How we stack a space shuttle
On **January 30, 2024**the California Science Center completed _Go for Stack_, the complex process of moving and lifting each of the space shuttle components into place for _Endeavour’s_ upcoming awe-inspiring 20-story vertical display. This technically challenging feat had never been done outside of a NASA facility.

The California Science Center is lifting and installing Space Shuttle Endeavour as the culmination of Go for Stack—the complex, six-month-long, multi-phase process of stacking each of the space shuttle components in vertical configuration.

Step 1
The roughly six-month long process started with the installation of the **aft skirts** which attach the entire space shuttle stack to seismic isolators beneath the new Samuel Oschin Air and Space Center building.

Step 2
On top of the aft skirts the **solid rocket motors** were stacked to form the tall, white solid rocket boosters (SRBs).

Step 3
**Forward assemblies**were placed on top of the solid rocket motors to complete the tall, white **solid rocket boosters** (SRBs).

Step 4
The orange **external tank**, _ET-94_, was lifted and attached to the SRBs.

Step 5
Finally, **space shuttle orbiter**_Endeavour_ was moved and lifted into place by a large crane, and the orbiter was mated with the rest of the space shuttle stack._Endeavour_ is in ready-to-launch configuration.
