ROSES25: A.15 Biosphere

The National Aeronautics and Space Administration (NASA) has released a funding opportunity for research proposals under the ROSES25 program, specifically for the A.15 Biosphere program element. This program aims to support research in the area of biosphere science, with a focus on understanding the complex interactions between the Earth's biosphere and the environment. Proposals are being solicited for grants or cooperative agreements to support research projects that align with the goals and objectives of the ROSES25 program. The typical period of performance for an award is three years, but some programs may allow up to five years. Proposers must be affiliated with an institution and, in general, NASA provides funding only to U.S. institutions. • Proposals are due by November 6, 2026, with a step-1 proposal due date of September 4, 2026. • Awards will be made as grants, cooperative agreements, or contracts depending on the nature of the work proposed. • Proposers are encouraged to use the optional Earth Science Division template for the required summary table of work effort of the proposal. • Proposals will be evaluated using dual anonymous peer review. • Research security training is required starting August 5, 2026, for all PIs and Co-Is who would spend ≥ 10% time on a proposed grant or cooperative agreement.
