NASA Conducts Hot Fire of RS-25 Engine

NASA successfully conducted a hot fire of RS-25 engine No. 2063 on Jan. 22 at the Fred Haise Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, clearing the way for the engine to be installed for the agency’s Artemis IV mission. The RS-25 engines help power NASA’s SLS (Space Launch […]

First Hot Fire Test of the Year for Artemis

Clouds of white vapor pile up at NASA’s Stennis Space Center in Bay St. Louis, Mississippi, during a full-duration, 500-second hot fire of an RS-25 certification engine Jan. 17, 2024. This test series is critical for future flights of NASA’s SLS (Space Launch System) rocket in support of the Artemis campaign. During the Jan. 17 […]
