Description
A.15 Biosphere is an Earth Science program element in NASA’s Research Opportunities in Space and Earth Sciences (ROSES)-2025 solicitation, administered by the Science Mission Directorate. Its program contacts cover biodiversity, land cover and land use change, ocean biology and biogeochemistry, and terrestrial ecology. ROSES supports basic and applied research and technology across NASA’s science portfolio, with individual program elements defining their own research topics and requirements.
This opportunity uses a two-step proposal process and dual anonymous peer review. The A.15 Biosphere announcement defines the specific research opportunity, while the A.1 Earth Science Research Program Overview and ROSES Summary of Solicitation provide division-wide and common proposal requirements. Funding instruments listed for this opportunity are grants and cooperative agreements.
