Our Gift Back

For 50 years, the Flandrau Science Center & Planetarium has stood as a public center for scientific wonder and curiosity at the University of Arizona. Born from the vision of U of A astronomers and with the financial assistance of author Grace Flandrau, this establishment opened its doors on December 13, 1975. Since then, Flandrau has brought the beauty of space and science to one of the "astronomy capitals of the world" here in Tucson. From the Hector Vector Star Projector to today's Eos Foundation Planetarium Theater, Flandrau is proud to continue to inspire tomorrow's scientists.
