Astrophysics Strategic Technology Gaps Following the 2020 Decadal Survey

The Decadal Survey on Astronomy and Astrophysics 2020, "Pathways to Discovery in Astronomy and Astrophysics for the 2020s," recommended a suite of compelling missions, including a 6m-class IR/Optical/UV observatory for exoplanet characterization and general astrophysics studies, a far-IR flagship, an X-ray flagship, and three Probe missions.

The proposed launch dates for these are:

Early 2030s for the first Probe (X-ray or far-IR)
Early 2040s for the next Probe (CMB or the one not launched before)
Mid-2040s for the IR/O/UV Great Observatory
The following decade(s) for the far-IR and X-ray Great Observatories.

Such missions require technologies that far exceed today's state of the art. To begin developing and maturing technologies that enable and enhance such missions, NASA established the Strategic Astrophysics Technology (SAT) program. Where needed, direct-funded projects may supplement the SAT program.
