NASA Turning Down Rocket Volume

A 5-percent scale model, including solid rocket motors, of NASA's Space Launch System (SLS) is ignited to test how low- and high-frequency sound waves will affect the rocket on the launch pad. The data collected from the tests will be used to help direct and verify the design of the rocket's sound suppression system. SLS will be the most powerful rocket in history for deep space missions, including to an asteroid and ultimately to Mars. (NASA/MSFC/David Olive)
