About this grant

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. If one wanted to set it into the context of the goals, objectives and know the default rules for all...

Eligibility (from the notice)

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 the program (43.001)

Science — SMD

How applications are judged

Unless otherwise specified in the NOFO, the evaluation criteria considered in evaluating a proposal are intrinsic merit, relevance, and cost. Intrinsic Merit includes the consideration of the following factors, as applicable to the particular proposal 1) The scientific quality of the proposed project, including, but not limited to, the scientific rationale and the expected significance and/or impact of the proposed work. 2) Overall, technical quality of the proposed work, includes, but is not limited to, the quality of the management plan and project timeline for carrying out the work and the effectiveness and resilience of the proposed experimental designs, methods, techniques, and approaches for achieving the proposed goals and/or objectives. 3) The qualifications, capabilities, and expertise of personnel demonstrated by the proposal (e.g., publications, delivered products, and other measures of productivity and/or experience) that would affect the likelihood of achieving the objectives. 4) Facilities, instruments, equipment and other resources or support systems presented in the proposal that would affect the likelihood of achieving the proposed objectives. A proposal's relevance includes the consideration of the potential contribution to NASA's mission as expressed in its most recent NASA strategic plans and the permitted scope and specific objectives and goals given in the funding announcement. Cost of a proposed effort includes the reasonableness of the proposed...

Examples of funded projects

Fiscal Year2025: The focus of the BioS-ENDURES Consortium is innovation, acceleration, and implementation of space biology specific knowledge and technology centered on human-plant-microbiome relationships to enable a durable human presence in low Earth orbit and beyond. Studying fundamental relationships between humans, plants, and their microbiomes under space flight conditions will reveal new biological mechanisms that will address needs for sustainability and risk mitigation in space exploration. A more thorough understanding is needed of mechanisms underlying responses to space-relevant stressors (ionizing radiation, microgravity, circadian disruption, abiotics, and biotics) to both humans and plant food sources and what role microbiomes may play in shaping those responses. Relationships between microorganisms and humans in isolated and constrained environments such as space habitats must be better understood to enable successful long-term habitation in space. Human/animal, plant, and microbial biologists will work together to ensure an integrated view of the space flight biosphere by enhancing data acquisition, modeling, and testing.Fiscal Year2026: SMD publishes...
