Amendment 50: Heliophysics Flight Opportunities Studies Final Text and Due Date.

The Heliophysics Flight Opportunities Studies (H-FOS) program solicits proposals for up to twelve-month studies to enable application of new technologies (platform and/or instrumentation) to heliophysics flight missions. The H-FOS program supports investigations addressing NASA Heliophysics Science Goals using investigator-developed instrumentation. The goal of H-FOS is to provide an early investment in studies for potential future proposed missions that enable meritorious science investigations. Examples of activities that would be considered for an H-FOS investigation include 1) refinement of scientific methodology for new applications in future space missions, 2) trade studies for implementation, and 3) mission concept studies to determine optimal orbits, mass and power requirements, etc. These examples are not prescriptive or exhaustive; any activities to mature a mission concept is solicited through H-FOS.

ROSES-2020 Amendment 50 releases final text and due dates for B.10 Heliophysics Flight Opportunities Studies which was previously listed as TBD. Notices of intent to propose are not requested. The due date for proposals is December 3, 2020.

On or about September 2, 2020, this Amendment to the NASA Research Announcement "Research Opportunities in Space and Earth Sciences (ROSES) 2020" (NNH20ZDA001N) will be posted on the NASA research opportunity homepage at and will appear on SARA's ROSES blog at:
