"With today's test, the RS-25 development and flight engines have experienced 6,848 seconds of SLS test time," said
One of the most significant RS-25 engine improvements for SLS is an upgraded engine controller to implement modern electronic designs and processes for greater capabilities and reliability. The controller is critical for executing engine command and control, and tracking the RS-25 engines' operating conditions, such as the speed of the turbopumps, combustion temperatures, thrust and propellant mixture ratio.
