CHEOPS exoplanet mission meets key milestones en route to 2017 launch
ESA’s first small Science Programme mission is ready for construction. The implementation phase has started, meaning that the spacecraft has gone from selection to implementation in less than 18 months.
The rapid progress places the CHaracterising ExOPlanet Satellite (CHEOPS) on course for meeting its target of being ready to launch by December 2017.
CHEOPS is the first in a possible class of small missions to be developed as part of ESA's Science Programme. These will be fast turn-around, highly focused missions that complement the Science Programme’s medium and large missions.
CHEOPS will target nearby bright stars that are already known to have exoplanets in orbit around them, in order to provide new insight into the characteristics of those planets.
