The Senate Appropriations Committee released a fiscal 2027 funding proposal on November 12, 2026, recommending approximately US$24.87 billion for NASA. The proposed total is $435.9 million above the fiscal 2026 enacted level, according to the committee’s explanatory statement.
NASA’s funding appears in the Commerce, Justice, Science, and Related Agencies package, one of five spending bills included in the committee’s November 12 release. The documents present proposed appropriations and accompanying program direction for the fiscal year ending September 30, 2027.
The proposal combines funding for scientific missions and human exploration with allocations for technology development, operations, facilities, and personnel. Its exact recommended agency total is $24,874,196,865, compared with $24,438,336,000 in enacted fiscal 2026 appropriations.
Funding Across NASA Accounts
The proposed bill text allocates $7.43 billion to science, $8.282 billion to exploration, and $4.125 billion to space operations. It also proposes $825 million for space technology and $910 million for aeronautics.
These accounts support different activities. Science funding covers research and scientific spacecraft. Exploration supports the systems and activities used for human missions beyond low Earth orbit. Space operations supports operational spaceflight activities and related services. The bill describes research, development, operations, personnel, spacecraft control, and communications among the uses of NASA appropriations.
Within space technology, the draft specifies $110 million for the development, production, and demonstration of nuclear-propulsion systems. That is a designated portion of the proposed technology account.
The draft makes the science, aeronautics, and space-technology appropriations available through September 30, 2028. Such availability provisions define the period during which NASA could commit the money under the proposed legislation, even though the appropriation belongs to the fiscal 2027 funding package.
Scientific Allocations and Mars Sample Return
The explanatory statement divides the proposed science total into $2.1879 billion for Earth science, $2.6172 billion for planetary science, $1.6566 billion for astrophysics, $880.3 million for heliophysics, and $88 million for biological and physical science.
Its Mars Sample Return language supports returning material for scientific study and demonstrating capabilities applicable to future human Mars missions. The committee proposes integrating that work into NASA’s Moon-to-Mars architecture. The statement connects the sample-return effort with both robotic science and human-exploration technology.
The bill and statement operate at different levels of detail. The bill supplies account amounts and legislative conditions. The statement describes recommended allocations and congressional expectations within those accounts. Reading them together identifies both the proposed funding level and the activities to which appropriators intend it to apply.
A Congressional Proposal Distinct From the Budget Request
NASA’s fiscal 2027 budget materials present the administration’s requested funding. The committee’s November package is a separate congressional proposal within the annual appropriations process.
New Space Economy’s earlier federal civil-space budget review explains the distinction among requested funding, enacted appropriations, contractual commitments, and payments. A requested budget states a proposed allocation; an appropriation provides spending authority when enacted. A contract obligation and a cash payment occur at subsequent stages.
That distinction also separates annual appropriations from previously enacted funding available over several years. The committee’s stated comparison is with NASA’s fiscal 2026 annual appropriation. The November 12 release supplies the bill, explanatory statement, and summary for the next stage of congressional consideration.
