NASA’s Stennis Space Center in Mississippi has been busy preparing for the upcoming Artemis II mission, set to launch in early 2026. This mission will mark the first crewed mission to the Moon in over 50 years. At Stennis, every RS-25 engine used to launch NASA’s SLS rocket is tested. Recently, the teams successfully tested two new production RS-25 flight engines, with each engine firing for 500 seconds and reaching 111% of its rated power under simulated launch conditions.
The center’s work is crucial in supporting NASA’s Artemis campaign, and it plays a significant role as a trusted propulsion test partner at America’s largest rocket propulsion test site. NASA Stennis Director John Bailey highlighted the center’s progress and the milestones achieved, emphasizing its contribution to advancing the nation’s space exploration goals. The successful testing of these engines brings NASA one step closer to the groundbreaking Artemis II mission.
