Reminder: Discovery go for launch at 06:21 EDT

The Space Shuttle Discovery is ready to blast into space at 06:21 Eastern time (10:21 UT) Monday morning. The ground track for this launch will make it visible well up the East Coast of the US, so if you're awake at that time, you may see Discovery to your southeast as a bright light moving rapidly across the sky. You can follow the launch on the NASA Launch Blog, or watch it live on NASA TV.
