National Aeronautics and Space Administration (NASA)’s John C. Stennis Space Center is the nation’s largest rocket propulsion test site and a foundational multi-agency federal campus that enables cross-domain collaboration in aerospace, energy, and national security missions. As Mississippi’s most consequential federal asset, Stennis hosts more than 50 resident agencies and companies and supports roughly 6,000 aerospace jobs—establishing the state as a launch-and-test capital for both government and commercial space programs. NASA’s continued investment in Stennis is the catalyst for landmark Mississippi wins like Evolution Space’s relocation to SSC, brokered with MDA and MSET, demonstrating how federal infrastructure converts directly into in-state commercial growth.
