This opportunity supports research in solar system science as part of NASA’s annual omnibus Research Opportunities in Space and Earth Sciences (ROSES-2025) solicitation. The program seeks proposals spanning a wide range of fundamental and applied studies related to planetary systems, their origins, evolution, and current processes. Research funded under this call may include laboratory studies, theoretical modeling, data analysis, and technology development directly relevant to solar system science.
Proposals are evaluated through a dual-anonymous peer review process and must adhere to all requirements outlined in the ROSES-2025 Summary of Solicitation and the C.2 Solar System Science program element. The program encourages interdisciplinary and innovative projects that advance NASA’s planetary science objectives.
