Humanity has always been obsessed with looking up. From Copernicus proving the Earth revolves around the sun to Newton mapping gravity, we can’t help but stare into the cosmos. That fascination is on full display this month with the August 12 total solar eclipse sweeping across Greenland, Iceland, and Europe, alongside the annual Perseid meteor shower. Both events are tracked closely by NASA — America’s publicly funded civil space agency. But as you gaze up at the night sky, you could be wondering what’s falling out of your wallet. As it turns out, tax dollars fund NASA, yet nowhere near as much as you might think. So grab your eclipse glasses, snag a calculator, and let’s break down what it actually costs to reach for the stars. This is how much we pay NASAIf you’d guess NASA is eating up a big chunk of your annual tax bill, you’re in good company.When Business Insider polled over 1,000 U.S. adults, the average American estimated that NASA gets roughly 6.4% of the entire federal budget. The reality? In 2026, NASA receives about 0.36% of federal spending. That translates to roughly a third of a cent for every dollar Uncle Sam spends.Put another way: if your household pays $10,000 in annual federal income taxes, your contribution to NASA might be about $36 a year. That’s less than the price of a dinner out — or a few months of your favorite streaming service.And while that bill may be surprisingly modest, the return could be substantial. According to an economic impact report commissioned by the agency, NASA estimates that its operations generate between $2.50 and $3.00 in broader economic output for every federal dollar spent — totaling over $75.6 billion in nationwide economic activity.Though some economists debate how those math models are calculated, the agency estimates its funding supports more than 304,000 American jobs.Here’s the disconnect(Image credit: Getty Images)Why are we so convinced NASA’s budget is bigger than it actually is? Part of the answer lies in human psychology and how we process information.It’s everywhere on our screens. From surreal snapshots by the James Webb Space Telescope to high-stakes rocket launches broadcast around the globe, NASA has a massive media presence. And because the agency’s sci-fi-sounding missions (like putting humans back on the moon) are so highly publicized, our brains naturally assume its funding must be equally astronomical. This mental shortcut is known as the “availability heuristic.” Our minds also struggle with mega-numbers. We simply aren’t wired to visualize the chasms between a million, a billion, and a trillion. Once a figure hits nine or twelve zeroes, our brains blur them together into an abstract category of “huge.” Scientists dub this phenomenon “magnitude neglect.” Since we lack an intuitive sense of scale for federal spending, we unconsciously overestimate what it takes to pull off deep-space exploration, assuming it must consume a far larger chunk of the U.S. budget than it actually does.Fun fact: even at the height of the Apollo program in 1966 — when NASA was racing to land humans on the moon — its proportional share of federal spending peaked at roughly 4.4%. That budget size has never been reached since.What your tax dollars fund at NASADespite operating on 0.36% of federal funding, here is how NASA’s $24.8 billion budget from last year broke down across its primary mission areas (with a few real-world examples from each bucket):According to The Planetary Society, STEM Outreach & Education, which is not pictured, is less than 1% of NASA’s annual funding.

Government watchdogs, like the Government Accountability Office (GAO), often point out that some major space projects — like NASA’s new Artemis moon rocket — frequently run billions of dollars over budget and take longer than planned to finish.Stop Overpaying Your Taxes.

NASA budget compared to Medicare, Social Security, and moreTo put financials in perspective, NASA typically receives around 0.36% of total federal funding. Meanwhile, major mandatory spending categories get a much bigger piece of the pie:Social Security benefits generally account for about 22%,Yearly Medicare expenditures may be roughly 13.5%, andAnnual Medicaid spending is around 10%.Here’s a breakdown showing just how dwarfed space spending really is compared to these and other federal budget buckets:(Image credit: Image courtesy of The Planetary Society, used under CC BY 3.0. The image was resized to fit the page.)Would Americans pay more for space exploration?When it comes to space funding, public opinion is a mixed bag.On one hand, a recent YouGov poll found that 48% of Americans believe space missions are a “good use” of taxpayer money, compared to 30% who disagree. Interestingly, it’s one of the few issues that bridges political lines — with 54% of surveyed self-identified liberals and 57% of surveyed conservatives agreeing that the returns generally justify the price tag.That said, most people might not be eager to write a bigger check to NASA. Polling from nonpartisan analysis group Good Authority noted that while 51% of taxpayers favor keeping current spending steady, only about 20% think federal funding for space exploration is “too little.”But even if taxpayers aren’t clamoring to open their wallets, they’re definitely tuning in.An overwhelming 90% of Americans in the YouGov survey had heard about the upcoming Artemis II lunar flight. This outpaced public awareness of the Trump administration’s budget and mainstream healthcare news covering GLP-1 weight-loss drugs (semaglutide). Bottom lineWhile NASA carries enormous public visibility, its impact on the individual taxpayer’s annual bill remains relatively small.Beyond space exploration, federal investments in the agency also yield practical technological commercialization. Everyday tools we rely on, including LASIK eye surgery techniques, thermal insulation, and scratch-resistant lenses, all benefited from early NASA research (even if private companies built the final products).So as you watch the skies this August, remember what you pay for outer-space discoveries — and you can decide whether it’s worth it.
