Who can apply

This opportunity was open to the applicants described in the notice.

• Others (see text field entitled "Additional Information on Eligibility" for clarification)

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.

Is this a realistic fit?

• Most of the program's money (49% over five years) went to nonprofits.
• No cost sharing or match is required.

What the grant funds

PLEASE NOTE: this program has MANDATORY Notices of Intent, which are due via NSPIRES by September 10, 2026. See the full posting on NSPIRES for details. NOTICE: Corrected, August 28, 2026. The Open Science and Data Management Plan was added to Table D.8-1 in Section 3.4. New text is in bold. The due dates remain unchanged. NOTICE: Amended July 27, 2026. This amendment presents a new program element in ROSES-2025. Mandatory NOIs (see Section 3.1) are due by September 10, 2026, and proposals are due by October 26, 2026. The 7-page limit to the S/T/M Section and required content of proposals to this program element differ in several ways from the defaults set in the ROSES-2025 Summary of Solicitation (see Section 3). 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 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.
