Roman in a nutshell

Roman will scan a large patch of the sky in visible to near-infrared light, with its wide field of view and advanced optical design. The mission will provide key insights that will help reveal the nature of dark energy and dark matter and find new exoplanets.

To achieve its science goals, Roman is equipped with a primary mirror of 2.4 m and two instruments: the Wide Field Instrument (WFI) and a Coronagraph Instrument technology demonstrator.

Roman is a NASA-led mission to which ESA contributes as a Mission of Opportunity, providing scientific expertise and guidance to maximise the mission's scientific return. ESA also provides essential hardware and communications support through its deep-space ground station network.
