ROSES 2025: B.7 The Heliophysics Low-Cost Access to Space

The close date above is the date for the Step-2 proposal due date. The Step-1 proposal due date is November 20, 2026. Step-2 proposals cannot be submitted if a Step-1 proposal was not submitted. NOTICE: Amended October 7, 2026. This amendment adds this new program element to ROSES-2025. Step-1 proposals are due by November 20, 2026, and Step-2 proposals are due March 16, 2027. The page limit for the anonymized central Science-Technical-Management (S/T/M) section of proposals is 20 pages. Proposers must provide a separately uploaded Payload Reference Document (PRD) to allow NASA to best match the research payload needs with multiple compatible flight platforms and identify the greatest suborbital research capabilities and launch flexibilities possible. See Section 1.3.1. New: Proposals must include a “Rideshare Opportunity” section that describes the availability of resources for a rideshare instrument to be included with the flight. See Section 4.4. New: Proposals self-identified as "science-enabling-only" must include an Application of Traceability Matrix, see 4.2.3. New: Proposals will be submitted via a binding two-step submission process, see Section 3. New: Proposals will be evaluated using dual anonymous peer review, so the technical proposal must be anonymized, see Section 5.1. 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...

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.

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...

Most awards have no matching requirement. Specifics about cost sharing and matching resources are described in the NOFO.

Fiscal year 2025: 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.
