Its federal accounts
Each federal account is one pot of money Congress appropriates, and these are the 12 this agency paid out of, by gross outlays. Each opens on USAspending.gov, which lists its programs and awards.
$22.9B in contracts, grants, loans and direct payments committed in the year. Payments to individuals are published only as totals, so they have a place but no recipient.
Net outlays and the bureau breakdown are the Monthly Treasury Statement’s for September 2025, table 5. Everything else is what National Aeronautics and Space Administration reported to USAspending.gov for fiscal year 2025: its accounts, object classes and functions as gross outlays and obligations, and its contracts, grants, loans and direct payments as award obligations, by the place of performance. Awards are counted under the agency that made them.
