Update: Atlantis launched into orbit today, as I was somewhere on I70 heading home.
Space Shuttle Atlantis is due to launch into space at 2:45 in the afternoon Eastern time. However, the weather is iffy, with a front coming through (which will make my own plane ride home from Florida a bit bumpy, I imagine). Also, the launch window is a very narrow ten minutes, so the odds of the launch are pretty low.
Normally I would live-Twitter the launch, but I might not be home yet from the airport (especially if US Airways, once again, gives me a metaphorical colonoscopy as they did on the way here). If the launch is delayed, I’ll do my best to cover it live when it does eventually liftoff.
