Amendment 91: D.16 Astrophysics Decadal Survey Precursor Science Proposal Due Date Delay.

The emphasis of D.16 Astrophysics Decadal Survey Precursor Science (ADSPS) is on science investigations that will reduce future Great Observatory mission risk and inform mission designs and trades when those activities begin. All three Great Observatory concepts identified in the Astro2020 Decadal Survey Report are in the scope of this activity. The precursor science investigations solicited by this program element may include, but are not limited to, theoretical and computational studies, laboratory astrophysics investigations, archival research, and observational investigations.

ROSES-2022 Amendment 91 delays the proposal due date for this program element to March 28, 2023. Only those who submitted a Notice of Intent by January 20, 2023, are eligible to submit a proposal.

On or about March 21, 2023, 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
