Overview

• The proposed $18.8 billion budget represents a $6 billion reduction, the largest single-year cut in NASA's history.
• Key programs like the Mars Sample Return mission, Space Launch System (SLS) rocket, Orion capsule, and Lunar Gateway are set to be canceled.
• NASA's Science Mission Directorate faces a 47% funding cut, significantly impacting Earth Science missions and climate-focused research.
• Despite overall reductions, $7 billion is allocated for crewed lunar exploration and $1 billion for Mars-focused programs, emphasizing competition with China's space ambitions.
• The proposal comes as NASA operates without a confirmed Administrator, raising concerns about leadership and policy coherence during a pivotal moment for U.S. space efforts.
