The California Science Center continued Go for Stack with the installation of ET94, which was mated to the Solid Rocket Boosters at the construction site of the future Samuel Oschin Air and Space Center.

The last remaining flightqualified External Tank in existence, ET94 is the largest component of the shuttle stack, weighing 65,000 lbs. and standing 154 feet top to bottom, with a diameter of 27.5 feet. ET94 will ultimately be a part of the world's only authentic, readytolaunch space shuttle stack in the Samuel Oschin Air and Space Center.

Go for Stack is the complex, multiphase process of moving and lifting each of the space shuttle components into place for Endeavour’s upcoming aweinspiring 20story vertical display in the Samuel Oschin Air and Space Center. This upcoming addition to the California Science Center will serve as a launchpad for creativity and innovation which will inspire future generations of scientists, engineers, and explorers.
