RS-25 engine upgrade is no 80s techno flashback

December 18th, 2014

The engine controller unit on the RS-25 — formerly known as the space shuttle main engine — helped propel all of the space shuttle missions to space. It allows communication between the vehicle and the engine, relaying commands to the engine and transmitting data back to the vehicle. The controller also provides closed-loop management of the engine by regulating the thrust and fuel mixture ratio while monitoring the engine’s health and status. Just like the ever-evolving computer, the engine controller unit needed a “refresh” to provide the capability necessary for four RS-25 engines to power the core stage of NASA’s new rocket, the Space Launch System (SLS), to deep space missions.
