Step-1: September 18, 2025 | Step-2: January 13, 2026

Typical period of performance is 3 years; award size varies by project and program element.

Supports research, science, and applications teams for the TROPICS and PREFIRE Earth Venture missions under NASA's ROSES program.

Step-2 proposals only accepted from those who submitted a Step-1 by the deadline.

--- ## Description This opportunity, part of NASA's annual Research Opportunities in Space and Earth Sciences (ROSES) omnibus, invites proposals for science and applications teams supporting the TROPICS (Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats) and PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) missions. These teams will advance Earth science research and applications by leveraging data from these missions, focusing on atmospheric processes, weather, climate, and polar energy budgets. The solicitation supports a wide range of research, including fundamental science, applied science, and technology development related to the mission objectives. --- ## Due Dates - Step-1 Proposals Due: September 18, 2025 - Step-2 Proposals Due: January 13, 2026 Only applicants who submit a Step-1 proposal by the deadline are eligible to submit a Step-2 proposal. --- ## Funding Amount - Award size: Varies by project scope and program element; no specific ceiling or floor is listed. - Typical period of performance: 3 years (some programs may allow up to 5 years). - Awards will be made as grants or cooperative agreements. - No cost sharing or matching required. --- ## Eligibility - Proposers must be affiliated with an institution registered in [NSPIRES](https://nspires.nasaprs.com/). - NASA generally funds only U.S. institutions. - Non-U.S. organizations may participate under a no-exchange-of-funds policy and must consult the [NASA Grant and Cooperative Agreement Manual (GCAM)](https://www.nasa.gov/grants-policy-and-compliance-team/#Regulations) for details. - All types of organizations (government, private, non-profit, for-profit, domestic, and foreign) may submit proposals, subject to the above caveats. - Teaming arrangements are allowed without restriction. --- ## Application Process - Proposals are submitted in two steps: 1. **Step-1 Proposal**: Required for eligibility; due September 18, 2025. 2. **Step-2 Proposal**: By invitation only for those who submitted Step-1; due January 13, 2026. - Detailed instructions and required forms are available on the [NSPIRES opportunity page](https://nspires.nasaprs.com/external/solicitations/summary.do?solId={B956BA32-22A3-1A3C-F9EE-0684736326E0}&path=&method=init). - Proposals must follow requirements outlined in the [ROSES-2025 Summary of Solicitation](https://nspires.nasaprs.com/external/viewrepositorydocument?cmdocumentid=1053488&solicitationId={B956BA32-22A3-1A3C-F9EE-0684736326E0}&viewSolicitationDocument=1). - Applicants using the NASA Center for Climate Simulation facility must budget $0.09/SBU as per Section 7.3 of the [A.1 Earth Science Research Overview](https://nspires.nasaprs.com/external/viewrepositorydocument?cmdocumentid=1036498&solicitationId={B956BA32-22A3-1A3C-F9EE-0684736326E0}&viewSolicitationDocument=1). --- ## Additional Information - Only those who submit a Step-1 proposal by the deadline may submit a Step-2 proposal. - The opportunity is part of the larger [ROSES-2025](https://solicitation.nasaprs.com/ROSES2025) omnibus, which contains many individual program elements. - Amendments and clarifications are posted on the [ROSES-2025 blog](https://science.nasa.gov/researchers/solicitations/roses-2025/). - Frequently asked questions are available [here](http://science.nasa.gov/researchers/sara/faqs/). - For a checklist of proposal requirements, see [Table 1 ROSES-25 Proposal Checklist](https://nspires.nasaprs.com/external/viewrepositorydocument?cmdocumentid=1041499&solicitationId={B956BA32-22A3-1A3C-F9EE-0684736326E0}&viewSolicitationDocument=1). --- ## External Links - [Full Announcement and Instructions](https://nspires.nasaprs.com/external/solicitations/summary.do?solId={B956BA32-22A3-1A3C-F9EE-0684736326E0}&path=&method=init) - [ROSES-2025 Program Page](https://solicitation.nasaprs.com/ROSES2025) - [A.2 Earth Venture: TROPICS and PREFIRE Science and Applications Teams Call (.pdf)](https://nspires.nasaprs.com/external/viewrepositorydocument?cmdocumentid=1083025&solicitationId={B956BA32-22A3-1A3C-F9EE-0684736326E0}&viewSolicitationDocument=1) - [Instructions for Submitting a Step-1 Proposal](https://nspires.nasaprs.com/external/viewrepositorydocument?cmdocumentid=1080284&solicitationId={B956BA32-22A3-1A3C-F9EE-0684736326E0}&viewSolicitationDocument=1) - [Instructions for Submitting a Step-2 Proposal](https://nspires.nasaprs.com/external/viewrepositorydocument?cmdocumentid=1080285&solicitationId={B956BA32-22A3-1A3C-F9EE-0684736326E0}&viewSolicitationDocument=1) - [NASA Grant and Cooperative Agreement Manual (GCAM)](https://www.nasa.gov/grants-policy-and-compliance-team/#Regulations) - [Program Officers List](http://science.nasa.gov/researchers/sara/program-officers-list/) --- ## Contact Information | Name | Email | Phone | Role/Notes | |--------------|------------------------------|-----------------|--------------------------------------------------------| | Wenying Su | Wenying.Su-1@nasa.gov | (757) 690-3418 | General inquiries, access issues | | Will McCarty | will.mccarty@nasa.gov | (240) 758-8263 | Direct questions about this funding announcement | | SMD Deputy Associate Administrator for Research | sara@nasa.gov | — | General questions about ROSES-2025 |
