ROSES25: D.3C XRISM General Observer - Type 2
This funding opportunity provides researchers access to conduct high-resolution X-ray studies using data from the XRISM mission, promoting collaborative astrophysics research and observations.
The National Aeronautics and Space Administration (NASA), through its Science Mission Directorate (SMD), is offering funding under the ROSES omnibus solicitation for 2025, specifically under the D.3C XRISM General Observer - Type 2 program element. This opportunity falls within the Astrophysics Division and supports the broader objective of enhancing space and Earth science research through observational capabilities. XRISM (X-Ray Imaging and Spectroscopy Mission) enables high-resolution X-ray studies, and this funding opportunity provides researchers access to conduct general observer studies using XRISM data. NASA aims to promote scientific advancement through targeted research that utilizes XRISMโs unique observational platform. The Type-2 mechanism under this opportunity involves submission through the NSPIRES portal and emphasizes collaborative and joint observing opportunities with other missions such as XMM-Newton and NuSTAR. This includes provisions for coordinated or simultaneous observations when scientifically justified. Additionally, the solicitation allows for time-constrained and Target-of-Opportunity (TOO) observations, although such proposals are capped at 20% of total observing time. Applicants should consult Section 8 of the program text for detailed guidance on these specialized submissions. Although the exact amount of funding available for this program element is not specified in the synopsis, awards may be made as grants or cooperative agreements. The standard period of performance is typically three years, though some awards may vary depending on the complexity and duration of the proposed work. Cost sharing is not required, and the program encourages a broad spectrum of participants, including U.S.-based institutions and, under specific conditions, foreign organizations operating under a no-exchange-of-funds policy. Non-U.S. entities proposing to involve U.S.-based personnel for whom NASA support is requested must adhere to the NASA Grant and Cooperative Agreement Manual (GCAM). The application deadline for this opportunity is February 27, 2026, for both the Type-1 Phase-1 and Type-2 NSPIRES proposals. Proposals must be submitted via NSPIRES unless special arrangements are made at least 30 days prior to the deadline for Grants.gov submission. The final text of the program element and submission instructions can be found by navigating through Tables 2 or 3 of the ROSES 2025 solicitation page on NSPIRES, where links to the PDF documents for each element are provided. This funding opportunity is part of the broader ROSES 2025 initiative, which includes multiple program elements across various science divisions such as Earth Science, Heliophysics, and Planetary Science. Each element has specific deadlines, objectives, and eligibility rules. Questions regarding this particular funding announcement may be directed to Sanaz Vahidinia at sanaz.vahidinia@nasa.gov. General inquiries about the ROSES 2025 framework can be sent to the SMD Deputy Associate Administrator for Research via sara@nasa.gov. Researchers are also encouraged to subscribe to NASA mailing lists and blogs for ongoing updates and new program elements.

Eligible Applicants
Additional Requirements
Proposers must be affiliated with an institution at nspires.nasaprs.com/ and, in general, NASA provides funding only to U.S. institutions. Organizations outside the U.S. that propose on the basis of a policy of no-exchange-of-funds; consult the NASA Grant and Cooperative Agreement Manual (GCAM) (https://www.nasa.gov/grants-policy-and-compliance-team/#Regulations) for specific details. Some NRAs may be issued jointly with a non-U.S. organization, e.g., those concerning guest observing programs for jointly sponsored space science programs, that will contain additional special guidelines for non-U.S. participants. Also reference the GCAM for special instructions for proposals from non-U.S. organizations that involve U.S. personnel for whom NASA support is requested.
Geographic Eligibility
All
Emphasize scientific justification for joint or TOO observations; comply strictly with NSPIRES and GCAM instructions.
