Full Details of Deadlines
2025 Jul 10 - 2026 May 31: Upcoming ROSES-2025 Full (Step-2 or Phase-1) Proposal Deadlines
NASA's Science Mission Directorate (SMD) announces the release of its annual omnibus solicitation for basic and applied research, Research Opportunities in Space and Earth Science (ROSES) 2025 at https://solicitation.nasaprs.com/ROSES2025 on or about February 21 2025. This year, ROSES2025 was released on Jul 10, 2025. ROSES is an omnibus solicitation, with many individual program elements, each with their own due dates and topics. Tables 2 and 3 of this NRA, at http://solicitation.nasaprs.com/ROSES2025table2 and http://solicitation.nasaprs.com/ROSES2025table3, respectively, provide proposal due dates and hypertext links to descriptions of the solicited program elements in the Appendices of this NRA. Together, these program elements cover the wide range of basic and applied research and supporting technology in areas supported by SMD.
The ROSES NRA is written to allow program elements to issue awards to non-governmental organizations as grants, cooperative agreements, or contracts depending on the nature of the work proposed. However, at the time of release, all active program elements of ROSES specifically exclude contracts, because contracts would not be appropriate for the nature of the work solicited. Thus, unless otherwise specified by the program element, awards to non-governmental organizations deriving from ROSES will be federal assistance (grants or cooperative agreements). Awards to government labs, including funded Co-Investigators on proposals non-governmental organizations, will be inter- or intra-agency transfers, as appropriate.
Altogether these program elements cover the wide range of basic and applied supporting research and technology in space and Earth sciences supported by SMD. The topics and types of proposals solicited include flight investigations, using suborbital-class platforms (including aircraft, balloons, sounding rockets, CubeSats, commercial suborbital reusable launch vehicles, and small International Space Station payloads), and all kinds of ground-based supporting research and technology investigations that seek to understand naturally occurring space and Earth phenomena, human-induced changes in the Earth system, and Earth and space science-related technologies and to support the national goals for further robotic and human exploration of space. These ground-based investigations include, but are not limited to: theory, modeling, and analysis of SMD science data, (together with data from SMD's international and/or interagency partners) development of concepts, techniques and advanced technologies suitable for future SMD space missions; development of methods for laboratory analysis of both extraterrestrial samples returned by spacecraft and terrestrial samples that support or otherwise help verify observations from missions; determination of atomic and composition parameters needed to analyze space data, as well as returned samples from the Earth or space; Earth surface observations and field campaigns that support SMD science missions; development of integrated Earth system models; development of systems for applying Earth science research data to societal needs; and development of applied information systems applicable to SMD objectives and data.
Except for China (see Section III.c of the ROSES Summary ofSolicitation), organizations of every type, domestic and foreign, government and private, for profit and not-for-profit, may submit proposals without restriction on teaming arrangements. Note that it is NASA policy that all research conducted by non-U.S. organizations will be no exchange of funds, see SARA FAQ-14.
Awards range from under $100K per year for focused, limited efforts (e.g., data analysis) to more than $1M per year for extensive activities (e.g., development of hardware for science experiments and/or flight). Periods of performance are typically three years, but some programs may allow up to five years and others specify shorter periods.
The funds available and the anticipated number of awards are given in each program element and range from less than one to several million dollars, which allows for selection from a few to as many as several dozen proposals. Continued solicitation of proposals and issuance awards is contingent on appropriation of funding.
Electronic submission of proposals is required by the respective due dates for each program element and must be submitted by an authorized official of the proposing organization. Most program elements will be set up for application via Grants.gov only if requested at least 30 days in advance of the due date. For more on Grants.gov submissions see Section IV(b)v of the ROSES Summary of Solicitation, that may be found at the ROSES 2025 site.
Every organization that intends to submit a proposal in response to ROSES must be registered with NSPIRES; organizations that intend to submit proposals via Grants.gov must be registered with Grants.gov in addition to being registered with NSPIRES. Such registration must identify the authorized organizational representative(s) who will submit the electronic proposal. All proposal team members must be registered in NSPIRES regardless of the submission system so we may perform automatic organizational conflict of interest checking of reviewers. Potential proposers and proposing organizations are urged to access the system(s) well in advance of the proposal due date(s) of interest to familiarize themselves with its structure and to enter the requested information.
Notices of intent to propose and Step-1 Proposals will be due no earlier than August 11, 2025, and full (Step-2) Proposals will be due no earlier than September 9, and may be due as late as May 2026, at which time it is expected that the first full (Step-2) proposal due dates for ROSES-26 will begin.
Potential proposers are strongly encouraged to read Section I(d) of the ROSES Summary of Solicitation and ROSES-25 FAQ#1 that list significant changes from recent ROSES.
Compliant and responsive proposals are peer reviewed vs. the standard evaluation criteria defined in Section 12 of the NASA Grants and Cooperative Agreement Manual (GCAM) available on the Grants Policy web page here.
To learn of the addition of new program elements and all amendments to this NRA, proposers may subscribe to:
- The SMD mailing lists (by logging in at http://nspires.nasaprs.com/ and checking the appropriate boxes under "Account Management" and "Email Subscriptions")
- Get automatic updates of due dates using the ROSES-2025 due date Google calendar. Instructions will be available shortly after release at https://science.nasa.gov/researchers/sara/library-and-useful-links (link from the words due date calendar);
- and checking this ROSES-2025 Blog at https://science.nasa.gov/researchers/solicitations/roses-2025.
Frequently asked questions about ROSES-2025 will be posted at https://science.nasa.gov/researchers/sara/faqs/. Further information about specific program elements may be obtained, after the release of ROSES-2025, from the individual Program Officers listed in the Summary of Key Information for each program element in the Appendices of ROSES-2025 and at https://science.nasa.gov/researchers/sara/program-officers-list/.
Subject matter experts are encouraged to sign up to be a volunteer reviewer at https://science.nasa.gov/researchers/volunteer-review-panels.
Questions concerning general ROSES and especially the Summary of Solicitation may be directed to the office of the SMD Deputy Associate Administrator for Research via sara "at" nasa.gov, shared by the members of the office of the SMD Deputy Associate Administrator for Research.
