Proposed science cuts coming into focus
The Trump administration has begun elaborating on its proposed budget for fiscal year 2026, publishing some agency-specific documents and a government-wide summary last Friday that expand on the “skinny budget” released in early May.
The National Science Foundation’s full budget request to Congress details how the proposed 57% topline cut would be distributed across the agency’s research programs and facilities. For instance, NSF proposes to operate only one of the two existing Laser Interferometer Gravitational-Wave Observatory (LIGO) sites and to cut support for the Large Hadron Collider to about 60% of the current level, reducing U.S. researchers’ participation in LHC research accordingly. NSF also indicates it will not advance the Thirty Meter Telescope project to the final design phase or supply any further funding. The agency does pledge to advance the Giant Magellan Telescope to the final design phase but does not commit to seek construction funding for the project. (The agency has been debating whether to support either project to completion.)
Despite suggested cuts to high-profile science facilities, the administration does propose to increase NSF’s major facility construction budget to $251 million, up from $234 million in fiscal year 2024. The lion’s share of this budget ($201 million) would go to the planned Leadership-Class Computing Facility led by the University of Texas at Austin.
AI and quantum information science are the only crosscutting research areas that are protected from major cuts in the budget proposal. NSF estimates the total number of competitive grant awards would plummet from around 9,600 to 2,300, and the proposal acceptance rate would drop from 26% to 7%.
NASA’s request proposes a 47% cut to science programs compared to fiscal year 2024 operating plan levels, including a 71% cut to biological and physical sciences and a 66% cut to astrophysics. The budget provides for a “leaner, more focused science program, eliminating over 40 lower-priority missions,” the document states. Among the proposed cancellations are the Mars Sample Return mission, Chandra X-ray telescope, various Earth observation satellites, and the HelioSwarm solar observation satellites. The administration also proposes to eliminate the STEM Engagement directorate.
Presidential budgets have historically served more as an indication of policy priorities than an exact blueprint for spending decisions, and Congress will advance its own spending proposals this summer. Any final discretionary spending legislation will need bipartisan support in the Senate to overcome the 60-vote threshold needed to advance bills in that chamber.
DOE begins terminating major clean energy projects
The Department of Energy terminated over $3.7 billion in clean energy grants last week that were awarded during the Biden administration. DOE did not release a list of the affected projects but said they primarily work on decarbonization or carbon capture and sequestration. The agency’s press release emphasized that 16 of the 24 awards were approved between Donald Trump’s election and his inauguration. DOE said the projects “failed to advance the energy needs of the American people, were not economically viable, and would not generate a positive return on investment of taxpayer dollars.” The terminations resulted from a DOE review of 179 awards that were “rushed out the door, particularly in the final days of the Biden administration,” Energy Secretary Chris Wright said earlier in May. At an appropriations hearing for DOE, Wright said the Biden administration awarded $93 billion in the period after Trump’s election. Democratic appropriators have sharply criticized the decision to terminate projects already selected for funding.
State Department forges ahead with plans to dissolve science offices
A major reorganization of the State Department that would eliminate multiple science offices is moving forward, with Secretary of State Marco Rubio submitting a plan to Congress last week. Internal documents reviewed by FYI suggest affected units include the Office of Science and Technology Cooperation, the Office of Global Change, the Office of the Science and Technology Advisor to the Secretary, and the Office of the Special Envoy for Critical and Emerging Technology. Statutory functions of these units will be reassigned to other offices. Current and former State Department staff warned FYI last month that disruption to the work of the Office of Science and Technology Cooperation could have a significant negative impact on scientists, as the office oversees major scientific international collaboration agreements for research facilities such as CERN and ITER, among other functions.
The organizational chart proposed by Rubio retains the position of assistant secretary of oceans, environmental, and international scientific affairs. The chart also includes a new assistant secretary for “emerging threats.”
McNutt to deliver second ‘State of the Science’ speech
National Academy of Sciences President Maria McNutt will deliver the second annual State of the Science address on Tuesday. The address aims to evaluate the state of the U.S. research enterprise and strategies for adapting to a rapidly changing scientific community. A panel discussion following the speech will be moderated by Kelvin Droegemeier, director of the White House Office of Science and Technology Policy during the first Trump administration. McNutt used last year’s address to argue the U.S. should respond to rising global competition in science and research by ensuring the country remains an attractive destination for foreign scientists and by increasing support for domestic STEM education.

Interested in Science History?
AIP has launched two email newsletters focused on the history of the physical sciences. A weekly edition features an article focusing on history and the work of the history community. For instance, the May 16 edition, “Oppenheimer–Condon–Peters: Conscience, coercion, and the Red Scare,” focused on tensions within the physics community during the anti-communist fervor of the post-World War II era. A monthly email provides updates on the work of AIP’s history research program and the AIP Niels Bohr Library and Archives. You can sign up for the emails here.
