Description
Heliophysics Spaceflight Science Foundations is a program element within NASA’s Research Opportunities in Space and Earth Sciences (ROSES)–2025 solicitation, administered by the Science Mission Directorate. Added by an October 8, 2026 amendment, it solicits proposals in heliophysics spaceflight science foundations as part of NASA’s broader portfolio of basic and applied supporting research and technology.
The B.8 program announcement defines the specific research opportunity. Proposals are also subject to the B.1 Heliophysics Research Program Overview and the common requirements in the ROSES-2025 Summary of Solicitation. This competition uses a two-step proposal process and dual-anonymous review, with program-specific preparation instructions and accompanying guidance for ROSES dual-anonymous peer review programs.
