The National Aeronautics and Space Administration (NASA) Science Mission Directorate (SMD) has announced the Research Opportunities in Space and Earth Sciences (ROSES) 2025: F.8 Supplemental Open Source Science Awards. This funding opportunity is part of NASA’s annual omnibus research announcement, ROSES-2025, which includes multiple program elements supporting a range of basic and applied research and technology efforts in space and Earth sciences. The solicitation was released on February 21, 2025, and proposals will be accepted continuously until the closing date of March 31, 2026.

The purpose of this grant opportunity is to provide supplemental funding for open-source science projects in alignment with NASA’s strategic goals. While the specific scope and focus of individual program elements may vary, this funding opportunity supports research efforts that contribute to the development, enhancement, and dissemination of open-source scientific software, data, and methodologies. The program seeks to promote collaboration, transparency, and reproducibility in scientific research by supporting projects that adhere to open-source principles.

The funding will be provided through grants, cooperative agreements, or contracts, with most awards being granted as research grants. The total available funding amount, award ceiling, and award floor have not been specified. The number of awards expected to be distributed has also not been disclosed. Proposals should align with NASA’s research objectives and will be subject to specific submission requirements outlined in the corresponding program element text. The typical period of performance for an award is three years, but some programs may allow for up to five years, while others may specify shorter periods.

Eligibility for this funding opportunity is generally limited to U.S.-based institutions; however, foreign organizations may be eligible under a no-exchange-of-funds policy. Proposers must be affiliated with an institution registered in NASA’s NSPIRES system. Special conditions may apply to non-U.S. organizations, including those that participate in joint programs sponsored by NASA and international agencies. Interested applicants should refer to the NASA Proposer’s Guide for detailed eligibility criteria and submission guidelines.

There is no specific deadline for proposal submission other than the final closing date of March 31, 2026. Proposals may be submitted at any time, subject to resubmission and duplicate proposal policies. The ROSES-26 version of this program is expected to overlap with the ROSES-25 version to ensure continuous submission opportunities. Applicants must retrieve the application instructions document from the provided links and ensure they submit all required forms as part of their proposal package.
