NASA Glenn Visitor Center is the aerospace gallery inside Great Lakes Science Center and the official public visitor center for NASA’s Cleveland research campus. A real Apollo command module, spaceflight artifacts, and hands-on exhibits explore aeronautics, propulsion, power, materials, and life aboard the International Space Station while connecting them to Glenn’s research legacy. General admission to Great Lakes Science Center includes the NASA Glenn Visitor Center. The host’s current seasonal schedule is Monday–Wednesday 10:00–17:00, Thursday 10:00–20:00, and Friday–Sunday 10:00–17:00 from May through August; from September through April, Monday is closed and Tuesday–Wednesday are 10:00–17:00, Thursday 10:00–20:00, and Friday–Sunday 10:00–17:00. Cleveland Browns home game days can close the Science Center; tickets are available online or at the box office. Use 601 Erieside Avenue, Cleveland, Ohio 44114 for navigation. NASA Glenn’s active research campus is access-controlled and NASA is not currently offering public tours, so this visitor center is the public-facing Glenn experience. The host currently lists general admission at $19.95 for adults and $14.95 for youth ages 2–12, with the NASA Glenn Visitor Center included; members receive free general admission. An attached 500-space garage has a $15 daily maximum, with lower validated rates for members and guests. Check current host hours and Browns home-game closures before travel.
