NNH26ZTR001N-26NIAC-A2 NASA Innovative Advanced Concepts (NIAC) Phase II

The close date above is the date ROSES25 closes. The Step-2 due date will be announced at least 60 days before the Step-2 proposal due date. The Step-1 proposal due date is May 1, 2026. Step-2 proposals cannot be submitted if a Step-1 proposal was not submitted. NOTICE: Amended February 11, 2026. This amendment makes two corrections to this program element: The length of the Step-1 Proposal in Section 3.3.1 has been corrected from two pages to three, and the expected budget numbers given in the summary table are per award, per year, not the budget for all of the new awards in the SST. NOTICE: Amended February 3, 2026. This amendment releases the final text for this program element, which was previously TBD. Step-1 proposals are due May 1, 2026. The Step-2 due date will be announced at least 60 days before the Step-2 proposal due date, see Section 3.1. An individual may be Principal Investigator (PI) of one and only one proposal to this program element. There is an exception for multiple submissions per PI only when institutions require oversight for efforts that involve Science PIs. The rules regarding interagency awards described in Section 1.1.1 of B.1 Heliophysics Research Program Overview and Section 7 apply to this program element. Proposals submitted to this program will be evaluated using a dual-anonymous review process. Proposals must be prepared according to the guidelines in Section 2.4.2 and in the associated "Guidelines for Proposers to ROSES DAPR Programs" document under "Other Documents" on the NSPIRES page for this program element. All proposers are strongly encouraged to use the standard SMD template for the Open Science Data Management Plan see https://science.nasa.gov/researchers/sara/faqs/OSDMP This synopsis is a generic summary that is posted for each of the many individual "program elements" in NASA’s Research Opportunities in Space and Earth Sciences (ROSES) – 2025 solicitation. For specific information on this particular program element download and read the PDF of the text of this program element by going to Tables 2 or 3 of ROSES at https://solicitation.nasaprs.com/ROSES2025table2 and https://solicitation.nasaprs.com/ROSES2025table3 , respectively, click the title of the program element of interest, a hypertext link will take you to a page for that particular program element. On that page, on the right side under "Announcement Documents" the link on the bottom will be to the PDF of the text of the call for proposals. For example, if one were interested in the Solar System Science program (NNH25ZDA001N-SCUBED) one would follow the link to the NSPIRES page for that program element and then to read the text of the call one would click on “C.2 Solar System Science (.pdf)” to download the text of the call. If one wanted to set it into the context of the goals, objectives and know the default rules for all elements within Appendix C, the planetary science division, one might download and read “ C.1 Planetary Science Research Program Overview (.pdf) ” from that same page. While the letters and numbers are different for each element within ROSES (A.10, B.3, etc.) the basic configuration is always the same, e.g., the letter indicates the Science Division (A is Earth Science, B is Heliophysics etc.) and whatever the letter, #1 is always the division overview. In 2025, 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 https://solicitation.nasaprs.com/ROSES2025 . The National Aeronautics and Space Administration (NASA) Science Mission Directorate (SMD) released its annual omnibus Research Announcement (NRA), Research Opportunities in Space and Earth Sciences (ROSES) – 2025 (OMB Approval Number 2700-0092, CFDA Number 43.001) on February 21, 2025. In this case "omnibus" means that this NRA has many individual program elements, each with its own due dates and topics. All together these cover the wide range of basic and applied supporting research and technology supported by SMD. Awards will be made as grants, cooperative agreements, or contracts depending on the nature of the work proposed. However, most extramural research awards deriving from ROSES will be grants, and many program elements of ROSES specifically exclude contracts, because contracts would not be appropriate for the nature of the work solicited. Funded Co-Is at government labs will receive inter- or intra-agency transfers . The typical period of performance for an award is three years, but some programs may allow up to five years and others specify shorter periods. In most cases, organizations of every type, Government and private, for profit and not-for-profit, domestic and foreign (with some caveats), may submit proposals without restriction on teaming arrangements. Tables listing the program elements and due dates (Tables 2 and 3 ), a table that provides a very top level summary of proposal contents ( Table 1 ), and the full text of the ROSES-2025 "Summary of Solicitation", may all be found NSPIRES at https://solicitation.nasaprs.com/ROSES2025 . Frequently asked questions for ROSES are posted at http://science.nasa.gov/researchers/sara/faqs . Questions concerning specific program elements should be directed to the point(s) of contact for that particular element, who may be found either at the end of the individual program element in the summary table of key information or on the web list of topics and points of contact at: http://science.nasa.gov/researchers/sara/program-officers-list . General questions concerning ROSES-2025 may be directed to the office of the SMD Deputy Associate Administrator for Research at sara@nasa.gov .

This program element does not have a proposal due date. Proposals may be submitted at any time, pending certain eligibility timing issues related to resubmissions and duplicate proposal avoidance, see the program element text and appropriate overview appendix (e.g., B.1 or C.1). The date shown of 8/31/2026 is the last day that proposals may be submitted subject to the ROSES-25 rules and the current GCAM. The ROSES-26 version of this program element is planned to overlap with this ROSES-25 version by a few weeks, allowing continuous submission of proposals across ROSES years. NOTICE: Amended, January 26, 2026. Sections 1 and 1.1 have been updated to encourage non-governmental organizations new to NASA to partner with NASA centers, and a requirement was added to Section 4 to plan for operation beyond the award period. New text is in bold and deleted text is struck through. NOTICE: Amended, January 22, 2026. The last date for submission of proposals (in Section 7) has been updated to reflect that ROSES-25 will be open until August 2026. Proposals may be submitted at any time until August 31, 2026. New text is in bold and deleted text is struck through. NOTICE: Amended September 22, 2025. This amendment announces that those proposing to Earth Science (ROSES Appendix A) to use the NASA Center for Climate Simulation high-end computing facility must include $0.09/SBU in their budget per the instructions provided in Section 7.3 of ROSES-25 A.1 Earth Science Research Overview . This applies to all open and future program elements in Appendix A (Earth Science) as of 09/22/2025.
