Spot the shuttle!

Tuesday marks a big day for space shuttle Discovery: The shuttle will take the last flight of its career. Discovery is headed from Kennedy Space Center in Florida to the Smithsonian National Air and Space Museum, just outside Washington, where it will transition from explorer to educator.

To celebrate the shuttle's final flight, we're partnering with NASA and the Smithsonian to track Discovery's journey from Florida to Washington. That's where you come in: If you're in the southeastern U.S., we want you to join other space enthusiasts to try to spot the shuttle during its trip tomorrow and share your photos on CNN iReport!
