The Boeing-built core stage for NASA’s Space Launch System has moved into High Bay 3 at Kennedy Space Center for stacking and final processing. The core stage will power Artemis III, a mission that will test systems and docking capabilities in low Earth orbit to help prepare for an Artemis IV moon landing in 2028.

Why it matters: The move advances preparations for the third Artemis mission, which will test capabilities needed for a future moon landing.
How it happened: Teams moved the core stage from the Core Stage Vertical Integration Center (CSVIC) into High Bay 3.
- The core stage was raised 225 feet (69 meters) out of the integration center, rotated to a horizontal position and placed on a stand in the Vehicle Assembly Building transfer aisle for final checkouts.
- Teams then lifted it back to a vertical position in High Bay 3, where it is being stacked on the mobile launcher platform.
A faster build approach: Activating the integration center allowed Boeing to streamline the SLS core stage assembly.
- The engine section was installed vertically at Kennedy Space Center in Florida, rather than horizontally at NASA’s Michoud Assembly Facility in Louisiana.
- This was the first core stage shipped from Michoud to Kennedy Space Center without its engine section, enabling vertical integration of the core stage at the center.
What’s next: The core stage will remain in High Bay 3 for stacking and final processing in preparation for a short-stack tanking test later this year and a 2027 launch.
