The National Aeronautics and Space Administration (NASA) will celebrate its 50th Anniversary during 2008. Their theme is "NASA @ 50: Exploring for Answers, Powering Our Future." In Ohio, the public is invited to join the NASA Glenn Research Center in our celebration. This is a unique opportunity for visitors of all ages to get a glimpse of what lies behind our gates including the world's largest space environment simulation chamber that has tested parts of rockets, Mars landers and space stations. Enthusiastic NASA staff will guide the public through world-class facilities and share the technologies behind some of the Nation's greatest innovations. Each day will feature activities for kids. And it's all free!
