Description
This opportunity, part of NASA's annual Research Opportunities in Space and Earth Sciences (ROSES), solicits proposals for fundamental and applied research that advances knowledge of the solar system. It is designed to support a broad range of planetary science investigations, including observational, experimental, analytical, theoretical, and technology development work relevant to NASA's Science Mission Directorate. Proposals are evaluated through a dual-anonymous peer review process and are expected to address key scientific questions in planetary science, leveraging data from NASA missions or developing new approaches, tools, or instruments.
