Week in Space Data, every Friday.
What Washington asked for, what it enacted, and the prior-year level (NASA, Space Force and NOAA, line by line), plus the bills and markups that decide the numbers. Amounts in USD millions.
This table is hand-checked against the FY2026 President's Budget Request, the enacted appropriations and committee records, with a source link on every line (last checked October 9, 2026): it is not a live feed. Filter and export it on the interactive budget tracker or the congressional tracker.

Totals sum the tracked top-level lines only, so they are smaller than each agency's full topline; sub-lines (SLS, Orion and HLS inside Exploration, SBIR/STTR inside Space Technology) are not added twice. Enacted is blank where the enacted law sets no figure for a line.
| Exploration (account) Exploration | NASA | 2025 | $7.62B | $7.67B | $7.67B | -0.6% | FY2025 NASA was funded by a full-year continuing resolution (P.L. 119-4) at FY2024 levels. The request account name was Deep Space Exploration Systems. Prior year is the FY2024 enacted level; the change is request vs that level. |
| Operation and Maintenance, Space Force (account total) Operations & Maintenance | Space Force | 2026 | $5.89B | $5.69B | $5.04B | +16.7% | Discretionary O&M request; plus $22.2M reconciliation (total $5,910.3M). Prior year is the FY2025 enacted level from the FY2026 O-1. |
| Planetary Science Science | NASA | 2025 | $2.73B | – | $2.76B | -1.2% | The full-year CR (P.L. 119-4) set no Planetary Science level; NASA's FY2025 spending plan shows about $2,728M (CRS R43419). Prior year is the FY2024 operating plan (the FY2025 full-year CR set no level for this line), so the change spans two years. |
| Resilient Missile Warning/Tracking Space RDT&E | Space Force | 2026 | $2.44B | $2.37B | $2.45B | -0.4% | RDT&E PEs 1206446SF LEO $1,757.4M and 1206447SF MEO $686.3M (discretionary).
