"Enhanced SLS Rocket Prepares NASA for Artemis Lunar Missions"

NASA is upgrading the Space Launch System (SLS) for its Artemis moon program, with plans for a more powerful Block 1B version to launch in the coming decade for ambitious moon missions, starting with Artemis 4. The upgraded SLS will feature a more powerful second stage and an adapter for large cargos, as well as testing on more powerful RS-25 engines at NASA's Stennis Space Center. The Artemis program aims for a long-term moon settlement near water ice resources, with upcoming crewed missions and the use of an exploration upper stage (EUS) for increased capabilities. NASA is also facing budgetary challenges for fiscal 2025 as it develops Artemis, with administrator Bill Nelson vowing to fight for funding.
