Estimated total program funding: $50,000,000 annually; about 100 projects funded per year.

Supports individual and collaborative research projects in astronomy and astrophysics, including observational, theoretical, laboratory, and data studies.

--- ## Description The Astronomy and Astrophysics Research Grants (AAG) Program from the U.S. National Science Foundation (NSF) is a flexible funding opportunity designed to support a broad range of research in the astronomical sciences. Funding is available for individual investigators and collaborative teams conducting observational, theoretical, laboratory, or archival data studies in astronomy and astrophysics. The program also considers proposals for projects and tools that enable or enhance astronomical research and welcomes interdisciplinary approaches that may span multiple techniques or areas of study, provided the astronomical context is clearly demonstrated. Proposals may include, but are not limited to: - Observational campaigns - Theoretical modeling - Laboratory astrophysics - Development of research tools and methods - Archival data analysis The program supports research across all areas in the field, including extragalactic astronomy and cosmology, galactic astronomy, planetary and solar astronomy, and stellar astronomy and astrophysics. --- ## Due Dates - November 15, 2022 - November 15, 2023 - November 15, 2024 - November 15, 2025 - November 16, 2026 The submission window is annually from October 1 to November 15 (with the next cycle's deadline projected as November 16, 2026, due to the calendar). Proposals are due by 5:00 p.m. local time on the closing date. --- ## Funding Amount - Estimated total program funding: $50,000,000 annually (subject to availability of funds) - Approximately 100 projects funded per year - Award type: Standard Grant or Continuing Grant There is no specified minimum or maximum award size; funding amount and duration are determined based on project needs and available funds. --- ## Eligibility - Eligible applicants: Unrestricted (open to all types of entities, including higher education institutions, nonprofits, for-profits, and government organizations, except unaffiliated individuals) - No restrictions on who may serve as Principal Investigator (PI) or co-PI - No limit on the number of proposals per organization or per PI/co-PI Proposals must be submitted by eligible organizations, not unaffiliated individuals. --- ## Application Process - Proposals may be submitted via [Research.gov](https://www.research.gov/) or [Grants.gov](https://www.grants.gov/). - Follow the [NSF Proposal & Award Policies & Procedures Guide (PAPPG)](https://www.nsf.gov/policies/pappg) for preparation and submission. - Letters of Intent and preliminary proposals are not required. - Collaborative proposals (separate submissions from multiple organizations) must be submitted via Research.gov. - Cost sharing is not required and voluntary committed cost sharing is prohibited. - Indirect cost limitations do not apply. For detailed instructions, consult the [program solicitation](https://www.nsf.gov/funding/opportunities/aag-astronomy-astrophysics-research-grants/nsf22-624/solicitation). --- ## Additional Information - Proposals should clearly state the astronomical context of the work. - Projects primarily using NASA data or resources are generally expected to apply to NASA, but exceptions are allowed with justification. - The program accepts Research in Undergraduate Institutions (RUI) and Computational and Data-Enabled Science and Engineering (CDS&E) proposals, provided they meet AAG requirements. - Supplemental funding requests (e.g., for REU or RET) can be included as part of a new/renewal proposal or requested for existing awards. --- ## External Links - [NSF AAG Program Page](https://www.nsf.gov/funding/opportunities/aag-astronomy-astrophysics-research-grants/nsf22-624/solicitation) - [NSF Publication 22-624](http://www.nsf.gov/publications/pub_summ.jsp?ods_key=nsf22624) - [Grants.gov Listing](https://www.grants.gov/search-results-detail/342959) - [NSF Proposal & Award Policies & Procedures Guide (PAPPG)](https://www.nsf.gov/policies/pappg/24-1) --- ## Contact Information | Name/Role | Email | Phone | |--------------------------|------------------------------|----------------| | NSF Grants.gov Support | grantsgovsupport@nsf.gov | - | | Hans A.
