Orion Stage Adapter Aces Structural Loads Testing: A test article of the stage adapter that will connect the Orion spacecraft to a United Launch Alliance (ULA) Delta IV rocket for its first mission, Exploration Flight Test-1, aced structural loads testing Jan. 30. Now, the stage adapter that will fly on the Delta IV is officially ready for the journey to its final exam -- a flight more than 15 times farther into deep space than the International Space Station.

For the structural loads test, the hardware was attached with lines running in different directions on the hardware. Hydraulic pressure was added to those lines in increments, which pushed on the adapter to evaluate its integrity. The test was similar to the recent "can-crush" tests on a rocket fuel tank, but the adapter wasn't purposefully buckled for the structural test as it was on the fuel tank. Twenty-five test cases were completed on the adapter.
