The Coronagraph Instrument on the Nancy Grace Roman Space Telescope is designed to achieve unprecedented high-contrast performance by deploying several key technologies in space for the first time. With its multiple modes, including broadband imaging, spectroscopy, and polarimetry, it will pave the way for future exo-Earth-finding missions and will itself potentially produce groundbreaking exoplanet and disk science. The Coronagraph Instrument is being developed at the Jet Propulsion Laboratory, in collaboration with Goddard Space Flight Center, CNES, MPIA, JAXA, and ESA.

Community information sessions on the Coronagraph Instrument on the Roman Space Telescope were held on October 26 and 28. The purpose of the session was to inform the community about current progress on the Roman Coronagraph Instrument and its capability as a technology demonstrator and potential science instrument. This information may be particularly useful for potential proposers to the Coronagraph Community Participation Program (CPP) element of the Roman Research and Support ROSES solicitation expected later in 2022.

These information session talks contain presentations from the Roman Coronagraph Project on the status and capability of the instrument, from both Coronagraph Science Investigation Teams summarizing their work done and potential future areas of interest, and summaries of additional resources, including open-source simulation tools.
