D.6 Astrophysics Research and Analysis Program (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) is designed to support the maturation of key technologies for which feasibility has already been demonstrated (i.e., TRL 3), for potential infusion in spaceflight missions (TRL 6).

ROSES-2025 Amendment 56 releases final text and due dates for D.6 APRA and D.7 SAT.
