Can you apply?
This grant is for institutions and researchers conducting foundational astronomical sciences research. Universities, colleges, research institutes, and individual investigators with appropriate institutional affiliation may apply. Proposals must focus on core astronomy/astrophysics research, advanced instrumentation, or mid-scale innovations in space sciences. Research need not have near-term commercial outcomes but should demonstrate intellectual ambition and transformative potential.
The program prioritizes fundamental discovery over applied development. Research areas include stellar evolution, exoplanet detection, black hole physics, solar activity prediction, and cosmological studies. Investigators at all career stages can apply through their home institutions.
This is a national program with no geographic restrictions. International collaborators may be included if a U.S. institution leads the project.

Program description
The U.S. National Science Foundation Directorate for Mathematical and Physical Sciences (NSF MPS) supports multiple research programs in the astronomical sciences. NSF MPS funds foundational astronomical sciences research and instrumentation focused on exploring space and advancing fundamental understanding of the universe.
The programs covered by this funding opportunity are:
Research supported by these programs is essential for ongoing discovery in a range of fields. The programs provide a strong scientific foundation for America’s capabilities in multiple areas: predicting solar storms, discovering potentially habitable planets in other solar systems, understanding the physical workings of extreme astrophysical objects like black holes, and more.
NSF MPS is particularly interested in intellectually ambitious and potentially transformative foundational research. Proposals need not promise a near-term product, deployment, or commercial outcome, nor need they address later-stage development to be competitive.

FAQ
Who can apply for NSF MPS Astronomical Sciences funding?
Researchers at universities, research institutions, and colleges with appropriate institutional affiliation. Individual researchers must apply through their home institution.
What types of research does NSF MPS support?
Foundational astronomy and astrophysics research, instrumentation development, and mid-scale innovations. Research should be intellectually ambitious but need not have immediate commercial applications.
What is the application deadline?
November 16, 2026. This is a fixed deadline; rolling submissions are not accepted for this funding cycle.
How competitive is this program?
Very competitive. NSF receives thousands of proposals annually across all MPS programs. Strong proposals demonstrate novel scientific questions and methodological rigor.
What is the typical award range?
Award sizes vary significantly by program (core research, instrumentation, mid-scale). Check specific program solicitations for details on typical funding levels.
💡 Tips for applicants
- Align your proposal with one of the three specific programs (Core Research, Technology & Instrumentation, or Innovations). Each has distinct priorities and review criteria.
- Emphasize the intellectual merit and transformative potential of your research. NSF prioritizes fundamental discovery over near-term applications.
- Build in preliminary results or feasibility data. Reviewers want evidence your team can execute the proposed work.
- Partner with complementary expertise. Multi-institutional collaborations strengthen proposals, especially for instrumentation projects.
- Budget carefully and justify every expense. NSF reviewers scrutinize budgets closely, particularly for equipment and personnel costs.
⚠️ Common mistakes
Proposing applied research or development projects instead of fundamental science. NSF MPS prioritizes discovery over near-term products.
Submitting vague scientific objectives or unclear methodology. Reviewers need specific, testable hypotheses and sound technical approaches.
Underestimating proposal complexity or timeline. Astronomical research often requires years of careful work; overly optimistic timelines hurt credibility.
