# NASA’s SLS (Space Launch System) Resource Reel – December 2025 (SLS-5520)

This resource reel shows major milestones for NASA’s mega Moon rocket, the SLS (Space Launch System) from January 2025 through December 2025. Teams across the country are manufacturing, building, and preparing hardware for SLS rockets that will power the first crewed Artemis missions with Artemis II and III. Video highlights include hardware integration for the SLS rocket to include the stacking of the core stage, two solid rocket boosters, launch vehicle stage adapter, interim cryogenic propulsion stage, and NASA’s Orion spacecraft for Artemis II, as well as the shipment of the Orion stage adapter from NASA’s Marshall Space Flight Center in Huntsville, Alabama, to NASA’s Kennedy Space Center in Cape Canaveral, Florida. Additional highlights feature the transfer of Artemis II’s Orion spacecraft to the Multi-Payload Processing Facility (MPPF), ascent abort scenario training in collaboration with the Department of Defense, and Artemis III hardware fabrication, transport, and processing activities at Michoud, Marshall, and Kennedy.
