The Fleet Science Center (previously the 'Reuben H. Fleet Science Center') is a science museum and planetarium in Balboa Park, located in San Diego, California. It is at the east end of the El Prado Drive walkway, next to the Bea Evenson Fountain and plaza in central Balboa Park. Established in 1973, it was the first science museum to combine interactive science exhibits with a planetarium and an IMAX Dome (OMNIMAX) theater, setting the standard that most major science museums follow today.
