Beginning Friday, the shuttle heads off on its last mission — a 12-mile creep through city streets. It will move past an eclectic mix of strip malls, mom-and-pop shops, tidy lawns and faded apartment buildings. Its final destination: California Science Center in South Los Angeles where it will be put on display. (AP Photo/Mark J. Terrill)
