# NASA Opens Geosphere Research Opportunity

NASA’s ROSES-2025 Amendment 77 opens the A.18 Geosphere opportunity for research proposals addressing geohazard forecasting and impacts, resource extraction and deformation, critical mineral deposits and crustal processes, and energy flow from Earth’s core to its surface. A Notice of Intent is mandatory by **November 16, 2026**; proposals are due **January 15, 2027**. NASA will return proposals without review if the NOI is not submitted on time.

- Researchers and organizations pursuing NASA Earth science funding should submit the required NOI by November 16 before preparing a proposal for the January 15 deadline.
- The opportunity covers four research areas, including geohazards, critical minerals, and energy processes; prospective applicants can use these areas to assess project fit and form research teams.
- Questions about the A.18 Geosphere opportunity can be directed to Thorsten Markus at thorsten.markus@nasa.gov.
