For my accompanying blog, see “NASA’s (really) declining budget,” April 8, 2021.

Notes:
- 2021 Bio/Phys. Sci. moved from ISS R&D to Sci. line. (Not one for one; ISS R&D drop 2X larger than new line)
- Commercial LEO 2020 $15M, 2021 $17M
- Applies the latest 2022 NASA Inflation Tables. General US Inflation for 2021=7.0%, 2022=7.9% as of March 2022. But note that NASA’s updated indices for these years are 3.8% & 5.7% resp.
…and a comparison of inflation indexes

Notes:
- A dollar in 1995, using the general US inflation indexes, would require $1.93 today for the same purchasing power, or using the NASA inflation indexes, $2.03. Overall there is not much difference between the indices. NASA would need about $2 in 2022 to purchase what $1 purchased in 1995. NASA’s 2022 budget is less than this equivalent purchasing power. NASA’s budget, to have the same purchasing power in 2022 as in 1995, would be about $28.7 billion, but it is actually about $24 billion, or 16% less.
- The largest deviation between the indices occurs in 2022.
- Watch for updates.
