SLS Tackles Supply Chain and Weld Challenges for Artemis II Core Stage Completion

NASA's Space Launch System (SLS) is working to overcome supply chain issues and weld problems to complete the Core Stage for the Artemis II lunar flyby mission by mid-December. The installation of the four RS-25 core stage engines has been completed, and final assembly and testing are underway. However, delays in the completion of the liquid oxygen tank for the subsequent Core Stage-3 have pushed back its delivery. Despite these challenges, the SLS program aims to complete Core Stage-2 this year and Core Stage-3 by late 2024 or early 2025.
