At Ball, engineers use vibration pads to see how satellites shake, but the true test of a spacecraft's mettle comes from concert speakers.
The speakers shown here hit 800,000 watts, and come from the same company that provides the audio for the Rolling Stones.
A space-bound instrument or a satellite skeleton will sit in this wall of sound while engineers blast white noise at it, at roughly 145 decibels. That's a little louder than the sound of a jet engine, and simulates the sound of launch. "You can't be in the room when it's on, even with hearing protection," Hutchison said. In this image, a component of the JWST is ready for its Memorex moment.
