Potential Major Reductions Proposed for NASA Science Funding in FY2026 Budget

On release of the Fiscal Year 2026 congressional budget justification, the White House proposed a substantial reduction in funding for NASA's science programs. The proposal, if enacted by Congress, would decrease the budget allocated to NASA's science division by approximately half compared to previous years. This reduction would also lead to the cancellation of several active and upcoming scientific projects managed by NASA. The affected projects have not been specified in the initial announcement. The budget justification is an early step in the U.S. federal budget process, and the final funding levels will be determined through congressional deliberations and appropriations. Historically, NASA's science programs have supported missions in planetary science, astrophysics, Earth science, and heliophysics, contributing to significant scientific discoveries and technological advancements. The proposed cuts could impact ongoing research, international collaborations, and the development of future missions. Stakeholders in the scientific community are expected to review and respond to the proposal as the budget process continues.
