SLS Payload Adapter Moved for Testing at NASA Marshall

These photos and videos show how crews at NASA’s Marshall Space Flight Center in Huntsville, Alabama, moved and installed the payload adapter that will be used in the Block 1B configuration of the SLS (Space Launch System) rocket from Building 4708, where it was manufactured, into Structural Test Stand 4697 at NASA’s Marshall Space Flight Center on March 13. Teams at Marshall will begin structural testing the engineering development unit of the payload adapter – an exact replica of the flight version of the hardware – this spring. The cone-shaped payload adapter is about 8.5 feet tall and features two metal rings and eight composite panels. The adapter, which will debut on NASA’s Artemis IV mission, is an evolution from the Orion stage adapter used in the Block 1 configuration of the first three Artemis missions. It will be housed inside the universal stage adapter atop the rocket’s more powerful in-space stage, called the exploration upper stage. The payload adapter, like the launch vehicle stage adapter and the Orion stage adapter, is fully manufactured and tested at Marshall, which manages the SLS Program.
