Mission-Critical Infrastructure

NASA’s Stennis Space Center is not only the nation’s largest propulsion test center but one of the most unique. It features several large test stands, as well as a highly versatile and unique E Test Complex capable of supporting a range of high-pressure component and engine testing. The center supports a variety of government and commercial test efforts, ranging from high-pressure component test projects. The entire site also is surrounded by a 125,000-acre acoustical buffer zone that is recognized as a national asset and serves as an acoustical buffer zone to enable the possibility of 365/24/7 propulsion activity without disturbing area businesses and residents. By all measures, NASA Stennis stands as the agency’s center for propulsion excellence.
