The Trump administration's push against what it labels "woke" science is increasingly being felt in one of America's proudest scientific domains: space research. Through budget proposals, new rules on grants and the cancellation of diversity-related programmes, the effort is redrawing how federal money for science is spent, and stirring alarm among researchers.

The administration has framed its approach in stark terms, arguing that agencies should concentrate on ambitious goals rather than, in its words, subsidising "woke STEM programming". In practice, that has meant moves to end diversity, equity and inclusion activities across federal science, and proposals to slim down programmes the government deems peripheral to core missions.

What is changing

At NASA, the administration's budget request sought deep cuts, including a large reduction to the agency's science programmes and the elimination of its education and outreach office. Grants aimed at drawing students and members of under-represented groups into science, and at supporting early-career researchers, have been curtailed or cancelled. Proposed changes to how research grants are awarded would also give political appointees a greater say in decisions that have traditionally rested with scientific experts.

Supporters of the changes argue that public money should go to flagship missions and demonstrable results, not to programmes they view as ideological or duplicative. In this telling, tightening the focus of agencies like NASA is a matter of discipline and priorities, and a correction of what they see as mission drift.

The scientists' alarm

Researchers and scientific organisations see it very differently. Groups such as the Planetary Society and the American Association for the Advancement of Science have warned that the cuts and restrictions would harm US science, damaging the pipeline of young and under-represented researchers, weakening outreach that inspires the next generation, and, in the case of proposed budget reductions, threatening specific missions and America's standing as a leader in space and research.

Critics also object to the underlying framing, arguing that labelling efforts to broaden participation in science as "woke" mischaracterises programmes designed to widen the pool of talent and strengthen the field. Diversity and outreach initiatives, they contend, are not a distraction from good science but a means of sustaining it.

A contested outcome

The picture is not one of uniform retreat. Congress, which controls the purse strings, has pushed back on the deepest proposed cuts to NASA, restoring funding that the administration had sought to remove and signalling continued support for the agency's science and education work. The steepest reductions floated in budget requests have not simply been enacted; they have become the opening position in a tug-of-war between the executive branch and lawmakers.

Even so, the direction set from the top has had real effects, in cancelled grants, halted programmes and a chilling uncertainty for researchers who depend on federal support. Scientists describe a climate in which long-standing assumptions about how science is funded and evaluated can no longer be taken for granted.

The dispute is, at heart, about more than any single programme. It reflects a deeper argument over what public science is for, who it should include, and who gets to decide, an argument now playing out in the funding of the telescopes, probes and research that shape humanity's understanding of the universe. How it is resolved will influence not only budgets, but the character of American science for years to come.
