Who can apply

This opportunity is 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?

• 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 October 15, 2026. See the full posting on NSPIRES for details. NOTICE: September 18, 2026. The instructions regarding biographical sketches and Current and Pending Support in Table D.4-2 have been improved. New text is in bold and deleted text is struck through. NOTICE: Amended August 31, 2026. This amendment releases the final text for this program element, which was previously TBD. Mandatory NOIs are due October 15, 2026, and proposals are due December 3, 2026. There are several major changes since the prior (2022) opportunity, so proposers please read carefully. This program will evaluate proposals using an enhanced dual-anonymous peer review, see Section 5 and the associated "Guidelines for Proposers to ROSES DAPR Programs" document under "Other Documents" on the right side of this NSPIRES page. 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.
