--- ## Description This opportunity, part of NASA's annual Research Opportunities in Space and Earth Sciences (ROSES), solicits proposals for research to advance the detection, characterization, and theoretical understanding of exoplanets and their systems. Projects may encompass observational, theoretical, laboratory, or technology development work that contributes to NASA's exoplanet science goals. The program aims to foster innovative research that enhances our knowledge of planetary systems beyond our own, their formation, evolution, and potential habitability. --- ## Due Dates - Step-1 Proposal Deadline: December 3, 2025 - Step-2 Proposal Deadline: January 26, 2026 Step-1 proposals are mandatory; only those who submit a Step-1 proposal may submit a Step-2 proposal. --- ## Funding Amount - Typical award duration is 3 years, with some programs allowing up to 5 years or specifying shorter periods. - Funding levels are determined by the scope of the proposed research and available program resources; specific budgets are not pre-set. - Awards may be made as grants or cooperative agreements. --- ## Eligibility - Proposers must be affiliated with an institution registered in [NSPIRES](https://nspires.nasaprs.com/). - NASA typically funds only U.S. institutions. - Non-U.S. organizations may participate on a no-exchange-of-funds basis; see the [NASA Grant and Cooperative Agreement Manual (GCAM)](https://www.nasa.gov/grants-policy-and-compliance-team/#Regulations) for details. - All institution types (government, private, for-profit, not-for-profit, domestic, and foreign with caveats) may submit proposals. - Special restrictions apply to interagency awards; see the solicitation for details. --- ## Application Process - Review the full program element [F.3 Exoplanets Research (PDF)](https://nspires.nasaprs.com/external/viewrepositorydocument?cmdocumentid=1082956&solicitationId={2F7D763F-B1F4-2C89-27C5-B1A961209D3F}&viewSolicitationDocument=1). - Submit a mandatory Step-1 proposal by the Step-1 deadline. - If invited, submit a full Step-2 proposal by the Step-2 deadline. - Detailed proposal preparation and submission instructions are available in the [ROSES-2025 Summary of Solicitation](https://nspires.nasaprs.com/external/viewrepositorydocument?cmdocumentid=1053488&solicitationId={2F7D763F-B1F4-2C89-27C5-B1A961209D3F}&viewSolicitationDocument=1). - Submission is via [NSPIRES](https://nspires.nasaprs.com/) (Grants.gov submission possible only if requested 30+ days in advance). --- ## Additional Information - All program documents, due dates, and amendments are available on the [ROSES-2025 NSPIRES page](https://nspires.nasaprs.com/external/solicitations/summary.do?solId={2F7D763F-B1F4-2C89-27C5-B1A961209D3F}&path=&method=init). - For general ROSES information, see the [NASA SMD ROSES page](https://science.nasa.gov/researchers/solicitations/roses-2025/). - Frequently asked questions: [ROSES FAQ](http://science.nasa.gov/researchers/sara/faqs). - Subscribe to SMD mailing lists and due date calendars via [NSPIRES Account Management](http://nspires.nasaprs.com). --- ## External Links - [NSPIRES Opportunity Summary](https://nspires.nasaprs.com/external/solicitations/summary.do?solId={2F7D763F-B1F4-2C89-27C5-B1A961209D3F}&path=&method=init) - [Full Program Element Text (PDF)](https://nspires.nasaprs.com/external/viewrepositorydocument?cmdocumentid=1082956&solicitationId={2F7D763F-B1F4-2C89-27C5-B1A961209D3F}&viewSolicitationDocument=1) - [ROSES-2025 Summary of Solicitation (PDF)](https://nspires.nasaprs.com/external/viewrepositorydocument?cmdocumentid=1053488&solicitationId={2F7D763F-B1F4-2C89-27C5-B1A961209D3F}&viewSolicitationDocument=1) - [NASA Grant and Cooperative Agreement Manual (GCAM)](https://www.nasa.gov/grants-policy-and-compliance-team/#Regulations) - [ROSES-2025 Table of Due Dates](https://nspires.nasaprs.com/external/viewrepositorydocument?cmdocumentid=1041497&solicitationId={2F7D763F-B1F4-2C89-27C5-B1A961209D3F}&viewSolicitationDocument=1) - [Instructions for Submitting a Step-1 Proposal (PDF)](https://nspires.nasaprs.com/external/viewrepositorydocument?cmdocumentid=1051522&solicitationId={2F7D763F-B1F4-2C89-27C5-B1A961209D3F}&viewSolicitationDocument=1) - [Instructions for Submitting a Step-2 Proposal (PDF)](https://nspires.nasaprs.com/external/viewrepositorydocument?cmdocumentid=1051523&solicitationId={2F7D763F-B1F4-2C89-27C5-B1A961209D3F}&viewSolicitationDocument=1) --- ## Contact Information | Name | Email | Notes | |---------------------|--------------------------|----------------------------------------------------------------------| | John Wisniewski | hq-xrp@mail.nasa.gov | Direct questions about this funding announcement to this address. | | Rebekah Dawson-Rigas| hq-xrp@mail.nasa.gov | | | Galen Fowler | hq-xrp@mail.nasa.gov | | | Joshua Pepper | hq-xrp@mail.nasa.gov | | - General ROSES questions: sara@nasa.gov - Program officer list: [NASA SARA Program Officers](http://science.nasa.gov/researchers/sara/program-officers-list)
