The National Aeronautics and Space Administration (NASA) Science Mission Directorate (SMD) has released its annual omnibus Research Announcement, Research Opportunities in Space and Earth Sciences (ROSES) – 2025. The ROSES-2025 solicitation includes a variety of program elements, each with distinct topics and due dates, covering a broad range of fundamental and applied research in space and Earth sciences. The funding opportunity titled "F.14 High Priority Open-Source Science" under ROSES-2025 supports research in open-source science, encouraging transparency, reproducibility, and collaboration in scientific research.

Funding for this opportunity will be provided in the form of grants and cooperative agreements. Awards are expected to primarily support extramural research projects, though intra- and inter-agency transfers will also be used for government-affiliated researchers. The funding period for most awards will be three years, with some exceptions allowing up to five years or shorter durations, depending on the specific program element.

Eligible applicants for this opportunity include institutions that are listed in the NASA Solicitation and Proposal Integrated Review and Evaluation System (NSPIRES). In general, NASA provides funding only to U.S.-based institutions. However, international organizations may apply under a policy of no-exchange-of-funds agreements. Specific program elements may include collaborative efforts with non-U.S. institutions for certain research topics, particularly in space science. Applicants are advised to refer to the NASA Proposer’s Guide for details on eligibility and submission requirements.

The solicitation does not impose a specific deadline for proposal submission; proposals may be submitted on a rolling basis until the final deadline of March 31, 2026. However, applicants should be aware of potential eligibility timing restrictions, such as those related to resubmissions and duplicate proposal avoidance. The program will transition into the ROSES-2026 solicitation, which will overlap for a brief period, allowing continuous submissions across funding cycles.

Applicants must download the required instructions document from NSPIRES, as at least one mandatory form must be attached to the submission. Further details on proposal submission, evaluation criteria, and requirements are available in the full text of the solicitation, accessible via NASA’s NSPIRES website. To stay updated on changes or amendments to this funding opportunity, proposers can subscribe to the SMD mailing lists, ROSES-2025 blog feeds, and due date Google calendars.
