CHEOPS – CHaracterising ExOPlanet Satellite
CHEOPS is the first mission dedicated to search for transits of exoplanets by means of ultra-high precision photometry on bright stars already known to host planets. It provides the unique capability of determining accurate radii for a subset of those planets for which the mass has already been estimated from ground-based spectroscopic surveys, providing on-the-fly characterization of exoplanets located almost everywhere in the sky and therefore prime targets for future instruments suited to the spectroscopic characterization of exoplanetary atmospheres.
