Duck? Where? Where's the duck...OW!

Now that Atlantis is safely on the ground, all systems are go for the shootdown of the doomed USA-193 satellite. For a notionally “secret” satellite, it’s surprising how much we know about it.

Hawaiian readers (are there any? If there are, send me a postcard!) might be able to see the impact in the western sky around 0255 UTC on Thursday. Or, if they miss, around 0305 UTC on Friday. Or, if they miss again, around 0313 UTC on Saturday. (They’ll only have three shots, so if they miss it on Saturday, we’re all gonna die horribly. Or perhaps not.)

BREAKING: Bad weather in the North Pacific means they may not take a shot at it tonight.
