Acoustic Buffer Zone

Surrounded by a 125,000-acre acoustical buffer zone, NASA Stennis provides unique services and capabilities to enhance its capacity to meet customer needs and maintain mission success. The buffer zone remains critical to the current and future missions of NASA and the resident agencies and partners at NASA Stennis, and is considered a national asset. Because of this unique asset, NASA Stennis can test large engines or rocket stages 24/7/365, thus minimizing the impact to local communities by loud and low-frequency sound waves produced in the propulsion test complex. The 13,800-acre “fee area” is where day-to-day center operations and business are conducted. Close proximity to highways, interstates, and river access to the Gulf of Mexico make NASA Stennis a perfect logistics location for manufacturing, assembly, and/or testing of various hardware and equipment.
