    NASA has posted pre-flight estimated elements to the following site (click on
    the red icon):
    
    http://spaceflight1.nasa.gov/realdata/elements/index.html
    
    I have appended the elsets covering about the first 25 h after launch. Be
    careful to use the correct elset for the time period of interest to you.
    
    Based upon a quick look at potential visibility, I offer the following general
    comments:
    
    Southern hemisphere observers appear to have marginal morning viability of the
    orbit in the early part of the mission, but will have evening visibility later
    in the mission. 
    
    Most northern hemisphere observers will not have a visibility window during the
    mission. Those not too far north of the equator will have morning visibility
    late in the mission.

    1. MECO: use from July 26 at 14:49 UTC until 15:17 UTC
     
    MECO                                                      55 X 230 km
    1 99114U          05207.61769676  .01000000  00000-0  37651-6 0    08
    2 99114  51.6451  59.3990 0133625 347.8469  69.9858 16.48995563    05
    
    NOTE: NASA's MECO 2-line elset has a mean motion of 18.43 rev/d, which 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. Our web site has a link to Ken's program:
