The space shuttle Endeavour arrives at the hangar at the California Science Center for its last stop on Sunday, Oct. 14, 2012, in Los Angeles. Endeavour arrived at the museum after a 12-mile parade with thousands of onlookers, ending with a greeting party of city leaders and other dignitaries.

The iconic black and white orbiter, which flew 25 times to space over the past two decades, arrived at the California Science Center on Oct. 14 to begin its new mission as a museum exhibit. Endeavour had been scheduled to pull up at the CSC on Oct. 13, but natural and utility obstacles, as well as the need for maintenance of its transporters, slowed the pace of the shuttle's parade and delayed its arrival by a day.

The space shuttle Endeavour make its way down Manchester Blvd. in Los Angeles on Oct. 12, 2012. Movers had planned a slow trip, saying the shuttle that once orbited at more than 17,000 mph would move at just 2 mph in its final voyage through Inglewood and southern Los Angeles. But that estimate turned out to be generous, with Endeavour often creeping along at a barely detectable pace when it wasn't at a dead stop due to difficult-to-maneuver obstacles like tree branches and light posts
