NASA successfully integrated the core stage of the Space Launch System (SLS) rocket at Kennedy Space Center in Florida on March 23, 2025. This achievement marks a critical step towards launching the first crewed mission under NASA’s Artemis program.
The core stage is a crucial component of the SLS rocket, supporting the launch vehicle stage adapter, interim cryogenic propulsion stage, Orion stage adapter, and the Orion spacecraft. The integration process involved using one of the five overhead cranes at Kennedy’s Vehicle Assembly Building to lift and place the core stage between the solid rocket boosters.
The next phase will involve adding the Orion stage adapter, which will be secured atop the core stage in the coming weeks. This step is essential for completing the structure that will support the Orion spacecraft during its journey to the Moon.
The Artemis II mission aims to establish sustainable human exploration on the Moon by the mid-2020s and eventually send astronauts to Mars. The 10-day orbital test flight around the Moon will confirm the functionality and safety of the entire spacecraft and launch vehicle, providing critical data for future human missions.
With the core stage integration complete, NASA engineers and ground systems teams will continue to work meticulously to prepare the spacecraft and rocket for flight. Final preparations include integrating the cryogenic propulsion stage, performing engine tests, and ensuring the performance of key SLS systems. Once completed, the Artemis II mission will be ready for launch, marking a major step in humanity’s efforts to return to the Moon and beyond.
