NASA Begins Acoustic Tests On The Space Launch System

NASA's Space Launch System will have some pretty strong engines. As a result, the engines produce enormously loud sounds. The SLS is slated to be the most powerful rocket in history. The heavy-lift launch vehicle is set to carry the Orion capsule beyond low-Earth orbit and into deeper space exploration. This month at the Marshall Space Flight Center in Alabama, engineers have begun testing a 5 percent scale model of the rocket on a similarly scaled launcher to understand more about how high and low frequencies affect it—and the crew. Engineers have created a sound suppression system for…
