Overview
Congressional deliberations about the National Aeronautics and Space Administration (NASA)
often focus on the availability of funding. This fact sheet provides data on past and current NASA
appropriations, as wel as the President’s budget request for FY2022 and congressional action on
FY2022 appropriations and authorizations of appropriations. In FY2022 through December 3,
2021, NASA is operating at FY2021 funding levels under a continuing resolution (P.L. 117-43).
Table 1 shows budget authority for NASA for FY2015-FY2021. Except where noted, the
amounts shown include regular appropriations, supplemental appropriations, rescissions,
transfers, and reprogramming. They are taken from NASA’s congressional budget justifications
for FY2017-FY2022.1 Congressional budget justifications are available on the NASA budget
website (http://www.nasa.gov/news/budget/) for the current year and for past years back to
FY2002.
Table 2 shows FY2021 appropriations as enacted (before the transfers and reprogramming
reflected in Table 1); the Administration’s request for FY2022; FY2022 appropriations
recommended by the House Committee on Appropriations (H.R. 4505 as reported and H.Rept.
117-97); FY2022 appropriations recommended in the majority draft bil and report released by
the Senate Committee on Appropriations on October 18, 2021; and supplemental funding for
hurricane damage repair provided in the continuing resolution. Additional information wil be
added as Congress continues to act on FY2022 appropriations and authorizations. Note that the
NASA Authorization Act of 2021 (S. 1260, Title VI, Subtitle B) does not include authorizations
of appropriations for NASA for FY2022.
A note on name changes: In FY2019, the Education account was renamed as Science,
Technology, Engineering, and Mathematics (STEM) Engagement. Since the FY2019 budget
request, the Trump and Biden Administrations have proposed renaming the Exploration account
as Deep Space Exploration Systems. Enacted appropriations have so far retained the name
Exploration. The Trump Administration budget requests for FY2019-FY2021 also proposed new
names for the Space Technology and Space Operations accounts. Enacted appropriations retained
the current names, which are also used in the Biden Administration budget request for FY2022.
Figure 1 shows NASA’s total annual budget authority from the agency’s establishment in
FY1958 to FY2021, in both current dollars and inflation-adjusted FY2021 dollars.

1 FY2016, FY2017, and FY2019 Education and ST EM Engagement amounts are not shown in the FY2018, FY2019,
and FY2021 congressional budget justifications and are instead taken from the explanatory statement for the
Consolidated Appropriations Act, 2016 (P.L. 114-113), Congressional Record, December 17, 2015, pp. H9741-H9743;
the explanatory statement for the Consolidated Appropriations Act, 2017 ( P.L. 115-31), Congressional Record, May 3,
2017, pp. H3374-H3375; and the explanatory statement for the Consolidated Appropriations Act, 2020 ( P.L. 116-93),
Congressional Record, December 17, 2019, pp. H10969-H10971.
