Service module testing in Plum Brook

The European Service Module structural test model, shown on Jan. 23, 2016, is used for testing purposes before installing the real thing. It is as close to the flight version as possible while keeping costs and development time manageable. The structure and weight are the same, while mass equivalents stand in for electronics boxes not needed for the series of tests...The model was installed under a test version of the Crew Module Adapter, and sits on the Spacecraft Adapter that will attach Orion to its launch vehicle. This is the first time the European hardware has been physically connected to NASA’s elements...The service module will be shaken at NASA’s Plum Brook station in Sandusky, Ohio, USA, to recreate the vibrations of launch, as well as being subjected to acoustic and shock environments.
