All systems are looking good for today's Scaled Model Acoustic Test. Seen here this morning is the scaled model of the SLS on the test stand in preparation for today's testing. This test allows us to simulate the liftoff environments of SLS at a 5% scale. The data we will gain from this testing will help us design the sound suppression system. We can also use this data to help ensure the vehicle can withstand the loads at liftoff. Follow us on Twitter NASA_SLS for a rundown of the entire testing by one of our SLS engineers. #slsinspires
