Smithsonian Air and Space:

After flying 148 million miles and orbiting Earth 5,830 times, Discovery, first flown in August 1984, was being decommissioned and readied for its trip to the National Air and Space Museum’s Steven F. Udvar-Hazy Center in northern Virginia, where it will arrive in mid-April.The three main engines had been removed from the shuttle’s aft end, which was now covered by a tightly fitted mask with three white discs the size of the engine bells. Clear plastic stretched across the crater in the orbiter’s nose, where the forward reaction control system—small thrusters that maneuvered the spacecraft in orbit—had been removed.And this harvesting of the orbiter’s components was only the beginning.

I always wish I had seen one of these launches in person.
