We welcomed Brian Weeden back to the program to discuss the issue of the shutting down of the USAF Space Fence. Our discussion was based on Brian’s August 26, 2013 Space Review article, “Gambling with a Space Fence: An analysis of the decision to shut down the Air Force Space Surveillance Fence” at www.thespacereview.com/article/2357/1. During the first segment of our 1 hour 29 minute discussion, Brian provided us with a brief history of the Space Fence, what it has been used for, its technical characteristics, and it recent cancellation partially due to sequestration regarding its approximate $15 million annual budget expense. Brian also explained its capabilities in detecting spy satellites, space debris and other objects and the size of objects which it can detect. He discussed both continuous wave radar and pulsed radar, pointing out that the fence which dated from the late 1950’s, was uncued. Richard Easton called in as his father Roger was one of the developers for the space fence in January 1958. Richard contributed greatly to our discussion. Brian then talked about the probable replacement for the fence, an S Band fence which would result in higher frequencies enabling the detection of smaller objects, probably with a very high rate pulsed radar. Right now the S Band fence is estimated to cost about $1.8 billion but as you will hear, it may never be built. As to how our national security has been impacted without the fence operating, Brian said it was difficult to assess so listen carefully to his analysis. Brian also talked about challenging DOD budget issues, the difference in budget years with DOD as compared to the government as a whole, and again, sequestration.
In our second segment, Brian addressed several of the political issues surrounding the space fence issue. When asked how long it would take for the S Band system to become operational were it funded, he said around 2018. Two companies are competing to do it if and when the project is authorized and funded. We also talked about the U.S. sharing satellite tracking information with all satellite operators including private companies, thus using an international partnership to finance the space fence since it benefits everyone. As you will hear, there appears to be control and sensitivity issues which prevent the air force from going that route. Later I asked Brian about stealth satellites and then he took a listener question about the way space debris was portrayed in the movie Gravity. We spent some time discussing the impact of a movie like Gravity on the public regarding the space debris issue. As the program was ending, Brian said he was not that optimistic about a replacement fence and brought to our attention the need to upgrade computer systems that process the data. As you will hear, this is a substantial problem that is not being addressed.

We welcomed our three panel members, Dr. Ray Williamson, Dr. Tim Spahr, and Dr. Mark Boslough to this 1 hour 31 minute Secure World Foundation sponsored webinar addressing NEO impacts and what’s being done to deal with the threat. During our fist segment, we introduced our panel members and each provided us with opening comments about planetary defense and the risk and issues concerned with Near Earth Object (NEO) impacts here on Earth. Among the many issues discussed were funding priorities, diversion of funds, the recent Chelyabinsk NEO impact in Russia, and they type of damage that can be done by a NEO impact, even a small one. We also talked about our present day capabilities, what we can detect and the NASA NEO survey. One of the listener questions led to a discussion on the risk rewards for prioritizing not only budgetary expenses for NEO searches and mitigation, but also the theory behind the strategy of identifying larger NEOs first and why that is the preferred methodology. Our guests mentioned about 400,000 items had been surveyed and cataloged so far. Marshall emailed in a question about the best location for placing telescopes for NEO searches. I also asked about NEO airburst and if they were as predictable as understanding nuclear weapon airburst. The answer was no because we know so very little about NEO airbursts in contrast to what we know about nuclear weapons. The segment ended with a short summary of what was happening policy wise in the field with SWF & other international space & policy agencies.
In the second segment, we started off talking about mitigation strategies and potential tools/methods that might be used. We talked about the time line needed to mitigate a potential NEO impact and learned that if it was within a few years of possible impact, the strategies would likely focus on damage control, evacuation, and such here on Earth. We discussed more about NEO budgets and priorities, then I asked each of our guests to rate their level of satisfaction with the progress being made in the field. Each one provided his own satisfaction rating with his reasons for the rating. I’m sure you will find their comments most interesting. Near the end of our webinar, our panel members were asked for their thoughts on human spaceflight and the possible competition for scarce funds with the planetary science part of NASA and space as well as the planetary defense budget. While they all liked human spaceflight, you might be surprised by the answers each of our panel members provided us. Guest closing comments were excellent so don’t miss them.

Space Show-SWF Webinar, On-Orbit Satellite Servicing, Sunday, 8-19-12
https://vimeo.com/channels/thespaceshow – Webinar Video
Guests: Brian Weeden, Richard DalBello, Major General, USAF (Retired) James B. Armor, Jr.. This is a SWF sponsored webinar addressing issues related to the on-orbit servicing of satellites. You are invited to comment, ask questions, & discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, & any discussion must be relevant & 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. PLEASE NOTE THAT THIS IS A TWO HOUR WEBINAR PRODUCTION SPONSORED BY THE SECURE WORLD FOUNDATION (SWF). YOU CAN VIEW THIS WEBINAR AT https://vimeo.com/channels/thespaceshow. We welcomed Brian Weeden, Richard DalBello, & Major General, USAF (Retired) James B. Armor, Jr. to the program for an in-depth discussion of on-orbit satellite servicing. This is a new business/industry that is emerging with great interest from governments, the satellite industry, & many other interested parties. During our first webinar hour, our guests explained satellite on-orbit servicing, why the interest in it, the values on the table, & the economics behind this developing industry. We heard from the perspective of the satellite operator with Mr. DalBello, from General Armor with the perspective of a company wanting to provide these services plus what they are commercially doing now in this emerging industry. Gen. Armor talked about the new ATK venture for satellite repair, Vivisat (www.vivisat.com). He was followed by Mr. Weeden who connected the dots with us regarding the big picture implications for security, stability, & policy. We talked about liability issues, insurance, & LEO & GEO satellites in terms of their respective economic value & lifespan. A listener asked about GPS satellites, launch costs, & competition here & abroad. In fact, Brian mentioned several projects outside the US with the Canadians, Germans, & JAXA. Toward the end of the first hour, caller Jack asked about testing & reliability, wondering if repairing satellites would reduce reliability engineering & testing on the ground, thus lowering the satellite’s cost given the possibility of on-orbit repair. Ben followed asking if satellites having a longer life would be sold, comparing this potential to selling real estate once a property has been fully depreciated.
In our webinar second hour, Brian described the DARPA Phoenix Satellite Service project, http://www.darpa.mil/our_work/tto/programs/phoenix.aspx. The issue of satellite abandonment came up & as you will hear, there is no way to abandon any object in space. Another issue in this segment was space situational awareness (SSA). We talked about SSA in LEO, with the new entrepreneurial small satellite companies doing LEO ventures, & the implication of this new industry for launching to & operating in GEO. Later in this segment, we learned that there was no commercial incentive to address the space debris issue. Don’t miss the analysis behind this statement as its important in understanding the space debris issue. A listener asked Richard about launch vehicle insurance & premiums, specifically for the Falcon 9. Also in this segment we talked about the NASA satellite servicing mission, the Restore Mission (http://ssco.gsfc.nasa.gov/robotic_servicing_mission.html). As our webinar drew to a close, we addressed the importance of a STEM education for our young students & the exciting space projects that today’s students will get to do in their careers. Everyone’s closing comments reflected the future orientation & focus for this evolving industry.
Please post your comments/questions on the blog. If you want to email our guests, send your note to me & I will forward it for you.

Guest: Dr. Dwayne Day. Topics: The future of the U.S. astronaut corps & the Chinese space program & intentions. You are invited to comment, ask questions, & discuss the Space Show program/guest(s) on the Space Show blog, http://thespaceshow.wordpress.com. Comments, questions, & any discussion must be relevant & 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. The Space Show/OGLF is now engaged in its annual fundraising drive. Please see & act upon our appeal at http://thespaceshow.wordpress.com/2011/11/21/space-show-2011-fundraising-campaign. We welcomed Dr. Day back to the show to discuss the NRC/National Academies report he directed, “Preparing for the High Frontier: The Role & Training of NASA Astronauts in the Post-Space Shuttle Era.” You can download this report in .pdf format for free: http://www.nap.edu/catalog.php?record_id=13227. Later in the program, Dr. Day talked about the Chinese space program based on his Space Review article from Nov. 14, 2011, “Staring into the eyes of the Dragon ( www.thespacereview.com/article/1970/1)”. We started our discussion talking about the astronaut corps of the future. Dr. Day told us about the study panel members, their methodology, their visit to JSC in Houston to see the training facilities, & their discussions with many of the commercial companies working on CCDEV. Their initial assumptions that were proven wrong were that NASA had too many astronauts & the use of the T-38 were not that vital to the program. They discovered that the astronaut corps had already been downsized. Dwayne provided us with a chart which is on the blog for this program showing the astronaut corps population going back to 1959 projected to 2016. The panel looked at three issues at the start of their task: The future role of the corps & its size; Training facilities & needs post shuttle; Training aircraft such as the T-38 for spaceflight readiness issues. During this segment, Dr. Day discussed their work & conclusions in detail. Several questions were about comparing the U.S. astronaut program with the Russians & the training involved with astronauts from other countries. Many listeners wanted to know about the role of commercial launch providers & even if there might be a private astronaut corps. One of the things Dr. Day said was that two commercial astronaut models were being examined by NASA, the rental car model & the “we are in charge” model. He also talked about the impact on the program, planning, & development of uncertainty. As for the T-38s, the conclusion was that they were needed for real time space situational awareness training & decision making. In our second segment, Dwayne took a few New Space focused questions. He mentioned talking to Space X & other companies plus what his panel heard as to their suggestions for the astronaut corps. Later, we talked about NRC reports in general, avoiding conflict of interest, & taxpayer value. A listener from Canada asked about the possibility of a private astronaut corp returning to the Moon before government astronauts. This led to a discussion about space enthusiasts & reality checks. For the balance, we talked about the Chinese program. Here, Dr. Day broke it down between human spaceflight & their defense, science & image satellite programs. He also talked about Chinese intentions. I urge you to read his excellent Space Review article referenced above. For 2012, I will do my best to offer Space Show listeners programming on the Chinese program, including webinar panel discussions, as it is important for us to understand as much as possible about the Chinese program. Post comments & questions on the blog URL above. You can email Dr. Day at firstname.lastname@example.org. If you do email him, please copy me so I can learn from the exchange.
