NASA is targeting Wednesday, Oct. 14 for its next RS‑25 engine hot fire test on the Fred Haise Test Stand at NASA Stennis. The test window is between 2 to 4 p.m. CDT, and you are invited to watch live! As we approach ignition, an update will be provided. For each @NASAArtemis mission, four RS-25 engines, along with a pair of solid rocket boosters, power NASA’s SLS (Space Launch System) rocket to produce more than 8.8 million pounds of total combined thrust at liftoff. 🔥 Watch the test here: ➡️ youtube.com/NASAStennis ➡️ facebook.com/NASAStennis

Celebrating 65 Years: The 2020s On October 25, 2026, we hit a major milestone – 65 years since NASA announced it would build a rocket propulsion test site in Hancock County, Mississippi. History is still being written today as NASA progresses forward with the Artemis program to return American astronauts to the Moon and build a Moon Base to support an enduring human presence on the lunar surface. This look back at the 2020s features: ➡️ Supporting work for NASA’s Artemis program ➡️ Infrastructure upgrades ➡️NASA Administrator Jared Isaacman’s first visit to NASA Stennis

Go behind the scenes of an RS-25 engine install day! On Sept. 29, teams successfully lifted and installed developmental engine No. 10001 on the Fred Haise Test Stand at NASA Stennis for an upcoming hot fire test. In this video, Josh Greiner, test director for the stand, shares more about what a developmental engine is and how testing supports @NASAArtemis missions. Watch the process unfold! ⬇️

Kristie Foster paved her road to becoming a NASA civil servant with literal miles of dedication. Her work at the agency’s Stennis Space Center near Bay St. Louis, Mississippi, supports NASA’s mission to return American astronauts to the Moon, build a Moon Base for an enduring presence on the lunar surface, and ensure American leadership in space. Foster’s move from a long-time contractor to a civil servant secures critical institutional knowledge after being hired in June under the agency’s workforce directive to restore core competencies. 🔗Full story: nasa.gov/centers-and-facilit…
