National Science Foundation (NSF)

The NSF funds research that is often too early-stage, uncertain, or foundational for private companies to have financial incentive to support. Many NSF-backed projects do not produce immediate commercial products, but rather support general scientific knowledge, a trained workforce, research tools, and technical infrastructure that later supports advances in industry, medicine, national security, communications, energy, and education. ²

The NSF has become politically important because its work affects science, federal spending, universities, technology, and national priorities. Its grant decisions affect universities, researchers, state economies, and emerging fields, such as artificial intelligence, quantum information science, cybersecurity, climate research, and advanced manufacturing. Supporters view the NSF as a key tool for maintaining U.S. scientific leadership and economic competitiveness, while critics question whether some grants reflect political priorities, weak oversight, or spending outside the agency’s core mission. As a result, debates over NSF funding often reflect broader disputes about the role of the federal government in science, education, innovation, and public policy. ^{1  2  3}

Background

The National Science Foundation is an independent federal agency established in 1950 by the U.S. Congress to support basic science and engineering in the United States, primarily through its grant program. ¹ Its focus is to “promote the progress of science; to advance the national health, prosperity and welfare; and to secure the national defense.” ⁴ It typically distributes about $9 billion each year in grants. ⁵

The National Science Board (NSB) was established as part of the National Science Foundation Act of 1950. The NSB manages the policies and priorities of the NSF, approves major NSF grants, and serves as an independent advisory group to the U.S. Congress and the President on scientific issues. ⁶

The NSF provides grants to science and engineering researchers outside the medical sciences. It supports partnerships, primarily between universities and other organizations, to encourage research collaboration. It invests in research facilities and infrastructure such as observatories, research labs, supercomputers, and ocean vessels. It invests in improvements in educational opportunities from pre-school to graduate education and workforce development. ⁷

Several other federal agencies support research in specialized areas. The National Institutes of Health (NIH) is the world’s largest funder of biomedical research; the National Aeronautics and Space Administration (NASA) supports space and aeronautics research; the U.S. Department of Energy funds energy, national security, and physical sciences research; the National Oceanic and Atmospheric Administration (NOAA) focuses on oceans, weather, and climate; and the Defense Advanced Research Projects Agency (DARPA) within the U.S. Department of Defense supports defense-related technology research. ⁸

In an average year, the NSF supports approximately 350,000 individual researchers, students, teachers, and entrepreneurs; 1,900 colleges, universities, and research institutions; and funds approximately 11,000 competitive research, education, and training awards in the areas of science and engineering. ¹ According to its annual report, the NSF reviewed 187,829 proposals in fiscal year 2024 and distributed 11,000 awards. ⁹

History and Timeline

In May 1950, the U.S. Congress created the National Science Foundation in legislation signed into law by President Harry S. Truman to support basic research across scientific disciplines. The first NSF research grants were awarded in February 1952. After the Soviet Union launched Sputnik in 1957, federal support for science and engineering expanded significantly, and the NSF was expanded. It supported major advances in astronomy, geosciences, and oceanography. It funded programs and facilities that contributed to discoveries such as the structure and patterns of the atmosphere and the development of radio and optical observatories. It was instrumental in opening Antarctica to scientific research. ¹⁰

In the 1960s, the NSF increased investments in university research laboratories and scientific equipment. In the 1970s, the NSF expanded into applied research, environmental studies, and interdisciplinary work. In the 1980s, the NSF became closely associated with high-performance computing, launching its supercomputer centers program and developing networking technologies that evolved into the early internet. In the 1990s and 2000s, the NSF funded work in nanotechnology, materials science, biotechnology, environmental science, and climate research. It partnered with IBM and Google in support of the development of cloud computing. From the 2010s onward, the NSF continued to expand its focus areas to include artificial intelligence, quantum engineering, advanced manufacturing, biological sciences, cybersecurity, and STEM. ^{10  11  12}

NSF-Funded Achievements

According to the National Science Foundation’s impacts page, the agency’s long-term investments have affected modern science, technology, and everyday life. The NSF identifies areas such as critical and emerging technologies, new scientific frontiers, national security, health, STEM workforce development, and the broader U.S. research ecosystem. The page emphasizes that NSF-supported research has contributed to technologies and tools people use regularly, including cell phones, weather reports, web search, and the MRI. ¹³ Several major technology areas were advanced through NSF support, including the internet, 3-D printing, fusion energy research, semiconductors, quantum technology, lasers, artificial intelligence, and supercomputers. ¹³

The NSF played a widely recognized role in early internet development. Its NSFNET was launched in 1986 to connect academic researchers with NSF-supported supercomputer centers. It became the backbone of the U.S. internet and expanded from approximately 2,000 connected computers in 1986 to more than 2 million by 1993. The NSF describes NSFNET as laying the foundation for the commercial internet’s rapid growth in the 1990s. ¹⁴

The NSF supported research in nuclear magnetic resonance, electromagnetics, biophysics, biochemistry, and computer engineering beginning in the 1950s that laid the groundwork for developing the MRI scan. More recent funding has supported improvements in MRI technology. ¹⁵

In 2000, the NSF published a “Nifty 50” list of NSF-funded projects that are commonplace today. These included common concepts such as bar codes, computer-aided design and computer-aided manufacturing, data compression technology, Doppler radar, fiber optics, nanotechnology, and speech recognition technology. In 2010, it published the “Sensational 60” list, which included new concepts such as cloud computing, deep-sea drilling, and supercomputer facilities. For its 70th year in existence, the NSF commissioned a mural located at its headquarters that visualizes its history of achievements. Newly added items included robotics and automation in transportation and virtual reality technologies. ¹⁶

Focus Areas

The National Science Foundation identifies 17 focus areas in the fields of science and engineering that it supports; these areas include the Arctic and Antarctic, astronomy and space, biology, chemistry, computing, STEM workforce, the earth and environment, education and training, engineering, facilities and infrastructure, materials research, mathematics, people and society, physics, research partnerships, technology, and interdisciplinary, convergence, and transformative research. ¹⁷

In May 2026, the NSF launched the X-Labs initiative, a 10-year, $1.5 billion program to “accelerate breakthrough science. It funds independent research teams working outside traditional universities and companies. The program focuses on key challenges like new scientific tools and quantum technology. It is designed to give teams more flexibility, long-term funding, and the ability to turn early ideas into real-world technologies by enabling new research and development approaches with interdisciplinary teams of researchers, engineers, and entrepreneurs. The effort was designed to revitalize U.S. scientific leadership and back a “new generation of independent research organizations” to address scientific challenges that are “difficult to pursue in conventional academic and industry labs.” ^{18  19}

Research Facilities

The National Science Foundation funds, builds, and oversees major scientific facilities in partnership with other organizations. For instance, LIGO, or the Laser Interferometer Gravitational-Wave Observatory, is supported by the NSF and operated by the Massachusetts Institute of Technology and the California Institute of Technology. ²⁰

The Vera C. Rubin Observatory, which uses the largest digital camera ever built, is a joint project of the NSF and the U.S. Department of Energy and is managed by the Association of Universities for Research in Astronomy. ²¹

The U.S. Antarctic Program is the NSF’s largest and most complex program. It includes the McMurdo, South Pole, and Palmer year-round research stations and a research vessel. The NSF collaborates with other federal agencies, the military, and civilian contractors for ongoing operations and support. ²² These include the U.S. Air Force, the U.S. Navy, the EarthScope Consortium, NASA, NOAA, the University of Wisconsin, and the University of Minnesota. ²³

Frontera is the fastest academic supercomputer in the United States and the fastest supercomputer on a university campus. The NSF was funded by a $60 million grant to the Texas Advanced Computing Center at the University of Texas. ²⁴

The National Ecological Observatory Network (NEON) is the only nationwide ecological observatory network of its kind. It has 81 field sites that collect long-term ecological and climate data, funded by the NSF and operated by Battelle. ²⁵

Organization

As an independent federal agency, the National Science Foundation is directly accountable to the President and the U.S. Congress. ¹²

The NSF is led by a central office of the director, which includes the NSF director and deputy director, along with senior officials such as the chief of staff, chief science officer, and chief management officer. The office of the director oversees the agency’s mission, sets priorities, and coordinates policy across the foundation. It is supported by specialized offices covering civil rights, general counsel, legislative and public affairs, research security, financial management, human resources, information technology, and award administration. ²⁶

The NSF carries out its scientific work through directorates organized around broad research areas, including biological sciences, engineering, computer and information science, geosciences, mathematical and physical sciences, STEM education, and technology and innovation partnerships. Within these directorates, program officers manage funding opportunities, organize proposal reviews, and recommend grants for approval. The NSF also includes the National Center for Science and Engineering Statistics and an independent Office of Inspector General. ²⁶

In December 2025, the NSF was reorganized to “reduce the number of layers in the organization” in an effort to be more efficient. ²⁷ The reorganization was introduced by the White House Office of Personnel Management to enforce existing rules that were previously ignored. These rules required that supervisors be federal employees with no more than 10 direct reports. Prior to this reorganization, the NSF leveraged people on loan, typically from universities, to be supervisors managing large numbers of people. By eliminating these positions, it was able to reduce the size of its staff. ²⁸

In April 2026, the second Trump administration fired the entire National Science Board due to what it called “‘constitutional questions’ raised by a 2021 Supreme Court ruling.” The ruling set limits on “the powers of executive branch officials who are not Senate-confirmed.” The NSB was a group of 24 members with scientific backgrounds from universities and private industry who were appointed by the President to establish the policies of the NSF, approve major NSF grants, and serve as advisor to the U.S. Congress and the President on scientific issues. This action was criticized by scientific organizations and left-of-center advocacy groups, including the Association of American Universities, the Association of Public and Land-Grant Universities, the American Association for the Advancement of Science, the Union of Concerned Scientists, and the National Academy of Education. ^{29  30}

Funding and Grants

In 1950, the U.S. Congress appropriated $225,000 to establish the National Science Foundation. ³¹ In fiscal year 1952, it awarded over $1 million in research grants. ³²

In 2010, the Obama administration reauthorized the America COMPETES Act, which would “double NSF funding over seven years.” By 2011, the NSF had a $6.9 billion annual budget. ¹² Since then, the annual appropriation for the NSF had increased each year until 2025. ³³

In 2025, appropriations totaled $9.06 million, which was the same level as in 2024. ³⁴ In January 2026, the U.S. Congress appropriated $8.75 billion for the NSF in the FY2026 Commerce, Justice, Science spending bill, as part of a minibus package. ³⁵

NSF grants begin with a funding opportunity announcement, solicitation, or program description that explains the research area, eligibility rules, deadlines, required proposal materials, and review criteria. Applicants submit proposals through Research.gov or Grants.gov. Proposals that meet submission requirements are assigned to the appropriate program and reviewed by NSF program officers, usually with input from outside experts through a merit review process. NSF program officers make recommendations based on this reviewer input along with available budget, program goals, and project potential. Senior NSF officials then review funding recommendations before final award or decline decisions are made. ³

In December 2025, the Office of Management and Budget of the Trump administration issued the President’s Management Agenda, which called for efforts to “eliminate waste, ensure accountability, rebuild American industry, and deliver results for the American people.” ³⁶ In the NSF’s 2026-2030 Strategic Plan, the agency committed to reducing administrative burden by streamlining its proposal and award management processes. ⁴

Leadership

In April 2025, then-National Science Foundation director Sethuraman Panchanathan resigned from his position. Panchanathan was originally nominated in 2020 by President Donald Trump. ³⁷ Panchanathan earned a master’s degree in electrical engineering from the Indian Institute of Technology in Madras, India and a Ph.D. in electrical engineering from the University of Ottawa. Before his nomination to the NSF, he was a professor at the University of Ottawa for eight years. He then joined Arizona State University (ASU), where he held several leadership roles over the course of almost 29 years. He founded its Center for Cognitive Ubiquitous Computing and its School of Computing and Informatics. In 2014, Panchanathan was appointed to the U.S. National Science Board by former President Barack Obama. After leaving the NSF in April 2025, he became a full-time ASU professor of technology and innovation. ^{38  39}

As of June 2026, the NSF director position was vacant. NSF chief of staff Brian Stone was performing the duties of the director. Stone earned a master’s degree in business administration from George Washington University in 2004. He has spent his career at the NSF, starting as a research support manager. He was a senior executive in the Antarctic directorate, coordinating with the U.S Department of Defense, the National Oceanic and Atmospheric Administration (NOAA), and the National Aeronautics and Space Administration (NASA) on operational logistics. He became the NSF chief of staff in 2016 and still holds that role as of June 2026 while performing the duties of the NSF director. ^{40  41}

In March 2026, President Donald Trump nominated Jim O’Neill to fill the role of director of the NSF. Most recently, he was the deputy secretary at the U.S. Department of Health and Human Services, then the acting director of the Centers for Disease Control and Prevention. Previously, he was the CEO of the SENS Research Foundation and of the Thiel Foundation. As of June 2026, his nomination had not been confirmed by the U.S. Senate. ^{42  43}

Controversies and Criticism

Online Censorship

In November 2022, the Foundation for Freedom Online (FFO) released findings indicating that the NSF had spent $38.8 million on government grants and contracts since the start of the Biden administration to colleges and universities in order for them to research “the science of ‘countering’ social media ‘mis/disinformation.’” Some of these grant descriptions indicate they target populist politicians and are awarded “to scientifically determine “how best to counter populist narratives.” Grantees included the State University of New York, George Washington University, the University of Wisconsin, and the University of Washington. ⁴⁴

In April 2025, the NSF terminated over $230 million in research grants associated with “diversity, equity, and inclusion (DEI) and misinformation/disinformation,” as these areas are “not aligned with NSF’s priorities.” ⁴⁵ A 2024 House Judiciary Committee report claimed that some NSF-funded projects were developing tools to “shape public opinion by restricting certain viewpoints and promoting others,” that taxpayer funding was being used to support censorship and infringe on constitutionally protected speech. ⁴⁶

Judicial Reference Manual

In February 2026, 24 state attorneys general were pressuring federal agencies and the U.S. Congress to investigate the National Science Foundation and the National Academy of Sciences (NAS) for their roles in producing a climate science chapter included in a judicial reference manual. The AGs argued that the NSF and NAS helped create a “politically biased climate chapter” that violated the agencies’ own commitments to scientific objectivity and their statutory duties in a way that could affect judicial impartiality. They claimed that the organizations refused to correct or retract the chapter even after concerns were raised, and they urged Congress to halt the funding of both groups until an investigation is completed. ⁴⁷

Coburn Report

In April 2011, then-U.S. Sen. Tom Coburn (R-OK) published a report entitled The National Science Foundation: Under the Microscope which provided a comprehensive overview of the National Science Foundation. The report indicated that, although the NSF has “contributed significantly to scientific discovery,” it has mismanaged funds, spent on duplicate efforts performed by other government agencies, and funded questionable projects. Examples of fund mismanagement include $1.7 billion in expired grant accounts that were not returned to the U.S. Treasury, a lack of oversight and audits of NSF-supported projects to ascertain where the funds were actually used, and millions of dollars in NSF funds used for conferences and expensive employee travel. It referenced activities such as jello-wrestling, porn-surfing, and skinny-dipping at the McMurdo Antarctic research station and extended taxpayer-funded trips for romantic liaisons with women in other countries. The report listed NSF-funded projects that have questionable value such as “Should you buy sporting tickets in advance or at the last-minute?,” “Exactly how much housework does a husband create?,” “How do you ride a bike?,” and “How long can a shrimp run on a treadmill?.” It listed some NSF funded projects that would only provide value to politicians, such as “Can Members of Congress improve their approval ratings through internet town halls?,” “Do your genes impact your political views?,” and “How can politicians motivate people to make political donations?” The report provided recommendations to better define justifications for funded projects, increase grant oversight and accountability for research outcomes, and eliminate funding for certain social science areas. ¹² Overall, the report identified $19 million in fraud, $1.2 billion in duplicative spending, $1.9 billion in spending as a result of mismanagement, and $65 million on questionable projects. ⁴⁸

Ocean Observatories Initiative

The National Science Foundation Ocean Observatories Initiative (OOI) is a $386 million network of more than 900 ocean-monitoring instruments that deliver open-access data on “ocean health, climate variability, and marine biodiversity” to anyone in the world. ⁴⁹ The initiative costs $40 million annually to maintain. As part of a broader effort to cut environmental and climate-related science operations, the Trump administration planned to dismantle four of the five ocean monitoring systems. The NSF had already begun removing sensors when lawmakers, scientists, and coastal communities pushed back. U.S. Sen. Jeff Merkley (D-OR) and U.S. Sen. Lisa Murkowski (R-AK) led a congressional effort to block the move, arguing that eliminating the system threatened public safety, fisheries, emergency response, and vital climate data. Other signatories of the letter included U.S. Senators Elizabeth Warren (D-MA), Edward Markey (D-MA), Ron Wyden (D-OR), and Tammy Baldwin (D-WI). After the backlash, the NSF reversed course, announced it would halt removals, and said it would work to redeploy the instruments already taken out. ^{50  51  52}
