As a federal agency, the National Aeronautics and Space Administration (NASA) receives its funding from the annualfederal budget passed by theUnited States Congress. The following charts detail the amount of federal funding allotted to NASA each year over its history to pursue programs inaeronautics research, roboticspaceflight, technology development, and humanspace exploration programs.

NASA's budget for fiscal year (FY) 2024 is $25.4 billion.^[1] It represents 0.37% of the $6.8 trillion the United States spent that year.^[2] Due to a full-yearcontinuing resolution^[3], NASA's FY2025 budget is the same as FY2024.

In May 2025, during thesecond Donald Trump administration, the FY2026 budget request was released, proposing a radical 24% cut to its overall budget and the smallest since 1961.^[4] Despite political opposition, the cuts are being implemented through staff reductions.^[5]

Since its inception, the United States has spent over $1.8 trillion^[6] (in 2024 dollars) on NASA.

Notes

• The budget dollar values refer to the specific appropriations provided by congress to NASA. It may differ slightly to the total outlay (real expenditure) of funds allocated to NASA.
• Data for this table collected by The Planetary Society^[6].

NASA's budget peaked in 1964–66 when it consumed roughly 4% of all federal spending. The agency was building up to the first Moon landing and theApollo program was a top national priority, consuming more than half of NASA's budget and driving NASA's workforce to more than 34,000 employees and 375,000 contractors fromindustry and academia.^[7]

In 1973, NASA submitted congressional testimony reporting the total cost of Project Apollo as $25.4 billion (about $187 billion in 2024 dollars).^[8]

A November 1971 study of NASA released byMRIGlobal (formerly Midwest Research Institute) ofKansas City,Missouri concluded that "the $25 billion in 1958 dollars spent on civilian space R & D during the 1958–1969 period has returned $52 billion through 1971 – and will continue to produce payoffs through 1987, at which time the total pay-off will have been $181 billion. The discounted rate of return for this investment will have been 33 percent."^[9]

Other statistics on NASA's economic impact may be found in the 1976 Chase Econometrics Associates, Inc. reports^[10] and backed by the 1989 Chapman Research report, which examined 259 non-space applications of NASA technology during an eight-year period (1976–1984) and found more than:

• $21.6 billion in sales and benefits
• 352,000 (mostly skilled) jobs created or saved
• $355 million in federal corporate income taxes

According to a 1992Nature commentary, these 259 applications represent ". . .only 1% of an estimated 25,000 to 30,000 Space program spin-offs."^[11]

A 2013 report prepared by the Tauri Group for NASA showed that NASA invested nearly $5 billion in U.S. manufacturing in FY 2012, with nearly $2 billion of that going to the technology sector. NASA also develops and commercializes technology, some of which can generate over $1 billion in revenue per year over multiple years^[12]

In 2014, theAmerican Helicopter Society criticized NASA and the government for reducing the annualrotorcraft budget from $50 million in 2000 to $23 million in 2013, impacting commercial opportunities.^[13]

The 2017 Economic Impact Report prepared by NASA for theirSmall Business Innovation Research (SBIR) andSmall Business Technology Transfer (STTR) awards found that for FY 2016, these programs created 2,412 jobs, $474 million in economic output, and $57.3 million in fiscal impact with an initial investment of $172.9 million.^[14]

The perceivednational security threat posed by earlySoviet leads in spaceflight drove NASA's budget to its peak, both in real inflation-adjusted dollars and in a percentage of the total federal budget (4.41% in 1966). But the apparent U.S. victory in theSpace Race — landing men on the Moon — erased the perceived threat, and NASA was unable to sustain political support for its vision of an even more ambitiousSpace Transportation System entailingreusable Earth-to-orbit shuttles, a permanentspace station,lunar bases, and ahuman mission to Mars. Only a scaled-back space shuttle was approved, and NASA's funding leveled off at just under 1% in 1976, then declined to 0.75% in 1986. After a brief increase to 1.01% in 1992, it declined to about 0.5% in 2013.

To help with public perception and to raise awareness regarding the widespread benefits of NASA-funded programs and technologies, NASA instituted theSpinoffs publication. This was a direct offshoot of the Technology Utilization Program Report, a "publication dedicated to informing the scientific community about available NASA technologies, and ongoing requests received for supporting information." according to the NASA Spinoff about page the technologies in these reports created interest in the technology transfer concept, its successes, and its use as a public awareness tool. The reports generated such keen interest by the public that NASA decided to make them into an attractive publication. Thus, the first four-color edition of Spinoff was published in 1976.^[15]

The American public, on average, believes NASA's budget has a much larger share of the federal budget than it actually does. A 1997 poll reported that Americans had an average estimate of 20% for NASA's share of the federal budget, far higher than the actual 0.5% to under 1% that has been maintained throughout the late '90s and first decade of the 2000s.^[16] It is estimated that most Americans spent less than $9 on NASA through personal income tax in 2009.^[17]

However, there has been a recent movement to communicate discrepancy between perception and reality of NASA's budget as well as lobbying to return the funding back to the 1970–1990 level. TheUnited States Senate Science Committee met in March 2012 where astrophysicistNeil deGrasse Tyson testified that "Right now, NASA's annual budget is half a penny on your tax dollar. For twice that—a penny on a dollar—we can transform the country from a sullen, dispirited nation, weary of economic struggle, to one where it has reclaimed its 20th-century birthright to dream of tomorrow."^[18][19] Inspired by Tyson's advocacy and remarks, thePenny4NASA campaign was initiated in 2012 by John Zeller and advocates the doubling of NASA's budget to one percent of the Federal Budget, or one "penny on the dollar."^[20]

In 2018,Business Insider surveyed approximately 1,000 US residents to determine what they believed was the annual NASA budget. The average respondent estimated that NASA's budget was 6.4% of annual federal spending, when it was actually 0.5%. In a follow-up question, 85% of respondents stated that NASA funding should be increased, despite the majority of responses overestimating NASA's actual budget.^[21]

NASA's cost overruns and time delays have been blamed by some on NASA's usage ofcost-plus contracts and avoidance offixed-price contracts.^[22]

Public opposition to NASA and its budget dates back to the Apollo era. Critics have cited more immediate concerns, like social welfare programs, as reasons to cut funding to the agency.^[23] Furthermore, they have questioned thereturn on investment (ROI) feasibility of NASA's research and development. In 1968, physicistRalph Lapp argued that if NASA really did have a positive ROI, it should be able to sustain itself as a private company, and not require federal funding.^[23] More recently, critics have faulted NASA for sinking money into theSpace Shuttle program, reducing funding available for its long-term missions to Mars and deep space.^[24]Human missions to Mars have also been denounced for their inefficiency and large cost compared to uncrewed missions.^[25] In the 2010s, Republicans in Congress increasingly opposed theEarth science aspects of NASA spending, arguing that spending on Earth science programs such as climate research was in pursuit of political agendas.^[26]
