Media Invited to Listen to the Sound of Progress as Scale SLS Acoustic Testing Continues at NASA Marshall Center
What: Local media can hear the sounds of progress on NASA's Space Launch System (SLS) when engineers perform acoustic tests on a 5-percent scale model of the new rocket May 29 at NASA's Marshall Space Flight Center in Huntsville, Alabama. This will be the first acoustic test on a fully assembled scale model of the launch vehicle, which includes solid rocket motors. Acoustic testing on the core stage began in January. The mini model will be ignited, giving important data on how low- and high-frequency sound waves affect the rocket on the launch pad. This testing will show how the powerful noise generated by the engines and boosters may affect the rocket and crew, especially during liftoff. The data will then be used to verify the design of the rocket's sound suppression system. Water is the main component of the sound suppression system because it helps protect the launch vehicle and its payload from damage caused by acoustical energy. Who: SLS Chief Engineer Garry Lyles; Acoustics Engineer Jeremy Kenny; and Ralph Carruth, manager of the Test Lab at the Marshall Center, will provide an overview of the acoustic testing and give a tour of the test stand and control rooms at the facility. When/Where: 12:30 p.m.-2 p.m. CDT, Thursday, May 29 To attend: News media interested in attending should contact Kimberly Henry in Marshall's Public & Employee Communications Office at 256-544-0034 no later than 4 p.m. CDT Wednesday, May 28. Media must report to the Redstone Arsenal Joint Visitor Control Center at Gate 9, Interstate 565 interchange at Rideout Road/Research Park Boulevard no later than noon Thursday, May 29. Vehicles are subject to a security search at the gate. News media will need two photo identifications and proof of car insurance. The first flight test of the SLS, which will feature a configuration for a 70-metric-ton (77-ton) lift capacity and carry an uncrewed Orion spacecraft beyond low-Earth orbit to test the performance of the integrated system, is scheduled for 2017. As the SLS evolves, it will provide an unprecedented lift capability of 130 metric tons (143 tons) to enable missions even farther into our solar system to places like Mars.
