ROSES 2025: D.4 Theoretical and Computational Astrophysics Networks

ROSES: D.4 Theoretical and Computational Astrophysics Networks is a federal research funding opportunity administered by the National Aeronautics and Space Administration through NASA Headquarters and the Science Mission Directorate. It is an individual program element within NASA's omnibus Research Opportunities in Space and Earth Sciences solicitation. The broader ROSES solicitation supports a wide range of basic and applied research and technology activities across NASA science disciplines. The Assistance Listing is 43.001, Science, and the funding activity category is Science and Technology and other Research and Development. Awards under ROSES may generally take the form of grants, cooperative agreements, or contracts depending on the nature of the proposed work, although most extramural research awards are grants. This specific opportunity identifies grants and cooperative agreements as funding instrument types. This program element concerns Theoretical and Computational Astrophysics Networks. NASA released the final text for this program element through an amendment dated August 31, 2026. The program had previously been listed as TBD. NASA specifically warns prospective applicants that there are several major changes from the prior 2022 opportunity and instructs proposers to read the final program text carefully. The program will use an enhanced dual-anonymous peer review process. Proposers are directed to Section 5 and the associated Guidelines for Proposers to ROSES DAPR Programs document for information concerning this review approach. No estimated total program funding, award ceiling, award floor, or expected number of awards is stated in the provided Grants.gov synopsis. The opportunity does not require cost sharing or matching. The general ROSES information states that the typical period of performance for an award is three years, although some ROSES programs may permit periods of up to five years and others may specify shorter periods. Because this statement applies generally to ROSES rather than specifically establishing the period for this program element, applicants should consult the final program element text for the controlling requirements, funding limits, allowable costs, restrictions, and specific period of performance. Proposers must be affiliated with an institution registered at NSPIRES. In general, NASA provides funding only to U.S. institutions. The broader ROSES framework generally permits organizations of many types, including government and private organizations, for-profit and nonprofit organizations, subject to the requirements of individual program elements. Organizations outside the United States may propose on a no-exchange-of-funds basis. NASA directs non-U.S. organizations to the NASA Grant and Cooperative Agreement Manual for applicable requirements. Special instructions also apply when proposals from non-U.S. organizations involve U.S. personnel for whom NASA support is requested. Some jointly issued research announcements may contain additional guidelines for non-U.S. participants. A mandatory Notice of Intent is required for this program. Notices of Intent must be submitted through NSPIRES by October 15, 2026. Full proposals are due December 3, 2026. The Grants.gov record was posted and amended with the final program text on August 31, 2026, and lists December 3, 2026 as both the original and current closing date. The archive date is January 2, 2027. The synopsis explains that most ROSES program elements are configured for Grants.gov application only when such submission is requested at least 30 days before the due date. Applicants should use the individual NSPIRES program element page and the final program element PDF for the complete proposal requirements and submission instructions. The program will evaluate proposals through enhanced dual-anonymous peer review. Applicants should therefore follow the program's Section 5 requirements and the Guidelines for Proposers to ROSES DAPR Programs. The provided synopsis does not enumerate the complete application questions, required proposal attachments, scoring criteria, award notification date, or a specific award start date. NASA advises applicants to review the final program element document because of the major changes from the 2022 opportunity. General ROSES frequently asked questions and program officer information are also available through NASA's Science Mission Directorate research resources. The named grantor contact is Sanaz Vahidinia of the Astrophysics Division, Science Mission Directorate, NASA Headquarters, Washington, DC. The telephone number is 202-510-1982 and the email address is Sanaz.Vahidinia@nasa.gov. General questions concerning ROSES may also be directed to sara@nasa.gov. The mandatory Notice of Intent deadline is October 15, 2026, followed by the full proposal deadline of December 3, 2026. Although ROSES is described as NASA's annual omnibus Research Announcement, the source does not establish that this particular Theoretical and Computational Astrophysics Networks program element recurs annually; indeed, it identifies the prior opportunity as occurring in 2022. Therefore, this specific program element is not treated as recurring without additional evidence.

Read the final program element carefully because NASA states there are several major changes from the prior 2022 opportunity. Follow Section 5 and the Guidelines for Proposers to ROSES DAPR Programs to comply with enhanced dual-anonymous peer review requirements.
