ROSES 2025: A.18 Geosphere

The NASA Science Mission Directorate’s ROSES 2025 omnibus solicitation includes the “A.18 Geosphere” element, which seeks research proposals that advance Earth‑science investigations of the geosphere (e.g., lithosphere, mantle dynamics, crustal processes, and related modeling). Proposers submit a competitive grant or cooperative agreement via Grants.gov; awards are typically three‑year periods (up to five years for some topics). The solicitation is open to U.S. institutions (with limited non‑U.S. participation under specific conditions) and imposes a mandatory Notice of Intent by 11/16/2026. The deadline for full proposals is 01/15/2027. Funding is provided as a grant or cooperative agreement, with no explicit ceiling; typical NASA research grants range from several hundred thousand to a few million dollars. • Target area: Geosphere science (lithosphere, mantle, crustal dynamics, geophysical modeling). • Funding mechanism: Grant or Cooperative Agreement (NASA). • Eligibility: U.S. research institutions (universities, labs, NGOs) – limited foreign participation. • Submission: Grants.gov, with mandatory NOI by 11/16/2026. • Period of performance: Generally 3 years (possible up to 5 years). • Estimated budget: No ceiling stated; historically NASA Earth‑science research grants range $0.5‑5 M.
