Amendment 50: C.27 Precursor Science Investigations for Europa Final Text and Due Dates

The goal of the Precursor Science Investigations for Europa (PSI-E) program is to further the understanding of critical topics in Europa exploration in advance of the Europa Clipper mission. This precursor work will provide critical context to enable more efficient analysis of Clipper data by the science community and will help generate discoveries and new questions that will feed into mission planning for the latter half of the prime mission and for any potential extended mission. This will maximize the science return from the radiation-limited lifetime of the Europa Clipper.

ROSES-2022 Amendment 50 releases final text and due dates for C.27 Precursor Science Investigations for Europa (PSI-E), which was released as draft in ROSES-2021. Step-1 proposals are due November 1, 2022, and Step-2 proposals are due December 16, 2022. This program element will be reviewed using Dual-Anonymous Peer Review.

On or about September 16 2022, this Amendment to the NASA Research Announcement "Research Opportunities in Space and Earth Sciences (ROSES) 2022" (NNH22ZDA001N) will be posted on the NASA research opportunity homepage at
