    Epoch Date Age Analysis is compiled twice weekly by Satellite Tracking
    Houston- http://sattrackhouston.com The next compilation of these data
    will be Friday, 30-August-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 there are less than 36 in a
    catagory.
