The National Aeronautics and Space Administration (NASA) Science Mission Directorate (SMD) has released the Research Opportunities in Space and Earth Sciences (ROSES) – 2025 omnibus solicitation, which includes multiple program elements, one of which is the A.42 Earth Venture Suborbital-4 Snow4Flow Science Team. This funding opportunity is intended to support scientific research in Earth sciences, specifically focusing on suborbital investigations related to snow hydrology. The goal of the Snow4Flow Science Team is to improve understanding and prediction of snowpack evolution and its contribution to water resources using suborbital and remote sensing data.

Funding for this opportunity will be distributed as cooperative agreements or grants, depending on the nature of the proposed work. While specific funding amounts, including award ceilings and floors, are not provided in the synopsis, NASA anticipates making multiple awards. Cost-sharing or matching funds are not required. The period of performance for funded projects will typically be three years, though some may extend up to five years. NASA has indicated that awards will primarily be issued as grants rather than contracts.

Eligibility for this funding opportunity is limited to institutions registered with NASA’s NSPIRES system. Generally, NASA funds only U.S. institutions; however, organizations outside the U.S. may participate under a policy of no-exchange-of-funds. Some exceptions exist for specific joint research efforts with international partners. Detailed eligibility guidelines can be found in the NASA Proposer’s Guide, which provides information on policies governing non-U.S. applicants and their U.S.-based collaborators.

Applications for this opportunity require proposers to retrieve the necessary forms and instructions from NSPIRES. A key requirement is the submission of an optional Notice of Intent (NOI) by April 30, 2025. The final application deadline is June 4, 2025. Applicants must carefully review the ROSES-2025 solicitation tables for any additional requirements relevant to their program element. Proposals should align with the overarching goals of NASA’s Earth Science Division, ensuring that research contributions support NASA’s scientific mission and data collection efforts.

NASA provides multiple resources for applicants, including a list of frequently asked questions and direct contacts for program officers. Applicants are encouraged to stay informed about updates to the ROSES-2025 solicitation by subscribing to NASA’s mailing lists, blog feeds, and due date calendars. General inquiries about the ROSES-2025 announcement can be directed to the SMD Deputy Associate Administrator for Research at sara@nasa.gov.
