Preparations for Next Moonwalk Simulations Underway (and Underwater)<\/h1>\n<\/div>\n<\/div>\n<\/div>\n

In 2025, NASA\u2019s Stennis Space Center near Bay St. Louis, Mississippi, marked a year of progress by supporting NASA\u2019s Artemis campaign, celebrating historic milestones, and continuing its role as a trusted propulsion test partner at America\u2019s largest rocket propulsion test site.<\/p>\n

\u201cFor more than six decades, NASA Stennis has proudly represented the Gulf Coast region and America in advancing our nation\u2019s space exploration goals,\u201d said NASA Stennis Director John Bailey. \u201cThis year, we continued our progress forward as we near the launch of Artemis II, while honoring milestones that have brought our center to this point.\u201d<\/p>\n

Supporting Artemis<\/strong><\/h2>\n

As NASA prepares for the launch of Artemis II<\/a> in early 2026, with the first crewed mission to the Moon in over 50 years, NASA Stennis continues its frontline work.<\/p>\n

Every RS-25 engine used to help launch NASA\u2019s SLS (Space Launch System) rocket to the Moon is tested in south Mississippi.<\/p>\n

NASA Stennis teams provided data to lead engines contractor L3Harris Technologies by successfully testing two new production RS-25 flight engines.<\/p>\n

NASA tested RS-25 engine No. 20001 at the Fred Haise Test Stand in June, and RS-25 engine No. 20002 in November. Each engine fired for 500 seconds, reaching 111% of its rated power, while simulating launch conditions.<\/p>\n
