The aft skirt for one of the Space Launch System’s (SLS) two solid rocket boosters is inside the Booster Fabrication Facility at NASA’s Kennedy Space Center in Florida on Oct. 16, 2019. Segments of the boosters are being inspected and prepared for Artemis I, the agency’s first uncrewed flight of Orion atop the SLS. The aft skirts contain the thrust vector control system that steers the booster’s nozzles based on commands from the booster avionics during launch.
