Amendment 60: Final 2025 Due Date Extended for C.2 Solar System Science
C.2 Solar System Science solicits proposals for research, data analysis, data preservation, and tools that support investigations to help ascertain the content, origin, and evolution of the Solar System and the search for life’s origin, evolution, distribution, and future in the universe. The Planetary Science Division is committed to supporting the most meritorious research, data analysis, data preservation, and tools development, and encourages efforts that involve emerging fields, systems science, and convergence research that works across disciplines to solve compelling scientific problems. Proposals may be submitted at any time, but reviews will occur a few times a year (see Table C.2-1 in Section 3.1).
Anonymized technical proposals may be submitted at any time, but reviews will occur a few times a year (see Table C.2-1 in Section 3.1). ROSES-2025 Amendment 60 adds a new row to Table C.2-1 in Section 3.1 with a new final cutoff date of November 12, 2026.
Those planning to submit to this November due date should be aware of two upcoming changes:
Potential proposers are reminded in Section 3.1 that for any proposal for federal assistance submitted > August 5, 2026, PIs and any Co-Is that would spend > 10% time on a proposed grants or cooperative agreements must certify they have taken research security training. NASA will be satisfied with the four online research security training modules on the National Science Foundation’s (NSF) Research Security Training website at https://www.nsf.gov/research-security/training or the SECURE Center condensed version of the four modules at https://www.secure-center.org/ctm
The Summary of Requirements for Expertise and Resources Not Anonymized Document in Section 3.5 was updated to indicate that biographical sketches and current and pending support documents submitted after September 1, 2026 must use the NASA-specific Science Experts Network Curriculum Vitae (SciENcv) format found at https://www.ncbi.nlm.nih.gov/sciencv/, per Grant Notice 26-01.
Questions concerning C.2 Solar System Science may be directed to Katharine Robinson, Rebekah Dawson-Rigas, and Curtis Williams at hq-scubed@mail.nasa.gov.
