There are no laws violated by this so there should be no concerns that we are tracking a non-operational, dead satellite. No different than any other hunk of junk decaying from orbit. While I am sure that the folks in the NRO aren't happy, there is absolutely nothing that is inappropriate about tracking or monitoring via radio any space object whose information has been derived from public sources (monitoring or visual observation). That is what we can do in a free society. And if the NRO doesn't like it, tough stuff. If the want that kind of secrecy, they can hot the road and go to a dictatorship. ;-)) Larry Van Horn, N5FPW Monitoring Times Assistant/Technical Editor Milcom Monitoring Post: http://mt-milcom.blogspot.com/ Btown Monitoring Post: http://monitor-post.blogspot.com/ ----- Original Message ----- From: "Ciprian Sufitchi" <ciprian@sufitchi.com> To: <seesat-l@satobs.org> Sent: Friday, February 01, 2008 11:42 AM Subject: RE: Updated elements of USA 193 and Heavens-Above pass predictions > Hi all, > > Apparently space-track.org does not distribute any keplerian data for > satellite 29651 (USA 193).
