Amendment 27: A.45 Decadal Survey Incubation Final Text and Due Dates

A.45 Decadal Survey Incubation (DSI) is a new program element that was recommended in the 2017 Earth Science Decadal Survey ( and intended to accelerate readiness of high-priority observables needing science requirements refinement, technology development, and/or other advancements prior to cost-effective flight implementation. Two targeted observables (TOs), both with important science objectives and societal applications, were identified for this program: Planetary Boundary Layer (PBL) and Surface Topography and Vegetation (STV). This element supports the development of Earth observing instrument sensor systems, advanced information systems, and enabling science studies to further advance PBL and STV. The intent of DSI is to ultimately enable the next generation of possible measurement approaches, system architectures, and mission concepts to address PBL and STV needs.

ROSES-2021 Amendment 27 releases final text and due dates for A.45 DSI, which was previously "TBD". Notices of Intent to propose are requested by August 17, 2021, and proposals are due October 14, 2021. A preproposal conference will be held Wednesday, August 4, 2021, 1:00-3:00 PM eastern time, see Section 4.3 of the program element text for connect information.

On or about July 16, 2021, this Amendment to the NASA Research Announcement "Research Opportunities in Space and Earth Sciences (ROSES) 2021" (NNH21ZDA001N) will be posted on the NASA research opportunity homepage at
