More About NASA Stennis

NASA’s Stennis Space Center, near Bay St. Louis, Mississippi, is a federal city operated by NASA since 1961. NASA and more than 50 federal, state, academic, public, and private aerospace, technology, and research organizations located onsite share in operating costs, which allows tenants to direct more of their money to individual missions. If their combined workforces of more than 5,200 employees were counted as a single entity, Stennis would rank among the Top 10 Mississippi companies in size. The Stennis Federal City is a major economic engine for the Gulf Coast region, with an average direct annual impact of more than $846 million within a 50-mile radius.
