Ensuring NASA’s Space Launch System Has the Propulsion It Needs
16 RS-25 engines slated for the first four SLS missions have successfully demonstrated flight worthiness.
- All flight controllers for NASA’s first four SLS flights have successfully completed testing.
- The new RS-25 engine controller, which regulates and monitors engine thrust levels, health and performance, has 20 times the processing capability of the shuttle-era controller.

At the conclusion of the Space Shuttle program, 14 of 16 engines in the SLS inventory had previously flown; two new engines were built from spare components. Last year,
“Generating 512,000 pounds of thrust, the RS-25 engine is a modern marvel, making it the ideal engine to power the SLS,” said
The flight controller is a key component of the RS-25 engine; it serves as the brain of the engine and enables communication between the rocket and the engine, relaying commands and transmitting performance data. Additionally, the controller regulates thrust and fuel mixture ratio while monitoring the engine's overall health and status.

“The excitement is building for the debut flight of SLS,” added Drake. “With today’s test, we are ensuring NASA’s new SLS rocket has the propulsion it needs for future flights carrying humans and cargo to multiple deep space destinations.”
