Typical award duration is 3 years; some programs allow up to 5 years. Award size varies by project scope.

Supports research teams advancing Earth system science through the Snow4Flow suborbital mission, focusing on snow and hydrological processes.

--- ## Description This funding opportunity is part of NASA's annual Research Opportunities in Space and Earth Sciences (ROSES) omnibus announcement, specifically targeting the Earth Venture Suborbital-4 (EVS-4) Snow4Flow Science Team. The program seeks proposals for research that leverages the Snow4Flow suborbital mission to advance understanding of snow processes and their role in the Earth's hydrological cycle. Projects are expected to contribute to NASA’s Earth Science Division objectives by improving scientific knowledge, data analysis, and modeling related to snow and water flow. The ROSES-2025 solicitation encompasses a wide range of basic and applied research in space and Earth sciences, with each program element (such as this one) having its own due dates and specific requirements. Awards are typically made as grants or cooperative agreements, depending on the nature of the work proposed. --- ## Due Dates - **Notice of Intent (optional):** August 12, 2025 (via NSPIRES) - **Full Proposal Deadline:** September 9, 2025 --- ## Funding Amount - **Award Duration:** Typically 3 years; some programs may allow up to 5 years. - **Award Size:** Varies based on project scope and budget justification; consult the program element text for guidance. - **Funding Instrument:** Grants and cooperative agreements (contracts are generally excluded for this element). --- ## Eligibility - **Eligible Applicants:** Institutions registered with [NSPIRES](https://nspires.nasaprs.com/).
