Kennedy Space Center’s progress this week! Not seen here is that the LETF (Launch Equipment Test Facility) has been proving the umbilical arms can handle the speed and stresses they will be exposed to. A hydraulic lift simulates the upward movement of the SLS as it lifts up and away from the umbilicals. Other testing includes ensuring they retract properly if any parts fail and do not cause any damage to the rocket.
