STENNIS, Miss. - NASA conducted the first hot fire of a new RS-25 test series Oct. 17, beginning the final round of certification testing ahead of production of an updated set of the engines for the Space Launch System (SLS) rocket.
The engines will help power future Artemis missions to the Moon and beyond.
NASA completed a full duration, 550-second hot fire of the RS-25 certification engine.
Operators fired the RS-25 engine for more than nine minutes, longer than the 500 seconds engines must fire during an actual mission, on the Fred Haise Test Stand at NASA’s Stennis Space Center in Mississippi.
Operators also fired the engine up to the 111% power level needed during an SLS launch.
The hot fire marked the first in a series of 12 tests scheduled to stretch into 2024.
The tests are a key step for lead SLS engines contractor Aerojet Rocketdyne, an L3Harris Technologies company, to produce engines that will help power the SLS rocket, beginning with Artemis V. (NASA 10/17/23) NASA Conducts 1st Hot Fire of New RS-25 Certification Test Series - NASA
