--- ## Description This annual opportunity from NASA's Science Mission Directorate invites proposals for research and technology development in planetary defense, with a focus on detecting, tracking, and characterizing near-Earth objects (NEOs) that could pose a hazard to Earth. The program seeks to advance scientific understanding and mitigation strategies for planetary defense, including both basic and applied research efforts. This call is part of NASA’s omnibus Research Opportunities in Space and Earth Sciences (ROSES) solicitation and is managed under the Planetary Science Division. --- ## Due Dates - Step-1 Proposals Due: September 12, 2025 - Step-2 Proposals Due: November 18, 2025 Step-1 proposals are mandatory; only those who submit a Step-1 proposal may submit a Step-2 proposal. --- ## Funding Amount - Awards are typically for a period of 3 years. - Award size varies depending on the scope and requirements of the proposed research. - Some programs may allow up to 5-year performance periods; others may specify shorter durations. - No cost sharing or matching required. --- ## Eligibility - Proposers must be affiliated with an institution registered in [NSPIRES](https://nspires.nasaprs.com/). - NASA funding is generally limited to U.S. institutions. - Non-U.S. organizations may participate on a no-exchange-of-funds basis or as specified in the program element. - Eligible organizations include government and private entities, for-profit and non-profit, domestic and foreign (with some restrictions). - Refer to the [NASA Grant and Cooperative Agreement Manual (GCAM)](https://www.nasa.gov/grants-policy-and-compliance-team/#Regulations) for detailed eligibility information. --- ## Application Process - This opportunity follows a two-step proposal process: - **Step-1 Proposal:** Brief summary/notice of intent due by September 12, 2025. - **Step-2 Proposal:** Full proposal due by November 18, 2025 (only if Step-1 was submitted). - All proposals must be submitted via [NSPIRES](https://nspires.nasaprs.com/). - For organizations wishing to submit via Grants.gov, notification must be provided at least 30 days before the due date. - Detailed instructions and required forms are available in the program documents: - [Instructions for Submitting a Step-1 Proposal (PDF)](https://nspires.nasaprs.com/external/viewrepositorydocument?cmdocumentid=1051510&solicitationId={1F963989-1A67-FD25-55A3-A0C24A073AEB}&viewSolicitationDocument=1) - [Instructions for Submitting a Step-2 Proposal (PDF)](https://nspires.nasaprs.com/external/viewrepositorydocument?cmdocumentid=1051511&solicitationId={1F963989-1A67-FD25-55A3-A0C24A073AEB}&viewSolicitationDocument=1) --- ## Additional Information - The program has specific requirements for substantial instrument or equipment requests and has updated submission guidelines—see the latest amendment and FAQs for details. - For a full description of the program and its requirements, review the [C.8 Yearly Opportunities for Research in Planetary Defense call (PDF)](https://nspires.nasaprs.com/external/viewrepositorydocument?cmdocumentid=1080954&solicitationId={1F963989-1A67-FD25-55A3-A0C24A073AEB}&viewSolicitationDocument=1). - General rules and context for all ROSES Appendix C elements are described in the [C.1 Planetary Science Research Program Overview (PDF)](https://nspires.nasaprs.com/external/viewrepositorydocument?cmdocumentid=1036500&solicitationId={C92A28D2-9E30-4149-24B7-8A40ED4F564B}&viewSolicitationDocument=1). - Frequently asked questions are available in the [Planetary Science Research Program Overview FAQ (PDF)](https://nspires.nasaprs.com/external/viewrepositorydocument/cmdocumentid=1089623/solicitationId=%7BC92A28D2-9E30-4149-24B7-8A40ED4F564B%7D/viewSolicitationDocument=1/FAQ_R-25_C1.pdf). --- ## External Links - [Program Page on NSPIRES](https://nspires.nasaprs.com/external/solicitations/summary.do?solId={1F963989-1A67-FD25-55A3-A0C24A073AEB}&path=&method=init) - [ROSES-2025 Omnibus Solicitation](https://nspires.nasaprs.com/external/solicitations/summary!init.do?solId=%7B2A1D139B-B9C7-CE8C-2E81-223FD08460F9%7D&path=&redirectURL=) - [ROSES-2025 Summary of Solicitation (PDF)](https://nspires.nasaprs.com/external/viewrepositorydocument?cmdocumentid=1053488&solicitationId={1F963989-1A67-FD25-55A3-A0C24A073AEB}&viewSolicitationDocument=1) - [Table of Due Dates (Table 2, HTML)](https://nspires.nasaprs.com/external/viewrepositorydocument?cmdocumentid=1041497&solicitationId={1F963989-1A67-FD25-55A3-A0C24A073AEB}&viewSolicitationDocument=1) - [NASA Grant and Cooperative Agreement Manual (GCAM)](https://www.nasa.gov/grants-policy-and-compliance-team/#Regulations) - [FAQ for ROSES Proposers](http://science.nasa.gov/researchers/sara/faqs) - [Program Officers List](http://science.nasa.gov/researchers/sara/program-officers-list) --- ## Contact Information | Name | Email | Description | |----------------|------------------------------|-------------------------------------------------| | Julie Ziffer | HQ-YORPD@mail.nasa.gov | Direct questions about this funding announcement | | Kelly Fast | HQ-YORPD@mail.nasa.gov | Direct questions about this funding announcement | | Adelle Helble | HQ-YORPD@mail.nasa.gov | Direct questions about this funding announcement |
