    That time is about 5 min too early. My guess is that you used NASA's  NC-1
    orbit, per my post, but that orbit is good only until 12:08 UTC on Thursday:

    The shuttle will be in the above orbit when it passes over North American passes
    Thursday. By the next night, it should have docked will ISS.
