TIMED's Acoustic and Shock Tests

January 30, 2013
Acoustic and shock tests simulate a spacecraft's environment while riding in a rocket during launch. Acoustic tests simulate the noise and sound pressure levels inside the rocket's fairing, or the portion of the rocket in which the satellite sits during launch. Shock tests simulate the vibration a satellite experiences as it separates from the launch vehicle and when its solar arrays are deployed and its instrument covers are released. The TIMED spacecraft's acoustic and shock tests were conducted at NASA Goddard Space Flight Center in Greenbelt, Md., in November 1999.
