Amendment 44: Delay of Due Dates for D.3 APRA and D.7 SAT

D.3 Astrophysics Research and Analysis (APRA) solicits basic research proposals for investigations that are relevant to NASA's programs in astronomy and astrophysics and includes research over the entire range of photons, gravitational waves, and particle astrophysics.

D.7 Strategic Astrophysics Technology (SAT) supports the maturation of key technologies for potential infusion in spaceflight missions. The SAT program is designed to support the maturation of technologies that have already been demonstrated to be feasible (i.e., TRL 3), to the point where they can be incorporated into NASA flight missions (TRL 6).

ROSES-2023 Amendment 44 announces that the due dates for both D.3 APRA and D.7 SAT have been deferred: Mandatory Notices of Intent are now due December 15, 2023, and proposals are now due January 31, 2024. Changes to the text of APRA and SAT will be provided by amendment in October.

On or about September 14, 2023, this Amendment to the NASA Research Announcement "Research Opportunities in Space and Earth Sciences (ROSES) 2023" (NNH23ZDA001N) will be posted on the NASA research opportunity homepage at
