NASA conducts 5th RS-25 series test at Stennis Space Center

HANCOCK COUNTY, Mississippi (WJTV) – On Wednesday, NASA conducted a fifth single-engine RS-25 hot shot, part of its ongoing seven-part test series, supporting the development and production of engines for the system space launch vehicle (SLS) during future missions to the moon.

Operators fired the engine for more than eight minutes on the A-1 test stand at Stennis Space Center in Hancock County, providing data to Aerojet Rocketdyne, prime contractor for SLS engines, as it produces engines at use after the first four SLS flights.

With testing of the RS-25 engines for the first four missions of the Artemis program to the Moon having been completed, NASA officials said operators are now focusing on collecting data to demonstrate and verify the engine’s various capabilities, assess new engine components manufactured with advanced and economical technologies. technologies and reduce operational risk.

In Wednesday’s test, the team fired the engine at 111% of its original power level for a set amount of time, the same level RS-25 engines are expected to run during launch, as well as 113% , which allowed operators to test a safety margin.

NASA is building SLS as the world’s most powerful rocket to send the agency’s Orion spacecraft to the moon as part of Artemis.
