotic as well as human spaceflight missions.  Near the end of the segment, we talked about the SLS and heavy lift & how payload capacity interacts with mission & trajectory analysis. 
 
     In the second hour of our webinar, Dan took us through his HD movie of the orbital trajectory talked about during the first segment, stopping it at intervals for specific explanations and questions.  The movie is in the QuickTime format but you can see it both on the webinar or by using the URL provided on the blog.  We took several listener calls & questions.  One asked Dan about the differences in planning for the robotic vs. the HSF mission using MSL & Curiosity as an example.  Dan pointed us to a YouTube video he made a few years ago with Dr. Logan using these tools for a Deimos mission (www.youtube.com/watch?v=X10GAqA4Ky4). Another listener called wanting to know the likelihood of an EML2 mission actually happening.  Dan explained why he believed this mission to be the next stepping stone in HSF.  More was discussed about SLS with Dan raising some concerns about its real capabilities & wondering if Congress is being sold unrealistic expectations. We talked about heavy lift in general & with the support of properly placed depots.  SLS and the difference with a Falcon Heavy were also discussed in terms of what the differences would mean in payload, number of launches, costs, risks, etc.

Guest:  Open Lines with Dr. David Livingston.  Topics:  Space Show surveys & feedback, SatCon 2012, post election space policy & more.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://thespaceshow.wordpress.com.

Welcome to our nearly 2.5 hour Open Lines discussion on a wide range of topics. Most of our topics covered the entire show so this summary is in just one segment. In addition to a few talking points at the beginning of the show, I stressed the need for more Space Show listener feedback and the use of possible surveys.  The survey issue came up with several callers and many ideas for surveys were put forth.  If you have ideas or suggestions for better Space Show feedback including the use of surveys, please post your ideas on The Space Show blog. In addition, we had some strange phone line issues throughout this program.  We are working to track down what happened but since there is no call waiting at our end, I’m not sure the problems were with our equipment.  Regardless, The Space Show apologizes for the phone line distractions. Daniel, a first responder, called in with a brief summary of the recently completed SatCon 2012 Conference in NYC.  He had some very interesting things to share with us, especially about national security satellite issues.  Check out this conference at www.satconexpo.com. Tim called to talk about our recent program regarding JP Aerospace.  Tim said he was working the numbers and does not feel that an airship can make it to orbit.  Let us know if you agree with Tim.  By the way, others on earlier programs have made it clear that they do not believe JP can get an airship to orbit.  In the meantime, John continues to work the problem and best of luck to him and his crew in figuring out how to reach his goal.  Doug called in and we talked post election space policy. A few other callers did the same thing including John from Atlanta.  I really had no great insights to bring to the table but I suspect that more likely based on how things go with the economy and sequestration, the status quo will prevail on space policy.  That said, the SLS program might actually be a target of NASA budget cuts over the next few years but it is way too early to tell.  Some listeners seemed to want a partisan discussion on policy and I did my best to avoid it though I did disclose my dislike for our two main political parties.  I was also clear that the private sector engaged in capital acquisition was at risk through increased regulation, taxes, inflation, etc.  Like everyone, I am hopeful that risk capital will remain strong and space ventures will be able to grow in their share of this unique investor market, but it is a fragile market given our economic situation and the uncertainties ahead of us at this time.  John from Winterhaven called about my comments regarding doing something with one’s ideas and concepts over and above just speaking the words or writing a paper. I referred to this throughout our discussion as “breathing life” into one’s concepts/ideas.  I am also planning a full Space Show on this subject.  Other topics included news stories on the Falcon engine problems and EML2 NASA missions.
