We welcomed Michael Listner back to the program to discuss space debris and Apollo artifact issues along with his ideas for possible solutions to the debris problem. On The Space Show blog, you will find three of Michael's Space Review articles on the subject plus his Power Point slide presentation at the end of the blog summary statement. In addition, Michael had an article in the current Space Review on the preservation of Apollo historic sites. For this article, see www.thespacereview.com/article/2290/1. In the first segment of our 1 hour 44 minute show, Michael offered us his definition of space debris and pointed us to his slides which I urge you to have available when listening to this show. Again, his slide presentation is uploaded to the blog for this program and is the last item of the uploads. He summarized the space debris issue as both legal and thorny! After defining debris and the issues using the first few of his slides, he talked about other issues including ITAR, property rights, technical, and even national security issues. Listeners asked him several questions, mostly focused on LEO as that is the most crowded region at this time and the priority for debris mitigation. CubeSat issues came up given the potential debris problem should the cubesats manifest in the quantity talked about and planned. We talked policy issues and different strategies as suggested by China and Russia. We also talked about weapons issues and dual use for the military as well as for civilian use. Michael went over Transparency Confidence Measures (TCMs) instead of new treaties and mentioned the proposed Russian/Chinese treaty, PPWT, which does not have wide support in the UN. Late in the segment, Michael talked about the OST and the definition of a space object. We also talked about space salvage compared to ocean salvage. He told us to check out Project Azorian www.gwu.edu/~nsarchiv/nukevault/ebb305) (but did not tell us what this was. In our second segment, Michael wanted to focus on solutions & he offered us some of his ideas on the subject. Still referring to his PPT slides. One suggestion was to offer limited liability to third parties or those working to mitigate a debris issue, similar to what many of the commercial spaceports are doing with the suborbital spaceship companies and manufacturers. He talked quite a bit about the proposed Swiss concept for debris mitigation which he liked very much. Michael wrote another Space Review article on this concept last year which you can read at http://www.thespacereview.com/article/2032/1. Toward the end of the program, we talked about the need to preserve the Apollo landing sites as historical sites and some of the issues and challenged faced in doing so.
