ROSES25: B.2 Heliophysics Foundational Research

The close date above is the date ROSES25 closes. The Step-2 due date will be announced at least 60 days before the Step-2 proposal due date. The Step-1 proposal due date is May 1, 2026. Step-2 proposals cannot be submitted if a Step-1 proposal was not submitted.

NOTICE: Amended February 11, 2026. This amendment makes two corrections to this program element: The length of the Step-1 Proposal in Section 3.3.1 has been corrected from two pages to three, and the expected budget numbers given in the summary table are per award, per year, not the budget for all of the new awards in the SST.

NOTICE: Amended February 3, 2026. This amendment releases the final text for this program element, which was previously TBD. Step-1 proposals are due May 1, 2026. The Step-2 due date will be announced at least 60 days before the Step-2 proposal due date, see Section 3.1.

An individual may be Principal Investigator (PI) of one and only one proposal to this program element. There is an exception for multiple submissions per PI only when institutions require oversight for efforts that involve Science PIs.

The rules regarding interagency awards described in Section 1.1.1 of B.1 Heliophysics Research Program Overview and Section 7 apply to this program element.

Proposals submitted to this program will be evaluated using a dual-anonymous review process. Proposals must be prepared according to the guidelines in Section 2.4.2 and in the associated "Guidelines for Proposers to ROSES DAPR Programs" document under "Other Documents" on the NSPIRES page for this program element.

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
