INFINITY Science Center is a nonprofit Gulf Coast Earth-and-space science museum and NASA’s official public visitor center for Stennis Space Center. Its 35,000-square-foot experience combines Earth and Space Galleries, the Natrium, Engineering Workshop, environmental and hurricane exhibits, Apollo-era engines, the Apollo 4 command module, Saturn V S-IC-15 stage, a walk-through International Space Station Destiny mock-up, rocket and spaceflight artifacts, an RS-25 test-conductor simulator, a 3D Immersive Theater and outdoor habitat exhibits. Stennis is an active rocket-propulsion test site; regular bus tours from INFINITY are no longer available, and only separately announced public events may offer a windshield visit, so do not assume museum admission includes the secure center. Check current operator hours, admission, exhibit/program availability and event notices before travel. Detailed accessibility provisions are not published; contact INFINITY ahead if support is needed. Visitor address: One Discovery Circle, Pearlington, Mississippi 39572, United States.
