ROSES25: B.2 Heliophysics Foundational Research
Due in 10 daysNASA Headquarters · Amount varies
This NASA ROSES-25 Heliophysics Foundational Research opportunity (B.2) is open to U.S. institutions affiliated with NSPIRES, with non-U.S. organizations limited to a no-exchange-of-funds basis. It funds foundational heliophysics research through a two-step process (Step-1 proposals were due May 1, 2026; the close date of August 31, 2026 is when ROSES-25 closes). A Step-2 proposal requires a submitted Step-1 proposal, and review is dual-anonymous. No specific award amount is stated, and this is geared toward research organizations rather than individuals.
