NASA is one of the world’s largest public science-and-exploration organizations, spanning human spaceflight, space science, Earth observation, aeronautics, and technology development. Below is a data-heavy snapshot of NASA statistics covering funding, workforce, mission volume, and space-station research output.

NASA Statistics (Top Highlights)
- FY 2025 appropriations: $35.6B (includes $24.838B discretionary appropriations and other appropriated components, including mandatory special appropriations).
- FY 2025 budget mix (est.): $17.2B Research, Engineering & Development (49%) and $14.0B Operations (39%), plus Facilities & Equipment and Grants.
- NASA civil service workforce (FY 2025): 17,438 employees.
- Mission volume (FY 2024–FY 2029 manifest): 109 total missions supported in the planning manifest, including 12 crewed and multiple mission categories (categories are not additive).
- ISS research output: 4,000+ investigations and 4,400+ research publications overall, with 361 publications identified for FY 2024 alone.
NASA Funding Statistics
NASA’s FY 2025 Agency Financial Report summarizes $35.6B in appropriations and provides a high-level breakdown of how the budget is categorized (noting the categories are estimates). The chart below shows the four headline budget categories and their relative size.

NASA Mission Statistics
NASA’s FY 2025 budget summary includes a planning manifest for FY 2024–FY 2029 and states that NASA will support 109 total missions over that period. The same summary lists several mission categories (for example, Science and Moon-to-Mars); these categories overlap, so they are not meant to be summed.

International Space Station Research Statistics
NASA reports that ISS research has produced 4,000+ investigations and 4,400+ research publications overall, with 361 publications identified in FY 2024. The chart below uses the reported thresholds (4,000 and 4,400) for scale.
ISS Research Output (Counts)
| Label | Bar | Value |
|---|---|---|
| Research publications (cumulative) | 4,400+ | |
