The NASA budget since 1995

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

I made some minor refinements in the data on June 17, 2021.

The NASA purchase power drop since 1995 = 19%. Updated through the actual budget approved by Congress for 2021.


  1. 2021 Biological/Physical Science moved from inside ISS R&D to Science line. (Not one for one; ISS R&D drop 2X larger than new line)
  2. Commercial LEO 2020 $15M, 2021 $17M
