"NASA Stennis Teams Install New Production RS-25 Engine for Upcoming Hot Fire
NASA marked a key milestone Feb. 18 with installation of RS-25 engine No. E20001, the first new production engine to help power the SLS (Space Launch System) rocket on future Artemis missions to the Moon.
The engine, built by lead SLS engines contractor L3Harris (formerly Aerojet Rocketdyne), was installed on the Fred Haise Test Stand in preparation for acceptance testing next month. It represents the first of 24 new flight engines being built for SLS flights, beginning with Artemis V.
