Nancy Grace Roman Space Telescope Coronagraph Instrument Overview and Status — The major subsystems of the Coronagraph Instrument.2 The optical bench sits above the electronics pallet. The Electronics Heat Transport System (EHTS) transports heat from the electronics to the warm radiator. The Cryogenic Thermal Subsystem provides passive cooling to the detectors. Multi-layer insulation (MLI) provides additional thermal shielding. The Instrument Carrier (IC) is the observatory structure to which Coronagraph is mounted. — astro-ph.EP

The Nancy Grace Roman Space Telescope Coronagraph Instrument is a critical technology demonstrator for NASA’s Habitable Worlds Observatory.

With a predicted visible-light flux ratio detection limit of 1E-8 or better, it will be capable of reaching new areas of parameter space for both gas giant exoplanets and circumstellar disks. It is in the final stages of integration and test at the Jet Propulsion Laboratory, with an anticipated delivery to payload integration in the coming year. This paper will review the instrument systems, observing modes, potential observing applications, and overall progress toward instrument integration and test.
