The military's small, top-secret version of the space shuttle rocketed into orbit Tuesday for a repeat mystery mission, two years after making the first flight of its kind. The Air Force launched the unmanned spacecraft Tuesday hidden on top of an Atlas V rocket. As if on cue, clouds quickly swallowed up the rocket as it disappeared out over the ocean.

It was supposed to be a slow but smooth journey to retirement, a parade through city streets for a shuttle that logged millions of miles in space. But Endeavour's final mission turned out to be a logistical headache that delayed its arrival to its museum resting place by about 17 hours. After a 12-mile weave past trees and utility poles that included thousands of adoring onlookers, flashing cameras and even the filming of a TV commercial, Endeavour arrived at the California Science Center Sunday to a greeting party of city leaders and other dignitaries that had expected it many hours earlier.

At its prime, the space shuttle Endeavour circled the globe at 17,500 mph, faster than a speeding bullet. In retirement, it's crawling along the streets of Los Angeles at a sluggish 2 mph, a pace that rush-hour commuters can sympathize with.
