The American Space Museum’s second annual 321 Day celebration will take place this weekend in both Titusville and Eau Gallie. The event honors Robert “Ozzie” Osband, credited as the father of Brevard County’s 321 area code. Festivities in Titusville will occur on Friday from 3 p.m. to 9 p.m., featuring food trucks, local vendors, and music. Eau Gallie’s celebration is Saturday from 11 a.m. to 4 p.m. at Pineapple Park. Both events are free and will celebrate Osband’s legacy and Brevard’s deep ties to the space program.
