This site helps you plug in your zip code so you can see if there is a fly by of the ISS or Shuttle tonight. The passes on Sunday night and last night were so big and bright in the DFW area. Tonight, we get a double one because the shuttle undocked today. Look West at 935pm and watch the bright star (that does not wink) cross overhead. No clouds, so far, so it oughta be a good one.
