    Epoch Date Age Analysis is compiled twice weekly by Satellite
    Tracking Houston- http://sattrackhouston.com The next compilation
    of these data will be Friday, 11-Oct-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.
