A crane lifts the Interim Cryogenic Propulsive Stage Umbilical (ICPSU) arm for NASA’s Space Launch System at the Launch Equipment Test Facility at Kennedy Space Center in Florida.

The ICPSU is one of the umbilical arms that will be attached to the mobile launcher. The umbilical will be located at the about the 240-foot-level of the mobile launcher and will supply fuel, oxidizer, pneumatics, hazard gas leak detection, electrical commodities and environmental control systems to the interim cryogenic propulsive stage of the SLS rocket during launch.
