    *********************************************************************
    
    Epoch Date Age Analysis is compiled twice weekly by Satellite Tracking
    Houston- http://sattrackhouston.com The next compilation of these data
    will be  Friday, 20-Sept-2002, at noon CDT (17:00 UTC). The epoch date
    is the time at which the orbital data  (Keplerian elements)  have been
    calculated.  Satellite names are listed when less than thirty-six (36)
    in a category.
