The National Aeronautics and Space Administration (NASA) Science Mission Directorate (SMD) has released its annual Research Announcement, "Research Opportunities in Space and Earth Sciences (ROSES) – 2025," which includes the program element "D.17 XRISM General Observer Cycle 2." This funding opportunity provides support for research in space science, particularly utilizing data from the X-ray Imaging and Spectroscopy Mission (XRISM). XRISM is a collaborative effort between NASA and international partners aimed at advancing high-energy astrophysics through X-ray observations.

The primary objective of this grant opportunity is to support investigators seeking to conduct research using XRISM data. The solicitation is part of NASA’s broader ROSES-2025 omnibus announcement, which encompasses various program elements across different divisions of space and earth sciences. Awards are expected to be issued primarily as grants or cooperative agreements. Proposals should aim to contribute to the understanding of astrophysical phenomena through the application of XRISM observational capabilities.

Eligibility for this funding opportunity is generally restricted to U.S. institutions, though certain international organizations may apply under a no-exchange-of-funds policy. Proposers must be affiliated with an institution registered with the NASA Solicitation and Proposal Integrated Review and Evaluation System (NSPIRES). Specific guidance for non-U.S. applicants is detailed in the NASA Proposer’s Guide.

Applicants must retrieve the required instructions and forms from the ROSES-2025 solicitation tables available on NSPIRES. Proposals should align with the guidelines set forth in the call for proposals and must include all necessary documentation. The application period opens on February 21, 2025, with a submission deadline of May 15, 2025. No cost-sharing or matching funds are required for participation.

The typical period of performance for awarded projects is three years, though some projects may be allowed up to five years based on specific program requirements. The number of awards to be issued has not been specified, nor have the maximum or minimum award amounts. Funding is contingent on NASA’s budget allocations for the program and the merit of the submitted proposals.

For inquiries regarding this opportunity, applicants may contact Sanaz Vahidinia at the Astrophysics Division, Science Mission Directorate, NASA Headquarters. She can be reached by telephone at 202-510-1982 or via email at sanaz.vahidinia@nasa.gov. Additional details and application requirements are available through the ROSES-2025 solicitation on NSPIRES.
