A crane moves the Core State Inter-tank Umbilical (CSITU) for NASA's Space Launch System (SLS) closer for attachment to the "C" tower of the Vehicle Motion Simulator 2 test fixture at the Launch Equipment Test Facility at the agency's Kennedy Space Center in Florida. The umbilical will undergo a series of tests to confirm it is functioning properly and ready to support the SLS rocket for launch. The CSITU is a swing arm umbilical that will connect to the SLS core stage inter-tank. The umbilical's main function is to vent gaseous hydrogen from the core stage. The arm also provides conditioned air, pressurized gases, and power and data connection to the core stage. The center’s Engineering Directorate and the Ground Systems Development and Operations Program are overseeing processing and testing of the umbilicals.
