Discovery Over America

Space shuttle Discovery is scheduled to land today and will be flying directly across the center of the country on its way to the Kennedy Space Center in Florida. If the shuttle makes its first possible window, the route will be as follows:

On orbit 238, Discovery will cross the western coast of North America at 12:39 p.m. EST (9:39 a.m. PST), just north of Vancouver, British Columbia. 

Traveling on a southeast trajectory, the orbiter will be passing over northwestern Montana just a minute later (10:40 a.m. MST).  Four minutes later (11:44 a.m. CST), Discovery will be streaking over southern Nebraska.  After another two minutes have elapsed, it will be racing over Springfield, Missouri, and by 11:49 a.m. CST it will be over central Alabama.  At 12:55:16 p.m. EST, the shuttle will decelerate to two and a half times the speed of sound (mach 2.5), dropping to an altitude of 80,000-feet just to the northwest of Cape Canaveral.  Touchdown is scheduled for 1:01:50 p.m. EST.  

NASA has a tracking map up at their Shuttle Page:

The shuttle should be visible to the naked eye, appearing to be about as bright as Venus - but moving very fast. Even if you don't see it, you may well here the sonic booms if you are anywhere close to the flight path.
