Return to Flight - NASA prepares for Discovery launch today

It is looking good for the anticipated 3:51pm launch of Space Shuttle Discovery, despite problems with a window cover that fell off the orbiter yesterday and a problem with a launch pad heater during fueling this morning. The orbiter is fueled up as of 9am, and the short delay won't affect the launch (NASA builds extra time into launch preparation for problems like these).
