# NASA Opens Heliophysics Research Opportunity

NASA’s ROSES-2025 Amendment 78 opens the B.7 Heliophysics Low-Cost Access to Space (H-LCAS) proposal opportunity for teams developing or applying instruments, technologies, and flight investigations using sounding rockets, high-altitude balloons, and CubeSats. Step-1 proposals are due **November 20, 2026 (43 days from October 8)**, and Step-2 proposals are due March 16, 2027. The opportunity gives research teams and contractors a defined path to propose science and science-enabling investigations using these lower-cost flight platforms.

- Interested teams should review solicitation NNH25ZDA001N-LCAS for proposal requirements and plan around the two submission stages and deadlines.
- The opportunity is relevant to organizations developing spaceflight instruments, technologies, or investigations suited to sounding rockets, high-altitude balloons, or CubeSats.
- Questions about the H-LCAS opportunity can be directed to NASA at hq-hpd-lcas@mail.nasa.gov.
