Starting next month, NASA will begin delivering its four Space Shuttle orbiters to their final destinations. After an extensive decommissioning process, the fleet -- which includes three former working spacecraft and one test orbiter -- is nearly ready for public display. On April 17, the shuttle Discovery will be attached to a modified 747 Jumbo Jet for transport to the Smithsonian's National Air and Space Museum in Virginia. Endeavour will go to Los Angeles in mid-September, and in early 2013, Atlantis will take its place on permanent display at Florida's Kennedy Space Center. Test orbiter Enterprise will fly to New York City next month. Gathered here are images of NASA's final days spent processing the Space Shuttle fleet.

The flame trench at Launch Pad 39A at NASA's Kennedy Space Center endured significant flames, vibrations and other stresses during the space shuttle era. Heading into the future, designers are looking for new, flame and vibration-resistant materials to line the trench. To help in the search, a team of mechanical engineering students at Louisiana State University are to build a scaled-down version of the flame trench that Kennedy's scientists can use to try out sample materials for the trench. If the samples work in the lab, they can be tried out in the real flame trenches at Launch Pad 39A and 39B. Photo taken on October 14, 2011. (NASA/Jim Grossmann)
At Launch Pad 39A at Kennedy Space Center in Florida, the seven slidewire baskets have traveled down the wires to the ground after technicians released them from the 195-foot level for the final time, on March 16, 2012. The baskets will be removed and put in storage. The system of seven slidewire baskets at launch pads A and B provided an escape route for personnel inside the orbiter or on the orbiter access arm. The baskets are suspended from slidewires that extend from the pad's Fixed Service Structure to a landing zone 1,200 feet to the west. Each basket could hold up to three people. (NASA/Frankie Martin)
