    Lift-off is scheduled for 2006 Sep 06 at 16:28:51 UTC. Spaceflight Now reports
    that the weather forecast is a 70 percent probability of GO for launch:

    NASA's estimated elements are available at the following URL. They take into
    account all planned manoeuvres, and are revised  throughout the mission, as
    required.

    For quick reference, I have extracted the elsets from MECO through docking.
    
    1. Sep 06, 16:40:05 UTC (MECO) - Sep 06, 17:07:58 UTC
    
    1 99999U           6249.69450450  .01000000  00000-0  44129-6 0    09
    2 99999  51.6319 128.0941 0132743 348.7559  72.2002 16.48582173    06
    
    NOTE: NASA's MECO 2-line elset is erroneous; so I generated the above by
    converting NASA's True of Day Rotating (TDR) [aka Earth-Fixed Greenwich (EFG)]
    Cartesian state vector to SGP4, using Ken Ernandes' VEC2TLE program, and added
    realistic decay terms for the brief duration of existence of the orbit. Our web
    site has a link to Ken's program:
