A NASA technician signs the banner inside a support building at the Launch Equipment Test Facility at Kennedy Space Center in Florida. Testing of the Core Stage Forward Skirt Umbilical (CSFSU) for NASA's Space Launch System is complete and the umbilical has been transported to the mobile launcher area. The umbilical will be prepared for installation on the tower of the mobile launcher. The CSFSU will be mated to the core stage forward skirt to provide commodities to the SLS rocket, and then disconnect and swing away before launch. Its main purpose is to provide conditioned air and gaseous nitrogen to the SLS Core Stage Forward Skirt. The center’s Engineering Directorate and the Ground Systems Development and Operations Program are overseeing processing and testing of the umbilicals.
