Guest: Open Lines with Dr. David Livingston. Topics: asteroid mining, Planetary Resources, Inc. SLS. You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming.

We welcomed an Open Lines discussion inviting calls and emails on all space related topics. As it turned out, two topics were primary during the program and as a result of that, I will not summarize this program by segment as I usually do. First, the asteroid mining venture as put forth in the press conference for Planetary Resources, Inc. was primary throughout the program. The second commanding topic was the SLS and Op-Ed in the Houston Chronicle on April 20, 2012 by the JSC former director, Chris Kraft & Tom Moser. You can read the article at www.chron.com/opinion/outlook/article/Space-Launch-System-is-a-threat-to-JSC-Texas-jobs-3498836.php. You can read more about this Op-Ed on Space News at www.spacenews.com/commentaries/120423-fromwires-sls-threat-jsc-jobs.html. Many of the callers throughout the discussion commented on the Op Ed, the SLS, and its future. We also talked about the need for heavy lift, having a specific mission or missions for a rocket, destinations, and a time line for milestone accomplishment. Our first caller was Charles in Las Vegas who commented that he thought Planetary Resources was more “sizzle than steak.” Charles was not supportive of a business model relying on secondary payloads. Instead, he said the company had to control its own launch needs. During our three segments, many listeners said they did not agree with Charles, including me. Many of us thought it was possible to use secondary payloads and during our 105 minute program, we covered this subject with the benefits and risks of relying on others, on sole source providers, etc. As for the Op Ed, we talked about it at length, wondered about the NASA lunar study mentioned by Mr. Kraft as well as the existing rockets that could do HSF to the Moon or beyond LEO. The consensus for those calling tonight’s show was that SLS in its present format using the current management program will probably be cancelled in 2013 or 2014 despite the support Congress appears to be giving it at this time. Mixed in with the SLS calls, we did talk about the new launch date for the Falcon 9, there was lots of interest in asteroid mining and new technology development to make it happen, plus a few other topics that brought to the listeners attention. When we came back from the final break which was at the 90 minute point, I used the remaining time to highlight some of the special upcoming Space Show programs for the rest of this month into early summer.
Please post your comments/questions on The Space Show blog. If you want to email any of the callers or those sending in email questions for this program, send your note to me and I will forward it to you.

Dr. Harley Thronson, Friday, 1-27-12
Guest: Dr. Harley Thronson. Topics: “Accelerating the Future: The Importance of Human Achievements Beyond LEO Within a Decade.” You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://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 Dr. Harley Thronson back to the show to discuss the existing and future planning for human spaceflight beyond LEO (BEO). We talked about two recent Space Review articles Dr. Thronson wrote which I believe you will find very interesting. (www.thespacereview.com/article/1985/1 and www.thespacereview.com/article/1756/1. In addition, Dr. Thronson discussed the Future In Space Telecon (FISO) series that he hosts every Wednesday afternoon at 3 PM EST. To learn more about FISO and get on their mailing list visit http://spirit.as.utexas.edu/~fiso/fisowg.html and www.futureinspaceoperations.com. In our first segment, we discussed the FISO telecons, then we switched to what’s next for human spaceflight (HSF) after LEO or BEO (beyond Earth orbit). For this discussion, we referred to the two Space Review articles referenced above. As we learned, there is considerable thought being given within NASA and among others at to what is next after the ISS and how do we start preparing for it. Dr. Thronson talked about prioritizing what has to be done to move beyond the ISS and LEO. Also in the mix were mission and even hardware design compromises that may enhance our ability to be ready to fly sooner, not later. Those involved in this planning are of the opinion that we must compromise and also must fly soon, start something, otherwise we will lose opportunities and drive up costs even more than they will be. Much of this has to do with being able to capitalize on the existing ISS workforce and those who know how to do space stations and HSF. If we do not retain these people, then starting over again years later will be costly and will have a huge learning curve associated with it. The goal of planners and thinkers Dr. Thronson is working with is to be BEO by the end of the decade. We discussed where to go and here, our guest had much to say about Mars and the Moon, but said Earth-Moon libration points were best for starting out using a stepping stone approach. Much of the first segment went into detail about these subjects and issues.
In the second segment, we talked about crew safety, using previously built but never used ISS modules as the basis for a BEO station, and compromises that can get us going quicker, not later but not adversely impacting safety. Michael called in to talk about accidents and inevitable fatalities with HSF and the industry to properly handle them when/if they happen. Both Dr. Thronson and I had much to say about safety, accident management, and this subject. Another listener wanted to know when there would actually be work on BEO projects rather than just talking about them. Dr. Thronson had much about getting started, time lines, mission readiness and more.
