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 through March 31, 2026 (the open period of ROSES-25), but reviews will occur a few times a year (see Table C.2-1 in Section 3.1).
ROSES-2025 Amendment 6 makes several changes: It establishes that the anonymized Table of Work Effort and references are outside of the 5-page S/T/M section (see Section 3.2), removes an exclusion regarding data archiving (see Section 2.1), changes the first proposal submission cut-off date for inclusion in the Winter 2025 review to September 15, 2025, changes the second estimated review date to Spring 2026 (see Table C.2-1 in Section 3.1), and removes the HEC requirement in the S/T/M as it appears as a cover page question, see Section 3.2. New text is in bold and deleted text is struck through.
On or about August 1, 2025, this Amendment to the NASA Research Announcement “Research Opportunities in Space and Earth Sciences (ROSES) 2025” (NNH25ZDA001N) will be posted on the NASA research opportunity homepage at https://solicitation.nasaprs.com/ROSES2025
