GPM's two solar array wings completed vibration and acoustic testing at Goddard Space Flight Center, Greenbelt, Md. The solar arrays were integrated to an identical copy of the Lower Bus Structure of the satellite for this testing. These tests and deployments demonstrate the ability of the solar array to withstand the vibrations and sounds the satellite will be subject to during launch as well as test the ability of the solar arrays to unfold once in orbit.
