    The Progress deorbit burn is not scheduled to occur until ~01:27 GMT.  Since
    there is a visible ISS pass over Moscow at about that time (0427 local),
    anyone in Moscow and maybe parts of Europe should consider going out to see
    if they can see the burn.  Progress undocked retrograde and is thus leading
    ISS.

    I had thought about that.  We know that there are some good
    mathematicians in Al-Qaida, and that missions to the ISS must launch at a
    specific time, +/- 2.5  minutes.  So, as far as I can tell, making the
    ISS secret seems to be the next logical course of action.  I don't think
    that a launch to the HST is supposed to occur for a couple of years....
    
    As for science and satellite deployment missions (where the exact launch
    time is non-critical), NASA could launch at anytime during the announced
    4-hour launch window.

    Maybe an attack on the launch pad/Space Shuttle would require more than
    24 hours of planning.  Perhaps it would be time critical.  If they got a
    hijacked plane through the security net (somehow..), they couldn't just
    hover around, waiting for the launch to occur.

    It is true, the Shuttle launches to ISS more than all other targets
    combined over the long haul.  I suspect that the ISS TLE may soon become
    classified.  I hope not.  I was reading on Space.com, I think, that
    during DoD Space Shuttle missions 1985-1990, the launch time would not be
    announced until the clock hit the T-9 min. hold.  It was a virtual media
    blackout during the mission, I read.  If media blackouts are to be
    imposed, then that would be greatly disappointing.
    
    
    I watched the Progress undock from the ISS today at 12:43 EST (17:43 UT)
    on NASA TV in darkness.  A few minutes later, it was in sunlight.  It was
    departing the station at 0.2 meters per second.  A deorbit burn was
    scheduled for something like 15:40 EST (20:40 UT).  As I write this at
    16:01 EST (21:01 UT), I assume that the Progress is just about destroyed.
     The next Progress will be launching soon, and is scheduled to dock on
    the afternoon (EST/UT) of Sunday, March 24th.
    
    
    Now, let me sign off and prepare for the flaming e-mails I am about to
    receive....
