NASA Tests RS-25 Engine No. 10001 for 500 Seconds

NASA tested RS-25 engine No. 10001 for 500 seconds. The engine was not used in flight.

NASA tested RS-25 engine No. 10001, and the engine was not used in flight.

The listed test sites were the Fred Haise Test Stand and NASA's Stennis Space Center near Bay St. Louis, Mississippi.

The test ran for 500 seconds and recorded a result of 111%, the same value listed for new production engines.

The hot fire test can capture critical data aimed at improving engine performance and reliability.

Stated objectives included acceptance of RS-25 flight components for future Artemis missions and validation of a new thermal protection system; the RS-25 engine nozzle is protected from the thermal environment around SLS during launch.

Operators from NASA, L3Harris, and Nova Space Solutions ran the RS-25 engine tests, with L3Harris Technologies as NASA's prime contractor.

NASA's Stennis Space Center is where RS-25 engines are checked and shown to be ready for flight before use.

4 RS-25 engines launch NASA's SLS rocket used by Artemis missions, and the RS-25 engines have a listed vehicle specification of 2000000 pounds.

For lunar industry tracking, the test connects to Artemis because Artemis missions use the SLS rocket, and 4 RS-25 engines launch each SLS rocket.

NASA's Stennis Space Center is where RS-25 engines are proven flightworthy before use, and the hot fire test captures data to improve engine performance and reliability.
