ROSES25: A.15 Biosphere

The close date above is the date for the Step-2 proposal due date. The Step-1 proposal due date is September 4, 2026. Step-2 proposals cannot be submitted if a Step-1 proposal was not submitted.

NOTICE: Amended July 20, 2026. This amendment adds this new program element to ROSES-2025. This element uses a two-step proposal process (Section 4). Step-1 proposals are due by September 4, 2026, and Step-2 proposals are due November 6, 2026. Any proposal not preceded by an on-time compliant Step-1 proposal will be returned without review. The page limit for the S/T/M section of Step-2 proposals is 12 pages. Proposers to this program element are strongly encouraged to use the optional Earth Science Division template for the required summary table of work effort of the proposal; templates are available at https://science.nasa.gov/researchers/templates-for-earth-science-division-appendix-a-roses-proposals. Proposals submitted to this program will be evaluated using dual anonymous peer review, see Section 4.3 of this program element.

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
