In a clean room at NASA's Jet Propulsion Laboratory in Southern California in October 2023, scientist Vanessa Bailey stands behind the Roman Coronagraph, which has been undergoing testing at the lab. Designed to block starlight and allow scientists to see the faint light from planets outside our solar system, the Coronagraph is a technology demonstration that will be part of NASA's Nancy Grace Roman Space Telescope.

The Roman Coronagraph Instrument was designed and is being built at JPL, which manages the instrument for NASA. Contributions were made by ESA (the European Space Agency), JAXA (the Japanese Aerospace Exploration Agency), the French space agency CNES (Centre National d'Études Spatiales), and the Max Planck Institute for Astronomy in Germany. Caltech, in Pasadena, California, manages JPL for NASA. The Roman Science Support Center at Caltech/IPAC partners with JPL on data management for the Coronagraph and generating the instrument's commands.

The Roman Space Telescope is managed at NASA's Goddard Space Flight Center in Greenbelt, Maryland, with participation by JPL and Caltech/IPAC in Southern California, the Space Telescope Science Institute in Baltimore, and a science team comprising scientists from various research institutions. The primary industrial partners are Ball Aerospace & Technologies Corp. in Boulder, Colorado; L3Harris Technologies in Melbourne, Florida; and Teledyne Scientific & Imaging in Thousand Oaks, California.
