NASA Appropriations and Authorizations: At a Glance

Updated August 6, 2025 (R43419)

Overview

Congressional deliberations about the National Aeronautics and Space Administration (NASA) often focus on the availability of funding. This fact sheetproduct provides data on past and current NASA appropriations, as well as the President’s FY2025's FY2026 budget request and congressional action on FY2025FY2026 appropriations and authorizationauthorizations of appropriations.

Table 1 shows budget authority for NASA for FY2019-FY2024FY2020-FY2025. Except where noted, the amounts shown include regular appropriations, supplemental, and additional appropriations,; rescissions,; transfers,; and reprogramming. TheyAmounts for FY2020-FY2024 are taken from NASA's congressional budget justifications for FY2021-FY2025;1 the Consolidated Appropriations Act, 2024 (P.L. 118-42); and the explanatory statement for that act, Congressional Record, March 5, 2024, pp. S1141-S1142FY2022-FY2026. Amounts for FY2025 are derived from the Full-Year Continuing Appropriations and Extensions Act, 2025 (P.L. 119-4) and "An Act to provide for reconciliation pursuant to title II of H. Con. Res. 14" (P.L. 119-21). Congressional budget justifications are available on the NASA budget website, https://www.nasa.gov/budgets-plans-and-reports/, for the current year, for FY2026 and for past years back to FY2010.

Table 2 shows FY2024 appropriations provided by the Consolidated Appropriations Act, 2024 (P.L. 118-42), compared with FY2023 regular appropriations as enacted; Table 2 compares FY2025 appropriations, as enacted, with the Administration's request for FY2024; FY2024 appropriations as recommended in the bill introduced by the chair ofFY2026; the draft FY2026 appropriations bill, as approved by the House Appropriations Committee, Subcommittee on Commerce, Justice, Science, and Related Agencies (H.R. 5893 as introduced and explanatory material on the committee website at draft bill text and accompanying report available at https://appropriations.house.gov/sites/republicans.evo-subsites/republicans-appropriations.house.gov/files/FY24-CJS- Explanatory-Materials.pdf); and FY2024 appropriations recommendedevo-media-document/fy26-commerce%2C-justice%2C-science%2C-and-related-agencies-bill-text.pdf and https://docs.house.gov/meetings/AP/AP00/20250724/118544/HMKP-119-AP00-20250724-SD002.pdf, respectively); and FY2026 appropriations as reported by the Senate Committee on Appropriations (S. 2354; S.Rept. 119-44). Additional columns will be added to this table as Congress acts on FY2026 appropriations for NASA. Proposed and enacted authorizations also will be added, if applicable. Table 3 shows FY2024 appropriations provided by the Consolidated Appropriations Act, 2024 (P.L. 118-42), compared with FY2025 appropriations as enacted (P.L. 119-4, P.L. 119-21). It also shows the Administration's request for appropriations for FY2025; FY2025 appropriations as reported by the House Committee on Appropriations (H.R. 9026, S. 2321 as reported and S.Rept. 118-62). Note that the NASA Authorization Act of 2022 (P.L. 117-167, Title VII), which is the most recently enacted authorization, did not include authorizations of appropriations for NASA for FY2024 and beyond.

Table 3 compares FY2024 regular appropriations, as enacted, with the Administration’s request for FY2025; FY2025 appropriations as recommended by the House Appropriations Committee, Subcommittee on Commerce, Justice, Science, and Related Agencies (H.R. 9026 as reported and H.Rept. 118-582); and ); FY2025 appropriations as recommendedreported by the Senate Committee on Appropriations (S. 4795, S.Rept. 118-198). Further, Table 3 contains information on authorizations of appropriations. In particular, it provides FY2025 authorizations of appropriations as passed by the House (H.R. 8958) in the 118th Congress and FY2025 authorizations of appropriations as introduced in the Senate (S. 933) in the 119th Congress. Note that the NASA Authorization Act of 2022 (P.L. 117-167, Title VII), which is the most recently enacted authorization, did not provide authorizations of appropriations beyond FY2023. Figure 1 shows NASA's total annual budget authority from the agency's establishment in FY1958 to FY2025, in both current dollars and inflation-adjusted FY2025 dollars. Table 1.

FY2025 amounts are from P.L. 119-4 and P.L. 119-21. Notes: Except where noted, amounts include regular, supplemental, and additional appropriations; rescissions; transfers;S. 2321 as reported and S.Rept. 118-62); and the FY2025 amounts that would be authorized by H.R. 8958, referred to herein as the NASA Reauthorization Act of 2024, as engrossed in the House on September 23, 2024. Additional columns will be added to this table as Congress acts to complete FY2025 authorization and appropriations legislation for NASA.

A note on name changes: Since the FY2019 budget request, the Trump and Biden Administrations have proposed renaming the Exploration account as “Deep Space Exploration Systems”; enacted appropriations have so far retained the name Exploration. Starting with the FY2023 budget, NASA renamed Exploration Systems Development as “Common Exploration Systems Development,” and Exploration Research and Development (R&D) as “Artemis Campaign Development.” In the FY2025 budget request, NASA renamed Common Exploration Systems Development as “Moon to Mars Transportation System,” and Artemis Campaign Development as “Moon to Mars Lunar Systems Development.”

Figure 1 shows NASA’s total annual budget authority from the agency’s establishment in FY1958 to FY2024, in both current dollars and inflation-adjusted FY2024 dollars.

FY2024 House Introduced: H.R. 5893 as introduced and explanatory material on the House Appropriations Committee website at P.L. 117-328, Division N.

i. P.L. 119-21 includes FY2025 appropriations for several NASA programs and activities. The law does not identify the corresponding account for all of the specified programs, and in some instances, the law includes specific direction that the appropriations may be applied only to a subset of activities in a program. For instance, the law provides $700 million for a "high-performance Mars telecommunications orbiter" and $4.1 billion for the Space Launch System for Artemis Missions IV and V. Therefore, this amount ($9.995 billion) is listed as "Other" in this table.

j. P.L. 119-4, Section 1101, provided FY2025 appropriations at FY2024 regular enacted levels unless otherwise specified. Accordingly, this table shows the enacted amounts for FY2025 as being the same as for FY2024 in P.L. 118-42, Division C, except for the Safety, Security, and Mission Services account, for which P.L. 119-4 specified $3,092 million. P.L. 119-21 provided additional FY2025 appropriations for select NASA programs and activities, for a total of $9.995 billion.

Sources: FY2024 Enacted: P.L. 118-42 and explanatory statement, Congressional Record, March 5, 2024, pp. S1141-S1142. FY2025 Request: FY2025 NASA congressional budget justification. FY2025 House: appropriations recommended by the House Appropriations Committee (H.R. 9026 as reported and H.Rept. 118-582). FY2025 Senate: appropriations recommended by the Senate Appropriations Committee (S. 4795 as reported and S.Rept. 118-198). FY2025 House Authorization:; n/a = not applicable, as the program had not yet been proposed. Additional columns will be added for FY2026 as Congress acts on FY2026 appropriations legislation. a. This is referred to in the FY2026 request as "Moon to Mars Transportation System." b. The FY2026 request proposes creating a Commercial Moon and Mars Infrastructure Development program, which would, if enacted, include both a new program (the Commercial Mars Payload Services program) and some activities currently within the Science Mission Directorate (such as the Commercial Lunar Payload Services program). In addressing the new activities, the FY2026 request states that NASA "will continue to define the content of this new program and will brief Congress as soon as appropriate." c. This is referred to in the FY2026 request as "Moon to Mars Lunar Systems Development." d. With respect to Space Transportation, the report accompanying the draft FY2026 appropriations bill approved by the House Appropriations Subcommittee on Commerce, Justice, Science, and Related Agencies would provide the two major programs within this account (Crew and Cargo, and Commercial Crew) with "no less than the fiscal year 2025 enacted level for both programs." FY2025 enacted appropriations (P.L. 119-4 and P.L. 119-21) do not specify funding levels for these programs. e. The draft FY2026 appropriations bill approved by the House Appropriations Subcommittee on Commerce, Justice, Science, and Related Agencies proposed relocating NASA's EPSCoR and Space Grant programs into the agency's Safety, Security, and Mission Services account.

f. P.L. 119-21 includes FY2025 appropriations for several NASA programs and activities. The law does not identify the corresponding account for all of the specified programs, and in some instances, the law includes specific direction that the appropriations may be applied only to a subset of activities in a program. For instance, the law provides $700 million for a "high-performance Mars telecommunications orbiter" and $4.1 billion for the Space Launch System for Artemis Missions IV and V. Therefore, this amount ($9.995 billion) is listed as "Other" in this table.
