SLS has deployed seven state-of-the-art Jupiter OLS units to monitor active launch pads, tall towers, and assembly buildings at Kennedy Space Center and Cape Canaveral Space Force Station. The network provides ground-truth data to determine the performance of MERLIN, the 45th Weather Squadron's lightning location network, for lightning strikes to tall structures. Last week, several Jupiter OLS units captured high-speed imagery of a direct strike to the water tower of a major launch pad.
