    At some point, I expect official planned elements to be available via this page:
    
    http://spaceflight.nasa.gov/realdata/sightings/SSapplications/Post/JavaSSOP/orbi
    t/SHUTTLE/SVPOST.html
    
    In the meantime, appended are my estimates, assuming lift-off as scheduled, on
    2005 Jul 13, at 19:50:52 UTC.
    
    The MECO orbit is for the benefit of European observers, who will have a pass
    near their sunset, less than 20 min after launch. It is derived from the
    pre-launch elset I provided for STS 111, which proved to be very accurate, based
    on observer's reports.
    
    Care should be taken to use the elements only within the stated date/time
    limits. Use the NC-1 orbit for the shuttle's passes over North America.
    
    I obtained the time of the OMS-2 and NC-1 burns, and the post NC-1 orbital
    dimensions, from Bill Harwood's SpaceCalc flight plan, available in spreadsheet
    form on his site at CBS News:
    
    http://cbsnews.cbs.com/network/news/space/SpaceCalcPC_114.zip
    
    and in html at Spaceflight Now:

    I expect the following elements will be accurate to well within 1 minute of
    time, within the stated date/time limits. Of course, it can't hurt to allow for
    a few minutes of error.
    
    
    1. MECO: use from July 13 at 20:00 UTC until 20:29 UTC
    
    MECO                                                      54 X 236 km

    2. OMS-2: use from July 13 at 20:29 UTC until Jul 14 at 00:53 UTC
    
    OMS-2                                                    156 X 236 km

    3. NC-1: use from Jul 14 at 00:53 UTC until 12:08 UTC
    
    NC-1                                                     227 X 308 km
