Service Structure
Launch Complex 39's Pad A was originally designed to support the Apollo program and were modified for Space Shuttle launch operations. Major changes included the erection of a new Fixed Service Structure (FSS) and a Rotating Service Structure (RSS).
The FSS is topped by a 80ft tall fiberglass lightning mast grounded by 1,100ft cables that are anchored north and south of the pad.
