Testing 1-2-3! Engineers at the NASA’s Plum Brook Station in Sandusky, Ohio, began the first of a series of modal tests on an #Orion service module structural test article provided by the European Space Agency. This test vibrates spacecraft structural elements at various frequencies to simulate how launch vibrations and acoustics will affect the vehicle. More progress toward human exploration missions in deep space!
