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 FY2019 NASA appropriations, as well as authorizations for FY2019NASA 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 R44877R45237, Overview of FY2018FY2019 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 CongressSee also CRS In Focus IF10940, The James Webb Space Telescope; CRS In Focus IF10828, The International Space Station (ISS) and the Administration's Proposal to End Direct NASA Funding by 2025; and the discussion of NASA's use of commercial space capabilities in CRS Report R45416, Commercial Space: Federal Regulation, Oversight, and Utilization.

Table 1 shows appropriations for NASA from FY2013 through FY2018. The data for FY2013 through FY2017 include supplemental appropriations, rescissions, transfers, reprogramming, and, in the case of FY2013, sequestration. They are taken from NASA's congressional budget justifications for FY2015 through FY2019.² 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 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 TrumpTable 2 shows FY2018 appropriations, as above; the 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 enacted 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; the Administration's request for FY2019; FY2019 amounts contained in the House Committee on Appropriations committee print dated May 7, 2018, and accompanying draft report; and FY2019 amounts that would be authorized by the NASA Authorization Act of 2018 (H.R. 5503) as ordered reported by the House Committee on Science, Space, and Technology on April 17, 2018. Additional columns will be added to this table as Congress acts on FY2019 authorization and appropriations legislation for NASArequest for FY2019; FY2019 amounts recommended in the 115^th Congress by the House and Senate Committees on Appropriations; FY2019 amounts that would be appropriated by H.R. 21 as passed by the House on January 4, 2019; and FY2019 amounts that would have been authorized by House and Senate authorization bills in the 115^th Congress. The Trump Administration's budget request for FY2019 adopted a new account structure for NASA. Proposed name changes are indicated in the table notes. In addition, the Administration proposed to transfer certain activities from the Deep Space Exploration Systems account (currently Exploration) to the Exploration Research and Technology account (currently Space Technology) so the amounts shown for those items represent somewhat different content in different columns.

Figure 1 shows NASA's total annual budget authority from the agency's establishment in FY1958 to FY2018, in both current dollars and inflation-adjusted FY2018 dollars.
