CHEOPS Satellite
CHEOPS, the first S-class ESA mission, was successfully launched on December 18, 2019. CHEOPS—CHaracterising ExOPlanet Satellite—is a small photometric observatory which operates in a low Earth orbit. It is the first mission dedicated to search for transits by means of ultrahigh precision photometry on bright stars already known to host planets.
CHEOPS' first light took place on January 29, 2020, and it has been operational since.
