The Mission

This is the official consortium homepage of the CHEOPS mission. CHEOPS is the first S-class mission from ESA and was selected in October 2012 with a launch foreseen in the last quarter of 2019.

CHEOPS stands for CHaracterising ExOPlanet Satellite. It is a small photometric observatory to be launched into low Earth orbit to measure transits of exoplanets. See the «Executive Summary» for a short overview.

Please use the menu for further information. The majority of the homepage is currently only available in English. The menu item «public» is also available in German and French.
