Roman Space Telescope's Coronagraph Instrument Integration into the Instrument Carrier

The Coronagraph, one of two science instruments, finds it home in NASA's Nancy Grace Roman Telescope Instrument Carrier.

Designed and built by NASA’s Jet Propulsion Laboratory, the Roman Coronagraph will advance scientists’ ability to directly image planets and disks around other stars (exoplanets). Coronagraphs work by blocking light from a bright object, like a star, so that the observer can more easily see a faint object, like a planet.

The Roman Coronagraph is designed to detect planets 100 million times fainter than their stars, or 100 to 1,000 times better than existing space-based coronagraphs. The Roman Coronagraph will be capable of directly imaging reflected starlight from a planet akin to Jupiter in size, temperature, and distance from its parent star.
