Congressional deliberations about the National Aeronautics and Space Administration (NASA) often focus on the availability of funding. This fact sheet provides data on past, current, and proposed NASA appropriations. No bills have yet been introduced in the 115^th Congress proposing future-year authorizations of NASA appropriations.

Additional information on appropriations legislation affecting NASA is provided in CRS Report R44877, Overview of FY2018 Appropriations for Commerce, Justice, Science, and Related Agencies (CJS) and similar reports for prior years.¹ NASA issues of congressional interest are discussed further in CRS Report R43144, NASA: Issues for Authorization, Appropriations, and Oversight in the 114th Congress.

Table 1 shows appropriations for NASA from FY2012FY2013 through FY2017FY2018. The data for FY2012FY2013 through FY2016 include supplemental appropriations, rescissions, transfers, reprogramming, and, in the case of FY2013, sequestration. They are taken from NASA's congressional budget justifications for FY2014 through FY2018.² 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. The table data for FY2017 are as enacted by the Consolidated Appropriations Act, 2017 (P.L. 115-31). For amounts not specified in that act, see pp.pages H3374-H3375 of the explanatory statement, published in the Congressional Record on May 3, 2017.

Table 2 shows enacted appropriations for FY2017 (as above); the Administration's request for FY2018; the House Committee on Appropriations recommendations for FY2018, as contained in H.R. 3267 as reported and H.Rept. 115-231 as well as H.R. 3354 as passed by the House; and the Senate Committee on Appropriations recommendations for FY2018, as contained in S. 1662 as reported and S.Rept. 115-139.

The Continuing Appropriations Act, 2018 (Division D of P.L. 115-56), as amended, provides FY2018 continuing appropriations for NASA until January 19, 2018. The rate is based on the level of FY2017 appropriations—not including $109 million in FY2017 emergency appropriations (see note to Table 2)—reduced by 0.6791% The table data for FY2018 are as enacted by the Consolidated Appropriations Act, 2018 (P.L. 115-141). For amounts not specified in that act, see pages H2094-H2096 of the explanatory statement, published in the Congressional Record on March 22, 2018. The Trump Administration's budget request for FY2019 adopted a new account structure for NASA. It presented FY2017 amounts adjusted for comparability with the new structure, but not FY2018 amounts, because final FY2018 appropriations had not yet been enacted at the time the FY2019 budget was released. Table 2 shows FY2017 appropriations, adjusted for comparability, and the Administration's request for FY2019. Additional columns will be added to this table as Congress acts on FY2019 authorization and appropriations legislation for NASA.

Figure 1 shows NASA's total annual budget authority from the agency's establishment in FY1958 to FY2017FY2018, in both current dollars and inflation-adjusted FY2017FY2018 dollars.
