NASA's FY 2025 Budget

NASA's budget in fiscal year (FY) 2025 was $24.8 billion, equivalent to what the agency received in 2024.

President Biden's White House had requested $25.4 billion, a 2% increase, had it been enacted.

However, due to political gridlock after the 2024 fall elections, Congress delayed consideration of appropriations legislation, opting instead for a series of continuing resolutions (CRs), which temporarily extended prior year funding levels.

On March 15, 2025, halfway through the fiscal year, Congress abandoned efforts to pass appropriations and opted for a full-year continuing resolution, which provided NASA with a top-line funding amount of approximately $24.8 billion.

The President's FY 2025 Budget Request for NASA

Highlights from the President's FY 2025 Budget Request included:
 

• NASA's Planetary Science Division flat at $2.7 billion — a $500 million cut from 2023
  Congress cut the division's budget to $2.7 billion in FY2024 in response to MSR's troubles. The Biden Administration would have extended that cut into 2025.
• Mars Sample Return (MSR) remained in programmatic limbo
  Pending a decision on a reimagined project, MSR funding was proposed at $200 million to maintain NASA's essential workforce.
• The VERITAS mission to Venus was restored with a 2031 launch date
  VERITAS had been indefinitely delayed in 2023. It is now replanned to launch in 2031.
• DAVINCI was delayed to the same 2031 launch window
• The Geospace Dynamics Constellation was proposed to be canceled
  This high-priority Heliophysics flagship was proposed to be canceled due to budget constraints.
• Artemis funding was flat
  At 7.6 billion, the request was similar to FY2024's congressional appropriation.

Congressional Activity

On June 26, 2024, the House of Representatives' Commerce, Justice, and Science Subcommittee (CJS) of Appropriations released its draft NASA budget for FY 2025. The full appropriations committee subsequently approved it on July 9, 2024.

The House provided a 1% increase to NASA’s budget relative to 2024, which was less than the 2% proposed by the White House. Funding for the Science Directorate remained flat, with the increases primarily benefiting NASA’s Space Operations and Space Technology directorates.

Within the limited Science budget, the House did provide a $200 million increase to the Planetary Science Division, primarily at the expense of Earth Science. The House was set to appropriate $650 million for the troubled Mars Sample Return program, which was undergoing significant re-evaluation, including the consideration of commercial partnerships. NASA had requested $200 million for 2025. The difference—$450 million—was partially offset by the PSD top-line increase. However, neither the legislative text nor the associated committee report addressed how the Planetary Science Division would absorb the $250 million shortfall. Given committee direction supporting NEO Surveyor and the Commercial Lunar Payload Services program, there were only a handful of programs that could have been cut (and cut severely) to accommodate this additional spending: Dragonfly to Titan, the two Venus Discovery missions in early development, fundamental scientific research, and Radioisotope Power Systems would all have been targets had this bill passed as-is.

The Senate's CJS appropriations subcommittee released its draft NASA budget on July 25, 2024, though the full Senate never voted on the measure. The Senate's bill tracked more closely to the President's budget request, and maintained a low funding profile for Mars Sample Return. 

The U.S. national elections sidelined further progress on appropriations. While Congress nearly approved a broad government funding package in December 2024, the votes did not materialize, and the U.S. government was provided a further continuing resolution into the spring of the following year.

Congress ultimately opted to pass a full-year continuing resolution in March of 2025, nearly six months into the fiscal year. While the final bill had a number of directives to U.S. agencies, NASA received only a single specific mention: to provide $3.092 billion for Safety, Security, and Mission Services, approximately $50 million below the FY 2024 level but $48 million above the White House's request. NASA's top-line funding level stayed flat at $24.8 billion for the 2025 fiscal year.

H.R. 1, the "One Big Beautiful Bill Act" (OBBA)

In July 2025, Congress passed H.R. 1, a spending package that included an unexpected windfall for NASA's human spaceflight activities.

The bill appropriated $9.995 billion for NASA in FY 2025 outside of the normal appropriations process, primarily for use over the following seven years. The funds were directed primarily toward human spaceflight programs: $4.1 billion for Space Launch System production for Artemis IV and V, $2.6 billion for the Lunar Gateway, $1.25 billion for International Space Station operations, and $1 billion for infrastructure improvements at NASA's human spaceflight centers.

Of this total, only the $250 million for ISS operations carried an FY 2025 obligation requirement. The remaining funds are directed to be spent on an annual basis starting in FY 2026, with at least 50% obligated by September 30, 2028, and 100% by September 30, 2029.
