Key Takeaways:

The White House's FY2026 budget proposes a substantial 25% reduction in NASA's overall funding, cutting it from $25 billion to $18.8 billion.
This budget prioritizes human space exploration, directing increased investments towards lunar and Mars missions while significantly reducing funding for science, technology, and legacy programs.
Key initiatives like the Mars Sample Return mission face termination, and costly systems such as the Space Launch System (SLS) and Orion capsule are slated to be phased out after Artemis III.
The proposed cuts have drawn strong opposition from science and industry groups, who warn of chaos, waste, and a potential loss of American leadership in space science and exploration.

The White House on Friday released its fiscal year 2026 discretionary budget request, proposing a dramatic reduction in NASA’s overall funding from about $25 billion to $18.8 billion, or about 25 percent. But not all programs will be affected equally.

The discretionary or “skinny” budget is akin to a blueprint and is an early step in the process. It could change as it moves through the legislature. But the initial proposal props up NASA human space exploration while casting a dark shadow over the space agency’s science and other programs. The Mars Sample Return mission, Space Launch System rocket, Orion capsule, and Gateway space station all face impacts from cuts to their respective programs.
