Located just outside the main gate at Ellsworth Air Force Base, the South Dakota Air and Space Museum tells the stories of not only past aviation but the future of aerospace. There are many different exhibits, one-of-a-kind artifacts and fun-filled activities that showcase the history of those who risked it all for the innovation of aviation and the science of aerospace. The museum is open seven days a week, 8:30 a.m.-6 p.m., June 1-early September (8:30 a.m.-4:30 p.m., early September-May 31).
