Well... It's Not Like They Have Much Use For Them Anymore...

Northrop Grumman Corporation and NASA have donated a set of flight-worthy solid rocket boosters from the Space Shuttle Program to the California Science Center, located in Los Angeles, California, to display with the Space Shuttle orbiter Endeavour and a real Space Shuttle external tank in a launch configuration. The California Science Center’s goal for this exhibit is to preserve and display the only existing full stack of an orbiter, genuine solid rocket boosters, and external tank in the launch position. The Space Shuttle Endeavour will be the centerpiece in the future Samuel Oschin Air and Space Center, the Phase III expansion project of the Science Center.
