Informational change · Description
ROSES 2025: B.7 The Heliophysics Low-Cost Access to Space
- The only substantive edit is to the introduction's first paragraph notice: the "Corrected" date moved from October 15, 2026 to October 16, 2026, and the correction itself changed from removing a spurious cubesat reference to replacing a vestigial cubesat reference with "airborne platforms."
- Applicants should note the wording now says an "airborne platforms" reference replaced the cubesat mention, rather than the reference simply being removed. This clarifies that the intro now points to airborne platforms, which may matter for applicants considering platform type.
- No changes were made to requirements, deadlines (Step-1 November 20, 2026; Step-2 March 16, 2027), page limits, rideshare, traceability matrix, or submission/review rules.
- The synopsis field carries the same correction, so the same clarification applies there.
