NASA Stennis Achieves Milestone in Preparation for Future Artemis Testing

Teams at NASA’s Stennis Space Center complete a safe lift and install of an interstage simulator unit needed for future testing of NASA’s exploration upper stage (EUS) in the B-2 position of the Thad Cochran Test Stand. The lift and install, completed over a two-week period that began Oct. 10, marks a milestone for testing the new SLS (Space Launch System) rocket stage that will fly on future Artemis missions to the Moon and beyond. The EUS will undergo a series of Green Run tests of its integrated systems prior to its first flight. During testing, the interstage simulator component will function like the SLS interstage section that helps protect the upper stage during Artemis launches.
