Join me at NASA-TV for the launch.
The crew is strapped in and going thru checklists. The hatch is still open, but will be closed soon. Lift-off is scheduled for 10:39 EST, but NASA-TV gives you a great run-up to the main event, with explanations of main steps along the count-down path and some beautiful video of the launch.
I encourage you to get your link to the TV site going early, because when it gets close to liftoff, you may experience difficulties initiating a new link-up.
The weather looks good!
