ROSES 2025: B.7 The Heliophysics Low-Cost Access to Space

This NASA ROSES‑2025 program element seeks proposals for low‑cost heliophysics research payloads that can be flown on sub‑orbital platforms. The solicitation uses a two‑step submission process (Step‑1 due November 20 2026, Step‑2 due March 16 2027) and requires an anonymized technical proposal, a Payload Reference Document, and a “Rideshare Opportunity” section. Awards are made as grants or cooperative agreements, typically for a three‑year performance period, and may be up to five years in some cases. The effort supports NASA’s goal of expanding heliophysics science through affordable access to space. • Target audience: U.S. research institutions, universities, and eligible non‑U.S. entities under specific conditions. • Funding mechanism: Grants or cooperative agreements (no contract). • Submission: Two‑step via Grants.gov; Step‑1 (letter of intent) due 20 Nov 2026, full proposal due 16 Mar 2027. • Required deliverables: 20‑page anonymized Science‑Technical‑Management section, Payload Reference Document, rideshare description, traceability matrix (if “science‑enabling‑only”). • Evaluation: Dual anonymous peer review. • Typical award size: Not specified; historically low‑cost access grants range from several hundred thousand to a few million dollars. • Period of performance: Usually 3 years (possible up to 5 years).
