Who can apply

• Others

Proposers must be affiliated with an institution at nspires.nasaprs.com/ and, in general, NASA provides funding only to U.S. institutions. Organizations outside the U.S. that propose on the basis of a policy of no-exchange-of-funds; consult the NASA Grant and Cooperative Agreement Manual (GCAM) (https://www.nasa.gov/grants-policy-and-compliance-team/#Regulations) for specific details. Some NRAs may be issued jointly with a non-U.S. organization, e.g., those concerning guest observing programs for jointly sponsored space science programs, that will contain additional special guidelines for non-U.S. participants. Also reference the GCAM for special instructions for proposals from non-U.S. organizations that involve U.S. personnel for whom NASA support is requested.

About this opportunity

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 8/1/2026 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: Updated July 21, 2026. The Anticipated Award Start Date for last submissions in Table C.2-1 in Section 3.1 has been updated. The requirements for Biographical Sketches and Current and Pending Support in Section 3.5 have been updated, as have the Expected program budget for first year of new awards and Number of new awards pending adequate proposals of merit in Section 6. New text is in bold and deleted text is struck through. NOTICE: Research security training required starting August 5, 2026. All PIs and any Co-Is that would spend ≥ 10% time on a proposed grants or cooperative agreements must certify they have taken research security training. NASA will be satisfied with the four online research security training modules on the National Science Foundation's (NSF) Research Security Training website at https://www.nsf.gov/research-security/training or the SECURE Center condensed version of the four modules at https://www.secure-center.org/ctm NOTICE: Amended July 2, 2026. Table C.2-1: Submission and Review Dates in Section 3.1 has been updated and a new row with a new final cut-off date of November 12, 2026, has been added. In addition, this amendment reminds proposers of two important upcoming process changes: Potential proposers are reminded in Section 3.1 that for any proposal for federal assistance submitted > August 5, 2026, PIs and any Co-Is that would spend > 10% time on a proposed grants or cooperative agreements must certify they have taken research security training. NASA will be satisfied with the four online research security training modules on the National Science Foundation’s (NSF) Research Security Training website at https://www.nsf.gov/research-security/training or the SECURE Center condensed version of the four modules at https://www.secure-center.org/ctm The Summary of Requirements for Expertise and Resources Not Anonymized Document in Section 3.5 was updated to indicate that biographical sketches and current and pending support documents submitted after September 1, 2026 must use the NASA-specific Science Experts Network Curriculum Vitae (SciENcv) format found at https://www.ncbi.nlm.nih.gov/sciencv/ per Grant Notice 26-01. NOTICE: Amended, January 22, 2026. Table C.2-1: Submission and Review Dates in Section 3.1 has been updated and a new final row with a cutoff date of August 1, 2026, has been added. Also, the expected budget and number of new awards in Section 4 have been increased. New text is in bold and deleted text is struck through. NOTICE: Corrected September 9, 2025. NASEM Astrobiology Strategy citation was corrected to 2019 (see Section 1.1.3), reference to the anonymized Table of Work Effort was added to Section 3.2, and HEC request is not included in anonymized proposal (see Section 3.5). New text is in bold and deleted text is struck through. NOTICE: ROSES-25 Amendment 7 makes the following changes to C.1 the Planetary Research Overview: It establishes funding threshold and submission requirements for substantial instrument or equipment requests (Section 3.11), removes the estimated page limit for pilot studies (Section 3.4) and clarifies text on use of spacecraft mission data (Section 3.5). New text is in bold and deleted text is struck through. A Planetary Science Overview FAQ has been posted under other documents on NSPIRES pages for all of Appendix C. NOTICE: Amended August 1, 2025. This amendment makes several changes: It establishes that the anonymized Table of Work Effort and references are outside of the 5-page S/T/M section (see Section 3.2), removes an exclusion regarding data archiving (see Section 2.1), changes the first proposal submission cut-off date for inclusion in the Winter 2025 review to September 15, 2025, changes the second estimated review date to Spring 2026 (see Table C.2-1 in Section 3.1), and removes the HEC requirement in the S/T/M as it appears as a cover page question, see Section 3.2. New text is in bold and deleted text is struck through. 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 sa

Portfolio context — this listing covers more than this opportunity

This opportunity is funded under Assistance Listing 43.001 (“Science”), a broad federal program that made about 1590 new awards per year over the last five fiscal years (median award $168k). Those figures describe that whole portfolio — not this specific solicitation, so we don't show them as if they were this opportunity's track record.

Applicant counts per solicitation are not published by any federal agency — no one can honestly sell you that number.
