Sierra Space, a commercial space company and defense tech prime that is Building a Platform in Space to Benefit Life on Earth, announced the successful completion of acoustic testing on its Shooting Star cargo module at NASA\u2019s Kennedy Space Center, moving the spacecraft a significant step closer to launch readiness. The test, the first of its kind to be conducted inside the Space Systems Processing Facility (SSPF), replicated the intense acoustic stresses Shooting Star will need to withstand during a Vulcan Centaur rocket launch to the International Space Station (ISS).<\/p>\n
During the Direct Field Acoustic Test (DFAN), the test team placed stacks of purpose-built loudspeakers \u2013 each one a highly-engineered acoustic device \u2013 in 21-ft-tall columns surrounding the spacecraft. Their goal was to test whether the structural elements of Shooting Star could withstand the acoustic environment of a launch on a Vulcan Centaur rocket. Over a four-day period, test engineers blasted the spacecraft with a controlled sound field that was 10,000x higher intensity than the volume of a typical rock concert, recreating the sonic intensity of a launch. Shooting Star withstood acoustic levels greater than 140 dB for several minutes at a time, proving its flight worthiness.<\/p>\n
\u201cOur innovative Shooting Star cargo module offers the capability to deliver additional capacity, flexibility and power to a wide range of missions,\u201d said Sierra Space CEO, Tom Vice<\/strong>. \u201cIn our first mission, Shooting Star will carry critical science, food and cargo to the International Space Station for NASA, and our cargo modules will continue to play an integral role in bringing supplies to space as we build a Low Earth Orbit economy through commercial spaceflight.\u201d<\/p>\n Shooting Star attaches to the aft of Sierra Space\u2019s Dream Chaser, adding 7,000 lbs. of supplemental cargo capacity to the spaceplane, while its solar arrays and thrusters provide power and additional propulsion to both spacecraft. The acoustic testing at Kennedy Space Center was performed with a mobile setup provided by West Virginia-based Acoustic Research Systems, Inc.; it was the first time onsite acoustic testing has ever been conducted inside the SSPF, NASA\u2019s historic staging location for space station-bound components.<\/p>\n \u201cOur goal is to accurately simulate real world launch conditions to make sure Sierra Space\u2019s Shooting Star cargo module is ready for its first mission to the International Space Station,\u201d said ARS CEO, Jeremiah Leiter.<\/strong> \u201cThe ARS team rose to the challenge, setting up a mobile configuration onsite at Kennedy Space Center \u2013 for the first time ever inside the Space Systems Processing Facility \u2013 providing Sierra Space with critical acoustic qualification testing. We look forward to supporting Sierra Space with the upcoming Dream Chaser acoustic test.\u201d<\/p>\n ARS used a total of 48 acoustic devices during the cargo module testing. The company\u2019s Neutron System is an industry first, consisting of proprietary, purpose-built acoustic devices made for high-output aerospace acoustic testing. ARS will be using an even larger setup for Sierra Space\u2019s Dream Chaser spaceplane; the impending test will be the largest payload ever tested with DFAN.<\/p>\n","protected":false},"excerpt":{"rendered":" Sierra Space, a commercial space company and defense tech prime that is Building a Platform in Space to Benefit Life on Earth, announced the successful completion of acoustic testing on its Shooting Star cargo module at NASA\u2019s Kennedy Space Center, moving the spacecraft a significant step closer to launch readiness.
