SSC upgrades RS-25 critical system

NASA’s Stennis Space Center (SSC) in Mississippi completed upgrades to a critical system needed to test the RS-25 engines that will power the Space Launch System (SLS) rocket on Artemis missions to the Moon. Engineers and operators on the Fred Haise Test Stand completed testing of the thrust vector (TVC) system needed to gimbal RS-25 engines during testing. Gimbaling is the term for moving an engine a few degrees along a tight circular axis to direct the thrust and “steer” the SLS rocket on a proper trajectory during launch. The upgrades were performed to increase the speed of the actuators in returning an engine from a gimbaled angle back to the null position with the engine pointing directly down. Stennis Space Center, located near Bay St. Louis, is preparing to conduct certification tests for production of new RS-25 engines for future Artemis missions.
