ROSES 2025: B.8 Heliophysics Spaceflight Science Foundations

The NASA Science Mission Directorate (SMD) is soliciting proposals for the “Heliophysics Spaceflight Science Foundations” element of the ROSES‑2025 omnibus solicitation. This program supports fundamental heliophysics research that can be conducted via spaceflight platforms, including instrument development, data analysis, and theory work. Proposals are evaluated through a dual‑anonymous review process and may be submitted as either a grant or cooperative agreement. The opportunity is open to U.S. institutions (and some non‑U.S. entities under specific conditions) and follows a two‑step submission schedule: a preliminary (Step‑1) proposal due 20 Nov 2026, followed by a full (Step‑2) proposal due 5 Feb 2027. Typical award periods are three years, with funding amounts varying widely based on scope. • Target area: Heliophysics science that leverages spaceflight data or missions. • Funding mechanism: Grant or Cooperative Agreement (NASA SMD). • Eligibility: U.S. research institutions; limited non‑U.S. participation under policy. • Submission timeline: Step‑1 due 20 Nov 2026; Step‑2 due 5 Feb 2027. • Pre‑proposal teleconference: 26 Oct 2026 (optional). • Review: Dual‑anonymous, standard NASA SMD guidelines. • Expected performance period: ~3 years. • No explicit award ceiling; typical ROSES grants range from $0.5 M to $3 M+.
