Inside the Booster Fabrication Facility at NASA’s Kennedy Space Center in Florida, the Artemis I aft skirts for the agency’s Space Launch System (SLS) rocket’s twin solid rocket boosters are being readied for their move to the Rotation, Processing and Surge Facility (RPSF). In view, the left aft skirt assembly is attached to a move vehicle and moved out of a test cell. The aft skirts were refurbished by Northrop Grumman. They house the thrust vector control system, which controls 70 percent of the steering during initial ascent of the SLS rocket. The segments will remain in the RPSF until ready for stacking with the forward and aft parts of the booster on the mobile launcher in High Bay 3 of the Vehicle Assembly Building.
