Astrophysics Biennial Technology Report 2022
APD undertakes space missions to explore the nature of the universe at its largest scales, its earliest moments, and its most extreme conditions; missions that study how galaxies and stars formed and evolved to shape the universe we see today; and missions that seek out and characterize planets and planetary systems orbiting other stars. Since such ambitious missions require technologies that exceed today's state of the art, APD established the SAT program to mature key technologies that enable these future missions, from demonstrated feasibility (i.e., Technology Readiness Level, or TRL, of 3), to the point where they can be incorporated into NASA flight missions (i.e., TRL 6). APD set up three science-themed Programs, COR, ExEP, and PCOS, to address three fundamental questions: “How did we get here?” (COR), “Are we alone?” (ExEP), and “How does the universe work?” (PCOS). The COR, ExEP, and PCOS Program Offices support their respective Programs, including managing SAT and other midTRL-directed projects.
