ROSES 2025: B.7 The Heliophysics Low-Cost Access to Space
NASA's Heliophysics Low-Cost Access to Space program seeks suborbital research payload proposals, with Step-1 due November 20, 2026, and required before Step-2, due March 16, 2027.
Funder: NASA Headquarters
Due Dates: November 20, 2026 (Step-1) | March 16, 2027 (Step-2)
Funding Amounts: Grants and cooperative agreements; no cost sharing or matching required
Summary: Supports heliophysics research through low-cost access to space, including suborbital research payloads and airborne platforms.
Key Information: A Step-1 proposal is mandatory before Step-2 submission, and technical proposals must be anonymized.
Description
NASA’s Heliophysics Low-Cost Access to Space program is a Science Mission Directorate opportunity within ROSES-2025. It supports heliophysics research involving flight payloads and airborne platforms. The program seeks to match research payload needs with multiple compatible flight platforms, identifying suborbital research capabilities and launch flexibility through a separately submitted Payload Reference Document.
The opportunity uses a binding two-step application process and dual anonymous peer review. Proposals must address resources available for a rideshare instrument to accompany the flight. Projects self-identified as “science-enabling-only” must also include an Application of Traceability Matrix. The B.7 program announcement, B.1 Heliophysics Research Program Overview, and ROSES-2025 Summary of Solicitation together describe the applicable proposal requirements.
