The space shuttle Endeavour is on its last mission today, a 12-mile creep through Los Angeles city streets on a 160-wheeled carrier. It is passing through neighborhoods and strip malls, headed toward its final destination, the California Science Center in South Los Angeles. At times, the shuttle has barely cleared trees, houses and and street signs along a course heavily prepared for the trip. The move will cost an estimated $10 million, according to the Exposition Park museum. Gathered here are a few images of Endeavour's last journey.
