Funder: National Science Foundation (NSF)
Due Dates: November 17, 2025 (Plasma Physics) | November 26, 2025 (AMO Theory & Experiment, Gravitational Physics, LIGO Support, Integrative Activities) | December 2, 2025 (Elementary Particle Physics Experiment, Particle Astrophysics Experiment) | December 9, 2025 (Nuclear Physics, Elementary Particle Physics Theory, Particle Astrophysics and Cosmology Theory, Physics of Living Systems, Quantum Information Science)
Funding Amounts: Approximately $120 million total annually; about 300 awards expected each year; award size and duration vary by project type.
Summary: Supports investigator-initiated physics research across a broad range of subfields, encouraging diversity, collaboration, and innovative mid-scale infrastructure and long-duration projects.
Key Information: Proposals must be submitted by U.S.-based institutions or organizations; multiple proposal submissions encouraged to be coordinated with program officers; mid-scale infrastructure awards ($4M-$30M) and long-duration efforts have special review and management requirements.
